The Ikarus 66 is a bus from the Hungarian bus manufacturer Ikarus . It was introduced in 1952 and produced from 1955 to 1973.
The Ikarus 66 was designed with a self-supporting structure as a line bus for local and regional transport , the Ikarus 55 was the almost identical variant and produced in the same period as a touring and intercity bus .
The drive unit was a water-cooled cyclone chamber - diesel engine with six cylinders of the type D-614 of the Hungarian producer Csepel with a displacement of 8275 cm 3 together with a manually switching, some synchronized five-speed gearbox is used. The engine delivers an output of 107 kW (145 hp) at 2300 rpm. It is arranged upright in the rear and drives the rear axle of the vehicle via a single-plate dry clutch , the transmission and an outer planetary gear . With this drive unit, the bus can reach a top speed of 61 to 98 km / h, depending on the gear ratio. The bus has steering assistance.
Leaf-sprung rigid axles with telescopic shock absorbers were used on the chassis . With an empty weight of 9.0 t, the permissible total weight is 15.0 t. The pneumatic brake acts on all wheels and has been supplemented by a mechanical parking brake .
The engine compartment is located behind the passenger compartment - protected by a partition wall with a window - and is accessible through two large folding doors in the rear that open wide on both sides. The body is simplified compared to the Ikarus 55 with a very similar external appearance. The Ikarus 66 has a four-part panoramic windshield with two large flat front windows and two slightly curved corner windows. Overall, the aerodynamic appearance corresponded to the ideas of the time . The roof edge glazing and the position lights in small fins on the roof of the Ikarus 66 were dispensed with from 1959, and the front was then given a real grill between the headlights.
The doors used were folding doors that were operated from the driver's seat. The bus was available with three doors (two three-wing doors at the front and rear and one four-wing central door) as a city bus and with two three-wing doors as an intercity bus , with the rear door either in front of or behind the rear axle. With this arrangement, the driver could take over the handling of the passengers in the regular service and dispensed with the conductors , which were still widespread at the time . The passenger area of the city bus offered 32 seats and 58 standing places.
The GDR imported the various versions of the Ikarus 66 from 1957. Together with the Ikarus 55, 8,350 vehicles were imported, of which 1451 Ikarus 66 still existed in September 1988. Because of the noticeable rear end and the somewhat gurgling, loud engine noise, these buses became popular in the GDR also called "rocket". Due to the long service required in the GDR, the vehicles of the 1960s and 70s received a "general overhaul" (basic overhaul) in the course of time, whereby they also received other engines in some cases, for example the Schönebecker 6-cylinder diesel engine 6 VD 14.5 / 12 SRW from the Nordhausen engine plant .
