Problems solved by technology
[0004] The present invention mainly aims at the problem that adding a shock absorber in the steering wheel will increase the weight of the steering wheel itself and increase the cost, and provides a method that can adjust the modal frequency of the entire steering mechanism without adding a shock absorber to avoid external excitation sources. Frequency, and thus the vibration-suppressing device on the steering mechanism

Embodiment Construction
[0019] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.
[0020] like figure 1 , 2 As shown, a device for suppressing vibration on a steering mechanism, the steering mechanism includes a steering wheel 1, a steering shaft 2 fixed below the steering wheel 1, a steering column tube 3 sleeved on the outside of the steering shaft 2, used to fix the steering column tube 3 Upper bracket 6 and lower bracket 4 on the vehicle body. The upper bracket 7 includes two "L"-shaped fixed frames 7-1 and a fixed body 7-2, and the two "L"-shaped fixed frames 7-1 are symmetrically located on both sides of the steering column tube 3 and oppositely arranged to ensure When the automobile vibrates, the force on the steering column tube 3 is balanced and the vibration transmission is uniform. The fixed body 7-2 is a hollow structure, one end of the fixed body 7-2 is an arc surface...

The invention relates to an automobile steering mechanism, in particular to a jitter suppressing device on the steering mechanism. The steering mechanism comprises a steering column pipe, wherein the steering column pipe is fixed on an automobile body through an upper bracket; the upper bracket comprises L-shaped fixing frames which are positioned on the two sides of the steering column pipe and are symmetrically arranged, and a fixing body which is positioned between the two fixing frames; the upper bracket is provided with a frequency modulation bracket and a locking mechanism for fixing the frequency modulation bracket; the frequency modulation bracket can slide up and down along the outer circumference of the steering column pipe; and the two sides of the frequency modulation bracket are in clearance fit with the fixing body along the width direction. The jitter suppressing device has the advantages that: a shock absorber is not required to be arranged, the modal frequency of the whole steering mechanism is adjusted to avoid the frequency of an external excitation source, the jitter of a steering wheel is suppressed, and the device is convenient to produce and assemble.
Description
technical field [0001] The invention relates to an automobile steering mechanism, in particular to a device used for suppressing vibration on the steering mechanism. Background technique [0002] When the car is running, the body will be affected by various excitation sources, such as: tire unbalanced dynamic force, road excitation, engine, etc., and the body will transmit the vibration generated by the excitation source to the steering wheel, and the steering wheel acts as The most sensitive part in the vibration of the steering system will cause the steering wheel to produce more serious vibration. Since the steering wheel is the part that the driver directly contacts, the vibration of the steering wheel is very important to the safety and comfort of driving. The modal frequency of the steering mechanism is the same as the frequency of the external excitation source, and the resonance is an important cause of steering wheel vibration. Therefore, solving the resonance of ...
