US Patent:

Filed:

Jan 2, 2002
Appl. No.:

10/038705
Inventors:

Barker J. Juhl - Saint Petersburg FL 33704
International Classification:

F16D 1104
US Classification:

192 6943
Abstract:

An adapter assembly mounted on a road vehicle between a driving axle and a road wheel allows a user to selective either a driving configuration, for use when the vehicle is to be driven or a free-wheeling configuration, for use when the vehicle is to be towed. Such an adapter may comprise a spindle, a hub, a spring-biased locking gear, a set of pushrods and a cam that can oscillate about the spindle. The locking gear has a splined periphery for engaging a splined internal portion of the hub and a splined axial throughhole for engaging a splined portion of the spindle. When the cam is turned in one direction the pushrods push the locking gear into the driving configuration in which the gear connects the hub to the spindle when the splined periphery engages the hub and the splined throughhole engages the spindle. When the cam is turned in the other direction, the bias spring pushes the locking gear outwards from the vehicle into the free-wheeling configuration in which the gear does not connect the hub and spindle.

Appl. No.:

6/125520
Inventors:

Barker J. Juhl - Springfield IL
International Classification:

B60B 2702
US Classification:

403 1
Abstract:

A device provides free-wheeling four-wheel towing of an automotive vehicle without damage to its (especially automatic) transmission. It is easily insertable co-axially between the power-driven wheel-mounting structure and the removed and replaced wheel. It comprises a base plate, a shaft on the base plate, a hub rotatable around the shaft, and a second wheel-mounting plate fixed to the hub by short lug-screws. The free-wheeling can be locked-out by substituting long lug-screws for half of the short ones. The long lug-screws enter threaded bores in posts fixed to the base plate to lock-out the free-wheeling, and they are slightly thinner then the short lug-screws to facilitate their placement.
