混凝土攪拌車制動踏板行程過大,制動作用遲緩,制動效能很低甚損失,混凝土攪拌車制動間隔增加。
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.
問題原因:
Cause of the problem:
1、制動油壓力缺乏。(制動主缸缺油、制動管路決裂、油管接頭滲漏、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、制動系統內有空氣。
2. There is air in the brake system.
3、制動踏板自在行程或制動器空隙過大,制動蹄摩擦片接觸不良,小攪拌車磨損嚴重或有油污。
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、制動主缸、輪缸活塞和缸管磨損或拉傷,皮碗老化損壞。
4. The brake master cylinder, wheel cylinder piston and cylinder pipe are worn or strained, and the leather cup is aged and damaged.
