Solution Overview
Problem
Conventional electric drive motors for track-type tractors require separate gear systems, decreasing efficiency and increasing installation time due to their connection with planetary gear sets, and are not configured for rear entry into frame housings.
Innovation Solution
A rear entry electric drive motor module with an integrated electric drive planetary gear assembly and motor, allowing for direct insertion into a high drive track-type tractor's frame housing, reducing the need for additional gear systems and simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If separate gear systems are used with conventional electric drive motors, then the motors can be connected to planetary gear sets, but this decreases the efficiency of the electric drive motor and increases device complexity
Solution Approach 1:
The patent combines the electric motor and planetary gear assembly into a single integrated unit. The motor housing directly incorporates the planetary gear set, eliminating the need for separate gear systems and external connections. This merging reduces energy losses from additional gear interfaces while simplifying the overall device structure.
2Ease of manufacture
If conventional electric drive motors are connected to planetary gear sets during installation, then the motors can be installed, but this requires additional installation time and steps
Solution Approach 1:
The planetary gear assembly is pre-integrated into the motor housing during manufacturing, creating a ready-to-install module. This preliminary action eliminates the need for separate gear set installation steps, allowing the entire drive unit to be installed as a single component and significantly reducing installation time.
Solution Approach 2:
The patent creates a modular integrated drive unit that can be installed as a single segment. By segmenting the complex assembly into a pre-assembled motor-gear module, the installation process is simplified from multiple discrete steps to a single installation action.
3Power
If conventional electric drive motors are used, then they can provide driving power, but they are not configured for rear entry into frame housings adding to assembly time
Solution Approach 1:
The patent inverts the conventional installation approach by designing the integrated motor-gear unit to enter the frame housing from the rear rather than from the front. This inverted entry configuration allows for more efficient assembly and reduces installation time while maintaining full driving power capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances the efficiency of the electric drive system by eliminating gear losses and reduces assembly time, while enabling direct torque transfer to the tracks, thus improving fuel efficiency and reducing emissions.
Implementation Method 1
Electric drive motors generally supplement or provide driving power to help reduce emissions and increase fuel efficiency. In operation, electric drive motors typically generate an output torque
Implementation Method 2
The rear entry electric drive motor module includes an electric drive planetary gear assembly... direct torque transfer to the tracks
