Definitions

• This invention relates to an anti-skid device for vehicles and in particular one suited for car ' s.
• anti-skid devices for cars it has long been known to use snow-chains.
• the chains " increase the grip considerably, but their mounting is time-consuming” and demands in general a certain practice, even if attempts have been made with quick-m ' ountable snow- chains, as well as simpler swift mounted links.
• Snow-chains furthermore have the draw-back that they do not permit any higher speed, which with a great probability result in that most car-drivers or owners are uninterested in snow-chains but for rather extreme cases.
• anti ⁇ skid devices constituted by a number of U-shaped members gripping over the tyre and held in place by a tensioning device.
• the object of the invention is to provide an anti-skid device for motor vehicles and in par ⁇ ticular cars, that is simple to use, that requires a minimum of installation measures, that are cheap to manufacture, that can be used instead of studded winter wheels, i.e. that can
• the friction increasing part of the anti-skid device is in the shape of a belt it can resist the centrifugal forces even at high speed.
• the friction in- creasing belt does not extend over the entire traction of the wheel, but instead only extend over half or a part of the traction of the tyre. In this way the risk of water planing is diminished and the contact pressure against ice and snow is increased.
• the belt can be of rubber o plastic and provi- ded with metal studs or other gripping means.
• the rotatable journaling and mounting of the device can either take place at the. centre of the wheel by means of special devices mounted together with the wheel, but it is of course also possible to mount these devices on the axial shaft or that the hub cap is provided with means capable of cooperating with the anti-skid device.
• Fig 1 shows an anti-skid device in accordance with the invention in a radial section
• fig 2 an alternative central journaling of the anti-skid device.
• the belt 1 is shown in a section and includes two cord layers 3, 4.
• the inner 3 of these extend laterally out into spoke-like elongations of the belt 1.
• These spoke-like elongations 5 extend round the shoulder of a tyre 2 in towards the centre of the wheel.
• the wheeldisk is mounted by means of wheel nuts 7, these are somewhat longer than ordinary type and in their outer ends bolts 8 are used to mount a disk 9,provided with axle shaft 10.On this shaft a bearing 11 is held by a nut 12.
• the bearing, that with its inner race is fixed on the shaft has its outer race fixed in a hub disk 13 provided with spoke-like elonga ⁇ tions 14 jointed to the elongations 5 of the belt 1 by bolt and nut means 15.
• FIG. 2 an alternative embodiment of the central journaling of the anti-skid device is shown.
• the hub disk 17. ith a radial play is journaled between two disks 18 and 18' arranged on a common casing that when the anti-skid device is mounted is pushed over the extra shaft 19 mounted on the wheel disk. Thereafter the common casing is locked on the shaft 19 by aid of a snap-lock or the like.
• the anti-skid device can rotate excentrically relative the wheel without spring action from the spokes.
• the anti-skid device can be fabricated in a number of dimensions that is less than the number of different tyre dimensions, as long as the excentri- city between wheel and anti-skid device can be taken care of by bearing, spokes or the like.
• excentrical rotation permitting means might be included in the joints or in the spokes in some other not described way, without departure from the scope of the invention.
• T e belt shape, of the anti-skid device means that it well re ⁇ sists centrifugal forces without powerful and heavy mounting means. Due to the rotatability the anti-skid device can be made lighter than what is the case with the known devices, this since no driving forces need to be transferred by the positioning means. .
