General characteristics
The 6-speed manual transmission in the block with the leading axle has three shafts with four fixed gears mounted on the primary shaft and seven gears mounted on two secondary shafts. The maximum input torque is 200 Nm.
In traditional transaxles/gearboxes, the input shaft transmits torque to the output shaft, which is equipped with gears. The number of gears therefore determines the length of the transmission housing.
The 6-speed manual transmission in a block with a leading axle does not require an increase in the length of the housing to install six gears; this is achieved by using two secondary shafts. The use of two secondary shafts allows the gearbox in the block with the drive axle to be significantly shortened, which allows it to be installed in a more limited space.
The gears are divided between the two secondary shafts as follows:
- Secondary shaft 1: 1st, 2nd, 5th and 6th gears
- Secondary shaft 2: 3rd, 4th and reverse gear gears
The gears of all gears, including the reverse gear, are synchronized. The gears on the input shaft are fixedly attached to the shaft.
The secondary shafts and the primary shaft are supported by roller bearings (clutch housing), sealed ball bearings are used in the gearbox housing in the block with the drive axle.
The differential in both housings is supported by tapered roller bearings.
The center distance between the input shaft and the differential is 187.85 mm.
The weight of the gearbox in the block with the drive axle is approximately 46 kg; the overall length is 332 mm, including the clutch housing.
