MOTORISED UNIT AND GROUPING MODULE Russian patent published in 2001 - IPC

FIELD: agricultural engineering. SUBSTANCE: motorised unit has frame, engine, reducer, wheels, seat, control mechanism with steering wheel, brake, front and rear members of working tool hitching members. Frame part connecting member is formed as longitudinally extending sleeve within which shaft is fixed by bearings. Flange is fixed in rear end part of sleeve on shaft, and thrust washer is located in front part of sleeve and fixed by pin. Restrictor is attached to sleeve rear part in horizontal plane for restricting rotation of sleeve when one of wheels is lifted. Length of shaft is greater than length of sleeve, and shaft free end with butt joining openings is secured in frame rear part through detached connection. Frame front part formed as horizontal beam with end bent upward is attached to sleeve by welded-on brackets. Seat, luggage carrier, front shield, control mechanism, brake control pedal and accelerator control pedal are mounted on frame front part. Brake and accelerator are connected through cables to control lever which is pivotally fixed to frame rear part. Control lever is connected through cables to accelerator and brake. Brake control pedal is connected to brake by cable. Control mechanism with steering wheel is equipped with shaft arranged in column and having gear positioned at its lower end and engageable with toothed sector pivotally secured to frame and to transverse steering tie-rod of front driven wheels. Engine is mounted on frame rear part. Damper is equipped with additional chamber. Grouping module has frame, sleeve and steering control mechanism, with all mentioned parts of grouping module being made similar to these parts of motorised unit. EFFECT: increased efficiency, improved ecology control and increased versatility. 11 cl, 9 dwg
