Definitions

  • the invention belongs to a road transport axle
  • the widely used car train semi-trailer has a fixed wheel rolling plane.
  • the semi-trailer wheels are relatively laterally slipped relative to the road surface.
  • the driving resistance of the train is increased, the fuel consumption is increased, and the wear of the semi-trailer tires and the road surface is intensified. This is inconsistent with the current theme of energy-saving emission reduction and low-carbon life.
  • the sector bevel gear Z1 is fixed on the traction seat plate, and the first bevel gear Z2 is splined to the first transmission shaft (B), which can slide on the first transmission shaft (B) and Positioned at the position of meshing and disengaging with the sector bevel gear (Z1), the other end of the first transmission shaft (B) is equipped with a second bevel gear (Z3), which is mounted on the second transmission shaft (C)
  • the three bevel gears (Z4) are engaged, and the drive shaft (D) is also mounted on the second transmission shaft (C) to form a drive system;
  • the drive arm (D) is connected to the swing arm (c) via the first pull rod (b), and is driven.
  • the second pull rod (a) drives the steering tie rod to steer the steering wheel mounted on the steering axle of the semi-trailer to form a steering rod system; and an axle equipped with the steering wheel.
  • the invention adopts a forced change of the rolling plane of the semi-trailer wheel, so that all the wheels of the semi-trailer are moved around the center of rotation of the car train (as shown in Fig. 1). Achieve reduced lateral slip, reduced fuel consumption, and reduced tire and road wear.
  • Figure 1 is a simplified diagram of the car train movement based on the CA4226P2K2 tractor and the ZQZ9310TJZP trailer.
  • the original two-axle semi-trailer was changed to three-axle.
  • the angle a in the figure is the angle between the longitudinal axis of the tractor and the longitudinal axis of the semi-trailer.
  • the angle ⁇ is the angle of rotation of the steered wheel of the semi-trailer (the values of the two wheel angles on the same axis are different).
  • Figure 2 (a) is a schematic diagram of the drive of the drive system.
  • the axis ⁇ is the center line connecting the traction pin and the traction seat cleat.
  • the sector bevel gear Z1 is fixed on the traction plate and its center line coincides with the axis A.
  • the other end of the B-axis is equipped with a bevel gear Z3 which meshes with a conical pinion Z4 mounted on the C-axis.
  • a drive arm D is also mounted on the C-axis, which is connected to the steering rod system.
  • the bevel gear Z4 is simultaneously meshed with the cone wheel Z5, and the Z5 is connected to the pneumatic (or hydraulic) motor M to form an adjustment device for adjusting the tractor. After the initial engagement with the semi-trailer, the semi-trailer is turned to the state of the wheel.

  • the change of the rolling plane of the semi-trailer is caused by the change of the angle a (see Figure 1) between the tractor and the longitudinal axis of the semi-trailer as the car train changes, and the steering system is driven by the drive system shown in Figure 2a (see figure 2b).
  • the drive system consists of a fan-shaped bevel gear Z1 fixed on the support plate of the traction seat, a bevel gear Z2 mounted on the semi-trailer, a drive shaft B, a bevel gear Z4 and a drive arm D mounted on the same shaft as the Z4.
  • the train changes direction of travel ⁇ , Z1 drives Z2, Z2 drives Z3 via drive shaft B, Z3 drives Z4 and drive arm D mounted on shaft C.
  • the D-driven steering rod causes the wheel to change the rolling plane, making a circular motion around the instantaneous center of the car train 0 (see Figure 1).
  • the state of the initial connection of the tractor and the semi-trailer of the automobile train is uncertain, and the longitudinal axis thereof may be in a straight line or may intersect.
  • the angle ⁇ of the semi-trailer steering wheel must be adjusted during the connection (see Fig. 1) to match the angle ⁇ of the tractor and the longitudinal axis of the semi-trailer. Otherwise, the movement of the semi-trailer steered wheels cannot be guaranteed.

Abstract

Une semi-remorque à roues susceptibles de changer de direction par contrainte dont le secteur denté (Z1) est fixé à demeure sur la plaque de traction, une première roue conique (Z2) étant reliée à l'arbre de transmission (B) par cannelure et pouvant coulisser sur l'arbre de transmission (B) tout étant placée respectivement en position d'engrenage et de libération par rapport au secteur denté (Z1). L'autre extrémité de l'arbre de transmission (B) présente une deuxième roue conique (Z3) qui s'engrène avec une troisième roue conique (Z4) montée sur un second arbre de transmission (C) sur lequel se trouve un bras de commande (D) formant un système de commande. Ce bras de commande (D) est relié à un bras oscillant (c) via une première bielle (b) et fait osciller une seconde bielle (a) porteuse d'une bielle de direction transversale de manière à faire changer de direction les roues de direction. Cette semi-remorque peut réduire les dérapages, la consommation de carburant et l'usure entre les pneus et la chaussée.
