Problems solved by technology

[0009] A disadvantage of the locking elements of the prior art is that they do not allow reliable centering of the sliding sleeve due to differences in temperature, axial movability or arrangement of these locking elements and require complex production
Furthermore, its assembly on the synchronization carrier and installation in the synchronization unit by means of non-lost-proof locking elements is complex

Embodiment Construction

[0028] like figure 1 The synchronizing carrier unit 5 of the synchronizing device of the shift transmission is shown with a synchronizing carrier 1 having a toothed ring 2 which forms the outer toothing 3 . The toothed ring 2 is arranged on a hub 4 of the synchronization carrier 1 . Ring gear 2 and hub 4 can be produced in one piece by sinter casting. Synchronizing body 1 engages in internal toothing 6 of sliding sleeve 7 by means of said external toothing 3 ( figure 2 ), the sliding sleeve is movably arranged along the tooth portion 3 to couple the gear gear not shown. In the coupled position shown, the internal toothing 6 of the sliding sleeve 7 engages in the toothing of the coupling body of the gearwheel.

[0029] In order to lock the sliding sleeve 7 in an intermediate position relative to the synchronizing carrier 1, a stop element 8 is provided, which is arranged in a receptacle 9 in the synchronizing carrier 1 and can be elastically engaged in the sliding In the s...

Abstract

The invention relates to a synchronizing carrier body unit (5) of a synchronizing device for a transmission of a motor vehicle, having a synchronizing carrier body (1), which has an outer set of teeth(3) for transferring torque to a sliding sleeve (7) and which has a holder (9), and having a locking unit (15), which has a housing (13) and locking element (8), upon which a spring (18) acts, for fastening the sliding sleeve (7) in relation to the synchronizing carrier body (1) and is arranged in the holder (9), wherein, in order to center the sliding sleeve (7), according to the invention, a resilient locking element (8) is arranged in a molded-on plastic housing (13).

Description

technical field [0001] The invention relates to a synchronizing carrier unit for a synchronizing device of a shift transmission, having a synchronizing body and a locking element for centering a sliding sleeve. Background technique [0002] Synchronizers are used in manual transmissions in order to shift between the individual gears in a comfortable manner. During the shifting process, the peripheral speed of the gearwheel is adapted to the peripheral speed of the transmission shaft by means of the various elements of the synchronization device, and a form-fit connection is then produced between the transmission shaft and the gearwheel. [0003] The transmission shaft is connected in a rotationally fixed manner to the sliding sleeve via a synchronizing carrier. This is usually achieved in that the synchronizing carrier is on the one hand positively connected to the transmission shaft in the circumferential direction via a wedge-shaped or toothed profile formed on its hub, a...
