A belt drive for a motor vehicle having at least two toothed pulleys () which are spaced apart from one another and having a toothed belt which wraps around them, wherein a positively locking connection is formed between a toothing system of the wraparound means and a toothing system () of the toothed pulleys (), which positively locking connection is of low-friction configuration by an anti-friction agent which acts between the toothing systems is provided. In order for it to be possible to configure a toothed belt inexpensively and without an anti-friction agent, the anti-friction agent is formed in the form of a lubricant-varnish layer () which is applied at least to a toothing system () of a toothed pulley ().

Belt drive for a motor vehicle

The invention relates to a drive wheel () of an auxiliary unit belt drive of an internal combustion engine, having a running casing () which is operatively connected to a traction mechanism, having a hub () which is rotationally fixedly connected to the drive axle of an auxiliary unit, and having a damping device (), which is arranged so as to act between the running casing () and the hub (), for reducing rotary oscillations, with the damping device () comprising a spring store () which is arranged so as to act between the running casing () and the hub (). In order that the running casing can be produced more economically, the invention provides that the running casing () is composed of a running part (), a driver part () and a spring receptacle (), with the running part () being rotationally fixedly and permanently connected to the driver part (), and wherein the driver part () can be or is connected in a form-fitting manner to the spring receptacle ().

The invention relates to a clamping device comprising a pivoting arm on which a clamping roll is rotatably arranged. In order to damp pivoting movements of the pivoting arm, a damping device is provided in the region of a pivoting axis X. Furthermore, the pivoting arm is supported by a tension spring device which ensures a frictional arrangement of the clamping roll on a traction mechanism, in the assembled state.

Tensioning device

A tensioner (') for a traction mechanism such as a belt, chain or the like, with a tensioning lever () which can be acted on by a helical spring (), can pivot about a stationary shaft and on which a tensioning element is provided for abutment against the traction mechanism to be tensioned. The helical spring () is held at its ends by spring receptacles () and a means () is provided for delimiting the spring excursion.

Tensioner for a traction mechanism

A tensioning device for a traction mechanism, particularly a belt or a chain, including a tensioning lever over which the traction mechanism is guided and on which a tensioning spring is disposed with one end thereof, the other end thereof being provided on a spring holder by which the tensioning device can be fastened to an external object. A holding pin () extends through the tensioning spring (), with the pin at one end () thereof being disposed in a fixed position on the tensioning lever () and at the other end thereof having a locking section () disposed on a locking element () provided on a spring holder (). The locking element can be adjusted between a locking position of the holding pin end (), in which the tensioning device () is fixed in a position with the pretensioned tensioning spring (), and a released position of the holding pin end (), in which the holding pin () is axially displaceable in the locking element (), and limited by a stop.

The invention relates to a rail () of a flexible drive, which rail () is intended to guide a drawing means (). A lubricant which is introduced into the rail () via the lubricant channel () brings about a pressure gap () which is formed between the inner side of the drawing means () and a guide face () of the rail (). Direct contact of the drawing means with the rail () is suppressed on account of the lubricant which is introduced into the pressure gap (), which has a friction-reducing effect.

Oil supply system for supplying oil to slide rails and guide rails

The decoupler for a drive wheel arrangement for an auxiliary unit of an internal combustion engine has a belt pulley connected to a flexible drive element and a shaft. A damping device is arranged between the shaft and the belt pulley and includes a spring. The belt pulley is connected to a damper cage, which is connected via at least one spring to a damper cage which is positioned such that it can rotate on the shaft.

Decoupler arrangement

Traction mechanism drive for an internal combustion engine, having a crankshaft gear wheel, at least one gear wheel which is arranged on a driven shaft, a wrap-around means and an electric machine which can be actuated in order to reduce rotational non-uniformities, the electric machine () having a rotor () which is arranged on the or a camshaft () and interacts with an immobile stator ().

Traction mechanism drive

A fastening element (,) such as a tensioning nut made of deep drawn steel sheet and having a threaded section (,) formed therein by rolling and on its outer peripheral surface (,), the fastening element comprises an integrally formed dog device (,) which starts from the end of the fastening element on which the threaded section (,) is arranged and comprises at least one tab-like section (,) which is bent over onto the outer peripheral surface (,) of the fastening element (,) which when viewed in axial direction, the tab-like section (,) may overlap the threaded section (,) at least partly, economic to manufacture and fulfills the requirements of light-weight construction and a particular advantage of the invention is that the dog device (,) has no influence on the threaded section (,).

Fastening element

The invention concerns an arrangement for mounting a shaft (,) comprising a shaft journal (,) arranged eccentric to a central longitudinal axis (,) of the shaft (,) on an end portion (,) of the shaft (,), said end portion (,) being supported by a first needle roller bearing (,) in a housing, and said eccentric shaft journal (,) being connected by a second needle roller bearing (,) to a movable part of a connecting structure. According to the invention, the outer ring of each needle roller bearing (,) is made as a deep-drawn bushing (,) which is shaped without chip removal and comprises rims (,) on each side, the diameter d of the inner edge of the outer rims (,) facing away from each other being smaller than the diameter D of the associated inner raceway. Due to this mirror-image arrangement of the two needle roller bearings (,), an axial displacement of the shaft (,) is prevented when the fixed bearing (,) fails.
