混凝土搅拌车制动踏板行程过大,制动作用迟缓,制动效能很低甚损失,混凝土搅拌车制动间隔增加。
The brake pedal stroke of concrete mixer is too large, the brake action is slow, the brake efficiency is very low or even lost, and the brake interval of concrete mixer increases.
问题原因:
Cause of the problem:
1、制动油压力缺乏。(制动主缸缺油、制动管路决裂、油管接头渗漏、油路堵塞)
1. Lack of brake oil pressure( The brake master cylinder is short of oil, the brake pipe is cracked, the oil pipe joint is leaking, and the oil circuit is blocked.)
2、制动系统内有空气。
2. There is air in the brake system.
3、制动踏板自在行程或制动器空隙过大,制动蹄摩擦片接触不良,小搅拌车磨损严重或有油污。
3. The brake pedal free travel or brake clearance is too large, the brake shoe friction plate contact is poor, and the small mixer is seriously worn or greasy.
4、制动主缸、轮缸活塞和缸管磨损或拉伤,皮碗老化损坏。
