The invention provides an electrohydraulic steering mechanism of a steering wheel type tracked car. The electrohydraulic steering mechanism of the steering wheel type tracked car consists of a track walking device, a steering wheel, a steering shaft, a coupling, an encoder, a programmable controller, an EP variable hydraulic pump, a speed reducer, a quantitative motor and a pump flow pedal, wherein the steering wheel, the EP pump, the programmable controller and the speed reducer are all arranged on the track walking device; the steering shaft is connected with the steering wheel; the encoder is arranged on the steering shaft; the quantitative motor is arranged on the speed reducer; and the programmable controller is electrically connected with the encoder and the EP pump. The electrohydraulic steering mechanism of the steering wheel type tracked car has no such traditional parts as a clutch, a brake, a friction plate and a transmission, so that the structure is simple; a controller changes the displacement of the pump to realize the speed difference of a driving motor so as to realize the steering, so that the power is used more fully, a lot of energies are saved, and meanwhile, the steering is more precise, the operation is simpler, the demand on the technical merit of drivers is lower, and the working efficiency and the fault tolerance and safety of a system are improved.
