Diff described in the utility model is dual input structure, that is: to stretch out differential gear box external in one end of imput shaft, and be connected with the mouth of electrical motor, and the overriding clutch of the imput shaft other end is connected with the output shaft of fuel engines by its outer shroud.When electrical motor is worked, electrical motor drives imput shaft and the gear reduction running of diff, and then drives the back axle of car load to rotate.Now, the interior ring of overriding clutch rotates with imput shaft, and the outer shroud of overriding clutch does not rotate, and fuel engines is not worked.
When fuel engines starts to start and work, the outer shroud of overriding clutch rotates with fuel engines output shaft, when the rotating speed of outer shroud surmounts the rotating speed of interior ring, the inner and outer ring of overriding clutch engages, in it, ring starts to rotate with outer shroud, now close electrical motor, make the imput shaft of diff and gear reduction drive running by fuel engines, thereby drive the back axle of car load to rotate.Because electrical motor is closed, so the output shaft of electrical motor is in the servo-actuated state that dallies.
As can be seen here, the utility model can upper electricity be started by operator and fuel oil starting switch is controlled, make car load between automatically controlled driving and fuel oil drive smoothly, switch like a cork, car load is before charging at night or in climbing like this, can stop using electrical motor and adopt fuel engines, to increase the mileage and the hill climbing ability that travel.The utility model is not only applicable to, on motor-tricycle, be applicable on the self-propelled vehiclees such as four-wheeled yet.
The exterior ring cap of described overriding clutch (3) is loaded in universal-joint adapter sleeve (4).The outer shroud of overriding clutch is connected with the output shaft of fuel engines by universal-joint adapter sleeve, not only can guarantee the reliability of transmission, and effective wear prevention.
For simplified structure, convenient for assembly, described differential casing (1) is comprised of left shell (1a) and right shell body (1b), and left shell (1a) is fixed with right shell body (1b) phase make-up.
Described overriding clutch (3) is positioned at outside differential casing (1), and the shell of overriding clutch (3) is fixed on the outer wall of right shell body (1b) by well-distributed bolt on circumference.Overriding clutch is arranged in the outside of diff, and dismounting is all very convenient, is conducive to safeguard and change.
Described overriding clutch (3) is positioned at differential casing (1), and the shell of overriding clutch (3) is fixed on the inwall of right shell body (1b) by well-distributed bolt on circumference.Overriding clutch is arranged in diff, and compact conformation, volume are small and exquisite.
Beneficial effect: the utility model can make car load select direct motor drive or fuel engines to drive as required, thereby course continuation mileage and hill climbing ability have effectively been improved, there is the features such as design is ingenious, simple in structure, transformation is easy, improvement cost is low, on three-wheel vehicle or four-wheeled, be all suitable for.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, differential casing 1 is comprised of left shell 1a and right shell body 1b, left shell 1a and right shell body 1b phase make-up, and be bolted.In described differential casing 1, be provided with primary speed-down driving gear 5, this primary speed-down driving gear 5 is directly manufactured in imput shaft 2, and imput shaft 2 supports with left shell 1a and right shell body 1b respectively mutually by two of left and right bearing.The left end of described imput shaft 2 stretches out left outside left shell 1a, and is connected with the output shaft of electrical motor, and the right-hand member of imput shaft 2 stretches out to the right outside right shell body 1b, and is connected with the output shaft of fuel engines by overriding clutch 3.
As shown in Figure 1, overriding clutch 3 is positioned at outside differential casing 1, the shell of this overriding clutch 3 is fixed on the outer wall of right shell body 1b by well-distributed bolt on circumference, the inner ring sleeve of overriding clutch 3 is loaded on the end of imput shaft 2 right-hand members, connects between the two by key.The exterior ring cap of overriding clutch 3 is loaded in universal-joint adapter sleeve 4, and the outer shroud of overriding clutch 3 is connected with the output shaft of fuel engines by universal-joint adapter sleeve 4.
As shown in Figure 1, described primary speed-down driving gear 5 is meshed with primary speed-down driven gear 6, and primary speed-down driven gear 6 is directly manufactured on transmission shaft 7, and the end at these transmission shaft 7 two ends is supported on left shell 1a and right shell body 1b by bearing respectively.In the left side of described primary speed-down driven gear 6, be provided with double reduction driving gear 8, this double reduction driving gear 8 is directly manufactured on transmission shaft 7, and double reduction driving gear 8 is meshed with double reduction driven gear 9.Box of tricks 10 is housed in the internal chamber of described double reduction driven gear 9, this box of tricks 10 is connected with the back axle interface 11 of the left and right sides, the back axle interface 11 on the left side is positioned at left shell 1a, the back axle interface 11 on the right is positioned at right shell body 1b, and each back axle interface 11 connects with corresponding semiaxis.
