DISK SYNCHRONIZER Russian patent published in 1999 - IPC

FIELD: transport engineering; car automatic transmissions. SUBSTANCE: synchronizer is designed for torque transmitting parts of automatic gearbox, in particular, for connecting gearbox shaft with gear wheel installed on shaft for operation. Disk clutch has external disk holder connected with engagement device, and internal disk holder. Pack of disks is installed between disk holders. When rotational frequencies of internal and external disk holders are equal, synchronizing torque is provided by means of disks. For this purpose external disk has device for connecting disk holder with device on gear wheel with geometric closing. EFFECT: increased synchronizing torque at light engagement force with prevention of jerks and noise at gear-shifting. 17 cl, 2 dwg
