Problems solved by technology
[0005] However, in the existing hydraulic power steering device, when the piston connected to the rack reciprocates left and right in the cylinder barrel with the help of the hydraulic pressure of the working fluid when the driver turns the steering wheel, the working fluid will flow on the piston. Leakage between the cylinder barrel and the left and right cylinders causes the working fluid to be continuously output from the hydraulic pump
[0006] In addition, if the auxiliary steering force cannot be provided due to the leakage of the working fluid when the driver turns the steering wheel, the driver needs to apply a strong or particularly weak force to the steering wheel, which leads to the existing hydraulic pressure. The booster device is easy to leak and the device fails

A steering assist device for vehicles is applied to a vehicular steering gear. The steering gear comprises a steering wheel and a steering shaft. The steering wheel fixed to one end of the steering shaft is provided with an angle detector which is connected to a control unit so as to detect rotational angle of the steering wheel in real time. The steering assist device for vehicles comprises a housing and a screw. A transmission wheel is disposed inside the housing, and the steering shaft passes the transmission wheel and is fixed to the transmission wheel through a pin. One end of the screw is supported to the housing through a rear bearing element, and the other end of the screw is supported to the housing through a front bearing element and extends out of the front bearing element; the extending end of the screw is connected to a drive unit through a coupling. The drive unit is connected to the control unit so as to receive control signals. The steering assist device is simple in structure and convenient to mount and demount, and is capable of providing steering assistance stably; therefore, the defects of the prior art are overcome.
Description
technical field [0001] The invention relates to the technical field of vehicle accessories, in particular to a vehicle steering assist device. Background technique [0002] In vehicle accessories, the steering device is a device that is arranged between the driver's seat and the wheel so that the driver can move the angle of the wheel. The steering device includes a steering shaft arranged under the driver's steering wheel, a gear valve assembly connected to the steering shaft, and extending to the left and right sides and connected to the wheels for directly turning the wheels during the action of the gear valve assembly a toothed rod. [0003] Existing vehicle steering devices, especially high-end vehicles, are equipped with power steering devices, which usually use hydraulic pressure to perform power steering. Commonly used power steering devices may include a hydraulic pump and a gear valve assembly connected to the hydraulic pump. The gear valve assembly is arranged u...
