Description

  The present invention relates to a support device for a vehicle power unit, and more particularly to a vehicle in which a torque rod for connecting a power unit and a vehicle body can be stably attached to an engine body without changing the shape or plate thickness of an oil pan. The present invention relates to a power unit support device.

The vehicle power unit support device is placed horizontally in the engine room, the right and left sides of the power unit are supported on the vehicle body by a pendulum engine mount, and the rear side of the power unit is supported on the vehicle body by a torque rod. There is something to install. One end of the torque rod is fastened to a cylinder block and an oil pan of the engine body constituting the engine of the power unit, and the other end is fastened to a subframe constituting the vehicle body.
Generally, the plate thickness dimension of the oil pan is smaller than the plate thickness dimension of the cylinder block. For this reason, when a member that transmits a load, such as the torque rod, is attached to the oil pan, the thickness of the region to which the member of the oil pan is attached is suddenly increased so that the oil pan does not deform. It is necessary to concentrate or provide ribs. As a result, it was necessary to change the shape of the existing oil pan exclusively.

Therefore, a conventional power unit support device for a vehicle has a structure in which an oil pan is attached to a lower portion of a cylinder block composed of an upper block and a lower block, and the rear portion of the oil pan and a subframe of the vehicle body are connected by a torque rod. It is disclosed. (Japanese Patent Laid-Open No. 2007-186202)
Further, in the conventional vehicle power unit, an oil pan is attached to the lower part of the cylinder block, and an oil filter attached to the front side of the cylinder block is arranged to be located on the front side of the oil pan. A structure in which the tube is in close proximity is disclosed. (Japanese Patent Laid-Open No. 2006-52700)

However, in the support device of Patent Document 1, in order to stably support the torque rod on the oil pan, the thickness of the portion of the oil pan to which the torque rod is attached is increased to such an extent that the torque rod can be supported. There was a need. As a result, it is necessary to change the shape of the existing oil pan that does not have a torque rod attached to a dedicated oil pan that can be fitted with a torque rod. The work burden was increasing.
In addition, when the engine is started from a state where the vehicle is left for a long time, there is a possibility that air has accumulated in the oil strainer in the oil pan, and this suction of air causes noise (noise), There is a concern that the inhalation sound leaks from the oil pan, giving the driver anxiety and discomfort.

In the vehicle power unit of Patent Document 2, since the front end portion of the catalytic converter protrudes forward of the vehicle from the front end portion of the oil filter, hot air from the catalytic converter flows to the front portion of the oil filter. Then, the front part of the oil filter is exposed to hot air, and the front part of the oil filter may be heated. Further, since the catalytic converter or the exhaust pipe and the oil filter are close to each other, the hot air in the catalytic converter or the exhaust pipe is There is a possibility that hot air is transmitted to the vehicle width direction side of the oil filter in the vehicle width direction, and the side surface of the oil filter that approaches the exhaust pipe in the vehicle width direction is heated.

  The present invention provides a vehicle power unit support device that protects an oil filter from heat damage from an exhaust pipe while suppressing noise of the oil pan, and without changing the shape and plate thickness of the oil pan. The purpose is to stably arrange the power unit.

  According to the present invention, a power unit having an engine main body constituting an engine and a transmission coupled to an end portion in the crank axis direction of the engine main body is mounted horizontally in an engine room of a vehicle, and an exhaust is disposed on the front side of the engine main body. A manifold is attached, and an exhaust pipe extending downward in the vehicle is attached to the exhaust manifold. The engine body includes a cylinder block and an oil pan below the cylinder block, and the exhaust pipe is disposed on the front side of the oil pan. A vehicle in which an oil filter that filters oil supplied to the power unit is disposed with a predetermined gap on the outer side in the vehicle width direction from the vehicle, and a torque rod that connects the power unit and the vehicle body is disposed on the rear side of the oil pan. In the power unit support device, the front side and the rear side of the cylinder block A front mounting portion and a rear mounting portion are provided, extending in the vehicle upward direction on the vehicle front side of the oil filter so as to cover the outer peripheral surface of the oil pan from the outside, and extending in the vehicle rear direction on the lower side of the oil pan. And a bracket extending in the vehicle upward direction on the vehicle rear side of the oil pan and extending to the vehicle front side on the lower side of the oil pan and connected to the front portion, and a front portion of the bracket The rear part is fastened to the front side mounting part and the rear side mounting part of the cylinder block, respectively, and an opening is provided in at least a part of the front part of the bracket and overlapping the oil filter in the vehicle longitudinal direction. A bracket side fastening portion to which a rod side fastening portion of the torque rod is fastened is provided at the rear portion of the bracket.

