Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Referring to fig. 1 and 2, an embodiment of the present invention provides a suspension system, which is at least partially disposed in a rim of a wheel 10, the suspension system includes a knuckle 11, a damper assembly 12, and a flexible bushing 13, the knuckle 11 is rotatably connected to the wheel 10, and the flexible bushing 13 is disposed between the damper assembly 12 and the knuckle 11.

In particular, suspension systems are commonly used to couple axles to a vehicle body or frame as a component in vehicles that provides a damping effect to dampen the impact vibrations generated by the wheels of the vehicle when the vehicle is driven over a bumpy surface. The wheel is used as a component in a running mechanism of a vehicle, the wheel mainly comprises a rim, a hub and a spoke for connecting the rim and the hub, in the existing wheel, the rim is used for installing a bearing tire, the hub is arranged at the center of an annular rim and is used for connecting an axle, and no part is arranged in a space area between the rim and the hub in the wheel, so that the inside of the rim is a space area surrounding the hub, the outer side of the space area (namely, the side of the wheel far away from the connecting line of the front center and the rear center of a vehicle body after the wheel is assembled with the vehicle body) is connected with the hub through the spoke, and the inner side (namely, the side of the wheel close to the connecting line of the front center and the. It will be understood that a plane is formed by the spokes at the outer edge of the rim (the outer edge being understood with reference to the outside of the aforementioned spatial region), i.e. the space within the rim which is defined by this plane and the circumferential surface defined by the rim. As shown in fig. 1, in the embodiment of the present invention, it is found that the suspension system can be at least partially placed inside the rim by reducing the size of the suspension system through the study of the space inside the rim, that is, the suspension system is fixed in the space defined by the spoke plane and the rim circumferential surface.

As shown in fig. 1 and 2, a suspension system of an embodiment of the present invention may include a knuckle 11, a shock absorber assembly 12, and a flexible bushing 13. It should be noted that, in the conventional vehicle, the knuckle 11 is rotatably connected to a wheel, the hub can be inserted into a rotating shaft of the knuckle 11, the wheel can rotate relative to the knuckle 11, and the knuckle 11 also provides a connection point for a steering rod, and after being connected to the steering rod, the connection point is used for receiving a driving force input from a steering gear to steer the wheel. In the present embodiment, the knuckle 11 is rotatably connected to the wheel 10, and provides a mounting connection structure for the damper assembly 12. For example, the knuckle 11 is rotatably coupled to the hub of the wheel 10, and the knuckle 11 and the wheel 10 can move synchronously when the wheel 10 rolls and rolls along the road. The damper assembly 12 is flexibly connected to the knuckle 11 via a flexible bushing 13, and horizontal vibrations between the knuckle 11 and the damper assembly 12 can be at least damped via the flexible bushing 13. The flexible bushing 13 may be a rubber bushing. When the knuckle 11 and the wheel 10 vibrate simultaneously, a part of energy generated by the horizontal vibration may be absorbed by the flexible bush 13, thereby attenuating the horizontal vibration of the shock absorber assembly 12 connected to the knuckle 11.

Further, it is understood that the maximum size of the knuckle 11 and the shock absorber assembly 12 described above does not exceed the inner ring diameter of the rim in the radial direction of the wheel 10, and thus both the knuckle 11 and the shock absorber assembly 12 can be disposed inside the rim. At least some of the above-described knuckle 11, shock absorber assembly 12, and flexible bush 13 are located in a space within the rim in the axial direction of the wheel 10, and the remaining components may extend from the space within the rim in the case where the space within the rim is compact. Illustratively, if the knuckle 11 and the flexible bushing 13 can be disposed in a space within the rim, the damper assembly 12 is connected to the knuckle 11 and extends out of the space within the rim. The embodiment of the utility model provides a, through setting up suspension system in the rim of wheel, idle space in can the make full use of rim to occupy too much space when avoiding suspension system to be in automobile body or frame below, be favorable to expanding the spare part layout space of automobile body or frame below. And the shock absorber subassembly of suspension system has realized through flexible bush and knuckle with the flexible connection of wheel, can further weaken the horizontal vibration between wheel and the suspension system, promotes the riding comfort.

The strut assembly 122 is connected to the knuckle 11 via the aforementioned flexible bushing 13, and in the vehicle body type, the upper seat assembly 121 is used for being fixedly connected to the vehicle body, and in the vehicle body type, the upper seat assembly 121 is used for being fixedly connected to the vehicle frame. In practical applications, the upper seat assembly 121 may be provided with a connecting hole for fixedly connecting the vehicle body or the vehicle frame with the upper seat assembly 121 through a bolt. Therefore, when the weight of the vehicle body or the vehicle frame acts on the upper support assembly 121 to cause the relative movement between the upper support assembly 121 and the pillar assembly 122, the elastic member 123 may deform to absorb energy. On the contrary, when the road surface impacts, the wheel 10 drives the knuckle 11 to move, and the pillar assembly 122 moves relative to the upper seat assembly 121, the elastic member 123 may deform to absorb energy. Therefore, the vibration damper assembly described above can achieve vibration isolation using the elastic member 123 installed in the rim, while attenuating horizontal vibration using the flexible bush 13 provided between the strut assembly 122 and the knuckle 11, to avoid horizontal vibration of the entire vibration damper assembly caused by the horizontal vibration.
