Description: |
| Abstract:
In detachable and interchangeable wheel systems it is a known expedient to demount ably connect a wheel on its axle by multiple small screw bolts which pass through the boss of the wheel and the flange of an axle sleeve serving as a permanent hub on the one hand or as a differential sleeve on the other. An object of the present invention is to so connect a wheel for drive of rotation from the corresponding axle or from the corresponding sleeve of the compensating gear by a cross pin drive, the axes of whose members run parallel with the wheel axis, and with wedge action reacting on both parts to be joined that a few large bolts will serve, no more than two working well, also that an effective countering of that tendency to distort and unfigure the pins and the walls of their co-acting holes or passages to set up lost motion with consequent striking and hammering action shall be made possible. And simultaneously with doing this, better facilities are given for removing and replacing a wheel, these facilities inter alia allowing any wheel according to the system of the present invention to be, interchanged with any other wheel according to the same system provided only that the wheels are true to the same standard.
Claim:
In apparatus of the class described, in combination, a hub element provided with an outwardly extending member, a wheel provided with a member adjacent said first member, substantially registering openings in said members each of which in each member is shaped with substantially the same taper, tapering connecting members passing through said registering openings and haying substantially the same taper with each of the same, and means adapted to tighten said connecting members. |
