摘要： A gear has a hub with cut-off portions and outer splines as one unit. Thrust pieces are inserted in the cut-off portions for transmitting thrust between a shift sleeve and a synchronizer ring. The gear has a flange portion formed with supporting holes corresponding to the cut-off portions provided with a force-amplifying slope at synchronized member sides thereof. First end portions of the thrust pieces are inserted in the supporting holes. Second end portions thereof are formed with a side end surface for receiving friction torque from the synchronizer ring and with a pressure-receiving slope for transmitting the friction torque to the force-amplifying slope. The thrust pieces swing around centers in the supporting holes so that the second end portions swing in a rotational direction to contact the pressure-receiving slopes with the force-amplifying slopes to change the friction torque to the thrust acting on the synchronizer ring.

摘要： A synchronizing arrangement in a planetary gear (1) has an axially movable ring gear (22) which for various gearchange positions can be coupled to either of two coupling rings (9, 16), situated on their respective sides of the planetary gear (1), via synchronising rings (14, 20) which belong to these coupling rings, are capable of limited rotation relative to the ring gear and have external locking teeth (30, 31) to prevent gear engagement before synchronisation is achieved. The ring gear (22) is provided with two grooves (26, 27) which run round its inside and each accommodate a ring-shaped locking device (28) for transferring axial force to the respective synchronising ring at the time of gear engagement. The respective locking device is also situated in an external groove (32, 33) in the relating synchronising ring and can be compressed in the radial direction.

摘要： A booster mechanism is interposed between a hub of a Warner type synchronizing apparatus and a synchronizing ring to boost and transmit a pressure force caused by the movement of a coupling sleeve to a speed change gear side. There is also provided a rearward synchronizing mechanism for stopping the rotation of a drive shaft in such a manner that when the rearward synchronizing mechanism receives a pressure force caused by the reverse shift of the sleeve, it reverses and transmits the pressure force to the synchronizing ring for a synchronizing action, in addition to the booster mechanism on the forward speed change gear.

摘要： An improved single cone servo-action synchronizer apparatus having a hub fixed for rotation to a transmission shaft and an outer blocker ring and a ratio gear concentrically disposed on the transmission shaft. The blocker ring is formed with a plurality of longitudinally extending drive tangs which project into apertures formed in the hub. The drive tangs have an angled cam edge which converges outwardly at a first acute angle. The apertures have a complimentary angled side which is adapted for sliding engagement with the drive tang cam edge upon energization of the synchronizer apparatus. This sliding engagment causes the torque capacity of the synchronizer apparatus to be increased for a given input synchronizing force.
