Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Furthermore, the auxiliary bracket assembly includes a "human" shaped auxiliary bracket I 21 and two auxiliary brackets II 22. The middle part of the auxiliary bracket I is connected to the middle part of the reinforcing beam 1 by bolts; the two ends of the auxiliary bracket I are respectively connected to the auxiliary bracket II 22 by screws, and the transmission is installed through the two auxiliary brackets II. Preferably, the end of the auxiliary bracket I is set through the auxiliary bracket II, and a shock-absorbing rubber pad 23 is set between the inside of the auxiliary bracket I and the upper part of the auxiliary bracket II to reduce the vibration of the transmission through the shock-absorbing rubber pad; the shock-absorbing rubber pad is also fixed through the screws connecting the auxiliary bracket I and the auxiliary bracket II.

[0030] Two shock-absorbing rubber pads are arranged at both ends of the "human" shaped auxiliary bracket I, so that the force points of the two shock-absorbing rubber pads form a certain angle, and the two auxiliary brackets II form a certain angle, which has an automatic centering effect on the transmission below, and prevents the transmission from twisting during vibration, so that it can be dynamically automatically centered to reduce the impact on the frame. Preferably, the angle between the force directions of the two shock-absorbing rubber pads is set to be less than 45° to enhance the connection strength between the transmission and the frame assembly, and at the same time, the impact from the transmission on the frame assembly is also alleviated. For driving on poor working conditions, it can effectively prevent the impact of the transmission twisting on the frame, thereby improving safety and durability.

[0031] Specifically, the middle part of the reinforcing beam 1 is upwardly protruded along the length direction to form a reinforcing portion 11, so as to increase the bearing weight of the reinforcing beam through the reinforcing portion; and the front and rear sides of the reinforcing portion located in the middle part of the reinforcing beam 1 are formed with mounting holes 12 connected to the "human" shaped auxiliary bracket I; both ends of the reinforcing beam 1 are extended to form mounting portions I 13 and II 14, wherein the mounting portion I 13 is located above the mounting portion II 14, and the mounting portion I 13 and the mounting portion II 14 are matched with the frame assembly to fix the reinforcing beam 1 between the left frame and the right frame. In this embodiment, the mounting portion I is fixed to the middle part of the left frame and the right frame by screws, the mounting portion II is fixed to the bottom of the left frame and the right frame by screws, and the mounting portion I is fitted with the middle and upper parts of the left frame and the right frame, and the mounting portion II is fitted with the bottom of the left frame and the right frame, so as to ensure the support strength of the frame assembly to the reinforcing beam.

[0032] Grooves are formed above the two ends of the "human" shaped auxiliary bracket I, so that the shock-absorbing rubber pad can be installed through the grooves. The auxiliary bracket II is welded by two U-shaped opening brackets, namely the first opening bracket 221 and the second opening bracket 222. The opening directions of the first opening bracket 221 and the second opening bracket 222 are arranged opposite to each other and welded to each other; a screw mounting hole is formed in the middle of the first opening bracket 221 for mounting with the auxiliary bracket I through screws; a transmission mounting hole is formed in the middle of the second opening bracket 222 for mounting with the transmission, and after installation, the opening of the first opening bracket 221 is perpendicular to the end of the "human" shaped auxiliary bracket I, and the opening of the second opening bracket 222 is arranged opposite to the transmission.

[0033] The utility model installs the transmission through the reinforcing beam and the auxiliary bracket assembly, and the shock-absorbing rubber pad is set to reduce the vibration of the transmission. By setting the force points of the two shock-absorbing rubber pads at a certain angle, the transmission below has an automatic centering effect, which prevents the transmission from twisting during vibration, and makes it dynamically automatically centered, reducing the impact on the frame. The added reinforcing beam can increase the connection strength of the frame assembly, and the impact from the transmission on the frame assembly is also alleviated. When driving on a road with poor working conditions, it can effectively prevent the impact of the transmission twisting on the frame, thereby improving safety and durability.
