Definitions
- the present invention relates to a device for stabilizing a two-wheeled vehicle, in particular a scooter. It also relates to a two-wheeled vehicle equipped with this stabilization device.
- Document FR1249598 thus discloses a device for stabilizing crutches for a moped comprising a rod movable in rotation in a bearing located in the axis of rotation of the rear wheel of the moped, this rod ending in two crutch arms provided at their ends with rollers and being controlled by a control system including a lever bar, two links and a foot control.
- a stabilization device implementing a technique known as force feedback by which the driver feels the efforts reaction of the ground to which the crutches fitted with castors are actually subjected when they are in the low position. Thanks to the force feedback, the stabilization device can in a way measure and regulate the application forces of the crutches, which contributes to a significant increase in the comfort of use of this stabilization device.
- the stabilization devices proposed so far are complex to realize, because they use servo drives, controlled actuators, and relatively sophisticated control systems, which can lead to exorbitant costs, in particular for scooters of entry-level or mid-range.
- the object of the invention is to remedy this drawback by proposing a stabilization device for a two-wheeled vehicle, in particular a scooter, which provides the expected technical effects with simple and robust mechanical means.
- a device for stabilizing a two-wheeled vehicle such as a scooter, comprising:
- first and second retractable stand means arranged on either side of said vehicle, and each comprising a first and a second arm comprising at its end a caster,
- first and second crutch means Means for controlling by at least one foot of the pilot said first and second crutch means between a first state in which said first and second crutch means are retracted, and a second state in which said first and second crutch means are in stabilization contact with the ground, said first and second arms being mechanically connected and movable relative to an axis of rotation linked to the chassis of the vehicle.
- control means comprise lever means integral with at least one of the arms above said axis of rotation, these lever means being accessible by at least one foot of the driver from the footrest of said vehicle and arranged so that a pressure exerted forwards by at least one foot of the pilot on these lever means leads to the first state of retraction while a pressure exerted towards the rear by at least one foot of said pilot on said lever means leads to the second stabilization state.
- the pilot has, through the pressure he exerts towards the rear on the lever (s) ⁇ e controls when the side stands are in the low position, a real force feedback which gives it a pleasant and reassuring feeling and represents a concrete solution to the problem of pilot control of the stability of his vehicle at low speed.
- the particularly simple structure of the stabilization device according to the invention constitutes a radical solution to the recurring problem of weight and cost encountered in all the technical solutions proposed previously and which has hitherto constituted a prohibitive obstacle to their development.
- the number of parts and members required to produce the stabilization device according to the invention is significantly reduced compared to the stabilization devices of the prior art.
- the stabilization device according to the invention finds all its advantage in urban use with very short and repeated stops.
- the stabilization device according to the invention advantageously provides automatic scanning of this angle from the high position to the low position and vice versa.
- the angular scanning corresponding to the passage from the high position to the low position is carried out mainly by gravity, as soon as the pilot's feet cease to rest on the control means. There is then only a small pressure to exert to complete the angular scan.
- the lever means are connected at their ends by a control bar substantially parallel to the axis of rotation and actuable by the feet of the pilot, the stand arms being able to be connected mechanically or not by a piece axis of rotation or axial connecting bar.
- the two arms are arranged to be movable in rotation independently of one another around an axis of rotation linked to the chassis of the vehicle, and the first and second lever means are connected to their end to a common part acting as a torsion and bending bar.
- This variant embodiment provides differential control of the two crutches, the pilot being able to exert different pressure on each of the lever parts with each of his feet.
- the stand arms are then angularly offset. We can thus compensate for the transverse tilting effects of certain roadways.
- the first and second stand arms are mechanically connected by a part with an axis of rotation or an axial connecting bar movable angularly along the axis of rotation and a single right or left control lever is provided. extension of one of the stand arms.
- the stand means can be arranged so as to temporarily lift the chassis of the vehicle and its driver when passing first and second stand means from one state to another.
- the pilot of a scooter can obtain the positioning of crutches at low speed until the stopping of his vehicle which is lifted momentarily, which consequently eliminates the maneuver. difficult to put on center stand which was until now essential.
- the control means comprise first means acting as a pedal to place and maintain the first and second stand means in the retracted position, and second means acting as a pedal to place and maintain said means first and second stand means in the stabilization position, these first and second pedal means being fixedly attached to an axis of rotation to which the first and second stand means are connected.
- the respective arms of the first and second stand means may advantageously each include an elbow above the connecting axis, the arm parts located above said elbows being arranged to constitute lever control means actuable by the feet of the pilot. .
- the length between the contact end of each arm and the connecting axis is preferably adjustable according to various operating parameters such as the weight of the pilot, so that when the arms are in a substantially vertical position, the scooter chassis is substantially raised relative to its equilibrium position in which the stand means are retracted.
- the respective lengths of the left stand arm and the right stand arm can be chosen different, for example with a right stand arm 5 mm longer than the left stand arm, to allow for a transverse tilt. roadways in traffic areas on the right. It goes without saying that in left-hand traffic regions, a left crutch arm will be chosen slightly longer than the right crutch arm.
- first return means arranged between stand means and the chassis of the scooter so as to maintain said stand means in the retracted position after a retraction command exerted on the control means.
