Abstract

The invention provides a brake-energy recycling system for an electric vehicle. The brake-energy recycling system comprises a planetary gear mechanism, an energy storage mechanism, a double-rack frame, a gear fixing rack and an auxiliary gear, wherein a two-way overrunning clutch is arranged in the planetary gear mechanism; one end part of the double-rack frame is connected to the energy storage mechanism; the planetary gear mechanism is meshed with the auxiliary gear; a lower rack and an upper rack are arranged in the double-rack frame; the upper rack is meshed with the auxiliary gear; the lower rack is meshed with the planetary gear mechanism; the gear fixing rack is used for fixing the planetary gear mechanism and the auxiliary gear to the electric vehicle, so that the mechanical energy can be sufficiently recycled.

Description

technical field [0001] The invention relates to an energy recovery and reuse system, in particular to an electric vehicle braking energy recovery and reuse system. Background technique [0002] In terms of energy storage for electric vehicles, hydraulic energy storage is used, and hydraulic transmission relies on the pressure of liquid in a sealed container to achieve motion and power transmission. The hydraulic transmission device is essentially an energy conversion device. He first converts mechanical energy into Hydraulic energy, and then convert the hydraulic energy into mechanical energy to do work, the conversion efficiency is low. Since the leakage of the working medium and the compressibility of the liquid will affect the accuracy of the movement of the actuator, the hydraulic transmission system cannot guarantee an accurate transmission ratio and cannot be used in the internal transmission chain with strict transmission ratio requirements. The hydraulic transmission...
