Abstract
The utility model relates to friction plates and particularly relates to a friction plate for a heavy-duty trailer truck. The friction plate is mainly used for solving the technical problems that when a friction plate is applied to a transmission of the heavy-duty trailer 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 left half friction plate (1) and a right half friction plate (2) and is characterized in that both the left half friction plate (1) and the right half friction plate (2) are arc-shaped, a plurality of rivet mounting holes (3) are formed in the left half friction plate (1) and the right half friction plate (2), and the thickness of the inner end of each of the left half friction plate and the right half friction plate is greater than that of the outer end of each of the left half friction plate and the right half friction plate.
Description
Technical field
The utility model relates to a kind of friction plate, especially relates to a kind of heavy type and pulls the lorry 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.But this friction plate is used in heavy type when pulling in the speed changer of lorry, has 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 phenomenon of falling apart can occur.
The model utility content
The utility model provides a kind of heavy type and pulls the lorry friction plate, it mainly is to solve the existing in prior technology friction plate to be used in heavy type when pulling in the speed changer of lorry, 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:
Heavy type of the present utility model is pulled the lorry friction plate, comprise left half friction plate and right half friction plate, a described left side half friction plate and right half friction plate are arc all, have a plurality of rivet mounting holes on it, and the thickness of left half friction plate, right half friction plate the inner is greater than the thickness of its outer end.A left side half friction plate and right half friction plate are made by the waste material of friction plate, so manufacture cost is lower, and technology is comparatively simple, also comparatively environmental protection.The thickness an of left side half friction plate, right half friction plate the inner is thicker, makes that the intensity of friction plate is stronger, and wear resistance is better.
As preferably, the two ends of a described left side half friction plate and right half friction plate upper surface are respectively equipped with chamfering.
As preferably, the both sides of a described left side half friction plate, right half friction plate respectively are provided with 2 row's rivet mounting holes, and every row's rivet mounting hole is 4.Uniform rivet mounting hole on a left side half friction plate, right half friction plate like this can be so that be installed to friction plate on the brake shoe securely.
Therefore, the utility model is made up of a left side half friction plate and right half friction plate, 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 plan structure schematic representation of Fig. 1.
Component, position and numbering among the figure: left half friction plate 1, right half friction plate 2, rivet mounting hole 3, chamfering 4.
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 heavy type of this example is pulled the lorry friction plate, as Fig. 1, Fig. 2, comprise left half friction plate 1 and right half friction plate 2, a left side half friction plate and right half friction plate all are arc, have a plurality of rivet mounting holes 3 on it, the thickness of left half friction plate, right half friction plate the inner is greater than the thickness of its outer end.The two ends of a left side half friction plate and right half friction plate upper surface are respectively equipped with chamfering 4.The both sides of a left side half friction plate, right half friction plate (2) respectively are provided with 2 row's rivet mounting holes 3, and every row's rivet mounting hole is 4.
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.
