Include left shell, the described whole lateral surface of left shell has been provided with anti-guard, described anti-guard is by integrally having formed
Sawtooth portion and bending stage portion composition.
The measure taken for optimizing such scheme specifically includes：
In a kind of above-mentioned drive shaft assembly exterior protection structure, the left end of described left cage assembly is connected with input
Axle, on described input shaft, set is provided with protective cover part.
In a kind of above-mentioned drive shaft assembly exterior protection structure, described protection cover piece up and down directly with diameter greater than
The diameter of anti-guard.
In a kind of above-mentioned drive shaft assembly exterior protection structure, described left outside cage assembly and intermediate connecting shaft it
Between flexible adjustment assembly is set.
In a kind of above-mentioned drive shaft assembly exterior protection structure, described elasticity adjustment assembly includes floating rolling part
And spring part, described spring part is integrally enclosed within intermediate connecting shaft, described floating rolling part be arranged on spring part with middle
Between connecting shaft.
In a kind of above-mentioned drive shaft assembly exterior protection structure, the right-hand member of described elasticity adjustment assembly is provided with admittedly
Dead axle holds.
In a kind of above-mentioned drive shaft assembly exterior protection structure, the right side of described right ectosphere basket assembly is provided with admittedly
Determine connecting shaft, described fixed connection shaft is disposed with short spline and fixing nut from left to right.
Compared with prior art, the utility model has the advantage of utilizing anti-guard and the protection cover piece of indentation
Cooperate and other parts isolated, sawtooth portion again using the fixation of other parts it is ensured that stablizing of whole drive shaft assembly
Run, whole drive shaft assembly does not connect composition only with two external ball cages and forms simultaneously, will wherein using elasticity adjustment assembly
One external ball cage is connected so that adjusting floatability more preferably with intermediate connecting shaft, and whole automobile driving axle entirety adaptability is stronger, pressure
Contracting long by 756 ± 3 (stretching long 794), such operating angle is bigger, can adapt to the pavement state of complexity, and constant speed drive's effect
Good, no matter transmission direction during work, the whole power transmission of six steel balls, compared with weiss universal joint, bearing capacity is strong, and structure is tight
Gather, easy accessibility.
