That is to say, first crossbeam 1, first longeron 3, second crossbeam 2, second longeron 4 surround into the square frame structure that has "mouth" style of calligraphy structure for sub vehicle frame 10 simple structure, it is compatible better, and "mouth" style of calligraphy closed loop structure has formed complete biography power route, is favorable to improving the collision resistance of sub vehicle frame 10, collision biography power efficiency and sub vehicle frame 10 rigidity, still is favorable to promoting the modal rigidity of sub vehicle frame 10.

The first longitudinal beam 3 and the second longitudinal beam 4 are collision longitudinal force transmission paths, and can transmit the collision force received by the first cross beam 1 to the second cross beam 2 along the longitudinal direction and also can transmit the collision force received by the second cross beam 2 to the first cross beam 1 along the longitudinal direction.

Optionally, at least one of the first cross beam 1, the first longitudinal beam 3, the second longitudinal beam 4, and the second cross beam 2 is a tubular beam. The tubular beam is constructed into a tubular structure with an internal cavity, the forming process is simple, the strength after forming is high, the mold universality of the tubular beam is high, and the mold structure does not need to be changed for tubular beams with different lengths, so that the mold cost is remarkably saved.

Referring to fig. 1-4, the first transverse beam 1 comprises an intermediate pipe section 11 between the first longitudinal beam 3 and the second longitudinal beam 4 and free pipe sections on both sides of the first longitudinal beam 3 and the second longitudinal beam 4, which free pipe sections are connected to the intermediate pipe section 11. In the embodiment shown in fig. 1-4, the free pipe section comprises: the first free pipe section 121 located on the left side of the first longitudinal beam 3 and the second free pipe section 122 located on the right side of the second longitudinal beam 4, both the first free pipe section 121 and the second free pipe section 122 are connected with the middle pipe section 11.

In the embodiment shown in fig. 3-4, a secondary impact beam 5 is arranged on the side of the first beam 1 away from the second beam 2, and the secondary impact beam 5 is connected with the first beam 1 through a secondary energy absorption box 6.

Optionally, the secondary crash boxes 6 are detachably mounted on the free tube sections at both ends of the first beam 1. In other words, the secondary energy absorption boxes 6 are respectively arranged on the first free pipe section 121 and the second free pipe section 122, and the secondary energy absorption boxes 6 are detachably mounted on the corresponding free pipe sections. Like this, to different motorcycle types, can dispose different vice crashproof roof beam 5 and vice energy-absorbing box 6, be favorable to realizing the platform sharing, be convenient for simultaneously change damaged vice crashproof roof beam 5 and vice energy-absorbing box 6, this design of disassembling formula makes sub vehicle frame 10's collision maintainability improve by a wide margin. When the first cross beam 1 is located on the side, facing the front of the vehicle, of the second cross beam 2, namely the first cross beam 1 is a front cross beam, the auxiliary anti-collision beam 5 is a front auxiliary anti-collision beam. When the front of the vehicle is collided, the auxiliary anti-collision beam 5 can transmit collision energy to the first cross beam 1 through the auxiliary energy absorption box 6 and further to the first longitudinal beam 3, the second longitudinal beam 4 and the second cross beam 2.

When the auxiliary frame 10 is installed at the front part of the vehicle 100, the lengths of the auxiliary anti-collision beam 5 and the auxiliary energy absorption box 6 of different vehicle types can be designed, and the first cross beam 1, the first longitudinal beam 3, the second longitudinal beam 4 and the second cross beam 2 are reserved, so that the purpose of platformization compatibility is achieved. That is, different front-mounted configurations can be satisfied by only changing the secondary impact beam 5 and the secondary crash box 6.

In addition, the secondary crash boxes 6 are arranged on the first free pipe section 121 and the second free pipe section 122, and compared with the arrangement on the middle pipe section 11, the transverse span between the two secondary crash boxes 6 is larger, so that when the secondary crash beam 5 is impacted, the impact force can be better transmitted to the first cross beam 1 through the secondary crash boxes 6.

In the embodiment shown in fig. 3-4, a first cross member diagonal brace 7 is respectively arranged between the first longitudinal member 3 and the first free pipe section 121, and between the second longitudinal member 4 and the second free pipe section 122. When the subframe 10 deals with a small offset collision working condition, the first cross beam inclined strut 7 transmits the collision force to the corresponding longitudinal beam, for example, when the left side of the subframe 10 is subjected to offset collision, the first cross beam inclined strut 7 on the left side transmits the collision force to the first longitudinal beam 3; when the right side of the subframe 10 is biased, the first cross member diagonal strut 7 on the right side transmits the impact force to the second longitudinal member 4.

In the event of an offset collision of the vehicle 100, the first cross member diagonal brace 7 can transmit a force in the lateral direction, so that the collision force is transmitted to the lateral direction, and the vehicle body can slide laterally, thereby reducing the intrusion amount. When the vehicle model does not consider the small deflection collision working condition in the development process, the first cross beam inclined support 7 can be cancelled. For example, when the subframe 10 is applied to a rear-drive vehicle 100 without a front power train, the first cross member diagonal support 7 may be eliminated to satisfy the NVH performance of the vehicle 100. That is, the first cross beam diagonal bracing 7 can be selectively added or removed according to different vehicle model development strategies.

And reinforcing beam inclined supports 9 are arranged between the first longitudinal beam 3 and the first cross beam reinforcing beam 8 and between the second longitudinal beam 4 and the first cross beam reinforcing beam 8. When the auxiliary frame 10 deals with a small offset collision working condition, the first cross beam inclined support 7 transmits the collision force to the corresponding longitudinal beam, the longitudinal beam transmits the collision force to the corresponding reinforcing beam inclined support 9, and the reinforcing beam inclined support 9 transmits the collision force to the first cross beam reinforcing beam 8 to form a complete transverse force transmission path. For example, when the left side of the subframe 10 is subjected to offset collision, the first cross member diagonal brace 7 on the left side transmits the collision force to the first longitudinal member 3, the first longitudinal member 3 transmits the collision force to the reinforcing beam diagonal brace 9 on the left side, and the reinforcing beam diagonal brace 9 transmits the collision force to the first cross member reinforcing beam 8; when the right side of the auxiliary frame 10 is subjected to offset collision, the first cross beam inclined support 7 on the right side transmits the collision force to the second longitudinal beam 4, the second longitudinal beam 4 transmits the collision force to the reinforcing beam inclined support 9 on the right side, and the reinforcing beam inclined support 9 transmits the collision force to the first cross beam reinforcing beam 8.

In response to a small deflection condition, the impact force borne by the subframe 10 is high, so that the number of the first cross beam diagonal braces 7, the first cross beam reinforcement beam 8 and the reinforcement beam diagonal braces 9 can be increased at the same time, as shown in fig. 3 to 4. If the vehicle model does not consider the small deflection condition during development, the first cross beam inclined support 7, the first cross beam reinforcing beam 8 and the reinforcing beam inclined support 9 can be simultaneously cancelled, as shown in the figures 1-2.

Alternatively, the first beam reinforcement beam 8 and the reinforcement beam diagonal bracing 9 can be tubular beams, thereby being beneficial to further reducing the cost of the die and improving the sharing performance of the die. The first cross beam reinforcing beam 8 and the reinforcing beam inclined support 9 can also improve the local dynamic rigidity of the auxiliary frame 10.
