Abstract
The utility model discloses a brake which comprises a brake bottom plate. A friction piece, a left brake shoe and a right brake shoe are fixedly connected with the brake bottom plate, the left brake shoe and the right brake shoe are symmetrically arranged, a cam shaft is arranged between the upper end of the left brake shoe and the upper end of the right brake shoe, flat plates are respectively arranged on the upper end portion of the left brake shoe and the upper end portion of the right brake shoe, one side where the flat plates are contacted with the cam shaft is a plane, and the lower end portion of the left brake shoe and the lower end portion of the right brake shoe are connected with the brake bottom plate through an eccentric shaft and are locked through an opening pin and a locking nut. The brake has the advantages that contour lines of two sides where the flat type cam shaft, namely the cam shaft, is contacted with the left brake shoe and the right brake shoe are straight lines, one side where the flat plate is contacted with the cam shaft is the plane, aims such as big output power amount and easily-automatic reset are achieved, simultaneously, a gap caused by abrasion of the friction piece is compensated through the eccentric shaft, and normal use of a vehicle is ensured.
Description
Technical field
The utility model belongs to the automobile brake technical field, particularly a kind of break.
Background technique
Break is to have to make moving element (or movable machinery) slow down, stop or keeping the device of the functions such as halted state.
It is large that the automobile on straight highway of travelling generally need to be exported strength, the easy break of the performance such as self-return, but the output strength of most break is little, is not easy self-return, can not adapt to travel in the road conditions demand of automobile preferably.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of output strength large, easily the break of self-return.
for solving the problems of the technologies described above, a kind of break that the utility model provides, it comprises brake backing plate, the left brake shoe and the right braking hoof that are fixedly connected with friction plate on described brake backing plate and are arranged symmetrically with, be provided with camshaft between the upper end of described left brake shoe and right braking hoof, described camshaft is arranged on brake backing plate, the upper end of described left brake shoe and right braking hoof is by being in the returning pull-spring tension of extended state, the upper end portion of described left brake shoe and right braking hoof is provided with respectively flat board, the side that described flat board contacts with camshaft is the plane, described left brake shoe is connected the underpart and is connected with brake backing plate by eccentric shaft with right braking hoof, and lock with cotter pin and locking nut, described cotter pin is with left, right braking hoof is provided with connecting plate between the underpart.After brake bush may wear to certain limit, the capable of regulating eccentric shaft satisfied brake clearance, thereby satisfied the vehicle normal operating condition.
As preferably, the profile line of the both sides of described camshaft and left brake shoe and right braking hoof touching position is straight line, and a dull and stereotyped side that contacts with cam is the plane, and assurance has larger ouput force, can realize the performances such as easy self-return.
As preferably, described flat board and left and right brake shoe are one-body molded.Convenient processing.
As preferably, the width of described friction plate is 80mm.
After adopting above structure, a kind of break of the present utility model compared with prior art, have the following advantages: adopting flat camshaft is that the profile line of the both sides of camshaft and left brake shoe and right braking hoof touching position is straight line, and a dull and stereotyped side that contacts with cam is the plane, realize that output strength is large, the easy performance such as self-return compensate the gap that the wearing and tearing due to friction plate cause, the normal use of assurance vehicle by eccentric shaft simultaneously.
