Description
Technical field
The present invention relates to braking automobile hoof technical field more particularly to a kind of drum brakes hoof with protective performance.
Background technique
The general drum brake of drum brakes is made of rotating part, fixed part including shoe sole, wheel cylinder, brake
Vehicle shoe plate etc., drum brakes have a shape similar to the ironcasting of tambourine, referred to as brake drum, it is with tire fixation and rotates at the same speed.
Cost is relatively low for drum brakes, absolute brake Li Genggao, is more used in the rear-wheel of pony car.But its rate of wear compared with
Height, therefore overall cost is higher simultaneously, brake shoe refers to the active force by wheel cylinder or push rod and is pushed to outer expansion compacting
The accessory of braking action is heaved in braking, is installed on brake rim, is one of breaking piece crucial in brake system of car.Brake
Ungulate shape such as semilune, the semi-moon shaped brake shoe of two panels props up brake shoe just outer under the action of wheel cylinder when touching on the brake
The inner wall of brake drum of rubbing plays the role of slowing down or stopping；Traditional brake shoe is either slow in braking process
Slow application or emergency braking all can cause to wear to brake drum inner wall；By wear for a long time brake drum inner wall will appear it is recessed
It falls into；Braking effect can gradually decrease, and influence the traffic safety of people.
Summary of the invention
