Problems solved by technology

When we remove the tire, because there is still a certain interference fit between the wheel hub where the tire is located and the wheel axle of the car, it is necessary to separate it from the wheel axle while shaking it left and right when removing the tire. In the process of shaking out the wheel hub , the mounting hole of the wheel hub will cause friction with the wheel shaft, which will cause the mounting thread at the end of the wheel shaft to be worn to varying degrees, resulting in inconvenient butt joint of the lock nut when installing the new tire

Abstract

The invention provides a new energy vehicle tire replacement device and relates to the technical field of new energy vehicles. The replacement device includes a car chassis top holder and a bottom elevating frame. The bottom elevating frame includes a base and first hinged plates respectively hinged at both ends of the base. A trigger lever is hinged in the side wall cavity of each first hinged plate. Two triggers The top ends of the rods are protrudingly provided with a trigger block, and the automobile chassis jacking frame includes a top seat and a second hinged plate respectively hinged at both ends of the top seat, and the bottom ends of the two second hinged plates are respectively hinged to the ends of the two first hinged plates. At the top, a longitudinal tube is welded in the center of the bottom surface of the top seat. The invention can smoothly disengage the wheel hub from the wheel shaft without easily damaging the threads.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a tire replacement device for new energy vehicles. Background technique [0002] When changing the tires of new energy vehicles, it is necessary to place the lifting frame between the chassis of the car and the ground first, and lift the lifting frame upwards by rotating the screw mechanism, so as to lift the chassis of the car to a certain height, and then place the wheel hub and the axle Remove the bolts between the tires, and then remove the tires together with the hubs, and finally fix the new tires on the axles to complete the removal and replacement of the car tires. When we remove the tire, because there is still a certain interference fit between the wheel hub where the tire is located and the wheel axle of the car, it is necessary to separate it from the wheel axle while shaking it left and right when removing the tire. In the process of shaking out the wheel...
