Description

Technical Field

[0001] The utility model belongs to the field of buffer control, and particularly relates to a walking buffer control mechanism for agricultural machinery tires. Background Technique

[0002] The principle of tire walking buffer mainly depends on the work of the buffer. By absorbing and dispersing the impact force caused by the uneven road surface, the vehicle vibration is reduced, and the continuous contact between the wheel and the ground is maintained.

[0003] The working principle of the buffer is based on the basic principle of fluid mechanics and mainly consists of several core parts such as a piston, a piston rod, an oil cylinder, and damping oil. When the vehicle is driving on an uneven road surface, the up and down movement of the wheel is transmitted to the piston through the piston rod, and the piston moves in the oil cylinder. In this process, the damping oil is forced to flow through the small holes on the piston, and the resistance generated by this flow effectively absorbs the impact energy and converts it into heat energy and dissipates it. Specifically, when the wheel encounters a bump, the piston moves downward, the oil pressure in the oil cylinder increases, forcing the damping oil to flow upward through the throttle hole on the piston, generating resistance and absorbing the upward kinetic energy of the wheel. On the contrary, when the wheel encounters a depression, the piston moves upward, and the damping oil is forced to flow downward through the throttle hole, also generating resistance and absorbing the downward kinetic energy of the wheel. This mechanism effectively reduces the vibration and impact during vehicle driving and improves the driving smoothness and comfort.

[0004] In the existing buffer, the amount of damping oil in the oil cylinder is fixed, and the maximum buffer force is fixed. When large agricultural machinery is walking, due to the large body weight and large variation in the loading amount, and at the same time the road conditions are complex, it is necessary to adjust the maximum buffer force according to the road conditions and the body weight to adapt to different road conditions. Therefore, it is necessary to provide a walking buffer control mechanism for agricultural machinery tires. Content of the Utility Model

When the stop valve is opened, the oil circuit block communicates the filling and discharging joint and the oil cylinder joint, and the filling and discharging of the damping oil in the oil cylinder are realized by controlling the opening and closing of the stop valve.

[0008] Optionally, a pressure gauge is provided on the oil circuit block, and the pressure gauge measures the pressure of the damping oil in the oil circuit block.
