SYSTEM WITH MOTOR-REDUCER FOR TWO-WHEEL OR THREE-WHEELED VEHICLES INSTALLED COAXIALLY WITH VEHICLE CARRIAGE, AND VEHICLE WITH SUCH SYSTEM Russian patent published in 2019 - IPC B62M6/55 

FIELD: machine building.

SUBSTANCE: group of inventions relates to machine building, particularly to systems with gear motor for vehicles. System with geared motor for two-wheel or three-wheeled vehicles with bicycle frame with connecting rods comprises motor with external rotor arranged outside the stator and planetary reduction gear installed in stator cavity. System is installed coaxially with carriage by means of bushing, which shape is adapted for its introduction into carriage cavity so that axes of rotation of electric motor, reduction gear and rod of connecting rod coincide, and electric motor and reduction gear are located outside the frame. Motor-reducer is located inside bell-shaped casing. Proposed system comprises barrel. First side barrel is rigidly connected with bicycle frame by means of connecting rod of connecting rod shaft. From the second side the barrel is opened so that its outer part acts as the stator support. Its inner part forms a gear with internal teeth of the planetary reduction gear. Two-wheel or three-wheeled vehicle comprises system with geared motor.

EFFECT: higher efficiency of the motor.
