Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle gear transmission systems integrated with motors face challenges in achieving sufficient output torque, making it difficult to support the operation of large equipment.
Innovation Solution
A driving assembly is designed with a driving motor, transmission, power input shaft, intermediate shafts, and output shafts arranged on the transmission casing, allowing power to be transmitted through multiple intermediate shafts to reduce input power speed and increase output torque.

1Object-affected harmful factors
If a motor is integrated with a transmission system, then running noise is reduced and emission is achieved zero, but the output torque is insufficient to support large equipment operation
Solution Approach 1:
The transmission system is segmented into multiple independent shafts (input shaft, first intermediate shaft, second intermediate shaft, first output shaft, second output shaft) with distinct functions. Each shaft handles specific gear transmissions, allowing the system to achieve complex speed reduction and torque multiplication while maintaining the benefits of motor integration for noise reduction and zero emission.
Solution Approach 2:
The patent combines multiple transmission shafts and gear sets into a single integrated transmission system. The first and second intermediate shafts work together with the input and output shafts to create a unified power transmission path that multiplies torque while the motor remains integrated, preserving the noise reduction and zero emission advantages.
2Force
If multiple intermediate shafts are added to increase output torque, then the torque multiplication is achieved, but the device complexity increases
Solution Approach 1:
The first and second intermediate shafts serve multiple functions within the transmission system. They not only transmit power but also provide different gear ratio stages for torque multiplication. The first output shaft and second output shaft can simultaneously serve different drive needs, allowing the system to achieve high torque multiplication without proportionally increasing overall system complexity.
Solution Approach 2:
The transmission system employs a nested arrangement where multiple gear sets and shafts are integrated within a compact transmission housing. The first and second intermediate shafts are positioned concentrically or adjacently, with gear sets nested around them, creating a space-efficient design that reduces the apparent complexity despite the multiple moving parts.

AI summary
A driving assembly includes a driving motor with a motor shaft, a transmission, first and second intermediate shafts, a power input shaft, a first output shaft and a second output shaft. The transmission includes a casing coupled to a housing of the driving motor, the power input shaft includes a power input end coupled to the driving motor, and power is transmitted between the first output shaft and the power input shaft and between the second output shaft and the power input shaft. The first and second intermediate shafts sequentially transmit power, power is transmitted between the first intermediate shaft and the power input shaft, and the second intermediate shaft simultaneously transmits power to the first output shaft and the second output shaft.
