  • the invention has the advantage, among other things, that, according to the applicable standards, strength values, road grip and driving properties of the anti-skid device can be maintained regardless of the system used, such as net chain, ropes or mechanical connecting bars. Furthermore, the solution according to the invention enables an uncompHzated and simple assembly of the anti-skid device. This can also be carried out by a technical layperson without great effort.
  • the anti-skid device according to the invention can be placed on the floor in front of or behind the vehicle wheel in question and then slowly run over with the vehicle wheel in the longitudinal direction. Functional self-assembly of the anti-skid device takes place, whereby it is tightened, clamped and fixed to the wheel circumference at the same time.
  • the journey can be continued with the anti-skid device according to the invention, for example a snow chain.
  • Another advantage of the invention is that it is possible to dismantle the anti-skid device with simple aids, such as a hammer, screwdriver or other simple striking tool.
  • the anti-skid device can be detached from the wheel outside of the wheel housing and then placed on the ground or the footprint during a rolling operation of the vehicle tire. The dismantling process is now complete and the chain can be stowed.
  • the clamping bracket can be rotatably connected to one another about an axis running essentially parallel to the longitudinal direction of the vehicle, so that the fixing device has an essentially W-shaped cross section.
  • the clamping bracket can be designed as an elastic curved bracket, wherein the clamping bracket can be concavely curved in an unmounted state with respect to the road.
  • the assembly and disassembly of the anti-skid device according to the invention can be further simplified in that the at least one clamping bracket is connected to at least one gripping bracket via at least one joint, the at least one joint is releasably fixable. For the purpose of disassembly, the joint can be released again and the fixing device opened.
  • the fixing devices can be connected to one another via connecting webs which bear against the running surface of the wheel in an assembled state.
  • the fixing devices can in this case be connected to one another via at least two strands which run parallel to one another and, in an assembled state, bear against the tread and / or the side flanks of the wheel.
  • the anti-skid device has a locking device arranged on a fixing device or connected to a fixing device with a rocker arm, by means of which sections of the at least one connecting element between the fixing devices can be fixed, the rocker arm in a locking position fixing the at least one connecting element can be fixable.

Abstract

L'invention concerne un dispositif anti-glissement (GVO) destiné à un véhicule, qui présente au moins deux dispositifs de fixation (FV1, FV2) destinés à un pneumatique de véhicule, lesquels peuvent être reliés l'un à l'autre par l'intermédiaire d'au moins un élément de liaison (3a, 3b), en particulier un réseau maillé. A l'état monté, ces dispositifs de fixation enserrent, à la manière d'une pince, des parties de la bande de roulement et des flancs du pneumatique de véhicule. Chaque dispositif de fixation (FV1, FV2) présente des étriers d'accrochage (1) qui reposent, à l'état monté, sur les flancs opposés du pneumatique de véhicule et entre lesquels est disposé au moins un étrier de tension (2) qui est associé à la bande de roulement et sert à l'actionnement des étriers d'accrochage (1). Il est possible, en exerçant une pression en direction de la chaussée, de faire passer le ou les étrier(s) de tension (2) d'une position soulevée (figure 1a) par rapport à la chaussée, dans laquelle le dispositif de fixation (FVO) est ouvert, à une position abaissée (figure 1b), dans laquelle le dispositif de fixation (FVO) est fermé.
