Abstract

The utility model discloses a plane gasket has ring piece body structure, and the upper and lower terminal surface of ring lamellar body is the plane, its characterized in that: the ring lamellar body is formed by cup jointing fixed interior ring sum outer loop together, and the outer loop is the punching press pallet, and the inner ring is the powder metallurgy board. The utility model discloses a composite construction, can improve the greasy property of gasket contact surface, reduce the friction of gasket contact surface, the use as automotive differential differential side gear thrust gasket is particularly suitable for.

Description

Flat pad

Technical field

This utility model relates to the improvement of a kind of flat pad.

Background technology

In automobile differential, the thrust washer, diff. gear of application is a kind of flat pad, this flat pad is installed between the housing and axle shaft gear of differential mechanism and is played the thrust function preventing axle shaft gear from retreating, due to axle shaft gear high-speed rotation when differential mechanism works, so must assure that the both sides contact surface of this flat pad has good lubrication.

Summary of the invention

For the deficiencies in the prior art, the purpose of this utility model is to be in that providing a kind of adopts composite construction, can improve the greasy property of pad contacting surface, reduce the flat pad of the friction of pad contacting surface.

This utility model is implemented by the following technical programs:

Flat pad, has annulus lamellar body structure, and the upper and lower end face of annulus lamellar body is plane, it is characterised in that: annulus lamellar body is made up of the internal ring being fixed by socket together and outer shroud, and outer shroud is stamped sheet metal, and internal ring is powder metallurgy plate.

Inner ring surface is provided with the first open-work, and external annular surface is provided with the second open-work, and between adjacent first, second open-work, the oil groove by offering in annulus lamellar body upper and lower end face communicates.

The flat pad that this utility model provides, have employed composite construction, and outer shroud is stamped sheet metal, internal ring is powder metallurgy plate, powder metallurgy plate can improve the greasy property of pad contacting surface, reduces the friction of pad contacting surface, and stamped sheet metal then provides enough intensity for pad and ensures.Further, the contact surface being arranged on whole pad of open-work and oil groove forms a kind of unimpeded grease channel, the effect of the friction also can play the greasy property improving pad contacting surface, reducing pad contacting surface.

For improving the connection reliability between inner and outer ring, have employed techniques below scheme: the cylindrical of internal ring is provided with fixture block, the endoporus of outer shroud is provided with draw-in groove, and fixture block is fixed in draw-in groove.

Accompanying drawing explanation

This utility model has drawings described below:

Fig. 1 is structural representation of the present utility model,

Fig. 2 is the axial sectional structure chart of Fig. 1.

Detailed description of the invention

As it can be seen, flat pad of the present utility model, having annulus lamellar body structure, the upper and lower end face of annulus lamellar body is plane, and annulus lamellar body is made up of the internal ring 2 being fixed by socket together and outer shroud 1, and outer shroud 1 is stamped sheet metal, and internal ring 2 is powder metallurgy plate.The cylindrical of internal ring 2 is provided with fixture block 4, and the endoporus of outer shroud 1 is provided with draw-in groove 3, and fixture block 4 is fixed in draw-in groove 3.Internal ring 2 surface is provided with the first open-work 5, and outer shroud 1 surface is provided with the second open-work 7, and between adjacent first, second open-work, the oil groove 6 by offering in annulus lamellar body upper and lower end face communicates.
