Manual box of a gear change (Manual transmission)

Site of an identification plate on a transmission

Identification number begins a transmission code

The gear change box is placed in картер, cast of an aluminium alloy and attached by bolts by the left end of the engine. The block consists of a transmission, the main transfer and differential. The type of a box of a gear change is specified on the identification plate attached to it (address to illustrations).
The rotary moment from коленвала is transferred through coupling to an entrance shaft of transmission which rotates on ball-bearings. From an entrance shaft the drive is transferred to a target shaft which rotates on the roller bearing (the right end) and the ball-bearing (the left end), and further - to a conducted gear wheel of the main transfer, lateral gear wheels of differential and power shafts. Rotation of satellites on their shaft allows an internal wheel at movement on turn to rotate more slowly the external.
The target shaft costs in parallel entrance and приводному to shaft, a teeth of gear wheels of shaft of transmission is in constant gearing. In neutral position of a gear wheel of a target shaft rotate freely, and the drive to the main transfer is not transferred to a conducted gear wheel. The manual box of a gear change has five forward transfers (all are synchronised) and a backing.
The transfer choice is carried out by means of the lever attached to a floor and draught.
The rod inside Manual transmission forces a corresponding plug of inclusion of transfer to move sliding муфту the synchronizer on a shaft therefore the gear wreath of the necessary gear wheel is hooked with a nave муфты the synchronizer. As naves of synchronizers have шлицевое gearing with target shaft, the drive is transferred to a shaft. The synchronizers providing fast and smooth change of transfer, consist of the blocking rings, supplied подпружиненными crackers of a nave and муфты.
