The invention relates to the technical filed of vehicle steering racks and in particularly relates to a gear hollow shaft steering rack, which comprises a steering rack, wherein a traction device and a wheel pair are arranged on the steering rack, a traction motor is arranged on the pair wheel and is connected with a gear box through a hollow shaft; the traction motor is also connected with the hollow shaft through a diaphragm coupling joint I; a driving gear is arranged on the hollow shaft; the hollow shaft is connected with the driving gear through a diaphragm coupling joint II; and a driven gear is arranged on the wheel pair; the driving gear and the driven gear are engaged. According to the gear hollow shaft steering rack, the application requirements of electric and internal combustion locomotives and heavy road maintaining engineering vehicles that the light weight and speed level standard are high can be met; by virtue of the driving gear hollow shaft structure of the steering rack, the gear application condition can be greatly improved, the service life of a gear pair is prolonged, the failure rate of the gear is reduced and the application and maintenance cost of a user is lowered.
