The account of the JATO Rocket Car was one of the original Darwin Awards winners: a man who supposedly met his death in a spectacular manner after mounting a JATO unit (a rocket engine used to help heavy aircraft to take off) onto an ordinary automobile.
A two-wheel drive vehicle has two driven wheels, typically both at the front or back, while a four-wheel drive has four. A steering wheel is a wheel that turns to change the direction of a vehicle. A trailer wheel is one that is neither a drive wheel, nor a steer wheel. Front-wheel drive vehicles typically have the rear wheels as trailer wheels.
The name is an abbreviation of Universal Wheel Drive System. [2] The Uni Wheel is intended to gain the advantages of individual wheel drive without having to mount the motor directly to, or inside, the wheel. Instead, it subsumes the functions of constant-velocity joints, drive shaft and reduction gearing into a single system within the wheel. [1]
This both improves drive-wheel traction and reduces the tendency for the undriven wheels to dig in. In addition, the driving and steering requirements are split between front and rear- as with FR vehicles- making it less likely for either to lose traction. Many dune buggies successfully use a Volkswagen beetle as the donor car for this reason ...
Conversely, under braking, weight transfer toward the front of the car can occur. Under hard braking it might be clearly visible even from inside the vehicle as the nose dives toward the ground (most of this will be due to load transfer). Similarly, during changes in direction (lateral acceleration), weight transfer to the outside of the ...
Jackshaft drive and coupling rods were used in the past [5] [6] (e.g. in the Swiss Crocodile locomotive [7]) but their use is now confined to shunter locomotives. On an articulated locomotive or a duplex locomotive, driving wheels are grouped into sets with wheels within each set linked together.
Here's another item to add to the list of things you shouldn't try at home: tossing your plastic water bottle into molten hot steel.
A two-wheel-drive bicycle with the front wheel propelled by the arms and the rear wheel by the legs (demonstrated by its Dutch inventor on Polygoon, 1942). For two-wheeled vehicles such as motorcycles and bicycles, the term is used to describe vehicles that can power the front as well as the back wheel.
