FIELD: transport.
SUBSTANCE: propulsion unit includes a platform with a frame mounted on it and a crank-type pendulum oscillation axis fixed to the frame. The pendulum oscillation sector is in the motion plane. The pendulum oscillation axis is between the platform and crank. The pendulum oscillation drive is made in the form of crank gear. The rotary drives of the crank installed on the pendulum and the crank gear are made in the form of chain drive and linked to the rotary drive located on the pendulum oscillation axis. In an other propulsion unit version, on the pendulum oscillation axis there is a crank linked to the crank installed on the pendulum by a gear drive and linked to the rotary drive. The rotary drive is linked by a chain drive to the pendulum oscillation drive made in the form of deadweight crank gear. In both propulsion unit versions the crank arm can be linked to the pendulum by a movable hinge.
EFFECT: reduced energy consumption for propulsion, increased speed and traction effort.
