Abstract

An automatic device with electrohydraulic and/or electropneumatic driving, for reducing the effects of the centrifugal force onto cornering vehicles and thus limiting their skidding to the right, and that determines the transformation of the passage of the vehicles as on parabolic curves, following to a proportional raising of the vehicles platform on the external side of said curves, together with a suitable inclination of the axle of those wheels onthe same side.

Description

1
"AN AUTOMATIC DEVICE FOR THE REDUCTION OF THE CENTRIFUGAL FORCE EFFECTS ONTO CORNERING VEHICLES "
The present invention concerns an automatic device with electrohydraulic and/or electropenumatic driving, for reducing the effects of the centrifugal force onto cornering vehicles and thus limiting their skidding to the right.
It is known that said skidding effects are solved o n motor-cycles for races and not, and on bicycles by means of an inclination of the wheels, performed by the driver, towards the inside of the curves, so as to unload a considerable part of the centrifugal force onto the friction area of the tyres.
It is the aim of the present invention to transfer said efficacious movement condition also onto vehicles which until now have always had fix guiding of the wheels with respect to the frame, while for the solution of the mentioned need the wheels shall be inclined in the two ways according to the orientation of the curves.
The aim set forth is reached by means of the device according to the present invention which determines the transformation of the passage of the vehicles as on parabolic curves, following to a proportional raising of the vehicles platform on the external side of said curves, together with a suitable inclination of the axle of those wheels on the same side.
The advantage of the device according to the present inventio is evident: it allows to acquire greater safety at the same speed in curves and/or to face each curve at a higher speed in the sports field.
The present invention will be explained more in detail hereinbelow relating to the enclosed drawings in which an embodiment is shown.
Figure 1 shows an automatic device for reducing t he effects of the centrifugal force onto cornering vehicles, installed onto the back train of a vehicle V.
Figure 2 shows the device working, when the vehicle is cornering to the left.
Figure 3 shows a block scheme of the working principle of the device according to the present invention.
The enclosed figures show an automatic device for reducing the effects of the centrifugal force onto cornering vehicles, maily consisting of: - a centrifugal force tracer 1 , consisting of a cylindric body 2 inside which are provided a spheric counterbalance 3, free to move along the horizontal axis of the cylindric body, and two pressers 4 with recovery springs 5, and connected to pressure sensors 6;
- a plurality of moving pistons 7, which determine the inclination of the wheels' axle R;
- a pump 8 that introduces the fluid (liquid or gas) contained in a tank 9 into hydraulic shock absorbers A, determining the raising of the vehicles platform, and into said pistons 7 for the inclination of said wheels R;
- a control module 1 1 , incorporated or added to the electronic central C, and that can manage, according to the signals received by said tracer 1 , the pump 8 and the hydraulic valves 10, thus controlling the expansion liquid flow in said shock absorbers A and in said pistons 7.
The working of the device according to the present invention, relating to the mentioned elements, may be described as follows:
- in the very moment the vehicle V begins cornering, due to the centrifugal force the spheric counterbalance 3, contained in the cylindric body 2 of the centrifugal force tracer 1 , gets into contact with said presser 4 provided on the external side of the curvilinear trajec- tory of the vehicle, applying to said vehicle a pressure proportional to the centrifugal push exerted on the same;
- said pressure is taken by said sensor 6 connected to the presser stressed by said counterbalance 3, and the informations concerning said pressure are sent to the control module 1 1 contained in said electronic central C, and said module - according to the informations received - operates said pump 8 and the suitable hydraulic valve 1 0 so that the expansion fl u id, contained in said tank 9, flows to said hydraulic shock absorbers A and to the moving pistons 7 placed on the external side of the curve the vehicle V is cornering;
- the introduction of the fluid into said shock absorbers A determines the expansion of the same and the following raising, proportional to the centrifugal force taken, of the vehicle's V platform on the side external to the curve, so that the effects of the centrifugal force onto the vehicle are balanced by the disposition of the same, which is very similar to the one of a vehicle passing onto a parabolic curve; the expansion of said pistons 7, on the other hand, determines the inclination of the wheels R on the same side, giving the tyres a "motorcycle effect" that may further reduce the tendency of the vehicle of skidding towards the outward of the curve; - when the vehicle V comes out of the curve and said counterbalance seems not to be subject to centrifugal stresses, the recovery spring 5 of said presser 4 previously operated brings the latter back into its resting position, and the sensor 6 connected to the same sends signals relative to the lack of centrifugal stresses onto the vehicle to said control module 1 1 which provides, by means of said pump 8, for the outlet of the expansion liquid, led back to said tank 9, by said shock absorbers A and by said moving pistons 7, as well as for the closing of said hudraulic valve 10 previously used.
All this determines the horizontal levelling of the vehicle and the vertical levelling of the wheels, allowing said vehicle V to run on straight roads.
Furthermore, in consideration of the fact that the known mechanic suspensions consist of forks oscillating due to the effect of the range of one shock absorber and that, if the device according to the present invention is applied, by increasing said range an inclination is determined of the wheel opposite to the one on the curve, with a following considerable action of the horizontal piston, the present invention provides the possible presence of two further pistons (or of only one, if the suspension consists of one single axle), connected to the hydraulic or pneuma- tic system and applied to the connection points of the fork to the vehicles body, and that allow the suspension to come down parallel to the road and that keep the vertical disposition of the wheel that will be inclined at the same time in the correct manner by said horizontal piston.
