TECHNICAL FIELD
[0001] The utility model relates to the technical field of automobile parts, in particular to a disconnecting type axle suspension assembly. BACKGROUND
[0002] Suspension is the general term of all force transmission connecting devices between the frame (or load-bearing body) and axle (or wheel) of the automobile, which transmits the force and torque between the wheel and frame, buffers the impact force from the uneven road to the frame or body, and reduces the vibration caused thereby to ensure the smooth driving of the automobile. The axle (also known as axle) of the automobile is connected with the frame (or load-bearing body) through the suspension, and the wheels are installed at both ends of the axle. The axle functions to bear the load of the automobile and maintain the normal driving of the automobile on the road. The axle can be integral, like a huge barbell, which supports the body through the suspension system at both ends, so the integral axle is usually matched with the non-independent suspension. The axle can also be disconnecting, like two umbrellas inserted into the body on both sides, which supports the body through the suspension system respectively, so the disconnecting axle is matched with the independent suspension.
[0003] The cooperation of the axle and suspension of the automobile controls the driving steering of the vehicle. In the long-term use process of the vehicle, the suspension continuously cooperates to attenuate the vibration caused by the uneven road in the driving process of the vehicle. In the long-term use process of the suspension, the energy-absorbing damping piece that is sleeved with each other is continuously worn in the process of friction, which causes the sleeving surface to be gradually smooth, affects the shock-absorbing capacity of the suspension, and affects the driving experience of the driver. The replacement of the whole axle is relatively cumbersome. Therefore, the utility model provides a disconnecting type axle suspension assembly. CONTENT OF THE UTILITY MODEL
