Definitions

  • This invention relates to off-the-road tires, more specifically, this invention relates to a pneumatic all-terrain vehicle tire. Background of the Invention
  • All-terrain vehicles are relatively lightweight with a relatively low center of gravity.
  • Early three wheel versions had knobbly tires having small square block elements and a relatively shallow tread depth.
  • the tires are of a slightly larger size than the more lightly loaded front tires.
  • the tires In aggressive off-the-road applications, the tires must have a very open tread pattern that employs elongated lugs which provide effective straightline or drawbar traction to enable the vehicle to climb hilly and rough terrain, as shown in U.S. Design Patent No. 308,038. Additionally, the tread must provide excellent lateral traction for vehicle stability during turning maneuvers as is disclosed in U.S. Patent No. 5,259,429.
  • the tire disclosed in that patent employs a repeating pattern of long, intermediate length and short lugs arranged to provide improved traction. The arrangement of these lugs is such that each lug wraps completely over the tread shoulder portion.
  • the lugs are also circumferentially relatively closely spaced such that numerous lugs are in the footprint of the tire at any one time.
  • the tire made according to this prior art invention is considered one of the best mud tires in its class according to its manufacturer.
  • the circumferential space between the adjacent lugs is commonly referred to as a soil discharge channel.
  • the channels extend generally from the centerplane of the tread axially outwardly over the tread shoulder. Once this area is packed with mud, the tread effectively looses its abihty to provide any traction. This is because the lugs are buried in the packed mud giving the tire the appearance of a slick or racing tread devoid of grooves.
  • An objective of the present invention is to provide a tread pattern which is self -cleaning in wet clay soil conditions. It is a further object that the tread design have good handling and traction performance on firm soils.

  • the channel at the axially inner location (61) and the channel at the axially outer location (62) as illustrated are aligned axially around the circumference of the tread.
  • each channel at each axially inner location (61) and each axially outer location (62) is in the range of 1 cm to 4 cm, preferably about 2 cm.
  • the opening at the axially inner location (61) is between an axially inner end of an elongated shoulder lug (40) and an axially inner end of an elongated lug (42).

