Brake Hydraulic Unit Adapter With Self-Centering Interface Plate

The adapter is designed with a universal interface plate that can accommodate different types of pedal travel transducers through standardized mounting holes and positioning features. The interface plate serves multiple functions: providing mounting surfaces for various transducer types, ensuring precise alignment through the self-centering mechanism, and maintaining sealing integrity. This universal design allows the same adapter to work with different transducer geometries while preserving alignment precision.

The interface plate acts as an intermediary component between the adapter and the pedal travel transducer. It provides a standardized interface that mediates the connection between the fixed adapter geometry and the variable transducer geometries. The interface plate includes positioning holes and mounting features that facilitate precise alignment while accommodating different transducer types, thus resolving the contradiction between versatility and precision.

The adapter incorporates a self-centering mechanism that automatically aligns the interface plate with the adapter body during assembly. The self-centering features include positioning holes and corresponding protrusions that guide the interface plate into the correct position without requiring external alignment tools or complex adjustment procedures. This self-service approach enhances mounting reliability while avoiding the need for additional complex alignment devices.

The adapter is pre-equipped with integrated centering features and positioning elements during manufacturing. The self-centering mechanism is built into the adapter structure beforehand, including precisely positioned holes and protrusions that prepare the assembly for accurate alignment. This preliminary action ensures that when the interface plate is installed, the alignment is automatically achieved, enhancing reliability without adding operational complexity.

The alignment and sealing functions are segmented into distinct features on the interface plate and adapter. The self-centering mechanism is separated into positioning holes and corresponding protrusions, while the sealing function is provided by a dedicated sealing bead or groove. This segmentation allows each feature to be optimized independently: the positioning features ensure precise alignment, while the sealing features provide reliable sealing. The segmented design simplifies manufacturing by allowing standardization of these features across different adapter types.

The self-centering mechanism utilizes parameter changes in the form of geometric features with specific tolerances. The positioning holes and protrusions are designed with controlled dimensional parameters that enable automatic alignment within acceptable tolerances. By carefully selecting and controlling these geometric parameters, the system achieves precise alignment without requiring excessively tight manufacturing tolerances across the entire adapter, thus balancing alignment precision with manufacturing ease.
