Problems solved by technology

There are also some energy recovery methods for electric vehicles on the market now, but most of them realize the energy recovery process during the braking process through the dragging of the motor. Due to the existence of the motor load, this method is easy to cause a drag feeling during the braking deceleration process. The comfort of the process is not good, there is no flexible cushioning effect

Abstract

The invention relates to the technical field of new energy automobile energy recovery, in particular to an electric automobile intelligent speed reduction energy recovery system which comprises a motion input connecting device, a speed change system and a damping power generation system. The outer end of the motion input connecting device is connected with an input mother gear. The speed change system comprises a conical cylinder transmission device, a speed change control mechanism, a contact wheel mechanism, a control pull rod, a box body and a transmission output mechanism, a left side cavity, a right front cavity and a right rear cavity are formed in the box body, and the conical cylinder transmission device comprises a first conical cylinder and a second conical cylinder. According to the invention, a periodic linear motion control process is realized through a double-cone cylinder type transmission connection structure and a pure mechanical slot shifting mechanism, so that a control process of variable-speed motion is realized.

Description

technical field [0001] The invention relates to the technical field of energy recovery of new energy vehicles, in particular to an electric vehicle intelligent deceleration energy recovery system. Background technique [0002] With the development of electric vehicle technology, the requirements for the driving quality of electric vehicles are also getting higher and higher. In many research aspects of electric vehicle technology, braking technology is an important factor affecting the driving quality of the vehicle, and due to the overall electrification demand of the vehicle, if the energy loss during the braking process can be converted into reserve energy for the overall electrification of the vehicle The use demand will have an important impact on the energy utilization of vehicles. There are also some energy recovery methods for electric vehicles on the market now, but most of them realize the energy recovery process during the braking process through the dragging of ...