In this invention, since the outer peripheral surface of the oil pan is covered from the outside by the bracket, it is possible to suppress the noise generated in the oil pan by the bracket from being transmitted to the vehicle interior behind the vehicle. As a result, it is possible to prevent the driver or the like from feeling uneasy or uncomfortable.
Further, according to the present invention, the front part and the rear part of the bracket covering the outer peripheral surface of the oil pan are fastened to the front mounting part and the rear mounting part provided in the cylinder block, and the rear part of the bracket and the vehicle body are connected by a torque rod. Therefore, it is not necessary to fasten the torque rod directly to the outer peripheral surface of the oil pan. Therefore, it is not necessary to increase the thickness of the oil pan or change the shape, which is necessary in the conventional structure for fastening the torque rod to the oil pan.
As a result, the torque rod can be attached to the power unit using the existing oil pan, and the design change of the oil pan necessary for attaching the torque rod becomes unnecessary, and the work load on the designer can be reduced.
In such a structure, since the bracket is fastened to the cylinder block instead of the oil pan, the bracket is held by the cylinder block having a relatively thick plate thickness than the oil pan.
As a result, the bracket can be stably attached to the cylinder block, and an increase in vibration of the torque rod and deformation of the bracket can be prevented.
Furthermore, in the present invention, since the opening is formed in the front portion of the bracket and overlapping the oil filter in the vehicle front-rear direction, when the engine is viewed from the front of the vehicle, a part of the oil filter is opened from the opening. Is exposed, while other areas are covered by the front of the bracket.
Therefore, when the traveling wind flows into the engine room from the front of the vehicle, the traveling wind flows into the opening of the bracket, sprays the traveling wind on the oil filter disposed in the gap between the bracket and the oil pan, The oil filter can be cooled.
Even when the hot air in the exhaust pipe drifts to the front side of the oil filter and flows to the oil filter in the area covered by the front part of the bracket in the oil filter, the hot air in the exhaust pipe The flow of hot air can be blocked at the front of the bracket so that it does not reach the oil filter.
As a result, the oil filter can be protected from heat damage caused by hot air in the exhaust pipe.

As shown in FIGS. 2 and 5, the support device 33 is provided with a front mounting portion 37 and a rear mounting portion 38 on the front side and the rear side of the cylinder block 15, respectively. The front mounting portion 37 is integrally provided at the lower front side of the cylinder block 15. The rear attachment portion 38 is provided separately at the lower rear portion of the cylinder block 15 and is attached to the attachment boss portion 39 of the cylinder block 15 with attachment bolts 40.
The support device 33 is mounted with a bracket 41 disposed so as to cover the front side, the lower side, and the rear side of the outer peripheral surface of the oil pan 18 from the outside. The bracket 41 has a front part 42 and a rear part 43.
As shown in FIGS. 1 and 2, the front portion 42 of the bracket 41 extends to the front mounting portion 37 of the cylinder block 15 toward the vehicle front side of the oil filter 32 and below the oil pan 18. The plate has a plate shape extending toward the middle of the lower side wall 25 toward the rear of the vehicle, and is formed in a substantially inverted L shape in a side view. The front portion 42 is provided with a front attachment portion 44 fastened to the front attachment portion 37 at the upper end, and a front connection portion 45 fastened to the rear portion 43 at the rear end, respectively on both sides in the width direction intersecting with the extending direction.

