Abstract: The device (10), mounted elastically for example on a projecting part (30) of the caliper adjacent a projecting part (8) of the fixed support (5), incorporates a flat leaf surface (15) intended to be interposed between the cooperating slide surfaces of the caliper (31) and the support (82) and formed at the end of an intermediate leaf zone forming a flexible ramp surface (14) which cooperates, when fitting the caliper into position, with the adjacent part (8) of the fixed support (5) so as to cause the flat surface (15) to deflect and thus ensure automatic locking of the caliper, the unlocking being easily achieved manually by a similar retraction of the flat slide surface (15). The device (10) is made in a single piece from a sheet of stainless spring steel.

Abstract: A variable-damping-force shock absorber in which the motor for rotating the orifice adjuster is housed within the cylinder and the orifice-adjuster position sensor for outputting binary coded sensor signals is incorporated. Therefore, it is possible to reduce noise generated from the motor while improving the lifetime of the motor because mud or rain water will not adhere onto the motor and to improve the precision and the response speed in rotating the orifice adjuster because the adjuster can be feedback controlled in digital fashion. Further, since the driven shaft of the motor or the reduction gear is loosely coupled with the orifice adjuster in the axial direction thereof, it is possible to reduce the torque or the size of the motor, because fluid pressure is not directly applied to the driven shaft via the orifice adjuster.

Abstract: A rail vehicle disc brake arrangement includes a yoke (1) with a brake cylinder (11) and a slack adjuster (16). In order to obtain advantages as regards design, function and space requirements the yoke (1) comprises two telescoping yoke parts: a fixed part (4) and a movable part (5). The slack adjuster (16) is arranged to act between these two parts. The brake cylinder (11) on the movable yoke part is connected to a yoke lever (6), which is pivotally attached to the movable part, has a pad holder (8) with a brake pad (9), and controls the slack adjuster (16).
