Abstract

The invention discloses a torque-variable differential mechanism. The torque-variable differential mechanism is characterized by comprising an input shaft (1), an input shaft bearing (2), a gasket (3), a triple tooth (4), a planet wheel (5), a differential shell (6), a planet wheel lining (7), an oil blocking cover (8), a rear half shaft gear bearing (9), a rear half shaft gear (10), an output shaft bearing (11), an output shaft (12), a rear half shaft gear lining (13), a locking nut (14), a planet wheel shaft (15) and a triple tooth lining (16). The torque-variable differential mechanism has the differential function of a common differential mechanism and also has a torque-variable function. Torque is input from the input shaft, part of the torque is transmitted through the triple tooth, and the other part of the torque is transmitted to the output shaft through the rear half shaft gear. As the pitch circle of the rear half shaft gear is not equal to the pitch circle of the triple tooth, the differential mechanism has the torque-variable function.

Description

Differential mechanism is turned round in a kind of change
Technical field:
The present invention relates to differential art field, is that differential mechanism is turned round in a kind of change specifically.
Background technique:
When automobile adopts multiaxis ransaxle, generally adopt transfer case by power distribution to each ransaxle, arrangement is complicated.Although existing automobile three ransaxles adopt planetary gear structure, but transfer case transmission do not adopted, but its complex structure, amount of parts is more, and weight is large.
Summary of the invention:
The object of the invention is to overcome the deficiency of above-mentioned prior art, and provide a kind of change to turn round differential mechanism, mainly solve existing automobile and adopt the problems such as multiaxis ransaxle arrangement complex structure, amount of parts complicated and that three ransaxles adopt planetary gear structure to bring are many, weight is large.
Technological scheme of the present invention is: differential mechanism is turned round in a kind of change, its special way is, input shaft, bearing of input shaft, packing ring, three teeth, planet wheel, poor shell, planet wheel lining, oil blocking cover, rear differential gear bearing, rear differential gear, output shaft bearing, output shaft, rear differential gear lining, locking nut, planet wheel shaft, three tooth linings, consists of; Bearing of input shaft, packing ring, three teeth, planet wheel shaft are installed successively from top to bottom on input shaft, between input shaft and three teeth, are established three tooth linings; On planet wheel shaft, establish planet wheel, between the two, establish lining; Oil blocking cover is fitted on poor shell, and will differs from valve jacket on planet wheel and planet wheel shaft component, with locking nut, planet wheel shaft is locked and adjusting play; On output shaft, establish successively from bottom to up output shaft bearing, rear differential gear, output shaft and rear differential gear bottom connect as one, between rear differential gear top and output shaft, establish rear differential gear lining, differential gear bearing after rear differential gear peripheral hardware, rear differential gear is connected with planet wheel, and input shaft is corresponding with position of output axle.
A kind of change of the present invention is turned round differential mechanism and is compared with the prior art had outstanding substantive distinguishing features and remarkable progress, and 1, compact structure, amount of parts is few, lightweight; 2, can, according to automobile multiaxis ransaxle transport characteristics, design arbitrarily the velocity ratio of differential mechanism; 3, simple in structure, easy accessibility.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
Drawing explanation:
1 input shaft, 2 bearings of input shaft, 3 packing rings, 4 three teeth, 5 planet wheels, 6 poor shells, 7 planet wheel linings, 8 oil blocking covers, 9 rear differential gear bearings, 10 rear differential gears, 11 output shaft bearings, 12 output shafts, 13 rear differential gear linings, 14 locking nuts, 15 planet wheel shafts, 16 3 tooth linings.
Embodiment:
Below in conjunction with accompanying drawing, the present invention is further described; Illustrated embodiment is only for explaining the present invention, not for limiting the scope of the invention.
Embodiment 1, referring to Fig. 1, according to design, need to select suitable three teeth 4, rear differential gear 10 and planet wheel 5; Bearing of input shaft 2, packing ring 3, three tooth linings 16,34, planet wheel shaft 15 are arranged on input shaft 1, again planet wheel 5, lining 7 are arranged on planet wheel shaft 15 successively, oil blocking cover 8 is fitted on poor shell 6, and difference shell 6 is enclosed within on planet wheel 5 and planet wheel shaft 15 components, with locking nut 14, planet wheel shaft 15 is locked and adjusting plays; Output shaft bearing 11, rear differential gear 10 are installed successively from bottom to up on output shaft 12, output shaft 12 connects as one with rear differential gear 10 bottoms, between rear differential gear 10 tops and input shaft 1, establish rear differential gear lining 13, differential gear bearing 9 after the outer installation of rear differential gear 10, rear differential gear 10 is connected with planet wheel 5; Input shaft 1 is corresponding with output shaft 12 positions.
Differential mechanism is turned round in a kind of change of the present invention, has the differential function of open differential, also has to become to turn round function; By planet wheel and three teeth, rear differential gear, realize the differential function of open differential; By the pitch circle gear ratio of planet wheel and three teeth, realize becoming and turn round function, moment of torsion is inputted from input shaft, part moment of torsion transmits by three teeth, a part transfers torque to output shaft by rear differential gear in addition, because of rear differential gear pitch circle and three pitch circles unequal, therefore this differential mechanism has to become, turn round function.
