Definitions
- the invention relates to a built piston with a forged upper part made of steel and a lower part made of an iron material according to the preamble of claim 1 or a piston made of iron material consisting of at least two components which are connected by welding or soldering technology.
- a piston is known from DE 3032671 A, in which the upper piston part is made of heat-resistant steel and the lower piston part is made of extruded steel and in which the upper piston part and the lower piston part are connected to one another by welding or soldering, but which has remained papery state of the art.
- the invention is therefore concerned with the problem of producing forged steel parts or pistons with a sufficiently long shaft in a simple manner.
- Friction welding and MAG welding are particularly suitable as welding methods for connecting the shaft extension to the forged piston or lower part.
- the shrinking or shrinking is usually carried out by heating or cooling at least one of the components to be connected.
- Fig. 1 shows a piston according to the invention in cross section, cut left in the pin direction, cut right in the pressure-counter pressure direction
- Fig. 2 shows a piston according to the invention with a shrunk shaft extension.
- a built piston 1 consists of an upper part 2 made of forged steel and a lower part 3, which are connected by expansion screws 4.
- the lower part 3 consists of a forged component 6 made of steel with hubs 7 and an approximately tubular shaft extension 5 connected to the component 6 by welding, consisting of an iron material.
- the latter has a collar 8 which can be machined for the purpose of setting a piston weight that is within the tolerance range.
