Abstract
A vehicle frame system includes a lower cross frame assembly that is coupled with an axle and includes a frame bar extending between a first end and a second end along a first axis. The frame bar includes a first external circumferential surface extending along at least a portion of the first axis. A first sleeve is configured to be disposed over the first external circumferential surface. A first internal surface of the first sleeve is operably coupled with the first external circumferential surface of the frame bar. The first sleeve is configured for a temperature of the first sleeve to be controlled to change one or more characteristics of the first sleeve. The first sleeve is prohibited from moving relative to the frame bar responsive to changing the one or more characteristics of the first sleeve.
Claims19
A vehicle frame system comprising:
- a lower cross frame assembly configured to be coupled with an axle, the lower cross frame assembly comprising:
- a frame bar extending between a first end and a second end of the frame bar along a first axis, the frame bar having a first external circumferential surface extending along at least a portion of the first axis;
- and
- a first sleeve configured to be disposed over the first external circumferential surface, wherein a first internal surface of the first sleeve is configured to be operably coupled with the first external circumferential surface of the frame bar;
- wherein the first sleeve is configured for a temperature of the first sleeve to be controlled to change one or more characteristics of the first sleeve, wherein the first sleeve is prohibited from moving relative to the frame bar responsive to changing the one or more characteristics of the first sleeve;
- and
- a guide assembly operably coupled with the lower cross frame assembly, the guide assembly comprising:
- a guide tube extending between a first end and a second end of the guide tube along a second axis;
- and
- a second sleeve configured to be disposed within a portion of the guide tube, wherein the second sleeve is configured for a temperature of the second sleeve to be controlled to change one or more characteristics of the second sleeve, wherein the second sleeve is prohibited from moving relative to the guide tube responsive to changing the one or more characteristics of the second sleeve.
A vehicle frame system comprising:
- an axle extending between a first end and a second end, a first guide wheel operably coupled with the first end of the axle and a second guide wheel operably coupled with the second end of the axle;
- a lower cross frame assembly operably coupled with the axle, the lower cross frame assembly comprising:
- a frame bar extending between a first end and a second end of the frame bar along a first axis;
- and
- a first sleeve and a second sleeve respectively disposed over the first end and the second end of the frame bar;
- and
- a first guide assembly operably coupled with the first end of the frame bar and a second guide assembly operably coupled with the second end of the frame bar, each of the first and second guide assemblies respectively comprising:
- a guide tube extending between a first end and a second end of the guide tube along a second axis;
- and
- a third sleeve disposed within a portion of the guide tube, wherein the first and second sleeves are interference fit with the frame bar and the third sleeve is interference fit within the guide tube so that the first and second sleeves are prohibited from moving relative to the frame bar and the third sleeve is prohibited from moving relative to the guide tube.
A railgear for a hi-rail vehicle comprising:
- an axle extending between a first end and a second end, a first guide wheel operably coupled with the first end of the axle and a second guide wheel operably coupled with the second end of the axle;
- a lower cross frame assembly operably coupled with the axle, the lower cross frame assembly comprising a frame bar extending between a first end and a second end of the frame bar along a first axis, a first sleeve disposed over the first end of the frame bar and a second sleeve disposed over the second end of the frame bar;
- an upper cross frame assembly, wherein the lower cross frame assembly is rotatable relative to upper cross frame assembly about the first axis;
- an actuator device operably coupled with the lower cross frame assembly and configured to control movement of the axle between different states of the axle by rotating the lower cross frame assembly relative to the upper cross frame assembly;
- and
- first and second guide assemblies operably coupled with the first and second ends of the frame bar, each of the first and second guide assemblies respectively comprising a guide tube extending between a first end and a second end of the guide tube along a second axis and a third sleeve disposed within a portion of the guide tube,
- wherein the first sleeve and the second sleeve are interference fit on to the first and second ends of the frame bar respectively, and the third sleeve of each of the first and second guide assemblies is interference fit within the guide tube, so that the first and second sleeves and the third sleeve are prohibited from moving relative to the frame bar and the guide tube, respectively.
