Abstract

The clutch plate of the utility model provides a structure that composite friction material layers are coated on the upper and lower surface and the side end face of the circumference of the clutch metal substrate by the means of hot compacting; through holes are uniformly distributed on the metal substrate; the upper and lower surface of the clutch metal substrate is a planar construction; the through holes are distributed in a radial direction or an interleaving direction; the inner ring portion is provided with a circular port and the outer ring portion is a semi-circle port. Compared with the conventional clutch plate, the utility model has the advantages of simple structure, good firmness, high twisting resistance, high intensity and good using effect.

Description

Clutch plate

Technical field

The utility model relates to a kind of automobile-use accessory, especially relates to a kind of once hot pressing clutch plate.

Background technique

Automobile clutch sheet in the market was for three stacked adding and forms, and in the middle of promptly by upper and lower two-layer nonmetallic composite wearing piece metal substrate being installed in, by rivet it being combined constitutes, and its structure as shown in Figure 1.(1` is the center land among Fig. 1, and 2` is a metal substrate, and 3` is compound friction material layer.) this clutch plate exists following defective; 1 is made up of three kinds of parts, assembles up more time-consumingly, and integrating error are bigger; The product that assembles out also needs processing separately, the cost of production height, and time-consuming, the product reject rate is higher.2 in use, because wearing piece is worked under high-speed and high-temperature, have certain attrition, long compound friction sheet material of time one will attenuation, make the rivet projection, so directly with adjacent counterpart friction, cause that friction reduces, the obvious problem of increasing of noise, thereby influence the Motor Vehicle transmission of power, base is to the phenomenon of falling apart occurring.3 because this clutch plate is to connect with rivet, and rivet itself takies the thickness of certain nonmetal compound wearing piece, makes wearing piece reduce availability, shortens product working life, has caused meaningless waste.Based on the problems referred to above, some Motor Vehicle clutch-plate has changed the once hot pressing manufacture method into, owing to adopt no rivet arrangement, has improved the availability of this product, has reduced the user cost of Motor Vehicle, has reduced the number of times of changing the friction plate on the clutch.The clutch plate of above-mentioned once hot pressing exists the complicated and high problem of cost of manufacturing process, its reason is in order to make nonmetal abrasives layer become an integral body with the substrate strong bonded, in the shape that is processed with complexity in shape of substrate, as the base surface shape of groove or corrugation shape.

Summary of the invention

Clutch plate described in the utility model can solve problems such as the complicated and cost height of processing technology that the once hot pressing clutch plate exists.

Clutch plate described in the utility model, its structure comprises: upper and lower surface and circumference end face at the clutch metal substrate are coated with compound friction material layer by hot-forming mode, on metal substrate, be evenly equipped with open-work, it is characterized in that: the upper and lower surface of metal substrate is plane structure, described open-work is by radiation direction or be interspersed, annular inner portion is a circular port, and outer ring portion is a semi-circular hole.

Aforesaid clutch plate is positioned on the land of substrate center and has spline, has a spline steel bushing to place in this spline, is nested with and is fixedly connected with axle in the spline steel bushing.

Advantage and positive effects such as the utility model is compared with traditional clutch plate, and it is more simple to have structure, and robustness is good, and torsional rotation force and intensity height and using effect are good.

Description of drawings

Fig. 1 is the structural representation of the clutch plate of prior art;

Fig. 2 is the utility model plan view;

Fig. 3 is the plan view of metal substrate in the utility model.

Embodiment

Concrete structure of the present utility model can be referring to accompanying drawing, shown in Fig. 2,3, this clutch plate comprises the annular metal substrate 2 that is provided with center land 1, upper and lower surface and circumferential end surfaces at metal substrate 2 are coated with compound friction material layer 3, cladding process is at next an ancient unit of weight equal to 20 or 24 *taels of silver thermoforming of high-temperature and high-pressure conditions with mould, described metal substrate 2 is plane structure, the open-work 4 that evenly is processed with radially on it or interlaces and arrange for upper and lower surface.The open-work 4 that is positioned at inboard loop section is for circular, and outer ring partly is semicircle.

Be nested with the spline steel bushing that is fixed with respective shapes in the spline of center land 1, axle is nested with is fixed in (not shown) in the spline steel bushing.

This device is guaranteeing with the most succinct design, to have reduced the generation processing cost effectively under the good prerequisite of compound friction material monolithic, robustness.This device is applicable to the Motor Vehicle of various power.
