Description
Technical Field
The utility model belongs to the technical field of the steering column technique of car and specifically relates to a take steering column of vibration/noise reduction function is related to.
Background
At present, a vehicle with a turnable vehicle head has a long section of sliding spline group in a steering column, and a gap between an inner spline and an outer spline of the sliding spline group cannot be avoided. Because of the existence of the gap, the inner spline and the outer spline can move relatively, so that the inner spline and the outer spline can be knocked when external force is applied to the inner spline and the outer spline, when the external force is large enough, knocking can generate vibration and sound which can be perceived by people, and continuous external force with a certain specific frequency can enable knocking to continuously occur to cause resonance.
When a vehicle passes through an uneven road area, the generated vibration is transmitted to the steering column through the steering engine by the vehicle frame, if the frequency of the vibration is close to the natural frequency of the vibration of the internal spline and the external spline of the steering column, the sliding spline set of the steering column resonates, the generated vibration is transmitted to the steering wheel along the steering column shafting, and the steering wheel can be felt by hand or hear sound.
Moreover, when the automobile runs on an uneven road surface, the vibration is difficult to avoid due to the structure of the steering column of the automobile with the automobile head capable of being turned over.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model aims to solve the technical problem that a take steering column of vibration/noise reduction function is provided, its vibration/noise reduction effect is good, has improved the drive sense organ quality.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
this take steering column of vibration/noise reduction function closes the piece and establishes the steering column slip spline assembly in steering column upper portion closes piece lower part including steering column upper portion, steering column slip spline assembly still includes the elastic component that is used for vibration/noise reduction including matched with steering column slip internal spline axle and steering column slip spline housing, the elastic component is established between steering column slip internal spline axle and steering column slip spline housing.
Further:
the elastic piece is a damping spring, and the damping spring is arranged in the steering column sliding spline sleeve.
The damping spring is arranged at the bottom of the steering column sliding spline sleeve, and one end part of the damping spring is arranged corresponding to the inner end of the steering column sliding internal spline shaft.
