Abstract

The invention relates to a noise and vibration reduction device for a steering system, a car including the device and a noise and vibration reduction method for the system. The device is arranged on a hydraulic steering system. The device comprises a vibration sensor, a control unit and a steering oil tube valve. The vibration sensor is arranged on a steering high-pressure oil tube of the hydraulic steering system to detection the vibration situation of the steering high-pressure oil tube. The control unit is electrically connected with the vibration sensor which sends detected vibration signals to the control unit. A steering oil tube valve is arranged on the steering high-pressure oil tube and is electrically connected with the control unit which controls the steering oil tube valve to change the oil passing section size according to the vibration signals, and accordingly, the steering liquid flowing speed is changed, and the liquid flow frequency is changed.

Description

technical field [0001] The invention relates to a noise reduction and vibration reduction device in the field of automobiles, in particular to a noise reduction and vibration reduction device for a steering system. Background technique [0002] The hydraulic steering system of the car uses the steering force generated by the steering fluid to reduce the driver's hand control force, ensure driving safety, and make the car more comfortable to drive and easier to turn. see figure 1 Shown is the structural schematic diagram of the existing hydraulic steering system. Existing hydraulic steering system is mainly made up of steering oil tank 1, steering high-pressure oil pipe 2, steering gear 3, steering oil pump 4, steering column 5 and steering wheel 6, wherein a noise reduction bar is installed inside steering high-pressure oil pipe 2. When the steering fluid flows in the steering system, when the frequency of the fluid flow is the same as that of the steering oil pipe, resona...
