However, at present, the swing axle of loaders at home and abroad still adopts the rigid contact between the axle and the frame (such as figure 1 As shown), when the vehicle is driving on an uneven road surface, the road surface will have a great impact on the whole machine, and the axle of the loader will tilt, which will easily cause the instability of the vehicle body and increase the fatigue and fear of the driver, thereby affecting the stability of the vehicle. , comfort, service life of vehicle components and driving safety all have a greater impact

Embodiment Construction
[0014] like figure 2 , 3 As shown, when the loader is running on an uneven road, if the wheel at the left end of the axle encounters an obstacle (or the right end encounters a mud pit) and is lifted, the piston rod of the left piston cylinder 8 installed on the upper left of the axle 2 will be compressed , the volume of the working chamber 13 decreases and the internal oil pressure rises. In this state, the oil in the working chamber of the left end oil cylinder quickly drains oil to the oil storage chamber 12 through the circulation check valve 16 at the bottom. Simultaneously, the piston rod of the piston cylinder 8' installed on the right upper part of the axle 2 will be stretched, the volume of the working chamber 13 will increase, and the internal oil pressure will decrease. In this state, the oil in the oil storage chamber of the right piston cylinder will The vehicle frame is balanced by replenishing oil to the working chamber 13 through the compensating check valve 1...

A hydraulic damping balanced swing axle used for a loader belongs to the technical field of loader structures. Its structural feature is that a tripod is installed in the lower middle part of the loader frame, and a shaft hole is formed in the lower center part of the tripod, which is hinged with the shaft hole in the middle part of the axle through a pin shaft. It is connected with the ends of the piston rods of the left and right piston cylinders, and the lower ends of the left and right piston cylinders are respectively connected with the axle by bolts. The structure of the left and right piston cylinders is composed of a double-layer cylinder body to form an oil storage chamber and a working chamber. On the lower part of the inner wall of the double-layer cylinder, there is a circulation check valve that can only flow the oil from the working chamber to the oil storage chamber. Oil flows from the oil storage chamber into the compensation check valve of the working chamber. An oil injection hole is formed on the outer wall of the cylinder body, and a vent hole is formed on the top cover of the piston cylinder. The advantage is that the hydraulic damping balance device is used, which has a good buffering effect, reduces the impact vibration, increases the stability of the loader, and prolongs the service life of the parts.
Description
technical field [0001] The invention belongs to the technical field of loader structure design, and in particular relates to a hydraulic damping balanced swing axle for a loader. Background technique [0002] In recent years, with the rapid development of the construction machinery industry, higher requirements have been put forward for the improvement of construction vehicle structure technology and safety and comfort. However, at present, the swing axle of loaders at home and abroad still adopts the rigid contact between the axle and the frame (such as figure 1 As shown), when the vehicle is driving on an uneven road surface, the road surface has a great impact on the whole machine, and the axle of the loader is tilted, which is likely to cause instability of the vehicle body and increase the fatigue and fear of the driver, thereby affecting the stability of the vehicle. , comfort, service life of vehicle parts and driving safety have all brought a greater impact.
