Problems solved by technology

[0003] A disadvantage in the case of such a system with the main gear on the main shaft is the occurrence of undesired noises, so-called rattling noises, due to the axial and radial movability of the gears and external vibration excitations

Embodiment Construction

[0029] according to figure 1 The system according to the invention comprises a main shaft 1 , two countershafts 3 and 4 arranged parallel to the main shaft 1 , and a gear 2 which is rotatably arranged on the main shaft 1 as an overall gear by means of a damping sleeve 5 . The gear wheel 2 is in a rotationally driveable connection with the toothing of the countershafts 3 and 4 via the reverse gear wheels 12 and 13 .

[0030] The countershafts 3 and 4 are rotatable by means of roller bearings 14 and 15, but are mounted radially firmly in the transmission housing, whereas the main shaft 1 is mounted floating, ie with play, in the radial direction on the transmission housing. components not shown.

[0031] The gear wheel 2 is guided in the axial direction on the main shaft 1 by thrust disks 16 and 17 . In the radial direction, the gear wheel 2 is supported on the main shaft 1 by means of a damping sleeve 5 . The damping sleeve 5 consists of a rigid outer slip ring 6 and a flexi...

Abstract

The present invention relates to an arrangement of a gearwheel (2) on a main shaft (1) of a transmission with at least two idler shafts (3, 4), wherein the gearwheel (2) is configured as a sum wheel or gear wheel, and wherein the gearwheel (2) is connected to the idler shafts in a rotationally drivable manner and is arranged in a radially movable manner between the idler shafts (3, 4). According to the invention, the arrangement has a damping bush (5) which is arranged between the gearwheel (2) and the main shaft (1) and consists of a hard outer sliding ring (6) and of the elastomer part (7) which is connected fixedly to the outer sliding ring (6).

Description

technical field [0001] The invention relates to a gear system according to the preamble of claim 1 on the main shaft of a transmission with at least two countershafts, and to a damping sleeve according to claim 11 for use in said system. Background technique [0002] It is known that in the case of transmissions with a main shaft and two countershafts, the load balancing between the power flows takes place via the two countershafts. For this purpose, the gear wheel, which is also referred to as the total gear and engages in the toothing of the countershaft, is arranged radially movable relative to the main shaft and is guided radially by the toothing of the countershaft. center. The axial guidance of the main gear, which is designed as a range gear in the gearshift transmission, takes place, for example, via a thrust plate arranged laterally on the main shaft. [0003] A disadvantage of such a system with the main gear on the main shaft is that undesired noises, so-called ...
