Definitions

  • This invention relates generally to the automotive industry and, more particularly - to the unique control features of a three-wheeled vehicle.
  • the characteristics of tilting three-wheeled vehicles combines the maneuverability of a motorcycle and the stability and safety of an all-terrain vehicle (ATV), also known as a quadricycle.
  • ATV all-terrain vehicle
  • the change of driving direction for such vehicles is initiated by turning the front wheels and the stability— by tilting the vehicle body and front wheels to either one or the other sides to compensate the centrifugal forces.
  • the tilting itself can be usually controlled by the body of the driver, by additional tilting mechanisms, by using hands or legs of the driver or by using other interactive systems. Examples of such technical solutions are stated below.
  • the chassis of a tilting three-wheeled vehicle can be either a solid frame or a combined frame consisting of two parts— front and back.
  • the front frame part has a two- wheel suspension and the steering unit, the back frame part— rear suspension with a wheel, motor, and the vehicle body.
  • Vehicles with a solid frame that feature a non-tilting front suspension and the body are described in patents— US2017144719, WO2018211973.
  • Vehicles with a solid frame that feature a tilting front suspension and the body are described in patents WO2017194686, WO2017062996.
  • Further analysis consists of three- wheeled vehicles that feature a combined frame, consisting of two interconnected parts— front and back, with a symmetrical wheel configuration— two in the front and one in the back.
  • Analyzed three-wheeled vehicle which has an interactive control system, featuring actuators, various sensors, electrical, mechanical, pneumatic, and hydraulic controllers, described in patent No. US2018334213.
  • Such a vehicle is equal to the four-wheeled vehicle by its characteristics and is technically very complex as well as relatively expensive to manufacture.
  • the invention suggests a type of tilting vehicle control where the direction of the vehicle is initiated by the steering wheel and the tilt of the vehicle is controlled by tilting the same steering wheel shaft to the left or the right from neutral (center) position by the driver. The distance from the driver and the steering wheel does not change during the tilting process as the whole vehicle body is tilting.
  • Such tilting three-wheeled vehicle has a back frame part featuring a motor, single drive wheel, driver and/or passenger seats, and the vehicle body.
  • Two symmetrical and independent suspensions, featuring four“V” shape arms are connected to the front frame part via hinge joints.
  • the bearings at the tips of the top and bottom arms are connected to the wheel axles, shock absorbers, and the control unit by hinge joints as well.
  • the shock absorbers are mounted between the tip of the bottom arm and the underframe via hinge joints.
  • the control unit consists of two parts - the steering unit and the tilting unit which are interconnected via steering shaft, mounted in the steering shaft longitudinal bushing.
  • the steering unit features the mechanical parts, placed between the steering shaft and the wheel knuckles, dedicated to changing the direction of the vehicle in motion.
  • the tilting unit consists of a lever that is connected to the front part of the frame, underframe, and the steering shaft longitudinal bushing in three points.
  • Steering unit features mechanical parts connected to the steering shaft - universal joint, bevel gear, and the tie rods, which are connected to the wheel knuckle and the steering arm using the hedge joints.
  • one axle could be flexible, connected to the steering arm via a hinge, and another one - stationary.
  • Flexible axle should be mounted on the linear bearing outside part and the stationary axis should be inserted into the linear bearing whose axis at a 90-degree angle is mounted into the bearing of the underframe.
  • the element pairs of the body leaning system - frame axle and the bearing of the lever, moving axle and the linear bearing outside part, linear bearing axis, and the bearings of the underframe can be switched between without changing the general joint function.

