Theory of turn bodies of mountain tandem wheeled self-propelled chassis

The theory of turning of the adaptive bodies of mountain tandem-wheeled motor vehicle chassis intended as power units in small farms, is offered. A calculating formula for radius of turning is deduced for two variants: drive of all the six driving and steered wheels and without drive of front steered wheels. By the calculating formula are considered: lateral leading away of front steered wheels; re-distribution of the load on the wheels; hook resistance; coefficient of the differential gear black system; distance between centers of jointed in pairs tandem wheels constituting a counter-balanced suspension and other geometric, kinematic and dynamic parameters. The research results can be used in determining of exploitation indices of perspective mobile power units in the stage of their design.
