  • Patent number: 11608129
    Abstract: A track assembly includes an elongated main frame supported for pivotal movement on a transverse axis and having opposite end portions supporting a set of end wheels. An endless flexible belt extends around the end wheels and has an upper run and a lower run for engaging the ground. A plurality of longitudinally spaced bogie wheels are positioned below the main frame and engage the lower run of the belt. The bogie wheels are carried by bogie frames supported for vertical movement and also for tilting movement relative to a plane defined by the axes of the end wheels. The bogie frames are urged or biased downwardly against the lower run of the belt by compression members extending from the main frame and preferably in the form of annular rubber spring members.
