The BMW F 76 was a small three-wheel delivery van that BMW built in Eisenach from 1932 to 1933 . In 1933 he was given the BMW F 79 with a larger engine, which was manufactured until 1934.
history
development
With poor sales of the expensive van version of the BMW 3/15 (with only 435 vehicles from May 1929 to February 1932) during the Great Depression and the simultaneous success of other manufacturers with three-wheeled commercial vehicles , BMW in Munich developed its own "muzzle loader" with two side-by-side from 1931 Seating using the existing single cylinder motorcycle engines.
A single-seat variant was tested, but not taken over into series production; just as little as a version as a passenger car.
marketing
The BMW plant in Eisenach built from autumn 1932 F 76 for the license-free vehicle class with a maximum of 200 cc capacity at a retail price of 1,350 Reichsmarks. As early as January 1933, the F 79 followed with a displacement of 400 cm³, which cost 1,500 Reichsmarks. A horn and a speedometer were included in the basic price, but the windshield, windscreen wipers, driver's cab, doors, electrical indicators, spare wheel, spare wheel holder and jack were subject to a surcharge; as well as all modified versions of the loading area.
After only 600 copies (250 F 76 and 350 F 79 ), the construction of the vehicles, which actually came too late for the global economic crisis, was stopped in mid-1934 due to a lack of customer interest.
technology
drive
As single-cylinder four-stroke engines with encapsulated OHV cylinder heads, the engines largely corresponded to the motorcycle engines of the BMW R 2 and BMW R 4 .
There were at least two variants of engine cooling: a simple solution with a V-belt-driven, four-blade fan in front of the cylinder, which was only seen in the test vehicles, and a more elaborate version with a fan wheel on the front crankshaft stub and air baffles for guiding the cooling air, which are also described in the manuals and Spare parts lists has been described.
The rear wheel was driven via a three-speed gearbox with reverse gear and a cardan shaft .
chassis
The tricycle had a driven rear wheel and two steerable front wheels.
The rigid front axle was suspended from two longitudinally installed leaf spring packages.
The rear wheel was guided on a cast single- sided swing arm with a cantilever leaf spring, in the longitudinal spar of which the cardan shaft ran. The complex construction offered the following advantages:
- the rear wheel was easy to remove
- the disc wheels were interchangeable
- the flexible disk of the double ball-bearing cardan shaft was arranged exactly in the axis of rotation of the rocker arm
- the wheel guide was very rigid
- Compared to the usual chain drives, the cardan drive was maintenance-free and free of contamination, except for the oil change every 10,000 kilometers
BMW pursued this pioneering design principle again until 1980 in motorcycle under the name "Monolever" in the BMW R 80 G / S .
The foot brake pedal and the lockable handbrake lever acted on all three drum brakes via cables.
construction
In front of the rear wheel, the driver and front passenger sat on a car seat beneath which the standing single-cylinder engine was installed. For a surcharge there was a closed cabin with 2 doors for the driver and front passenger. In contrast to some other designs, the tricycle did not have a handlebar , but a steering wheel. A small flatbed (1600 mm × 900 mm) was set up above the front axle. There was a transport box with a front flap under the bed. The permissible total weight was 650 kg.

Competitor
- Goliath Rapid / Standard, years of construction 1926 to 1933
- Oscar Vidal & Sohn Tempo-Werk : Tempo T1 and T2, years of construction 1928 to 1930, a very similar load cart based on a motorcycle
- Deutsche Industriewerke D delivery van L 7 1927–1930
- Tatra 49 , 1929-1930
The competitors were on the market earlier and only offered the driver a motorcycle seat, which in some cases did not allow a passenger. At the end of the 1940s, Innocenti built the similarly divided Lambretta FA, FB and FC models until 1952
