Brake Actuator Positioning Element for Pedal Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of actuating devices for vehicle brake systems is complicated by the pivoting nature of the force input member, which requires precise alignment with the brake pedal, making it difficult to couple the force input member to the brake pedal after the device is installed in the vehicle.
Innovation Solution
An actuating device with an elastically deformable positioning element that holds the force input member in an installation position relative to the brake master cylinder, allowing for a predetermined orientation of the force input member's longitudinal axis and permitting deflection through elastic deformation, simplifying the installation process and enabling easy coupling to the brake pedal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the force input member is connected in an articulating fashion to follow the pivoting movement of the brake pedal, then the brake system can accommodate the pivoting movement during service braking, but the installation and coupling of the force input member to the brake pedal becomes complicated
Solution Approach 1:
The force input member is pre-positioned in a predetermined installation position by the positioning element before the actual installation process. This preliminary positioning allows the longitudinal axis of the force input member to assume a predetermined orientation relative to the brake master cylinder, simplifying the subsequent coupling to the brake pedal while maintaining the ability to accommodate pivoting movements during operation
2Manufacturing precision
If the force input member is held in a fixed installation position, then the alignment with the brake master cylinder is precise, but the ability to accommodate pivoting movements during service braking is reduced
Solution Approach 1:
The positioning element is designed to be elastically deformable, allowing it to maintain the force input member in a predetermined installation position during normal operation while permitting temporary deflection from this position to accommodate the pivoting movements of the brake pedal during service braking. The elastic deformation enables dynamic adaptation while preserving precise alignment
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
The actuating device simplifies the installation and alignment of the force input member with the brake pedal, allowing for easy mounting and ensuring proper functionality by maintaining the force input member's orientation and accommodating pivoting movements during service braking.
Implementation Method 1
The actuating device comprises at least one elastically deformable positioning element. The at least one positioning element produces a holding force with which the at least one positioning element holds the at least one force input member in an installation position relative to the brake master cylinder.
Implementation Method 2
The at least one positioning element can permit a deflection of the force input member after the holding force is exceeded. The deflection of the force input member out of the installation position can take place through elastic deformation of the positioning element.
