Abstract

Claims (27)

1. A method for assembling a suspension having a first suspension component including at least a first and a second opening therein with a first and a second second suspension component, wherein a first suspension component is upon assembly secured in the first opening and the second suspension component is secured in the second opening, comprising:

establishing a temperature difference between the first suspension component and the second suspension components;

securing the first of the second suspension components adjacent to, and aligned for placement into, the first opening;

securing the second of the second suspension components adjacent to, and aligned for placement into, the second opening;

controllably moving the secured first and second second suspension components relative to the first suspension component, such that the first of the second suspension components is received within the first opening and the second of the second suspension components is received within the second opening while the temperature difference between the first suspension component and the second suspension components is present; and

releasing, from the secured state, the first and second suspension components after the receipt thereof in the openings.

2. The method of claim 1 , wherein the components are engaged in a telescopic relationship such that, upon the first and second suspension components achieving an equal temperature, the components comprise a press-fit between a female portion of the first component and male portion of the second component components.

3. The method of claim 2 , wherein the first component is a crown and the second components are fork tubes.

4. The method of claim 3 , wherein the temperature difference between the crown and the fork tubes is created by heating the crown.

5. The method of claim 4 , wherein the crown is located in a fixture, the fixture fixing the crown in a position relative to the fork tubes whereby, when fixed, a centerline of the male portion of the fork is aligned with a centerline of the opening in the female portion of the crown.

6. The method of claim 1 , wherein the steps of securing the first of the second suspension components adjacent to, and aligned for placement into, the first opening and securing the second of the second suspension components adjacent to, and aligned for placement into, the second opening includes positioning the first and second suspension components into different retainers.

7. The method of claim 6 , further including the step of moving the retainer securing the first and second second suspension components in the direction of the first suspension components while the temperature difference between the first suspension component and the second suspension components is present.

8. The method of claim 7 , further including the step of, while moving the retainer securing the first and second second suspension components in the direction of the first suspension components while the temperature difference between the first suspension component and the second suspension components is present, engaging an end of the first and second second components against a ledge projecting radially inwardly of the first and second openings of the first component.

9. The method of claim 8 , whereupon when the ends of the first and second second suspension components engage the ledge in the first and second openings of the first component, a portion of the first second suspension component extends inwardly of, and is spaced from the sidewall of, the first opening by a gap.

10. The method of claim 8 , further including the step of removing the second suspension components from the retainers after the difference in temperature between the first suspension component and the second suspension components is less than that during movement of the first and second second suspension components inwardly of the openings in the first suspension component.

11. The method of claim 1 , wherein an outer surface of the second suspension components is coated with a corrosion resistant material.

12. The method of claim 3 , wherein the openings in the crown have a first diameter and the fork tubes have an outer diameter, and, when the fork tubes and crown are at the same temperature, the outer diameter of the fork tubes is greater than the first diameter of the openings in the crown.

13. A method for assembling a suspension, having a first suspension component including at least a first and a second opening therein having an inner wall, with a first and a second second suspension component having an outer wall, wherein a first suspension component is, upon assembly, secured in the first opening and the second suspension component is secured in the second opening, comprising:

creating a temperature difference between the first and second suspension components such that a portion of the second suspension components may be received within the openings in the first suspension component without the outer wall of the second suspension components contacting the inner wall of the first or second openings,

aligning the second suspension components with respect to the openings in the first suspension component,

simultaneously moving the second suspension components with respect to the first suspension component without altering the alignment of the second suspension components with respect to the openings in the first suspension component,

such that ends of the second suspension components enter into the openings in the first suspension component, with a gap between the outer wall of the second suspension components and the inner wall of the openings.

14. The method of claim 13 , further including the step of aligning the outer suspension components to the openings in the first suspension component as the second suspension components are moving with respect to the first suspension component.

15. The method of claim 14 , wherein the aligning of the second suspension components to the openings in the first suspension component includes the step of aligning an inner diameter of the second suspension components.

16. The method of claim 14 , wherein the second suspension components are secured in retainers prior to the step of aligning the second suspension components to the openings in the first suspension component.

17. The method of claim 13 , wherein the outer surface of the second suspension components includes a coating thereon subject to galling.

18. The method of claim 16 , wherein the retainers move simultaneously to simultaneously move the second suspension components with respect to the first suspension component.
