Abstract
The utility model relates to a brake of automotive vehicles. The utility model has the technical proposal that a brake drum fixed on a wheel hub is rotated together with a carriage wheel, and a plurality of triangle braking shoes are strung together by two arc shoe rods and arranged in a circular ring of the brake drum. The connection part of the two shoe rods is connected with a rest pin and a friction disk is riveted at the bottom margin of each shoe. A return spring is arranged inside each shoe and is linked with the other connection of the two shoe rods. A cam clamped between two transition blocks is connected with a brake foot-plate through a connecting rod. The stepping down or up of the foot-plate can control the rotation of the cam. The utility model has the advantages of simple structure, low cost, high reliability, etc.
Description
The utility model relates to a kind of motor vehicle brake.
The drg of automobile all is a pneumatic brake system at present, complex structure, and poor reliability, and involve great expense.Because complex structure is given and is made and keep in repair and all make troubles.
The purpose of this utility model is: a kind of simple in structure, cheap, motor vehicle brake that reliability is high is provided.
Below in conjunction with description of drawings the utility model.
Accompanying drawing is a structural representation of the present utility model.
Brake drum 4 is fixed on the wheel hub, rotate together with wheel, several triangle brake shoes 9 by two arc hoof piece bars, 5 strings together, be placed in the annulus of brake drum, the junction of two hoof piece bars is on fulcrum post 8, in the riveting of the base of each hoof piece friction plate 7 is arranged, the in-built return spring 6 of each hoof piece is littler near the hoof piece gradient of fulcrum post, the elastic force of return spring is also littler, another junction of two hoof piece bars, between 11 two transition block of two transition block of ining succession, the return spring 10 of ining succession, between two transition block, clip cam 3, cam is connected with braking footrest 1 by connecting rod 2, and stepping on and lifting of pedal can be controlled the cam rotation. Operation principle is: at ordinary times, the hoof piece is on cramp bar, and friction plate and the wheel hub of hoof piece are gapped, and wheel can rotate freely, make reducing speed of motor vehicle, the driver can step on brake pedal gently, and cam is rotated, cam extruding hoof piece, hoof piece near banking pin is squeezed out with the brake drum friction, frictional force can be decomposed into a component that points to fulcrum post, and this component increases the hoof piece pressure of back, braking effect occurred. When continuing to step on brake pedal, cam angle increases, and all hoof pieces all work, and produce very big braking moment, and wheel is stall immediately. Decontrol pedal, under the effect of return spring, the brake shoe braking moment that resets is rapidly eliminated.
The utility model compared with prior art, it has simple in structure, cheap, high reliability.
Claims (1)
