Abstract
The utility model provides a 4.5-ton-class front driving axle, aiming to improve strength thereof and reduce cost. The technical scheme includes that the 4.5-ton-class front driving axle comprises a driving axle casing, a main speed reducer and differential assembly and an inner and outer half shaft assembly, the driving axle casing is in an integral structure, the driving axle casing with the square section is made of steel plates of the thickness ranging from 12mm to 14mm, the main speed reducer and differential assembly is a DongFeng EQ 145 main speed reducer and differential assembly, and the inner and outer half shaft assembly consists of an outer half shaft, an inner half shaft, an outer half shaft flange, an inner half shaft flange, a driving ring and two cross shafts. Two cross shaft connecting arms are arranged on two sides of the driving ring, the two cross shafts are mounted on the cross shaft connecting arms on two sides of the driving ring respectively and connected with the outer half shaft flange and the inner half shaft flange respectively, the inner half shaft flange and the inner half shaft are in spline fit and are axially limited, and the outer half shaft flange and the outer half shaft are in spline fit.
Description
Technical field
The utility model relates to car drive front axle.
Background technology
Present drive front axle, by driving axle housing, main reduction gear and differential assembly, inner shaft, outer semiaxis, croisillon de joint homocinetique, wheel hub brake drum assembly, tie rod assembly, drag link are formed; What adopt is croisillon de joint homocinetique, because the locus restriction, the croisillon de joint homocinetique design-calculated is thiner; Insufficient strength; Because outer semiaxis is locked with outer semiaxis bead, the croisillon de joint homocinetique a little less than the fragile intensity relative thin causes the inefficacy of drive front axle transmission agency when turning to.
Summary of the invention
In order to improve the intensity of drive front axle, cost-cutting, 45 tonnes of drive front axle of the utility model proposition.
For this reason, the technical scheme of the utility model is: 45 tonnes of drive front axle comprise driving axle housing, main reduction gear and differential assembly, inside and outside semiaxis assembly; It is characterized in that: driving axle housing adopts one-piece construction, and the cross section of driving axle housing is square, and employing thickness is that the steel plate of 12-14mm is processed; Main reduction gear and differential assembly are east wind EQ145 main reduction gear and differential assembly; Inside and outside semiaxis assembly is made up of outer semiaxis, inner shaft, outer semiaxis bead, inner shaft bead, driving ring, two center crosss; The both sides of said driving ring all are provided with the center cross connecting arm; Two center crosss are installed in respectively in the center cross connecting arm of both sides, two center crosss also respectively with outer semiaxis bead, inner shaft flange connection; Inner shaft bead and inner shaft spline fitted and axial limiting, outer semiaxis bead cooperates with outer Formation of Axle Shaft Spline.
Beneficial effect: the utility model adopts east wind EQ145 main reduction gear and differential assembly, not only is easy to obtain, and has reduced cost; Inside and outside semiaxis assembly adopts the double cruciform shaft structure; Intensity has all obtained reinforcement; Outer semiaxis is not locked with outer semiaxis bead, has removed the axial constraint of outer semiaxis outer end, the outer semiaxis interior twitch of splined hole of semiaxis bead outside when turning to; Eliminate the internal action power between inside and outside semiaxis and the driving ring, prolonged service life.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is along A-A cutaway view (enlarged drawing that has only kept inside and outside semiaxis assembly) among Fig. 1.
The specific embodiment
Like Fig. 1, shown in 2; It is following to further describe the utility model: 45 tonnes of drive front axle; Form by driving axle housing 7, main reduction gear and differential assembly 5, inside and outside semiaxis assembly, steering swivel shell 2, steering swivel supporting base and stub assembly 3, wheel hub brake drum assembly 1, tie rod assembly 6, drag link 4; Driving axle housing 7 adopts one-piece construction, and the cross section of driving axle housing is square, and employing thickness is that the steel plate of 12-14mm is processed; Main reduction gear and differential assembly 5 are east wind EQ145 main reduction gear and differential assembly; Inside and outside semiaxis assembly is made up of outer semiaxis 8, inner shaft 13, outer semiaxis bead 9, inner shaft bead 12, driving ring 11, two center crosss 10; The both sides of said driving ring 11 all are provided with the center cross connecting arm; Two center crosss 10 are installed in respectively in the center cross connecting arm of both sides, and two center crosss also are connected with outer semiaxis bead 9, inner shaft bead 12 respectively; Inner shaft bead 12 and inner shaft 13 spline fitted and axial limiting, outer semiaxis bead 9 and outer semiaxis 8 spline fitted.
