Description
Technical field
The utility model relates to the fields of transmission shaft, and in particular to a kind of aluminium driving shaft.
Background technique
It being stretched at home with external band in secondary transmission shaft at present, internal spline and external splines are all made of steel part and are made,
Even if the flexible aluminium driving shaft of part band, external splines is also steelwork, and steelwork weight weight, rotary inertia is big, automobile
The energy consumption generated in driving process is high, is unfavorable for environmental protection.And existing flexible pair is cooperated using involute or rectangular spline, this
Often gap is big for fit system, is easy to produce vibration noise, is unfavorable for the NVH performance of vehicle；In addition existing flexible pair is dust-proof
Using sealing sleeve pipe structure, oil sealing directly cooperates in spline housing outer circle, and causing oil sealing with outer circle, there are sliding motions, if outside
There is silt on circle, will lead to oil sealing breakage, extraneous silt and dust easily enters flexible pair, causes flexible secondary grease dirty
Dye makes flexible secondary initial failure.
Utility model content
The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a kind of aluminium driving shaft.
The purpose of this utility model is completed by following technical solution: this aluminium driving shaft mainly includes
Flanged yoke A, universal joint A, weld yoke, central siphon, spline housing, slip shaft yoke, universal joint B, flanged yoke B, clip A, bellows, clip
B, splined shaft connects central siphon after universal-joint A after flanged yoke A, universal joint A, and central siphon rear end is spline housing, is passed through in spline housing
Spline pair is coupled hollow splined shaft, and spline shaft rear end connects slip shaft yoke, be sequentially connected after slip shaft yoke universal joint B and
Flanged yoke B, spline pair outside are equipped with ripple protection of pipe, and the bellows both ends are interference fit and bellows both ends pass through respectively
Clip A and clip B are fixed on spline housing and slip shaft yoke.
The spline pair of the splined shaft and spline inner room using cold extruding formation process be processed into high-precision stepped tooth come
Realize cooperation.
Friction welding (FW) welding fabrication is all made of between the weld yoke and central siphon and between spline housing and central siphon.The splined shaft and
Slip shaft yoke uses friction welding (FW) welding fabrication.
The weld yoke, central siphon, spline housing and slip shaft yoke use aluminum alloy materials.
The utility model has the following beneficial effects: in the flexible pair of the utility model, the spline housing of internal spline and external splines
Slip shaft yoke is all made of aluminum alloy materials, removes steelwork, wherein splined shaft is hollow, can mitigate weight, weight significantly
Mitigate 30-50% than common drive axis, it is energy-saving；Parameter in flexible pair uses the special trapezoidal toothing of high-precision, matches
It is small to close gap, improves the NVH performance of vehicle；The dustproof construction cover for using bellows simultaneously makes flexible pair completely in bellows
Inside dust cover, thoroughly solving the problems, such as that extraneous silt and dust enter in flexible pair leads to flexible secondary initial failure.
