The second transverse plate 16 can be used to install a direct-connected radiator 91 to dissipate heat from the engine 2.

[0036] In addition, one side of the first transverse plate 15 is connected and fixed to the vertical plate 11 on the same side, and the other side of the first transverse plate 15 not connected to the vertical plate 11 is provided with a connecting plate 151, and the upper and lower sides of the connecting plate 151 are both protruding from the first transverse plate 15. Figure 8The first transverse plate 15, the vertical plate 11 connected to the first transverse plate 15 and the enclosure plate 151 can form an "I"-shaped structure to increase the structural strength of the first transverse plate 15 so that its strength can meet the vibration conditions when the engine 2 is running, ensuring the normal operation of the loader.

[0037] Thus, using the frame 1, refer to Figure 5 , the direct-connected radiator 91, the engine 2 and the upper assembly 3 on the loader can be distributed transversely at the rear of the frame 1; in this way, the rear space of the frame 1 can be fully utilized to make the overall structure of the loader compact. At the same time, the engine 2 and other components are arranged at the rear of the frame 1, so that the counterweight 8 can be designed to reduce weight while ensuring the same tipping moment as the traditional fuel loader, thereby reducing the operating weight of the entire machine. The manufacturing cost of the counterweight 8 is reduced accordingly. The reduction in the operating weight of the entire machine can effectively reduce the fuel consumption of the entire machine. And a higher tipping load can also be achieved.

[0044] like Figure 4 The direct-connected radiator 91 is installed on the second horizontal plate 16, and is located at the cooling fan of the engine 2, for water cooling or intercooling the engine 2, and the cooling fan of the engine 2 dissipates heat for the direct-connected radiator 91, so as to dissipate heat for the engine 2 in time.

[0045] like Figure 3 and Figure 5 The capacitor box assembly 4 is mounted on the second mounting support 17, and the capacitor box assembly 4 is electrically connected to the upper motor 32 through the upper controller 41; the engine 2 drives the upper motor 32 in the upper assembly 3 to generate electricity, and then controls the upper controller 41 to transmit high voltage electricity to the capacitor box assembly 4.

[0046] like Figure 4 and Figure 5 A mounting plate 51 is provided at the bottom of the hydraulic oil tank 5 , and the mounting plate 51 is used to mount the third mounting area 18 .

[0047] Specifically, two hydraulic pipelines 52 are installed between the hydraulic oil tank 5 and the reduction box 31, and two hydraulic pumps 53 are provided on the reduction box 31 and are respectively connected to the two hydraulic pipelines 52; the two hydraulic pumps 53 can be a working pump and a steering pump, and the reduction box 31 drives the two pumps to work, suck oil from the hydraulic oil tank 5, and supply the working device and steering oil.

[0048] The engine 2 drives the upper motor 32 to generate electricity while also driving the reduction box 31. The reduction box 31 drives the hydraulic pump 53 to extract the hydraulic oil in the hydraulic oil tank 5 and supply the front end working device of the loader.

[0050] like Figure 6 and Figure 7 The drive assembly 6 includes a drive motor 61 and a gearbox 62; the drive assembly 6 is installed between the two vertical plates 11 at the head of the frame 1; the drive motor 61 is electrically connected to the capacitor box assembly 4 through a drive controller 63; the drive motor 61 is connected to the gearbox 62, and the gearbox 62 is connected to the drive axle 7, which is installed at the lower middle of the frame 1. The high voltage electricity in the capacitor box assembly 4 is transmitted to the drive assembly 6 through the control of the drive controller 63. The drive controller 63 controls the drive motor 61 to transmit the power to the drive axle 7 through the gearbox 62 to drive the vehicle.

[0051] like Figure 5 A counterweight 8 is also installed below the rear end of the frame 1.

[0052] In summary, a loader of the utility model has the following advantages:

[0053] 1. The engine 2, hydraulic box, upper assembly 3, hydraulic pump 53 and other components are placed at the rear of the frame 1, which is equivalent to moving the weight backward and increasing the torque. Therefore, while ensuring the same tipping torque as the traditional fuel loader, the counterweight 8 can be designed to reduce weight, thereby reducing the operating weight of the whole machine. The manufacturing cost of the counterweight 8 is reduced accordingly. The reduction in the operating weight of the whole machine can effectively reduce the fuel consumption of the whole machine.

[0054] 2.Higher tipping load can be achieved at lower machine operating weight.

[0055] 3. The hydraulic oil tank 5 is moved back close to the engine 2, which is beneficial to increase the tipping moment and to prevent the hydraulic pump 53 from sucking air and causing too much pressure loss.

[0056] 4. The daily maintenance parts of the engine 2 (oil filter, machine filter, air filter, etc.) and the hydraulic pump 53 are arranged at the rear of the vehicle, which is more convenient for inspection and maintenance.

[0057] 5. The cooling system uses an independent radiator 92 + a direct-connected radiator 91. The independent radiator 92 can be placed according to the spatial position of the whole machine, and is less affected by the spatial position. The fan speed can be adjusted according to the load of the whole machine to reduce the energy consumption of the whole machine. The volume of the direct-connected radiator 91 in the horizontal layout of the engine 2 can be made small and does not affect the rear view of the whole machine. However, the direct-connected radiator 91 in the vertical layout of the traditional engine 2 is large in volume and has a great impact on the rear view of the whole machine.

[0058] 6. The hybrid loader's engine 2 is arranged horizontally, which is compact and does not affect the maintenance space. The length of the whole machine is at least 500mm shorter than the traditional engine 2 vertical arrangement.

[0059] In this embodiment, some parts such as the engine 2 and the upper assembly 3 are shown in simplified form.
