Problems solved by technology

However, multiple synchronization mechanisms are also structurally more complex, more difficult and significantly more expensive
Since there is absolutely no need to increase the synchronizing capacity in multi-shift transmissions, such complicated multiple synchronizing mechanisms are usually only used to ensure problem-free disengagement of the locking synchronizing components in all shifting situations of the motor vehicle transmission and to ensure The desired gear is reliably engaged

Embodiment Construction

[0036] figure 1 A conventional shift transmission 10 for a vehicle is shown in the region of the lock-up synchronizer assembly 12 known from the prior art. The locking synchronizing unit 12 comprises: a synchronizing hub 14 , which is mounted in a rotationally fixed manner on the transmission shaft and rotates in the circumferential direction about the transmission axis A; The shifting sleeve is arranged displaceably in the axial direction 18 relative to the synchronizing hub 14 ; the synchronizing ring 20 is used to couple the synchronizing hub 14 to the shifting gear 22 of the shifting transmission 10 via a frictional connection and a presynchronization unit 24 which engages on the shifting sleeve 16 and acts on the synchronizing ring 20 towards the axial shifting of the shifting gear 22 to be coupled when the shifting sleeve 16 moves axially Force F.

[0037] The synchronizer ring 20 has a locking toothing 26 and a friction cone 28 which according to figure 1 Formed as a...

Abstract

The invention relates to a locking synchronizing module of a shift transmission. The locking synchronizing module comprises a synchronizing ring which is rotatable about a shift transmission axis and has a locking engagement part and a frictional cone, a coupling disc which has a shifting engagement part and is in fixed connection with a shift gear which is rotatable about the shift transmission axis in a state that the locking synchronizing module is installed; and a mating cone which is adjacent to a friction cone of the synchronizing ring and in friction connection with a friction cone when the synchronizing ring moves towards an axis of the coupling disc, wherein the matching cone is connected to the shift gear of the shift transmission in a torsion resistant and axially-movable manner in a circumferential direction in the state when the locking synchronizing module is installed. Further, the invention also relates to a method for shifting the shift transmission with the lock synchronizing module.

Description

technical field [0001] The invention relates to a locking synchronizing assembly of a gearshift transmission, comprising: a synchronizing ring, which is rotatable around the transmission axis and has a locking toothing and a friction cone; a coupling disc, the coupling disc has a shifting toothing and is fixedly connected in the installed state of the locking synchronizing assembly to a gearwheel of the shifting transmission which is rotatable about the transmission axis; and a mating cone which adjoins the friction cone of the synchronizing ring And when the synchronizing ring moves axially towards the coupling disk, a frictional connection with the friction cone is formed. Background technique [0002] Coasting synchronized shift transmissions for motor vehicles are generally known from the prior art. In these transmissions it can occur under certain boundary conditions that, for example, the first gear or the reverse gear cannot be engaged or can only be engaged with dif...
