Problems solved by technology

[0004] The disadvantage of this system is that it rotates with the crankshaft and thus high centrifugal forces occur on the holding body and the vibrations of the engine can have a negative effect on the freewheel

Embodiment Construction

[0047] The present invention is used on starters that run continuously on one track. It is used to decouple the crankshaft or primary mass from the starter ring gear during operation via the freewheel.

[0048] figure 1 The working principle of the free wheel is shown in . This free wheel is made up of inner ring 1, outer ring 2, holding body 4, support 5 and is supported on the engine flange 3 of engine body by support 5. As a result, the freewheel does not rotate after starting and no high centrifugal forces act on the holding body and engine vibrations have no effect on the freewheel.

[0049] A starter ring / gear (not shown) is connected to the outer ring 2 and a crankshaft (not shown) is connected to the inner ring 1 . Before starting free wheel according to figure 1 Middle view a is open. This means that there is a gap 6 between the clamping body 4 and the inner ring 1 , so that no torque is transmitted between the inner ring 1 and the outer ring 2 via the clamping b...

Abstract

The invention relates to a freewheel, which is used in particular for permanently engaged starters, comprising an inner ring coupled to the crankshaft / the primary mass, an outer ring coupled to the starter ring, and a carrier accommodated on the engine block, on which carrier several clamping elements are accommodated in a pivotable / rotatable manner, which clamping elements are distanced from the inner ring in the decoupled state (idling) and are transferred into a coupled stated during starting as a result of a rotational motion of the carrier by a first stop arranged on the outer ring and transmit a torque between the inner ring and the outer ring, wherein the freewheel has means that support the pivoting motion of the clamping elements into the decoupled state and thus the decoupling of the freewheel after starting while the outer ring is stopped.

Description

technical field [0001] The invention relates to a freewheel, in particular for a starter of an internal combustion engine which runs continuously on a track and for decoupling a crankshaft or a primary mass from a starter ring gear during operation by means of a freewheel. In this case, the freewheel works in such a way that up to a certain torque, the rotational speed is transmitted between the crankshaft or primary mass and the starter ring gear or the starter shaft, and at an increasing torque no more torque is transmitted. Background technique [0002] Known from DE 3707283 C2 is a clamping body freewheel clutch with clamping bodies in the form of cams, which are arranged in the circumferential direction between an outer coupling part and an inner coupling part and between two side plates , wherein the clamping bodies are received by a clamping body cage which forms a driving connection with the side plate and in which the clamping bodies are inserted, which are radially...
