Embodiment Construction

[0050] figure 1 Shown as gear gear transmission shifting device 2 ( figure 2 ) part of the synchronization device 1. The individual components are arranged coaxially around a transmission shaft (not shown). The idler gear, to which the cone 3 is fixedly connected radially and axially, is likewise not shown. An inner ring 4 , an intermediate ring 5 and an outer ring 6 are arranged axially offset from the cone 3 . In this case, the intermediate ring 5 has pins 7 which engage in conical cutouts 8 . The inner ring 4 and the outer ring 6 can be axially displaced via the inner toothing 9 , 10 on a synchronization hub (not shown) or can be fixed radially to the transmission shaft. If an axial pressure is applied to the outer ring 6 in this system, a frictional fit occurs so that the cone 3 receives the same rotational speed as the inner ring 4 and the outer ring 6 .

[0051] With the actuating mechanism according to the invention of the synchronization device 1 , axial forces c...

Abstract

The invention relates to a shifting device (2) of a gear wheel variable-speed transmission, comprising a shifting element (44) that can be axially displaced by a shifting actuating unit (17) relative to a transmission shaft. The invention further comprises at least one synchronizer ring (4, 5, 6), which is arranged between an idler gear supported on the transmission shaft and the shifting element (44), wherein an axial bearing (11) is arranged between the shifting element (44) and the synchronizer ring (4, 5, 6).

Description

technical field [0001] The invention relates to a shifting device of a range gear transmission, which has a shifting element and a synchronizing device, the shifting element can be displaced in the axial direction relative to the transmission shaft by a shifting operating unit and the synchronizing device is arranged on the shifting element Between the idler wheel (Losrad) supported on the transmission shaft. Background technique [0002] Shifting devices for gear transmissions usually have a shift actuating unit in the form of a shift fork, which is connected to a selector lever or a selector shaft. The selector fork engages positively in the sliding sleeve of the synchronizer, wherein the idler gear can be coupled via the coupling element to the intermediate shaft or the transmission main shaft. Many selector forks used in such shifting devices are connected in a rotationally fixed manner to a selector lever. As an alternative thereto, the selector fork, which is designe...
