Design & Development of Button Operated Electro Hydraulic Jack

Car jack is an important element in the maintenance and removal of car tyres. The conventional jacks in use are toggle jack, hydraulic jack, screw jack etc. Normally the jacks are operated manually. In case of commercial cars use the toggle jack for lifting the car for removal of tyres. The toggle jack is manually operated although motorized toggle jack are also available. The toggle jack is a spare element which can be placed under an individual tyre location that needs to be replaced. The toggle jacks are cuber some to operate especially to female drivers and hence a more simple to operate motorized hydraulic jack that will be compact, handy, with low storage space is required. The need of an integrated hydraulic jack in the motorized form is needed where in the lifting capacity of the jack be at least 1 ton, the drive motor be suitable connected via linkage to the operating handle of the hydraulic jack pump and the power be delivered to the motor through suitable electric circuit with 12 volt DC power that can be taken from the car battery through the cigarette lighter socket below dash board. The design of the hydraulic jack, motor drive and kinematic linkage to operate the pump is done using theoretical method and the 3-d model is developed using Unigraphix NX-8 and the analysis of the parts is done using Ansys 16.0 The testing has been done in suitable manner to demonstrate the capability of jack.
