Gearbox autoboss v30 synchronizer

As the rotation of the transmission input   autoboss v30 shaft and the output shaft to the respective speed, the transform stalls aggregate exists the problem of a "synchronous". The two rotary speed is not the same as gear meshing force will inevitably impact collision occurs, damage to the gear. Therefore, the old-style transmission shift feet clutch "upshift downshift stay a while in the neutral position, in the neutral position, fuel door, so as to reduce the speed of the gear. However, this operation is relatively complex, difficult to grasp precisely. Therefore, the designer to create a "synchronizer", through the synchronization allows the gears to be engaged to achieve a consistent speed and smooth engagement.
Atmospheric pressure and inertial synchronizer.
All synchronous transmission using inertial synchronizer, it is mainly composed by the clutch in sync lock ring, it is characterized by relying on friction to achieve synchronization.Clutch in synchronization gear on the ring gear lock ring and be joined have chamfer (locking angle) within the cone synchronization lock ring to be bonding contact with the gear ring outside the cone friction. The locking angle with the cone has made appropriate choices in the design, the cone friction makes sets of teeth and the ring gear to be engaged quickly synchronization, at the same time will produce a locking effect and prevent gear engagement before synchronizing.
When synchronization lock ring tapered inner surface to be engaged gear ring outer tapered surface after contact, the effect   elm 327 of the friction torque gear speed quickly reduce (or increase) to a speed equal to the synchronization lock ring, both synchronous rotation, gear relative synchronization lock ring speed is zero, and therefore the moment of inertia also disappear when driven force, the clutch unhindered synchronization lock ring to ring gear engagement and further engagement with the ring gear to be engaged gear the shifting process.
(1) Why synchronizer
The rotational angular velocity consistent with the requirements of the the adjacent stalls mutual conversion should be taken when different operating steps same principle applies to the case of the mobile gear shift, only the former is to be joined to the ring gear and the clutch, while the latter is to be joined to the gear meshing point The line speed is consistent with the requirements, but are based on the speed of analysis is the same principle.
The shifting operation of the transmission, in particular from high-grade compared to the low-end of the shift operation complex, but it is prone to the interdental the impact of the teeth or splines. Can be set in the   launch x431 gx3  shift means in order to simplify the operation, and to avoid the interdental impact synchronizer.(2) the type and structure of the synchronizer
