AI Technical Summary
The caliper body for a vehicular disc brake experiences uneven stress distribution during braking, leading to partial deformation and unsatisfactory braking feel due to the difference in stiffness between the intermediate bridge part and the disc radial center section, which is exacerbated by the cylindrical shape of the working fluid communication hole.
The working fluid communication hole is offset closer to the disc radial outer side than the center axis of the cylinder holes, and the intermediate bridge part is formed on the disc radial outer side, with thinning parts and vehicle body attachment parts strategically placed to adjust stiffness and reduce deformation, while maintaining the appearance and improving air ventilation.
This configuration suppresses the stiffness of the intermediate bridge part, balances stress distribution, reduces deformation, and enhances braking feel without altering the caliper body's appearance, while also reducing weight and size.
