Interchangeable Shift Actuators for Modular Transmission Housings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing shifting systems lack flexibility and efficiency in manufacturing due to the need for early selection of either electrically or pneumatically actuated shift devices, which affects transmission design, installation space, and component arrangement, leading to increased complexity and costs.
Innovation Solution
A modular shifting system that allows interchangeable electrically and pneumatically actuated shift devices, reducing the number of required components and enabling later selection based on customer and market requirements, with both types having similar housing dimensions to maintain consistent installation space and component arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an electrically actuated shift device or a pneumatically actuated shift device is selected early in the manufacturing process, then the transmission design and installation space can be determined, but the manufacturing flexibility is reduced and the number of different components increases
Solution Approach 1:
The transmission housing is designed with a universal mounting structure that can accommodate both electrically actuated and pneumatically actuated shift devices. The housing includes a mounting plate with standardized mounting holes and interfaces that are compatible with both types of shift devices, allowing the same transmission housing to serve multiple functions and support different actuation methods without requiring separate designs.
2Adaptability or versatility
If different types of shift devices are designed with different dimensions, then each shift device can be optimized for its actuation method, but the installation space requirements vary and surrounding component arrangement becomes more complex
Solution Approach 1:
The invention maintains consistent external dimensions and mounting interface parameters for both electrically and pneumatically actuated shift devices. The housing dimensions, mounting plate size, and hole patterns are standardized to be identical for both device types, allowing interchangeable installation without modifying the transmission housing or surrounding component arrangement, thus decoupling device selection from spatial constraints.

AI summary
A modular shifting system is provided. The modular shifting system comprises a transmission including an input shaft and an output shaft, a transmission housing, gear trains accommodated in the transmission housing and constituting at least two shiftable gear ratios for establishing a transmission ratio between the output shaft and the input shaft, and a shift device for shifting between the at least two gear ratios. The shift device is detachably attached to the transmission housing. The shift device is one of an electrically actuated shift device and a pneumatically actuated shift device, and the modular shifting system is configured such that the electrically actuated shift device is interchangeable with the pneumatically actuated shift device and vice versa.
