Problems solved by technology

Among these products, some of the drum brakes have a self-adjusting function through the automatic adjustment arm, but after a period of use, the adjustment arm will appear heat, brake failure, loud noise, etc.
At the same time, the processing accuracy of the automatic adjustment arm is also very high, making its price much higher than that of the ordinary adjustment arm, and after the brake adjustment arm is installed, the accuracy of all parts of the brake needs to be improved, which greatly increases the cost of the brake
[0003] On the other hand, since the excessive clearance of the drum brake is not entirely caused by the wear of the

Abstract

This invention relates to brake gap adjusting double chuck clamp gas pressed brake device, which comprises the following scheme: One brake clamp and brake rack connected through slide pair; the inner and outer brake underlay are paralleled down the brake clamp with certain distance and rely against the brake rack through spring on the pressure board; the brake clamp top has brake gas chamber with bar connected to the stick, wherein, the said brake clamp inside chamber has double chuck gap adjusting structure connected to the down cover board to the brake clamp; the other end of the bar has semi-circle block connected to brake clamp through semi-circle block.

Description

technical field [0001] The invention relates to automobile brakes, more specifically, to a double-push disc double-adjustment caliper type pneumatic brake device with self-adjusting brake clearance. Background technique [0002] At present, drum brakes are commonly used on trucks, buses and trailers in my country. The biggest disadvantage is that the brake clearance is manually adjusted after the friction lining is worn. After the car has been running for a period of time, the brake gap increases and the brake becomes weak, and the driver then manually adjusts to reduce the gap. However, how much the gap should be adjusted requires the driver to have a higher technical level and driving experience. If it cannot be adjusted in time, there will be a potential safety hazard. Brake clearance adjustment is a key item in automobile driving, maintenance and repair operations. In the past two decades, in order to reduce the workload of maintenance, automatic adjustment devices for ...
