In the Daf 600 the Continuously Variable Transmission was still called Variomatic. Soon the nickname ‘the clever stick’ came about. You could go forward and backward. It didn’t get any easier! A Daf was therefore quickly seen as a car for elderly ladies and nuns. That earned him the nickname ‘bitch shaker with suspender drive’.
Reverse in On land, at sea and in the air
The Variomatic did exactly the same in both directions of rotation. This way you could drive forward as fast as backwards with a Daf. Many Dafs have died on the ‘reversing’ part of the television program On land, at sea and in the air. André van Duin then commented.
The inventor of the Variomatic is Hub van Doorne
The first patent for a continuously variable transmission was issued in 1877. The inventor of the modern CVT is the Dutch Hub van Doorne, co-founder and technical conscience of the Van Doorne’s Automobielfabriek (DAF) in Eindhoven. In 1972 Van Doorne’s Transmissies was established in Tilburg. The company has been part of Bosch since 1995.
A quarter of all machines are CVT gearboxes
Bosch Transmission Technology has now produced 80 million push belts for CVTs. A quarter of all automatic transmissions built annually is a CVT. Bosch says that with the CVT a 15% lower consumption is achievable than with a manual gearbox.
De Daf 55 in de London to Sydney Marathon
The first Variomatics had rubber belts, from 1970 a push belt with steel links was used. To boost the image of the Variomatic, Daf started in 1968 with two cars in the 16,500 kilometer long London to Sydney Marathon. Both Dafs 55 came to the finish. Later, the sporty Daf models were given the name ‘Marathon’.
Continuously Variable Transmission in Formula 1
Daf was also successful in Formula 3 with the Variomatic. Gijs van Lennep was one of the drivers who came out for Daf. The Williams Formula 1 team tested a CVT in a car with 850 hp V10 engine in 1993. Automatic transmissions were banned before the start of the new F1 season. The Williams-Renault FW15C with CVT is now on display in the Daf Museum in Eindhoven.
