Dynamic bridge.Transmission shaft structure layout is affected bigger by vehicle wheel base.Because having critical speed to retrain when power transmission shaft rotates, to transmission axial length
Degree requires, and also causes power transmission shaft dynamic balance performance very poor because the long flexibility of central siphon is excessive simultaneously, so, the biography being typically designed
Moving axis length is less than 1.5 meters.When automotive transmission output bead and drive axle input bead between length longer time (pass
Moving axis length is longer), need power transmission shaft to be designed to the structure that multisection type is arranged, to reach to meet critical speed and dynamic balance
The requirement of energy.General leading portion power transmission shaft is designed to the structure of band support and is connected with frame cross.If length is the longest, then need multiple
Support to be connected with vehicle frame and meet performance requirement.Back segment power transmission shaft is extension type, adapts to relative motion between suspension and vehicle frame.With
Output flange and the drive axle input flange of leading portion power transmission shaft are directly connected to.Typical 2 segmentation transmission shaft structures as shown in Figure 1,
Leading portion power transmission shaft is connected with variator output flange york by slip shaft yoke assembly and left cross axle, and back segment power transmission shaft is by welding
Fork and right cross axle are connected with drive axle input flange york.Stagewise power transmission shaft is arranged and be there is problems of because of propeller shaft length mistake
Long increasing supports attachment structure, increases the overall weight of drive shaft system, and the yielding rubber gasket ring in intermediate supports, makes simultaneously
Long period after, easy aging generation constringency cleft, cause the power transmission shaft amplitude of oscillation to strengthen, vehicle easily produces vibration noise；
The parts of bearings of intermediate supports also often results in inefficacy because of sealing dysplasia.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of major diameter transmission simplifying vehicle transmission shaft system arrangement
Axle construction.
In order to solve above-mentioned technical problem, the major diameter power transmission shaft knot of simplification vehicle transmission shaft system arrangement of the present utility model
Structure includes left cross axle, slip shaft yoke, splined sleeve, central siphon, weld yoke, right cross axle, it is characterised in that also include that transition is even
Acting flange；The external diameter of described central siphon is 150～300mm, a length of 2～3m；The right-hand member flared part of splined sleeve and central siphon
Left end is fixing to be connected；The right-hand member of central siphon left end with weld yoke blue by transition interfacing is fixed and is connected.
As preferably, the external diameter of described central siphon is 215mm, and wall thickness is 3mm, and the tolerance of the external diameter of central siphon and wall thickness is
±0.10mm。
As preferably, the two ends of described central siphon are with reducing；The right-hand member enlarging of splined sleeve is solid with the left end reducing of central siphon
Fixed connection；The right-hand member reducing of central siphon is fixing with transition interfacing orchid to be connected.
As preferably, left end reducing and the right-hand member reducing external diameter of described central siphon are 180mm, left end reducing and right-hand member reducing
Length L is 150～200mm, and angle A is 20～40 degree.
Described transition interfacing orchid is connected by the seam of its left end with the right-hand member reducing of central siphon and is welded and fixed.
This utility model is directed to a kind of major diameter transmission shaft structure simplifying vehicle transmission shaft system arrangement, and this structure is adopted
Improve critical speed of drive shaft, and then the license design length of increase power transmission shaft with increasing cardan-shaft tube diameter, cancel
The intermediate supports of stagewise power transmission shaft and attachment structure, arrange the layout becoming power transmission shaft, fall by stagewise power transmission shaft
Low weight and cost, it is to avoid due to problems such as the Vehicular vibration noises that intermediate supports causes, also simplify general assembly simultaneously.Its
The symmetrical expression reducing of central siphon two ends, decreases size for connection, central siphon external diameter and wall thickness tolerance and controls accurately, when meeting length increase
Flexibility is on dynamically balanced impact.This utility model has simple in construction, lightweight, and number of parts is few, low cost, assembling aspect
Etc. feature.
