本发明涉及商用车驾驶室悬架系统技术领域,具体涉及一种驾驶室后悬液压锁、后悬支架结构以及悬架总成,包括外壳、设置在外壳的底部的限位结构和设置在外壳内的液压锁具;外壳用于与横向减振器的一端铰接连接,液压锁具用于将后悬上支架连接在外壳的顶端,外壳的底部用于与第一气囊减振器的上吊耳铰接连接;限位结构用于与第一气囊减振器的上盖的外周面相配合,以限制第一气囊减振器绕第一气囊减振器的上吊耳的铰接点的转动,以解决车辆行驶过程中产生的颠簸会使现有的后悬液压锁产生绕气囊减振器上吊耳中心的旋转运动,使锁体导向槽与后悬上支架的锁销之间的碰撞与摩擦加剧,产生异响,还会加剧锁体导向槽与后悬上支架的锁销之间的磨损的问题。

    The invention relates to the technical field of commercial vehicle cab suspension systems, in particular to a cab rear suspension hydraulic lock, a rear suspension support structure and a suspension assembly, comprising a shell, a limiting structure arranged at the bottom of the shell and a hydraulic lock arranged in the shell; the shell is used for being hinged to one end of a transverse shock absorber, the hydraulic lock is used for connecting the rear suspension upper support to the top end of the shell, and the bottom of the shell is used for being hinged to an upper lifting lug of a first air bag shock absorber. The limiting structure is used for being matched with the peripheral face of an upper cover of the first air bag shock absorber so as to limit the first air bag shock absorber to rotate around a hinge point of an upper lifting lug of the first air bag shock absorber, and therefore the problem that an existing rear suspension hydraulic lock rotates around the center of the upper lifting lug of the air bag shock absorber due to bumping generated in the running process of a vehicle is solved. The problems that collision and friction between a lock body guide groove and a lock pin of the rear overhang upper support are intensified, abnormal sound is generated, and abrasion between the lock body guide groove and the lock pin of the rear overhang upper support is intensified are solved.
