摘要:
A device for damping rotary oscillations in a drive train with a freewheel clutch (27) located between a pulley (25) and a rotor hub (26) is provided. The hub (26) is connected to an input shaft of an auxiliary unit, and the pulley (25) is connected to a crankshaft via a traction means, and the freewheel clutch (27) has an inner ring (34), which surrounds the hub (26) while being fixed thereto, and includes an outer ring (35), which surrounds the inner ring (34) with radial play and which is fixed to the pulley (25). At least one locking element (36) that is actuated by centrifugal force is provided in the inner ring (34), and at least one locking receptacle (37) is provided in the outer ring (35).

A clamping device for the positional fixing of a vehicle steering column which can be adjusted in its length and/or inclination has a clamping disc and a plurality of rolling bodies, with clamping ramps for the rolling bodies being formed on the surface of the clamping disc, wherein the rolling bodies each make contact with one of a plurality of separate contact elements arranged in a common plane.
摘要:
Clamping device, especially for a steering column, with a first ramp plate, which can rotate relative to a second ramp plate between a released position and a clamped position by changing a distance between the ramp plates is provided. The first ramp plate (2) and the second ramp plate (3) each have at least two lifting ramps (5, 6) arranged in the circumferential direction for roller bodies and at least one guiding recess, and more preferably two diagonal guiding recesses (9, 10), in the plane of the ramp plates (2, 3) for control elements. 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).
摘要:
A device for damping torsional vibrations in a drive train of a traction drive connecting an internal combustion piston engine and an auxiliary unit, comprising an overrunning clutch (5,30,48) arranged between a driving pulley (2,25,42) and an input shaft (1) of the auxiliary unit or between a crankshaft and a driven pulley of the internal combustion piston engine, characterized in that the overrunning clutch (5,30,48) comprises an inner or outer ring (8,9,28,29,50) made of sheet metal without chip removal on which locking ramps cooperating with locking rollers (10,30a,48a) are formed, and the inner or outer ring (8,9,28,29,50) extends at least on one side beyond a region of the locking ramps to form a raceway for a rolling bearing (6,7,31,32,45,49).
