Description

大型煤矿用车辆反转四连杆大角度前轮转向系统
技术领域
本发明属于煤矿用辅助运输车辆转向系统的技术领域，具体涉及一种大型煤矿用车辆反转四连杆大角度前轮转向系统。
背景技术
煤矿井下巷道狭窄，视线有限，对车辆转弯半径要求及其严格，对于大型煤矿用辅助运输车辆来说，一般采用中央铰接转向机构或转向桥，转向角最大约为45°，远远不能满足巷道内转弯和掉头要求。而且中央铰接转向机构会增加整车车长，而转向桥除了承受垂直载荷以外，还承受车辆加速、制动等产生的纵向力和车辆转弯引起的侧向力，受力复杂，对车辆操作稳定性有较大影响。
类似的转向系统无悬挂系统，车辆行驶过程中减震效果差，大多为对称四连杆转向机构，占用空间较大且转向角度受限。
发明内容
本发明为了解决现有的转向机构用于煤矿井下车辆不能满足使用要求的问题，提供了一种大型煤矿用车辆反转四连杆大角度前轮转向系统。本发明采用如下的技术方案实现：一种大型煤矿用车辆反转四连杆大角度前轮转向系统，包括左、右对称设置的轮胎组件，轮胎组件通过轮轴箱连接固定于与机架连接的油气悬挂油缸上，油气悬挂油缸的活塞和缸筒分别与下扭梁和上扭梁连接，下扭梁和上扭梁铰接连接，左、右两侧的油气悬挂油缸之间连接有反转四连杆机构，反转四连杆机构包括动力转向油缸、转向驱动臂和转向推力杆，转向驱动臂通过与其铰接连接的转向推力杆分别与左、右轮胎组件铰接连接，转向驱动臂左右两侧还分别铰接有动力转向油缸，转向驱动臂与机架由连接销连接固定。
油气悬挂油缸与机架之间设有双向推力轴承和圆锥滚子轴承实现相对转动，双向推力轴承和圆锥滚子轴承之间加装有轴套固定两者距离，油气悬挂油缸顶部设有压板，油气悬挂油缸与机架上端由端盖固定密封。
油气悬挂装置包括油气悬挂油缸、上扭梁和下扭梁，可通过其上下位移调整实现车辆减震。
反转四连杆机构实现前轮转向，由动力转向油缸、转向驱动臂、转向推力杆组成，通过动力转向油缸伸缩调整来控制转向角度。
反转四连杆机构与油气悬挂装置之间均通过铰接销进行连接。
机架与油气悬挂装置通过双向推力轴承、圆锥滚子轴承实现机架与油气悬挂油缸之间旋转运动。
与现有技术相比，本发明可通过控制动力转向油缸，通过反转四连杆机构，实现双前轮的近似90°大角度转向（原地转向），可有效解决大型煤矿车辆在井下转弯通过性差的问题，并可以在路况恶劣的情况下，通过油气悬挂系统实现车辆减震。本发明结构新颖，安装便捷，操作简单，可大大减少对轮胎的磨损。
