Problems solved by technology

[0002] One end of the two friction plates of the existing electric bicycle braking device is fixed on the outer casing, and cannot move forward, backward, left, and right, which is prone to partial braking and ineffective braking. The braking distance cannot be guaranteed, and the braking centering circle formed by the two friction plates cannot be guaranteed. When braking, the contact area between the two friction plates and the brake hub is small, the local wear of the friction plates is serious, and the service life is short

Abstract

The invention discloses a hub type brake of an electric bicycle, which has long service life. The brake comprises a shell and left and right friction plates movably arranged on the shell, wherein a rear fixed seat is arranged at the rear end of the shell; a rear return spring and a front return spring are arranged between the left and right friction plates; a front fixed seat is arranged at the front end of the shell; an adjusting spline nut is movably arranged in the front fixed seat; spline gears are arranged on the adjusting spline nut; an adjusting screw is arranged in the adjusting spline nut; the right end of the adjusting spline nut pushes against the left end of a sliding adjusting push rod; the sliding adjusting push rod is movably arranged in a square shaft; a gear striking device is arranged at the upper end of the square shaft; a limiting groove matched with the square shaft is arranged in the shell; the lower end of the square shaft is connected with a swing arm; and the swing arm is connected with the shell by a torsion spring.

Description

technical field [0001] The invention relates to an electric vehicle braking device, in particular to an electric bicycle hub type brake. Background technique [0002] One end of the two friction plates of the existing electric bicycle braking device is fixed on the outer casing, and cannot move forward, backward, left, and right, which is prone to partial braking and ineffective braking. The braking distance cannot be guaranteed, and the braking centering circle formed by the two friction plates cannot be guaranteed. When braking, the contact area between the two friction plates and the brake hub is small, the local wear of the friction plates is serious, and the service life is short. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hub type brake of an electric bicycle with long service life. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present inven...
