Remote control steering system for vehicle and vehicle with remote control steering system

Abstract

The invention discloses a vehicle and a remote control steering system of the vehicle. The remote control steering system comprises a steering power cylinder, a rotary valve, an oil pump and a two-way oil pump. A power cylinder piston is arranged in the steering power cylinder, the interior of the steering power cylinder is divided by the power cylinder piston into a left cavity and a right cavity, and piston rods are arranged on the two sides of the power cylinder piston respectively. The rotary valve is provided with an oil inlet, an oil return port, a left oil port and a right oil port, wherein the left oil port is connected with the left cavity through a first mechanical sliding valve, and the right oil port is connected with the right cavity through a second mechanical sliding valve. The oil pump is connected with the oil inlet. The two-way oil pump is provided with a first oil port and a second oil port, wherein the first oil port is connected with the left cavity through the first mechanical sliding valve, and the second oil port is connected with the right cavity through the second mechanical sliding valve. The remote control steering system can be operated in a manual mode and a remote control mode, is simple in structure and low in cost, and convenient to control, and can fulfill the function of the preference to the manual mode.

Description

technical field [0001] The invention relates to the field of automobile construction, in particular to a remote control steering system for vehicles and a vehicle with the remote control steering system. Background technique [0002] The function of the car steering system is to ensure that the car can turn according to the will of the driver. Automobile steering system can be divided into mechanical steering system and power steering system. The mechanical steering system uses the driver's physical strength as the steering energy, and all the force transmission parts are mechanical structures, mainly composed of three parts: the steering mechanism, the steering gear and the steering transmission mechanism. The power steering system is a steering system that uses both the driver's physical strength and engine power as the steering energy. The power steering system is mainly equipped with a steering booster device. The steering booster device is mainly a hydraulic steering b...

Problems solved by technology

[0003] In the related technology known to the inventor, a remote control steering system appeared on the basis of the power steering system, which has two modes of manual and automatic, and can realize functions such as automatic parking, but the relevant remote control steering system known to the inventor The structure is complex, the control is cumbersome, the cost is high, and the practicability is poor, and these remote control driving technologies are all developed based on electric power steering (EPS), but many electric power steering (EPS) are not particularly mature, especially for Vehicles with heavy front axle loads need to develop high-power brushless motors. During remote driving, the electric power steering (EPS) will often perform in-situ steering. At this time, the load on the steering device is the largest, and the electric power steering (EPS) EPS) motor will generate a lot of heat and cause the motor to enter self-protection mode, which greatly reduces the life of the electric power steering (EPS) motor
