Definitions

  • the present invention relates to devices for tilt control of tricycle, reverse tricycle and four wheel vehicles. Specifically, the present invention relates to a mechanical device consisting of four pulleys and two flexible steel cables installed in a front or rear suspension, designed to be tiltable, which can be used in single-seater tandem or tandem vehicles and with chassis type tricycle, reverse tricycle or four wheels.
  • US 7, 487, 985 describes a mechanism that presents a three-wheeled vehicle, which offers maneuverability characteristics that are substantially similar to those of a two-wheeled vehicle, which does not require complex and / or control systems to operate effectively; said invention is based on a free tilt design, which does not present problems to achieve an inclination greater than 45 °, so that the driver is able to lean at any angle he requires, regardless of the speed or angle of the curve .
  • said invention is limited to reverse tricycle type motorcycles and for the device to work the driver requires using the upper body to tilt the vehicle and, as in a two-wheeled motorcycle, does not have a device that avoids lower your feet to the floor when the motorcycle is stopped, to correct an abrupt change of reverse moment and / or to tilt the vehicle at will while being stopped.
  • document US 6, 402, 174 describes a three-wheeled vehicle driven by pedals, with an inclined seat comprising two frames connected to each other perpendicularly by a pivot with a steering mechanism that allows the inclination of the body and of the wheels, independent of the turning radius.
  • said invention has the disadvantage of requiring to tilt the vehicle at all times to turn, since the wheels vary the direction of rotation according to the angle of the tilt mechanism, because the control rods are fixed in the suspension front so that it is only used as a support point to tilt the reverse tricycle, in other words, the tilting system in said document is NOT independent of direction, causing handling problems at low speeds, since that the driver requires tilting the tricycle to the maximum to make a simple U-turn or for a parking maneuver.
  • a further object of the present invention is also to provide a mechanical device for tilting a tricycle, reverse or four-wheeled vehicle, and of the single-seater or tandem type tandem type; which allows to use the entire weight of the body to tilt the vehicle, varying the center of gravity and avoid the need to lower the feet when stopped or when losing control due to an abrupt change in reverse movement, and when performing a bad maneuver when driving
  • Figure 1 refers to the device of the present invention placed in the front of a reverse tricycle type vehicle.
  • Figure 2 refers to the device of the present invention placed in the front of a vehicle with four wheels.
  • Figure 3 refers to the device of the present invention placed at the rear of a tricycle vehicle.
  • Figure 4 refers to the device of the present invention placed in the rear of a vehicle with four wheels.
  • Figure 5 refers to the device of the present invention placed at the rear of a vehicle and operated by a pair of rods.
  • Figure 6 refers to the device of the present invention placed at the rear of a vehicle and operated by a steering wheel.
  • the present invention relates to a mechanical device for the inclination control of a tandem or single-seater vehicle, and with a tricycle, reverse tricycle or four-wheel chassis.
  • the device consists of four pulleys attached to the vehicle chassis ( Figure 1), two of which are in an upright position (la and Ib), two in a horizontal position one on top of the other (2a and 2b).
  • Figure 1 a flexible steel cable (4a) is attached attached at one end to the lower suspension bar (3) of the vehicle and, in the another end to a bar or tube (5) that functions as pedals to operate the device and control the inclination to the left.
  • a flexible steel cable (4b) is attached attached at one end to the lower suspension bar (3) of the vehicle and the other end to the bar or tube (5), thus controlling the right inclination.
  • the flexible steel cable (4a) slides through the horizontal lower pulley (2a), then passes through the pulley attached to the side left (the) of the chassis in an upright position and finally it is held on the left side of the lower arm of the suspension (3) causing the vehicle to tilt to the left.
  • the flexible steel cable slides through the horizontal upper pulley (2b), subsequently, it passes through the vertical pulley held on the right side (Ib) of the chassis in an upright position and finally held on the right side of the lower arm (3) of the suspension causing the vehicle to tilt to the right.
  • To maintain a neutral position just simply keep the pedals balanced according to road conditions.
  • the device can be placed in the front of a four-wheeled vehicle ( Figure 2), in a tricycle or reverse tricycle vehicle (Figure 3), and in the rear of a four-wheeled vehicle ( Figure 4), as long as all wheels have a mechanism that tilts them at the same time.
  • the bar or tube (5) can be replaced by a pair of rods (6a and 6b) which are each placed in one end of the chassis and half of it; in this way the flexible steel cables (4a and 4b) connected to a bar (5a), are extended to said point with the help of two rigid braces (6a 'and 6b') connected to the pair of rods (6a and 6b) the which are attached to the chassis (6c) in order to pry and be able to pull or push the ends of the bar (5a) which in turn pulls the cables (4a or 4b) as required to achieve the inclination of the device with hands, in such a way that when pushing the cane (6a) and at the same time pulling the cane (6b) past the neutral point, the vehicle will lean to the left and when the cane is pulled (6a) and at the same time push the cane (6b) past the neutral point, the vehicle will lean to the right.
  • the bar or tube (5) can be replaced by a steering wheel (7), which has two fixed pulleys (7a 'and 7b') on the front one behind other which pull a pair of flexible steel cables (4a 'and 4b') when turning the steering wheel, however, so that the cables (4a 'and 4b') reach the wheel without problems, two pulleys are required ( 7a and 7b) with this it is achieved that the inclination device works correctly, therefore, when the steering wheel (7) is turned to the left passing the neutral point, the vehicle will lean to the left, when the steering wheel (7) is turn right and pass the neutral point, the vehicle tilts to the right, using your hands to turn the steering wheel.
  • the device object of the present invention allows the chassis and the three or four wheels of the vehicle to be tilted safely and at will; varying the angle of inclination according to the direction, radius of a curve and speed at which it is driven.

Abstract

La présente invention concerne un dispositif mécanique de commande de l'inclinaison de véhicules de type tricycle, tricycle inversé ou à quatre roues, qui permet d'incliner de manière sûre et à volonté le châssis et les trois ou quatre roues simultanément, en variant l'angle d'inclinaison en fonction de la direction, du rayon d'une courbe et de la vitesse de manœuvre. Ledit dispositif est constitué de deux câbles en acier flexible qui coulissent au moyen d'un ensemble de quatre poulies.
