The utility model discloses a rear suspension device of a cab, whose structure is completely symmetrical. It mainly consists of lower support, spring shock absorber assembly, locking support assembly, hydraulic lock assembly and swing arm. The lower support is fixed to the frame. The upper end of the spring shock absorber assembly is articulated with the swing arm and the lower end is articulated with the lower support. The upper end of the locking bracket assembly is securely connected with the cab, and the lower end is matched with the hydraulic lock assembly after the cab falls back. The hydraulic lock assembly is fixed with the swing arm. The swing arm is articulated with the lower support to improve the stability of the cab motion. The polyurethane bushing at the hinge of swing arm and lower support can absorb large deformation. There are rubber bushes at both ends of the pin shaft of the locking bracket assembly, so that the locking can be carried out smoothly. There are rubber bushes in the lifting ears at both ends of the spring shock absorber assembly, which can reduce the abnormal noise at the connection. Left and right mounting without connecting beams, suitable for installation of different engines. The structure has the advantages of strong bearing capacity, good vibration reduction, compact structure and strong versatility, which can effectively improve the comfort of vehicles in the process of driving.
【技术实现步骤摘要】
一种驾驶室后悬置装置
本技术涉及一种汽车辅助装置，具体涉及载重汽车驾驶室的后悬置装置。
技术介绍
随着我国交通运输业的发展和科学技术的进步，人们对重卡的舒适性要求也越来越高。目前国内主要载重汽车均采用带有螺旋弹簧或空气弹簧的后悬置装置，该结构形式能够衰减由车架传递到驾驶室的震动，提高驾驶室的舒适性。但由于后悬置下方通常布置发动机，横梁位置常常发生干涉。
技术实现思路
为了提高驾驶室的舒适性稳定性，改善后悬置装置与发动机干涉等情况，本技术提供一种驾驶室后悬置装置。具体实施方案如下：一种驾驶室后悬置装置，其自身结构完全对称，主要由下支座、弹簧减震器总成、锁紧支架总成、液压锁总成、摆臂等组成。下支座通过螺栓螺母与车架固连。弹簧减震器总成上端通过螺栓螺母与摆臂铰接，下端通过螺栓螺母与下支座铰接。锁紧支架总成上端通过螺栓螺母与驾驶室固连，下端在驾驶室落回后与液压锁总成配合。液压锁总成通过螺栓螺母与摆臂固连。摆臂通过螺栓螺母与下支座铰接。本技术的另一优选方式：摆臂与下支座铰接，可实现摆动动作，控制后悬置装置的运动轨迹，提高驾驶室运动的稳定性。本技术的另一优选方式：摆臂与下支座铰接处有的聚氨酯衬套，较橡胶衬套可吸收更大变形，利于消除悬置装置纵向变形。本技术的另一优选方式：锁紧支架总成销轴两端有橡胶衬套，橡胶衬套的变形可以抵消悬置装置和驾驶室的累计误差，使锁紧支架顺利入锁。本技术的另一优选方式：弹簧减震器总成两端吊耳内有橡胶衬套，可以抵消吊耳轴向的变形，铰接处软连接可以减小连接处异响。本技术的另一优选方式：左右悬置无连接横梁，便于不同发动机的安装，避免发生干涉。本技术结构简单...
