The slip-limiting differential mechanism comprises a left sun gear and a right sun gear. The slip-limiting differential mechanism has the structural key points that the left sun gear is meshed with a left planetary gear; the right sun gear is meshed with a right planetary gear; and the left planetary gear is meshed with the right planetary gear, and two ends of the left planetary gear and the right planetary gear are respectively disposed on a rotating housing.
Description
Technical field
The utility model relates to the improvement of automobile differential structure.
Background technique
Existing automobile differential satisfies during design: " left half axle rotating speed+right axle shaft rotating speed=2 times rotational shell rotating speed ".When running into abominable road conditions, a side wheel fetal hair life is skidded or during unsettled phenomenon, can be caused the little wheel spin of adhesion (equaling 2 times of rotational shell rotating speeds, motor 100% torsion), and the big wheel transfixion (0 rotating speed, 0 torsion) of adhesion.Can lose whole power, vehicle can't move on.
At the shortcoming of existing open automobile differential, improved type automobile locking class differential mechanism has appearred on the market; This differential mechanism can only be installed on the non-steering shaft of automobile (rear axle).This be because: if said apparatus is installed on the steering axles (front axle), can cause left and right wheel to interfere when travelling, the lighter can not turn to, damage parts, and weight person can cause overturn accident.
Summary of the invention
The utility model is exactly at the problems referred to above, provides a kind of simple in structure, can be installed on the limited slip differential on the steering axles (front axle).
For reaching above-mentioned purpose of the present utility model, the utility model adopts following technological scheme, and the utility model comprises left sun gear and right sun gear, its structure outline: left sun gear is meshed with left lateral star gear; Right sun gear is meshed with right lateral star gear; Described left lateral star gear and right lateral star gear are meshed, and left lateral star gear and right planetary two ends all are arranged on the rotational shell.
As a kind of preferred version, described left sun gear and left lateral star gear, right sun gear and right planetary gear ratio are 3:1.
The beneficial effects of the utility model: 1, simple in structure: the utility model is arranged in the rotational shell by left sun gear, right sun gear, left lateral star gear and right lateral star gear and constitutes, and it is simple in structure, and the reliability height keeps in repair easy.
2, energy-saving and emission-reduction, safety coefficient height: use the torsion of motor car engine of the present utility model to tend to the big single wheel output of adhesion, wheel one side skids, when unsettled, motor can be passed to torsion the big side of adhesion, rather than pass to the little side of adhesion, sun gear of the present utility model and planetary gear ratio are 3:1, and according to the sun gear number of teeth and planetary pinion gear ratio as can be known: left and right torsion range of distribution of taking turns is distributed between 25%-75% automatically.The phenomenon that can avoid single wheel to skid timely or dally; Compare with other locking class differential mechanism, do not have hysteresis phenomenon; Thereby avoid many oil consumptions, reach the purpose of energy-saving and emission-reduction; In addition, the utility model is installed on the front axle of automobile, can also improve the passing capacity of front-drive car, shortens braking distance, has increased the automotive safety coefficient.
3, can be installed on the steering axles (front axle): because structural feature of the present utility model, the utility model not only can be installed on the non-steering shaft of automobile (rear axle), also can be installed on the steering axles (front axle), and be installed between steering shaft (front axle) and the non-steering shaft (rear axle) as interaxial differential, thereby, greatly improve cross country power.

Fig. 2 is a stereogram of the present utility model.
Fig. 3 is the stereogram of another angle of the utility model.
1 is that rotational shell, 2 is that right lateral star gear, 3 is that right sun gear, 4 is that left sun gear, 5 is left lateral star gear in the accompanying drawing.
Embodiment
The utility model comprises left sun gear 4 and right sun gear 3, and left sun gear 4 is meshed with left lateral star gear 5; Right sun gear 3 is meshed with right lateral star gear 2; Described left lateral star gear 5 and right lateral star gear 2 are meshed, and the two ends of left lateral star gear 5 and right lateral star gear 2 all are arranged on the rotational shell 1.
As a kind of preferred version, described left sun gear 4 and left lateral star gear 5, the gear ratio of right sun gear 3 and right lateral star gear 2 is 3:1.
The planetary gear set that described left lateral star gear 5 that is meshed and right lateral star gear 2 are constituted is set at least two groups.
When the utility model forthright travels, 1 rotation of transmission shaft driven rotary shell, rotational shell 1 drives left lateral star gear 5 and right lateral star gear 2 revolves round the sun around the axis of left sun gear 4 and right sun gear 3; Left lateral star gear 5 and the 2 no rotations of right lateral star gear, and drive left sun gear 4 and right sun gear 3 speed rotation together, the driving automobile left and right wheels is along straight ahead or back leg.
During turning, 1 rotation of transmission shaft driven rotary shell, rotational shell 1 drives left lateral star gear 5 and right lateral star gear 2 revolves round the sun around the axis of left sun gear 4 and right sun gear 3; Left side sun gear 4 makes its rotating speed different with right sun gear 3 because of turning, and at this moment, left lateral star gear 5 and right lateral star gear 2 are because of the reverse rotation that is meshed; This moment, left lateral star gear 5 and right lateral star gear 2 promptly revolved round the sun and rotation, and torsion is to transmit from left and right sides semiaxis-left sun gear 4, right sun gear 3-left lateral star gear 5, right lateral star gear 2 engagement places, thereby realized the differential of vehicle right and left wheel.
When abominable road conditions are travelled, 1 rotation of transmission shaft driven rotary shell, rotational shell 1 drives left lateral star gear 5 and right lateral star gear 2 revolves round the sun around the axis of left sun gear 4 and right sun gear 3; When single wheel adhesion descended or is unsettled, left sun gear 4 and right sun gear 3 there is no speed discrepancy, and left lateral star gear 5 and right lateral star gear 2 continue revolution synchronously; Torsion is left lateral star gear 5, right lateral star gear 2-left sun gear 4, the right sun gear 3-left and right sides semiaxis from rotational shell 1--engagement, unidirectional transmission, therefore, unsettled wheel can not dally, skid and lose whole power, vehicle can move on, and on-slip does not have hysteresis quality, energy-saving and emission-reduction fully.
