Description

Locomotive shock absorber configuration

The invention relates to a shock absorber arrangement of a locomotive, in particular to a shock absorber arrangement of a locomotive which can avoid the limitation of the storage space of the locomotive compartment downwardly extending, thereby improving the utility of the locomotive.

According to the locomotive, the air filter has a large volume, so as to enhance the effect of filtering the outside air, the shock absorber disposed beside the air cleaner is disposed on the other side along the vehicle width direction. In order to make room for the increase in the volume of the air filter.

As shown in FIG. 1 and FIG. 2, it is a TWI33917 patent case in which the air cleaner A and the shock absorber B are respectively disposed on the left and right sides of the locomotive along the vehicle width direction, and the shock absorber B is located in the storage box C. Below the bottom, that is, the storage box C is located between the shock absorber B and the seat cushion D.

According to the above configuration, the TWI33917 patent allows the air cleaner A to make room for installation, thereby increasing the volume of the air cleaner A. However, the shock absorber B is located below the storage box C, and the storage box C is located between the shock absorber B and the seat cushion D, thereby causing the space in which the storage box C extends downward. The limitation of the shock absorber B thus causes a serious limitation of the space in which the storage box C can be placed.

The reason is how to provide a locomotive shock absorber configuration, in order to increase the volume of the air filter, and to avoid restrictions on the storage space of the storage box, which has been urgently solved for the locomotive industry. The subject.

The main object of the present invention is to provide a shock absorber configuration of a locomotive, which mainly overcomes the configuration of the conventional locomotive shock absorber, and easily interferes with the lack of volume increase of the air cleaner or the storage box.

The main technical means for achieving the above object is to provide a shock absorber configuration of a locomotive, the locomotive has a frame unit and a storage box disposed on the frame unit, and the frame unit is suspended a swinging power unit, the swing power unit comprises at least an engine body and a transmission box integrally formed with the engine body; the air box is provided with an air filter; the engine body of the swing power unit is driven The rear side of the box is provided with a rear fork unit opposite to the rear wheel, the rear fork unit and the air cleaner are respectively located on the left side and the right side of the locomotive along the vehicle width direction; the frame unit has a side frame, the side frame A shock absorber is disposed between the frame and the rear fork unit, and the shock absorber and the air cleaner are respectively located on the left side and the right side of the locomotive along the vehicle width direction, and the shock absorber is located in a plan view. The side of the glove box is arranged in a non-overlapping manner with the glove box.

The above-mentioned technical means can achieve the effect that the shock absorber is disposed between the side frame and the rear fork unit obliquely toward the front of the vehicle body, and is viewed from a plan view. The shock absorber is located below the side frame; more specifically, the shock absorber and the air cleaner are respectively located on the left side and the right side of the locomotive along the vehicle width direction, whereby the shock absorber is located in the storage box On the side of the side, the storage space extending downward from the storage box is not restricted by the shock absorber, thereby improving the utility of the locomotive.

In order to make it easier for the examiner to understand the structure of the present invention and the effects that can be achieved, the following description is in conjunction with the drawings; first, as shown in Figures 3 and 4, the frame unit 2 of the locomotive 1 is suspended and has a swingable The oscillating power unit 3 includes at least an engine body 31 and a transmission box 32 integrally formed with the engine body 31. The transmission box 32 is provided with a filterable outside air and fresh air for the The engine body 31 is ignited by the air cleaner 4; the engine body 31 of the oscillating power unit 3 is provided with a rear fork unit 5 on the other side of the transmission case 32 with respect to the rear wheel 6, more specifically, the rear The fork unit 5 and the air cleaner 4 are respectively located on the left side and the right side of the locomotive 1 in the vehicle width direction; the engine body 31 is disposed on the same side of the rear fork unit 5, and is provided for the engine body 31 to be discharged after being exploded. An exhaust device 311 for exhaust gas; a rear wheel 6 is attached to the rear end of the transmission case 32.

As shown in FIG. 3, FIG. 4 and FIG. 5, the frame unit 2 has at least a pair of left and right side frames 21 extending toward the rear of the vehicle body, and the frame unit 2 is provided with a storage box 7 for the storage box 7 There is a seat cushion 71 for the driver to ride, and a shock absorber 8 is disposed between the side frame 21 and the rear fork unit 5. The front end 81 of the shock absorber 8 has a front locking portion 811. The lock portion 811 is coupled to the connection portion 211 of the side frame 21, and the connection portion 211 It is located on the curved portion 21a of the side frame 21, that is, the front end 81 of the shock absorber 8 is coupled to the curved portion 21a of the side frame 21, and the rear end 82 of the shock absorber 8 has a rear lock In the portion 821, the rear lock portion 821 is coupled to the joint base 51 of the rear fork unit 5.

As shown in FIGS. 3 and 5, the rear lock portion 821 of the shock absorber 8 is located along the vehicle.
