Embodiment 1

[0034] As attached figure 1 , Attached figure 2 , Attached image 3 And Figure 4 As shown, the hybrid drive system based on hydraulic spring energy storage drive of the present invention includes an electric motor 25, a battery 24, a controller 22, a drive shaft 21 and a hydraulic spring energy storage device 23. The battery 24 is connected to the electric motor 25, and the electric motor 25 drives The drive shaft 21 rotates, and the rotating drive shaft 21 acts on the hydraulic spring energy storage device 23 and transmits the braking energy to the hydraulic spring energy storage device 23. The hydraulic spring energy storage device 23 is used to recover the braking energy and restrain the energy through deformation. The kinetic energy is converted into elastic energy for storage. When the vehicle body is accelerating or running at a high speed, the hydraulic spring energy storage device 23 can transform the elastic energy into kinetic energy through deformation and transmit ...

Embodiment 2

[0051] The electric motor hybrid driving method based on the hydraulic spring energy storage device of the present invention starts and drives the vehicle body through the electric motor hybrid drive system based on the hydraulic spring energy storage device disclosed in Embodiment 1. The hydraulic spring energy storage device 23 includes three types of work The states are the unchanged state, the energy storage state that can recover the braking energy, and the energy release state that can release the energy. The braking energy is recovered through the energy storage state of the hydraulic spring energy storage device 23, and the hydraulic spring energy storage device 23. The energy released in the discharged state assists the electric motor 25 to drive the vehicle body. Specifically, it includes the following working modes:

[0052] Mode 1: During the driving process of the electric motor 25, when the vehicle body accelerates, the stored energy value of the hydraulic spring en...

Abstract

The invention discloses a motor hybrid driving system based on hydraulic spring energy storing device and driving method and belongs to the field of motor hybrid power driving system, and a technical problem to be resolved is how to recycle and release the energy generated during the process of a car braking or a car starting through a simple and easy-to- implement energy storing and releasing device. The system comprises an electromotor, a storage battery, a controller, a drive shaft, and further comprises a hydraulic spring energy storing device which includes a hydraulic pump, a hydraulic cylinder, a fixing plate, a connecting plate, an energy storing spring and a stop device, wherein the hydraulic pump, an oil tube and the hydraulic cylinder are sequentially communicated and from a power transmission mechanism, a displacement sensor is arranged in the cylinder barrel of the hydraulic cylinder, and the displacement sensor, the hydraulic pump and the electromotor are all connected with the controller. The driving method comprises that braking energy is recycled by the energy storing status of the hydraulic spring energy storing device, and the energy released by the energy releasing status of the hydraulic spring energy storing device assists the electromotor to drive a vehicle to run.

Description

Technical field [0001] The invention relates to the field of automobile hybrid drive systems, in particular to a motor hybrid drive system and a drive method based on a hydraulic spring energy storage device. Background technique [0002] The power during the starting and running of the vehicle is provided by the electric motor of the vehicle, which consumes a lot of fuel during the braking and starting of the vehicle. The kinetic energy is lost in the form of heat when the vehicle is braking, resulting in a waste of energy. [0003] A Chinese patent published on July 29, 2015, with the publication number CN 104802774 A, proposed a scroll spring-based automobile braking energy reuse device, including a transmission unit and a moving unit, wherein the transmission unit includes a brake bevel gear , Accelerating bevel gears and matching bevel gears. Brake bevel gears and accelerating bevel gears are coaxially mirrored and symmetrically mounted on the drive shaft of the car wheels. Th...
