The design of the transmission system for a formula styled racecar using a stock bike engine is one of the best choice for all the engineering students who design the motorsport vehicles for all the student race car build competitions. As there are many rules and restrictions on engine usage such as capacity, maximum power allowed, type of fuel usage permitted and many more. In addition, this report emphasize on the suitable type of transmission system, differential and drivetrain assembly. The present report shows the various considerations, calculations, analysis and various parametric data’s of stock KTM 390 Engine and the drivetrain of the car.To design the components, sub-assemblies and assembly the design software’s NX CAD and SolidWorks are used, ...

Problem Statement:
Generally, Heavy Duty Trucks are used for transportation purpose of cargo with heavy loads and therefore, require a robust steering control (i.e. lateral stability) all the time (especially when moving at a high speed or during cornering) in order to ensure safety of the on-board crew, loaded goods and vehicle itself. Generally the steering system of the trucks is hydraulically assisted and this assistance is provided by a hydraulic pump which is driven by the main engine. Now the problem is, if this engine fails for any reason then there will be no more hydraulic assistance and it might put in a dangerous situation because it will be very difficult to handle that much load mechanically. Therefore ...

Scientists estimate that there are about 10 zillion (10x10^16) fish in the sea, which is more than 1 million fish for every human. About 95% of these fish live deeper than 500 meters under the sea. All of these fish require oxygen to breathe. They do not split water molecules into Hydrogen and Oxygen; rather they breathe the oxygen from air that is dissolved in the water. Separation of dissolved air from water is simpler, and requires much less energy, than splitting water molecules (which is the way that nuclear submarines supply oxygen to their crews). All that is needed to release the dissolved air is to lower the pressure on a body of water ('Henry's Law'). An example ...

The innovation - named "SafeTank" - is a dual-compartment liquid tank assembly, consisting of an upper chamber and a lower chamber, that are secured together, in a leak-proof manner. Between the two chambers is a flexible membrane. Each chamber has an inlet port and an outlet port.

The tank assembly is primarily intended for use in towable RV’s (recreational vehicles) - but can be used for marine applications - for holding, but separating, clean (“fresh”) water and dirty (“grey”) water.

The product provides three important benefits to Travel Trailers (Caravans) and Camper-Trailers:

1: It allows the dirty water to be retained in the vehicle, until it can be drained, in a responsible manner.

2: It allows the total mass of ...

What is our project? Design and Development of diff lock through novel spike shaft design mechanism for SUV and Off – Road Vehicles.

Why did we introduce it? In India 70 % are in rural areas, major transportation has been done through pick up van ( Maximo / JITO /TATA ace/Ashok Dost ) i.e. 1 ~ 5 tone application, in 70% rough road contains big digs and ditches while vehicle loaded and moving through same road will lock wheel, so if want to move from there need extra power and that finally got from rear wheel diff lock.

Design Methodology: Design/DFMEA / DVP /CAE Verification /Validation.

Market Available: Eaton / TATA/ Eicher (Hydraulic or Pneumatic operated)

Cost: 47,225 INR.

In this concept will make a motor Electric Car more energy efficient and longer running. First we will make the air tube under the car the size 10 ft L x 4 ft W x 10 in H. At the end of the air tube there will be a rolling fan that is the same size as the air tube with 16 fan blades on the right and left sides of the rolling fan. It will be attached to a spindle gear size 10 in.diameter that weighs 5 lbs each side. The spindle gear will connect to the 5 in. diameter generator. When the car moves, the wind will flow to the rolling fan blades and the rolling fan ...

Forest dwellers (Tribal) are dependent on forest for their livelihood. Wild life safari provides a much needed source of sustainable income without dislodging them from their environment. However, the vehicular movement causes pollution at highly ecosensitive places. Presently, a 4x4 army disposal vehicle is used for this purpose. We have created a "bolt on kit" that replaces the engine of this car with an electric motor. The conversion is done at the forest, by the forest dwellers who are trained by our team. The battery is re-charged by solar panels. The charging stations are also erected and managed by tribal. The motor is water proof. All electronics are encased in a waterproof container. Non interchangeable MIL grade connectors provide ...

Our company, Potential Difference Inc., is now commercializing a new electric vehicle generator innovation that reverses the electric vehicle (EV) regenerative braking paradigm and introduces Electric Vehicle Regenerative Acceleration.

As the name implies EV Regenerative Acceleration accelerates the EV while recharging the EV's batteries rather than decelerating it as per EV regenerative braking.

EV regenerative braking occurs as a result of Generator Armature Reaction, which is a Counter-Electromagnetic-Torque produced inside the generator by the magnetic fields which are created around the current bearing wires inside all conventional generators when they are placed on-load and when delivering electric power, in this case to the EV's batteries.

The conventional (regenerative braking) generator's on-load induced counter-electromagnetic-torque performs negative work in opposition (in ...

US Patent no. 9,415,646 states that an automobile and trailer or truck and trailer, first half of which is securely mounted to the rear underside of the automobile or truck, the second half of which is securely mounted to the underside of the trailer. When the trailer is attached to the automobile or truck the two hitch halves interlock. A locking rod is inserted horizontally to cause the hitch to act as a single unit. Horizontal rotation is prevented but the trailer is able to pivot vertically around the locking rod to compensate for the trailer going over bumps in the road.

It is novel in that no apparatus exists which totally eliminates jack-knifing. It would be produced by ...

It’s a vehicle that can make world a greener place to live in. This lightweight (approx. 60 kg) EM-trike is a highly engineered one seater hybrid vehicle with electric +manpower to operate it. Along with the quirky looks, its technical specifications provides comfort as well as satisfaction to the user. It has a tadpole design configuration which means two wheels in front and one in the rear. It’s equipped with a powerful spring +damper suspension in the rear, 8-speed sprocket for varying torque, disk brakes in the front and rear wheels. It has wide tires for more traction. It has an indirect Ackerman steering system with a steering ratio of 1.5 for ease. It can carry loads up to ...
