The utility model relates to a front axle master pin locking structure with double locking pins. The front axle master pin locking structure comprises a front shaft, a master pin hole is arranged on the front shaft, a master pin is installed in the master pin hole, a pin locking hole is respectively arranged at the upper end and the lower end of the master pin hole, the two pin blocking holes are distributed on the left side and the right side of the master pin, two wedge-shaped locking pins are installed in the pin locking holes and locked through locking nuts, and the locking pin on the upper portion of the master pin hole is shorter than the locking pin on the lower portion of the master pin hole. According to the front shaft master pin locking structure with the double locking pins, the two pin locking holes are arranged at the upper end and the lower end of the master pin hole respectively and distributed on the left side and the right side of the front shaft, by means of the double pin locking structure, stressing points of the master pin are increased, and the stressing states of the master pin are improved, so that the relative position of the master pin can be fixed, four-wheel positioning parameters of the front shaft can be guaranteed, phenomena of braking shaking and braking deviation are reduced, and the front axle master pin locking structure is convenient to assemble and disassemble.