  • Frame 1 is connected to the underframe 2 by frame axles 5 and 6.
  • independent front suspension 3 has two symmetric assemblies - left and right.
  • the left suspension assembly consists of two“V” shape (also known as the triangle) arms— top arm - 7, bottom arm - 8, as well as the wheel knuckle 9 with the wheel axle 10 and the shock absorber 11.
  • the tips of the arms 7 and 8 are connected to the frame 1 with hinges.
  • the tip of the top arm 7 is connected to the top of the frame 1 and the tip of the bottom lever 8 is connected to the bottom of the frame 1.
  • the shock absorber 11 is connected to the narrow side of the bottom arm 8 by one end, and connected to the underframe 2 by the other end using hinge joints.
  • the right suspension assembly consists of the top arm 7a and the bottom arm 8a, the wheel knuckle 9a with the wheel axle 10a and the shock absorber 11a.
  • the connections between right suspension assembly parts are analogical to the connections between left suspension assembly parts.
  • the control unit 4 consists of the steering unit 4a and the tilting unit 4b.
  • Steering unit 4a features the steering wheel 12, steering shaft 13 which is mounted into the steering shaft longitudinal bushing 14 (which is also a part of the tilting unit 4b), universal joint 15, bevel gear 16, steering arm 17 and the tie rods 18 and 18a.
  • Tie rod 18 is connected to the wheel knuckle 9 and the tie rod 18a is connected to the wheel knuckle 9a.

  • Fig. 3 and fig. 4 is the representation of a real-world working example.
  • the twist is transferred to the steering arm 17 through the universal joint 15 and the bevel gear 16. Then the twist is transferred through the tie rods 18 and 18a, eventually steering the wheel knuckle 9 and 9a with the wheel axles 10 and 10a to either one or another side.
  • the movement is transferred to the frame 1 through the steering shaft longitudinal bushing 14 and the lever 19 eventually tilting the body of the vehicle to the corresponding sides. Due to the two arms in the front suspension, when the steering wheel is being steered and the body is being tilted, the front wheels are tilting synchronically with the body.
  • the tilting of this vehicle body including the frame and the seats, and the steering of the front wheels are two separate actions, both of which are performed by the same steering wheel and the steering shaft. Both of these actions can be performed separately.
  • the standing still vehicle can be tilted without steering the wheels and vice versa - the vehicle can have front wheels steered without tilting the body.
  • Such type of vehicle control can be used in relatively heavy vehicles.
  • Such type of a three-wheeled vehicle control gives the driver additional maneuverability capabilities.
  • the tilting angle is always fully controlled by the driver depending on the speed of the vehicle, angle of the turn, and the road surface - such a system provides a pure natural feeling for the driver. Depending on the purpose of the vehicle, the tilting angle can be adjusted.
  • the invention is mechanically not complex, meaning that it can be easily implemented in various mass and size three-wheeled vehicles. Such a solution can be implemented in specific all-terrain vehicles featuring four wheels and independent rear suspension as well.

La présente invention concerne, de manière générale, l'industrie automobile et, plus particulièrement, les éléments de commande uniques d'un véhicule à trois roues. La présente invention concerne un type de commande de véhicule inclinable où la direction du véhicule est générée par le volant et l'inclinaison du véhicule est commandée en inclinant le même arbre de volant vers la gauche ou vers la droite à partir de la position neutre (centrale). Le véhicule à trois roues inclinable est constitué du cadre (1), qui a un moteur, des sièges, d'une seule roue d'entraînement, et de la carrosserie du véhicule à l'arrière, et de la suspension symétrique indépendante à deux roues (3) avec une unité de commande (4) dans la partie avant du cadre. La solution est unique de par son sous-châssis (2) monté sur les essieux (5, 6) du cadre (1) ainsi que l'unité de commande (4) qui est constituée de deux unités distinctes - l'unité de direction (4a) et l'unité d'inclinaison (4b), toutes deux étant raccordées par le volant (12) et l'arbre de direction (13) qui est monté dans la douille longitudinale d'arbre de direction (14). L'unité de direction (4a) comprend des pièces mécaniques pour la direction de véhicule qui sont raccordées entre l'arbre de direction (13) et les rotules de roue (9, 9a). L'unité d'inclinaison (4b) comprend le levier (19) raccordé au cadre (1), au sous-châssis (2) et à la douille longitudinale d'arbre de direction (14). L'inclinaison de la carrosserie de véhicule, comprenant le cadre et les sièges, et la direction des roues avant sont deux actions distinctes, toutes deux étant effectuées par le même volant et l'arbre de direction. Ces deux actions peuvent être effectuées séparément.
