Parking Lock Mounting on Intermediate Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing parking lock arrangement in vehicle transmissions requires significant installation space due to its integration with the hydraulic control unit, leading to increased structural design complexity and limited space availability.
Innovation Solution
The parking lock is reconfigured to be mounted on an intermediate plate within the vehicle transmission housing, separate from the hydraulic control unit, with the locking mechanism and actuating unit integrated into the plate, allowing for axial parallel alignment of key components to minimize space usage and maintain functional integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the parking lock is integrated into the hydraulic control unit, then the functional integration is improved, but the installation space is increased
Solution Approach 1:
The parking lock is separated from the hydraulic control unit and mounted on the intermediate plate instead. This segmentation allows the parking lock to be positioned independently, reducing the installation space requirement in the hydraulic control unit while maintaining functional integration through the common transmission housing structure.
2Reliability
If the parking lock cylinder is positioned in the hydraulic control unit, then the actuating function is ensured, but the structural design complexity is increased
Solution Approach 1:
The intermediate plate serves as an intermediary mounting surface for the parking lock cylinder. This intermediary structure simplifies the overall design by providing a dedicated mounting location that is accessible and does not interfere with the hydraulic control unit's internal structure, thereby reducing structural design complexity while ensuring the actuating function remains intact.
3Area of stationary object
If the parking lock is mounted on the intermediate plate, then the installation space is reduced, but the connection specifications must be modified
Solution Approach 1:
The intermediate plate is designed with multi-functionality, serving both as a structural support element and as a mounting surface for the parking lock cylinder. By integrating the parking lock mounting function into the existing intermediate plate design, no additional connection specifications or seal modifications are required, as the plate already incorporates necessary mounting features and sealing arrangements.
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 significantly reduces installation space requirements, maintains functional efficiency, and allows for cost-effective integration without modifying existing seal specifications, providing tolerance advantages and a more compact design.
Implementation Method 1
The actuating unit is designed as a hydraulic cylinder arrangement which is coupled to a mechanical switch connected between the hydraulic cylinder arrangement and the locking mechanism

AI summary
A parking lock in a vehicle transmission includes a locking mechanism for locking and releasing a parking interlock gear (1) and an actuating unit. The actuating unit is coupled via a coupling mechanism to the locking mechanism in order to actuate the locking mechanism between an interlock position and a release position of the parking interlock gear (1). The parking lock is arranged on an intermediate plate (2) in a housing of the vehicle transmission.
