The invention discloses a multi-gear large-range speed-adjustable heavy-load rack rail vehicle and a speed adjusting method. The rack rail vehicle comprises a cockpit, a driving unit, a power unit, an auxiliary cockpit, an energy storage compartment and a transfer flat car. The power unit comprises a three-phase motor, a torque sensor, a first linear motor, a second linear motor, a synchronizer, a multi-stage gear, a shell and a load-sensitive pump; an output shaft of the three-phase motor is connected with an input shaft of the multi-stage gear, and an output shaft of the multi-stage gear is connected with an input shaft of the load-sensitive pump; the torque sensor is installed between the three-phase motor and the multi-stage gear, the position of the linear motor is adjusted according to the torque change of the output shaft of the three-phase motor, and the gear of the rack rail vehicle is changed. Through the mode of combining the motor, the multi-stage gear and the load-sensitive pump, the rack rail vehicle hydraulic system keeps proper flow under different loads, the working efficiency of the system is improved, the self-adaptive capacity of the rack rail vehicle is improved, the bearing capacity of the rack rail vehicle is improved, the speed adjustable range of the rack rail vehicle is widened, and the vehicle speed change is more stable.
