货车自动制动装置由风动部分和机械部分组成。机械部分中的杠杆传动装置借助于制动杠杆、制动梁、制动拉杆及制动轴,可以扩大和分配制动缸勾贝杆所产生的力。在一根制动梁上装有两块闸瓦。制动梁装在固定于侧架上的闸瓦托吊上,或者当不带托吊时,制动梁两端安装在转向架侧架上的特殊倾斜导向装置上。图1为长26米的平车标准杠杆传动装置的示意图。制动缸传到闸瓦上的力,可以用修改制动杠杆臂的长短来调整。
Truck automatic braking device consists of pneumatic parts and mechanical parts. Lever gearing in the mechanical part The force generated by the brake cylinder stem can be increased and distributed by means of the brake lever, the brake beam, the brake lever and the brake shaft. Two brake shoes are mounted on a brake beam. The brake beam is mounted on a brake shoe mount secured to the side frame or both ends of the brake beam are mounted on a special tilt guide on the side frame of the truck when not in use. Figure 1 is a schematic diagram of a standard 26-meter-long standard lever drive. Brake cylinder reached the brake shoe on the force, you can modify the length of the brake lever arm to adjust.
