Speeds of agricultural tractors

Gorodetskiy K.I., Sharipov V.M., Alendeyev Y.M., Shevelev A.S., Muratova S.K.


Presentation method for speed series of agricultural tractors in the matrix form was proposed and described. That to a certain extent reveals the kinematic scheme of gear boxes and ways of creation and modification of their constructions depending on specified requirements. The matrix form of speed series presentation helps to develop new, more effective kinematic schemes for compound gear boxes of agricultural tractors.

Theoretical investigations of wheeled tractor frame oscillations during the operation in tractive mode

Schetinin Y.S., Yesenovskiy-Lashkov M.Y., Sergeyev A.I.


Possibility of self-excitation of wheeled tractor frame oscillations in longitudinal plane during the operation in tractive mode is theoretically substantiated. Dependence of rolling radius of a pneumatic wheel on vertical load and on driving moment level, mathematical model describing pneumatic wheel rolling under variable vertical load and two-mass lineal model describing tractor frame oscillations in longitudinal plane are used.
