Abstract

Claims (42)

1. A wheel stud press assembly for displacing a wheel stud relative to a wheel opening in a wheel flange comprising:

a frame assembly defining a drive axis, the frame assembly comprising a frame member defining a main portion and a shoulder portion and an anchor member detachably attached to the frame member; and

a drive system comprising a drive rod, where the drive system is supported by the shoulder portion of the frame member to displace the drive rod along the drive axis; whereby

the frame member is configured such that, when the anchor member is detachably attached to the frame member, the drive axis is offset from the main portion of the frame member; and

when the drive rod engages the wheel stud to force the wheel stud out of the wheel opening,

at least a portion of the anchor member engages wheel flange adjacent to the wheel stud to allow the wheel stud to be forced out of the wheel opening, and

the anchor portion is offset from the drive axis to allow the wheel stud to be displaced out of the wheel opening.

2. A wheel stud press assembly as recited in claim 1 , in which:

the anchor member defines first and second arm portions; and

the anchor member is arranged such that, when the anchor member engages the wheel flange, the drive axis extends between the first and second arm portions such that the wheel stud is displaced out of the wheel opening between the first and second arm portions.

3. A wheel stud press assembly as recited in claim 1 , in which:

the frame member further defines a threaded opening;

the drive rod defines a threaded surface; and

the threaded surface engages the threaded opening such that axial rotation of the drive rod relative to the frame assembly displaces the drive rod along the drive axis.

4. A wheel stud press assembly as recited in claim 1 , in which:

the drive system further comprises a drive cylinder supported by the frame member;

the drive cylinder supports the drive rod to define a drive chamber; and

pressurized fluid within the drive chamber acts on the drive rod to displace the drive rod along the drive axis.

5. A wheel stud press assembly as recited in claim 4 , further comprising a return spring for biasing the drive rod into a retracted position relative to the drive cylinder.

6. A wheel stud press assembly as recited in claim 1 , further comprising:

a space plate adapted to engage the anchor member such that the drive axis extends through the space plate; and

a spacer adapted to extend around a portion of the wheel stud; wherein

when the space plate engages the wheel stud and the spacer engages the drive rod and the wheel flange, operation of the drive system causes the frame assembly to displace the space plate to force the wheel stud into the wheel opening.

7. A method of displacing a wheel stud relative to a wheel opening in a wheel flange comprising the steps of:

providing a frame member defining a main portion and a shoulder portion;

detachably attaching an anchor member to the frame member;

providing a drive system comprising a drive rod;

supporting the drive system on the shoulder portion of the frame member to displace the drive rod along a drive axis, where, when the anchor member is detachably attached to the frame member; and

engaging at least a portion of the anchor member with the wheel flange adjacent to the wheel stud such that the drive axis is offset from the main portion of the frame member and at least a portion of the anchor member; and

operating the drive system to displace the wheel stud out of the wheel opening such that the drive rod engages the wheel stud to force the wheel stud out of the wheel opening.

8. A method as recited in claim 7 , in which the anchor member defines first and second arm portions, the method further comprising the step of arranging the anchor member such that, when the anchor member engages the wheel flange, the drive axis extends between the first and second arm portions such that the wheel stud is displaced out of the wheel opening between the first and second arm portions.

9. A method as recited in claim 7 , in which the frame member further defines a threaded opening and the drive rod defines a threaded surface, the method further comprising the steps of:

engaging the threaded surface with the threaded opening; and

axially rotating the drive rod relative to the frame assembly to displace the drive rod along the drive axis.

10. A method as recited in claim 7 , in which the drive system comprises a drive cylinder supported by the frame member, further comprising the steps of:

supporting the drive cylinder relative to the drive rod to define a drive chamber; and

introducing pressurized fluid within the drive chamber such that the pressurized fluid acts on the drive rod to displace the drive rod along the drive axis.

11. A method as recited in claim 10 , further comprising the step of arranging a return spring to bias the drive rod into a retracted position relative to the drive cylinder.

12. A method as recited in claim 7 , further comprising the steps of:

arranging a space plate to engage the anchor member such that the drive axis extends through the space plate;

arranging a spacer to extend around a portion of the wheel stud such that the space plate engages the wheel stud and the spacer engages the drive rod and the wheel flange; and

operating the drive system to cause the frame assembly to displace the space plate to force the wheel stud into the wheel opening.
