Problems solved by technology

[0007] However, the inventor team discovered during the design and test process that the central drive electric drive system cannot particularly well buffer the impact of vehicle acceleration and deceleration and the impact caused by the suspension system's up and down vibrations, and it is also difficult to achieve a large reduction ratio, which cannot meet special requirements.

Embodiment Construction

[0027] The present invention will be further described below with reference to the examples and drawings.

[0028] Such as figure 1 As shown, a middle chain transmissive central electric drive system mainly includes a power input mechanism, a drive wheel 3, a deceleration input mechanism disposed on the wheel intermediate shaft 19, and is connected to the intermediate shaft 19 through the chain transmission assembly The wheel mounting shaft 2 and the reduction output mechanism provided on the wheel mount shaft 2, the wheel mount shaft 2 is disposed on the drive wheel 3, and the chain transmission assembly and the speed reduction mechanism are located on both sides of the drive wheel 3, and the power input mechanism passes. Deceleration input mechanism, chain drive assembly, wheel mounting shaft 2, deceleration output mechanism and power output member transmit power to the drive wheel 3. Among them, the chain transmission assembly and the reducer mechanism are located on both side...

Abstract

The invention discloses a middle chain transmission type central electric driving system which comprises a power input mechanism, a driving wheel, a speed reduction input mechanism arranged on an intermediate shaft outside the wheel, a wheel mounting shaft connected with the intermediate shaft outside the wheel through a chain transmission assembly and a speed reduction output mechanism arranged on the wheel mounting shaft. The power input mechanism transmits power to the driving wheel through the speed reduction input mechanism, the chain transmission assembly, the wheel installation shaft, the speed reduction output mechanism and a power output component in sequence. By the adoption of the technical scheme, the advantages of a central driving structure are reserved, the motor is arrangedin the middle of the two-wheeled vehicle, the speed reducing mechanism is arranged on one side of the driving wheel, meanwhile, a chain transmission mode is adopted, the acceleration and decelerationimpact of the two-wheeled vehicle can be buffered, and the distance change between chain wheels caused by the up-and-down oscillation of a suspension system can be reduced; in addition, the speed reduction input mechanism is additionally arranged beside the power input mechanism, and the speed reduction ratio is further increased.

Description

Technical field [0001] The present invention relates to the technical field of two-wheeled vehicle electrical drive system, and more particularly to a holistic chain-conducting central electric drive system. Background technique [0002] With the increasing harsh of environmental protection, the two-wheeled car with pure electric power is gradually replaced with traditional fuel bicycles is already a general trend. The existing two-wheeled electric vehicles generally use hub motors, homogeneous drives, and motor-side mount structures. [0003] The hub motor structure is generally driven by low speed motors and wheels, and the low speed motor has a large volume, weight weight, low efficiency (efficiency is typically 60% -80%). Further, the startup current is large, and it is easy to block the amount of heat generation. At the same time, due to poor manipulation performance, it is widely used for electric vehicles within 40km / h. It is necessary to use a higher cost of low-speed m...
