Suspension damping electric wheel

Abstract

The invention relates to a suspension damping electric wheel. The suspension damping electric wheel is characterized by comprising an inner steel ring; an inner bearing, an electromagnetic brake, a bearing gland, a hub motor stator, a hub motor rotor, a tire rim and a tire are arranged outside the inner steel ring; a suspension damper is arranged in the inner steel ring, a damping assembly comprises a shell, and a guide column lubrication sleeve, a guide sleeve, a damping spring and a guide column are arranged in the shell; the shell is connected with a suspension assembly through a linkage frame, and the suspension assembly comprises an upper end cover and a lower end cover; a guide rod and a suspension spring are arranged between the upper end cover and the lower end cover, a guide pipe and a guide rod lubrication pipe are arranged outside the guide rod, and a connecting shaft is arranged in a suspension base arranged on an electric car; the electromagnetic brake comprises the bearing gland, and an electromagnetic brake movable ring is arranged in the bearing gland; and an electromagnetic brake limiting guide column is arranged outside the inner steel ring, an elastic sealing ring is arranged between the electromagnetic brake limiting guide column and an electromagnetic brake stretching guide pipe, the electromagnetic brake stretching guide pipe is connected with an electromagnetic brake stretching fixing support, an electromagnet core and an electromagnet coil are arranged outside the electromagnetic brake stretching fixing support, and the electromagnet coil is connected with the hub motor stator.

Description

technical field [0001] The invention relates to a wheel of an electric vehicle, in particular to a suspension shock-absorbing electric wheel. Background technique [0002] In order to make the electric vehicle run smoothly, reduce bumps, and increase the stability of operation, spring shock absorbers are usually arranged on the vehicle frame of the electric vehicle, or suspension and shock absorber are installed simultaneously, but the prior art suspension and shock absorber Most of them are installed separately, the structure is complex, installation and disassembly are troublesome, maintenance is inconvenient, and the failure rate is high, the service life is short and other shortcomings. In addition, the existing electric vehicles rely on mechanical brakes, that is, through the frictional contact between the brake pads and the brake discs. The disc drives the wheel brakes, and the brake pads of this brake structure are easy to wear and have a short service life. After wea...

[0002] In order to make the electric vehicle run smoothly, reduce bumps, and increase the stability of operation, spring shock absorbers are usually arranged on the vehicle frame of the electric vehicle, or suspension and shock absorber are installed simultaneously, but the prior art suspension and shock absorber Most of them are installed separately, its structure is complicated, installation and disassembly are troublesome, maintenance is inconvenient, and the failure rate is high, and the service life is short. The disc drives the wheel brakes. The brake pads of this brake structure are easy to wear and have a short service life. After wearing out, they need to be replaced, which is troublesome to replace. Moreover, mechanical brakes are used, and the braking stability is poor.
