Description
Technical field
The utility model belongs to the technical field of brake device for car, particularly relates to a kind of brake shoe of chain type break of truck.
Background technique
Though existing automobile drum type brake has become perfect through repeatedly improving its braking ability, but brake or the emergency braking in heavier or lower long slope situation at load, often braking retardation, stopping distance is elongated, and after braking, return does not thoroughly cause to drag and stops, become vehicle travel in the major safety risks such as oil consumption increase, and the surface of contact of Cam braking is little, stress is large, and the amount of strutting is little, and unfailing performance is low.In order to solve above-mentioned Problems existing, be currently suggested a kind of chain type break of truck, adopt brake shoe and Brake drum to be formed and hold braking effect tightly, eliminate traditional brake cam, greatly reduce period of braking, shorten braking distance, thus reduce the hidden danger of road traffic accident, therefore, it is very necessary for proposing a kind of brake shoe adapted with chain type break.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of brake shoe being applicable to the chain type break of truck.
The utility model solves the technological scheme that its technical problem adopts: a kind of brake shoe of chain type break of truck, it is characterized in that, comprise left hoof and right hoof, described left hoof comprises left shoe plate and brake strip, described right hoof comprises right shoe plate and brake strip, left and right shoe plate is the tile fragment structure of semicircular arc, and described brake strip is arc plate, and brake strip is installed respectively on the inner peripheral surface of left and right shoe plate; The opening of left and right shoe plate is oppositely arranged, and one end of left and right shoe plate is all had hinging hole and is hinged by shoe shaft and shoe plate axis hole, and the termination of the left and right shoe plate the other end is installed on coupling shaft, and the termination, outside of described coupling shaft is connected with the termination of return spring.
By such scheme, inwardly have " U " type groove in the middle part of the termination of the described left and right shoe plate the other end, on the biside plate of described " U " type groove, symmetry has through hole, is installed on coupling shaft in described through hole, the termination, outside of described coupling shaft is provided with locating stud, and described locating stud is connected with the termination of return spring.
By such scheme, the inner peripheral surface of described left and right shoe plate is installed on respectively two pieces of described brake strips.
The beneficial effects of the utility model are: the brake shoe 1, providing a kind of chain type break of truck, brake shoe and Brake drum form outer support braking effect, cancel traditional braking drum, avoid, because outer tension force causes brake drum to break, occurring traffic accident and personal injury; 2, the utility model is reasonable in design, and stress surface of contact is large, and stress is little, and reliability is high, and the amount of strutting is large, and amount of maintenance reduces, long service life.
Accompanying drawing explanation
Fig. 1 is the axonometric drawing of the right shoe plate of the utility model embodiment.
Fig. 2 is the front view of the right shoe plate of the utility model embodiment.

Wherein: 1, left shoe plate, 2, right shoe plate, 3, hinging hole, 4, return spring, 5, brake strip, 6, through hole, 7, coupling shaft, 8, " U " type groove.
Embodiment
For understanding the utility model better, below in conjunction with drawings and Examples, the utility model will be further described.
As Figure 1-3, a kind of brake shoe of chain type break of truck, comprise left hoof and right hoof, left hoof comprises left shoe plate 1 and brake strip 5, right hoof comprises right shoe plate 2 and brake strip 5, left and right shoe plate is the tile fragment structure of semicircular arc, and brake strip is arc plate, and brake strip is installed respectively on the inner peripheral surface of left and right shoe plate; The opening of left and right shoe plate is oppositely arranged, one end of left and right shoe plate all has hinging hole 3, be hinged by the shoe plate axis hole of shoe shaft and braking bottom board, " U " type groove 8 is inwardly had in the middle part of the termination of the left and right shoe plate the other end, on the biside plate of " U " type groove, symmetry has through hole 6, coupling shaft 7 is installed in through hole, the termination, outside of coupling shaft is provided with locating stud, locating stud is connected with the termination of return spring 4, by coupling shaft and linking mechanism phase configuration, what realize brake shoe and Brake drum holds braking tightly.
The inner peripheral surface of left and right shoe plate is installed on respectively two pieces of brake strips 5, during brake, the outer circumferential face of brake strip and the inner peripheral surface of left and right shoe plate fit, and the inner peripheral surface of brake strip and the outer circumferential face of Brake drum fit.
