Difference in torque fast reaction can occur to antero posterior axis in problem, the differential transmission systems, redistribute the torque of antero posterior axis, guarantee
Engine is in relatively reasonable torque point always, has not only been able to achieve pre-post difference speed but also can be carried out the switching of two drive 4 wheel drivens, it can be achieved that right
The adaptation of different road conditions.When manipulating shift mechanism, the synchronizer 5 can be respectively with the 4 wheel driven driving gear 4 or institute
It is driven driven gear 6 after stating to engage, realizes two drives or the switching of 4 wheel driven.
As shown in Figure 1, the differential transmission systems include the torsional differential gear 13 being arranged in the transfer casing 3, it is described
Also rotation is provided with the preceding jackshaft 8 and rear intermediate shaft 15 parallel with the power input shaft 1, the Torsen in transfer casing 3
The output end of differential mechanism is separately connected the preceding jackshaft 8 and the rear intermediate shaft 15, is equipped with forward pass on the preceding jackshaft 8
Dynamic driving gear 2, is equipped with rear transmission gear 14 on the rear intermediate shaft 15, it is described after transmission gear 14 with it is described
Transmission driven gear 6 engages afterwards；The driving front driving gear 2 is sequentially connected the driving front gear train；The Torsen is poor
The shell of fast device 13 is provided with 4 wheel driven driven gear 12, and the 4 wheel driven driving gear 4 is engaged with the 4 wheel driven driven gear 12.Institute
It states preceding jackshaft 8 and the rear intermediate shaft 15 and the torsional differential gear 13 is equipped with by spline.
As shown in Figure 1, the driving front gear train includes rotating the driving front passive tooth of suit on the front propeller shaft 9
10 are taken turns, the engaging sleeve 11 with the driving front driven gear 10 cooperation, the driving front quilt are also equipped on the front propeller shaft 9
Moving gear 10 is engaged with the driving front driving gear 2.When manipulating shift mechanism, the engaging sleeve 11 can be with the forward pass
The dynamic engagement of driven gear 10 disconnects, and realizes two drives or the switching of 4 wheel driven.
The torsional differential gear 13 is Torsen Type B differential mechanism.13 (the Torsen of torsional differential gear
Differential), also referred to as Torsen formula no-spin lockup, it is high using the irreversibility principle and the flank of tooth of Worm Wheel System
Friction condition makes differential mechanism be automatically locked according to the size of its internal differential torque (i.e. the interior friction torque of differential mechanism) or pine
Open, i.e., when differential torque is smaller in differential mechanism from differential action, and when differential torque is excessive in differential mechanism differential mechanism incite somebody to action from
It is dynamic locked, the handling capacity of automobile can be effectively improved in this way.
The torsional differential gear 13, common is divided into following four kinds:
(1) Torsen A type, also relatively purely, without built-in friction plate, all limits are sliding next for this torsional differential gear 13
From in curved tooth.The sliding principle of the limit of Torsen A type is exactly the latching characteristics of curved tooth, and the radian of curved tooth can change, and limiting sliding ability can also
To change.
(2) Torsen Type B, the gear in Torsen Type B is all parallel, and joined friction plate.The sliding ability one of his limit
Part is self-locking from curved tooth, and a part comes from friction plate.The axis that the driving force of friction plate generates when rotating from meshing gear
Xiang Li starts running inside differential mechanism when occurring sliding rotational speed difference, and the axial force that gear rotation generates pushes sun gear, leads to
Friction plate is crossed to rub to form the sliding effect of limit.
(3) Torsen c-type, Torsen c-type are equivalent to a sandwich structure, and one of sun gear becomes gear ring, gear ring set
Planet carrier covers sun gear, and the inside and outside output of intermediate input is successively exported by hollow shaft.It can be seen that sun gear and gear ring are different
Sample is big, and this structure can be used only in center differential, realizes the function of front and back power distribution.The sliding principle of its limit and Torsen B
Equally, two aspects that are from that curved tooth is self-locking and end face rubs.
(4) its moulding of novel Torsen is compared as Torsen B, but it realizes two sun gears with three groups of six roots of sensation planetary gears
It is not equal big, it is seen that novel Torsen is as c-type, it is also to be specifically used to realize that 4-wheel driven car front and back power distributes, so he is only
The position of center differential can be used in.
The transmission connection of inter-axle shaft 7 rear driving axle, the transmission connection of front propeller shaft 9 front driving axle.
The present invention is used using the torsional differential gear 13 as inter-axle differential for the first time, realizes shaft space difference speed, solve because
The inconsistent tire of antero posterior axis revolving speed eats tire problem, and difference in torque fast reaction can occur to antero posterior axis in the torsional differential gear 13,
The torque of antero posterior axis is redistributed, guarantees that engine is in relatively reasonable torque point always, has not only been able to achieve pre-post difference speed but also energy
It carries out two drive 4 wheel drivens and switches the adaptation, it can be achieved that different road conditions.
Advantage: (1) high efficiency drive, can be automatic to distribute antero posterior axis torque according to the size of tire adhesion force, make engine
Always it is in relatively reasonable torque point；(2) it turns to adaptively, has shaft space difference speed, can distribute antero posterior axis has revolving speed, solves
Turn to difficult problem；(3) two drives/4 wheel driven handoff technique, vehicle have two drives, 4 wheel driven mode, can be under certain speed according to road conditions
Free switching solves the problems, such as that good road conditions 4 wheel driven mode oil consumption is high；Therefore the time sharing commercial vehicle with differential limitation can
Meet the driving requirements of skidding, cross-country road conditions, it is handling good, and can be realized the efficient utilization of engine torque, there is energy conservation
The effect of consumption reduction.
Working principle is as follows:
Two drive shelves: manipulation shift mechanism, and the synchronizer 5 is engaged with the rear transmission driven gear 6, the engagement at this time
Set 11 is in an off state, drive path at this time are as follows: is driven quilt after the power input shaft 1 → synchronizer 5 → described
Moving gear 6 → the inter-axle shaft 7 → the rear driving axle.
4 wheel driven shelves: manipulation shift mechanism, the synchronizer 5 engages with the 4 wheel driven driving gear 4, the engaging sleeve 11 with
The driving front driven gear 10 engages, and transmission point two lines at this time are transmitted to the front driving axle and the rear driving respectively
Bridge realizes 4 wheel driven driving.
Route 1 are as follows: the power input shaft 1 → 4 wheel driven driving gear 4 → 4 wheel driven driven gear 12 → described
The preceding jackshaft of the torsional differential gear 13 → described 8 → driving front driving gear 2 → driving front driven gear 10 → described
