Embodiment Construction

[0049]The specific implementation manner of the present invention will be described in further detail below by describing the best embodiment with reference to the accompanying drawings.

[0050] Such as figure 1 , Figure 17 and Figure 18 As shown, the electric wheel side drive system includes a deceleration drive system located in the wheel hub 1 and a direct drive system that directly drives the wheels with the wheel hub 1; the deceleration drive system and the direct drive system can be designed in different working conditions To ensure that the motors of each system work near the rated power, so as to ensure the output efficiency of the motors; the deceleration drive system and the direct drive system can also work under certain heavy load conditions (such as acceleration, climbing, and load) at the same time. In order to ensure that the electric vehicle has a strong driving force and acceleration performance; it can not only meet the normal power requirements and redu...

Abstract

The invention discloses an electric vehicle wheel side driving system and a driving method. The electric vehicle wheel side driving system comprises a deceleration driving system disposed in a wheel hub and a direct driving system fixedly connected with the wheel hub and directly driving a wheel. The electric vehicle wheel side driving method is realized via the electric vehicle wheel side driving system. By the use of the electric vehicle wheel side driving system and the driving method, motors of various systems can be guaranteed to work within the rated power and motor output efficiency can be ensured; demands for normal power can be met and overall vehicle weight can be reduced; large transmission ratio is achieved and high mechanical transmission efficiency is provided; and the electric vehicle wheel side driving system possesses compact structure, facilitates spatial arrangements and meets requirements for light weight of the electric vehicle.

Description

technical field [0001] The invention relates to the field of design and manufacture of electric vehicles, in particular to an electric wheel-side driving system and a driving method thereof. Background technique [0002] Wheel hub electric vehicle is an emerging form of electric vehicle drive. It directly installs the motor in the wheel hub, omitting the traditional clutch, transmission, final reducer and differential, which greatly simplifies the structure of the vehicle, improves the transmission efficiency, and can realize the control of the electric wheel through control technology. Electronic differential control. Therefore, electric wheels become the development direction of electric vehicles in the future. [0003] The electric wheel electric drive system has two basic forms: direct drive electric wheel and wheel side reducer electric wheel. The electric wheel and the wheel of the direct-drive electric vehicle form a complete component assembly, and the electronic ...
