Description
Technical field
The utility model belongs to car chassis drive axle technical field, more specifically to the design improvement of the double diagonal line diff of 4Wdvehicle.
Background technology
For eliminate between automobile driving wheel and the ground and the drive wheel between each drive axle of multiple-axle drive vehicle with respect to the slippage between the ground and the phenomenon of trackslipping, the pure rolling between assurance drive wheel and the ground, the drive axle of modern automobile all is equipped with diff.Existing automobile four-wheel drive driving system have adopt before and after differential and propons part-time case two kinds between bridge twin-differential and bridge.The former is when reinforcing, and because of there not being differential between bridge, the Ackermann steer angle resistance is very big, can not use for a long time.The latter has interaxle differential, and four-wheel all can freely drive.But, to take turns when skidding as any one, vehicle will stop.As using differential locking-device, very inconvenient again.Above-mentioned shortcoming has had a strong impact on the driveability of 4Wdvehicle.
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, and a kind of alternative multi-section diff of a dual-purpose diff of using instead is provided, and can realize differential between four-wheel simultaneously; Can make the diagonal line two-wheeled of automobile avoid locking simultaneously or skid, good cross-country driveability is arranged, brake steadily, the double diagonal line diff of 4Wdvehicle that also can smooth-ride on rough road surface.
Summary of the invention
In order to achieve the above object, the differential gear box that is connected by the main reduction gear driven gear, with the main reduction gear driven gear of the utility model, be installed in planetary wheel center cross in the differential gear box, be installed in planetary wheel on the planetary wheel center cross, formed with two axle side gears of planetary wheel ingear and with the semiaxis of axle side gear bonding.It is a kind of between centers double diagonal line diff, and its output semiaxis has identical four of hand of rotation.
Between centers double diagonal line diff can be made up of two open differentials, and its four semiaxis are respectively through with the bevel gear of its bonding, with this bevel gear engagement and be installed in driven bevel pinion outputting powers on four output semiaxis of the near front wheel, off hind wheel, left rear wheel, off front wheel respectively.This structure also is contained in propons, is rotated to distribute by back axle and realizes that diagonal line drives differential.
Can be following structure also: the planetary wheel that is installed on the planetary wheel center cross has 8, and each axle head of planetary wheel center cross is installed two.The planetary wheel of its inside through two axle side gears, semiaxis, be bonded in two on the semiaxis bevel gear, with the engagement of this bevel gear and be installed in driven bevel pinion outputting power on the output semiaxis of the near front wheel and off hind wheel.The planetary wheel of its outside through two transition bevel gears and bonding axle thereof, be bonded on two bonding axles another to the transition bevel gear, with another to transition bevel gear engagement and be installed in driven bevel pinion outputting power on the output semiaxis of left rear wheel and off front wheel.
This is actually a kind of central composite differential, is that the axle head at each center cross installs a planetary wheel again additional.
Task of the present utility model comes to this and finishes.
Advantage of the present utility model and good effect are: no matter be to keep straight on or during in negotiation of bends, can both play differential between four-wheel at four-wheel.Use a dual-purpose diff instead and substitute the multi-section diff, volume is little.Can make the diagonal line two-wheeled of automobile avoid locking simultaneously or skid.When having only adjacent two-wheeled to skid simultaneously, Che Caineng stops.Two cover drive systems are arranged.Good cross-country driveability is arranged, good restriction is arranged between four-wheel, brake steadily.Particularly also can smooth-ride on rough road surface
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the scheme drawing of another kind of structure.
Fig. 3 is a principle schematic of the present utility model.
Shown in Figure 1, the utility model is by main reducing gear driven gear 1, differential carrier 2, planetary gear Axle 3, planetary gear 4, axle shaft gear 5 and semiaxis 6 form. A kind of between centers double diagonal line differential mechanism, Output axle shaft has identical four of rotation direction. Formed by two open differentials. Semiaxis 6 is respectively through bevel gear 7, be installed in respectively driven bevel pinion 12 outputting powers on the output axle shaft 8～11 of four-wheel.
Shown in Figure 2, the planetary gear 4 and 13 of another kind of structure has 8. Planet pin 3 every Individual axle head is installed two. Its inside planetary gear 4 through two axle shaft gears 5, semiaxis 6, be bonded in Bevel gear 14 on two semiaxis 6, with this bevel gear 14 engagements and be installed in the near front wheel and off hind wheel Driven bevel pinion 17 outputting powers on the output axle shaft 15 and 16. The planetary gear 13 of its outside is through two Individual transition bevel gear 18 and bonding axle 19 thereof, be bonded on two bonding axles 19 another to the transition umbrella Gear 20, the driven bevel pinion 23 that is installed on the output axle shaft 21 and 22 of left rear wheel and off-front wheel are defeated Go out power.
Figure 3 shows that the track of four-wheel drive vehicle four-wheel when min. turning radius is made circular motion. By In arrive outside, four concentric circles are respectively the movement locus of interior front-wheel, inner rear wheel, outer front-wheel, outer trailing wheel. If r is the smallest circumference moving radius of interior front-wheel, a is rear tread, and b is front tread, and M interiorly takes turns two The wheel track is poor, and N is that foreign steamer two-wheeled track is poor, then has:
Z1+Z4＝2πr+2π(r+M+b)＝2π(2r+M+b)
Z2+Z3＝2π(r+M)+2π(r+a)＝2π(2r+M+a)
Z1, Z2, Z3, Z4 are respectively the motion of interior front-wheel, inner rear wheel, outer front-wheel, outer trailing wheel in the formula The track girth. Again because of a=b, M=N, that is wheel base equates, interiorly takes turns difference to equal foreign steamer poor, therefore Z1+Z4=Z2+Z3 is arranged. A kind of double diagonal line differential mechanism of following formula explanation design is feasible, reasonable .
