Abstract: A system for controlling tilting of two wheels of a vehicle, mechanically anchored to the chassis by a first and a second oscillating anchor arm is provided. The system has a first cylinder and a second cylinder suitable for being interposed between the chassis and the first and second oscillating anchor arms respectively. The first and second cylinders have respectively a first chamber and a second chamber with variable volume and containing a working fluid. Transfer of working fluid from the first to the second chamber results in an increase in the volume of the second chamber. Transfer of working fluid from the second to the first chamber results in an increase in the volume of the first chamber. A pipe connects the first and second chambers so that working fluid is alternately transferable from the first to the second chamber and from the second to the first chamber.
