Wheel is on a straight line and is engaged with each other, and another second gear is with another first gear is on a straight line and is engaged with each other；It is logical
Above-mentioned setting is crossed, bidentate wheel construction can be formed at the two ends of bent axle, so that can accomplish to put down during the both sides stress of bent axle
Force to bent axle, so as to torsion phenomenon and phenomenon of rupture efficiently against bent axle, so as to effectively extend whole joint
Service life.
On the basis of above-mentioned technical proposal, the present invention can also make following improvement：
As preferred scheme, outside the ends of above-mentioned inputting shaft, clutch shaft bearing shelves and are also symmetrically provided with
Two bearing guards, which connects bearing respectively.
Using above-mentioned preferred scheme, compared to existing cantilever support form, noise and vibration can be efficiently reduced
Phenomenon.
Used as preferred scheme, the length of above-mentioned clutch shaft bearing shelves is longer than the length of second bearing shelves.
Using above-mentioned preferred scheme, noise and oscillation phenomenon can be further reduced.
Used as preferred scheme, above-mentioned second bearing shelves connect driving means by bearing.
Using above-mentioned preferred scheme, can be formed into power driving effect.
Used as preferred scheme, above-mentioned driving means are motor.
Using above-mentioned preferred scheme, further can be formed into power driving effect.
As preferred scheme, outside the ends of above-mentioned bent axle, 3rd bearing shelves and the 4th are also symmetrically provided with
Bearing guard, which connects bearing respectively.
Using above-mentioned preferred scheme, can further balance crankshaft two ends stress.
