Problems solved by technology

Therefore, the left-right symmetrical change law of the traditional automobile steering gear transmission ratio cannot satisfy the characteristics of the difference in the driver's physiological and psychological perception experience.
In addition, the transmission ratio of the traditional steering gear is changed through the metal structure. In the actual operation, there is too much vibration and noise, and the driver feels discomfort such as frustration and discontinuity when steering.

Abstract

The invention discloses a low-noise automobile steering gear in the field of steering gear technology, which takes into account the driver's experience and handling performance, meets the requirements of multiple working conditions for automobile steering, takes into account both the driver's experience and the handling performance of the automobile, and reduces the noise in the steering process of the automobile. vibration and noise. Including the steering gear housing, the steering gear and the steering rack are installed in the steering gear housing, and the meshing teeth on the steering rack have a variety of different pitches; when the car turns to both sides, The tooth pitch distribution of the meshing teeth of the steering rack meshing with the steering gear in turn is asymmetrical; the steering rack is disconnected in the non-meshing area and connected by a rubber composite connector; the steering gear housing is equipped with a rubber composite pressure block The rubber composite pressing block is slidingly connected to the steering rack, and the rubber composite pressing block and the steering gear are respectively located on two sides of the steering rack and opposite to each other.

Description

technical field [0001] The invention belongs to the technical field of steering gears, and in particular relates to a low-noise automobile steering gear which takes both driver experience and handling performance into consideration. Background technique [0002] The steering gear is a very important assembly in the car, and the driver controls the steering of the car by manipulating the steering gear. There are many structural forms of automobile steering gears, and the commonly used ones are recirculating ball steering gears and rack and pinion steering gears. Due to its simple and compact structure, high transmission efficiency, and small footprint, the rack and pinion steering gear is widely used in passenger cars and trucks and passenger cars with small loads and independent suspensions on the front wheels. The performance of the steering gear is related to the steering portability, sensitivity, handling stability, maneuverability, and driving safety of the car. During ...
