The Jelcz 043 was a bus from the Polish commercial vehicle manufacturer Jelcz . It was produced from 1959 to 1986. The bus was the licensed version of the Czechoslovakian bus Škoda 706 RTO .

history

After the end of the Second World War, Poland urgently needed modern buses for urban and regional public transport . The only bus produced in Poland was the A81 Odra from Sanocka Fabryka Autobusów, developed on the basis of the A80 Bison truck . Despite positive test results of the bus, it was decided in 1957 to meet the further needs of the now nationalized transport industry in cooperation with the ČSSR .

On December 6, 1958, an agreement was signed between the Polish and Czechoslovak sides for the license production of the Škoda 706 RTO. Škoda delivered superstructures, chassis and equipment. In 1959, the first twenty buses delivered as CKD kits were assembled. The bus was named Jelcz 043. In the following year, production increased to 200 buses.

Although the Škoda 706 RTO MEX was manufactured under license as Jelcz 272 MEX from 1963 and the new Jelcz PR110IL intercity bus was produced from 1979 and its successor PR110D from 1984, production of the Jelcz 043 continued until 1986.

Between 1968 and 1970, the GDR imported the P-01 trailer and the Jelcz 021 articulated bus as well as Jelcz 043 buses. However, only around 350 vehicles were imported. Because of its similarity to the Škoda 706 RTO, which was imported in large numbers, the bus was mostly not perceived as a Polish product.

construction

The chassis of the bus consisted of a riveted ladder frame. The structure was formed by a subframe made of welded steel profiles on which the outer skin was riveted. The planking consisted of sheet steel. On the right side wall there were two 0.9 m wide conventional doors (as in a car, which were operated by hand and opened outwards), the rear one behind the rear axle. Because of the position of the engine, the front door could only be placed between the axles, which meant that the bus was only suitable for one-man operation to a limited extent. The driver's door was in the left side wall. The passenger compartment with a standing height of 1.9 m offered space for 42 seats and 10 additional folding seats . Since there was no underfloor luggage compartment, the luggage was stowed in luggage nets and shelves in the passenger compartment, and a roof rack was also available. The interior was lined with varnished pine panels, and the wooden floor was covered with rubber. In addition to the engine-dependent heater, there was also an auxiliary heater powered by diesel fuel.

The Škoda 706RT engine, also imported from the ČSSR, served as the drive. The engine, a six-cylinder diesel engine with direct injection , had a displacement of 11.78 l and an output of 160 hp (118 kW). The drive unit was completed by an unsynchronized five-speed gearbox. The engine sat in the chassis above the front axle. The rear axle was driven by a two-part cardan shaft. The chassis consisted of leaf-sprung rigid axles with telescopic shock absorbers . The bus was decelerated with pneumatically operated drum brakes on all wheels and an engine brake . The steering was a mechanical worm steering with pneumatic assistance. The tires (size 11.00-20) were mounted on Trilex rims . With a vehicle mass of 8700 kg, the permissible total mass was 12,680 kg.
