Figure 1 below shows an approximate timeline for the completion of various aspects for the project. Small percentage of the car s.
Hydraulic jacksdepend on force generated by pressure.
Car jack design. Car jacks use mechanical advantage to allow us to lift a vehicle by manual force alone. A jack is a mechanical lifting device used to apply great forces or lift heavy loads. A mechanical jack employs a screw thread for lifting heavy equipment.
Wonderful homemade jack for car mr suny. Hydraulic jacktend to be stronger and can lift heavier loads higher and include bottle jacks and floor jacks. In this tutorial video i will show you how to design and assemble a car jack in solidworks i hope you will enjoy the tutorial please subscribe our channel for more videos projects in.
The jack was built to a fairly simple design the user rotates the crank arm which rotates the threaded rod causing the arms to be pulled together raising the top of the jack and in turn the car. Design details of jack the total height of the screw jack 276 mm. More powerful jacks use hydraulic power to provide more lift over greater distance.
A scissor jack is a device constructed with a cross hatch mechanism much like a scissor. Permanent set in y direction is 0 37 mm. Unsubscribe from mr suny.
Principle of operation of the motorised screw jack in operation the jack will lift a load in contact with the load platform when the power screw is rotated. A hydraulic jack uses hydraulic power. Mechanical jacks such as car jacks and house jacks lift heavy equipmentand are rated based on lifting capacity for example the number of tons they can lift.
Jacks employ a screw thread or hydraulic cylinder to apply linear forces. 12v dc electric scissor car jack build at home duration. Dk diy 720 055 views.
Design a car jack that is easier to operate and safer to use than the current standard without compromising cost or storage and without adding significant weight. The disassembly gave us a good idea of what role each component plays and what effect they have on the complete device. Modelling design of scissor jack is done with pro e and model assembly is shown in figures 1 to 3.
The deformation of the screw jack in y direction 2 00 mm. The most common form is a car jack floor jack or garage jack which lifts vehicles so that maintenance can be performed. Scissor jacks are simple mechanisms used to drive large loads short distances the power screw design of a common scissor jack reduces the amount of force required by the user to drive the mechanism most scissor jacks are similar in design consisting of four main members driven by a power screw.
Existing design of car jack by incorporating an electric motor into the existing screw jack to make the operation easier safer faster and more reliable.
