Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0041] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0042] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention belongs to the technical field of automobile control, and discloses a steering wheel vibration frequency adjusting device and method. The steering wheel vibration frequency adjusting device comprises a fixed base, an adjusting mechanism and a balance weight mechanism, a connecting piece is fixedly connected between the balance weight mechanism and the fixed base, the adjusting mechanism is installed between the balance weight mechanism and the fixed base, and a driving mechanism is installed on the balance weight mechanism. Compared with the prior art that the vibration frequency of the steering wheel is adjusted by manually adjusting a balancing weight, the adjusting mechanism is installed between the balancing weight mechanism and the fixed base, the vibration frequency of the steering wheel is adjusted through the adjusting mechanism, and therefore the vibration frequency device of the steering wheel is rapidly adjusted; the efficiency and the accuracy of adjusting the vibration frequency of the steering wheel are improved.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a device and method for adjusting the vibration frequency of a steering wheel. Background technique [0002] Steering wheel vibration is a common vibration problem caused by powertrain excitation or chassis input excitation in the process of automobile development. Since the vibration of the steering wheel can allow customers to feel the quality of the vehicle most intuitively, it often causes relatively large complaints from customers. Therefore, vehicle development It is necessary to solve the problem of steering wheel vibration. Due to the difficulty and cost of powertrain input countermeasures, steering wheel dynamic shock absorbers are commonly used steering wheel vibration countermeasures. The current dynamic vibration absorber is generally installed inside the parts of the car, and the adjustment of the frequency of the dynamic vibration absorber can only be do...
