Description

Technical Field

[0001] The utility model relates to the field of new energy vehicle maintenance, in particular to a new energy vehicle wheel replacement device. Background Art

[0002] Wheels are circular elastic rubber products that roll on the ground and are assembled on various vehicles or machines. Their main function is to support the entire weight of the vehicle, bear the load of the car, ensure the adhesion between the wheel and the road, reduce and absorb the vibration and impact of the car when driving, etc. They are subjected to various deformations, loads, forces, and high and low temperature effects when driving, so they must have high load-bearing performance, traction performance, and buffering performance. They are also required to have high wear resistance and flexibility resistance, as well as low rolling resistance and heat generation.

[0003] However, when a wheel is damaged on the road, the driver can usually replace the spare tire by using the on-board jack. When using the wheel replacement device, the car must first be jacked up by the jack to facilitate personnel to disassemble the damaged wheel. When replacing a new wheel, the tire of some models is larger, and the overall mass of the wheel hub and tire is heavier and the volume is also larger. The user lifts the wheel to one end of the car drive shaft alone and makes the replaced wheel hub correspond to the mounting hole of the drive shaft one by one. Sometimes it may be necessary to repeatedly adjust up and down for many times. The driver consumes a lot of physical strength in this process, which brings inconvenience to the replacement.
