The auxiliary axostylus axostyle 73 is ordered about in the conversion of gear train 723 and the equipment gear 74 is rotated, and is made by this
The torsion of the lifting of train of reduction gears 723 can be conducted to the linked gear 53, and is further provided for
The second output axostylus axostyle 51 and the first output auxiliary torsion of axostylus axostyle 41.
That is, respectively towards different directions extend this first output axostylus axostyle 41 and this second
Output axostylus axostyle 51 be can be subject to the driving of the input axostylus axostyle 31 and while rotate, and can be same
When receive the auxiliary power of the auxiliary power unit 7 and operate.
And the second construction section 411 and the second output axostylus axostyle due to the first output axostylus axostyle 41
One of them of 51 the 3rd construction section 511 be for installing and interlock direction main frame 92,
Therefore the vehicle (see Fig. 2) of front overhang car type long or the vehicle of short front overhang car type are either applied to
(see Fig. 3), even if direction column 91 is differed with the relative position of direction main frame 92,
Through using the present invention, remain able to optionally and by direction main frame 92 be installed on this first
Export the second construction section 411 of axostylus axostyle 41 and the 3rd construction section of the second output axostylus axostyle 51
One of them of 511, and can smoothly interlock direction main frame 92 and operate, thus be not required in response to
Different car type and change element and corresponding connecting element, and can be suitably used for different cars
, it is possible to significantly simplification assembles the flow of vehicle, and Unified Form single element
Also the cost on making can be reduced.
In sum, drive this that extend in different directions first defeated by the input axostylus axostyle 31
The design that output shaft lever 41 and the second output axostylus axostyle 51 are rotated simultaneously, and can be respectively applied to
Different car types, and the effect that simplification assembles flow and reduces cost is reached, so can reach really
Into the purpose of the present invention.
