Tracks used on ATVs TTM-3, 3902, 4902


The manufacturer of tracked terrain vehicle TTM (CJSC «Transport») provides all-terrain vehicle lineups TTM-3, TTM-3902 and TTM-4902 with two different types of tracks (with elastic wideners). These types differ from each other by the design of metal compounds and the type of treadmill.
About  elastic wideners:
In order to reduce the mean soil pressure there is an elastic widener(#1) on the wing of the metal truck (# 3). It has a  screw connection. The elastik widener is a rubber molded piece with several layers of armoured parts inside (# 2):

When you are driving on snow or swamp, elastic wideners are folded according to the reaction of support surface. The folding angle is about 12º -15º. When you are driving over a hard surface (ledge, tree stump, rock, etc.), they are fold at an angle of 90º, restoring its position after obstacle.

The design is patented (patent number 46729)

Types of tracks:

1. With open joint.(OJ)

Connection of metal truck (# 1) is made with metal pegs (#2). These metal pegs are made with a special unique treatment. Circlips (# 3) hold the pegs from falling out of the truck. 



  • easy construction.

It helps to reduce time for assembling and disassembling trucks, removing tracks from the machine.

Disadvantages(compared with RMJ):

  • higher rates of peg’s deterioration (# 2)
  • regular monitoring of belt tension;
  • treadmill does not have a rubber layer(increasing the tendency of forming ice between the treadmill and the tire track roller)

The maximum capacity of tracks with OJ up to 8 000 km.

Average capacity 5 000-7 000 km.

2. With rubber-metal joint  and rubberized running track.(RMJ)

Connection of metal truck is made with rubberized metal peg (# 2). The pegs are pressed into track by special tools. Treadmill on the track is rubberized.


  • Rubber layer bertween pegs and tracks(the resource of track is increased);
  • Rubber layer on a track treadmill (the resource of track is increased)

 Disadvantages(compared with OJ):

  • complicated construction

It requires more time for assembling and disassembling trucks, removing tracks from the machine.

  • higher price(due to complicated production)

 The maximum capacity of tracks with RMJ up to 18 000 km.

Average capacity 11 000-13 000 km.
