Abstract
An apparatus and method for attaching a wheel to an axle. The apparatus comprises a wheel with a hub for insertion into an indentation in the end of the axle and a non-cylindrically-symmetrical stud attached to the axle that is concentric with the axis of rotation of the wheel and axle, attaching the wheel to the axle.
Claims5
A wheel and axle system, the system comprising:
- a. an axle having a rotational axis and an indentation at a wheel-coupling end for a wheel hub;
- b. a lug stud, extending from the wheel-coupling end of the axle, concentric with and parallel to the rotational axis of the axle, the lug stud not cylindrically symmetrical about the rotational axis of the axle;
- c. a wheel having a rotational axis through a center and a clearance hole to admit the lug stud, the clearance hole parallel to and concentric with the rotational axis of the wheel;
- d. a wheel hub, the wheel hub connected to the wheel and disposed within the indentation of the axle;
- and
- e. a fastener for attaching the wheel to the lug stud.
A method for attaching a wheel to an axle, the wheel having a rotational axis and a hub centered about the rotational axis and the axle having a rotational axis, the method comprising:
- a. aligning the rotational axis of the wheel with the rotational axis of the axle;
- b. inserting the wheel hub into an indentation in an end of the axle;
- and
- c. fastening the wheel to the axle at a point on the rotational axis of the wheel by inserting a lug stud through a clearance hole in the wheel and securing the lug stud with a fastener, the lug stud attached to the axle and not cylindrically symmetrical about the rotational axis of the axle.
A wheel, the wheel characterized by a rotational axis and a plane of rotation, the wheel comprising:
- a. a non-cylindrically-symmetrical clearance hole parallel to and concentric with the rotational axis of the wheel for admission of a lug stud;
- and
- a. a hub extending about the rotational axis outside the plane of rotation for insertion into an indentation in a wheel-coupling end of an axle.
An axle, the axle characterized by a rotational axis, the axle comprising:
- a. an indentation at a wheel-coupling end for a wheel hub;
- and
- b. a lug stud extending from the wheel-coupling end of the axle for securing a wheel, the lug stud parallel to and concentric with the rotational axis and non-cylindrically-symmetrical about the rotational axis.
