Abstract
This utility model relates to a kind of in-between car power transmission shaft intermediate support assembly, including expanded letter bearing, double-deck anti-dust seal, rubber pad ring, bearing block, snap ring and middle bearing support, described expanded letter bearing bearing block coordinates, snap ring limits moving axially of expanded letter bearing, rubber pad ring vulcanizes on bearing block, middle bearing support is arranged on the outside of rubber pad ring, and double-deck anti-dust seal is arranged between outer ring and the inner ring of expanded letter bearing and the both sides of rolling element.Solve in adverse circumstances, the problem of the inefficacy that oil sealing in intermediate support and bearing are easily subject to dust and mud invasion causes.
Description
Technical field
This utility model belongs to auto parts machinery field, is specifically related to a kind of in-between car power transmission shaft intermediate support assembly.
Background technology
On long wheelbase automobile, in order to improve power transmission shaft critical speed, it is to avoid resonate and consider in car load general layout
Needs, often by power transmission shaft segmentation.Intermediate support is typically mounted in frame cross or on body understructure, to compensate power transmission shaft
Axially and the alignment error of angle direction, due to the play of flexibly mounted electromotor and vehicle frame etc. and in vehicle travel process
Displacement caused by deformation.The most widely used caoutchouc elasticity intermediate support is primarily subjected to power transmission shaft because of uneven, eccentric etc.
The radial force that factor causes, and the radial force caused by the additional bending moment on universal joint.Work under some relatively adverse circumstances
Automobile in, oil sealing and bearing in intermediate support are easily subject to dust, slurry compounding, cause inefficacy.
Summary of the invention
This utility model provides a kind of in-between car power transmission shaft intermediate support assembly, solves in adverse circumstances, middle
The problem of the inefficacy that oil sealing in holding and bearing are easily subject to dust and mud invasion causes.
The purpose of this utility model is achieved through the following technical solutions:
A kind of in-between car power transmission shaft intermediate support assembly, including expanded letter bearing 4, double-deck anti-dust seal 7, rubber pad ring 1, axle
Bearing 2, snap ring 3 and middle bearing support 5, described expanded letter bearing 4 bearing block 2 coordinates, and snap ring 3 limits the axle of expanded letter bearing 4
To movement, rubber pad ring 1 vulcanizes on bearing block 2, and middle bearing support 5 is arranged on the outside of rubber pad ring 1, double-deck dust laying oil
Envelope 7 is arranged between the outer ring 6 of expanded letter bearing 4 and inner ring 7 and the both sides of rolling element 9.
The beneficial effects of the utility model:
The inside that double-deck anti-dust seal is integrated in expanded letter bearing of the present utility model, is effectively increased intermediate support opposing
Extraneous dust, slurry compounding and prevent the excessive ability of grease.Honeycomb style rubber can reduce power transmission shaft frequency of vibration, keeps away
Exempt from resonance.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model；
Fig. 2 is A-A sectional view of the present utility model.
Detailed description of the invention
The utility model is described in more detail below in conjunction with the accompanying drawings.
As illustrated in fig. 1 and 2, this utility model provides a kind of in-between car power transmission shaft intermediate support assembly, including expanded letter bearing
4, double-deck anti-dust seal 7, rubber pad ring 1, bearing block 2, snap ring 3 and middle bearing support 5, described expanded letter bearing 4 bearing block 2
Coordinating, snap ring 3 limits moving axially of expanded letter bearing 4, and rubber pad ring 1 vulcanizes on bearing block 2, and middle bearing support 5 is arranged
In the outside of rubber pad ring 1, double-deck anti-dust seal 7 is arranged between the outer ring 6 of expanded letter bearing 4 and inner ring 7 two with rolling element 9
Side.This organization plan is effectively increased the intermediate support extraneous dust of opposing, slurry compounding and prevents the excessive ability of grease.