  • the channels minimum opening (S) at the axially inner location (61) is intersected by a circumferentially extending and parallel plane (A) between the lugs (40,42) and by a plane (B or C) between the axially outermost point of the axially inner portion (40A,42A) and at the axially innermost point of the axially outer portion (40B,42B) of the lugs (40,42).
  • each lug (40,42) of the first and second row (1,2) has an enlarged circumferentially extending lug head (43) located at an axially outer end (47) of the axially inner portions (40A,42A) lugs (40,42), more preferably the lug heads (43) of the rows (1,2) are respectively axially aligned and spaced from the equatorial plane.
  • the enlarged lug heads (43) of the lugs (40,42) of the first and second rows (1,2) are substantially aligned with the axially inner end (45) of the adjacent axially outer portion (40B,42B) of the lugs (40,42).
  • the enlarged lug head (43) of the lugs (40,42) of the first and second row are axially inward of the axially outer location (62) between the lug end (45) axially outer portion (40B,42B) of the lug (42).
  • the lugs (40,42) extend from the inner tread (13) a radial distance (D) of about 1.9 cm or more, preferably about 2.5 cm. This deep non-skid tread (12) is superior in traction in wet or sloppy soil conditions.
  • the channels (60) are arranged such that as the tire (10) rotates and the lugs (40,42) enter the footprint or ground-contacting portion at least two of lugs (40) and two of lugs (42) or three soil discharge channels (60) are engaging the soil on one or both tread halves.
  • the soil or mud is quickly expelled either axially over the shoulder or circumferentially through the channels locations (61,62).
  • the mud cannot pack around these deep lugs (40, 42) due to the unique lug spacing and the circumferential continuous open channels at locations (61,62,63) between the soil discharge channels (60) which actually prevents mud from packing in the tread pattern as the tire (10) rotates.
  • An important feature of the tread (12) of the current invention of the preferred embodiment tire is the circumferentially extending enlarged lug heads (43). These features enhance the ride of the tire (10) when the ground is firm by insuring that there is a sufficient lug contact with the road to prevent these tall lugs (40,42) from squirming as they enter or leave the tire's footprint or contact patch as the tire rotates. Additionally, as can further be observed from the drawings the lugs (40,42) are arranged such that at least two lugs on the tread are in contact along a one-inch wide axial band at any circumferential location of the tread. That is, if one draws a one inch wide band axially across the tread the band will intersect at least two lugs, preferably the band width is substantially less than one inch.
  • This tread according to the invention has less than 33 % of the tread area contacting a paved surface, preferably as shown about 25 % .
  • Each lug (40,42) has a somewhat inclined axially inner portion (40 A, 42 A) as well as a more lateral inclination of the axially outer portion (40B,42B) which enhances the tire's traction performance. As shown the outer portions (40B,42B) each have a narrow slot or groove (70) to further enhance traction.
  • the inner portions (40A,42B) having a narrow axially inner end, which progressively widens toward the enlarged lug head (43). This narrow end between the leading edges (67) and trailing edges (68) is designed to penetrate the soil due to the reduced axial width. Once the end penetrates the soil the leading edge (67) curves to a more lateral inclination giving an increased biting edge.
  • the inclined axially inner portions (40A,42B) provides a tremendous amount of traction improvement, while the axially outer portions (40B,42B) provide additional increased forward traction due to the lateral inclination. As further illustrated in FIGURE 5, the locations (62) do not have to extend full depth as shown in the preferred embodiment tire of FIGURES. 1, 2, 3, 4 and 6.
  • the space between the axially inner portion (40A,42A) and the axially outer portion can be bridged by a tie bar (53) of a reduced depth. It is believed important that this connection (53), between the lug portions, should leave an opening having a depth of at least 50% of the lug depth (D) for the circumferentially continuous open channel soil flow characteristics to be maintained. Lesser amounts of opening are believed to be too restrictive in terms of flow and therefore less desirable.
  • the circumferentially continuous open channels as shown in the plan view of Fig. 2 has an opening having a minimum axial width of (S).
  • This minimum opening width is preferably at least 1 cm, more preferably at least 2 cm.
  • this minimum opening axial width (S) in each lug (40,42) of the first or second row is axially ahgned around the circumference of the tire. That is the minimum opening width (S) in each channel can be intersected by a parallel plane (A,B, or C) that is parallel to the centerplane of the tread.
  • the three circumferential channels (61,62,63) need not have the minimum openings axially ahgned around the circumference of the tread (12) as shown, but at a minimum these openings should be such that a plane (A,B, or C) would intersect each opening.
  • the contact patch as measured on a hard surface has the outer channels in the interior of the patch so that at least a portion of the axially outer lug portions (40B,42B) are in the contact patch. As shown these axially outer openings are located within the lateral extremes of the contact patch because if they are positioned too close to the shoulder of the tread, they have almost no assistance in tread cleaning through the channels (61 ,62,63).
  • the opening at location (62) can alternatively be almost of a constant width but in that case the opening should have a minimum axial spacing S of about 1-2 cm or greater to insure that soil can rapidly flow through the opening.
  • the opening of the channel between the axially inner portion (40A,42A) and the axially outer portions (40B,42B) between the circumferential location of the minimum opening width (S) and extending toward the trailing edges (68) preferably diverges. This diverging of the channel in this area between lug portions is believed to help the flow of mud as well as provide a mud releasing feature that help the soil to quickly dislodge from the tread as the tire rolls through the mud.
  • the channels provide flow paths that push into the soil discharge channels (60). Because the three circumferentially continuous open channels (61,62,63) provide an unobstructed path in the circumferential direction, the mud is thrown out the back of the tire as the footprint clears the ground thus leaving three open circumferential channels (61,62,63). These channels (61,62,63) actually helps clean the mud between the circumferentially adjacent lugs (40,42) by allowing water/moisture to get under the mud and dissolve it from the bottom up as well as from the top down. In very wet conditions the circumferential channels (61,62,63) tend to pump water into the soil discharge channels (60) actually washing the soil out of the channels.
  • the tread as disclosed frees a portion of lugs biting edges under these worst case conditions enabling the tread to continue to provide traction.
