Embodiment 1

[0013] Such as figure 1 As shown, a skid steer loader trailer system includes a closed hydraulic system 1, the closed hydraulic system 1 includes a hydraulic pump 2 and a hydraulic motor 3, and also includes a trailer valve 4, which includes a communication position and cut-off position, the trailer valve 4 is connected to the oil inlet and outlet of the hydraulic motor 3, and the trailer valve 4 is in the cut-off position by default, and the trailer valve 4 is an electric control valve.

Embodiment 2

[0015] Such as figure 2 As shown, a skid steer loader trailer system includes a closed hydraulic system 1, the closed hydraulic system 1 includes a hydraulic pump 2 and a hydraulic motor 3, and also includes a trailer valve 4, which includes a communication position and cut-off position, the trailer valve 4 is connected to the oil inlet and the oil outlet of the hydraulic motor 3, and the trailer valve 4 is in the cut-off position by default.

[0016] The trailer valve 4 is a hydraulic control valve, and the closed hydraulic system 1 also includes an oil charge pump 5. The oil of the oil charge pump 5 passes through the one-way valve 6, and the control solenoid valve 7 is connected to the hydraulic control valve of the trailer valve 4. chamber, and an accumulator 8 is provided between the one-way valve 6 and the control solenoid valve 7. The control solenoid valve 7 includes a communication position and a cut-off position, which is a cut-off position in the case of no electri...

Abstract

The invention discloses a trailer system of a skid loader. The trailer system comprises a closed hydraulic system, wherein the closed hydraulic system comprises a hydraulic pump and a hydraulic motor. The trailer system further comprises a trailer valve, wherein the trailer valve comprises a conduction position and a cutoff position, is connected to an oil inlet and an oil outlet of the hydraulic motor and is located at the cutoff position in default. According to the trailer system of the skid loader, the traction in the case that the whole machine is non-powered is simply realized through additionally arranging the trailer valve in a closed hydraulic traveling system of the skid loader.

Description

technical field [0001] The invention relates to a trailer system of a skid steer loader, which belongs to the technical field of engineering machinery. Background technique [0002] The skid steer loader is a flexible and compact loader. It is called a skid steer loader or a skid steer loader because it relies on skid steer. The walking system of the skid steer loader adopts a closed hydraulic system. The system means that the return oil of the hydraulic motor is sucked away by the hydraulic pump. The hydraulic pump and the hydraulic motor form a closed loop. When the closed hydraulic travel system of the skid steer loader fails or the engine fails, it is often necessary The faulty skid steer loader is towed to the repair site for repair. However, at present, none of the skid steer loaders is equipped with a trailer system, so that the tires and the ground sliding hydraulic motor are subjected to a large force during traction, which is likely to cause secondary failures. C...
