The utility model relates to an asymmetric air suspension structure for a double rear axle vehicle, which is advantageous to lightweight frame, convenient maintenance and replacement, convenient to arrange brake valves, stress on thrust rods, reduce tire wear, and meet the strength requirements of heavy-duty suspension, including air suspension structure, which is fixed under the web of the frame, and horizontally arranged at the center of the middle bridge/rear axle. The frame webs are connected with the mid-bridge/rear axle by V-type thrust rod, in which the frame webs are connected to the V-type ends of the V-type thrust rod through three supports, and the top of the V-type thrust rod is connected with four supports on the mid-bridge/rear axle. In the utility model, the asymmetric V-type suspension structure is used to lighten the frame without installing the lateral stabilizer rod; the V-type thrust rod adopts the left-right asymmetric structure to facilitate the arrangement of brake valves; the thrust rod of the asymmetric V-type suspension structure should bear force to reduce tire wear; and the asymmetric V-type suspension structure meets the strength requirement of heavy-duty suspension.

一种双后桥车辆非对称式空气悬架结构
本技术涉及后双桥车辆的空气悬置,具体是一种双后桥车辆非对称式空气悬架结构。
技术介绍
目前载重车的双后桥车辆采用空气悬架结构,为了能够在车辆转弯过程中对整个空气悬架起到安全和保护作用,增加多根I型推力杆,如图1/2所示,空气悬架结构1采用2个单根I型推力杆2,水平布置于中桥和后桥中心处。单根I型推力杆2连接一个支座一3固定于车架腹板4上;I型推力杆2连接一个另支座二5固定于中桥/后桥上(此时未显示),该结构中I型推力杆2强度不足,稳定性差,布置后占用中间位置前后空间过小。
技术实现思路
本技术为了能够利于车架轻量化,方便维护更换,便于制动阀类的布置,推力杆均应受力,减小轮胎磨损,满足重型载悬架强度需求,特提出一种双后桥车辆非对称式空气悬架结构。为此本技术的技术方案为,一种双后桥车辆非对称式空气悬架结构,空气悬架结构,空气悬架结构固定于车架腹板下,并水平布置于中桥/后桥中心处,其特征在于:车架腹板和中桥/后桥之间通过V型推力杆连接,其中车架腹板通过支座三连接于V型推力杆的V型两端;中桥/后桥上通过支座四连接V型推力杆的顶端。进一步的改 ...
