Assembly comprising a chassis for a variable-track machinery equipment such as a sprayer-type agricultural machinery equipment or a straddle machinery equipment
The present invention relates to an assembly which includes: a chassis for a mobile land vehicle, in particular an agricultural or public works vehicle; at least two half-crossmembers (21) mounted telescopically on the chassis; wheel mountings (27) pivotably mounted on each one of said half-crossmembers; steered wheels rotatably mounted on said mountings; and a device for controlling the direction of the wheels. The assembly is characterized in that it includes means (39, 41, 47) designed, for a certain position of two half-crossmembers, to increase, upon the pivoting of the wheels, the opening of the said wheels relative to the opening of the wheels resulting from the same pivoting and another position of the two half-crossmembers.
