The invention relates to a commercial-vehicle transmission having an idler shaft (15) which can be decoupled in the direct gear. In order to realize a large number of gears, two input constants (17, 18) are provided, the force flow running via both input constants (17, 18) in a forward gear.

A variable-speed gear wheel transmission is proposed, comprising at least two input shafts (11, 12), which can be connected to a drive shaft (10) via at least two power-shift transmissions (K1, K2), comprising gear wheels disposed in gear wheel levels (E1, E2, Z1-Z5), and comprising an output shaft (13), which can be operatively connected to the input shafts (11, 12), and further comprising at least two sequentially shiftable forward gears (V1-V9) and a shifting device (17), which is provided in order to shift one of the gear wheel levels (Z1) as an input constant for forming at least one gear (V1, V2) and as a gear wheel pair for forming a further gear (V8, V9).
摘要:
The vehicle transmission (10) has a first component transmission (11) and a variable-ratio gear unit (12). In selected gearspeeds, power branching takes place to the countershaft (15), on the one hand, and to the main shaft (23), on the other hand. The power paths are superimposed in these gearspeeds bay means of the variable-ratio gear unit (12). In a power path, direct transmission takes place without the intermediate connection of gearwheels so that improvements in efficiency occur. In the direct gearspeed it is possible to decouple the countershaft (15) selectively via a control device or optionally couple it via the input constants (17, 18).

Prior art twin-clutch transmissions require a large radial and/or axial installation space and a high number of necessary transmission elements, particularly shift elements. According to the invention, a transmission of an input torque ensues in a first forward speed while coupling the first partial transmission, which has countershaft (16), to the second partial transmission, which has the countershaft (26), via a intermediate stage (33, 34, 35). The gearwheel of the intermediate stage (34, 35) can be used in a multifunctional manner for additional forward speeds in which only one partial transmission is actuated. The inventive twin-clutch transmission is for use in motor vehicles, particularly those equipped with a standard transmission.

The invention relates to a double clutch gear for a rear axle power transmission or for four-wheel drive and to a control motor which is frontally mounted in the longitudinal direction thereof. The bearings (15, 90, 96, 97) of the central shafts (12, 80) of the inventive double clutch gear are arranged in X-shape.

The invention relates to a toothed-wheel variable-speed transmission comprising: at least two power shift clutches (K1, K2), toothed wheels arranged in toothed wheel planes (E1, E2, Z1 - Z4), and an input shaft (10) and an output shaft (19) which can be actively interconnected by means of the at least two power shift clutches (K1, K2) arranged in parallel in the energy flow, and by means of the toothed wheels arranged in the toothed wheel planes (E1, E2, Z1 - Z4). According to the invention, the toothed-wheel variable-speed transmission comprises at least six forward gears (V1 - V6) that can be continuously sequentially power-shifted.

The invention relates to a power shiftable group transmission having a double clutch (1). This power shiftable group transmission has a high number of gear speeds and is suitable in particular for utility vehicles. A split group, a direct gear speed, a main group (100) and a hollow shaft (96) are provided on a countershaft (14). Between gear speeds which are brought about by changing the input constants (E1, E2) within the split group without the transmission ratio stage in the main transmission (100) changing, it is possible to shift without interruption in the tractive force. In addition, it is possible to shift without interruption in the tractive force between two adjacent gear speeds which are produced by changing the transmission ratio within the main group (100).