As shown in FIGS. 3 and 5, the rear portion 43 of the bracket 41 extends on the vehicle rear side of the oil pan 18 toward the vehicle upper direction to the rear mounting portion 38 of the cylinder block 15, and on the lower side of the oil pan 18. Thus, it is a plate shape that extends to the middle of the lower side wall 25 toward the front of the vehicle, and is formed in a substantially L shape in a side view. The rear portion 43 is provided with a rear attachment portion 48 fastened to the rear attachment portion 38 at the upper end, a rear connection portion 49 fastened to the front connection portion 45 at the front end, and on both sides in the width direction intersecting with the extending direction. Plate-shaped side portions 50 and 51 are erected.
The bracket 41 is formed in a substantially U shape in a side view by fastening the rear connection portion 49 of the rear portion 43 to the front connection portion 45 of the front portion 42 with the fastening bolt 52. As shown in FIG. 5, the substantially U-shaped bracket 41 fastens the front mounting portion 44 of the front portion 42 to the front mounting portion 37 of the cylinder block 15 with a fastening bolt 53 so as to cover the oil filter 32. It is attached to the engine body 13 by fastening the rear attachment portion 48 of the rear portion 43 to the cylinder block 15 with a fastening bolt 54 so as to cover the oil strainer 30 disposed in the pan 18.
As shown in FIG. 4, the bracket 41 attached to the engine body 13 is formed with an opening 55 in the front portion 42 and in at least a partial region of the portion overlapping the oil filter 32 in the vehicle front-rear direction. ing. Further, as shown in FIG. 5, a bracket side fastening portion 56 to which the torque rod 34 is fastened is provided at the lower portion of the rear portion 43 of the bracket 41. The rod side fastening portion 36 of the torque rod 34 is fastened to the bracket side fastening portion 56 with fastening bolts 57. The torque rod 34 is fastened by a fastening bolt 59 to a subframe side fastening portion 58 provided with a rod side fastening portion 35 in the subframe 7.

Thus, as shown in FIG. 5, the support device 33 of the power unit 11 covers the front side, the lower side, and the rear side of the outer peripheral surface of the oil pan 18 from the outside with the bracket 41. Generated noise, for example, when the operation is started from the state where the vehicle 1 is left for a long time, air suction sound (suction sound) generated from the oil strainer 30 is transmitted from the oil pan 18 into the vehicle interior 9 behind the vehicle. Can be suppressed. As a result, it is possible to prevent the driver or the like from feeling uneasy or uncomfortable.
2 and 3, the front portion 42 and the rear portion 43 of the bracket 41 that covers the outer peripheral surface of the oil pan 18 are fastened to the front side mounting portion 37 and the rear side mounting portion 38 provided in the cylinder block 15. In addition, since the rear portion 43 of the bracket 41 and the subframe 7 of the vehicle body can be connected by the torque rod 34, it is not necessary to directly fasten the torque rod 34 to the outer peripheral surface of the oil pan 18. Therefore, it is not necessary to increase the thickness of the oil pan 18 or change the shape, which is necessary in the conventional structure for fastening the torque rod 34 to the oil pan 18.
As a result, the support device 33 can attach the torque rod 34 to the power unit 11 using an existing oil pan, and the design change of the oil pan 18 necessary for attaching the torque rod 34 is not required. Work burden can be reduced.
Further, in such a structure, since the bracket 41 is fastened to the cylinder block 15 instead of the oil pan 18, the bracket 41 is held by the cylinder block 15 that is relatively thicker than the oil pan 18.
Accordingly, the support device 33 can stably attach the bracket 41 to the cylinder block 15, and can prevent an increase in vibration of the torque rod 34 and deformation of the bracket 41.

