Definitions

  • This invention relates generally to vehicle traction devices and, more particularly, to a traction enhancement device for use with a vehicle having dual tandem wheels. More particularly, the present invention provides enhanced traction for construction trucks having dual wheels that may otherwise become stuck when operating in muddy conditions.
  • interlinked track pads have been proposed that surround the tires and wheels which turn along with the wheels and which spread the weight of the vehicle over a wider surface area to prevent the vehicle from getting stuck.
  • the existing or previously proposed devices have required structures that either surround the outer edges of the tires or included other means for maintaining the track assembly in proper alignment upon the wheels.
  • an enhanced traction device for use on vehicles that have dual tandem wheels for reducing the chances that the vehicle will get stuck in the muddiest of weather conditions. Further, it would be desirable to have an enhanced traction device that maintains its plurality of track pads upon the tandem wheels using a plurality of alignment portions or a spacer positioned to extend between the tandem wheels of the vehicle.
  • An enhanced traction device for use with a vehicle having dual tandem wheels includes a series of generally parallel track pads, each track pad having an alignment portion and a traction portion defining first and second ends.
  • Each traction portion includes an inner surface for contacting the vehicle wheels and an outer surface for contacting ground.

  • a traction enhancement device 100 for use with a vehicle 10 having dual tandem wheels 12 according to the present invention will now be described in detail with reference to Figs. 1 through 8b of the accompanying drawings. More particularly, a traction enhancement device 100 according to the current invention includes a plurality of track pads 110, a first chain 120, and a second chain 125.
  • Each track pad 110 has a traction portion 112 and an alignment portion 116, as shown in Fig. 3b.
  • the traction portion 112 defines first and second ends 112a, 112b, has an inner surface 113a for contacting the wheels 12, and an outer surface 113b for contacting ground.
  • the traction portion 112 may have a generally triangular cross section (as shown in Fig. 4b) or any other appropriate configuration.
  • the track pad 110 may have a width that is sufficient to extend across each set of the dual wheels 12.
  • the first chain 120 may be coupled to the first end 112a of each track pad 110 to maintain a predetermined spacing between the track pad first ends 112a; the second chain 125 may be coupled to the second end 112b of each track pad 110 to maintain a predetermined spacing between the track pad second ends 112b.
  • the chains 120, 125 may be welded to the track pads 110 or coupled thereto in another appropriate manner, and it should be appreciated that the chains need not be coupled at the edges of the first and second ends 112a, 112b as shown in Fig. 3b.
  • predetermined spacing between the track pad first ends 112a may be generally equal to the predetermined spacing between the track pad second ends 112b, or the track pads 110 may otherwise be coupled together to form a series of generally parallel track pads 110 (Figs. 3a and 3b). It should be apparent to one of ordinary skill in the art that "predetermined spacing” as used herein simply means a selected spacing, and that the selected spacing may vary based on factors such as size and spacing of the wheels 12.
  • the first chain 120 may have first and second ends 120a, 120b, and a midlink 124 may selectively couple the first and second ends 120a, 120b of the first chain 120 together to form a loop.
  • the second chain 125 may have first and second ends 125a, 125b, and a midlink 128 may selectively couple the first and second ends 125a, 125b of the second chain
  • each track pad alignment portion 116 may extend generally perpendicularly from a respective traction portion 112 away from a respective traction portion outer surface 113b. As shown in Figs. 6a and 6b, the alignment portion 116 may be configured to pass between the dual wheels 12. In one embodiment, the location of the alignment portions 116 between the dual wheels 12 may keep the traction portions 112 in place on the wheels 12. To minimize damage to the wheels 12 by the alignment portions 116, the alignment portions 116 may contact a spacer instead of the actual wheels 12.
  • a spacer 130 may be configured for fixed attachment to an axle or a wheel 12 so as to be positioned between respective dual wheels 12. In other words, the spacer 130 may be locked together with the axle or wheel 12 in a permanent or non-permanent manner.
  • the spacer 130 shown in Figs. 7a through 7c has first and second faces 132a, 132b and a plurality of load bearing members 134 therebetween.
  • the load bearing members 134 shown in Figs. 7a through 7c are spokes separating the faces 132a, 132b, though other load bearing members (e.g., gear teeth, etc.) may be used.
  • a force transfer member (e.g., alignment portion 116) may be at least temporarily in communication with the spacer (i.e., a load bearing member 134) and a respective track pad traction portion 112 for transferring force from the spacer 130 to the track pad traction portion 112 (Fig. 8b).
  • the load bearing members 134 may have a configuration complementary to a configuration of the force transfer members (e.g., alignment portions 116) so that rotation of the spacer causes the force transfer members to move.
  • a vehicle 10 having dual tandem wheels 12 is provided (Fig. 1).
  • a respective series of generally parallel track pads 110 (Figs. 3a and 3b) may by positioned about a respective set of dual tandem wheels 12 so that the alignment portions 116 are positioned between the dual tires 12, and the midlinks 124, 128 may be used to maintain the track pads 110 in a loop as discussed above and shown in Figs. 4a and 4b.
  • Interaction between a traction portion inner surface 113a and a rotating wheel 12 may cause the traction portions 12 to move and the traction portion outer surfaces 113b to contact a ground surface, thus increasing traction for the vehicle 10.
  • the positioning of the alignment portions 116 between the wheels 12 may maintain the traction portions 112 in line with the wheels 12, and if the spacer 130 shown in Figs. 7a through 7c is fixed to an axle or wheel 12, rotation of the axle and wheels 12 may cause the load bearing members 134 of the spacer 130 to move the force transfer members (e.g., alignment portions 116) as set forth above.
