Suspension structure is the general term for all force transmission connection devices between the frame and the axle or wheels in the vehicle. Its function is to transmit the force and moment between the wheels and the frame, and buffer the impact transmitted to the frame or body due to uneven roads. force, and attenuate the vibration caused by it, so as to ensure that the vehicle can run smoothly. The quality of the suspension structure directly affects the handling stability, braking safety and comfort of the four-wheel electric vehicle.

However, the suspension structure of the traditional four-wheel electric vehicle adopts a non-independent front axle to connect with the vehicle frame, so that when the vehicle is walking, the range of the wheels bouncing up and down is not large. On bumpy roads, the comfort is poor, and rollover is more likely to occur when turning. In addition, the suspension structure of the traditional four-wheel electric vehicle is not only complicated in structure, but also takes up a lot of space. The lower end of the shock absorber is directly connected to the wheel. Well, it is more difficult to assemble.

Detailed ways

In order to be able to further understand the features, technical means and achieved specific objectives and functions of the utility model, and to analyze the advantages and spirit of the utility model, a further understanding of the utility model can be obtained through the following detailed description of the utility model in conjunction with the accompanying drawings and specific embodiments .

The utility model includes a vehicle frame 100 , the vehicle frame 100 is fixedly connected with a support frame 200 , and the support frame 200 is connected with a shock absorber 300 . One end of the shock absorber 300 is provided with a first shock absorber rotating shaft 310, and the other end of the shock absorber 300 is provided with a second shock absorber rotating shaft 320, and the first shock absorber rotating shaft 310 is connected to the support The frame 200, the second shock absorber rotating shaft 320 is connected with a rocker arm 400. One end of the shock absorber 300 is movably connected to the support frame 200 through the first shock absorber rotating shaft 310, and the shock absorber 300 can surround the connection with the support frame 200 through the first shock absorber rotating shaft. turn around. The other end of the shock absorber 300 is movably connected with the rocker arm 400 through the second shock absorber rotating shaft 320 . The first shock absorber rotating shaft 310 and the second shock absorber rotating shaft 320 make the shock absorber 300 respond more sensitively when absorbing shocks, and the shock absorbing effect is better.

One end of the rocker arm 400 is movably connected to the second shock absorber shaft 320 , and the other end of the rocker arm 400 is connected to the support frame 200 . One end of the rocker arm 400 connected to the support frame 200 is provided with a first bushing 410 , and the support frame 200 is provided with a round rod 210 matching the first bushing 410 . The first bushing 410 is sheathed on the periphery of the round rod 210 , and the rocker arm 400 is movably connected to the round rod 210 through the first bushing 410 . The first sleeve 410 can rotate along the round rod 210 , thereby driving the rocker arm 400 to swing.

One end of the rocker arm 400 connected to the second shock absorber shaft 320 is provided with a second sleeve 420 . The second bushing 420 is sheathed on the periphery of the second shock absorber shaft 320 , and the rocker arm 400 rotates along the second shock absorber shaft 320 through the second bushing 420 .

The shock absorber 300 is sheathed with a spring 330 , and the spring 330 is used to control the movement of the shock absorber 300 and alleviate the vibration and impact caused by the uneven road surface.

The shock absorber 300 is also connected with a connecting piece 500, and the connecting piece 500 is connected with the hub 600 of the wheel.

When using a four-wheel electric vehicle, when the wheels of the electric vehicle encounter vibrations generated by bumpy roads, the vibrations are first transmitted to the shock absorber 300 and the rocker arm 400 through the wheels of the electric vehicle and the connecting piece 500 . The spring 330 around the shock absorber 300 is elastically deformed under pressure, and the shock absorber 300 absorbs shock. At this time, since the rocker arm 400 is movably connected with the shock absorber 300 and the support frame 200, when the rocker arm 400 receives a shock, the rocker arm 400 passes through the first bushing 410 and the second The shaft sleeve 420 is rotatable, so that the vibration is weakened. At the same time, the shock absorber 300 transmits the remaining vibration to the vehicle frame 100 through the support frame 200. At this time, the vibration is extremely small, and the human body can hardly feel the vibration, thereby achieving the shock absorption effect and increasing the riding comfort. comfort.

In summary, the utility model has a simple structure and is easy to install, and the wheels on both sides are connected to the vehicle body through the shock absorber 300 and the support frame 200 independently of each other. When walking on a bumpy road, when one side of the wheel is impacted, the shock absorber 300 can absorb the impact, so that the impact will not spread to the other side of the wheel, so that the vehicle is always in good working condition, and the shock absorption effect is good , the ride is comfortable.
