Description
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.
Thus the task is addressed according to the present invention, that is, motility shift is connected to before power shifting gear group
Commutate gear group, and rotation direction reversion is not interrupt kinetic current, and power shifting gear group is by least six along a rotation direction
The forward gear of rotation, and synchronous stopper part has multiple synchronous gears, and it is direct perforation transmission that these, which synchronize a gear in gear,
(durchgetrieben) synchronous gear.
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 that can not interrupt the side of kinetic current along a rotation direction
Formula switches its forward gear.
Commutation gear group before being arranged in power shifting gear group may be implemented not only gear arrangement shut down when and also
Commercial vehicle can be such that rotation direction inverts during travelling in the case where not interrupting kinetic current.
Because commutation gear group only needs to adapt to the peak torque and possible starting torque of vehicle motor, it can be with
It is designed smaller.
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.
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.
Creeper gear gear group can be connected to before the output end of synchronous stopper part.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 is able to detailed description below.Unique attached drawing shows change
The principle diagram of fast device device.
Specific embodiment
Shown in gear arrangement use in commercial vehicle, especially agricultural commercial vehicle, as such as tractor or similar vehicle
In.
Gear arrangement has the commutation gear group 3 of motility shift.
It is disposed with power shifting gear group 1 after the commutation gear group 3 of motility shift, after this power shifting gear group
It there also is provided synchronous stopper part 2.
The drive shaft 4 of the commutation gear group 3 of motility shift is driven in a manner of being able to rotate by vehicle motor 5.Here, changing
It is parallel to each other to the input terminal 12 and output shaft 13 of gear group 3, so that commutation gear group 3 is not penetrate through transmission directly.
The power shifting gear group 1 for being embodied as 9 grades of power shifting gear groups 1 is driven by the output end 13 of commutation gear group 3, passes through it
Realize the forward gear of nine motilities shift.
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 major working range of gear arrangement.First synchronous gear 8 and third
Synchronous gear 9 is driven indirectly.
The output end 10 of synchronous stopper part 2 drives the first vehicle bridge driver 11, preferably commercial vehicle rear axle driving
The bevel gear transmission of device.
From the second synchronous gear 7s of commutation gear group 3, a branch leads to the second vehicle bridge driver 14, preferably commercial
The front truck bridge driver of vehicle, so as to realize a11wheel drive.
In the illustrated embodiment of gear arrangement, the advance not only for commercial vehicle travels and for retreating traveling all
Obtain 9 × 3 gear grades.It is each in the gear grade gearshifts level synchronous for three of nine motilities shift of power shifting gear group 1
It is all that motility is shifted gears for a.
