Abstract
The utility model designs a friction plate for a brake shoe of a truck. The friction plate comprises an arc block, the outer peripheral face of the arc block serves as a mounting face while the inner peripheral face of the arc block serves as a braking friction face, the mounting face is fittingly connected with the inner circumferential face of a shoe plate of the brake shoe, the braking friction face fits the outer circumferential face of a brake wheel, and connection holes are formed at intervals in the arc block and penetrate through the inner and outer peripheral faces. The friction plate for the brake shoe of the truck has the advantages that 1, the friction plate for the brake shoe of the truck is provided for peripheral locking type braking, the friction plate is in friction with the brake wheel to generate a braking force when the brake shoe locks the periphery of the brake wheel for braking, so that the truck can be braked timely; 2, the friction plate is matched with the brake shoe to form a braking structure with the brake wheel locked peripherally, and consequently heat radiation of a braking system can be enhanced effectively to enable stability and reliability of braking performance.
Description
Technical field
The utility model belongs to the technical field of automotive axle braking, relates in particular to a kind of friction plate of trunk brake hoof.
Background technique
Automobile drum braking is simple in structure owing to having, braking torque is large, low cost of manufacture, the plurality of advantages such as easy to maintenance is still widely used on truck so far, but it easily causes the accident of brake failure often to have generation because braking produces high temperature, in order to solve the problem of above-mentioned existence, a kind of automobile wheel type braking vehicle bridge has been proposed at present, it adopts brake shoe and Brake drum to hold braking tightly, saved traditional liquid distribution, save brake drum, reduced the load of automobile, improved carrying capacity and radiating effect.Therefore it is very necessary, proposing a kind of friction plate adapting with brake shoe.
Summary of the invention
Technical problem to be solved in the utility model is to provide for the deficiency of above-mentioned prior art existence a kind of friction plate of trunk brake hoof.
The utility model solves the technological scheme that its technical problem adopts: comprise circular arc block, circular arc block outer circumferential face is attachment face, inner peripheral surface is brake area, the shoe plate inner peripheral surface of attachment face and brake shoe is matched, brake area and Brake drum outer circumferential face phase configuration, the spaced apart attachment hole that runs through inside and outside side face that is provided with on circular arc block.
Press such scheme, described circular arc block is made by abrasive rubber or high-abrasive material.
Press such scheme, the radian of described circular arc block is π/3 ~ 4 π/9(60 ° ~ 80 °).
Press such scheme, large outer little in described attachment hole, be riveted holes or screwing through hole.
Press such scheme, described attachment hole is along circumferentially laying 2 ~ 3 rows, and every row arranges 3 ~ 6.
Press such scheme, the axial width of described circular arc block is identical.
The beneficial effects of the utility model are: 1, a kind of friction plate that clamps the trunk brake hoof of braking for periphery is provided, when this friction plate is held the braking of Brake drum periphery tightly at brake shoe, utilize the friction of friction plate and Brake drum to produce braking force, make automobile brake in time or slow down; 2, form Brake drum periphery with brake shoe phase configuration and hold brake structure tightly, can effectively strengthen the heat radiation of braking system, make braking ability more reliable and stable.
Accompanying drawing explanation
Fig. 1 is the sectional arrangement drawing of friction plate and brake shoe.
Fig. 2 is the radial cross-section of friction plate.
Fig. 3 is the plane outspread drawing of friction plate.
Wherein: attachment face 1, rubbing surface 2, attachment hole 3, brake shoe 4, friction plate 5, Brake drum 6.
Embodiment
For understanding better the utility model, below in conjunction with drawings and Examples, the utility model will be further described.
As shown in Figure 1, the friction plate 5 of motor vehicle brake shoe is circular arc block, the radian of circular arc block is 4 π/9, the symmetrical central position that is installed on the inner peripheral surface of brake shoe 4 shoe plates of friction plate, two friction plates are respectively installed in left and right, and the outer circumferential face of circular arc block is attachment face 1, and inner peripheral surface is rubbing surface 2, the shoe plate inner peripheral surface of attachment face and brake shoe 4 joins, the outer circumferential face phase configuration of rubbing surface 2 and Brake drum 6.
As shown in Figure 2,3, the axial width of described circular arc block is identical, and circular arc block planar development is rectangle, has 6 attachment holes 3 on circular arc block, is fixed on the inner peripheral surface of brake shoe shoe plate by rivet.
Brake shoe 4 forms and holds braking tightly with Brake drum 6, and automobile is when braking state, and friction plate and Brake drum produce frictional force, and Brake drum is stopped operating.Stable, enough, controllable braking force that friction plate provides, is that automobile stops travelling in time, greatly reduces the hidden danger of road traffic accident.
Claims (6)
