The invention relates to the technical field of brakes, in particular to a forklift brake assembly which comprises a parking piston, a cylinder body and a driving piston and further comprises a first spring and a second spring, the parking piston is in sliding connection with the cylinder body, the driving piston is also in sliding connection with the cylinder body, and the side, away from the cylinder body, of the driving piston is used for abutting against a friction plate. The parking piston and the driving piston are arranged on the two sides of the cylinder body respectively and abut against each other, the first spring is used for pushing the parking piston to move towards the driving piston, the second spring is used for pulling the driving piston to move towards the cylinder body, and the thrust of the first spring is larger than that of the second spring. Friction braking is conducted through the parking piston and the driving piston, the driving piston can be pushed by the parking piston to make whole-face contact with the friction plate, the braking effect can be further improved by increasing the contact area, meanwhile, the contact position can be more uniform during braking, and the problem of braking failure caused by abrasion can be further solved.
本发明设计涉及制动器技术领域,尤其是涉及一种叉车制动器总成,包括驻车活塞、缸体、行车活塞,还包括第一弹簧与第二弹簧,驻车活塞与缸体滑动连接,行车活塞也与缸体滑动连接,行车活塞远离缸体的一侧则用于抵接摩擦片,驻车活塞与行车活塞分别设置于缸体的两侧,驻车活塞与行车活塞互相抵接,第一弹簧用于推动驻车活塞朝向行车活塞运动,第二弹簧则用于拉动行车活塞朝向缸体运动,第一弹簧的推力大于第二弹簧的推力。采用驻车活塞与行车活塞进行摩擦刹车,行车活塞能够被驻车活塞推动整面接触摩擦片,增大接触面积能够进一步提高刹车效果,同时能够使得刹车时接触位置更为均匀,能够进一步减少因磨损而导致刹车失效的问题。
