Description

Technical Field

[0001] The utility model relates to the field of filling magnetorheological fluid for shock absorbers, in particular to a stirring and liquid supplementing mechanism for magnetorheological fluid of shock absorbers. Background Technique

[0002] The stirring and liquid supplementing mechanism for magnetorheological fluid of shock absorbers is a supporting device for filling magnetorheological fluid of shock absorbers. The magnetorheological shock absorber utilizes electromagnetic reaction and makes real-time responses to road conditions and driving environments based on the input information from sensors monitoring the movement of the vehicle body and wheels. The magnetorheological fluid is a magnetic soft particle suspension. After the fluid is injected into the electromagnetic coil in the shock absorber piston, the magnetic field of the coil will change its rheological characteristics, so as to generate a damping force with rapid reaction and strong controllability in the case of no electromechanical control valve and simple mechanical device. With the continuous development of technology, people's requirements for the manufacturing process of the stirring and liquid supplementing mechanism for magnetorheological fluid of shock absorbers are also getting higher and higher.

[0003] The existing liquid supplementing mechanism for magnetorheological fluid of shock absorbers has certain drawbacks when in use. First of all, the existing liquid supplementing mechanism for magnetorheological fluid of shock absorbers cannot conveniently and quickly perform automatic liquid supplement control during use. Manual liquid supplement is prone to overfilling or underfilling, which brings certain adverse effects to the actual use process. For this reason, we propose a stirring and liquid supplementing mechanism for magnetorheological fluid of shock absorbers. Content of the Utility Model

[0004] Technical problems to be solved: Aiming at the deficiencies of the prior art, the utility model provides a stirring and liquid supplementing mechanism for magnetorheological fluid of shock absorbers. After an oil barrel filled with magnetorheological fluid is placed on the fixed frame to be stirred manually, the stirring mechanism is installed above the oil barrel and fixed through the hoisting mechanism above the fixed frame manually. Then, nitrogen is filled and low-speed stirring is started. After stirring evenly, the liquid pumping pump group pumps the magnetorheological fluid into the filling oil barrel until the electronic floor scale below the filling barrel shows that the filling amount is satisfied and then stops. Nitrogen is filled until the nitrogen pressure value reaches the requirement and then stops and stirring starts. The liquid pumping pump group then pumps the magnetorheological fluid from the filling barrel into the specified container. The liquid supplement oil barrel detects the liquid level through the liquid level sensor in the barrel and timely notifies the operator to replace the empty oil barrel for liquid supplement, which can effectively solve the problems in the background technique.

[0020] As Figures 1-4 shown, the shock absorber magnetorheological fluid stirring and replenishing mechanism includes a movable integral bracket 1, a stirring fixed bracket 2, and a nitrogen gas storage tank 9. An electronic floor scale 10 is fixedly installed at the bottom of the stirring fixed bracket 2. A stainless steel oil barrel 12 is arranged on the electronic floor scale 10.
