Problems solved by technology

[0002] In the traditional automobile power transmission system, the powertrain composed of a driving motor and a reduction device is used to drive the wheels to rotate. Due to the high speed of the driving motor, the driving motor needs to drive the wheels through a reduction device with a large reduction ratio. A reduction device with a large reduction ratio generally undergoes multi-stage reduction, which makes the reduction device larger in size and weight, resulting in a large width and weight of the entire wheel, such as common turbine structure reducers and gear reducers, which are large in size and low in transmission efficiency , and a planetary gear reduction mechanism with a high reduction ratio is installed between the motor and the wheel, although the volume of the reduction device can be effectively reduced, and the transmission accuracy is high, but the planetary gear reduction mechanism has higher requirements for material accuracy and processing methods , not suitable for assembly line modular installation

Embodiment 1

[0033] like Figure 1-7 The drive-integrated integrated wheel shown includes a motor module 1, an internal gear reduction module and a wheel module; the internal gear reduction module includes a motor mount 2 and a reduction module shell seat 11 matched with the motor mount 2; the internal gear reduction The module is detachably connected to the motor module 1 through the motor mounting seat 2; the internal gear reduction module is assembled and connected to the wheel module through the reduction module housing seat 11, which is convenient for modular assembly of the drive-integrated wheel. Among them, the motor module 1 adopts a servo motor, which improves the stability of the transmission by taking advantage of the advantages of good precision, strong anti-overload capability and stable low-speed operation of the servo motor itself, and can be applied to the occasion of quick start.

[0034] The internal gear reduction module also includes an eccentric shaft 5 fixedly connec...

Embodiment 2

[0043] like Figure 8 The schematic diagram of the structure of the four-wheel-drive trolley is shown, and four integrated integrated wheels are mounted on the frame through four suspension yokes 15, which are arranged between the two front wheels and the two rear wheels Steering electric cylinder 16 and connecting rod 17 are arranged, and the steering function of the wheel is realized by steering electric cylinder 16 and connecting rod 17 . The present invention directly connects the wheels by connecting the motor module 1 with the internal gear reduction module, and can realize the configuration of two-wheel drive, three-wheel drive, four-wheel drive or multi-drive, enriches the transmission form, and improves the transmission efficiency.

Abstract

The invention belongs to the technical field of automobile wheels, and in particular relates to an integrated drive type integrated wheel, which includes a motor module, an internal gear reduction module and a wheel module connected in sequence; the internal gear reduction module includes a motor mount and a speed reduction module matched with the motor mount The housing seat; the internal gear reduction module is detachably connected to the motor module through the motor mounting seat; the internal gear reduction module is assembled and connected to the wheel module through the reduction module housing seat. By installing the internal gear reduction module in the recessed tire, the axial installation dimension of the entire driving wheel is shortened, making the structure of the driving wheel more compact; the detachable connection between the motor module, the internal gear reduction module and the wheel module is convenient Modular production and assembly.
