Embodiment Construction

[0013] figure 1 with figure 2 A clamping body freewheel 1 with an outer part 2 and an inner part 3 is shown along two sections. The outer part 2 has a cylindrical inner circumference 4 and the inner part 3 has a cylindrical outer circumference 5 , which enclose a gap space 6 , and clamping bodies 7 are distributed on the circumference and can be tilted in the circumferential direction. They are arranged one behind the other in the interstitial space 6 . The clamping bodies are pivotably accommodated at predetermined distances in the grooves 8 of the cage 9 , so that the outer part 2 and the inner part are rotated relative to each other in the first direction of rotation of the clamping body free wheel 1 At this time, a switch is made to a tilting mode in which the clamping body 7 pivoted with a small radius of action slides on the raceways 10 , 11 assigned to the inner part 3 and the outer part 2 . When the direction of rotation is reversed, the clamping body 7 , which is ...

Abstract

The invention relates to a clamping body freewheel (1) and to a method for producing same. The clamping body freewheel comprises an inner part (3) having a circular cylindrical outside circumference (5), an outer part (2) having a circular cylindrical inside circumference (4), and clamping bodies (7), which are accommodated in a gap (6) formed by the inside circumference (4) and outside circumference (5) and are arranged consecutively in the circumferential direction in a tiltable manner and guided in openings (8) of a cage (9). In order to be able to improve the installation of the clamping body freewheel (1) and simplify the inside circumference (4) of the outer part (2), the clamping bodies (7) are arranged in a radially inwardly open sleeve (13), and the clamping body freewheel (1) is introduced in the outer part (2) by means of the sleeve (13) in a rotationally fixed manner, wherein the clamping bodies (7) roll on an inside circumferential surface (17) of the sleeve (13).

Description

technical field [0001] The present invention relates to a clamping body freewheel and a manufacturing method thereof, the clamping body freewheel comprises an inner part having a cylindrical outer circumference, an outer part having a cylindrical inner circumference and an outer part arranged by the inner circumference and Clamping bodies arranged tiltably one behind the other in the peripheral direction in the gap space formed by the outer circumference and guided in grooves of the cage. Background technique [0002] A clamping body freewheel of this type, such as a freewheel clutch, is known, for example, from DE 10 2008 038 060 A1. In this case, the clamping bodies are held in the cage distributed along the circumference in the installed position. An inner circumferential surface, which forms the raceway for the clamping body, is provided on the inner circumference of the outer part by means of appropriate finishing and hardening methods, such as drilling and hardening. ...
