停车制动系统又称手制动系统,是用于机械或车辆停车后保持原位置不动的装置,有时也用于紧急制动。目前国内装载机多采用软轴推拉式停车制动系统,它通过手柄拉动软轴,将安装在变速器输出轴上的制动蹄片张开并与制动鼓产生摩擦力,从而实现停车制动。我公司988H型轮式装载机采用自主研发的常闭式液压释放和弹簧制动的停车制动系统,进一步提高了停车制动性能。
Parking brake system, also known as hand brake system, is used for mechanical or vehicle parking to maintain the original position of the device, and sometimes also for emergency braking. At present, most domestic loaders use the soft-shaft push-pull parking brake system, which pulls the flexible shaft through the handle and opens the brake shoe mounted on the output shaft of the transmission to generate friction with the brake drum so as to realize the parking brake . Our company 988H Wheel Loader adopts self-developed normally closed hydraulic brake release and spring brake parking brake system to further improve the parking brake performance.
