Electrically-controlled hydraulic or pneumatic kinetic energy recovering and releasing device

Abstract

The invention discloses an electrically-controlled hydraulic or pneumatic kinetic energy recovering and releasing device. The electrically-controlled hydraulic or pneumatic kinetic energy recovering and releasing device comprises a hydraulic accumulator, a pressure limiting valve, a radiator, a reversing valve, a hydraulic pump/motor, a clutch speed change mechanism, a transmission or driving axle, a hydraulic oil tank, an electric control unit and a sensor, wherein one end of the clutch speed change mechanism is connected with the transmission or driving axle, and the other end of the clutch speed change mechanism is connected with a power shaft of the hydraulic pump/motor; the hydraulic accumulator, the pressure limiting valve, the radiator, the reversing valve, the hydraulic oil tank and the hydraulic pump/motor are connected through a pipeline; the electric control unit is connected with the sensor, a controller portion on the hydraulic pump/motor and a controller portion on the reversing valve through leads. The kinetic energy of a moving object is transformed into molecular potential energy for storage by using a hydraulic accumulating or pneumatic accumulating method, and the stored molecular potential energy is transformed into the kinetic energy of the moving object when the object moves once again or accelerates, thereby fulfilling the aims of recycling, lowering the energy consumption and increasing the energy utilization ratio.

Description

technical field [0001] The invention relates to the field of energy recovery and utilization, in particular to an electronically controlled hydraulic or pneumatic kinetic energy recovery and release device. Background technique [0002] Now some vehicles, motors and some complex moving machinery are mostly braked by mechanical friction braking, that is, their kinetic energy is converted into heat energy through friction between objects and then disappears, so that kinetic energy is wasted during braking. Moreover, the large amount of heat energy easily transformed into by long-term friction will also increase the temperature of the brake, which will affect the braking effect of the brake, and even make it more likely to lose the braking ability, thereby causing mechanical failure and personal safety. Problem; there are still some motor brakes that use the method of supplying DC power to the motor to slow down or stop it. This will not only increase the DC equipment, but also...

Problems solved by technology

[0002] Now some vehicles, motors and some complex moving machinery are mostly braked by mechanical friction braking, that is, their kinetic energy is converted into heat energy through friction between objects and then disappears, so that kinetic energy is wasted during braking. Moreover, the large amount of heat energy easily transformed into by long-term friction will also increase the temperature of the brake, which will affect the braking effect of the brake, and even make it more likely to lose the braking ability, thereby causing mechanical failure and personal safety. Problem; there are still some motor brakes that use the method of supplying DC power to the motor to slow down or stop it. This will not only increase the DC equipment, but also waste some electric energy; moreover, most of the existing friction plates contain metal in the composition Elements, such as copper and iron, cannot be recycled and reused after being worn out, and the worn-out substances also pollute the environment. The high temperature caused by braking can easily cause vehicle tires to blow out, thus causing traffic accidents
