Abstract

The invention discloses a mechanical energy storage type automobile brake energy recovering and releasing device. Two-level gear transmission is adopted to be matched with a metal belt type stepless speed change device, when an automobile is braked, kinetic energy is transmitted to an energy storing flywheel through a transmission shaft of the automobile, and speed increase of the energy storing flywheel is used for storing energy to recover the brake energy; when the automobile is restarted or accelerated, the energy storing flywheel decelerates, stored energy is supplemented to the transmission shaft of the automobile again to release the energy, and connection or disconnection between the energy storing flywheel and the transmission shaft of the automobile can be controlled through combination and disconnection between an electromagnetic clutch and a transmission shaft clutch, so that the energy recovering and releasing device is started up or shut down. Energy transfer between the transmission shaft of the automobile and the energy storing flywheel, and the energy magnitude and work rotating speed range of the energy storing flywheel can be adjusted.

Description

technical field [0001] The invention relates to a mechanical energy storage type vehicle braking energy recovery and release device, which is mainly used for temporary storage of kinetic energy during vehicle braking and energy supplementation during vehicle starting or acceleration. Background technique [0002] When the car brakes, through the friction of the brake disc and the friction plate, the kinetic energy of the car is converted into heat energy, which directly causes energy loss. Therefore, it is of great practical significance to recover the energy when the car brakes, and then release it to the power system of the car. The existing braking energy recovery method mainly converts the mechanical energy of the car into electrical energy through the motor, and stores it in the battery in the form of electrical energy. There are problems of energy conversion and low efficiency, and the battery has problems of discharge depth, service life and environmental pollution. ...
