[0022] The utility model is further described below in combination with the drawings and examples.

[0023] A typical embodiment of the utility model, such as Figure 1As shown, a loader force pump arrangement, including force pump 1, brake valve 2 and air tank 3, two force pump 1 is arranged side by side below the loader cab, brake valve 2 is arranged in the cab, brake valve 2 is installed on the brake pedal 4, brake valve 2 is controlled by brake pedal 4.

[0024] Air tank 3 is fixed below the loader cab, and is arranged opposite to the two force pump 1, the inlet of air tank 3 is connected to the air compressor pump through the air pipe, the outlet of air tank 3 is connected to brake valve 2 through the air pipe, the outlet of brake valve 2 is connected to the two force pump 1 through the two brake air pipe, the two force pump 1 is connected to the driver assembly on the front drive axle and rear drive axle through brake oil pipe.

[0025] Air compressor pump generates high pressure gas, and delivers high pressure gas to air tank 3, when braking is needed, step on brake pedal 4, brake valve 2 is turned on, high pressure gas enters two force pump 1 through brake valve 2, force pump 1 pushes brake fluid into brake assembly under the action of high pressure gas, so as to brake the wheels by brake assembly.

[0026] Because the size of the force of force pump 1 is affected by the air pressure, and then affects the size of the braking force, the two force pump 1 is arranged below the loader cab, which shortens the distance between the brake valve 2 located in the cab, avoids the distance between the two force pump 1 and brake valve 2 is too far, which leads to the loss of air pressure is too large, affects the brake performance.
