Embodiment
Detailed introduction is done to the present invention below in conjunction with accompanying drawing：As shown in accompanying drawing 3,4, the present invention includes slip yoke 1, a left side
Universal joint 2, left weld yoke 3, right weld yoke 5, right universal joint 6, flanged yoke 7, one end and the slip yoke 1 of described left universal joint 2
It is connected, the other end of left universal joint 2 is connected with left weld yoke 3, one end of described right universal joint 6 is connected with flanged yoke 7
Connect, the other end of right universal joint 6 is connected with right weld yoke 5；Central siphon is fixed between the left weld yoke 3 and right weld yoke 5
4, the central siphon 4 is molded as one with left weld yoke 3, right weld yoke 5 by friction welding；The described end of slip yoke 1 and gearbox
Connection, the end of flanged yoke 7 is connected with back axle.
1st, it is simple in construction lightweight：Left weld yoke 3, right weld yoke 5 and central siphon 4 on the power transmission shaft use 6061-T6
Material, density is 2.7x10-6kg/mm3, is 1/3rd or so of steel density (7.8x10-6kg/mm3), in equal volume
Under, weight is 30% of steel part or so.Left weld yoke 3, right weld yoke 5 use aluminium bar forging forming, the solid solution at a temperature of 529 DEG C
Processing, carries out Ageing Treatment at a temperature of 177 DEG C afterwards, finally by machining earhole, jump ring and cylindrical.Central siphon 4 is used
The tubing of cold drawn forming.Left weld yoke 3, right weld yoke 5 are molded as one with central siphon 4 by friction welding.
2nd, intermediate support (middle auxiliary connection 8 and front axle tube 9, rear axle tube 10) structure as shown in Figure 1 is eliminated, is kept away
Exempt from, because intermediate support ageing of rubber softens, to increase the power transmission shaft amplitude of oscillation, the Vehicular vibration noise caused by.
Using two material frictional heats, Continuous Drive Friction Welding (inertia) is by weldering interface phase in the presence of friction pressure
Mutually contact, is rubbed by relative motion (general one quiet one moves), mechanical energy is changed into heat energy, thermogenetic using rubbing
High temperature thermoplasticity and friction pressure remove the oxide at interface, after the abrasion by one section of setting time or setting length, reach
Certain interface temperature and thermograde, brake and apply bigger upsetting force and kept for a period of time, in atom at once
Between gravitation be more than repulsion in the presence of carry out soldering, and the reliable welding being firmly combined with is formed by atoms permeating and recrystallization
Joint (core mechanism solves the query of ordinary person), welding manner belongs to Pressure Welding classification.
