双向行驶特种车辆及其转向系统
摘要：
本发明提供了一种双向行驶特种车辆及其转向系统。转向系统包括主车转向装置和副车转向装置；主车转向装置包括转向桥以及能够接受主车方向盘控制而驱动转向桥转向的主车转向驱动机构；副车转向装置包括副车动力单元、副车转向器、切换单元以及转向执行机构；副车动力单元能够接受副车方向盘控制而给副车转向器提供动力；切换单元分别连接副车转向器和转向执行机构，并能够建立或解除副车转向器与转向执行机构之间的连接；转向执行机构连接主车转向装置的转向桥，并在与副车转向器形成连接时，在副车转向器驱动下驱动转向桥转向。本发明在保留主车转向结构的基础上实现了副车与主车转向的桥接，实现双向行驶转向。
摘要（英）：

The invention provides a bidirectional running type special vehicle and a steering system thereof. The steering system comprises a main vehicle steering device and a sub vehicle steering device. The main vehicle steering device comprises a steering axle and a main vehicle steering driving mechanism capable of being controlled by a main vehicle steering wheel to drive the steering axle to steer. The sub vehicle steering device comprises a sub vehicle power unit, a sub vehicle steering gear, a switching unit and a steering executing mechanism. The sub vehicle power unit can be controlled by a sub vehicle steering wheel to supply the power to the sub vehicle steering gear. The switching unit is connected with the sub vehicle steering gear and the steering executing mechanism and can establishor disconnect the connection between the sub vehicle steering gear and the steering executing mechanism. The steering executing mechanism is connected with a steering axle of the main vehicle steering device and drives the steering axle to steer under the drive of the sub vehicle steering device when being connected with the sub vehicle steering device. On the basis that a main vehicle steering structure is reserved, a sub vehicle frame and a main vehicle frame are bridged in steering operation. Therefore, the bidirectional driving steering is achieved.
