[0042] Embodiment 1

[0043] In a typical embodiment of the present application, a drive component mounting bracket for a hybrid loader is provided, which is used to mount an engine, a generator and a transfer case on a vehicle frame, such as Figure 1-7 As shown, it includes a left front bracket 1, a right front bracket 2 and two rear brackets 3, wherein the left front bracket 1 and the right front bracket 2 are respectively arranged on both sides of the front end of the vehicle frame for installing the engine 5; the two rear brackets 3 are respectively arranged on the left and right sides of the rear end of the vehicle frame 4;

[0044] The rear bracket 3 includes a first mounting module 31, a second mounting module 32 and a third mounting module 33 which are fixedly connected. The first mounting module 31, the second mounting module 32 and the third mounting module 33 are respectively fixedly connected to the engine 5, the generator 6 and the transfer case 7; the rear bracket 3 also includes a mounting plate 34 connected to the vehicle frame, and the mounting plate 34 is fixedly connected to at least one mounting module.

[0045] Specifically, Figure 1 , 2 As shown, the engine 5, two generators 6 and the transfer case 7 are coaxially connected in sequence from front to rear, and are fixedly installed in the vehicle frame through the bracket structure of this embodiment. In order to reduce the cumulative assembly error of the three during installation, two rear brackets with the same structure and symmetrically installed on the left and right sides are designed in this embodiment. The rear bracket adopts an integrated structure to fix the engine, generator and transfer case as a whole and install them on the vehicle frame.

[0046] In this embodiment, the second mounting module is disposed between the first mounting module and the second mounting module and is welded, and the second mounting module is fixedly connected to the mounting plate. A vibration damper is installed on the mounting plate to reduce resonance.

[0053] To facilitate installation and positioning, process holes are also provided on the left front mounting plate and the right front mounting plate for guiding and positioning when the drive component assembly is hoisted to the mounting platform, thereby further improving assembly accuracy and efficiency.

[0054] In this embodiment, the right front bracket and the left front bracket are both designed as L-shaped structures, and the rear bracket is designed as a T-shaped structure. The entire drive component is assembled through a combination of two L-shaped brackets and two T-shaped brackets, and is installed as a whole on the vehicle frame. The overall structure is conducive to reducing resonance, greatly improving the accuracy of engine installation, and reducing the cumulative tolerance of drive component assembly.

[0055] Embodiment 2

[0056] In another typical embodiment of the present invention, a method for installing a hybrid loader driving component mounting bracket is provided. The hybrid loader driving component mounting bracket according to the first embodiment includes the following steps:

[0057] After the engine is assembled, the left front bracket and the right front bracket are fixedly connected to the engine, and then the engine is placed on the transition platform;

[0058] Install two generators and a transfer case in sequence at the flywheel end of the engine, and connect the generator and the transfer case to the engine coaxially;

[0059] Install two rear brackets and hoist the drive component assembly onto the vehicle frame for installation.

[0060] Specifically, after the engine is assembled, the left front bracket and the right front bracket are installed on both sides of the front end of the engine by bolt connection, and the installed engine is hoisted onto the special tooling of the transition platform.

[0061] Two generators and a transfer case are installed in sequence at the flywheel end of the engine, and the generator and the transfer case are coaxially installed on the generator shaft at the flywheel end of the engine, thereby realizing coaxial connection between the engine, the generator and the transfer case.

[0062] Then, the two rear brackets are fixedly connected to the engine, generator and transfer case respectively by bolts, so as to complete the installation and fixation of the entire mounting bracket structure with the engine, generator and transfer case. Finally, the lifting points are hung on the lifting holes on the rear bracket and the engine respectively, and the assembled drive component assembly is installed on the vehicle frame. Among them, when the assembly is installed on the vehicle frame, a shock absorber can be installed at the connection of the left front bracket and the right front bracket respectively, and two shock absorbers can be installed at the connection of each rear bracket respectively. The overall arrangement of six shock absorbers effectively reduces the force and deformation of each shock absorber, and avoids the failure of the vibration reduction function caused by permanent deformation.

[0063] This embodiment adopts an integrated mounting bracket structure to fix the engine, generator and transfer case as a whole for hoisting, which effectively reduces the coaxiality deviation of the three, while reducing resonance and assembly cumulative tolerance, which is beneficial to extending the life of the entire machine.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that the present invention may have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
