Abstract
The utility model discloses an axle main reducing gear casing and an axle main reducing gear assembly. Two holes which are used for mounting a differential mechanism connected with a driven gear and arranged on the axle main reducing gear casing are respectively a through hole with threads at the outer end and a step through hole, and one side, which is provided with the step through hole, of the casing is a side exerted with larger axial force transmitted by the driven gear. The axle main reducing gear assembly comprises a driving gear, the driven gear, the axle main reducing gear casing and the differential mechanism connected with the driven gear. The axle main reducing gear casing and the axle main reducing gear assembly greatly reduce fault probability and increase integral reliability of an automobile. Bearing capability of the axle main reducing gear casing to the axial force transmitted by the driven gear is increased, and the driven gear is not easy to move after being adjusted. Further, costs of products are reduced.
Description
Technical field
The utility model relates to a kind of auto parts and components, particularly a kind of vehicle bridge bevel housing and vehicle bridge main gearbox assembly.
Background technique
The vehicle bridge main gearbox assembly is the key components and parts assembly on the heavy-duty car, and it mainly acts on is that high speed drop with motor output gets off, to increase the automobile driving force.As the bevel housing of the strength member on the main reducing gear, play the effect of each part on the fixed support main reducing gear, it must have certain intensity and very high precision.The adjustment nut that is positioned at the main reducing gear two ends plays a part to adjust and fixing differential mechanism band driven wheel assembly.Because of driven gear is stressed bigger, and it is higher to adjust required precision, all requires high especially so the precision and the intensity of nut, particularly internal and external threads are adjusted in both sides.Be the Yi Fadian that the heavy-duty car vehicle bridge breaks down herein.Break down and will cause main reducing gear to lose efficacy in this position, automobile can't cruising.
Summary of the invention
Problem to be solved in the utility model is: a kind of big vehicle bridge bevel housing of ability that bears the axial force of driven gear transmission is provided, and a kind of vehicle bridge main gearbox assembly that adopts aforementioned vehicle bridge bevel housing is provided, make the vehicle bridge main gearbox assembly be difficult for breaking down.
For addressing the above problem, two holes that are used to install the differential mechanism that is connected with driven gear on the utility model vehicle bridge bevel housing are respectively screwed through hole in outer end and ladder hole, and a side at ladder hole place is the big side of axial force that transmitted by driven gear on the housing.
The utility model vehicle bridge main gearbox assembly comprises driving gear, driven gear, vehicle bridge bevel housing and the differential mechanism that is connected with driven gear, described vehicle bridge bevel housing is aforesaid vehicle bridge bevel housing, one end of differential mechanism is arranged in the screwed through hole in outer end of vehicle bridge bevel housing by bearing, be provided with the adjustment nut that is against on the bearing in the outer end of the screwed through hole in outer end, the other end of differential mechanism is arranged on by bearing in the macropore of ladder hole of vehicle bridge bevel housing, bearing in the ladder hole directly is against on the retaining platform of ladder hole, perhaps is provided with the adjustment pad between the retaining platform of bearing in the ladder hole and ladder hole.
The beneficial effects of the utility model: the retaining platform that the utility model will be changed on the housing by the bigger end adjustment nut of axial force supports differential mechanism band driven gear, greatly reduces fault probability of happening herein, has improved the vehicle complete vehicle reliability.Improved the ability to bear of vehicle bridge bevel housing to the axial force of driven gear transmission, and adjusted by the quantity of adjusting pad when regulating the driven gear position, after adjusting, the position of driven gear is difficult for the generation play.The utility model has also reduced product cost, has saved one and has adjusted nut, and be used to install brake pad and hexagon head bolt and the spring washer of adjusting nut.
Description of drawings
Fig. 1 and Fig. 2 are the structural representations of two kinds of specific embodiments of the utility model vehicle bridge main gearbox assembly.
Among the figure: 1, driving gear, 2, the vehicle bridge bevel housing, 3, adjust nut, 4, differential mechanism, 5, bearing, 6, driven gear, 7, bearing, 8, the retaining platform, 9, adjust pad.
Embodiment
A kind of vehicle bridge main gearbox assembly as shown in Figure 1, it comprises driving gear 1, vehicle bridge bevel housing 2, differential mechanism 4 and driven gear 6.
Driving gear 1 and driven gear 6 are meshed, driven gear 6 is by on the housing that is bolted to differential mechanism 4, two holes that are used to install differential mechanism 4 on the vehicle bridge bevel housing 2 are screwed through hole in outer end and ladder hole, and a side at ladder hole place is the big side of axial force that transmitted by driven gear on the vehicle bridge bevel housing 2.One end of differential mechanism is arranged in the screwed through hole in outer end of vehicle bridge bevel housing 2 by bearing 5, be provided with the adjustment nut 3 that is against on the bearing 5 in the outer end of the screwed through hole in outer end, one end of differential mechanism 4 is arranged on by bearing 7 in the macropore of ladder hole of vehicle bridge bevel housing 2, be provided with between the retaining platform 8 of bearing 7 and ladder hole and adjust pad 9, retaining platform 8 is the step between the two hole sections in the ladder hole.
The Placement of the structure of the housing of vehicle bridge main gearbox assembly shown in Figure 2 and differential mechanism 4 and housing and vehicle bridge main gearbox assembly shown in Figure 1 identical.
The stressed both direction that is decomposed into of driven gear 6, one is the rotational power around its gyration center, another is along the axial axial force of gyration center.On existing vehicle bridge main gearbox assembly, this axial force is finally born by the adjustment nut of a side, so this side adjustment nut is stressed bigger, fragile.And this axial force of the present utility model is finally born by retaining platform 8, has increased casing rigidity greatly, and adjusts pad 9 by increase and decrease, satisfies and adjusts requirement, and is more reliable, easily operation.
