Description
Technical field
The utility model belongs to automobile component assembly design field, relates to heavy motor vehicle and drives steeraxle axle case assy.
Background technology
Driving steeraxle is steeraxle and drive axle, and the axle case assy being made up of with steering swivel bearing axle housing is connected by steering yoke bolt with steering swivel, reaches and turns to object.Beam front axle housing assy plays a part supporting automobile load, and load is passed to wheel hub and pass to again wheel, acting on the tractive force, braking force, side force and the vertical force that drive on wheel is also to pass on suspension and vehicle frame or compartment through axle case assy, and therefore axle case assy is load member and force transmission element.So drive the type of attachment of steeraxle axle case assy to become the key of axle case assy strength weak.
Existing driving front steering axle axle case assy is to be linked together by carbon dioxide argon arc welding by steering swivel bearing 1-1 and axle housing 1-2, as shown in Figure 1.
This welding scheme has welding performance requirement because of part, and material carbon content is unsuitable too high, makes steering swivel bearing be subject to materials limitations, and the performances such as yield strength, hardness are not high, cannot meet the demand of bad working environments; Because of welding rear steering joint, bearing 1-1 becomes one with axle housing 1-2, if steering swivel bearing 1-1 or axle housing 1-2 are when the inefficacies such as plastic deformation occur, both all can not replace separately, non-interchangeability, and assembly reject rate is high; This welding scheme need carry out welding sequence, and this operation is prone to lack of root fusion, weld seam incomplete tusion, weld seam and heat affected zone defects i.e.cracks, easily occurs off gauge, and cost is high.
Utility model content
The technical matters that the utility model solves is to provide a kind of steeraxle axle case assy that drives.Steering swivel bearing and the axle housing of this axle case assy link together by locating dowel pin and assembling bolt, make part material not limited by welding performance, steering swivel bearing and axle housing still can be reprocessed separately or change after assembling, there is interchangeability, reduce costs, reduce special process in each operation and the advantage such as specious.
The technical solution of the utility model is that a kind of steeraxle axle case assy that drives, is made up of steering swivel bearing, locating dowel pin, axle housing, O RunddichtringO, bolt; The bolt connecting end surface of steering swivel bearing is collar plate shape, 1 dowel hole and N tapped through hole circumference uniform distribution on connecting end surface, the inner chamber of steering swivel bearing is stepped hole, the large diameter hole diameter of stepped hole is identical with O RunddichtringO external diameter, and the small diameter bore slightly larger in diameter of stepped hole is in the front side shaft diameter of axle housing; Locating dowel pin is for descending vertically milling flat; Locating dowel pin is through the dowel hole of axle housing and steering swivel bearing; The bolt connecting end surface of axle housing is collar plate shape, 1 dowel hole and N through hole circumference uniform distribution on connecting end surface, and an axle is stretched out in the connecting end surface front side of axle housing; N bolt passes N tapped bore of axle housing and steering swivel bearing.
Tapped bore quantity N is 13.
Technique effect of the present utility model is: in axle case assy, part material is unrestricted, can carry out material adjustment according to operating mode, easy to assembly, without the special process operation such as welding, significantly shortens whole bridge time of setting up.Axle case assy has ability to dismantle and interchangeability, reduces the assembly causing because of assembly part part failure and scraps, cost-saving.In this axle case assy, steering swivel bearing coordinates with the hole axle seam of axle housing and locating dowel pin all can effectively be resisted vertical loads, and bolt can effectively be resisted moment of torsion, meets operating needs completely by analytical calculation axle case assy.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of steeraxle axle case assy that drives of the present utility model, for the one formula axle case assy that is connected, is made up of steering swivel bearing 1, locating dowel pin 2, axle housing 3, O RunddichtringO 4, bolt 5, as Fig. 2, is the part broken away view of assembly in unassembled state.
1, the bolt connecting end surface of steering swivel bearing 1 is designed to collar plate shape, 1 dowel hole and 13 tapped through hole circumference uniform distributions on connecting end surface.Inner chamber is designed to stepped hole, coordinate as the space of mounting O-shaped seal ring 4 and with axle housing 3 hole shaft clearances, be for mounting O-shaped seal ring 4 on step, the large diameter hole diameter of stepped hole is identical with O RunddichtringO external diameter, the front side shaft seam location of the small diameter bore of stepped hole and axle housing, the small diameter bore slightly larger in diameter of stepped hole is in the front side shaft diameter of axle housing 3, as Fig. 3.O RunddichtringO prevents leakage of oil.
2, locating dowel pin 2 is upper and lower milling flat structure, prevents location, as Fig. 4.Locating dowel pin 2 is through the dowel hole of axle housing and steering swivel bearing 1.
3, in axle housing 3, bolt connecting end surface is collar plate shape, 1 dowel hole and 13 through hole circumference uniform distributions on connecting end surface.The stepped hole free-running fit of axle and the steering swivel bearing 1 of certain length is stretched out in connecting end surface front side, as Fig. 5.
4.O RunddichtringO 4 is selected (GB/T3452.1-165X5.3-G-S) from GB;
5. bolt 5 is selected (GB/T5785-M16X1.5X50-10.9-L) from GB.Bolt 5 is through the tapped bore of axle housing and steering swivel bearing 1.
Assembly technology:
1. parts are without burr, corrosion and damage and clean.
2., while assembling, axle housing 3 is put into assembly support, then the O RunddichtringO 4 that scribbles lithium base grease is enclosed within respectively on the axle matching with steering swivel bearing 1 on axle housing 3.
3. locating dowel pin 2 is respectively charged in the knock hole on steering swivel bearing 1, notices that the sub-plane of trial sale keeps level in the time of assembling.
4. steering swivel bearing 1 is installed to respectively to axle housing 3 two ends, finally use bolt 5 by fastening to axle housing and steering swivel bearing 1, Tightening moment is 240-260N.m, as shown in Figure 6;
Structure of the present utility model is carried out to strength check:
Application Adams/View builds multi-body Dynamics Model, checks bolt 5 stressing conditions.2.5 times of acceleration/accels when the limiting condition of axle case assy bearing load is static state, it can be 161890N in the hope of axle case assy one end suffered maximum shear stress of all bolts 5 that application Adams model emulation calculates.Bolt model M16x1.5, operative norm GB/T5786-2000.According to result of calculation, the intensity of 13 bolts meets operating needs.
Due to the complicated structure of axle housing 3 and turning support 1, adopt the method for finite element to carry out strength check.The specified axle load of axle case assy is 13 tons, and limiting condition is 2.5 normal accelerations, the monolateral lock torque that respectively adds 34350N.m of steering swivel bearing 1.
Result of calculation: under damped condition, non-hole site maximum stress 165MPa on axle housing 3, hole site maximum stress 268MPa (false stress) is all less than the yield limit 380MPa of axle case assy material; Steering swivel bearing 1 maximum stress 203MPa, is less than the yield limit 630Mpa of material.
This utility model meets the operating needs under limiting condition completely.
