Abstract
The present invention is " double controllable differential mechanisms of pinion gear group ", and it controls gear (3) transfer gears (4) left half axle gears (5) right axle shafts gear (6) and shaft gear (7) to form by wandering star group (1) (2).It can be achieved to prevent a series of actions such as wheel-slip turn inside diameters by manipulating control gear (3).
Description
Technical field
The present invention relates to a kind of device of transmission of automobile chassis, the controllable differential of more particularly to a kind of double pinion gear groups
Device.
Technical background
Up to the present, all automobile differentials are all by one group of semiaxis driving vapour of pinion gear group connection left and right two
What Chinese herbaceous peony was entered, if run into muddy road surface skidding, the situation that single wheel skidding opposite side wheel does not turn, car often occurs
Just it can not advance.Even if installing differential lock additional, also the effect of certain speed differential lock competence exertion, the present invention are gone to when wheel
These shortcomings are overcome, locking skidding wheel makes vehicle derailing dangerous situation at once when a wheel skidding.
The content of the invention
The controllable differential mechanism of the present invention, there are two completely identical in structure pinion gear groups in parallel and by a umbrella shape tooth
Wheel controls its rotation direction, so as to reach expected results.
Brief description of the drawings
Shown in the drawings is " double controllable differential mechanisms of pinion gear group " of the present invention, and it is identified by dotted box
Pinion gear group (1) (2) control gear (3) transfer gears (4) left half axle gears (5) right axle shafts gear (6) and
Shaft gear (7) forms.
When vehicle is kept straight on, engine power passes to shaft gear (7), is seen in face of this figure, and travelling gear (7) is turned left
It is dynamic, drive transfer gear (4) and both sides bevel gear to turn downwards, power is transmitted to a left side by two pinion gear group (1) (2)
Right two axle shaft gear (5) (6) are rotated up.Now, because both sides tire is identical with the frictional force on road surface, gear (3) is controlled
Do not rotate, vehicle forward.
When vehicle is turned right, right side wheels radius of turn is small, and left side wheel radius of turn is big.Left side wheel rotating speed is more than
Right side wheels.Right side pinion gear group (2) turns downwards, and left side pinion gear group (1) turns upwards, and control gear (3) is turned left.Instead
It, it is as the same.
If installing torque motor additional on control gear (3), control gear (3) can be manipulated and rotated to the left or to the right, generation
Steering operation is carried out for hydraulic steering booster.Again during normally travel, controllable differential mechanism and open differential of the invention
Function is identical.
When running into muddy road surface, it may appear that the situation that single wheel skidding opposite side wheel does not turn, if left side is skidded
And right wheel does not turn, now left side pinion gear group (1) and right side pinion gear group (2), each rotate round about, control
Gear (3) is then quickly much higher than rotating speed during normal turn to anticlockwise, its rotating speed, and signal can be obtained by sensor,
Driving moment motor and control gear (3) are rotated to opposite direction, left side wheel is stopped operating, and power is all gone to right side,
Right side wheels are driven, make vehicle derailing predicament.
Claims (3)
1. a kind of double controllable differential mechanisms of pinion gear group, it controls gear (3) transfer gears by pinion gear group (1) (2)
(4) left half axle gears (5) right axle shafts gear (6) and shaft gear (7) composition.
" double controllable differential mechanisms of pinion gear group " 2. as claimed in claim 1, it is characterised in that：Pinion gear group (1)
It is in parallel by transfer gear (4) with pinion gear group (2).
" double controllable differential mechanisms of pinion gear group " 3. as claimed in claim 1, it is characterised in that：By control gear (3)
The rotation direction of pinion gear group (1) and (2) is restricted, to reach the purpose for turning and preventing wheel-slip.
