The invention discloses an internal combustion forklift steering system. The internal combustion forklift steering system comprises an oil tank, a main working oil pump, a priority valve, a full hydraulic steering device and a steering oil cylinder which are connected in sequence. The internal combustion forklift steering system further comprises an emergency steering device. An oil inlet of the emergency steering device is connected with the oil tank, an oil outlet of the emergency steering device is connected with an oil inlet of the full hydraulic steering device, the emergency steering device comprises an emergency oil pump and a motor for driving the emergency oil pump, and the motor is connected with a storage battery of an internal combustion forklift. When conventional steering isabnormal and failed due to an engine fault, the motor can be started, so that the pressure is provided for the full hydraulic steering device through the emergency oil pump, the forklift steering function is continuously achieved, and therefore potential safety hazards caused by sudden failure of the conventional steering function are avoided; and meanwhile, when the forklift stops and towing is needed, the emergency steering device can be manually controlled, and the steering function during the towing is achieved. The invention further discloses the internal combustion forklift including thesystem.
本发明公开一种内燃叉车转向系统,包括依次连接的油箱、主工作油泵、优先阀、全液压转向器和转向油缸,还包括应急转向装置,应急转向装置的进油口连接油箱,应急转向装置的出油口连接全液压转向器的进油口,应急转向装置包括应急油泵和驱动应急油泵的电机,电机连接内燃叉车的蓄电池。当出现发动机故障等导致常规转向异常失效,可以启动电机,进而通过应急油泵为全液压转向器提供压力,继续实现叉车转向的功能,从而避免因常规转向功能突然失效而产生的安全隐患,同时当叉车停止且需要拖车时,可以手动控制应急转向装置,实现拖车时的转向功能。本发明还公开一种包括上述系统的内燃叉车。
