The invention relates to a brake pressure cylinder device and a brake caliper device; the brake pressure cylinder device has a common brake mechanism, a spring brake mechanism, a push rod and a projection length adjusting mechanism; the projection length adjusting mechanism has a leading part which is mounted on the push rod by moving together with the push rod and acting on the established resistance when the push rod moves for adjusting the projection length projected from the cylinder body. The projection length adjusting mechanism further has a recess arranged in the leading part, and a limiting mechanism; the limiting mechanism has a blocking part blocked with the recess arranged between a second piston and a first spring for limiting the movable area of the first piston on the movable direction.
Description
Brake pressure cylinder device and brake caliper device This application claims priority based on Japanese Patent Application No. 2007-104970 (filed on April 12, 2007). technical field The present invention relates to a brake pressure cylinder device and a brake caliper device having the brake pressure cylinder device. Adjust the protruding length of the pushrod from the cylinder body. Background technique Regarding the brake pressure cylinder device that can automatically adjust the protruding length of the push rod from the cylinder body, Patent Document 1 (Japanese Patent Publication No. 6-67725 (claim 1, FIG. 2)) discloses a brake cylinder having the following structure: A brake pressure cylinder device, the brake pressure cylinder device has in the cylinder: an output piston, a push rod connected with a brake shoe for braking the wheel tread; a friction ring assembly, which is composed of two circular plates clamped An elastic ring is used to expand it radially out...
