A switchable clamp-type locking mechanism with an output shaft (3) that rotates in relation to a housing (1) is provided. Furthermore, clamping elements, in particular clamping balls or clamping rollers (4) are provided that are pushed by a spring force into a clamping gap (16) in their clamped position and are confined by a smooth track (15) on the housing (1) and by locking ramps (13, 14) on the output shaft (3). A drive shaft (2) to rotate the output shaft (3) is provided. The clamping elements are moved into a release position using a device by means of which the clamping elements are freed to rotate the output shaft (3). A slide (7) that is fixed to the output shaft (3) is form-locked to the housing (1) in the clamped position of the clamping elements and is disengaged from the housing (1) in the release position of the clamping elements.

A shiftable clamping-type locking mechanism, includes two track-defining elements and a plurality of clamping members, e.g. rollers or balls, arranged between the tracks of the elements and so spring-biased as to seek a clamped position. The clamping members are shiftable by a control unit from the clamped position into a release position in which the clamping members are liberated from the tracks so that the two elements can be freely moved relative to one another. A coupling unit positively connects the two elements to one another in order to prevent an undesired slip between the elements.

A clamp-type locking mechanism includes a housing (1) with an inner cylindrical clamping surface (3) and with driving elements (5) and driven elements (4) positioned concentrically therewith. The driven element (4) is provided with clamping ramps (23, 24) facing the clamping surface (3), which have arranged thereon clamping roller pairs formed of two clamping rollers (25) successively placed along the circumference. Both clamping rollers (25) are spring-biased by an interposed spring element (26, 30) in direction away from each other towards the clamping surface (3) and the clamping ramp (23, 24), with the driven element (4) being provided with stops (28) for claws (19) of the driving element (5). The claws (19) have on the sides facing the stops (28) contact areas (27) for one of each of the clamping rollers (25) of a clamping roller pair, wherein a circumferential clearance between the stops (28) and the claws (19) is greater than a circumferential clearance between the contact areas (27) and the clamping rollers (25). It is proposed to construct the driven element (4) in form of a thin-walled sheet metal part (6) with clamping ramps (23, 24) and stops (28) formed thereon in a non-cutting manner. It is furthermore proposed to construct the driving element (5) in form of a plastic disk (8) with integral plastic claws (19), and of a driving member (9) so connected to the plastic disk (8) that a rotation therebetween is prevented.
摘要:
The invention relates to a method for monitoring an on-load tap changer that is used to switch between winding taps of a tapped transformer without interrupting the load current and is actuated using a motor drive. According to the invention, prior to the actual load switching process, the on-load tap changer is initially moved a short distance, preferably against the direction in which the load is subsequently switched. In said initial process, it is verified whether the on-load tap changer has moved, i.e. has left its previous stationary position, and/or whether the torque on the motor drive has exceeded a predefined threshold value. The actual load switching process takes place only once the test has yielded a positive result.
摘要:
The seat adjustment mechanism has a housing with an outer ring and an inner ring. The rings are arranged concentrically. Clamping bodies interact with double clamping ramps on the rings and are arranged in an annular space between the rings. Spring supports pivot in relation to each other, interact with a stop on the housing, are arranged concentrically with the rings, and engage in each case both in the annular space and in an inner space arranged radially within the inner ring. The spring supports are braced in relation to each other by a spring, which is arranged in the inner space to secure the clamping bodies in the center of the double clamping ramps. Stop surfaces of the spring supports are acted upon by a force in the direction in which they are minimally spaced apart.

The invention relates to a roll stabilizer for the chassis of a motor vehicle, comprising an actuator (3), which is mounted between anti-roll bar halves (1, 2) and which rotates these about a rotation axis in opposite directions as necessary. The curved path carriers (4, 5) of the actuator that are assigned to the roll stabilizer halves (1, 2) are each provided with a curved path (17, 18) inside of which a coupling element (13) is guided that can be displaced along these curved paths (17, 18) via an actuating drive (7, 10). The U-shaped or V-shaped curved path (18) of one curved path carrier (5) has two curved path branches (19, 20) that are arranged in a mirror symmetric manner in relation to a longitudinal central plane containing the rotation axis of the actuator (3).
摘要:
The application describes a clamping device for a steering column, in which a first clamping plate element is rotatable between a released position and a clamped position in relation to a second clamping plate element, wherein a rolling body which establishes contact is provided between the clamping plate elements. The second clamping plate element comprises a clamping ramp with a contour for the rolling body so that when the clamping plate elements are rotated in relation to each other, the space between the clamping plate elements changes. One clamping plate element comprises a surface which forms a plane on which the rolling body rolls from the released position to the clamped position.

The lifting ramps (5, 6) and the guiding recesses (9, 10) of the first and the second ramp plate (2, 3) are arranged so that they operate in opposite directions relative to each other. The roller bodies and the control elements are held in recesses (8) of a holding element (4) arranged between the ramp plates (2, 3).
