Embodiment
In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with accompanying drawing pair
The utility model is further detailed.
Referring to a kind of steering drive axle attachment structure shown in Fig. 1 to Fig. 4, provided for the utility model embodiment, including
Upper power transmission shaft 5 and lower drive shaft 1, upper power transmission shaft 5 are connected by universal joint with steering wheel, and lower drive shaft 1 is by universal joint with turning
It is connected to device.This programme realizes the connection of upper and lower power transmission shaft using a tray joint shaft 3, realizes the flexible connection of two connecting shafts.
Specifically, in this programme, the end of upper power transmission shaft 5 is circumscribed with first flange disk 51, along first flange disk 51
The opposed inside cutting in outer end forms one group of U-shaped stopper slot.
The end of lower drive shaft 1 is circumscribed with second flange disk, and second flange disk is provided with one group of mounting hole, and its cooperation is spacing
Bolt 7 and tray joint shaft 3 realize the connection of first flange disk 51 and second flange disk.
The middle part of wherein tray joint shaft 3 has centre bore, has via in the both sides of centre bore；Tray joint shaft 3 is towards the first method
The side of blue disk 51 is provided with the stop collar 31 for being used for accommodating first flange disk 51, by first flange in stop collar 31, it is ensured that
Stop collar 31 and the Movement consistency of first flange disk 51.For more preferably, first flange disk 51 is bar shaped knot in the present embodiment
Structure, to facilitate it to install and use.
The both ends of upper power transmission shaft 5 and lower drive shaft 1 are plugged in centre bore respectively, and centre bore plays two power transmission shafts of positioning
Effect, it is ensured that lower drive shaft 1 and upper power transmission shaft 5 are concentric.The bottom of caging bolt 7 sequentially passes through via, U-shaped stopper slot, installation
First flange disk 51 and second flange disk are pressed on tray joint shaft 3 behind hole；The face of cylinder of caging bolt 7 and U-shaped stopper slot it
Between there is gap, wherein, caging bolt 7 is two, and it compresses the U-lag that is acted on by bolt head on first flange disk 51
Outer realize.When relative torsion occurs for upper power transmission shaft 5 and lower drive shaft 1, tray joint shaft 3 will be driven to twist deformation,
To eliminate twisting vibration, due to having gap between the face of cylinder of caging bolt 7 and U-shaped stopper slot, it is ensured that the upper He of power transmission shaft 5
Lower drive shaft 1 can produce relative rotation, and avoid twisting vibration from being delivered to power transmission shaft 5, and then be delivered on steering wheel, influence to drive
The person's of sailing driving experience.
Tray joint shaft 3 is made up of elastomeric material, and vibration and distortion caused by vehicle travel process are delivered to lower rigidity and turn to biography
In moving axis 1, when axial vibration occurs for lower drive shaft 1, the first flange disk 51 by the end of lower drive shaft 1 is driven flexible
Elastic deformation occurs vertically for reel 3, eliminates axial vibration, in tray joint shaft 3 buffer part can be set to realize that buffer part can in addition
For groove or cavernous structure.
In addition, in this programme, a rigid limit can be also set to cover 4 outside caging bolt 7, rigid limit covers 4 pairs of tray joint shafts 3
Playing a protective role, when avoiding its rotation generation, caging bolt 7 is acted directly at U-shaped stopper slot, wherein, rigid limit set 4
It is pressed on second flange disk by the head of caging bolt 7, is had between the outer face of rigid limit set 4 and U-shaped stopper slot
Gap, rigid limit set play a part of protecting first flange disk U-shaped stopper slot.
Furthermore, it is understood that may also set up protection structure on the U-shaped stopper slot of first flange disk 51, used in this programme
Rubber sleeve 6 is further protected to first flange, wherein, the endoporus of rubber sleeve 6 is its spacing hole；Rubber sleeve 6 is T junction
Structure, including the limiting section that is plugged in U-shaped stopper slot of bottom and top are pressed on the compressed part of U stopper slots outer；Rigid limit
Set 4 passes along spacing hole and has gap between spacing hole.It should be noted that the thickness of rubber sleeve 6 and the depth of stop collar
It is equal, make it that its end face is concordant with stop collar after rubber sleeve is installed, it is ensured that it fixes reliable.
When needing to turn to, driver turn steering wheel, power transmission shaft 5 rotates in drives, the upper drive of power transmission shaft 5 tray joint shaft 3
Torsional deflection, upper power transmission shaft 5 and lower drive shaft 1 relatively rotate, and make the U-shaped on the end first flange disk 51 of power transmission shaft 5 spacing
Gap e between the lateral surface of rigid limit set 4 outside the spacing hole and caging bolt 7 of rubber sleeve 6 in hole disappears, upper transmission
Axle 5 and lower drive shaft 1 are rigidly connected by the face of cylinder on caging bolt 7 in rotation direction, and upper power transmission shaft 5 passes through spacing spiral shell
Bolt 7 drives lower drive shaft 1 to rotate, and steering moment caused by driver turn steering wheel is reliably passed into steering gear, realizes
Steering operation, after steering wheel returns just, under the elasticity of torsion power effect of tray joint shaft 3, rubber sleeve 6 on first flange disk 51
The gap e between rigid limit set 4 outside spacing hole and caging bolt 7 recovers.
So the flexible connection can either reliably transmit steering torque, while can also eliminate because garage crosses
Influenceed in journey by motive power, caused axial vibration, twisting vibration and noise in steering spindle.Due to structure letter
Single, manufacturing cost is relatively low, is well positioned to meet the shock attenuation needs of the steer drive of the products such as light passenger train, improves the operation of product
Comfortableness.
Some one exemplary embodiments of the present utility model are only described by way of explanation above, undoubtedly, for
One of ordinary skill in the art, can be with a variety of in the case of without departing from spirit and scope of the present utility model
Mode is modified to described embodiment.Therefore, above-mentioned accompanying drawing and description are inherently illustrative, should not be construed as
Limitation to the utility model claims protection domain.
