摘要:
A continuously variable power-branched transmission for a motor vehicle, including an input shaft, a variable speed drive unit having pairs of conical disks and a continuously variable transmission ratio, a gear system, and an output shaft. Two control clutches connect the variable speed drive unit and the gear system so that when going through the entire transmission ratio range of the power-branched transmission the adjustment range of the variable speed drive unit is passed through a plurality of times. The transmission also includes rotational speed sensors and a controller that determines whether a change in rotational speed is triggered by a change in the transmission ratio, and when it is not triggered by a change in the transmission ratio, the controller adjusts the variable speed drive unit so that the change in rotational speed not triggered by a change in the transmission ratio is compensated.

A plate-link chain for a motor vehicle drive system including conical pulleys. The chain includes a number of link plates hingedly connected with each other by rocker members. The rocker members extend transversely to the longitudinal direction of the plate-link chain and are situated in openings in the link plates. The rocker members have end faces for frictional contact with conical surfaces of disks of a belt-driven conical-pulley transmission, and the rocker member end faces are configured so that contact between the rocker member end faces and the conical surfaces of the disks takes place in the upper region of the end faces, relative to the height direction of the rocker members.

A hydraulic system including a multi-flow hydraulic pressure supply unit, especially a dual-flow hydraulic pressure supply unit, such as a pump, by which a volumetric flow of pressurized fluid is supplied to a hydraulic-fluid-operated device. A valve arrangement is provided either for switching between the individual pump flows or for interconnecting the individual pump flows.

A plate-link chain, in particular a toothed plate-link chain, made up of a plurality of plates that form sets of plates which are connected to neighboring sets of plates with a hinged connection. One rocker member of a hinged connection is connected to the plates of a set of plates through a connection opening, and two rocker members of neighboring sets of plates form the hinged connection. The rocker members can roll against each other at a roller profile, and the set of plates includes at least one guide plate. The rocker member includes a guide profile that is connected to a rocker profile through a first connecting profile and a second connecting profile. The guide plate has at least one connection opening which has an undercut or recess in the region of the first and/or second connecting profile.

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 branched power transmission having several transmission ratio ranges with a steplessly adjustable transmission ratio. A drive shaft is connected to both shafts of a variable speed unit through a distributor transmission, which shafts in turn are connected with the input shafts of a parallel gearbox through respective clutches. Two transmission ratio ranges differ from each other through the transmission ratio of an input shaft of the parallel gearbox and its output shaft. Additionally, the power-producing transmission can include an electrical machine. A further embodiment includes a variable speed unit, a first planetary transmission connected with a drive shaft, the input shaft of the variable speed unit and a connecting shaft, and a second planetary transmission that is connected with the connecting shaft of the output shaft of the variable speed unit and an output shaft, and an electrical machine that is non-rotatably connected with the connecting shaft.
摘要:
A conical disk array for a belt-driven transmission having sets of conical friction disks on the input and output sides that are operatively coupled to each other by an endless torque-transmitting means to transmit torque. At least one friction disk of the conical friction disk sets has a friction surface structure with ground grooves that are not coaxial with each other. A grinding device for grinding the friction surface has its axis of rotation skewed relative to the axis of rotation of the friction disk being ground. A method is for producing a friction surface structure on a friction disk of a conical disk array with a grinding device with which the rotating friction disk serves to form a non-coaxially-oriented friction surface pattern as the friction surface.
摘要:
A chain including identically-configured plate elements having at least one through opening that overlaps with through openings of preceding and following plate elements. The plate elements are interconnected with identically-configured rocker members that extend into the plate openings. The rocker members are in the form of pins having an asymmetric cross-sectional shape that includes rolling surfaces and contact point surfaces that engage with the plate opening surfaces. Outer end faces of the rocker members are crowned to provide contact points that are asymmetrically positioned relative to a pin longitudinal central axis. By reversing the rocker member orientation within the plate element through openings, randomization of chain contacts with chain-driven components is achieved, with improved acoustics. And by utilizing identical plate elements and identical rocker members parts manufacture is simplified, as are part inventory requirements.
摘要:
A transmission system including a shift mechanism for operating and controlling the transmission system. To automatically detect geometric characteristic values of the transmission system or of the shifting device a selector motor and a shift motor actuate a select or finger that is displaceably mounted in a selection-shift-passageway layout. Starting from an initial position whose coordinates within the selection-shift-passageway layout are unknown, the selector finger is displaced in the directions of shifting and in the directions of selection in order to detect paths of movement in the direction of selection or shifting. The selector finger is repeatedly displaced to establish the maximum paths of movement until the predetermined transmission geometric characteristic values are completely detected. Also disclosed are a control device for controlling a transmission system that includes a shift mechanism, and a method for controlling such a transmission system.
