Abstract

A sleeve-type freewheel having a sleeve with clamping ramps which are provided on the inner circumference and a plurality of needle-shaped or roller-shaped clamping bodies which are assigned to the clamping ramps, and a housing formed of lightweight metal and in which the sleeve is received, wherein the sleeve ( 2 ) has a radial flange ( 11 ), on which at least one radial projection ( 12 ) is provided, on which an axially projecting hook ( 16 ) is formed, and wherein a plurality of radially inwardly projecting contact sections ( 24 ) which are arranged distributed about the circumference are provided on the inner circumference of the housing ( 8 ), wherein the radial projection ( 12 ) is received between two contact sections ( 24 ) in the mounting position, wherein a groove ( 26 ) is formed between the contact sections ( 24 ) and a housing shoulder ( 25 ) which supports the radial flange ( 11 ) with the side ( 15 ) which has the hook ( 16 ), in which groove ( 26 ) the radial flange ( 11 ) is secured in a clamping manner with the hooked ( 16 ) being hooked on the housing shoulder ( 25 ) in the mounting position, in which the radial projection ( 12 ) bears against one contact section ( 24 ).

First claim

1 . A sleeve-shaped freewheel comprising a sleeve with clamping ramps provided on an inner circumference, a plurality of needle-shaped or roller-shaped clamping bodies allocated to the clamping ramps, a housing made from metal holds the sleeve, the sleeve has a radial flange on which at least one radial projection is provided on which an axially projecting hook is formed, a plurality of radially inward projecting contact sections distributed around an inner circumference of the housing, the radial projection is held between two of the projecting contact sections in a mounting position, a groove is formed in the housing between the contact sections and a housing shoulder supporting the radial flange with a side having the hook, and in the mounting position in which the radial projection contacts one of the contact sections, the radial flange is held in the groove in a clamped manner with the hooks hooking on the housing shoulder.

2 . The sleeve-shaped freewheel according to claim 1 , wherein there are several of the radial projections that contact a respective one of the contact sections in the mounting position.

3 . The sleeve-shaped freewheel according to claim 1 , wherein ones of the hooks are formed on respective ones of the radial projections, and the respective hooks hook onto the housing shoulder in the mounting position.

4 . The sleeve-shaped freewheel according to claim 1 , wherein the hook has a hook tip or hook edge that is directed opposite a direction of a respective stop face of an adjacent one of the at least one radial projections.

5 . The sleeve-shaped freewheel according to claim 1 , wherein ramp-shaped clamping sections that engage respective ones of the contact sections when inserted into the respective groove are provided on the radial flange adjacent to the respective radial projections.

6 . The sleeve-shaped freewheel according to claim 1 , wherein receptacles or openings for setting a mounting tool, with which the sleeve is turned into the mounting position after insertion into the housing, are provided on the radial flange or on one or more radial projections.

7 . The sleeve-shaped freewheel according to claim 6 , wherein an even number of the radial projections is provided, and a hook and a receptacle or opening are provided alternately on the radial projections.

8 . The sleeve-shaped freewheel according to claim 1 , wherein the sleeve is a sheet metal part on which the hook and the clamping sections and receptacles or openings are formed through embossing or punching.
