Embodiment Construction

[0011] An adjustment mechanism that can improve the friction performance and abnormal noise of the steering gear, which consists of a main body shell 1, a gear shaft fixed bearing 2, a gear shaft 3, a rack 4, a rack support base 5, a rack support spring 6, and a screw plug 7. Friction block 8, friction block spring 9, friction adjustment screw 10, screw plug cover rubber plug 11, rubber gasket 12, roller support pin 13 and rack support roller 14, the main body shell 1 is fixed by the gear shaft The bearing 2 is fixed with a gear shaft 3 , the gear shaft 3 is fixed relative to the main body shell 1 , the gear shaft 3 is engaged with a rack 4 , and the rack 4 floats relative to the main body shell 1 . The back of rack 4 is designed as a V-shaped support surface. One side of rack 4 is fixed with a rack support base 5 by screw plug 7, rack support spring 6 and rubber gasket 12, and one side of rack support base 5 is designed to match the V-shaped support surface of rack 4. Consis...

Abstract

The invention relates to a steering mechanism capable of improving friction performance and abnormal sound, belonging to the technical field of vehicle steering. The steering mechanism consists of body shell, a gear shaft, a rack, a rack support base, a friction block, a rack support roller, and the like; wherein the body shell is externally provided with the gear shaft; the gear shaft is engaged with the rack; the back of the rack is designed to be a V-shaped support surface; one side of the rack support roller is designed to a V-shaped surface which is accordant with the back of the rack; and the V-shaped surface is provided with the rack support roller. When a steering gear works, by using the characteristic that the rolling frictional resistance is less than the sliding frictional resistance, the steering mechanism leads the back of the rack is supported by the roller on the rack support base, so that the friction of the rack is not affected by the steering of a plug screw and the positive pressure of a rack support spring. The steering mechanism can effectively separately the steering for controlling a gap from the steering for controlling the friction, so that the problems such as the abnormal sound, the quality and the product performance, which are caused by the gap of the steering mechanism after assembly, can be effectively controlled to respectively steer the gas and the friction.

Description

Technical field: [0001] The invention relates to an adjustment mechanism capable of improving the friction performance and abnormal noise of a steering gear, belonging to the technical field of automobile steering. Background technique: [0002] When the car is running normally, turning left, turning right, and driving straight are the three most common basic movements of the car. In order to ensure the smooth running of the car, there is a set of mechanisms between the steering wheels of the car to complete the driving track of the car. This set of mechanisms that complete the flexible change of the driving direction of the car is called the steering system of the car. It is connected to the steering wheel of the car cab in a rigid or flexible way. , directly controlled by the driver. [0003] At present, the quality problems of the rack and pinion steering gear are largely reflected in abnormal noise or poor alignment. The clearance value is a very sensitive technical par...
