Abstract

A kingpin removal system including a cart assembly having one or more wheels and a yoke assembly carried by the cart assembly and positionable around a steering spindle of a vehicle'"'"'s wheel end assembly. The yoke assembly can include a pair of plates interconnected by a pair of rods. An intermediate plate is positioned between the pair of yoke plates. A wheel end support mechanism can be carried by the cart assembly and a hub mounting ring can be carried by the wheel end support mechanism. The hub mounting ring can be positioned to connect to and support the wheel end assembly once the kingpin is removed.

Claims

1. A kingpin removal system, comprising:

a cart assembly including one or more wheels and a gimbal assembly, the gimbal assembly including a gimbal pin having a frustoconical surface configured to tilt in any direction;

a yoke assembly carried by the gimbal assembly and positionable around a steering spindle of a wheel end assembly, the yoke assembly including a pair of yoke plates interconnected by a pair of rods;

an intermediate plate positioned between the pair of yoke plates;

a wheel end support mechanism carried by the cart assembly; and

a hub mounting ring carried by the wheel end support mechanism, the hub mounting ring being positioned to connect to and support the wheel end assembly.

2. The system of claim 1, further comprising a press positionable on one of the pair of yoke plates between the pair of rods and operable to push against a kingpin of the wheel end assembly.

3. The system of claim 1, further comprising a pair of support tubes, each positioned on a corresponding one of the pair of rods and between the intermediate plate and one of the pair of yoke plates.

4. The system of claim 1, wherein the wheel end support mechanism is pivotably coupled to the cart assembly.

5. The system of claim 1, wherein the hub mounting ring is pivotably coupled to the wheel end support mechanism.

6. The system of claim 1, wherein the wheel end support mechanism includes a strut tube, a lift tube, and a lifting mechanism positioned to move the lift tube relative to the strut tube.

7. A kingpin removal system, comprising:

a cart assembly including one or more wheels;

a gimbal assembly including;

a frame slidably positioned on the cart assembly a gimbal carriage retained on the frame; and

a gimbal pin having a frustoconical surface, configured to tilt in any direction relative to the gimbal carriage, carried by the gimbal carriage;

a yoke assembly carried by the gimbal pin and positionable around a steering spindle of a wheel end assembly, the yoke assembly including a pair of plates interconnected by a pair of rods;

a wheel end support mechanism pivotably coupled to the cart assembly; and

a hub mounting ring pivotably coupled to the wheel end support mechanism, the hub mounting ring being positioned to connect to and support the wheel end assembly.

8. The system of claim 7, further comprising a press positionable on one of the pair of plates between the pair of rods and operable to push against a kingpin of the wheel end assembly.

9. The system of claim 7, wherein the wheel end support mechanism includes a strut tube, a lift tube, and a lifting mechanism positioned to move the lift tube relative to the strut tube.

10. The system of claim 7, wherein the wheel end support mechanism and the hub mounting ring each pivot about corresponding orthogonal axes.
