论汽车手刹机械式驻车制动系统效率提升策略

The Automobile Brake Mechanical Brake System to Enhance the Efficiency of the Strategy

用手来操纵的传统式"手刹"因价格低,目前还是被广泛地应用在汽车上。如果设计时各种因素匹配不好,就会要求操纵驻车手柄的力要很大才能驻坡,操纵力小的时候驻车制动力会不足,导致溜车。所以提高手刹机械式驻车制动系统的效率至关重要。本文详细描述几种提高手刹机械式驻车制动系统效率的策略,结果显示:拉索设计时走向尽可能地平顺最小工作曲率半径大于200 mm;钢丝绳使用好的润滑脂;加大耐压软管内孔尺寸;钢丝绳的材质要选择合适这几种方法,对提升拉索的效率很有帮助。

The traditional ＂manipulated by hand brake＂ due to low prices, is still widely used in automobile. If the design of a variety of factors are not good, you will slope, the control force is small when parking braking need to handle the handle of the car to a large force in the force will be insufficient, leading to the car. So to improve the efficiency of critical brake mechanical parking brake system. This paper describes several methods to improve the efficiency of manual mechanical brake system strategy, results show that the cable design trend as smooth as possible minimum working radius is greater than 200mm; the use of wire rope grease well; to increase the size of pressure hose inner hole; the wire rope should choose the appropriate material of these methods is very helpful to improve the efficiency of cable.
