Detailed Description

The following is a further detailed description of the embodiments:

reference numerals in the drawings of the specification include: front bracket 1, cross arm frame tube 11, vertical arm frame tube 12, transverse fixing strut 13, steering column fixing sleeve 14, frame plate 2, connecting rod 21, mounting seat 22, and mounting plate 3.

Example 1

Referring to fig. 1, a cross-country motorcycle frame, substantially as shown in fig. 1-2, comprises a front bracket 1 and two sets of frame plates 2, wherein the front bracket 1 comprises a cross arm frame tube 11, a vertical arm frame tube 12, a transverse fixing strut 13 and a steering column fixing sleeve 14. One end of the cross arm frame tube 11 and one end of the vertical arm frame tube 12 are fixedly connected to a steering column fixing sleeve 14, and the other end of the cross arm frame tube 11 is fixedly provided with a transverse fixing strut 13. The two groups of frame plates 2 are symmetrically and fixedly arranged on two sides of the transverse fixing support rod 13, and the same position of the bottoms of the two groups of frame plates 2 is provided with a mounting hole. A connecting rod 21 is fixedly connected with the mounting hole, a mounting seat 22 is fixedly arranged on the connecting rod 21, and the mounting seat 22 is used for mounting an engine and a motorcycle rear suspension assembly. One side of the engine is fixedly mounted to the mounting block 22 and the other side of the engine is mounted to the vertical arm frame tube 12.

The present embodiment adopts the deck 2 to save much space, especially vertical space, compared with the tubular structure. By securing the engine on one side to the upright arm frame tube 12 and on the other side to the mount 22 of the frame plate 2, and simultaneously securing the rear suspension assembly to the mount 22, a stronger overall structure is achieved. When the motor-bicycle is used, the strength is very necessary, so that the stability of the motor-bicycle can be ensured under difficult road conditions, and the driving safety and reliability are improved.
