Embodiment Construction

[0020] figure 1 Shown is a loose idler gear 1 , which is mounted on a shaft 2 with a needle bearing 3 . Also shown in this figure is a clutch body 4 which includes a shifting mesh 5 which meshes with a corresponding shifting mesh 6 of the movable idler 1 in the engaged state of the movable idler 1 , Such as figure 2 shown.

[0021] As mentioned earlier, in figure 1 and figure 2 With the shown conventional arrangement of the loose idler gear 1 , in this engaged state, a radially acting force component occurs due to the undercut force of the running overlock, which force component causes a pressure load on the bearing 3 . Because at the installed bearing 3, the load will be transmitted through the point-like or linear contact surface, thus generating local high pressure or stress. conditions could cause deformation of the bearing's rollers and / or indentations could form in the inner or outer rolling element raceways.

[0022] In order to avoid this situation, according t...

Abstract

The invention relates to a device for receiving radially acting forces in disk-freewheel of transmission, comprising components (7,8) used for receiving radially acting forces and arranged adjacent to a bearing (3) and a clutch body (4). The disk-freewheel (1) is rotatably mounted on a shaft (2) by the bearing (3) and the clutch body (4) is arranged on the shaft (2) in a rotation-proof manner and when the disk-freewheel (1) is at the joined state, a switch articulation part (5) of the clutch body (4) is engaged with a switch articulation part (6) of the disk-freewheel (1), wherein at the joined state, at least one part of the support surface of the disk-freewheel (1) is supported on the components (7,8).

Description

technical field [0001] The invention relates to a device according to the preamble of claim 1 for absorbing radially acting forces on a loose idler gear of a transmission. Background technique [0002] According to the prior art, the loose idler gear in transmissions is mounted axially displaceably on the shaft by means of bearings, which are designed, for example, as rolling bearings, slide bearings, etc. The forces transmitted here in the disengaged state are very low, and the individual components, that is to say loose gear, bearing and shaft, can move relative to one another. In order to engage the loose idler, the loose idler is moved axially in such a way that the switching clutch of the loose idler engages with the clutch body arranged on the shaft The toggle articulation engages. [0003] If the loose idler gear is engaged by means of the shift element for force transmission, a radially acting force component occurs due to the undercut force, which causes a pressu...
