  • the invention relates to the field of transport engineering, in particular, to the design of the front suspensions of wheels of a dependent pneumatic type for vehicles, namely: a bus.
  • a front suspension of the wheels of a bus comprising a front axle beam connected with a fixture for fixing the base of the body, two telescopic shock absorbers, a reaction rod and two air cylinders (see Bus LiAZ-5256 and its modifications. Operating Instructions, “Car Attributes”), M ., 2001, p. 247).
  • the device for fixing the base of the bus body is made in the form of a V-shaped frame, hinged to the front end on the body base, and in the middle part on the front axle beam. At the end opposite the hinge, a transverse beam-beam is attached to the frame, on which shock absorbers and air balloons are mounted, as well as a reaction rod, which fixes the position of the body from lateral displacements relative to the front axle beam.
  • a disadvantage of the design of the known front suspension of the bus is the inability to provide the necessary dynamic characteristics of the suspension when the bus is moving in turns, wheels bend to the road in the same direction and at the same angle as the body with its roll.
  • Another disadvantage of the known design of the front suspension is the complexity of the design, which complicates the process of its assembly, repair, and also increases its mass and reduces the layout space.
  • the closest technical solution to the declared The invention is a front suspension of the bus wheels, comprising a front axle beam, longitudinal rods, at the ends of which there are heads with through holes, a reaction rod, two telescopic shock absorbers and two air cylinders mounted on brackets (see Spare parts catalog, Ikarus bus (Ekarus) 280.33 Budapest, 1986).
  • a disadvantage of the known design of the front suspension of the bus wheels is the presence of three longitudinal rods and low reliability of the suspension, because the connection points of the heads with the longitudinal rods are prefabricated (by screw connection), which in the presence of vibration loads and torque arising from the movement of the bus leads to the destruction of the rods, for example, to tearing the head out of the rod.
  • An object of the invention is to increase the reliability of the suspension, as well as reducing its mass by simplifying the design.
  • the technical result of the invention is to reduce the height of the floor in the cabin of the bus relative to the roadway and improve the dynamic characteristics of the front suspension of the wheels of the bus.
  • each longitudinal rod is made in the form of a strip of constant rectangular section with a bend of one of its ends perpendicular to its longitudinal axis, and each head is made in the form of a cylinder with an open surface.
  • figure 1 shows the front suspension of the bus, General view
  • figure 2 shows the head, side view.
  • the front suspension of the wheels of the bus 1 (Fig. 1) contains a beam of the front axle 2, on which two brackets 3 are mounted to accommodate pneumatic cylinders 4, designed to spring the bus body and provide spring suspension properties due to the elasticity of compressed air.
  • telescopic shock absorbers 5 are attached, which are used to dampen the vibrations of the bus body that occur when it moves on rough roads or in the event of an interaction with an obstacle on the road, and two longitudinal rods 6.
  • the longitudinal rods 6 are made in the form of steel strips of rectangular cross section, constant along the entire length of the strips (see figure 2).
  • each of the longitudinal rods 6 there are heads 7 made in the form of identical cylinders with through holes and an open cylindrical surface (Fig. 2) for swiveling the suspension with the longitudinal beam of the body base frame.
  • the heads are made by twisting the ends of the strips into the cylinder and rotating them 90 degrees relative to the longitudinal axis 8 of the strip in a horizontal plane.
  • the longitudinal axis of each head 7 is perpendicular to the longitudinal axis of the rod.
  • Each longitudinal rod 6 has a bend 9 of its surfaces at the junction of the head 7 with its surface, while the curved surface of each rod is perpendicular to the longitudinal axis of the rod in the horizontal plane.
  • Longitudinal rods 6 fix the beam of the front axle 2 in the longitudinal direction, perceive vertical loads on the beam of the front axle 2 and transmit pushing, brake and lateral forces from wheels 1 on the bus body.
  • the presence of an open cylindrical surface at the heads 7, i.e. the presence of a gap 10 provides damping of longitudinal dynamic loads on the body with pushing and braking forces from the wheels 1 on the body, and the presence of bends 9 at the junction of the heads 7 with the longitudinal rods 6 creates a torsion effect.
  • the elastic deformation of the longitudinal rod 6, obtained by bending its end by 90 degrees creates a moment that counteracts the roll of the bus, and then helps to align the body.
  • the longitudinal rods 6, being stabilizers of the body position, improve the dynamic characteristics of the wheel suspension.
  • one end is fixed to the reaction rod 11, and the other end is connected to the frame of the body base and serves to fix the body from lateral displacement relative to the beam of the front axle 2.
  • the front suspension of the bus wheels works as follows.
  • the proposed design of the front suspension of the bus wheels allows to reduce the weight of the suspension by simplifying its design, namely: reducing the number of longitudinal rods, increasing the reliability of the suspension and improving its dynamic characteristics, as well as reducing the floor height in the passenger compartment of the bus relative to the roadway to 465 mm, which facilitates landing and disembarkation of passengers during the operation of the bus in urban conditions.
  • a bus using the proposed design of the front wheel suspension allows it to be assigned to the class of buses with a lower floor level, unlike buses that use the well-known wheel suspensions belonging to the class of high-floor buses.

Abstract

L'invention concerne l'industrie des transports et plus particulièrement la construction de suspensions avant de type pneumatique non indépendant pour des moyens de transport tels que l'autobus. L'invention permet d'augmenter la fiabilité de la suspension, de réduire sa masse par l'utilisation d'une suspension simplifiée et de réduire la hauteur du plancher dans l'habitacle de l'autobus par rapport à la chausse et d'améliorer les caractéristiques dynamiques de la suspension avant. Selon l'invention, la suspension avant de l'autobus comprend la poutre l'axe avant, des tiges longitudinales possédant à leurs extrémités des têtes avec des trous traversants, deux amortisseurs télescopiques, une barre de torsion et deux bouteilles pneumatiques montées sur des supports. En outre, la suspension comprend deux barres longitudinales, chaque barre longitudinale se présent comme une bande de section rectangulaire constante, avec une certaine courbure de chacune de ses extrémités orientée perpendiculaire par rapport à son axe longitudinal, chaque tête se présentant comme un cylindre à surface non close.
