Problems solved by technology

[0003] The purpose of the present invention is to provide an automatic centering steering system for the existing full hydraulic steering vehicles with poor steering operability and potential safety hazards. component, and an elastic element is set between the moving component and the relatively fixed component, and the energy storage characteristic of the elastic element is used to reserve the steering power, so that after the steering power is withdrawn, the elastic element is used to automatically return to normal, and at the same time, the elastic element forms Steering resistance enables the driver to obtain force feedback that the larger the steering angle, the heavier the steering wheel, thereby increasing alertness and reducing the risk of accidents

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the described embodiments.

[0016] see figure 1 , an automatic back-to-center steering system, including a full hydraulic steering gear 9 controlled by a steering wheel 5, the steering wheel 5 and the full hydraulic steering gear 9 are connected through a transmission shaft; the transmission shaft includes a lead screw 7, and the lead screw 7 is rotatable through its two ends Supported on the fixed base 1, the lead screw 7 is screwed with a movable nut 3, and an elastic element 4 is arranged between the front and rear ends of the nut 3 in the moving direction and the opposite sides corresponding to the fixed base 1; Both the bar 7 and the nut 3 adopt a ball structure, and the two form a ball screw nut secondary structure.

[0017] Wherein, the elastic element 4 is composed of one of cylindrical helical compressio...

Abstract

The invention discloses an automatic aligning steering system. The automatic aligning steering system comprises a full hydraulic steering gear controlled by a steering wheel; the steering wheel is connected with the full hydraulic steering gear through a transmission shaft; the transmission shaft comprises a lead screw; the lead screw is rotatably supported on a fixed base through the two ends ofthe lead screw; movable nuts are screwed on the lead screw; and elastic elements are arranged between the front and rear ends in the moving direction of the nut and the corresponding opposite sides ofthe fixed base. Preferably, the elastic element consists of one of a cylindrical helical compression spring, a cylindrical helical extension spring or a gas spring. The automatic aligning steering system has the beneficial effects that the direction can be automatically aligned, and the potential safety hazards caused by the fact that the direction cannot be aligned is eliminated; at the same time, the automatic aligning steering system can give a driver an intuitive feeling of the steering angle, and is helpful for the driver to actively implement safety control; and the automatic aligning steering system is simple in structure, reliable in function and wide in application range.

Description

technical field [0001] The invention relates to vehicle driving control technology, in particular to an automatic centering steering system for full hydraulic steering. Background technique [0002] On a traditional vehicle using a full hydraulic steering system, due to the limitation of the steering system structure, after the driver releases the steering wheel, the steering wheel cannot automatically return to the middle position, and the wheels will not automatically return to the straight-line driving position. If you don't know the direction position or forget the direction position during the next operation, it will easily lead to driving accidents. In addition, no matter how large the steering wheel angle is, the driver's hand steering wheel is the same, which causes the steering angle of the vehicle to not be fed back to the driver in time, making it difficult to control the steering angle, poor operability, and easily leading to safety accidents. For this reason, i...
