Problems solved by technology

On the one hand, the braking system of electric vehicles has three types: disc brakes, drum brakes and wire brakes. Disc brakes and drum brakes are suitable for conventional electric vehicles. Wire brakes are generally suitable for small electric vehicles, but the performance of wire brakes is poor and the brakes are not reliable. , easy to fail, so it is necessary to develop a high-performance small electric wheel hub brake structure; on the other hand, the tires of small electric vehicles are generally solid and have poor elasticity, and they are prone to bumps when driving, making people uncomfortable when sitting

Embodiment Construction

[0009] The invention relates to a small electric wheel hub with electromagnetic brakes and hollow tires, such as figure 1 , figure 2 As shown, it includes a wheel hub 1 of a small electric vehicle, a tire is installed on the wheel hub, a rotating shaft 2 is arranged in the wheel hub, a spring plate 3 and a brake pad 4 are arranged on one side of the outer wall of the wheel hub 1, and on the rotating shaft 2 on the same side of the brake pad Set the coil shell 5, the coil 6 is set in the coil shell, the coil is connected to the electric vehicle controller through the wire, the friction plate 7 is set on the inner wall of the coil shell, when braking, the coil 6 is energized to generate a magnetic field, and through the elastic action of the spring plate 3, The brake pad 4 is adsorbed onto the friction pad 7 to brake the wheel hub. The main feature of this scheme is that a spring plate 3 and a brake pad 4 are set on one side of the hub 1, and a coil 6 and a friction plate 7 ar...

Abstract

The invention relates to a small-sized electric vehicle hub with an electromagnetic brake and a hollow tire. The small-sized electric vehicle hub comprises a small-sized electric vehicle hub body, thetire is arranged on the hub body, and a rotation shaft is arranged in the hub body; a spring sheet and a brake sheet are arranged on the outer wall of one side of the hub body, a coil shell is arranged on the rotation shaft at the same side of the brake sheet, and a coil is arranged in the coil shell; an electric vehicle controller is connected to the coil through a wire, a friction sheet is arranged on the inner side wall of the coil shell, during brake, the coil is powered on to generate a magnetic field, the brake sheet is attracted on the friction sheet through the elastic function of thespring sheet, and accordingly the hub body is braked. According to the small-sized electric vehicle hub, the magnetic field is generated through the coil, the brake sheet is attracted for braking accordingly, and the hub is good in performance and reliable in braking.

Description

technical field [0001] The invention relates to an electric wheel hub, in particular to a small electric wheel hub with electromagnetic brakes and hollow tires. Background technique [0002] Small electric wheel hub, the size is generally between Φ120mm - Φ200mm, suitable for small electric vehicles. On the one hand, the braking system of electric vehicles has three types: disc brakes, drum brakes and wire brakes. Disc brakes and drum brakes are suitable for conventional electric vehicles. Wire brakes are generally suitable for small electric vehicles, but the performance of wire brakes is poor and the brakes are not reliable. , easy to fail, so it is necessary to develop a high-performance small electric wheel hub brake structure; on the other hand, the tires of small electric vehicles are generally solid and have poor elasticity, and they are prone to bumps when driving, making people uncomfortable. Contents of the invention [0003] The purpose of the present invention...