- second return means arranged between stand means and the chassis of the scooter so as to maintain said stand means in the stabilization position, after a stabilization action exerted on the control means.
- first and second return means can for example be made in the form of a spring with two positions fixed between the chassis of the scooter and one and / or the other of the stand means.
- a security option may include first means for locking the first and second stand means in the retracted position, as well as second means for locking the first and second means for stand in the low stabilization position, especially for "parking" mode.
- a two-wheeled vehicle equipped with a stabilization device comprising a chassis or frame adapted to receive an axis of rotation of two first and second arms belonging respectively to two first and second retractable stand means arranged on either side of said vehicle.
- This two-wheeled vehicle further comprises lever means integral with at least one of the arms above the axis of rotation, these lever means being accessible by at least one foot of the driver from the footrest of said vehicle and arranged so that a pressure exerted forward by at least one foot of the pilot on these lever means leads to a state of retraction while a pressure exerted rearward by at least one foot of said pilot on said leverage means leads to a state of stabilization.
- this vehicle is a moped provided with a fuel tank arranged along an element of the frame of this moped
- provision may be made for a particular configuration in which the axis of rotation of the stand arms passes through this tank.
- this axis is effectively materialized by a mechanical part with an axis of rotation, the reservoir must then have an appropriate structure and shape to allow the passage of this axis part.
- FIG. 1 schematically illustrates a scooter fitted with a stabilization device according to the invention, in three characteristic situations
- - Figure 2 illustrates a first embodiment of a stabilization device according to the invention
- FIG. 3 illustrates a second embodiment of a stabilization device according to the invention
- FIG. 4 illustrates a third embodiment of a stabilization device according to the invention
- FIG. 5 illustrates the variations in attitude of a scooter fitted with a stabilization device according to the invention, in a complete cycle of use.
- the stabilization device 1 installed on a scooter comprises on either side of the footrest of this scooter crutches 2 equipped with casters 3, mounted freely in rotation about an axis 4, and extended at their upper end by lever parts 5 connected by a control bar 6 extending, in the case of the scooter, above the footrest.
- the pilot's feet are supported on the control bar 6 so that the crutches 2 are in the raised or retracted position.
- the stabilization device 1 comprises two crutches 2A, 2B parallel provided at their lower ends with rollers 3A, 3B. These two crutches, made for example from tubes, dishes or profiles of alloy or steel, are connected on the one hand to an axial connecting bar 8 inserted for example in a support tube 7 secured to the chassis or the rest -foot of the scooter, and on the other hand to a control bar 6 by lever parts 5A, 5B bent relative to the main parts ⁇ es crutches 2A, 2B.
- the lever parts and the control bar can be produced from a single tubular part.
- the rigid mechanical structure constituted by the two crutches 2A, 2B, the axial connecting bar 8 and the control bar 6 is movable in rotation about the axis 4.
- the angled lever parts 5A, 5B of the stabilization device 10 are not connected integrally by a control bar, but comprise connecting parts 50A, 50B in sliding connection with a bar torsion 12.
- the lever arms 2A, 2B are arranged to be movable in rotation independently of one another about an axis of rotation 9 secured to the chassis of the scooter. This particular arrangement allows independent action on each of the crutches, in particular for taking account of irregularities in the ground.
- a single lever part 5C of the stabilization device 100 is provided as an extension of a stand arm 2B securely connected to the other stand arm 2A by a piece of axle rotation or axial connecting bar 8 movable in a connecting tube 7 fixed to the chassis.
- the force exerted by the pilot's foot on the lever part 5C is transmitted directly to the crutch arm thus extended and indirectly to the other crutch arm via the part of the axis of rotation or axial link bar .
- An important characteristic of the stabilization device according to the invention lies in the fact that its implementation has the effect of occasionally lifting the chassis of the scooter from its normal position of use. These situations of occasional lifting on the one hand allow to place a scooter on ⁇ es crutches much less effort than what is currently required from a pilot wishing to place his scooter on a center stand, and on the other hand provide the pilot with a real feeling of comfort at low speed before stopping and when stopping when he no longer has to put your feet on the ground to keep your balance.
- the chassis When the scooter is stopped in the absence of the driver, safety brake activated, the chassis is in the high stabilized position Hs, with reference to Figure 5, with crutches in the low position which can also be slightly inclined forward.
- a mechanism for locking the crutches in the stabilization position can optionally be activated.
- the scooter starts and the increase in its speed, combined with the friction of the surfaces of the rollers on the ground, has the effect of causing the crutches to rotate around the connecting axis and in particular the ironing of the crutches by the vertical position, this which has the effect of slightly lifting the chassis of the scooter and its passenger in a high attitude Hs.
- the tilting of the crutches then takes place and the pilot exerts by the sole weight of these feet a pressure forward on the control bar so that the crutches are completely retracted.
- the scooter trim Bc is at this stage minimal, due to the weight of the pilot who is fully supported without assistance from the crutches.
- the pilot releases the control bar, which makes it possible to lower the crutches by gravity, to enter contact of the rollers with the ground and tilting of the stabilization device.
- a pressure exerted backwards by the feet of the pilot on the control bar then causes the lifting of the chassis of the scooter with its passenger
- the stabilization device according to the invention can either be fitted to new scooters, or be installed on existing scooters.
