Problems solved by technology

[0004] Since the synchronization ring is subject to function not only in the axial direction but also in the circumferential direction and must be adjusted relative to the hub (and thus also relative to the sliding sleeve and the escape wheel), it cannot be reliably prevented: the synchronization ring is out of control The ground moves relative to the hub and sliding sleeve and is excited to vibrate here
The vibrations lead to internal stresses in the synchronizer ring itself and also to an uncontrolled impact of the synchronizer ring against the surrounding components in the transmission where it can be further excited to vibrate
In addition, vibrations can be excited by the uneven running of the transmission shaft, which is intensified by the trend towards a small number of cylinders in internal combustion engines used in motor vehicles, three-cylinder engines are not as smooth as four-cylinder engines

Embodiment Construction

[0023] exist figure 1 In , a synchronizing assembly 5 is shown, which serves to connect one or more transmission gears (not shown) in a rotationally fixed manner to a transmission shaft (also not shown), as is generally known. The synchronizing unit comprises a hub 10 (synchronizing body), which is arranged in a rotationally fixed manner on the transmission shaft by means of a hub toothing 12 . The variator shaft extends along a central axis M which is at the same time the center and axis of rotation for the variator gears and the synchronizing assembly 5 .

[0024] Transmission gear as floating wheel Set on the transmission shaft. When one of the gears associated with the corresponding transmission gear is to be used, this transmission gear must be connected to the transmission shaft in a rotationally fixed manner. This is done here by means of a synchronization device of the type according to US 2 221 894, which is known per se and will be explained below only in terms o...

Abstract

The invention relates to a synchronization component, and the synchronization component is provided with a hub (10), at least one pressure bearing member (30) supported on the hub (10), and at least one synchronizing ring (20), wherein the pressure receiving member (30) is provided with a plurality of centering faces (40, 41, 42) directly resting on at least two abutment faces disposed on the synchronizing ring (20) ( 50, 51), wherein at least one centering surface (40) rests on a radially and outwardly directed abutment surface (50) and at least one further centering surface (41) abuts against the abutment surface (51) radially and inwardly.

Description

technical field [0001] The invention relates to a synchronizing assembly having a hub, at least one pressure part mounted on the hub, and at least one synchronizing ring. Background technique [0002] Especially in motor vehicles, synchronization devices of the type disclosed in US 2 221 894 are frequently used. In this case, a hub, which can also be referred to as a synchronizing body, is mounted in a rotationally fixed manner on the shaft of the transmission. A sliding sleeve, which is displaceable in the axial direction, is arranged in a rotationally fixed manner on the hub. The sliding sleeve serves to produce a rotationally fixed connection to the transmission gear, which is mounted on both sides of the hub in a rotationally fixed manner on the transmission shaft. For this purpose, the gear is provided with shifting teeth, onto which an edge section of the sliding sleeve can be slid. [0003] Before the sliding sleeve engages in the switching toothing, the rotational...
