1气压制动器咬死车辆在制动减速后,松开踏板加速时,车速不能提高,停车后难起步。分析故障原因:(1)快放阀被卡死,打不开,使相应的制动气室的气体不能排出,使车轮制动器不能解除制动。(2)踏板无自由行程,当松开踏板后主制动控制阀内的排气阀打不开,阀内的气体不能排出,使快放阀不能打开,制动气室内的气体不能排出,使制动器不能解除制动。(3)制动装置机械传动机构中的拉臂轴或制动器凸轮轴的阻力
1 pneumatic brake biting vehicle braking deceleration, release the pedal acceleration, the speed can not be increased, difficult to start after stopping. Analysis of the cause of the malfunction: (1) quick release valve stuck, can not open, so that the corresponding brake gas chamber can not be discharged, so that the wheel brake can not lift the brake. (2) The pedal has no free stroke. When the pedal is released, the exhaust valve in the main brake control valve can not be opened, the gas in the valve can not be discharged, the quick release valve can not be opened, and the gas in the brake gas chamber can not be discharged. So that the brake can not be released. (3) Braking device Drag of arm shaft or brake camshaft in mechanical transmission mechanism
