Hydropneumatic system for controlling the tilting of two wheels of a vehicle and a vehicle equipped with said system

Abstract

The invention provides an intelligent hydropneumatic system for controlling the tilting of two wheels of a vehicle and a vehicle equipped with said system. An intelligent hydro-pneumatic system for controlling the tilting of two wheels of a vehicle, mechanically connected to the chassis of said vehicle by means of a first oscillating anchor arm (B1) and a second oscillating anchor arm (B2) respectively, the system including at least a first cylinder (10) and a second cylinder (20) suitable to be interposed between said chassis and said first oscillating anchor arm (B1) and said second oscillating anchor arm (B2) respectively, wherein said first (10) and second (20) cylinders include respectively a first chamber (101) and a second chamber (202) both with variable volume and containing a working fluid, wherein the transfer of said working fluid from said first chamber (101) to said second chamber (202) results in an increase in the volume of said second chamber (202) while the transfer of said working fluid from said second chamber (202) to said first chamber (101) results in an increase in the volume of said first chamber (101), and wherein said system comprises first connection means (23) which connect said first chamber (101) and said second chamber (202) so that said working fluid can be transferred alternately from said first chamber (101) to said second chamber (202) and from said second chamber (202) to said first chamber (101).

Description

technical field [0001] The invention relates to the field of vehicles with tilted wheels. In particular, the invention relates to motorcycles with at least two inclined wheels positioned, in particular, on the same horizontal axis. In more detail, the present invention relates to a device and / or system suitable for improving the leaning performance of a vehicle of the above-mentioned type, in particular a motorcycle. Even more specifically, the present invention relates to a device and / or system for intelligently controlling the inclination of at least two wheels in a vehicle and / or motorcycle of the above-mentioned type. Finally, the invention relates to a vehicle, in particular a motorcycle, with at least two tilting wheels equipped with a device or system of the above-mentioned type. Background technique [0002] Vehicles with sloping wheels are known in the art and are now widely disseminated and appreciated by users, wherein the expression "vehicle with sloping wheels...

AI Technical Summary

Problems solved by technology

[0007] The first problem or disadvantage is related to the fact that when the vehicle remains within the speed threshold that allows blocking and blocks the tilt system (i.e. when the tilt is blocked but the vehicle is still moving), the vehicle may hit holes or uneven places (unfortunately this often happens due to uneven road surfaces), but also possibly sewer covers or in any case a difference in height that causes the vehicle to become laterally unbalanced relative to the vertical (to the right or left respectively), while remaining tilt-locked until release speed is reached (in the case of an automatic locking device) or until the twistlock is released manually - usually via a button on the handle (in the case of a device that can manually activate or deactivate the blocking)

[0008] In these cases, there is a risk that, on restarting, with the consequent release of the tilt, the driver will encounter serious difficulties, as the vehicle, which is not perfectly vertical during the "recovery" phase of gradually increasing speed, tends to Falling sideways, in which, in order to counteract the imbalance, the driver is forced to intervene in the steering with a maneuver that inevitably leads to a change in trajectory, with the risk of a collision with other vehicles

[0009] Also, in general, another disadvantage is related to the fact that in uneven situations (pit, manhole cover, etc.), facing an obstacle with a vehicle with a locked tilt system can also cause the vehicle to tip over sideways, thus causing serious damage to the vehicle , the driver and any passengers, as well as persons or things nearby
