The invention discloses a control system suitable for full hydraulic drive of a wheel step type vehicle, the control system comprises a control system and a hydraulic drive system, and the control system comprises a brake solenoid valve, a four-wheel drive change-over switch, an intermediate relay, an intermediate relay normally open contact and a solenoid valve coil. The hydraulic driving system comprises an oil pump, a first constant displacement motor, an electromagnetic valve, a second constant displacement motor and a third constant displacement motor. Two oil inlets and outlets of the brake electromagnetic valve are respectively connected with two connecting pipelines for connecting the servo control valve and the variable pump servo control cylinder through pipelines; the four-wheel drive change-over switch is serially connected with the intermediate relay and then serially connected with the power supply to form a four-wheel drive change-over loop; a normally open contact of the intermediate relay, a solenoid valve coil and a power supply are sequentially connected in series to form a four-wheel-drive starting control loop; the two control loops share a power supply.
本发明公开了一种适用于轮步式车辆全液压驱动的控制系统,由控制系统及液压驱动系统构成,其中控制系统包括刹车电磁阀、四驱转换开关、中间继电器、中间继电器常开触点、电磁阀线圈。液压驱动系统包括油泵、一号定量马达、电磁阀、二号定量马达和三号定量马达。刹车电磁阀的两进出油口分别通过管路与连接伺服控制阀与变量泵伺服控制缸的两个连接管路相连;四驱转换开关与中间继电器串接后再与电源串接形成四驱转换回路;中间继电器常开触点、电磁阀线圈及电源依次串联形成四驱启动控制回路;两个控制回路电源共用。