Further, as shown in FIGS. 4 and 5, the support device 33 has a front portion 42 of the bracket 41, and an opening 55 is formed at a portion overlapping the oil filter 32 in the vehicle front-rear direction. When the engine 12 is viewed from the front, a part of the oil filter 32 is exposed from the opening 55, while the other region is covered by the front portion 42 of the bracket 41.
Therefore, as shown by arrows in FIGS. 4 and 5, when the traveling wind flows into the engine room 8 from the front of the vehicle, the traveling wind flows into the opening 55 of the bracket 41 and the bracket 41 and the oil pan 18. The oil filter 32 can be cooled by blowing traveling air to the oil filter 32 disposed in the gap.
In the region covered by the front portion 42 of the bracket 41 in the oil filter 32, the hot air in the exhaust pipe 24 (or the catalytic converter 23) drifts to the front side of the oil filter 32 and flows to the oil filter 32. Even in this case, the flow of hot air can be blocked by the front portion 42 of the bracket 41 so that the hot air in the exhaust pipe 24 is not transmitted to the oil filter 32.
Thus, the support device 33 can protect the oil filter 32 from heat damage caused by hot air in the exhaust pipe 24.

As shown in FIGS. 1 and 4, the support device 33 of the power unit 11 defines a space S1 in which the oil filter 32 is disposed and a space S2 in which the exhaust pipe 24 is disposed in the front portion 42 of the bracket 41. A vertical wall portion 60 is provided.
As a result, the support device 33 causes the hot air in the exhaust pipe 24 (or the catalytic converter 23) to move toward the oil filter 32 in the vehicle width direction by the vertical wall portion 60 that partitions the oil filter 32 and the exhaust pipe 24. Even if it flows, the vertical wall 60 provided in the front part 42 of the bracket 41 can block the flow of hot air to the oil filter side.
Thereby, the oil filter 32 can be protected from heat damage of the exhaust pipe 24 (or the catalytic converter 23).
Further, since the vertical wall portion 60 is formed in the front portion 42 of the bracket 41, the vertical wall portion 60 can serve as a reinforcing material (rib) of the bracket 41.
As a result, even if a load is applied from the torque rod 34 to the bracket 41, it is possible to suppress the vibration of the entire bracket at the vertical wall portion 60 and to stabilize the torque rod 34.
Furthermore, even when the traveling wind that has flowed into the engine room 7 hits the bracket 41 and tries to flow toward the exhaust pipe 24, the flow of the traveling wind is regulated by the vertical wall portion 60, and as much as possible. The traveling wind can be guided to the opening 55 of the front portion 42, and the oil filter 32 can be reliably cooled.

As shown in FIG. 1, when the engine 12 is viewed from the front of the vehicle, the support device 33 of the power unit 11 is oriented toward the exhaust pipe 24 in the vehicle width direction with respect to the vehicle width direction center portion of the oil filter 32. The side surface 61 of the bracket 41 is covered with the front portion 42 of the bracket 41, while the side surface 62 of the oil filter 32 facing away from the exhaust pipe 24 in the vehicle width direction is formed on the front portion 42 of the bracket 41. It is opened by the opening 55.
In general, the side surface 61 of the oil filter 32 facing the exhaust pipe 24 is likely to receive hot air from the exhaust pipe 24 (or the catalytic converter 23). On the other hand, the side surface 62 of the oil filter 32 facing away from the exhaust pipe 24 is less likely to receive hot air than the side face of the oil filter 32 facing closer to the exhaust pipe 24 and is less susceptible to hot air.
Therefore, the support device 33 is close to the exhaust pipe 24 in the vehicle width direction with respect to the side surface 61 of the oil filter 32 (that is, the vehicle width direction central portion) that is easily subjected to hot air from the exhaust pipe 24 (or the catalytic converter 23). By covering the facing side surface 61) with the front portion 42 of the bracket 41, the hot air in the exhaust pipe 24 (or the catalytic converter 23) flows from the front side of the vehicle to the side surface 61 facing the exhaust pipe 24 of the oil filter 32. Even so, hot air in the exhaust pipe 24 (or the catalytic converter 23) can be shielded by the front portion 42 of the bracket 41.
Since the support device 33 has a side surface 62 facing away from the exhaust pipe 24 with respect to the vehicle width direction center portion of the oil filter 32, the support device 33 is opened by an opening portion 55 formed in the front portion 42 of the bracket 41, so The introduced traveling wind flows into the opening 55 of the front portion 42, and the traveling wind can be poured into the gap between the bracket 41 and the oil pan 18.
As a result, traveling wind can be blown onto the oil filter 32, and the oil filter 32 can be prevented from being heated by hot air from the exhaust pipe 24.

