Embodiment Construction

[0024] figure 1 Schematically depicts a plan view of a transmission 1 according to a preferred embodiment of the present invention, the transmission comprising an input shaft 10, a main shaft 12 having an input end 12' and an output end 12", and a first intermediate shaft 14 and a second Intermediate shaft 16. The input shaft 10 and the main shaft 12 are coaxially arranged one after the other and can be directly connected to each other. The intermediate shafts 14, 16 are arranged on the sides of their respective input shaft 10 and main shaft 12 to substantially Parallel to each other and extending substantially along the length of the input shaft 10 and the main shaft 12, the area adjacent to the input shaft constitutes the split portion S, and the area adjacent to the main shaft is the main portion H. The input shaft 10 is arranged to receive a The power of the engine of the truck, etc.) rotates.

[0025] The main shaft 12 in the main part H supports a first gear 24 , a seco...

Abstract

The present invention relates to a transmission for a motor vehicle comprising an input shaft (10) which is arranged for rotation by the driving power from an engine of the vehicle and adapted to bearing at least one disengageable gearwheel (20, 22), a mainshaft (12) adapted to bearing gearwheels (24, 26, 28), a first intermediate shaft (14) adapted to bearing gearwheels, at least one of which isa disengageable gearwheel (30), the respective gearwheels on the mainshaft and on at least the first intermediate shaft being adapted to meshing with one another in pairs, one gearwheel in each pair being a disengageable gearwheel, and a second intermediate shaft (16) adapted to bearing a disengageable gearwheel (40), the mainshaft (12) being adapted to being rotated by power transferred from theinput shaft, the first and second intermediate shafts (14, 16) being so arranged that the respective disengageable gearwheels (30, 40) on these shafts are adapted to meshing with one another, and a gearwheel (20) on the input shaft (10) being adapted to meshing with the gearwheel (40) on the second intermediate shaft (16) so that, during operation, the mainshaft is caused to rotate, in the opposite direction from the input shaft, by power transferred from the first intermediate shaft (14). The invention also relates to a motor vehicle comprising said transmission.

Description

technical field [0001] The invention relates to a transmission for a motor vehicle according to the preamble of claim 1 . The invention further relates to a vehicle comprising a transmission according to claim 10 . Background technique [0002] Heavy duty trucks and buses require transmissions with a large number of gear differences (eg, up to 14 gear differences), however, light trucks and the like are often fitted with transmissions with fewer gear differences. [0003] Traditional gearboxes work in this way, drive power from the engine is transferred to the input shaft, via gears, this drive power is transferred from the input shaft to the intermediate shaft, and from the intermediate shaft, power is transferred to the main shaft, and via the output shaft to the propulsion shaft . The number of gears in the main transmission varies, but is most commonly three or four synchronized gears. By connecting additional gears of various types to the vehicle's main gearbox, the ...
