Abstract

The utility model discloses a kind of vibration damping wheel hub, including wheel rim, the hub body being positioned at wheel rim center and the spoke being uniformly arranged between wheel rim and hub body, described spoke includes hydraulic cylinder, the piston rod of hydraulic cylinder is connected with the inner side of wheel rim, the cylinder body of hydraulic cylinder is connected with the outside of hub body, and described spoke also includes the connector of elastically deformable, and connector is disposed between hydraulic cylinder, one end of connector is connected with the inner side of wheel rim, and the other end is connected with the outside of hub body.On the basis of the rigid spoke of conventional boss is replaced by flexible hydraulic cylinder pressure by the utility model, it is additionally arranged the connector of elastically deformable as spoke, the dilatation being constantly alternately produced by connector, jointly act on the impact forces to wheel hub for the counteracting road surface with hydraulic cylinder, thus damping effect is played further to wheel hub, improve the resistance to shock of wheel hub.

Description

A kind of vibration damping wheel hub
Technical field
The utility model relates to wheel parts, is specifically related to a kind of wheel hub.
Background technology
Generally, the most important safety component that wheel hub carries as vehicle, it is subjected to light weight perpendicular acting and arrives Pressure on wheel hub, is also turned by dynamic torque active force when vehicle launch or braking and vehicle travel process, meets The dynamic alternate stress of the different directions such as the impact to concave-convex road surface or by road obstacle.This requires that wheel hub has preferably Fatigue strength and higher rigidity, but thing followed problem is, the vibration resistance of wheel hub correspondingly reduces, when vehicle travels There will be and significantly jolt, cause the NVH performance of vehicle to reduce, even cause traffic accident.CN 203945899 U discloses one Vibration damping wheel hub, including cylindrical wheel hub and center hub, is connected by piston rod between described cylindrical wheel hub and center hub, piston Bar has the effect of telescopic adjustment, and described piston rod includes fixing bar and motion bar, and described fixing bar is fixed in center hub, Described motion bar is fixed on cylindrical wheel hub, and described motion bar is provided with spring, and motion bar is arranged at spring inner, described both Arranging for concentric circles, described spring is inconsistent with cylindrical wheel hub and fixing bar.Above-mentioned technology can improve the vibration resistance of wheel hub Can, but also further improved necessity.
Content of the invention
The purpose of this utility model is to provide a kind of vibration damping wheel hub, to improve the resistance to shock of wheel hub.
Vibration damping wheel hub described in the utility model, including wheel rim, be positioned at the hub body at wheel rim center and be uniformly arranged on Spoke between wheel rim and hub body, described spoke includes hydraulic cylinder, and the piston rod of hydraulic cylinder is connected with the inner side of wheel rim, liquid The cylinder body of cylinder pressure is connected with the outside of hub body, and described spoke also includes the connector of elastically deformable, and connector interval sets Putting between hydraulic cylinder, one end of connector is connected with the inner side of wheel rim, and the other end is connected with the outside of hub body.
Further, described connector is curved long strip block.
Further, the middle part of described connector distorts in twisted shape.
Vehicle in the process of moving, is positioned at the hydraulic cylinder of wheel hub bottom and connector by compression stress, and will be positioned at wheel hub The hydraulic cylinder on top and connector will be stretched power, make hydraulic cylinder constantly be alternately produced telescopic variation, and connector constantly replaces Produce dilatation, thus to a certain degree counteract the impact forces to wheel hub for the road surface.
On the basis of the rigid spoke of conventional boss is replaced by flexible hydraulic cylinder pressure by the utility model, being additionally arranged can elastic shape The connector becoming, as spoke, the dilatation being constantly alternately produced by connector, jointly acts on counteracting road surface with hydraulic cylinder Impact forces to wheel hub, thus damping effect is played further to wheel hub, improve the resistance to shock of wheel hub.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model vibration damping view.
Fig. 3 is the structural representation of connector.
In figure: 1-wheel rim, 2-hydraulic cylinder, 3-connector, 4-hub body.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
See a kind of vibration damping wheel hub shown in Fig. 1 and Fig. 2, including the 1st, wheel rim is positioned at the hub body 4 and all at wheel rim center The even spoke being arranged between wheel rim 1 and hub body 4, described spoke includes hydraulic cylinder 2 and is capable of the company of elasticity of flexure deformation Fitting 3, described connector 3 is curved long strip block, and it is disposed between hydraulic cylinder 2, the piston rod of described hydraulic cylinder 2 All be connected with the inner side of wheel rim 1 with one end of connector 3, the cylinder body of hydraulic cylinder 2 and the other end of connector 3 all with hub body The outside of 4 connects.
In the present embodiment, as it is shown on figure 3, on the premise of the elasticity of flexure performance of connector 3 meets demand, by connector The middle part of 3 distorts in twisted shape, by increasing capacitance it is possible to increase the strength and stiffness of connector 3, improves the service life of wheel hub.
Vehicle in the process of moving, is positioned at the hydraulic cylinder 2 of wheel hub bottom and connector 3 by compression stress, and is positioned at wheel hub The hydraulic cylinder 2 on top and connector 3 are stretched power, and the hydraulic cylinder 2 in wheel rolling makes wheel hub is constantly alternately produced flexible Change, connector 3 is constantly alternately produced dilatation, thus counteracts the impact forces to wheel hub for the road surface to a certain extent, Improve the resistance to shock of wheel hub.
