An electric vehicle brake energy storage device

Abstract

The invention discloses a brake energy storage device of an electric vehicle. The brake energy storage device comprises a hollow shaft, a left gear disk, a rack and a right gear disk which are arranged on the hollow shaft in a sleeving manner in sequence, and an outer brake disk arranged outside the left gear disk, the rack and the right gear disk in a sleeving manner, wherein a left pull rod and a right pull rod are arranged in the hollow shaft; the left pull rod is connected with a left brake handle of the electric vehicle through a steel wire; the right pull rod is connected with a right brake handle of the electric vehicle through a steel wire; the end socket on the outer ring of the rack is fixed on the left gear disk; the end socket of the inner ring of the rack is fixed on the right gear disk; the left gear disk and the right gear disk in initial states are meshed with the hollow shaft; the left gear disk is connected with the left pull rod, and the right gear disk is connected with the right pull rod; left teeth and right teeth are arranged on the inner rings of the two ends of the outer brake disk, respectively. The brake energy storage device of the electric vehicle is simple in structure, and the cost of parts is low; batch production is facilitated, and energy storage and release are stable and reliable; furthermore, the brake energy storage device is easy to operate and feasible, and is in particular applicable to brake energy storage and starting energy release of the electric vehicle.

Description

technical field

[0001] The invention relates to an energy storage device, in particular to an electric vehicle brake energy storage device, which belongs to the technical field of mechanical energy storage. Background technique

[0002] With the rapid development of modern motor technology, battery technology and control technology, electric vehicles have gradually become another means of transportation for us. Electric vehicles use electric energy as energy storage, and the electric energy in the battery is converted into power mechanical energy to drive the vehicle during driving.

[0003] According to the physics of motion, a moving vehicle has kinetic energy, and the greater the overall weight and the faster the vehicle, the more kinetic energy it has. At present, most of the brake systems of electric vehicles use the principle of frictional braking, so that all the kinetic energy of the electric vehicle is converted into heat loss and released. This part of energy is c...
