Description
Technical field
The present invention relates to the components of automobile driving axle, and in particular to a kind of automobile right driving axle medial support structures.
Background technique
In current most of vehicles, in order to solve the problems such as too long bring of right driving axle is vibrated and interfered, use
It is one intermediate supports of increase on right driving axle, as shown in Figure 1, existing automobile right driving axle medial support structures include axis
The bearing spider 2 of 5, bearing snap spring 4 and fixed installation on the engine is held, drive shaft shaft 1 is supported on bearing branch by bearing 5
In the shaft pilot hole of seat 2, and pass through 4 axial limiting of bearing snap spring.Due to the installation site of right driving axle medial support structures
Near exhaust pipe, the heat that exhaust pipe distributes can make medial support structures constant temperature increase, while bearing 5 rotation when from
Body temperature can also increase, and the natural flowing by air is radiated, and effect is bad, and in addition bearing 5 is exposed in shaft pilot hole, extraneous
Dust and muddy water can enter bearing 5, temperature, dust and muddy water can make the working environment of bearing 5 continuous worsening, reduce bearing 5
Service life, and generate the failures such as bearing abnormal noise and clamping stagnation.
Summary of the invention
The object of the present invention is to provide a kind of automobile right driving axle medial support structures, to improve heat dissipation effect, and avoid
Dust and muddy water enter bearing.
Automobile right driving axle medial support structures of the present invention, including bearing, bearing snap spring and it is fixedly mounted on hair
Bearing spider in motivation, drive shaft shaft passes through bearing support in the shaft pilot hole of bearing spider, and passes through bearing card
Spring axial limiting further includes the first dustproof cover and the second dustproof cover, and the first dustproof cover is located at the side of bearing, and covers in drive shaft
It on shaft, can be rotated under the drive of drive shaft shaft, the second dustproof cover is located at the other side of bearing, and covers in drive shaft shaft
On, it can be rotated under the drive of drive shaft shaft, the second dustproof cover is in flaabellum shape, along the circumferential direction equal by multiple identical blades
Even oblique arrangement composition, adjacent two blade partly overlap on the axis direction of drive shaft shaft.
In order to further reduce bearing temperature, keep heat dissipation effect more preferable, the shaft pilot hole of the bearing spider
Hole wall offers a plurality of along the circumferential direction evenly arranged ventilation groove, the length of every ventilation groove and the shaft pilot hole
Equal length.
When drive shaft shaft rotates, the first dustproof cover, the second dustproof cover is driven to rotate together, the first dustproof cover, second prevent
Dirt lid plays dustproof effect, avoids dust and muddy water enters bearing, while when the rotation of the second dustproof cover, blade high speed rotation
It flows air-flow quickly, the heat assembled due to generation when exhaust pipe is distributed with bearing in rotation is taken away, good heat dissipation effect changes
It has been apt to the working environment of bearing, has improved the service life of bearing.
Detailed description of the invention
Fig. 1 is the schematic diagram of existing automobile right driving axle medial support structures.
Fig. 2 is structural schematic diagram of the invention.
Fig. 3 is the local direction view of the bearing spider in the present invention
Fig. 4 is the axial view of the second dustproof cover in the present invention.
Specific embodiment
It elaborates with reference to the accompanying drawing to the present invention.
Automobile right driving axle medial support structures as shown in Figure 2, Figure 3, Figure 4, including bearing 5, bearing snap spring 4, first
Dustproof cover 3, the bearing spider 2 of the second dustproof cover 6 and fixed installation on the engine, drive shaft shaft 1 are supported on by bearing 5
In the shaft pilot hole 21 of bearing spider 2, and by 4 axial limiting of bearing snap spring, the hole wall of shaft pilot hole 21 offers eight
Item is identical and along the circumferential direction evenly arranged ventilation groove 22, the length of every ventilation groove 22 and shaft pilot hole 21
Equal length（I.e. every ventilation groove 22 all extends along the axis direction of shaft pilot hole 21, the both ends for groove 22 of divulging information and axis
The both ends of bar pilot hole 21 flush）, the first dustproof cover 3 is located at the side of bearing 5, and in shaft pilot hole 21, first is anti-
3 sets of dirt lid on drive shaft shaft 1, can rotate under the drive of drive shaft shaft 1, and the second dustproof cover 6 is located at the another of bearing 5
Side, and except shaft pilot hole 2, the second 6 sets of dustproof cover, can be under the drive of drive shaft shaft 1 on drive shaft shaft 1
Rotation, the second dustproof cover 6 are in flaabellum shape, are along the circumferential direction rearranged for 120 ° of uniform pitch by 11 identical blades 61
（The angle of the axis of i.e. each blade plane and drive shaft shaft 1 is 120 °）, axis of adjacent two blade 61 in drive shaft shaft 1
Line partly overlaps on direction（I.e. in terms of the axis direction of drive shaft shaft 1, gapless between each adjacent blades）.
When drive shaft shaft 1 rotates, the first dustproof cover 3 and the second dustproof cover 6 follow drive shaft shaft 1 to rotate together, the
One dustproof cover 3, the second dustproof cover 6 play dustproof effect, prevent dust and muddy water from entering bearing 5, and the second dustproof cover 6 is rotating
When, 61 high speed rotation of blade plays the role of fan, and air-flow flows under the action of blade 61 along ventilation groove 22, air-flow
During being flowed along ventilation groove 22, it will be distributed and the heat band that generation due to is assembled when rotating of bearing 5 because of exhaust pipe
It walks, reduces the temperature of the temperature and bearing 5 in shaft pilot hole 21, improve the working environment of bearing 5, to promote bearing 5
Service life.
