Clockwork spring braking energy recovery device

Abstract

The present invention relates to a spring energy-collecting device which can be used for storing, releasing and using the energy of vehicle brake, and belongs to the technological field of carrying tools. In the technical proposal, a vehicle shaft is dynamically provided with a fitting external shaft lining pipe, and is fixedly provided with a torque input rubber wheel and a torque output rubber wheel; the external shaft lining pipe is connected with the spring shell through a swinging shrapnel; the spring shaft is respectively provided with an upper spring rubber wheel which exactly faces the torque output rubber wheel, an output gear which is connected with a spring output rubber wheel in the way of transmission, a one-way ratchet; the spring output rubber wheel exactly faces the torque input rubber wheel; the external shaft lining pipe is provided with an electromagnet, which is arranged close to the torque output rubber wheel and provided with an open-close contact arranged in the position of the brake; an electromagnet is arranged close to the torque input rubber wheel and provided with open-close contact arranged in the position of the accelerator. The spring energy-collecting device has the advantages of simple structure, small loss of energy and light weight, and is suitable for light electric vehicles.

Description

technical field

[0001] The invention relates to an energy recovery device for storing and releasing the energy of vehicle braking, in particular to a spring brake energy recovery device, which belongs to the technical field of vehicles. Background technique

[0002] At present, there are two main types of braking energy recovery methods: one is to drive a generator to generate electricity from the braking energy and store the electric energy; the other is to convert the braking energy into compressed air energy for storage. These two types have energy loss in the process of energy conversion, and the structure is more complicated and the cost is higher. The best energy recovery method is mechanical energy storage, but it is unrealistic to use it on current fuel vehicles, because the structure of mechanical energy storage is huge and the energy recovery device is too heavy. Therefore, for light-duty electric vehicles, it is necessary to find an energy recovery device with hi...
