Abstract
The utility model discloses a kind of antifriction washers, including antifriction washer body, the antifriction washer body is made of basis material and the anti-friction coating being overlying on outside basis material, the basis material by circular ring shape end face be surrounded on circular ring shape end face outer ring edge and perpendicular to circular ring shape end face setting fixed ring form, circular through hole is equipped at the circular ring shape end face center, the fixed ring is equipped with several fixed salient points, and the antifriction washer body is fixedly connected with press fitting with clutch can angle head cylindrical into an entirety.The utility model has the following beneficial effects: (1) surface smooth even friction reducing effect is good；(2) adhesive force and wearability are good；(3) long service life.
Description
Technical field
The utility model relates to a kind of auto parts, more particularly, to a kind of antifriction washer.
Background technique
When vehicle start, drive shaft fixing end end face and wheel hub binding face have an opposite movement, and two end faces compared with
Be it is smooth, be easy to produce stick-slip, cause start to walk abnormal sound.Stick-slip is generated in order to eliminate two metal surfaces, is being driven
Moving axis clutch can applies a kind of anti-friction agent on end face.
Anti-friction agent is manually smeared after part is processed as finished product in the prior art, is had the disadvantage that:
1) anti-friction agent is liquid state, and coating layer thickness is difficult to uniformly after smearing, and adhesive force is small, in assembly and handling process easily
It falls off；
2) part needs just to can enter carry out next process, production section after anti-friction agent solidifies after smearing anti-friction agent
It claps slower；
3) in vehicle use process, since anti-friction agent is easy to wear, clutch can end face and the friction of wheel hub end face can wear away portion
Divide anti-friction agent, anti-friction agent is caused to fail.
Utility model content
The utility model be in order to overcome in the prior art anti-friction agent it is in uneven thickness, can not hot setting, adhesive force and
The poor problem of wearability, provides a kind of surface smooth even, adhesive force and a kind of good antifriction washer of wearability.
To achieve the goals above, the utility model uses following technical scheme:
A kind of antifriction washer, including antifriction washer body, the antifriction washer body is by basis material and is overlying on base
The anti-friction coating of body material outer is constituted, and the basis material is by circular ring shape end face and is surrounded on circular ring shape end face outer ring edge
And formed perpendicular to the fixed ring of circular ring shape end face setting, circular through hole is equipped at the circular ring shape end face center, it is described
Fixed ring is equipped with several fixed salient points, and the antifriction washer body is fixedly connected with press fitting with clutch can angle head cylindrical into one
It is whole.
Pass through the antifriction on antifriction washer instead of anti-friction agent in the prior art using antifriction washer in the utility model
Coating can effectively reduce the frictional force of drive shaft fixing end end face Yu wheel hub binding face, while the anti-friction coating passes through height
Temperature solidification is attached on basis material, so that its adhesive force and wearability are excellent in, enhances its reliability used.Pass through
Fixed salient point enables to antifriction washer to can be good at being fixed on clutch can end face, anti-friction pad circle can be made to will not fall off,
It will not be produced relative sliding with clutch can.
Preferably, the number of the fixed salient point is 2 or 3.2 or 3 fixed salient points can guarantee to subtract
The washer that rubs can be good at being fixed on clutch can end face, will not produce relative sliding with clutch can.
Preferably, the fixed salient point is uniformly distributed on the circumference of fixed ring.It is uniformly distributed in the circle of fixed ring
It enables to power suffered by antifriction washer respectively to identical on week, guarantees its stability fixed.
Preferably, the anti-friction coating is polytetrafluoroethylene (PTFE) anti-friction coating.Polytetrafluoroethylene (PTFE) has self-lubricating property,
It can be good at playing the effect for reducing frictional force.
Preferably, the polytetrafluoroethylene (PTFE) anti-friction coating with a thickness of 0.5-1.5mm.With a thickness of 0.5-1.5mm's
Polytetrafluoroethylene (PTFE) has certain thickness, can make it have longer service life in the case where meeting lubricity.
Preferably, using interference fit connection between the antifriction washer body and clutch can.Using interference fit
Connection can satisfy the fixed firmness of antifriction washer.
Preferably, end face of the antifriction washer body far from clutch can is the smooth plane in surface.
Therefore, the utility model has the following beneficial effects: (1) surface smooth even friction reducing effect is good；(2) adhesive force and
Wearability is good；(3) long service life.

Specific embodiment
The utility model is further described with specific embodiment with reference to the accompanying drawing.
In embodiment as shown in Figs. 1-5, a kind of antifriction washer, including antifriction washer body 1, the antifriction washer sheet
Body 1 by basis material 12 and be overlying on 12 outside thickness of basis material be 0.5-1.5mm polytetrafluoroethylene (PTFE) anti-friction coating 13 constitute,
The basis material 12 is by circular ring shape end face 14 and is surrounded on 14 outer ring edge of circular ring shape end face and perpendicular to circular ring shape end face
The fixed ring 15 of 14 settings forms, and circular through hole 11 is equipped at 14 center of circular ring shape end face, and the fixed ring 15 is set
There are fixed salient point 16 on 2 or 3 circumference for being uniformly distributed in fixed ring 15, the antifriction washer body 1 and 2 end of clutch can
For face outer circle using interference fit connection press fitting at an entirety, the end face far from clutch can 2 is the smooth plane in surface.
