Description

Gear arrangement for commercial vehicle
Technical field
The present invention relates to a kind of gear arrangement for commercial vehicle, it can via drive shaft by vehicle motor with energy The mode of rotation drives, and has power shifting gear group, the cloth for being configured to multiple half lug-latch (Mehrfachsplitter) Set synchronization stopper part after power shifting gear group and the motility shift for rotation direction reversion commutation gear group and Output shaft can be driven the first vehicle bridge driver by output shaft.
Background technique
In well known power-shift transmission, half lug-latch of quadruple gear synchronous with five to six combines or half lug-latch of sixfold Gear synchronous with four to five combines.The synchronous gear of what gear arrangement had be unable to power shifting is more, commercial vehicle, preferably agricultural The kinetic current of commercial vehicle is more continually interrupted when accelerating.In farm work, so that agricultural commercial vehicle was being shifted gears The speed of loss is braked and therefore must restored again in unfavorable gear during journey.It, cannot in heavy farm work The synchronous gear transformation of power shifting is infeasible, because agricultural commercial vehicle may stop immediately in this case.One As for, compared to the switching of power shifting gear, the switching for being unable to the synchronous gear of power shifting is always more uncomfortable.
Summary of the invention
The task of the present invention is: propose a kind of gear arrangement for commercial vehicle, it has improved efficiency.
The task is addressed in the following manner according to the present invention, that is, power shifting gear group includes at least six edges The forward gear of one rotation direction rotation；Synchronous stopper part has multiple synchronous gears, these gears synchronized in gear are direct The synchronous gear of (durchgetrieben) of perforation transmission；Commutation gear group is arranged in front of output shaft and the rotation side for the gear group that commutates It is not interrupt kinetic current to reversion.
Commercial vehicle is preferably agricultural commercial vehicle.
By the quantity for improving the forward gear of power shifting gear group while improving and keeping off spreading range, it is possible to reduce synchronous The quantity of gear, and at the same time making Velocity character curve better adapt to working range, because can provide very for each synchronous gear The forward gear of multi-quantity.The reduction of synchronous gear leads to the reduction of cost and structure consumption.
This configuration makes power shifting gear group itself can be in a rotation direction not interrupt kinetic current Mode switches its forward gear.
Commutation gear group before being arranged in output shaft may be implemented not only when gear arrangement is shut down but also in commercial vehicle Rotation direction can be made to invert in the case where not interrupting kinetic current during traveling.
The overload protection for being directed to gear arrangement is formed before the gear group that commutates is located in output shaft.
The input terminal and output end for the gear group that commutates can be located in a straight line.
It is driven thus, it is possible to carry out directly perforation to forward gear, this is improved in efficiency when driving of advancing.
But it is also possible that being, the input terminal and output end for the gear group that commutates are not located in a straight line.
The synchronous gear of directly perforation transmission can be located in the main working range of gear arrangement.
Here, gear stage can design as follows, that is, make the direct perforation transmission, efficient gear covering speed changer dress Set the entire main working range with commercial vehicle.
In order to replace synchronous gear, it is necessary to kinetic current is interrupted, for this purpose, the clutch of the outlet side of power shifting gear group is broken It opens.
Second vehicle bridge driver can be driven by output shaft, the second vehicle bridge driver may be used as Das Vorderradfahrwerkmit Vorderradantrieb, and first Vehicle bridge driver may be used as rear driver.
Creeper gear gear group can be connected to before the output end of Synchronization Component.Thus it enables that forward gear slows down again.Thus Other gear combination is obtained, to yet further expand the use field of gear arrangement or commercial vehicle.
Power shifting gear group can have nine forward gears and synchronous stopper part tool is kept off there are three synchronous.
It is thus achieved that 27 forward gears (9 × 3) and equally realizing 27 and reversing gear.
Detailed description of the invention
The embodiment of the present invention is shown in the accompanying drawings, and carries out detailed description below.Wherein:
Fig. 1 shows the principle diagram of the first embodiment of gear arrangement；And
Fig. 2 shows the principle diagrams of the second embodiment of gear arrangement.
Specific embodiment
Gear arrangement use is in commercial vehicle, especially agricultural commercial vehicle, as in such as tractor or similar vehicles.
Gear arrangement has power shifting gear group 1.
It is disposed with synchronous stopper part 2 after power shifting gear group 1, is disposed with the commutation gear of motility shift again after which Group 3,3'.
Power shifting gear group 1 by being embodied as 9 grades of power shifting gear groups 1 realizes the advance of nine motilities shift Gear.Meanwhile the drive shaft 4 of power shifting gear group 1 is driven in a manner of being able to rotate by vehicle motor 5.
By the driving of output end 6 tool of power shifting gear group 1, there are three the synchronization stopper parts 2 of synchronous gear, wherein second is synchronous Gear 7 is the synchronous gear of direct perforation transmission, it is used for the main working range of gear arrangement.First synchronous gear 8 and third are same Step gear 9 is by indirect drive.
Driving commutation gear group 3,3' are realized by the output end 10 of synchronous stopper part 2.
In the embodiment shown in fig. 1, commutate gear group 3 input terminal 12 and output shaft 13 point-blank, to change It is direct perforation transmission and the cone for driving the first vehicle bridge driver 11, the rear car bridge driver for being preferably commercial vehicle to gear group Gear drive.
In the embodiment shown in Figure 2, the output end 12 and output shaft 13 for the gear group 3 that commutates not point-blank, thus Commutation gear group 3' is not direct perforation transmission.The gear group 3' that commutates drives the rear car of the first vehicle bridge driver 11, preferably commercial vehicle The taper transmission mechanism of bridge driver.
From commutation gear group 3,3', a branch leads to the second vehicle bridge driver 14, and the preferably front axle of vehicle drives Dynamic device, so as to realize a11wheel drive.
In the illustrated embodiment of gear arrangement, 9 × 2 × 3 gear grades, that is, 54 gear grades are always obtained.Power The gear grade of nine motilities shift of shift gear group 1 is all motility shift for each of three synchronism switching grades 's.In the case where being combined with unshowned creeper gear gear group, the gear that can also enable to switch is double.
