Abstract
A dual cylinder jack with interchangeable attachments is provided. The jack includes a jack assembly having a base which supports a lower pneumatic stage and an upper hydraulic stage. The distal end of the jack assembly receives a jig carriage for coupling a particular vehicle part jig to the jack assembly for use. The various part jigs are adapted and designed to cooperate with specific parts of a vehicle in mating fashion.
Claims18
A mechanism for raising and lowering parts of a vehicle during service thereon, the mechanism comprising:
- a jack assembly having a mobile base with a jack portion supported thereon in a generally upright position, wherein the jack portion has a piston and a cylinder, a portion of the piston being slidably received in the cylinder and movable along a longitudinal axis of the jack assembly between extended and retracted positions, and wherein the piston has a distal end opposite the portion received in the cylinder;
- a jig carriage coupled with the distal end of the piston and having a body and an arm, the arm having a proximal end which is pivotally coupled with the body and a distal end, wherein the distal end of the arm of the jig carriage includes a bore therethrough;
- and
- a vehicle part jig removably coupled with the distal end of the arm of the jig carriage, wherein the jig is a clutch jig for adapting the mechanism to couple with a clutch of the vehicle to support and align the components of the clutch during assembly, disassembly and repair, wherein the clutch jig is an elongate cylindrical member having a longitudinal axis, and wherein the clutch jig has a plurality of splines on an exterior surface thereof for sliding engagement with the vehicle clutch, the splines being generally parallel to the longitudinal axis of the clutch jig, wherein the clutch jig includes a shaft and a sleeve, the sleeve being rotatably and removably received on the shaft, wherein the splines are located on an exterior surface of the sleeve, and wherein the clutch jig is coupled with the jig carriage by a proximal end of the shaft being removably received in the bore of the jig carriage.
A mechanism for raising and lowering parts of a vehicle during service thereon, the mechanism comprising:
- a jack assembly having a mobile base with a jack portion supported thereon in a generally upright position, wherein the jack portion has a piston and a cylinder, a portion of the piston being slidably received in the cylinder and movable along a longitudinal axis of the jack assembly between extended and retracted positions, and wherein the piston has a distal end opposite the portion received in the cylinder;
- a jig carriage coupled with the distal end of the piston and having a body and an arm, the arm having a proximal end which is pivotally coupled with the body and a distal end;
- and
- a vehicle part jig removably coupled with the distal end of the arm of the jig carriage, wherein the jig is a flywheel jig for adapting the mechanism to couple with a flywheel of the vehicle to support and align the components of the flywheel during assembly, disassembly and repair, wherein the flywheel jig has a hub with a plurality of mounting bars extending therefrom at a distal end, each of the mounting bars having distal ends spaced apart from the hub, wherein the flywheel jig is coupled to the distal end of the arm of the jig carriage at a proximal end of the hub, and wherein the distal ends of the mounting bars include an aperture therethrough to facilitate coupling the flywheel jig with the flywheel.
A mechanism for raising and lowering parts of a vehicle during service thereon, the mechanism comprising:
- a jack assembly having a mobile base with a jack portion supported thereon in a generally upright position, wherein the jack portion has a piston and a cylinder, a portion of the piston being slidably received in the cylinder and movable along a longitudinal axis of the jack assembly between extended and retracted positions, and wherein the piston has a distal end opposite the portion received in the cylinder;
- a jig carriage coupled with the distal end of the piston and having a body and an arm, the arm having a proximal end which is pivotally coupled with the body and a distal end;
- and
- a clutch jig removably coupled with the distal end of the arm of the jig carriage for adapting the mechanism to couple with a clutch of the vehicle, wherein the clutch jig is an elongate cylindrical member having a longitudinal axis, wherein clutch jig includes a shaft and a sleeve, the sleeve being rotatably and removably received on the shaft, and wherein the clutch jig has a plurality of splines located on an exterior surface of the sleeve for sliding engagement with the vehicle clutch, the splines being generally parallel to the longitudinal axis of the clutch jig.
A mechanism for raising and lowering parts of a vehicle during service thereon, the mechanism comprising:
- a jack assembly having a mobile base with a jack portion supported thereon in a generally upright position, wherein the jack portion has a piston and a cylinder, a portion of the piston being slidably received in the cylinder and movable along a longitudinal axis of the jack assembly between extended and retracted positions, and wherein the piston has a distal end opposite the portion received in the cylinder;
- a jig carriage coupled with the distal end of the piston and having a body and an arm, the arm having a proximal end which is pivotally coupled with the body and a distal end;
- and
- a flywheel jig removably coupled with the distal end of the arm of the jig carriage for adapting the mechanism to couple with a flywheel of the vehicle, wherein the flywheel jig has a hub with a plurality of mounting bars extending therefrom at a distal end, wherein each of the mounting bars have a distal end spaced apart from the hub, wherein the flywheel jig is coupled to the distal end of the arm of the jig carriage at a proximal end of the hub, and wherein the distal ends of the mounting bars include an aperture there through to facilitate coupling the flywheel jig with the flywheel.
