Abstract
An emergency axle lift control for a vehicle having at least one supplemental load axle configured to provide supplemental support to the vehicle by moving from a stored position in which wheels of the supplemental load axle do not contact the ground surface to a deployed position in which the wheels of the supplemental load axle contact the ground surface. The emergency axle lift control may comprise a control bypass switch operable by an operator of the vehicle while driving the vehicle, with the control bypass switch being configured to cause all of the supplemental load axles of the vehicle to move from the deployed position toward the stored position when the operator actuates the control bypass switch.
Claims17
A system comprising:
- a vehicle comprising:
- a frame with a front and a rear,
- at least two support axles mounted on the frame and including at least a pair of wheels per support axle;
- at least one supplemental load axle mounted on the frame and including at least two wheels per supplemental load axle configured to selectively contact the ground surface below the vehicle to provide supplemental support to the frame, the at least one supplemental load axle being moveable between a deployed position in which the wheels of the supplemental load axle contact the ground surface and a stored position in which the wheels do not contact the ground surface;
- an axle actuation apparatus configured to selectively move the at least one supplemental load axle between the stored position and the deployed position, a said axle actuation apparatus being provided to move each one of the at least one supplemental load axles;
- a primary control assembly configured to control the axle actuation apparatus, a said primary control assembly being provided for each said axle actuation apparatus, the primary control assembly comprising a control switch connected to a power source and to the axle actuation apparatus to selectively control supply of power to the axle actuation apparatus to operate the actuation apparatus to move the at least one supplemental load axle from the stored position to the deployed position and from the deployed position to the stored position;
- and
- an emergency axle lift control configured to cause all of the supplemental load axles on the vehicle to be moved from the deployed position toward the stored position, the emergency axle lift control comprising a control bypass switch operable by an operator of the vehicle while driving the vehicle and configured to cause all of the supplemental load axles of the vehicle to move from the deployed position toward the stored position when the operator actuates the control bypass switch.
An emergency axle lift control for a vehicle having at least one supplemental load axle configured to provide supplemental support to the vehicle by moving from a stored position in which wheels of the supplemental load axle do not contact the ground surface to a deployed position in which the wheels of the supplemental load axle contact the ground surface, the emergency axle lift control comprising:
- a control bypass switch operable by an operator of the vehicle while driving the vehicle, the control bypass switch being configured to cause all of the supplemental load axles of the vehicle to move from the deployed position toward the stored position when the operator actuates the control bypass switch;
- wherein the control bypass switch is connected to a battery of the vehicle without fuse overcurrent protection.
An emergency axle lift control for a vehicle having at least one supplemental load axle configured to provide supplemental support to the vehicle by moving from a stored position in which wheels of the supplemental load axle do not contact the ground surface to a deployed position in which the wheels of the supplemental load axle contact the ground surface, the emergency axle lift control comprising:
- a control bypass switch operable by an operator of the vehicle while driving the vehicle, the control bypass switch being configured to cause all of the supplemental load axles of the vehicle to move from the deployed position toward the stored position when the operator actuates the control bypass switch;
- wherein the vehicle includes an axle actuation apparatus configured to selectively move the at least one supplemental load axle between the stored position and the deployed position, a said axle actuation apparatus being provided to move each one of the at least one supplemental load axles, and a primary control assembly configured to control the axle actuation apparatus, a said primary control assembly being provided for each said axle actuation apparatus, the primary control assembly comprising a control switch connected to a power source and to the axle actuation apparatus to selectively control supply of power to the axle actuation apparatus to operate the actuation apparatus to move the at least one supplemental load axle from the stored position to the deployed position and from the deployed position to the stored position;
- and
- wherein the control bypass switch bypasses the primary control assembly to operate the axle actuation apparatus.
An emergency axle lift control for a vehicle having at least one supplemental load axle configured to provide supplemental support to the vehicle by moving from a stored position in which wheels of the supplemental load axle do not contact the ground surface to a deployed position in which the wheels of the supplemental load axle contact the ground surface, the emergency axle lift control comprising:
- a control bypass switch operable by an operator of the vehicle while driving the vehicle, the control bypass switch being configured to cause all of the supplemental load axles of the vehicle to move from the deployed position toward the stored position when the operator actuates the control bypass switch;
- wherein the control bypass switch is incapable of causing the at least one supplemental load axle to move from the stored position to the deployed position.
