Anti-roll and suspension system for radio controlled car

Abstract

The invention relates to the utilization of magnetism in the roll stabilization and suspension of a radio-controlled car. In small radio-controlled vehicles, in particular, it is difficult to implement the conventional mechanical roll stabilization and a well-functioning suspension due to the small size, the accuracy required, dirt, and the loads exerted on the structures. In the structure according to the invention, the roll stabilization and suspension are implemented by means of magnetism, according to FIG. 2. The magnets at the ends of supporting arms (6) attract each other, implementing the roll stabilization. Magnets (3) are installed under the supporting arm magnets, repelling them and providing suspension.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) In the following, the invention is shown in more detail with reference to the appended drawings, in which:

(2) FIG. 1 shows a conventional front suspension solution, whereto the roll stabilization implemented by magnets is added.

(3) FIG. 2 shows the combined roll stabilization and suspension, which is implemented by magnets.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

(4) FIG. 1 shows the front suspension solution that is generally used by the hobbyists, excluding the magnets (1), which are shown in the figure and which implement the roll stabilization according to the invention. The magnets (1), according to the invention, are placed at the ends of the supporting arms (6) that are used in the suspension, so that they attract each other. The supporting arms now follow each other without locking into each other, and the roll stabilization is implemented. The solution can be applied to front and rear axles. In FIG. 1, the suspension is implemented by means of solutions that are generally used, mechanical springs (2). However, a magnetic suspension can be combined with the magnetic roll stabilization, according to FIG. 2. In that case, magnets (3) are placed below the stabilizer magnets (1), so that they repel the stabilizer magnets (1). In this way, a progressive suspension that is provided with roll stabilization is achieved, which has a fairly simple structure and which offers a number of adjustment possibilities. The number of adjustment possibilities can be increased by adding, above the stabilizer magnets (1), a magnet (4) that is attached to the body and that repels the stabilizer magnets (1). In the following, there are adjustment possibilities of the roll stabilization and suspension arrangement that is implemented in this way:

(5) The intensity of the roll stabilization can be adjusted by adjusting the distance between the magnets (1), the intensity, and the shape of the magnets or the direction of the magnetic flux.

(6) The strength of the suspension can be adjusted by adjusting the intensity and the location of the magnets (3) or the direction of the magnetic flux. In the test version according to FIG. 2, this is implemented by stacking several superimposed magnets to constitute the magnet (3), whereby the adjustment is simply carried out by changing the number of superimposed magnets.

(7) The response, progression and ground clearance of the suspension can be adjusted by adjusting the intensity, shape or distance of the magnet (4) from the stabilizer magnets (1). In the test version according to FIG. 2, this is implemented by a flexible piece of fibreglass, which is attached to the body and the stiffness of which can be adjusted by a screw (5).

(8) NB. The magnetic polarities shown in FIGS. 1 and 2 and the positions of the magnetic poles are suggestive, with a purpose of presenting the operating principle.
