AUTOMATIC ENLARGER OF ADHESION WEIGHT OF AIRCRAFT TOWING VEHICLE Russian patent published in 2006 - IPC B64F1/22 B60D1/155 

FIELD: ground servicing of aircraft; aircraft transportation facilities.

SUBSTANCE: proposed device has frame-carrier connected with raising hydraulic cylinders by means of vertical guide and spherical support with truck tractor frame. Spherical support is mounted on truck tractor frame for longitudinal motion. Connected with frame-carrier by means of rod is control hydraulic cylinder whose body is rigidly connected with frame of truck tractor in longitudinal vertical plane. Raising and control hydraulic cylinders are interconnected by means of oil line. Rod chamber of control hydraulic cylinder is connected with return line through hole shut-off by piston and with rodless chamber of raising hydraulic cylinder by means of check valve controlled by it. Proposed device smoothly increases adhesion weight of truck tractor at acceleration using aircraft braking energy for recharging the hydraulic accumulator of replenishing unit.

EFFECT: enhanced efficiency; reduced dynamics and improved power parameters.
