Rim Blow $37. A rubber pad encasing wires was mounted around the entire inner surface of the steering wheel rim. Rather than pressing a suspended horn ring, a center horn pad, or switches on the spokes, to make the electrical contact, the inside of the rim could be pressed anywhere on its circumference. Applying pressure to soft rubber inner rim of the steering wheel, a driver could activate the car's horn without moving their hands from the wheel rims. Technical issues, such as hardening (difficult to activate) and shrinking (causing the horn to sound without activation) of the rubber, and a lack
Wheel hub motor part of the motor follows, or tries to follow, those fields, turning the attached wheel. In a brushed motor, energy is transferred by brushes contacting the rotating shaft of the motor. Energy is transferred in a brushless motor electronically, eliminating physical contact between stationary and moving parts. Although brushless motor technology is more expensive, most are more efficient and longer-lasting than brushed motor systems. A hub motor typically is designed in one of three configurations. Considered least practical is an axial-flux motor, where the stator windings are typically sandwiched between sets of magnets. The other two configurations are both radial
