Abstract
The utility model relates to friction plates and particularly relates to a friction plate for a medium-duty truck. The friction plate is mainly used for solving the technical problems that when a friction plate is applied to a transmission of the medium-duty truck, the friction plate is subjected to certain attrition, a friction material layer loses effectiveness due to loss after the friction plate is used for a long time, then, the friction moment is reduced, the power transmission of a motor vehicle is affected, even, the phenomenon of falling apart occurs, and the like in the prior art. The friction plate comprises a friction plate body (1) and is characterized in that the friction plate body (1) is arc-shaped, a plurality of rivet mounting holes (2) are formed in the friction plate body (1), chamfers (3) are respectively formed at two ends of the upper surface of the friction plate body, and the arc angle alpha of the friction plate body is 50-65 degrees.
Description
Technical field
The utility model relates to a kind of friction plate, especially relates to a kind of medium truck friction plate.
Background technique
At present, friction plate is widely used in and is applied in the machinery, all needs friction plate to carry out clutch and braking as lathe, automobile, and existing friction plate mainly is made of sintering metal liner and composite material liner, and the sintering metal liner is the ring laminar body.Chinese patent discloses a kind of clutch friction plate (notice of authorization number: CN 201382108Y), its by the steel core plate and be arranged at the steel core plate on, two lip-deep friction material dough sheets are formed down, uniform several to fixed hole on the steel core plate, the friction material dough sheet is provided with the riveted holes relative with fixed hole, the friction material dough sheet is riveted on the steel core plate by riveted holes and fixed hole, on the friction material dough sheet, lower surface is provided with oil clearance, oil clearance is the trellis oil clearance, by rotate clockwise that direction tilts and and the steel core plate forms between radially angle the gap and along be rotated counterclockwise the direction inclination and and the steel core plate gap that forms angle between radially interlace and form, angle is 45～60 °, and the friction material dough sheet is asbestos-free friction material or powder metallurgy sintered material.But this friction material dough sheet heat load is low, and wear rate is higher, and working life is shorter.When but this friction plate is used in the speed changer of medium truck, have certain attrition, after service time was long, friction material layer lost efficacy through loss, caused friction torque to reduce, thereby influenced the Motor Vehicle transmission of power, even the phenomenon of falling apart can occur.
The model utility content
The utility model provides a kind of medium truck friction plate, it mainly is when solving in the speed changer that the existing in prior technology friction plate is used in medium truck, have certain attrition, after service time is long, friction material layer lost efficacy through loss, cause friction torque to reduce, thereby influence the Motor Vehicle transmission of power, even the technical problem of the phenomenon etc. that can occur falling apart.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Medium truck friction plate of the present utility model comprises the friction plate body, and described friction plate body is arc, has a plurality of rivet mounting holes on it, and the two ends of friction plate body upper surface are respectively equipped with chamfering, and the arc round angle α of friction plate body is 50-65 o.The friction plate body is made by the waste material of friction plate, so manufacture cost is lower, and technology is comparatively simple, also comparatively environmental protection.
As preferably, two row's rivet mounting holes of described friction plate body both sides all are 4, and two row's rivet mounting holes at friction plate body middle part all are 2.Uniform rivet mounting hole on the friction plate body like this can be so that be installed to friction plate on the brake shoe securely.
Therefore, the utility model is made up of the friction plate body of arc, and material adopts the waste material of friction plate to make, and therefore the cost of making is lower, and manufacturing process is comparatively simple, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is side structure schematic representation of Fig. 1.
Component, position and numbering among the figure: friction plate body 1, rivet mounting hole 2, chamfering 3.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the medium truck friction plate that this is routine as Fig. 1, Fig. 2, comprises friction plate body 1, the friction plate body is arc, have a plurality of rivet mounting holes 2 on it, the two ends of friction plate body upper surface are respectively equipped with chamfering 3, and the arc round angle α of friction plate body is 59 o.Two row's rivet mounting holes 2 of friction plate body both sides all are 4, and two row's rivet mounting holes at friction plate body middle part all are 2.
During use, friction plate is encased in the gearbox skidding hoof assembly of heavy goods vehicle and gets final product.
The above only is specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the claim of the present utility model.
Claims (2)
1. medium truck friction plate, comprise friction plate body (1), it is characterized in that described friction plate body (1) is arc, have a plurality of rivet mounting holes (2) on it, the two ends of friction plate body upper surface are respectively equipped with chamfering (3), and the arc round angle α of friction plate body is 50-65 o.
2. medium truck friction plate according to claim 1 is characterized in that two row's rivet mounting holes (2) of described friction plate body (1) both sides all are 4, and two row's rivet mounting holes (2) at friction plate body middle part all are 2.
