Abstract

The utility model discloses a kind of reinforced axle main speed reducer assembly, it comprises reducer shell, input shaft, drive bevel gear, driven wheel of differential, output shaft and differential mechanism, differential mechanism comprises differential casing, and the planet pin be located in differential casing, differential casing is fixedly connected with driven wheel of differential, the two ends of planet pin are fixed with a planetary pinion respectively, the one end portion that two semiaxis extend in reducer shell does not have differential gear by spline joint, differential gear and planetary pinion are connected with a joggle, the internal spline number of teeth of differential gear is 25-30 tooth.The internal spline number of teeth of differential gear is increased to 25-30 tooth by the utility model, makes semiaxis can transmit larger moment of torsion, and therefore when comparatively complex road condition or the larger occasion of load-carrying, semiaxis is also not easy fracture, longer service life.

Description

A kind of reinforced axle main speed reducer assembly
Technical field
The utility model relates to a kind of reinforced axle main speed reducer assembly.
Background technique
Axle main speed reducer assembly is the key components and parts assembly on heavy-duty car, serves as the function increasing and turn round of slowing down.Main gearbox assembly mainly comprises reducer shell, input shaft, difference device assembly and output shaft, difference device comprises difference device housing, planet pin, planetary pinion and differential gear, differential gear is connected with semiaxis by spline, the internal spline number of teeth of existing differential gear is about 17 teeth, when comparatively complex road condition or the larger occasion of load-carrying, semiaxis easily ruptures, thus reduction of service life.
Summary of the invention
In order to solve deficiency of the prior art, the purpose of this utility model is to provide one can bear larger load, the reinforced axle main speed reducer assembly of longer service life.
For achieving the above object, the utility model is by the following technical solutions:
A kind of reinforced axle main speed reducer assembly, comprise reducer shell, input shaft, drive bevel gear, driven wheel of differential, output shaft and and differential mechanism, described input shaft, drive bevel gear, driven wheel of differential and differential mechanism are located in reducer shell, described drive bevel gear is located at an end of input shaft, and is connected with a joggle with driven wheel of differential; Described output shaft comprises two semiaxis, and one end of two semiaxis extends in reducer shell respectively, and is connected with differential drive; Described differential mechanism comprises differential casing, and the planet pin be located in differential casing, described differential casing is fixedly connected with driven wheel of differential, the two ends of described planet pin are fixed with a planetary pinion respectively, the one end portion that described two semiaxis extend in reducer shell does not have differential gear by spline joint, differential gear and planetary pinion are connected with a joggle, and the internal spline number of teeth of described differential gear is 25-30 tooth.
The outside of described reducer shell is provided with stiffening rib.
The utility model adopts above technological scheme, and the internal spline number of teeth of differential gear is increased to 25-30 tooth, makes semiaxis can transmit larger moment of torsion, and therefore when comparatively complex road condition or the larger occasion of load-carrying, semiaxis is also not easy fracture, longer service life.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details:
Fig. 1 is the structural representation of a kind of reinforced axle main speed reducer assembly of the utility model.
Embodiment
As shown in Figure 1, the utility model comprise reducer shell 1, input shaft 2, drive bevel gear 3, driven wheel of differential 4, output shaft and and differential mechanism, described input shaft 2, drive bevel gear 3, driven wheel of differential 4 and differential mechanism are located in reducer shell 1, described drive bevel gear 3 is located at an end of input shaft 2, and is connected with a joggle with driven wheel of differential 4; One end that described output shaft comprises two semiaxis, 5, two semiaxis 5 extends in reducer shell 1 respectively, and is connected with differential drive; Described differential mechanism comprises differential casing 6, and the planet pin 7 be located in differential casing 6, described differential casing 6 is fixedly connected with driven wheel of differential 4, the two ends of described planet pin 7 are fixed with a planetary pinion 8 respectively, the one end portion that described two semiaxis 5 extend in reducer shell 1 does not have differential gear 9 by spline joint, differential gear 9 and planetary pinion 8 are connected with a joggle, and the internal spline number of teeth of described differential gear 9 is 25-30 tooth.
The outside of described reducer shell 1 is provided with stiffening rib 10.
The utility model adopts above technological scheme, and the internal spline number of teeth of differential gear 9 is increased to 25-30 tooth, makes semiaxis 5 can transmit larger moment of torsion, and therefore when comparatively complex road condition or the larger occasion of load-carrying, semiaxis 5 is also not easy fracture, longer service life.
