Four-gear linkage brake clearance adjustment device

Abstract

The four-gear linkage brake clearance adjustment device combines the functions of the manual adjustment mechanism and the main adjustment mechanism. The main adjustment mechanism has the functions of manual clearance adjustment and active clearance adjustment, but it is not combined with the adjustment screw, and only plays the function of adjustment and overload prevention. , The driven adjustment mechanism is increased to two, the double push rod is combined with the slave adjustment mechanism, and the slave adjustment mechanism realizes the double push rod movement under the drive of the main adjustment mechanism. In this structure, the main adjustment mechanism is combined with the pressure arm to achieve the adjustment and anti-overload functions, and is not associated with the screw. The combination of the adjustment mechanism and the two adjustment screws avoids the failure of the adjustment mechanism. Locking or stagnation occurs at the connecting parts, no matter there is any fault in the main adjustment or slave adjustment function, it will not affect the normal operation of the overall braking mechanism, which can ensure that the brakes are normal and effective no matter what the situation is, and the structure of the adjustment mechanism will be simplified, so that Braking parallelism and stability are greatly improved.

Description

technical field [0001] This product involves pneumatic disc brake gap automatic adjustment mechanism components, mainly used for automatic adjustment of disc brake gaps such as high-end passenger cars, heavy trucks, trailers, etc., to ensure constant brake gaps and continuous and effective four-gear linkage brakes Gap adjustment device. Background technique [0002] At present, the disc brakes of passenger cars and trucks all have gap adjustment mechanisms. The gap adjustment mechanisms of disc brakes have structures such as chain transmission and gear transmission. Most of the gear transmission is the combination of the main adjuster and the slave adjuster itself with the adjustment screw. The adjuster drives the slave adjuster to realize the double push rod movement. If manual adjustment is required, another manual adjuster needs to be added. This kind of gear transmission structure is very complicated because the main tuner and the slave tuner themselves not only need to...

AI Technical Summary

Problems solved by technology

This kind of gear transmission structure is very complicated because the main tuner and the slave tuner themselves not only need to realize the adjustment function, but also realize the adjustment function of the adjustment screw, and also add a transitional gear in the middle to realize the linkage. If the adjustment fails, the adjustment screw will be stuck and locked, and the entire product function will fail, which will directly affect the braking performance
