Telescoping cylinder device and vehicle

摘要

A telescoping cylinder device including double-walled cylinders is disclosed. By way of a pressure medium, the cylinders are displaceable relative to each other by moving inside the space formed between the two walls. A central through hole extends axially through the cylinders and provide a passage for transmission. A vehicle including a plurality of telescoping cylinder devices is also disclosed.

主权项

1. A telescoping cylinder device, comprising
a first cylinder having a cylindrical inner wall, a cylindrical outer wall and a space between said inner and outer walls; a second cylinder having a cylindrical wall which is axially displaceable in said space in response to a pressure exerted by a pressure medium; and a central through hole extending axially through said first and second cylinders and providing a passage for a transmission device, wherein the transmission device comprises a rotatable shaft extending axially in said through holes for transmitting a rotating motion to an object operatively connected to the rotatable shaft.
