Abstract

The invention provides a brake cylinder device and a disc brake device. The brake cylinder device has a gap adjustment mechanism, which can be realized at low cost without being affected by surrounding environments such as temperature and humidity, and can also reduce the size of the radial dimension of the cylinder main body. A threaded shaft (24) connected to the brake output portion (21) is accommodated inside a guide pipe (25) attached to the piston (22). The thrust spring (26) applies force to the threaded shaft (24) in the braking direction. A clutch nut (27) is screwed to the front end side of the threaded shaft (24), and a front clutch (28) capable of contacting the clutch nut (27) is arranged at a position closer to the front side than the clutch nut (27). A rear clutch (29) capable of coming into contact with the clutch nut (27) is disposed on the rear side of the clutch nut (27). The stopper (30) is arranged to be movable in the axial direction of the threaded shaft (24) relative to the clutch nut (27) and the guide tube (25), and the movable range relative to the cylinder main body (20) is limited . The adjustment spring (31) is provided such that one end thereof abuts against the stopper (30) and can bias the clutch nut (27) in a reverse braking direction.

Description

technical field [0001] The present invention relates to a brake cylinder device having a clearance adjusting mechanism for automatically adjusting the pressure of a brake output part in a state in which the brake is released, and a disc brake device having the same. The gap between the end and the braking action position. Background technique [0002] A brake cylinder device disclosed in Patent Document 1 is known, which has a gap adjustment mechanism for automatically adjusting from the end of the brake output part in the state where the brake is released to the brake action position ( position where braking force can be generated). In the brake cylinder device disclosed in Patent Document 1, a jack and a guide member capable of moving together with the jack are provided, and the jack has a concave-convex surface formed on its outer surface. Moreover, an O-ring engaged with the uneven surface is arranged in the space between the guide member and the ejector rod. When a fo...
