Definitions

  • the purpose of present invention is to achieve a cost effective device for improving the traction of a vehicle at low speeds and under especially difficult driving conditions; conditions of a type that would normally prevent traction.
  • the friction device may be mounted on to vehicle equipped with studded tyres or winter tyres of the unstudded type.
  • studded tyres or winter tyres of the unstudded type may be replaced studs; the latter being used at all speeds relevant for transport in winter.
  • the present invention concerns a device that is cost-effective and performs the same function as snow chains, where the only difference is that they may be activated/deactivated from the drivers seat at low vehicle speed, such that the inconvenience of fitting on and removing the chains manually is avoided.
  • Figure 4 is a sketch of the friction element
  • the group marked as 110 may be controlled to travel along a track/path, typically forming a 45 degrees angle with respect to the road surface, as illustrated in figure 2, so that the belt 5 engages both the road surface and the tyre of the traction wheel 1.
  • the control system operates the friction device 110 to engage both the road surface and the tyre of the traction wheel, frictional forces will be transmitted from the traction wheel via the transmission device 11 , such as for instance a wheel, and the guide device 10, such as for instance a wheel, and belt/wire 5 so that the vehicle is exposed to a force in the same direction as the wheel is travelling/moving.
  • the friction element 110 may in principle be mounted in front of, or behind, the traction wheel 11 , the choice is likely to depend on the technical/geometrical limitations of a given vehicle. However it is essential that the friction element 110 is moved out of the path/track of the traction wheel in the deactivated condition so that splash flying off the tyre as seldom as possible hits the friction element.
  • a hydraulic actuator 8 is suspended in the chassis at point 7.
  • the actuator may also be elctromechanical or pneumatic, but it is preferred hydraulic in a preferred embodiment for a typical heavy vehicle.
  • the force with which the friction device is activated may be made adjustable from the panel. This may be performed by regulating/controlling the pressure in the cylinder. Equipment required to achive this function is commonplace and thus not described.

Abstract

Dispositif de frottement pour véhicules. Le dispositif de frottement est placé de manière à être en contact avec une roue (1) du véhicule, de préférence une roue de traction. Ce dispositif comprend au moins un dispositif de transmission (11), un dispositif de guidage (10) et au moins une courroie sans fin (5) qui présente des caractéristiques de frottement favorables. Le dispositif de transmission (11) est mis en contact avec la roue du véhicule (1) et la/les courroie(s) (5). Celle(s)-ci est/sont mise(s) en place autour du mécanisme de guidage (10), et est/sont en contact avec la surface sur laquelle roule la roue (1).
