technical field

The utility model relates to a locomotive frame, in particular to a locomotive frame suitable for scooter locomotives.

Background technique

Please refer to Fig. 1 and Fig. 2, which are respectively the top view and the front view of the existing locomotive frame. Box connection pipe 86, two rear shock absorber supports 87, one front connection pipe 88, two front connection pipe reinforcing pieces 881 and one tail section connection pipe 89. Wherein, the upper end of the main pipe 83 is connected to the lower end of the head pipe 82, and the lower end of the main pipe 83 is bent towards the rear end of the vehicle frame 80 and connected to the front connecting pipe 88; both sides of the front connecting pipe 88 are connected to the lower end of the secondary pipe 84; The front ends of the secondary pipes 84 are connected to the left and right sides of the main pipe 83 , and each secondary pipe 84 extends to the rear end of the vehicle frame 80 in an integrated manner.
