摘要:
A dual-clutch group transmission having splitter, main and range groups. The range group is a planetary transmission with a ring gear, a sun gear and planetary gears that are supported by a carrier. Inner and outer transmission input shafts are connected to a respective first and second clutch. A main transmission shaft and shifting elements for engaging gears or forming frictional connections. Power-gearshifts, involving a shift of the range group, are enabled because the inner input shaft can be directly connected, via a shift element, to the main shaft. A hollow shaft extends coaxially over the main shaft and supports a loose wheel of a forward gear of the main group. The wheel can be rotationally fixed, via a shift element, to the hollow shaft which can be connected to the main shaft and the carrier by respective shifting elements.

A transmission brake (1) is described, where one transmission shaft (3) can be braked to carry out an upshift operation. The aim of the invention is to provide a transmission brake that is devoid of any hydraulic or pneumatic actuation device and that requires very little axial installation space. Such a transmission brake (1) has one electromagnetic actuation device (6, 7, 8) with which the friction elements (4, 5) of the transmission brake (1) can be pressed against each other for actuating the brake.

A device for the reduction of axial movement of the main shaft gears (2) in a transmission containing at least two countershafts. The main shaft gears (2) are held axially by two washer discs (3, 4) which is designed to be a pressing device (5, 6) on the main shaft (1) for at least one of the main shaft gears (2) against the washer disc (3) holding the main shaft gear (2) axially.

An electric conductor, in particular for connecting the starter relay and starter motor of a motor vehicle, includes an ignition device (5), which is in thermal contact with the conductor (1) and is intended, if a limit temperature is exceeded, for igniting and destroying the conductor (1). The conductor (1) includes one or more strands extending continuously between the ends (3) of the conductor. The ignition device is disposed on the conductor (1) so as to split apart these strands in the event of ignition.

The invention concerns a clutch (1) comprising a sliding sleeve (17) with selector teeth (19), two synchronizing rings (28, 29) situated on either side of the sliding sleeve (17) with locking teeth (30, 31) and friction surface (24, 25) which can be turned about a limited rotation angle in relation to the sliding sleeve (17) and two clutch bodies (20, 21) with clutch teeth (22, 23) and counter friction surface (26, 27), the clutch bodies (20, 21) interacting with the synchronizing rings (28, 29) wherein the sliding sleeve (17) is constantly connected with a gear element (3) in a way torsionally resistant and when engaged is connected to one of the clutch bodies (20, 21) via the selector teeth (19) and the clutch teeth (22, 23) with positive fit. In order to make possible a limited rotation angle between the sliding sleeve (17) and the synchronizing rings (28, 29) in a specifically narrow, externally guided, sliding sleeve (17), it is proposed that the synchronizing rings (28, 29) have several cams (32, 33) distributed over the periphery which engage in grooves (44) of the externally guided sliding sleeve (17) with a clearance thus defining the limited rotation angle, some of the cams (32) of one synchronizing ring (28) extending into the area of the other synchronizing ring (29) and vice versa.

In an apparatus for noise reduction and damping in ventilators of electric machines, in particular vehicular alternators, it is proposed that the ventilator support on the rotor shaft be effected by axially staggering inner rubber inlays on both sides and providing adjoining outer spring pressure elements such that the ventilator region is clamped, at least in the axial direction and preferably radially as well with an additional rubber ring. As a result, the transfer of resonant vibrations of the rotor to the ventilator are reliably avoided, and the noise emissions are decisively reduced.
摘要:
A shifting device and a method controlling shifting of transmission comprising main gearing and a splitter group which have a common countershaft. The splitter group is a double clutch transmission having two coaxially disposed input shafts, each of which can be connected, on the input side, to a motor drive shaft and, on the output side via a shiftable input stage, to the countershaft. Each input shaft of the shifting device is allocated a shift rail. Each shift rail is axially parallel and axially displaceable and is adjustably connected to the selector sleeve of an allocated shifting group via a shift fork and has engagement openings. A selector shaft is axially parallel to the shift rails and comprises selector fingers which engaging in the engagement openings of the shift rails. The selector shaft rotates, via a selection actuator, and is axially displaced, via a shifting actuator.
