Definitions

  • the invention relates to the field of transport engineering and is intended for use mainly in three-wheeled and four-wheeled vehicles (tricycles, ATVs, cars).
  • a vehicle suspension is a set of parts providing an elastic connection between the body (frame) and its wheels, reducing dynamic loads on the body and wheels, and damping their vibrations, as well as adjusting the position of the body during movement and in a static state.
  • the suspension as an intermediate link between the vehicle body and the road, must provide maximum traffic safety (to prevent the vehicle from tipping over, that is, have sufficient stability), patency (the ability to overcome various obstacles) and smoothness, which determines ride comfort.
  • Known rear independent suspension of the wheels of the vehicle which is used in the tricycle CLEVER (Compact Low Emission Vehicle for Urban Transport), which was developed by a group of German scientists of the Technological University of Berlin.
  • CLEVER Cosmetic Low Emission Vehicle for Urban Transport
  • Known tricycle suspension one front and two rear wheels provides for tilting the body movement of the rear wheels along the body on the trailing arms up and down. The tilt of the hull to overcome steep turns, the raising of the wheels when hitting obstacles on the road and the fixing of the wheels at stops is carried out using hydraulic drives controlled by automation.
  • the well-known independent rear suspension of the wheels of the vehicle provides an elastic connection of the CLEVER tricycle body with axles and wheels, a fairly smooth ride and stability, but is technically loaded with automation and hydraulics and, in this regard, is expensive and bulky, that is, not compact.
  • the well-known independent rear suspension of the vehicle wheels has two trailing arms with wheels, which are equipped with shock absorber struts assembly with springs.
  • the levers are pivotally connected to the lower part of the body, and on the other, to the upper part of the body through pivotally mounted strut assemblies with springs and an equal-arms rocker, which is pivotally mounted on the upper part of the body at a point located on its central longitudinal axis.
  • the design determines the simultaneous relationship of the wheels with each other, as well as between the wheels and the vehicle body, which ensures vertical wheel travel, which is necessary to overcome significant obstacles in the vertical position of the vehicle body relative to the horizon of the road surface.
  • the vehicle is thus amortized by the operation of the strut assemblies with springs attached to the beam, which in turn is attached to the body with a hinge.
  • levers or rocker arms can be fixed to the body.
  • the well-known independent rear suspension of the wheels of the vehicle has two longitudinal arms with wheels connected by cylindrical joints to the lower part of the body and ball joints through racks with ends of an equal-arm rocker arm, between which a central longitudinal arm is mounted on one transverse axis to which an equal-arm rocker of its central arm is pivotally attached part, connected on the one hand with a cylindrical hinge to the lower part of the housing, and on the other hand, through a spring-shock mechanisms still with an upper part of the housing.
  • the shock-absorbing spring mechanism of the known device is represented by two shock absorbers assembly with springs.
  • Ensuring smooth running of the vehicle is based on the conversion of impact energy when hitting bumps in the movement of the elastic element of the suspension, as a result of which the impact force that is transmitted to the body decreases and the ride increases.
  • the design of the well-known rear independent suspension of the vehicle wheels allows the middle lever to absorb and cushion the impacts from the levers with wheels, while at the same time allowing each lever to move up and down relative to the body, allowing the vehicle to tilt when driving on uneven surfaces and in corners.
  • the levers When driving in a straight line or in parking lots in the event of a possible fixation or blocking of all three levers together, the levers will work as a single pendulum lever, which absorbs and softens the impact of the wheels and does not allow the body to tilt to the sides, while maintaining the stability of the vehicle, which will allow it to reliably move straight at low speeds.
  • the design of the known suspension which is due to the presence of a large number of elements and their location, occupies a fairly large space. This reduces the working space of the vehicle, which is a disadvantage.
  • the known suspension provides sufficient reliability of the vehicle by achieving a smooth movement of the vehicle with the possibility of increasing its stability, but is structurally made with many elements and the connections between them and is not compact.
  • the basis of the invention is the task of creating a rear independent suspension of the wheels of the vehicle, in which by introducing new elements, a new version of the elements and new connections between the elements provides the rigidity of the vehicle (structural stability without vibrations of the body) when moving in a straight and static state with a vertical position hulls, smooth running without vibrations (elastic connection between the wheels of the vehicle and its body) while achieving a compact suspension design and the whole vehicle with a decrease in the number of elements and connections, which increases the comfort and reliability of the vehicle when using it.

Abstract

L'invention se rapporte à une suspension de roues d'un moyen de transport. La suspension arrière indépendante de roues d'un moyen de transport comprend deux leviers longitudinaux et un mécanisme de blocage de tous les leviers entre eux. Les leviers sont connectés par des charnières cylindriques à la partie inférieure de la carrosserie, et par des charnières à billes aux extrémités d'un arbre à cames à épaulements égaux. Sur l'axe transversal se trouve un levier longitudinal central auquel vient se fixer de manière articulée l'arbre à cames à épaulements égaux au niveau de sa partie centrale. Le levier longitudinal est connecté par une charnière cylindrique à la partie inférieure de la carrosserie et par un mécanisme amortisseur à ressort à la partie supérieure de la carrosserie. Le mécanisme de blocage comprend des éléments de fixation connectés aux leviers. Sur les parties latérales de l'arbre à cames à épaulements égaux se trouve au moins un élément en forme de charnière cylindrique divisant les parties latérales de l'arbre à cames en segments de manière à pouvoir modifier leur position angulaire les uns par rapport aux autres, ainsi que des éléments d'extrémité télescopiques. Il est ainsi possible d'augmenter la stabilité et la douceur de la conduite.
