摘要： Disclosed is a ball screw comprising a nut (2) that is disposed on a screw (1) and is provided with a nut piece (3) and a deflection piece (4). The deflection piece (4) deflects balls from an end of a continuous raceway (5) delimited by the nut (2) and the screw (1) to a beginning of the raceway (5). The deflection piece (4) is retained on the nut piece (3) by means of a clamp (6). At least one clamp (6) leg (10) has a first resiliently tensioned section (11) and a second section (13) which is separated from the first section (11) by a slot (18). The first section (11) resiliently braces the deflection piece (4) against the nut piece (3) while the second section (13) non-removably retains the clamp (6) on the deflection piece (4).

摘要： The invention relates to a ball screw comprising a spindle nut (2) arranged on a spindel (1) and balls (3) row-arranged on a threaded path (4) in such a way that they can roll thereon. According to the invention, said threaded path (4) is bound by a threaded groove (5) formed on the spindle (1) and a threaded groove (6) formed on the spindle nut (2). The row-arranged balls are diverted towards a diverting channel (7) in order to pass from one end of the thread of the threaded path (4) to the beginning thereof. Said invention is characterised in that the distance (TES) separating the first and the last balls of the row is equal to or less than 0.3 mm, the ratio between the pitch of the threaded path (4) and the ball (3) diameter ranges from 1.02 to 1.2., the threaded grooves (5, 6) of the spindle nut (2) and the spindle (1) are embodied in the form of a gothic profile (8, 9) respectively, a pressure angle formed by the ball (3) in contact with said gothic profile (8, 9) ranges between 15 and 35 degrees.

摘要： The invention relates to a ball screw, comprising a ball roller screw (1) and screw nut (2), arranged thereon, whereby balls (3) are arranged to endlessly circulate in a ball channel (6) defined by ball tracks (4, 5) on the ball roller screw (1) and the screw nut (2). Said ball channel (6) comprises a load section (7) wound about the ball roller screw (1) the beginning and end of which are endlessly connected by means of a load-free return section (8). A minimum of two and a maximum of four balls (3) are housed in a common ball cage (10, 22), the cage traps (11) of which each house one of the balls (3), whereby the ball cage (10, 22) comprises a disc (12, 15), at the axial end thereof between adjacent balls (3), each engaging in the ball channels (4, 5) and provided on the side thereof facing the balls (3) with a concave housing (14) for the balls (3).

摘要： The invention relates to a hydraulic clutch system (1a) for a separating gear-shift clutch in motor vehicles. The inventive clutch system (1a) consists of a cylinder that is concentrically mounted around a drive shaft (5). A guide bushing (6a) is radially centered in said cylinder and is axially supported. A seal (14a) that tightens an annular gap between the cylinder (2) and the guide bushing (6a) is arranged in such a way that it is disposed inside the annular contour of a pressure chamber (16) which can be pressurized.
