Description
Technical field
The utility model relates to the driving jackshaft of wheeled car, is the driving jackshaft with composite high-passage differential transmission mechanism supporting (as disclosed torque transfers such as patent No. ZL98100725.2, patent No. ZL 99208786.4, ZL01114361.4, the patent No.s 01250089.5).
Background technology
Main subtract device, an inter-wheel differential are arranged in the axle housing of existing driving jackshaft, an interaxle differential, torque input shaft fixedly driving gear drives interaxle differential, one semiaxis of interaxle differential is imported back axle with moment of torsion by output shaft, another semiaxis is fixed ring gear of a gear mesh, and this ring gear is fixed on the awl driving gear, and engagement awl ring gear drives inter-wheel differential, moment of torsion is assigned to the both sides jack shaft, drive the left and right wheel of jackshaft.This complex structure, volume that drives jackshaft is big, and the short transverse height takes up room, and is unfavorable for arranging.
Summary of the invention
For solve complex structure, volume that existing driving jackshaft exists big, take height space, be unfavorable for the problem of arranging, the utility model proposes a kind of driving jackshaft.
For this reason, the technical solution of the utility model is: drive jackshaft, comprise axle housing, the left jack shaft of band universal-joint, the right jack shaft of band universal-joint, the left jack shaft of band universal-joint, the right jack shaft symmetry of band universal-joint is installed in the axle housing, it is characterized in that: it also comprises two interaxle differentials, left power input shaft, right power input shaft, left back bridge output shaft, right back bridge output shaft, radially is provided with left moment of torsion input cavity, right moment of torsion input cavity side by side at the midway location of axle housing; Two interaxle differentials are installed in respectively in left moment of torsion input cavity, the right moment of torsion input cavity; The input end that is contained in the interaxle differential in the left moment of torsion input cavity is connected with left power input shaft, a mouth is connected with left back bridge output shaft, another mouth is by fixing being meshed by dynamic bevel gear on left drive bevel gear and the left transition axis, and left transition axis is connected with left power input shaft; The input end that is contained in the interaxle differential in the right moment of torsion input cavity is connected with right power input shaft, a mouth is connected with right back bridge output shaft, another mouth is by fixing being meshed by dynamic bevel gear on right drive bevel gear and the right transition axis, and right transition axis is connected with right power input shaft; The flank of tooth of left side drive bevel gear and the flank of tooth of right drive bevel gear are along the central axis positioned opposite of axle housing.
The utility model is owing to arrange left and right sides interaxle differential respectively at axle housing, and left and right wheels drives respectively, has cancelled inter-wheel differential, and differential transmission systems and axle housing are combined as a whole, and makes designs simplification, has particularly reduced height space, is beneficial to car load and arranges.
