HYDRAULIC MOTOR-WHEEL Russian patent published in 2024 - IPC F01C1/10 F03C2/08 

FIELD: transport machine building.

SUBSTANCE: invention relates to transport machine building, particularly, to transport, road construction and other mobile machines with drive wheels, as well as vibratory rollers. Hydraulic motor-wheel comprises a housing with internal teeth, a rotor with two toothed rims eccentrically installed in the housing, outer one of rims is engaged with the inner teeth of the housing, and the inner one is engaged by means of rollers with gear shaft teeth, which form variable-volume working chambers in the engagement zone with the inner teeth of the rotor, distributors rigidly connected with shaft-pinion, in which there are cavities for supply and discharge of working fluid, which are interconnected by main lines with reversible distribution unit. Hydraulic motor-wheel also contains a speed sensor connected to a speed sensor disk installed on one of the distributors, and a parking brake equipped with a mechanical release mechanism. Parking brake comprises a brake housing with internal teeth engaged with friction discs, which are engaged with an adapter, which has external and internal teeth engaged with a gear shaft, it contains piston, which together with brake housing forms working cavity of brake for brake release, and is connected with pressure plate, which is actuated by springs located in housing of bearings. Mechanical release mechanism consists of a bolt, which is located in a bushing connected to a guide, and which is engaged with a rod connected to a pin, which is located in a bushing with external teeth, which is engaged with an adapter with internal teeth and a hub with internal teeth and is connected to a spring.

EFFECT: invention is aimed at creation of a hydraulic motor-wheel with a speed sensor and a parking brake with a mechanical release mechanism.
