Problems solved by technology

Generally speaking, compared to the switching of power shift gears, the switching of synchronous gears that cannot be powered shifted is always more uncomfortable.

Embodiment Construction

[0023] Transmission arrangements are used in commercial vehicles, in particular agricultural commercial vehicles, like for example tractors or the like.

[0024] The transmission arrangement has a power shift group 1 .

[0025] The power shift group 1 is followed by a synchromesh component 2 , followed by a power shiftable reversing group 3 , 3 ′.

[0026] Nine power-shiftable forward gears are realized by means of the power-shift gear group 1 embodied as a 9-stage power-shift gear group 1 . At the same time, the drive shaft 4 of the power shift group 1 is rotatably driven by the vehicle engine 5 .

[0027] The output 6 of the power shift group 1 drives the synchromesh part 2 with three synchronous gears, wherein the second synchronous gear 7 is a direct through-drive synchronous gear which is used in the main operating range of the transmission arrangement. The first synchronous gear 8 and the third synchronous gear 9 are indirectly driven.

[0028] The drive of the shift ...

Abstract

The invention relates to a transmission for a commercial vehicle. The transmission can be driven by a vehicle engine (5) through a driving shaft (4) in a rotatable manner, and is provided with a powershifting gear set (1) configured as a multiple half gear, a synchronous gear member (2) disposed behind the power shifting gear set (1), a reversing gear set (3, 3') for power shifting for reversingrotation, and an output shaft (13). A first axle drive (11) can be driven by the output shaft. The power shifting gear set (1) includes at least six forward gears that rotate in one rotational direction. The synchronous gear member (2) has a plurality of synchronous gears (7, 8, 9), one of which is a synchronous gear (7) that directly penetrates the transmission. The reversing gear set (3, 3') isarranged in front of the output shaft (13), and reversing of the rotation direction of the reversing gear set (3, 3') does not interrupt the power flow.

Description

technical field [0001] The invention relates to a transmission device for a commercial vehicle, which can be rotatably driven by the vehicle engine via a drive shaft and has a power shift group configured as a multiple half gear, arranged in the power The synchromesh components downstream of the shift group and the power-shiftable shift group for reversal of the direction of rotation as well as the output shaft from which the first axle drive can be driven. Background technique [0002] In known powershift transmissions, a quadruple half gear is combined with five to six synchronized gears or a sextuple half gear is combined with four to five synchronized gears. The more the transmission arrangement has non-power-shiftable synchronized gears, the more frequently the power flow of the commercial vehicle, preferably an agricultural commercial vehicle, is interrupted during acceleration. When working in the field, the agricultural commercial vehicle is thus braked during the s...
