Abstract

The invention provides a steering control valve, and belongs to the technical field of automobile equipment. The steering control valve solves the problem that an existing steering control valve can still cause floating feeling when an automobile runs at a high speed. The steering control valve comprises a valve body, and a valve sleeve is mounted in the valve body; a valve core capable of relatively rotating is arranged in the valve sleeve; an oil control valve cavity is formed between the outer side face of the valve element and the inner side face of the valve sleeve. An oil inlet hole, anoil return hole, a left oil passing hole and a right oil passing hole are formed in the valve body. The valve sleeve comprises an adjusting part, and an adjusting cavity is formed between the outer side surface of the adjusting part and the inner side surface of the valve body; a bypass channel communicated with the oil inlet hole and the adjusting cavity is formed in the valve body, a flow adjusting valve is connected into the bypass channel, a plurality of through holes are evenly formed in the adjusting part in the circumferential direction, the inner ends of the through holes are communicated with the oil return hole, movable steel balls are installed in the through holes, and the inner sides of the steel balls can abut against the outer side face of the valve core. The steering control valve can more effectively prevent the problem of drifting of an automobile during high-speed driving and steering.

Description

technical field [0001] The invention belongs to the technical field of automobile equipment and relates to a steering control valve. Background technique [0002] The steering system refers to the device used to change or maintain the direction of driving or reversing of the car. The function of the steering system of the car is to control the driving direction of the car according to the driver's wishes. The steering system includes a mechanical steering system and a power steering system. The mechanical steering system uses the driver's physical strength as the steering energy, while the power steering system uses the driver's physical strength and engine power as the steering energy. Currently, the power steering system is commonly used in automobiles. [0003] Hydraulic power steering system is a common power steering system, including steering gear, steering power cylinder, steering control valve, oil storage tank and power steering pump, etc. The steering gear is a ra...
