Problems solved by technology

[0003] In the existing steering gear, the power transmission is realized through the meshing of the rack and pinion. After a long time of work, the meshing parts of the rack and pinion will be greatly worn, resulting in abnormal noise and affecting the driving experience. If it keeps increasing, it will transmit a large impact on the road surface and cause damage to the parts themselves, resulting in loss of steering function and affecting driving safety

Abstract

The invention discloses a steering gear, a clearance adjusting mechanism of the steering gear and a vehicle. The steering gear comprises a steering input shaft and a rack meshed with the steering input shaft. The clearance adjusting device comprises an adjusting block, a spring, a transmission wheel, a sensor, a driving component and a controller, wherein the spring presses the adjusting block tightly on the rack, the transmission wheel is arranged at one end, far away from the adjusting block, of the spring, the sensor is arranged between the transmission wheel and the spring and is used for detecting the pressing force between the steering input shaft and the rack, the driving component is matched with the transmission wheel to drive the transmission wheel to move, and the controller receives detecting information of the sensor and controls the driving component to drive the transmission wheel. According to the clearance adjusting mechanism, the meshing clearance between the steering input shaft and the rack is accurately controlled by detecting the pressing force through the sensor, the abnormal sound and the part damage caused by the enlargement of the meshing clearance are avoided, and thus the steering performance, the reliability and the durability of the steering gear are ensued.

Description

technical field [0001] The invention relates to the field of vehicle manufacturing, in particular to a gap adjusting device for a steering gear, a steering gear with the gap adjusting device, and a vehicle with the steering gear. Background technique [0002] In the vehicle, the steering gear plays the role of transmitting torque in the steering system. Through the cooperation of the rack and pinion, the input force of the driver is converted into the axial force for realizing the steering function of the vehicle. [0003] In the existing steering gear, the power transmission is realized through the meshing of the rack and pinion. After a long time of work, the meshing parts of the rack and pinion will be greatly worn, resulting in abnormal noise and affecting the driving experience. If it keeps increasing, it will transmit a large impact on the road surface and cause damage to the parts themselves, resulting in loss of steering function and affecting driving safety. Conte...
