在轮胎式建筑机械中,常采用蹄式制动器这种结构形式。蹄式制动器的计算方法甚多,但可以归纳为下列两大类。第一类,假定制动蹄的摩擦衬片和制动毂之间的单位压力P沿制动蹄摩擦衬片的包角θ是均匀分布的,也就是说,从假定P为常数出发来进行计算的,其计算简图见图1。图2),即在制动蹄上作CO OA,点C处具有最大单位压力值;偏离点C的角度越大,p值越小;当偏离点C的角度为90°处(即点A处),p值等于零。图2中符号的含义同图1。

In the tire construction machinery, often used shoe brake this structure. There are many ways to calculate the shoe brake, but it can be summarized into the following two categories. In the first type, it is assumed that the unit pressure P between the friction lining of the brake shoe and the brake hub is uniformly distributed along the wrap angle θ of the brake shoe friction lining, that is, from the assumption that P is a constant Calculated, the calculation diagram shown in Figure 1. Figure 2), that is, in the brake shoe for CO OA, the maximum pressure unit C at the point; the larger the angle from the point C, the p value is smaller; when the angle from the point C is 90 ° P) is equal to zero. The meaning of symbols in Figure 2 is the same as Figure 1.
