Embodiment Construction

[0015] Transmission arrangements are used in commercial vehicles, in particular agricultural commercial vehicles, like for example tractors or the like.

[0016] The transmission arrangement has a power shift group 1 .

[0017] A power-shiftable reversing gear group 3 is arranged downstream of the power-shifting gear group 1 , and a synchromesh component 2 is also arranged downstream of this power-shiftable reversing gear group.

[0018] 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 .

[0019] The drive of the shift group 3 is realized by the output terminal 6 of the power shift group 1 .

[0020] The input end 12 and the output shaft 13 of the reversing gear group 3 lie on a straight line, so that the reversing gear group 3 is directly through-driven.

[0021] The output 6 of t...

Abstract

The invention relates to a transmission device for a commercial vehicle that can be driven in a rotatable manner by a vehicle engine (5) via a drive shaft (4) and has a power shifting gear set configured as a multiple half gear (1), the synchronous gear member (2) disposed behind the power shifting gear group and the power shifting reverse gear group (3) for the rotational direction reversal and the output shaft (10) can be driven by the output shaft The first axle drive (11). The power shift block includes a forward gear that rotates in a rotational direction. The synchronizing member has a plurality of synchronizing gears (7, 8, 9), and each of these synchronizing gears is a synchronous gear (7) that directly penetrates the transmission. The power shifting reverse gear is disposed between the power shifting gear and the synchronous gear member, wherein the reverse direction of the reverse gear is reversed without interrupting the power flow, and wherein the reverse gear (3) The inputterminal (12) and the output terminal (13) are located on a straight line.

Description

technical field [0001] The invention relates to a transmission arrangement 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 ...
