Abstract
In a rotary piston engine in trochoidal design with a rotor housing, made of light metal, and with side parts, which are made of light metal, it is provided that the bearing bodies are connected in an area, in which the maximum gas pressures develop, by means of tie rods, which are oriented radially in relation to the bearing body, to a support element, which rests externally on the side parts and the rotor housing.
Claims21
A rotary piston engine in trochoidal design comprising:
- a light metal rotor housing;
- at least one light metal side part;
- an eccentric shaft;
- a bearing body that is disposed in the side part for receiving the eccentric shaft, the bearing body having an area of maximum gas pressure;
- at least one tie rod holding the bearing body's area of maximum gas pressure, the tie rod being oriented approximately radially in relation to the bearing body;
- and
- a support element resting on the side part and the rotor housing and being connected to each tie rod.
A method of making a rotary piston engine in trochoidal design, the engine including a light metal rotor housing, at least one light metal side part, an eccentric shaft and a bearing body that is disposed in the side part for receiving the eccentric shaft, the bearing body having an area of maximum gas pressure, the method comprising:
- using at least one tie rod to hold the bearing body's area of maximum gas pressure;
- orienting the tie rod approximately radially in relation to the bearing body;
- and
- connecting a support element, which rests on radially external surfaces of the side part and rotor housing, to the tie rod.
