Definitions

• the present invention finds its utility in activities relating to driving. It mainly aims to promote learning to drive motor vehicles in good safety conditions, by controlling skidding or loss of grip.
• the invention provides a skid simulator device characterized in that it essentially comprises a support stand provided with mounting means in at least one fixed position centered on the axis of a vehicle wheel, and a caster rotatably mounted at one end of a fork itself mounted by a pivot at its other freely pivotable end around a radius to said support, said fork being oriented at an angle to said radius.
• the fixed position of the support corresponds to a vertical position of said spoke and the caster then reaches the same horizontal level as a normal vehicle wheel in place of which the device is mounted.
• this device in the direction of simulating a skid at low speed is easily understood by the fact that the caster, preferably in a largely eccentric position, has a small dimension compared to that of normal wheels, with the tires. that equip them, and that its support on the ground offers a grip much less than that of these tires.
• Driving at very low speed is nevertheless possible thanks to the hunting angle provided by the biased orientation of the fork carrying the caster, by freely pivoting on its support to orient itself either longitudinally parallel to the vehicle in a straight line, or laterally as a function of the direction of movement of the vehicle in the turns.
• the invention aims in in addition to allowing, by a variation of this hunting angle, to regulate the speed of movement of the vehicle for which the device will simulate the skid.
• the device according to the invention advantageously comprises means for adjusting the hunting angle by varying said orientation at an angle of the fork carrying the caster, possibly directly relative to the radius defined by the fixed position of the stand. support.
• these means for adjusting the hunting angle are designed to operate by acting on the orientation of said radius relative to the vertical.
• These may in particular be circularly elongated lights which allow the passage of conventional bolts making it possible to screw the support stand on a wheel drum, in an orientation which can thus vary around the fixed position defined above.
• it further comprises a protective housing mountable in said fixed position on a wheel drum centered on the axis.
• the stand can then also be mounted on the same drum, over a bottom of the housing which has holes for the passage of conventional bolts.
• the action of these bolts, which are part of the mounting means of the stand, can advantageously be supplemented by members preventing an untimely rotation of the drum, in particular by a lug fixed to the rear of the housing, intended to come in stop on a non-rotating element of the vehicle, such as a suspension element, this at least in the forward direction.
• the housing is shaped to wrap the stand and externally present a space similar to that of a wheel, as well as possibly an appearance similar to that of such a wheel provided with its tire.
• This same housing is advantageously open above the caster to allow free pivoting of the latter with the fork which carries it. It may include, at the level of the caster, a flexible skirt capable of hiding this equipment from view and of playing the role of a broom avoiding splashing.
• the stand comprises a connecting flange with the wheel drum in front of the latter and lateral reinforcement brackets placed on either side and on the other side of the drum, the assembly being completed by a perpendicular support plate which passes under the drum and supports the pivot at this location, in a position inside the support polygon of the vehicle.
• FIG. 1 shows in vertical section a skid simulator according to the invention, mounted on a wheel drum;
• FIG. 2 shows the same device seen in cross section from the right of Figure 1;
• - Figure 3 shows only the stand of the skid simulator, perspective view;
• the skid simulator is mounted on a wheel drum 2, at the end of an axle 3 which defines the axis of the device. It comprises a housing 4 which envelops a crutch 5, which supports in its lower part a caster 6 placed outside the housing proper, slightly under the drum 2.
• the housing 4 like the crutch 5 are mounted centered on the axis of the wheel drum, where the stand is linked to the housing by a crimping flange 10 formed by a bottom 7 of the housing, placed directly in front of the drum 2.
• the bottom 7 of the housing shaped to bypass the drum 2 all around, has in its upper part two legs 8 and 9. These are provided to come into abutment on elements of the suspension of the wheel set on which the simulator is mounted, one when the vehicle is traveling in forward, the other when it is traveling in reverse. They thus form an obstacle to any effect of rotation of the drum which would cause the unraveling simulator.
• the housing 4 has on its front face 11 a removable cover 12. This closes an opening 13, of square outline in the particular case described, which allows access easily to the entire system of mounting the skid simulator on the wheel drum. When the housing is closed, the cover 12 engages by lugs 14 under a flange 15 formed on the front face of the housing around the opening 13 and it is fixed in this position by a locking bolt 16.
• the stand 5 has a flat flange 18, which when the stand is in the mounted position on the wheel drum 2, is placed vertically in front of it, from which it is simply separated by the bottom of the housing 4.
• the stand 5 is reinforced by brackets, some 21.22 towards the rear of the device (towards the interior of the vehicle), others 23.24 towards the front. They join the flange 18 to a perpendicular plate 25, horizontal in the position shown.
• the plate 25 forms the support part on which is mounted a fork 26 which carries the caster 6 by a pivot 27.
• this pivot is located at the upper end on a plate connecting the two branches of the fork, then that the caster is rotatably mounted on its axis between the two branches of the fork at its lower end.
• the pivot 27 has its axis oriented vertically, on the radius of the stand virtually drawn between it and the center of the flange 18, therefore the axis of the axle.
• the fork 26 is oriented at an angle relative to this vertical radius. When it rotates, it therefore describes wine cone centered on this radius.
• the flange 18 has a square shape and that the housing 4 which envelops the stand has a circular shape, however truncated at its lower part at the level of the roller 6.
• the shape of this housing up to its outer contour 31 occupies a space corresponding substantially to that of a normal vehicle wheel fitted with its tire.
• the housing 4 is closed by a transverse wall connecting the bottom and front face over its entire circular outline, while it is open at its lower part, truncated to allow passage to the caster 6 in all the positions it takes during the pivoting of the fork 26.
• a skirt 32 of flexible material which constitutes both a concealment for the caster and its fork and wine mop anti-mud when the simulator skid is in operation, the caster 6 bearing on the ground.
• the distance between the caster and the axle axis provided by the biased orientation of the fork 26 defines the caster angle which determines the speed at which the vehicle thus equipped tends to slip. .
• This hunting angle is adjustable by the method of mounting the skid simulator on the wheel drum 2, depending on whether the radius of the pivot 27 is more or less inclined in one direction or the other relative to the truly vertical direction.
• slots 34 are formed through the flange 18 in correspondence with orifices 35 in the bottom of the housing 4, which themselves correspond to tapped holes in the wheel drum which serve as conventional way of fixing the wheel by bolts not shown.
• the bolts are screwed through the lights 34 and the holes 35. Their tightening blocks the flange 18 against the bottom of the housing in any of the positions authorized by the lights.
• Figure 2 shows that the flange 18 has an additional light 36, in which then moves the pin 37 protruding from the housing.
• the position of the stud 37 in the slot 36 makes it easy to identify in what position the crutch is located relative to the reference position where the pivot 27 is vertical to the axle axis.
