Rotary piston engine including a piston assembly, vehicle including the rotary piston engine and a manufacturing method for the piston assembly

摘要

A piston assembly is disclosed. In one aspect, the piston assembly includes a rotary piston, wherein the rotary piston comprises a first axis of rotation, a central bore having bore axis and at least two curved first constraint surfaces, and wherein the bore axis substantially corresponds to the first axis of rotation. The piston assembly also includes a substantially hollow-cylindrical bearing ring configured to be at least partially inserted in the central bore. The piston assembly further includes at least one fuse body configured to connect the rotary piston and the bearing ring, and to transmit, at least temporarily, a force in the two opposite axial directions relating to the first axis of rotation between the rotary piston and bearing ring.

1. A piston assembly, comprising:
a rotary piston, wherein the rotary piston comprises an axis of rotation, wherein the rotary piston defines a central bore having a bore axis and wherein the rotary piston includes at least two curved constraint surfaces, and wherein the bore axis substantially corresponds to the first axis of rotation, a hollow-cylindrical bearing ring configured to be at least partially inserted in the central bore, and at least one fuse body configured to connect the rotary piston and the hollow-cylindrical bearing ring, and to transmit opposing forces in opposite axial directions with respect to the axis of rotation of the rotary piston and the hollow-cylindrical bearing ring, wherein an elastic restoring force of the at least one fuse body generates a radial force with respect to the central bore.
