发明名称 Energy transforming unit for distance measurement sensor
摘要 The subject invention relates to an air spring (1) with a distance measurement sensor (100), an energy transforming unit (200), a first mounting element (10) being adapted for being mounted to a first vehicle portion (2) and a second mounting element (20) being adapted for being mounted to a second vehicle portion (3). An air volume (50) is arranged between the first mounting element and the second mounting element. The energy transforming unit is adapted to transform a transition of the air spring from a first state (s1) of the air spring to a second state (s2) of the air spring into electrical energy and to provide the generated electrical energy to the distance measurement sensor. The energy transforming unit is arranged in the air volume (50) of the air spring.

主权项 1. An air spring, comprising: a distance measurement sensor; an energy transforming unit comprising a propeller and a generator; a first mounting element being adapted for being mounted to a first vehicle portion; a second mounting element being adapted for being mounted to a second vehicle portion; an air volume arranged between the first mounting element and the second mounting element, wherein the energy transforming unit is adapted to transform a transition of the air spring from a first state (s1) of the air spring to a second state (s2) of the air spring into electrical energy and to provide the generated electrical energy to the distance measurement sensor; wherein the propeller is adapted for being moved when transitioning from the first state to the second state and is adapted to drive the generator, wherein the generator generates the electrical energy; and wherein the distance measurement sensor is arranged within and receives the generated electrical energy within the air volume of the air spring; and a pneumatic pressure generator adapted for varying air pressure within the air spring, wherein the pneumatic pressure generator is positioned within the air volume of the air spring, and wherein the pneumatic pressure generator is adapted to modulate a pressure in the air volume when the generated electrical energy is below a threshold.
