Abstract

The invention discloses an electric automobile brake energy regeneration transmission device with an elastic rubber belt energy accumulator and aims at providing an electric automobile brake energy regeneration transmission device which is high in energy conversion efficiency, large in energy density, light in weight and simple in structure. The electric automobile brake energy regeneration transmission device comprises the elastic rubber belt energy accumulator and a gear transmission case. The power connecting end of the elastic rubber belt energy accumulator is connected with the power connecting end of the gear transmission case, and two ends of a first shaft of the gear transmission case are respectively connected to the output end of a speed changer and the power input end of a main speed reducer. The electric automobile brake energy regeneration transmission device is used for converting kinetic energy in the electric automobile braking process into elastic potential energy to be stored in the elastic rubber belt energy accumulator, converts the elastic potential energy stored in the elastic rubber belt energy accumulator into electric automobile kinetic energy in the electric automobile starting process, achieves braking energy regeneration of an electric automobile and achieves the purposes of reducing electric quantity consumption of the electric automobile and increasing a driving range of the electric automobile.

Description

Technical field [0001] The present invention involves a kind of electric vehicle braking energy regeneration transmission device. More specifically, the invention involves a elastic rubber belt energy storage energy -type electric vehicle braking energy regeneration transmission device. Background technique [0002] At present, the research on the recycling of electric vehicle braking energy is mainly to convert kinetic energy into electrical energy and charge the battery.The energy storage method has low power density, small charging and discharge frequency, and cannot quickly transform the large amount of energy absorbed by the absorbed energy.When the vehicle is braking or starting, it needs to be quickly obtained or released, which has greatly limited the application of energy storage batteries.In addition, in the process of charging the battery, if you can adjust the braking energy, it will help improve the effect of charging and improve the service life of the battery.Howev...
