CHASSIS OF SELF-PROPELLED AGRICULTURAL MACHINE Russian patent published in 2023 - IPC A01D67/00 B60K7/00 

FIELD: agriculture.

SUBSTANCE: chassis of a self-propelled agricultural machine contains a frame (7), a bridge of steered and driven wheels (5 and 11), an engine (6), hoods (1), an entrance platform (10), a cabin (14), a front linkage (12), a towing coupler (4), a hydraulic system (8), fuel equipment system (9), control mechanism (13), battery pack (2) and electrical equipment (3). The driving wheel axle beam (11) is built into the frame (7), on which two final drives are coaxially mounted. The drive wheels (11) are installed on the hub of the output shaft of the final drives. The output shaft of the final drive is connected through a planetary mechanism and a spur gear to the input pinion shaft of the final drive. At the splined end of the input gear shaft, actuators of the brake device are installed, placed in an intermediate cup mounted on the final drive housing with a fixed hydraulic motor for driving the drive wheels (11). The hydraulic motor shaft is connected by a splined coupling to the input gear shaft.

EFFECT: design is simplified, the cost of the components used and the reliable operation of the self-propelled agricultural machine when performing the production process are ensured.
