摘要： A synchronizer device for a manual transmission, having a shaft and a selector gear that is mounted on the shaft. The synchronizer device includes a hub, which can be connected to the shaft in a rotationally locked fashion, a slider sleeve, which is supported on the hub in a rotationally locked fashion, and can be slid in the axial direction, a locking element that is designed to limit the slidability of the slider sleeve in a locked position, a friction package, which has an outer synchro ring, an inner synchro ring, and an intermediate ring, which is positioned between the outer synchro ring and the inner synchro ring, with the outer synchro ring and inner synchro ring being able to rotate relative to each other, and a servo unit having a first servo surface on a first component and having a second servo surface on a second component, which rests against the first servo surface, and a torque between the first component and second component causes the first servo surface to slide along relative to the second servo surface, which produces an axially acting servo force on the friction package. According to this invention, the servo force is introduced into the friction package by the outer synchro ring and the outer synchro ring is able to rotate relative to the locking element.

摘要： A synchronizing device, for a vehicle gearbox, with a synchronizer body which can be mounted rotationally fixedly on an axial shaft, and a shift sleeve which is connected rotationally fixedly to the synchronizer body and can be moved axially along an outer periphery of the synchronizer body and which, to perform a synchronizing process, can be brought from a neutral position into rotationally fixed engagement in a first shift phase with an axially displaceable synchronizer ring and in a second shift phase with a clutch body adjacent to the synchronizer ring. During the first shift phase, the synchronizer ring can be moved in the direction of the adjacent clutch body by the shift sleeve using pressure pads arranged axially displaceably in the synchronizer body, and hence can be brought into frictional engagement with the adjacent clutch body for the purpose of pre-synchronization.

摘要： A strut-type synchronizer for coupling a gear to a rotating shaft includes a hub rotating with the shaft, a clutch ring rotatable with the gear, and a friction ring disposed between the hub and the clutch ring. The hub supports several struts for relative axial movement, as urged by an encircling splined sleeve through a detent, into engagement with the friction ring. The friction ring, which does not itself directly engage the sleeve, has a friction surface that is thus urged by the struts into engagement with a complementary friction surface of the clutch ring, whereupon relative rotation between the friction ring and the clutch ring ceases, the detent is overcome, and the sleeve's spline teeth engage complementary spline teeth on the clutch ring to fully engage the synchronizer. The friction surfaces include two axially-spaced frustoconical portions, by which an increased cone torque is achieved during synchronization.
