    FIELD OF THE INVENTION
    [0001] The present invention is in the field of suspensions for vehicles. More specifically, the present invention relates to suspensions for vehicles using a track drive system. Background of the invention
    [0002] Track driven vehicles are commonly used in the construction and agricultural industries. Track driven vehicles are commonly very heavy vehicles that require a substantial load to be carried by each track and track suspension on the vehicle. For this reason, prior art suspensions have minimal displacement and articulation with the roller and idler wheels in contact with the track. Lack of articulation of the idler and roller wheels limits the tractive force of the track and also causes forces to be transmitted to the vehicle from the idler and roller wheels. This lack of articulation can make travel less comfortable for the driver of the track-driven vehicle and in some cases can lead to excessive wear of the vehicle part.

Aligning these geometry axes 9, 17, 22 reduces the tendency of the tension of the rubber mat 3 or force transmitted through the rubber mat 3 to cause movement of the front rocker assembly 16 or front yoke member 10. To have minimal impact about the position of the components of the track suspension 2, the front axis line 28 formed approximately through the axis of the front yoke joint 9, the axis of the front rocker joint 17, and the front idler axis 22 should substantially divide angle α between the leading edge of the rubber mat 29 and the leading lower edge of the rubber mat 30.

Angle w will normally be in the range between 165° and 195°. Angle w will preferably be in the range between 168° and 192°. The angle w will most preferably be in the range between 171° and 189°. Angle w will even more preferably be in the range between 174° and 186°. Angle w will most preferably be in the range between 177° and 183°.
    [00061] The rear yoke joint shaft 8, the rear rocker joint shaft 18, and the rear idler shaft shaft 21 must be substantially aligned. Aligning these geometry axes 8, 18, 21 reduces the tendency of the tension of the rubber mat 3 or force transmitted through the rubber mat 3 to cause movement of the rear rocker assembly 15 or rear yoke member 7. To have minimal impact about the position of the components of the track suspension 2, the rear axis line 31 formed approximately through the rear yoke joint axis 8, the rear rocker joint axis 18, and the rear idler wheel axis 21 should substantially divide the angle δ between the trailing edge of the rubber mat 32 and the trailing lower edge of the rubber mat 33. An angle ε is formed between the trailing axis line 30 and the trailing edge of the rubber mat 32. A angle T is formed between the rear axis line 30 and the lower rear edge of the rubber mat 33. The difference between angle ε and angle t must be smaller than 14th. The difference between angle ε and angle t will preferably be less than 11°. The difference between angle ε and angle t will even more preferably be less than 8°. The difference between angle ε and angle t will most preferably be less than 5°.
    [00062] An angle α is formed between the rear yoke joint 8, the rear rocker joint shaft 18, and the rear idler shaft shaft 21. The angle α must be substantially linear. The angle δ will normally be in the range between 165° and 195°. Angle α will preferably be in the range between 168° and 192°. The angle α will most preferably be in the range between 171° and 189°. Angle α is even more preferably in the range between 174° and 186°. Angle α will most preferably be in the range between 177° and 183°.
