Embodiment Construction
[0020] Below in conjunction with accompanying drawing, the present invention will be further described.
[0021] Such as Figure 1-9 Shown, the assembly diagram of the present invention and the assembly diagram and the sectional view of the control end and the execution end of the present invention. The driver turns the steering wheel to generate steering torque on the transmission shaft 6, and the steering torque is transmitted to the screw shaft 7 through the connecting shaft system, and the screw shaft 7 rotates around the axis, and the shaft sleeve piston part is driven to move linearly along the axial direction by the circulating ball mechanism at the control end , so that the pressure liquid in the right cylinder chamber of the control end and the left cylinder chamber of the control end is respectively exchanged and flowed with the pressure liquid in the right cylinder chamber of the execution end and the left cylinder chamber of the execution end through the flow contr...

The invention relates to an automobile steering-by-wire system for achieving aligning and road feel based on fluid power. The automobile steering-by-wire system comprises a steering manipulation assembly, a steering executing assembly, a hydraulic valve device and an electronic control system. The steering manipulation assembly comprises a control end shell assembly, a drive shaft system and a shaft sleeve piston part. The steering executing assembly comprises an executing end shell assembly, a steering shaft, a drive device and a power assisting motor (12). The hydraulic valve device comprises a flow control valve (21) and a hydraulic pipe system. The electronic control system comprises a main controller (22) and an angle sensor system. The automobile steering-by-wire system has the advantages of being high in reliability, simple in structure and capable of adjusting aligning intensity in real time according to moving states of an automobile.
Description
technical field [0001] The invention relates to an automobile steering system, in particular to an automobile hydraulic-by-wire steering system, which belongs to the field of motor vehicle power-driven steering mechanisms. Background technique [0002] Automobile steering systems are roughly divided into manual steering systems, power steering systems, and steering-by-wire systems. The manual steering system is a scheme that uses a single mechanical transmission mechanism to transmit the steering torque of the driver to the wheels, and then transmits the centering torque of the wheels to the driver. Due to the use of a single mechanical transmission, the structure size and weight of this system All are larger, the structure is more complex, and the probability of mechanical failure is higher. The steer-by-wire system is a system that replaces a single mechanical transmission mechanism with components such as a central processing unit, sensors, integrated circuits, and cable...
