The BTA brand Stub Axle, differential is an intermediary in the transmission of torque using gears directly from the input shaft to the secondary. So, both the input shaft and the secondary shaft are installed in the vehicle in this way - the front part, which belongs to the secondary shaft, enters directly into the groove of the rear part of the input shaft, whereby rotation is performed on the bearing in it. Both mechanical shafts, both primary and secondary, are connected only by the gears of the stub axle. It is important to know that the rotation in these devices is performed independently of each other. One drive gear is strongly fixed on the primary shaft. This part engages directly with the gear, which is part of the stub axle. On the secondary shaft, there is a block of gears, which, in fact, is not limited by anything and rotates freely. All gears of the secondary shaft are located on a specific section of the shaft.

The usage of stub axle differential

While gear shifting, the movement of the variable gear lever, special forks are set in motion. These elements are directly responsible for gear shifting. In turn, by means of the data, the device moves the clutch, and the special lock completely discards even the potential possibility of simultaneously switching on several gears of the car.
