The invention discloses an axle steering system and a vehicle, the axle steering system comprises a steering gear, a first longitudinal pull rod, a second longitudinal pull rod and a connecting rod transmission mechanism, the first longitudinal pull rod is connected with a first front axle and the steering gear and is driven by the steering gear to pull the first front axle to steer; a second longitudinal pull rod is connected with the second front axle and used for pulling the second front axle to steer, a cylinder body of a double-rod piston type booster cylinder of the connecting rod transmission mechanism is fixedly arranged on the portion, between the first front axle and the second front axle, of the frame, and the front piston rod end of the double-rod piston type booster cylinder is hinged to a steering gear. The rear piston rod end of the double-rod piston type booster cylinder is hinged to the end, away from the second front axle, of the second longitudinal pull rod, a connecting rod system is simplified through the double-rod piston type booster cylinder, transmission hinge points are greatly reduced, and the purposes of improving system rigidity and transmission efficiency and reducing design and analysis workloads are achieved.

    本发明公开一种车桥转向系统及车辆,车桥转向系统包括转向器、第一纵向拉杆、第二纵向拉杆和连杆传动机构,第一纵向拉杆连接第一前桥和转向器并在转向器的驱动下拉动第一前桥转向,第二纵向拉杆与第二前桥连接并用于拉动第二前桥转向,连杆传动机构的双杆活塞式助力缸的缸体固设于第一前桥和第二前桥之间的车架上,双杆活塞式助力缸的前置活塞杆端与转向器铰接,双杆活塞式助力缸的后置活塞杆端与第二纵向拉杆用于远离第二前桥的一端铰接,通过采用双杆活塞式助力缸精简了连接杆系,大大减少了传动铰点,达到提升系统刚度和传动效率以及减少设计分析工作量的目的。
