Problems solved by technology

But for the bench noise test, if the noise value of the load mechanism is too large, it will directly affect the test results of the steering gear, and even the noise of the load mechanism has completely covered the noise of the steering gear itself, making the experiment impossible

Embodiment Construction

[0019] Such as Figure 1 ~ Figure 2 An oil cylinder rack tension adjustment mechanism is shown, including a rack 1, a support seat 12, and an adjusting screw plug 13. The rack 1 is arranged axially through the oil cylinder 2, and one end of the rack 1 protrudes from the oil cylinder 2 and passes through the housing. 11. The rack 1 meshes with the gear shaft 4. One end of the support seat 12 is provided with a rack wrapping wall. The other end of the support seat 12 is connected to the adjustment screw plug 13 through a spring 14. The adjustment screw plug 13 is screwed to the housing 11 superior. The wrapping wall of the rack is an arc-shaped wall matching the shape of the outer wall of the rack 1, and the wrapping wall of the rack is a wrapping wall of polyoxymethylene resin. The end of the support seat 12 is provided with a groove, and the blocked end of the adjusting screw plug 13 and the groove form a spring cavity, and the spring 14 is arranged in the spring cavity. The...

Abstract

The invention discloses an adjustment mechanism and an adjustment method for the tightness of a rack of an oil cylinder. The adjustment mechanism comprises the rack, a supporting seat and an adjustment plug screw, wherein the rack penetrates through the oil cylinder in the axial direction; one end of the rack extends out of the oil cylinder and penetrates through a shell; the rack is engaged witha gear shaft; a rack wrapping wall is arranged at one end of the supporting seat; the other end of the supporting seat is connected with the adjustment plug screw through a spring; and the adjustmentplug screw is connected with the shell in a threaded mode. The adjustment mechanism and the adjustment method for the tightness of the rack of the oil cylinder have the advantages that small noise isgenerated in the use process, the requirements needed when an automobile steering device is subjected to a stand noise experiment are fully met, and the bidirectional damping function and stable loadsof the rack in the oil cylinder are realized.

Description

technical field [0001] The invention relates to the technical field of steering gear noise experiments, in particular to an oil cylinder rack tightness adjustment mechanism and an adjustment method thereof. Background technique [0002] Steering gear (or called steering gear) is a very important part in the steering system of a car. It converts the rotational movement of the steering wheel into the yaw movement of the tires, thereby realizing the steering function of the car. Automobile steering gear can be roughly divided into three categories according to the form of power assistance: mechanical steering gear, hydraulic power steering gear, and electric power steering gear. In today's society, especially in terms of passenger cars (family cars), the requirements for ride comfort are getting higher and higher, which includes the requirements for noise. Therefore, the corresponding noise evaluation will be carried out before the car is officially put into the market. As a...
