A hybrid module includes a first, motor-side pre-assembly group and a second, transmission-side pre-assembly group. A separating clutch is arranged between the motor-side pre-assembly group and the transmission-side pre-assembly group, via which the pre-assembly groups can be connected in a torque-transmitting manner.

Hybrid module for a drive train of a motor vehicle, hybrid unit and method for assembling a hybrid module

A plate-link chain having a plurality of link plates hingedly connected with each other by pairs of rocker members that each include two rocker members. The rocker members extend transversely to the longitudinal direction of the plate-link chain and are situated with play in openings in the link plates. The rocker members and the link plate openings each have respective curved contact surfaces along which the rocker members and the link plates bear against each other to transmit force. The rocker members include curved rolling surfaces along which the rocker members roll against each other during chain operation to transmit force. The play value between the rocker members and the opening in an adjacent link plate is less than 0.2 mm to minimize lateral vibrations of the chain during operation, to prevent contact of the chain with an enclosing housing and thereby reduce emitted noise.

Plate-link chain

A toothed plate-link chain having a plurality of link plates that form chain links in the transverse direction of the chain. The link plates of laterally adjacent chain links partially overlap, and the chain links are hingedly connected to each other by hinge pins that extend through receiving openings in overlap regions of the link plates. At least some of the link plates have plate teeth, and some of the link plates have a modified form to reduce the effect of impact impulses of the link plates on the tooth flanks of a toothed wheel about which the chain passes. As a result, the magnitude of the meshing impulses and the times during which they act on the toothed wheel are modified to thereby reduce structure-borne noise.

Toothed plate-link chain

A toothed plate for a toothed-plate plate-link chain, wherein the toothed plate includes two teeth, each having an inner flank, and an indentation between the teeth. The indentation includes a transition between a tooth flank and a curved innermost region. The transition has a convex curvature and is positioned at a junction of one of the inner flanks and the innermost region.

Toothed plate for a plate-link chain

A plate-link chain for a motor vehicle drive system. The chain includes a plurality of link plates articulatingly connected with each other by rocker members. The rocker members extend transversely to the longitudinal direction of the plate-link chain. The chain includes curved contact surfaces formed on the rocker members and on the link plates, along which the rocker members and link plates are in contact with each other to transmit force. The respective contact surfaces have a width that extends transversely to the longitudinal direction of the plate-link chain, and when considered in a side view running transversely to the width and in the longitudinal direction of the plate-link chain, they have an arc length. The contact surfaces have at least three regions along the arc length with different curvatures.

Plate-link chain, particularly for a motor vehicle drive system

A toothed chain, which has a multiplicity of toothed links and cover links articulatedly connected to one another by cradle pieces. The cradle pieces are arranged in cradle piece openings of the toothed links and cover links. The cover links form guide links situated at the outside at both sides of a longitudinal direction and hold the toothed links between them. The cover links are formed with link yokes, which have a respective opening for the cradle pieces, and with an upper and lower link web which connect the link yokes. An opening is formed in the region between the upper and lower link webs, which has, in plan view, a substantially trapezoidal shape with sides of substantially equal lengths and an upper side and lower side of different lengths. The upper side is assigned to the upper link web and the lower side to the lower link web.

Toothed chain, in particular for a vehicle drive

A plate-link chain composed of a large number of plates that form plate sets, where adjacent plate sets are hingedly connected to each other by pairs of rocker members. The rocker members of a rocker member pair have rolling surfaces that bear against each other. Some plate sets, preferably every second one, have a cover plate on their outwardly-facing sides, and the two rocker members associated with the plate set provided with the cover plates are received in receiving openings of the cover plates, and are pressed into them. At least one of the openings has relief cuts on both ends of a contact surface contacted by the rolling surface of the received rocker member, with the cover plate opening having a third relief cut.

A chain drive with at least two sprocket wheels provided with teeth having an evolvent spline, and a toothed chain that engages therewith, especially for a vehicle propulsion system, which toothed chain includes individual rows of link plates that have openings, wherein the link plates are movably connected with each other by rocker pieces penetrating the openings and have chain teeth. The chain drive is characterized in that the tooth flanks of at least one tooth of least one of the sprocket wheels are designed differently.

Low-noise chain actuation

A plate-link chain for a motor vehicle drive system. The chain includes a plurality of link plates hingedly connected with each other by rocker members that extend transversely to the longitudinal direction of the plate-link chain and are positioned in openings of the link plates. The rocker members and link plates each have curved contact surfaces. The rocker members also have curved rolling surfaces along which the rocker members roll against each other. The rocker members are shaped asymmetrically in the height direction, and the contact surfaces are provided on upper and lower contact surface regions. The rocker members also have at least two regions with different curvatures in the regions of their rolling surfaces.

Plate-link chain for a motor vehicle drive system

A plate-link chain for a motor vehicle drive system. The chain includes a number of link plates hingedly connected with each other by rocker members that extend transversely to the longitudinal direction of the plate-link chain and are positioned in openings of the link plates. Curved contact surfaces are located on each of the rocker members and link plates, along which contact surfaces the rocker members and link plates are in contact with each other to transmit power. The rocker members are shaped asymmetrically in the height direction and are provided in contacting pairs. The link plate openings include at least one inwardly-curved region that is located above a contact point line extending through contact points of contacting rocker members of adjacent rocker member pairs that roll against each other.

A plate-link chain composed of a plurality of plates that form plate sets, which are connected to an adjacent plate set with a hinge joint. At least some of the plates have a stopping means that limits bending of the plate-link chain in a direction opposite to the bend direction the chain undergoes when it passes over and around a pulley or a gear with which the chain comes into contacting engagement when the pulley or gear rotates.
