The invention discloses a trailer collision brake which comprises a trailer rod assembly used for being connected with a tractor and further comprises a brake pump assembly, a collision rod assembly and a brake rod assembly arranged on a trailer frame. A brake cavity is formed in the brake rod assembly, and an opening is formed in one end of the brake cavity; the brake end of the collision rod assembly is matched with the opening; the collision rod assembly penetrates through the opening and is inserted into the brake cavity; the collision rod assembly is connected with the brake rod assembly through a limiting piece, so that the collision rod assembly can move in the brake cavity in the axial direction of the brake cavity all the time; the trailer rod assembly is arranged at the end, away from the brake pump assembly, of the collision rod assembly; the output end of the brake pump assembly is used for being communicated with a front axle brake assembly of the trailer; the input end of the brake pump assembly penetrates through the end, away from the opening, of the brake cavity, so that the collision rod assembly can collide with the input end of the brake pump assembly, and the front axle brake assembly is braked. Passive braking is converted into active braking, and the safety of the trailer in the traction process is improved.
本发明公开了一种拖车撞刹,包括用于与牵引车连接的拖车杆总成,还包括制动泵总成、撞杆总成和装设于拖车车架上的制动杆总成;制动杆总成内具有制动腔体,制动腔体的一端具有开口;撞杆总成的制动端与开口相匹配;撞杆总成穿过开口设置并插设于制动腔体内;撞杆总成通过限位件与制动杆总成连接,使撞杆总成能够始终在制动腔体内沿制动腔体的轴向移动;拖车杆总成装设于撞杆总成远离制动泵总成的一端;制动泵总成的输出端用于与拖车的前桥制动总成连通;制动泵总成的输入端穿过制动腔体远离开口的一端设置,使撞杆总成能够撞击制动泵总成的输入端并使前桥制动总成制动。本发明通过将被动制动转换为主动制动,提高拖车被牵引过程的安全性。
