The structure of the truck drive shaft of prior art is generally adopt thin-walled Electric Welded Steel Pipe to be main body, and burn-on at two ends weld yoke and splined shaft, make it into as a whole.Truck drive shaft is arranged on automobile chassis, and the power that motor car engine exports is passed to automobile drive axle by it.
When automobile in the process of moving, the noise that the component be connected with transmission shaft send can be delivered in the cavity of transmission shaft tube by the weld yoke on transmission shaft and splined shaft, the vibrations of two bursts, front and back and noise are pooled in the cavity of transmission shaft tube, will resonance be formed and send larger noise, badly influence the life-span of transmission shaft, and noise pollution is caused to environment.
Especially when tortuous road traveling, often to change and drive direction, owing to frequently turning to, when splined shaft is in the positive and negative reverse steering of splined shaft among alternate torque stress always, drive the spline block be riveted on splined shaft to clash between steering yoke two ear and open shelves, steering torque is transferred to steering wheel by steering yoke, realizes wheel steering.In above-mentioned course of action, be riveted on the effect of the spline block on splined shaft by alternate torque, spline block bi-side and steering yoke two ear leave can produce to commutate between shelves and clash into, thus send abnormal sound, cause the worry of driver, affect traffic safety performance, and this abnormal sound noise also affects car comfort.
Model utility content
For the defect existed in prior art, the purpose of this utility model is to provide a kind of new automobile transmission shaft, can reach the object of damping and noise reduction, improves the life-span of transmission shaft.Particularly can avoid, because turning to the abnormal sound clashing into and produce, improve Security and the travelling comfort of automobile running.
For reaching above object, the technological scheme that the utility model is taked is: a kind of new automobile transmission shaft, comprises the universal-joint fork, steering yoke, splined shaft, central siphon and the weld yoke that are connected successively; Wherein, be pressed with an inner spline housing in steering yoke, an end of splined shaft press-fits in inner spline housing, and the end that splined shaft is positioned at this inner spline housing also presses and is connected with a spline block; Described central siphon is hollow structure, is filled with damping packing in it; Described spline block outer surface is coated with one deck beam.
Further improvement is: described central siphon offers a through hole, is welded with a plug in this through hole.
Further improvement is: described through hole is positioned at the joint of central siphon and weld yoke.
Further improvement is: the sidewall of described central siphon is provided with an equilibrium block.
Further improvement is: described damping packing is polyurethane.
Further improvement is: described beam is rubber pad.
Further improvement is: described rubber pad and the sulfuration of spline block or bonding connection.
Further improvement is: described steering yoke is connected with universal-joint fork by articulated cross shaft.
Further improvement is: described splined shaft is connected with shaft pipe welding.
Further improvement is: described central siphon is that aluminum alloy material is made.
The beneficial effects of the utility model are:
1, in the utility model, central siphon is hollow structure, is filled with damping packing (polyurethane) in it, and this damping packing can absorbing vibration and noise, therefore, it is possible to reach the object of damping and noise reduction, improves the life-span of transmission shaft.
2, the utility model structure is simple, compact, reasonable, it is on intrinsic basis, beam (rubber pad) has been added to spline block, because one decks many between spline block and steering yoke have the beam of vibration-absorbing function, therefore, be no longer rigid impact between spline block and steering yoke, thus eliminate the abnormal sound because rigid impact produces, improve Security and the travelling comfort of automobile running.
3, in the utility model, a through hole is offered at central siphon, a plug is welded with in this through hole, operator can utilize high pressure foaming machine to inject damping packing (polyurethane) in the central siphon of transmission shaft, plug beyond the Great Wall, when after the slaking at a certain temperature of damping packing, then plug is welded, easy to operate.
