The invention discloses a steering gear assembly and a vehicle. The steering gear assembly comprises an input shaft and an output shaft, and the input shaft is sleeved with an eccentric shaft; the small-tooth-difference planet wheel mechanism comprises a small-tooth-difference planet wheel, a retainer and a gear ring, the retainer is in power connection with the input shaft, and the small-tooth-difference planet wheel is arranged outside the eccentric shaft in a sleeving mode; the retainer is in power connection with the small-tooth-difference planet wheel to drive the small-tooth-difference planet wheel to eccentrically rotate relative to the input shaft, the small-tooth-difference planet wheel is meshed with the gear ring, and the gear ring is in power connection with the output shaft; the motor assembly is in power connection with the eccentric shaft, and the locking mechanism is used for selectively locking the gear ring or the motor assembly. According to the steering gear assembly, steering modes with three functions can be achieved, the overall structure is small in occupied space, the assembly technology is simple, and cost is low.
