SELF-PROPELLED MINE MACHINE Russian patent published in 2024 - IPC E21F13/02 B62D5/06 B60K7/00 B62D7/16 B62D7/20 

FIELD: mining equipment.

SUBSTANCE: self-propelled mine machine comprises a chassis with a frame, a first pair of propulsors, a second pair of propulsors, mechanisms for controlling rotation of the first and second pairs of propulsors. Each of the propulsors is made in the form of a motor-wheel. First pair of motor wheels is installed in fixed supports with possibility of rotation around vertical axis on beam, which is connected to the frame with possibility of swinging around the horizontal axis of symmetry of the machine. Second pair of motor wheels is installed in fixed supports with possibility of rotation around vertical axis on the frame. Each control mechanism includes a three-arm lever, a hydraulic cylinder connecting the frame with the first arm of the three-arm lever, crosswise control rods connecting each propulsor with the second arm of three-arm lever. Third arms of the three-arm levers are mechanically connected to each other. Each propulsor comprises a steering knuckle with an engine fixed in it and installed in fixed supports on rotary axes.

EFFECT: higher accuracy of maneuvering when moving a self-propelled mine machine.
