An overrunning clutch clamping body for an overrunning clutch comprises a first contact surface and a second contact surface for contacting respective clamping raceways. The curvature of the contact surfaces deviates from zero in each direction. Each of the contact surfaces is configured symmetrically both to a first plane (E) extending normal to the axis of rotation of the overrunning clutch and to a second plane (E) that is perpendicular to the first plane (E), and the shape of the first contact surface corresponds to the shape of the second contact surface.

Overrunning clutch clamping body

A linear guide for transmitting a torque between a tubular housing, which is defined by a longitudinal axis and rotatable about the longitudinal axis, and a shaft, which is received in the housing and movable in the direction of the axis in relation to the housing, includes a bearing assembly received in the housing for support of the shaft and attached to the housing by swaging a housing portion. The bearing assembly has two bearing members and a set of rolling bodies disposed between the bearing members. One bearing member is constructed as bushing which is retained in the housing and defines a center axis which is oriented out-of-alignment with a normal upon a longitudinal shaft axis, and the other bearing member has a cup-shaped configuration to define a convex surface for support by a surface area of the shaft.

Linear guide

The invention proposes an intermediate lever () for a variable valve train of an internal combustion engine, said intermediate lever () comprising a loading end () and a pivoting end (), a cam contacting surface () and a support () for a resetting spring (), the loading end () extending on a front end of the intermediate lever () and comprising a sliding surface () for making contact with a lever-type valve opener, the pivoting end () being designed so as to cooperate with eccentric means for affecting a change of position of the intermediate lever (), and the cam contacting surface () being arranged between the loading end () and the pivoting end (), wherein the intermediate lever () is made of a thin-walled sheet metal and is manufactured substantially by a punching plus bending method and wherein the support () is arranged on an upper side () of the intermediate lever () in an edge region () adjoining the loading end () and has a convex portion extending towards the upper side () for contact by a leg () of a torsion spring constituting the resetting spring (), said support () being laterally delimited by two guide tabs ().

Intermediate lever for a variable valve train of an internal combustion engine

In a linear guide for transmitting a torque between a tubular housing, rotatable about a longitudinal axis, and a shaft, received in the housing and movable in the direction of the axis in relation to the housing, a plurality of axial rolling bearings are received in the housing in surrounding relationship to the shaft. The axial rolling bearings are disposed in two radial planes in axial spaced-apart relationship, wherein the axial rolling bearings in each of the two radial planes have each two bearing members and a set of rolling bodies disposed between the bearing members. One bearing member is constructed as bushing retained in the housing and defining a center axis which is shifted parallel at an offset to a normal upon a longitudinal shaft axis, while the other bearing member has a cup-shaped configuration to define a convex surface for support by a surface area of the shaft.
