Problems solved by technology

[0003] Nowadays, in the process of changing the tires of the "old driver", because the wheel hub and the brake disc are fixed together for a long time, and under the action of lubricating oil or anti-rust oil, there is no gap between the two, even if the nut is removed Finally, it is still difficult for the user to loosen the tire. At this time, the "veteran driver" will hold the body with both hands and kick hard against the side of the tire to loosen the tire. However, this method will cause damage to the wheel hub and the brake disc. The bolts on the tire are worn and bumped, and unloading the tire many times in this way will cause irreparable damage to the hub. Therefore, we propose a tire replacement device for new energy vehicles

Abstract

The invention discloses a tire changing device for new energy vehicles, relates to the technical field of tire changing devices for automobiles, solves the problem of inconvenient loosening of tires and brake discs, and includes a bearing seat, two sets of support arms are embedded in the upper end of the bearing seat , the inner side of the support arm 1 is fixedly installed with a connecting bolt, and the connecting bolt is movably embedded in the inner side of the bearing seat. Through the cooperation of the compression mechanism and the reinforcement mechanism in the present invention, when the user jacks up the car, the movement of the two sets of connecting blocks The two groups of pistons can squeeze the gas and compress the gas to the inside of the spherical bag. After the connecting port is sleeved on the bolt between the hub and the brake disc, the compressed gas is released instantly through the limiter to make the high-pressure air Impact on the connection between the wheel hub and the brake disc, the two can be separated, which is convenient and quick, and will not cause damage to the wheel hub. The friction and stability between the bearing seat and the ground can be improved.

Description

technical field [0001] The invention relates to the technical field of automobile tire changing devices, in particular to a tire changing device for new energy vehicles. Background technique [0002] The spare tire and the tools needed to replace the tire are placed in the trunk of the car. The tools are usually a jack and a wrench. When it needs to be replaced, the wrench removes the nut on the wheel hub, and then the car needs to be replaced by the jack. One end is jacked up, which is convenient for the user to change the tire. [0003] Nowadays, in the process of replacing the tires of "old drivers", because the hub and the brake disc are fixed together for a long time, and under the action of lubricating oil or anti-rust oil, there is no gap between the two, even if the nut is removed After that, it is still difficult for the user to loosen the tire. At this time, the "old driver" will hold the body with both hands and kick the side of the tire to loosen the tire, but t...
