DA,F was 4th Gear semantics

PostPost by: c.beijersbergen » Tue Feb 07, 2006 12:09 pm

DAF besides its lorry section had a series of small cars, the Daffodil, the 33, 44, 55 and 66. All these cars had a continiously variable automatic transmission based on rubber belts. In the late 60's DAF ran a F3 (1L, Cosworth SCA ca. 110 hp) racing team with cars with these transmissions, they performed rather well.

The passenger car department of DAF was sold to Volvo. They designed and produced the Volvo 300 (based on a DAF 77 design) and 400 series of somewhat larger cars. The 300 had a choice of the DAF transmission or a manual Volvo transmission. After considerable time the design department in the Netherlands was dismantled and the production facilities sold to Mitsubishu under the name of Nedcar. The Volvo V40/S40 was produced there together with a Mitsubishu on the same assembly line.Now the Smart for Four is produced on this line.

After DAF passenger cars were sold to Volvo a new company was grounded in the Netherlands to continiou the work done on next generation continiously variable automatic transmissions. This company is called VDT (Van Doorne's Transmissies). This new generation of transmissions is based on a more complex metal belt. VDT supplies these metal belts to a lot of car and transmission producers in the world. Power rating for these new transmissions is much larger than for the older DAF transmission. Already tests have been done with F1 power trains.

Yes, I know of NEDCAR. They have some of our markers.

I have not been following this email thread but when I saw DAF I had to take
a peak.



In the mid-'70's I ran rallies in Belgium, Flemish part. I had a 1300cc
Lancia Fulvia. There was a guy with an 1100cc DAF that was very specially
prepared. I do not know if he had connections at the factory or not. The
motor was prepared to Group 2 rules of the time which meant it was quite
powerful for 1100cc. The big mods were to the transmission controls. It
was set up to keep the motor at max RPM whenever he was at full throttle,
since he used left foot braking that was nearly 100% of every stage. I was
glad he was in a lower class; the car and driver were very fast!



How did this get on a Lotus page??

Hello Ken,


Cor

I have not been following this email thread but when I saw DAF I had to take
a peak.



In the mid-'70's I ran rallies in Belgium, Flemish part. I had a 1300cc
Lancia Fulvia. There was a guy with an 1100cc DAF that was very specially
prepared. I do not know if he had connections at the factory or not. The
motor was prepared to Group 2 rules of the time which meant it was quite
powerful for 1100cc.
The motor DAF used came from Renault, so for rallying there was an option of using the Gordini version of this motor, which was used in Renault Alpine A110's or Matra Jet's. These DAF's (I believe they were 66 Coup?'s) were very fast indeed, also reliable, because one finished the London Sydney Marathon.

The big mods were to the transmission controls. It
was set up to keep the motor at max RPM whenever he was at full throttle,
since he used left foot braking that was nearly 100% of every stage.
The engine was kept at max. power rpm all the time. This is a nice feature of this type of automastic transmission, one can control the powertrain characteristic by the control unit, certainly nowadays with more electronics available. In one car one can change from a continiously variable drive to a 6 or 7 gear drive with distinct fixed reduction ratio's by a deashboard switch.



I was
glad he was in a lower class; the car and driver were very fast!



How did this get on a Lotus page??
Somebody started this discussuion by stating that the term "fourth gear" for fourth gear in an Elan box is not right because no gears are involved. This brought us to car transmissions where no gears at all are involved, you see?

I see. Any comments on the rally car I described?



By the way, do you know Cor Euser? I raced with him in the early ?80?s,
FF2000. Guess Cor is a relatively common Dutch name.
