Synchronizer classification
The synchronizer has a constant pressure type and an inertia type.
The synchronizer has a constant pressure type and an inertia type.
At present, all of the synchronous transmissions adopt an inertial synchronizer, which is mainly composed of a joint sleeve, a synchronous lock ring, etc., and is characterized by friction by means of synchronization.
The ring sleeve (locking angle) is provided on the ring gear of the engaging sleeve, the synchronizing locking ring and the gear to be engaged, and the inner tapered surface of the synchronous locking ring is in contact with the outer tapered surface of the gear ring to be engaged to generate friction. The locking angle and the taper surface have been properly selected at the time of design. The taper friction causes the toothed sleeve to be meshed to be rapidly synchronized with the ring gear, and at the same time, a locking action is generated to prevent the gear from meshing before synchronization.
When the inner tapered surface of the synchronous lock ring is in contact with the outer tapered surface of the gear ring to be engaged, the gear speed rapidly decreases (or rises) under the action of the friction torque to the same speed as the synchronous lock ring, and the two rotate synchronously, and the gear is opposite to the gear. The speed of the synchronizing lock ring is zero, and the moment of inertia also disappears. At this time, under the force of the force, the sleeve is unimpededly engaged with the synchronizing ring ring gear and further engaged with the ring gear of the gear to be engaged. Shift process.
