3. A powered bogie based on a box beam type foundation as claimed in claim 2, characterized in that: The gap adjustment device also includes a limiting wheel (51) arranged on the top of the motor bracket (5) and used for rolling against the inner top wall of the box beam type base to limit the minimum value of the induction gap.

4. A powered bogie based on a box beam type foundation as claimed in claim 2, characterized in that: The buffer support (7) comprises a buffer spring and / or a telescopic vertical shock absorber.

5. A powered bogie based on a box beam type foundation as claimed in claim 2, characterized in that: The motor bracket (5) is provided with a distance sensor (53) for detecting the spacing size of the induction gap.

6. A powered bogie based on a box beam type foundation as claimed in any one of claims 3 to 5, characterized in that: A second track (12) is fixedly arranged on the top of the box beam type base for rolling contact with a limiting wheel (51); the limiting wheel (51) comprises a rotating shaft (511) and rubber wheels rotatably arranged at both ends of the rotating shaft (511) via bearings.

7. A powered bogie based on a box beam type foundation as claimed in claim 1, characterized in that: The bogie assembly is provided with an anti-derailment mechanism (6); the anti-derailment mechanism (6) comprises guide wheels fixedly arranged on both lateral sides of the bogie assembly and rollingly abutting against the side walls of the box beam type base.

8. A powered bogie based on a box beam type foundation as claimed in claim 1, characterized in that: The chassis (4) is provided with a tread brake (8) for braking the running wheel (41); the tread brake (8) comprises a telescopic cylinder (81), a brake shoe support (82) drivingly connected to the telescopic cylinder (81), and a brake shoe (83) provided on the brake shoe support (82) for frictionally contacting the tread of the running wheel (41).

9. A powered bogie based on a box beam type foundation as claimed in claim 1, characterized in that: The box beam type base comprises a top plate (1), web plates (2) fixedly arranged on both sides of the top plate (1), and a bottom plate (3) fixedly arranged at the bottom end of the web plates (2); a suspension gap (31) is arranged between the two bottom plates (3), and a first track (31) is arranged on the bottom plate (3); and the induction magnetic stator (11) is fixedly arranged on the top plate (1).

10. A method for adjusting the induction gap of a power bogie, characterized in that: Using a powered bogie based on a box beam type base as described in any one of claims 2 to 9, the adjustment method comprises: Collecting the induction gap distance between the motor mover (54) and the induction magnetic stator (11); When the sensing gap distance is greater than the set distance range, the buffer support (7) is controlled to extend the lifting motor bracket (5) until the sensing gap distance is within the set distance range; When the sensing gap spacing is smaller than a set spacing range, the buffer support (7) is controlled to retract and move the motor bracket (5) downward until the sensing gap spacing is within the set spacing range.
