Abstract
The utility model relates to the housing assy of a kind of syllogic rear driving axle, it is characterized in that: comprise axle housing (4), described axle housing (1) comprises the upper axle housing body (1) and lower axle housing body (2) that cooperatively interact and connect, the central siphon (6) that an one end is fixedly connected with it is equipped with at described axle housing (1) two ends, all be connected an inner bushing ring (10) between each central siphon (6) and axle housing (1), connects dish (8) in the transition that is all connected of the other end of each central siphon (6).Advantage of the present utility model: axle housing provided by the utility model is segmentation structure, the independent machinework of each parts, processing request is low, after axle case assy assembling, its load-carrying capacity is high, compact conformation, and the processing technology of axle housing is simplified, Fabricating machinery input is little, efficiency is high, reduces productive costs.
Description
Technical field
The utility model relates to a kind of auto parts and components, particularly a kind of syllogic rear driving axle housing assy.
Background technology
Drive axle is in the end of Power Train, its basic function increases the torque transmitted by transmission shaft or change-speed box, and power is reasonably distributed to left and right driving wheel, also bear the vertical power, longitudinal force and the transverse force that act between road surface, vehicle frame or vehicle body in addition.Drive axle is generally made up of main reduction gear, diff, wheel drive and driving axle housing etc.
Driving axle housing, when running car, bears the road surface reaction and moment that are transmitted by wheel, then passes to vehicle frame through suspension.Therefore, driving axle housing meet have the prerequisite of enough strength and stiffness under, also require its lighter weight, to facilitate dismounting and the adjustment of main reduction gear.Current adopted driving axle housing is integral axle housing, and this axle housing mainly exists following shortcoming:
A, often kind of axle housing body can only use a kind of bridge type, poor universality, can not meet the variety hardware and software platform demand of client, and quality are large.
B, shell welding size are long, must use triangular plate, and this makes axle housing junction easily occur the phenomenon of welding.
The pressing equipment of c, axle housing, mould and associated welds tool structure are complicated, time-to-market is long and cost is high, can not make quick response, and can not meet the day by day harsh cost requirement of client to the demand of client.
D, factory assist auxiliary facility requirement high, have high input.
Utility model content
The purpose of this utility model is the phenomenon that the quality in order to solve present stage integral axle housing is large, poor universality, easily appearance are welded, the shortcomings such as Fabricating machinery has high input, and expense is high, and a kind of syllogic rear driving axle housing assy proposed.
To achieve these goals, the utility model have employed following technical scheme:
The housing assy of a kind of syllogic rear driving axle, it is characterized in that: comprise axle housing, described axle housing comprises the upper axle housing body and lower axle housing body that cooperatively interact and connect, the central siphon that an one end is fixedly connected with it is equipped with at described axle housing two ends, all be connected an inner bushing ring between each central siphon and axle housing, connects dish in the transition that is all connected of the other end of each central siphon.
On the basis of technique scheme, following further technical scheme can be had:
A ring stiffener is fixedly connected with in the side of described axle housing.
Described axle housing eliminates the set square welded in the above in prior art, and the side welding ring stiffener of axle housing, alleviates the weight of axle housing, enhance the intensity of axle housing simultaneously, the step of the welding of simplification, saved labour cost.
Described central siphon can select size according to actual needs, the commonality of rear axle housing body is strengthened, simplifies the processing mold of integral axle housing simultaneously, reduce the expense of mould,
Because central siphon circularity is high, do not need machinework directly to connect dish welding with transition, simplify integral axle housing postwelding in the past, after first two ends being machined to the higher pipe of circularity, then connect the operation of coiling and being connected with transition, its cost of manufacture is low.
The utility model has the advantage of: axle housing provided by the utility model is segmentation structure, the independent machinework of each parts, processing request is low, after axle case assy assembling, its load-carrying capacity is high, compact conformation, and the processing technology of axle housing is simplified, Fabricating machinery input is little, efficiency is high, reduces productive costs.
Accompanying drawing explanation
Fig. 1 is basic structure schematic diagram of the present utility model;
Fig. 2 is the front elevation of Fig. 1;
Fig. 3 is the A portion enlarged drawing of Fig. 2.
Detailed description of the invention
In order to make the utility model clearly understand, describe in detail this device below in conjunction with accompanying drawing, specific embodiment described herein only in order to explain the utility model, and is not used in restriction the utility model.
As shown in Figure 1, Figure 2 and Figure 3, a kind of syllogic rear driving axle housing assy that the utility model provides, it is characterized in that: comprise axle housing 4, described axle housing 1 comprises the upper axle housing body 1 and lower axle housing body 2 that cooperatively interact and connect, to be connected oil cap 8 after at the rear side of described axle housing 4, weld the ring stiffener 3 that becomes closed hoop structure in the front side of shell body 4, described ring stiffener 3 pairs of axle housings 4 play actv. booster action.An obturating plug 11 of draining the oil also is welded in the side of described lower axle housing body 2.
The central siphon 6 that an one end is fixedly connected with it is equipped with at described axle housing 1 two ends, all be connected an inner bushing ring 10 between each central siphon 6 and axle housing 1, described inner bushing ring 10 plays good booster action, each described inner bushing ring 10 all welds with corresponding axle housing 1 and central siphon 6, the central siphon 6 of side welds rear leaf spring seat assembly 7, soldering oil pipe bracket 9 on another central siphon 6, the transition that is all connected in the outer end of each central siphon 6 connects dish 8.
As required, described axle housing 4 is connected with the central siphon 6 of different length, to adapt to the needs of various bridge type, axle housing 4 is short, and the mould of processing axle housing is little, makes axle housing weld seam short, axle case assy welding is easy to control, and axle case assy cleanliness level is improved greatly.
Claims (2)
1. syllogic rear driving axle housing assy, it is characterized in that: comprise axle housing (4), described axle housing (1) comprises the upper axle housing body (1) and lower axle housing body (2) that cooperatively interact and connect, the central siphon (6) that an one end is fixedly connected with it is equipped with at described axle housing (1) two ends, all be connected an inner bushing ring (10) between each central siphon (6) and axle housing (1), connects dish (8) in the transition that is all connected of the other end of each central siphon (6).
