HYDRAULIC PUMP ASSEMBLY Russian patent published in 2018 - IPC G05D7/01 B60W10/119 F04B1/20 F04B1/30 

FIELD: control; regulation.

SUBSTANCE: invention relates to the hydraulic pump assembly and can be used in including the wet type disc brakes system for the torque distribution between the road vehicle all-wheel drive front and rear axles and / or between the left and right wheels of vehicle with two- or four-wheeled gearing. Assembly includes configured to rotate piston drum (20) with at least one centrifugal arm (23), which is pivotally attached to the drum (20) with possibility of the radial movements provision between the radial projections (20') under the centrifugal force effect during the drum (20) rotation and arranged to control the valve member position, the ball (22) located at the formed in the drum (20) hole open end. Assembly comprises the predetermined friction surface (28) arranged between the lever (23) and the protrusion (20'), and elastic means for the resilient axial force application displacing the lever (23) to the protrusion (20').

EFFECT: invention is aimed at improvement of the centrifugal regulator dynamics control.
