The invention discloses an electro-hydraulic valve-controlled steering gear capable of changing the steering feel, which comprises a housing, and a valve core assembly, a valve body assembly and a steering nut are arranged on the inside of the housing. One side of the steering nut is provided with a left hydraulic chamber, the other side of the steering nut is provided with a right hydraulic chamber, and a rocker shaft is provided at the inner bottom of the housing, and the rocker shaft Cooperating with the steering nut, an electromagnetic proportional valve and an adjustment channel are provided at the bottom of the housing, and the adjustment channel communicates with the left hydraulic chamber. When the car computer detects that the speed of the vehicle exceeds a preset value, such as 40 km / h, the electromagnetic proportional valve is activated, so that the high-pressure oil in the left hydraulic chamber is unloaded through the adjustment channel. At this time, the user needs more The steering stroke and steering force can be completed to complete the steering, avoiding the loss of control of the vehicle caused by excessive steering, and effectively improving the safety of vehicle steering.
Description
technical field [0001] The invention relates to an automobile steering device, more precisely, an electro-hydraulic valve-controlled steering gear capable of changing the steering feel. Background technique [0002] The electro-hydraulic valve-controlled steering gear is a common automobile steering device. The relative rotation is realized by the steel ball arranged between the steering screw and the steering nut, thereby driving the sector gear on the steering arm to rotate, thereby realizing steering. When the vehicle is running at high speed, if the steering gear reacts too sensitively or turns too fast, it is easy to cause the vehicle to lose control and affect the safety of the vehicle. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing an electro-hydraulic valve-controlled steering gear that can change the steering feel. [0004] Above-mentioned technical problem of the present inventio...
