Kinetic energy storage apparatus

Abstract

The invention discloses a machine mainly used for storing and releasing kinetic energy when a bus is braked and started. The machine includes a flywheel (2) and a power input/output shaft (6); the flywheel (2) is in transmission linkage with the power input/output shaft (6) through a friction clutch (8); an overrunning clutch (10) and an electric motor (1) are arranged beside the flywheel (2); and the flywheel (2) is in transmission linkage with the electric motor (1) through the overrunning clutch (10). When the machine is used by a vehicle, such as the bus, etc., the driving kinetic energy of the vehicle can drive the flywheel (2) to turn faster through braking; after braking, the electric motor (1) further accelerates the flywheel (2) to a high speed by the overrunning clutch (10) when the friction clutch (8) is separated for stopping the vehicle; and the stored kinetic energy and electric energy can be passed from the flywheel (2) to the vehicle for starting the vehicle. Compared with other similar machines, the machine has the advantages that the vehicle can use cheap and renewable electrical energy when the vehicle is started; the effects of saving oil and reducing pollutant are obvious; and the machine is simple, reliable, and low in cost. Therefore, the machine is easy to popularize and apply.

Description

technical field [0001] The invention relates to a power mechanical device, especially an energy-saving mechanical device used for kinetic energy storage and storage during braking and starting of motor vehicles such as buses. Background technique [0002] For a long time, how to recover the kinetic energy of power equipment (especially motor vehicles such as buses) efficiently and at low cost has been a major energy-saving problem in the machinery industry. Two kinds of so-called " hybrid electric buses " have occurred in recent years, and a kind of has installed braking storage energy hydraulic system additionally, and another kind is to have installed braking storage energy electric system additionally. When braking to decelerate or going downhill, the driving kinetic energy or potential energy of the two vehicles is converted into hydraulic energy or electric energy and stored in the hydraulic accumulator or battery; when the vehicle starts or accelerates, the energy stor...

Problems solved by technology

Compared with the above two kinds of hybrid electric buses, the "braking energy storage flywheel device" installed on the bus has the same or better energy-saving and pollution-reducing effects, can subsidize braking and lower cost, and basically does not need to change gears when starting. However, there are still major shortcomings such as heavy weight increase, low manufacturing and installation costs, and difficulty in popularization and application, which need to be improved.
