本实施例中, 采用优先阔 (39) 以保证轮胎行驶时候优先满足全液压转向器的供油 量, 保证转向灵活、 轻便, 采用组合阀块(37)可以起到吸收转向油路压力冲击和压力 过载保护作用。采用散热齿轮马达驱动风冷液压油散热器, 可以及时将系统在工作中产 生的热量散发, 有效控制系统液压油温度在最佳值范围内, 防止油温过高, 造成密封件 的老化和损坏,对系统进行污染, 同时也防止液压油温过高导致液压油粘度下降而影响 系统的动态性能。
本实施例中, 采用吸油过滤器 (44)和回油过滤器(45)有效的过滤系统中的各种 杂质, 保证了液压油的清洁度。 采用的空气滤清器(46)也有效的防止加油过程中混入 的杂质污染了液压油。 回油路上的背压阀(40)给系统设置了一定压力值的背压, 此背 压值给系统中工作的各种马达执行器提供了良好的补油条件, 改善了马达工作条件,有 效的延长马达使用寿命。
本实施例中, 采用控制下车 "Y"型支腿油缸 (26) 放开, 可以提高现场救援整车 的稳定性, 当整车需要快速移动时候, 可以将 "Y" 型支腿油缸收回来, 縮短整车的横 向尺寸, 提高移动灵活性, 双向液压锁 1 ( 25 ) 起到将油缸无杆腔锁紧作用。
本实施例中,采用下车推土铲油缸控制的推土铲机构可以有效的清理整车行走时候 前方路面上障碍物, 同时双向液压锁 2 ( 35 ) 起到将油缸无杆腔锁紧作用。
本实施例中, 采用下车轮胎行走马达(31 )驱动变速箱(32 ), 再通过变速箱(32 ) 来同时驱动前桥(34)和后桥 (28 ) 。 采用前后双驱动方式, 提高了整机驱动力矩, 提 高了整机的爬坡和越障能力, 使其能更好适应救援现场路况。 同时行走制动阀 (30 )在 液压系统停止给下车轮胎行走马达(31 )供油后, 可以在马达两个工作口之间形成一个 局部液压回路, 可以给马达补油, 同时也可以吸收马达工作口的压力冲击, 对整车行走 起到缓冲滑行作用。
在本说明书的描述中, 参考术语 "一个实施例" 、 "一些实施例" 、 "示意性实施 例" 、 "示例" 、 "具体示例" 、 或 "一些示例"等的描述意指结合该实施例或示例描 述的具体特征、 结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说 明书中, 对上述术语的示意性表述不一定指的是相同的实施例或示例。而且, 描述的具 体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结 合。
尽管已经示出和描述了本发明的实施例, 本领域的普通技术人员可以理解: 在不脱 离本发明的原理和宗旨的情况下可以对这些实施例进行多种变化、 修改、 替换和变型, 本发明的范围由权利要求及其等同物限定。
