Wolfgang Kröber

from Wikipedia, the free encyclopedia

Wolfgang Kröber (* in Winningen on the Moselle; † 1981 ) was a German electrical engineer , motorcyclist and electronics technician . In the mid-1960s, he developed an electronic tachometer for motorcycles and was a pioneer in vehicle electronics .

Act

Through his hobby, riding a motorcycle off-road, Kröber was repeatedly confronted with the weak points of the mechanical measuring devices. In particular, the angular drive for the tachometer shaft often broke off and led to unplanned repairs to the speedometer .

With the aim of electrically transmitting, evaluating and displaying an electrical signal from the engine speed, and to be able to do without a mechanical " speedometer cable " that mechanically transfers the engine speed from the crankshaft or camshaft , Kröber developed an electronic tachometer. While previous speedometer cables and rev counter shafts required lubrication, could wear out and eventually fail with a defect, the electronic solution did not have these problems.

Kröber's retrofittable electronic tachometers were an important accessory on the motorcycle for many committed motorcyclists in the years between 1962 and 1980. They are still made today using the same scheme. In 1964, Kröber went into business for himself with the production of electronic tachometers. From 1968 he also built electronic ignitions for motorcycles that were more precise and up to 30 percent more powerful than the original ignition systems from many series manufacturers , which were mechanically controlled by an ignition contact .

Wolfgang Kröber died in 1981. His business was continued by an acquaintance and friend, Herbert Pitsch. In 2016 the company was transferred to Hertogs Willy Belgie HPI .

Since around 1985, hardly any vehicles have been built that have mechanically driven display instruments. Today's motor vehicles all use electronically generated signals on the engine, gearbox, wheels, tanks, etc. to display information to the driver. Speedometers, rev counters, temperature, time and fuel displays and other things are nowadays processed electronically as a matter of course. Modern vehicles would be inconceivable without electronic sensors and signal transmission. Wolfgang Kröber was thus a pioneer in vehicle electronics.