As shown in FIG. 5, the support device 33 of the power unit 11 forms a gap S3 between the front part 42 and the rear part 43 of the bracket 41 and the lower side wall 25, front side wall 26, and rear side wall 27 of the oil pan 18. Yes. The clearance S <b> 3 is set such that the bracket 41 that vibrates does not come into contact with the oil pan 18 when the bracket 41 vibrates via the torque rod 34.
As described above, the support device 33 prevents the bracket 41 from contacting the oil pan 18 even if the bracket 41 is displaced or vibrated by the torque rod 34 due to the gap S3 formed between the bracket 41 and the oil pan 18. Can be prevented.
As a result, the load from the torque rod 34 is not directly transmitted to the oil pan 18, and an extra load can be prevented from being applied to the oil pan 18 itself.
Therefore, even if the torque rod 34 is attached to the power unit 11, it is not necessary to excessively increase the thickness of the oil pan 18 or change the shape of the oil pan 18.

As shown in FIG. 3, the support device 33 of the power unit 11 overlaps the suction port 31 of the oil strainer 30 disposed at least in the oil pan 18 with the rear portion 43 of the bracket 41 when the engine 12 is viewed from the back of the vehicle. It is arranged.
As described above, the support device 33 is arranged so that the rear portion 43 of the bracket 41 overlaps at least the suction port 31 of the oil strainer 30, and therefore, as shown in FIG. 5, on the vehicle rear side of the oil strainer 30, The rear side wall 27 and the rear portion 43 of the bracket 41 form a double wall structure.
As a result, when the suction sound generated when the suction port 31 of the oil strainer 30 sucks air is about to flow to the inside of the passenger compartment 9 at the rear of the vehicle, the rear side wall 27 of the oil pan 18 and the rear portion 43 of the bracket 41. Thus, it is possible to prevent the inhalation sound from leaking into the passenger compartment 9.

FIG. 6 shows a modification of the support device 33 of the power unit 11. In FIG. 6, the support device 33 has a side cover 63 attached to a bracket 41. The side cover 63 covers the side wall 46 and the rear part of the front part 42 of the bracket 41 so as to cover one side wall 28 (see FIG. 4) of the oil pan 18 positioned at one end of the engine body 13 in the crank axis A direction. It is attached to 43 side portions 50.
Since the support device 33 has the side cover 63 attached to the side portions 46 and 50 of the bracket 41 formed in a substantially U shape in a side view, the side cover 63 serves as a reinforcing member (rib) of the bracket 41. Even if a load is applied to the bracket 41 from the torque rod 34, it is possible to suppress the vibration of the entire bracket 41 by the side cover 63 and to stabilize the torque rod 34.
Further, when the suction sound generated when the suction port 31 of the oil strainer 30 sucks in the air tries to flow backward from the side of the vehicle and flow into the interior of the passenger compartment 9 behind the vehicle, The side cover 63 attached to the bracket 41 so as to cover the side wall 28 can prevent the intake sound from leaking into the vehicle interior 9.

  The present invention protects the oil filter from heat damage from the exhaust pipe while suppressing the noise of the oil pan, and stably arranges the torque rod on the power unit without changing the shape or thickness of the oil pan. The present invention can be applied not only to a power unit in which a transmission is connected to an engine but also to a power unit in which a motor is connected to an engine.
