Description
Technical field
The present invention relates to a kind of automobile axle shaft is and in particular to a kind of automobile axle shaft of wear resistant and noise reducing；Belong to the vehicles zero
Component technology field.
Background technology
Automobile axle shaft is the solid shafting transmitting power between differential mechanism and driving wheel, its inner and differential side gear
Connect, and outer end is then connected with the wheel hub of driving wheel, the moment of torsion transmitting from differential mechanism, through semiaxis, wheel hub etc., is ultimately transferred to
Wheel, is a strength member of transmitting torque in power train.From the point of view of the classification of semiaxis, semiaxis can be divided into semi-floating, Quan Fu
The two kinds of form applications of formula and three kinds of 3/4 floating, wherein semi-floating and full floating are relatively broad.Wherein, semifloating axle shaft removes transmission
Outside moment of torsion, still suffer from the moment of flexure that vertical force, side force and longitudinal force are acted on, be typically used in that quality is less, use condition
Preferably, the also little car of bearing load and miniature visitor, on goods automobile, have that structure is simple, quality is little, compact dimensions, cost
Cheap the advantages of；And fully floating axle is in addition to transmitting torque, other power and moment to be born by axle housing, are commonly applied to light-duty
And above various cargo vehicles, offroad vehicle and passenger vehicle, structure is more complicated, and manufacturing cost is also of a relatively high.
In traditional handicraft, half forging shaft is to be produced by the way of swage forging on pneumatic hammer mostly, and technique falls behind,
Forging precision is low, and poor product quality and percent defective are high, and semiaxis bears torsion, pressure, frictional force etc. in use, and
And be exposed to the part of automobile external and can stand a certain degree of impact from dust, water, gravel particle and silt etc., lead to
Semiaxis noise is very big, and is easily damaged under high load capacity working condition, thus affecting vehicle safety, stability and using the longevity
Life, easily causes security incident.
The utility model patent of Application No. 201521003427.3 discloses a kind of motorbus automobile axle shaft, using pendulum
Roll over new technology manufacture, on the cone that will roll, mould, to blank end face pressurized, makes a kind of processing side that blank progressively shapes
Method.Because rotary forging deformation is localized contact pressurized in sequence, its contact area and unit pressure are all smaller, with local deformation
Substitute the bulk deformation in conventional forging, uniformly, workpiece quality is high for deformation, and metal streamline is good, and dimensional accuracy is high, machining amount
Less, material-saving and the energy, production efficiency is high, and noise is little, and work situation is good.But, this automobile axle shaft can not solve reality
The noise that in operation, automobile axle shaft exists is big, wear no resistance, the lost of life the problems such as, in consideration of it, how being necessary research
The stability improving automobile axle shaft is to improving the security performance of automobile.
