Problems solved by technology

[0006] It is also possible to connect the outer and inner conical rings directly to the synchronizer instead of a certain mutual torsionally fixed connection, however this would involve additional costs for designing a certain transmission geometry on the synchronizer
In addition, this design structure may lead to an increase in the unblocking force at high traction torques

Embodiment Construction

[0024] figure 1 and figure 2 Shown is a detailed view in cross section and a detailed view in longitudinal section of a multi-stage synchronizing module 10 of a transmission 12 with a synchronizer 14 rotatable about a drive axis A, a rotatable about a drive axis A A first-stage conical ring 16 , a second-stage conical ring 18 rotatable around the transmission axis A, and a third-stage conical ring 20 rotatable around the transmission axis A. The third-stage conical ring is arranged radially between the first-stage conical ring 16 and the second-stage conical ring 18 and can establish frictional connection with the first-stage conical ring 16 and the second-stage conical ring 18 . The conical rings 16 , 18 , 20 each have a friction surface 22 for establishing a frictional connection. These friction surfaces can at least partially be equipped with a special friction lining.

Abstract

The multiple synchronization components comprise a coupling element (24) and a synchronizer body (14) which is rotated around a gear axis (A). Three cone rings (16,18,20) are rotated around the gear axis, where a frictional contact is produced with two cone rings. The rotation movement is transferred to a gear wheel (38) of a shift gear box (12). An independent claim is also included for a shift gear box with a shift collar.

Description

technical field [0001] The invention relates to a multi-stage synchronous module of a transmission and a transmission itself. Background technique [0002] From the state of the art, transmissions, especially sleeve transmissions of motor vehicles, are well known and generally designed as synchronous transmissions with a synchronizing module. If a gear is engaged, in this type of transmission, a synchronizer, which is connected in a rotationally fixed manner to the drive shaft, is connected in a rotationally fixed manner to the gearwheel via a shifting sleeve with different axial directions. If another gear is engaged at this time, the synchronization module is first responsible for adjusting the speed of the synchronizer and the individual gearwheels before it allows connection via the selector sleeve. [0003] Typically the synchronization module comprises at least one conical ring. The conical ring can mesh with the synchronizer of the transmission and form a connection...
