[0002] The chassis double rocker structure is a common automobile chassis suspension system design, which involves the connection between the engine and the frame. In automotive engineering, the number of rocker arms is usually related to the performance of the engine, because more rocker arms mean more valves, which can improve the performance of the engine. The double rocker structure is usually stronger and more powerful than the single rocker structure. The chassis double rocker structure is an important automobile chassis design element, which plays a key role in improving the performance and driving experience of the vehicle. Whether it is a motorcycle or a car, the double rocker structure is an effective solution for achieving efficient energy transfer and vehicle stability. The main components of the chassis double rocker structure include rocker arms, stabilizer bars and connecting mechanisms.

[0003] After a motor vehicle has been running for a period of time, the wheel hub needs to be injected with lubricating oil to reduce the friction between the wheel axle and the wheel hub. In the prior art, most chassis double rocker arm structures are not equipped with an automatic wheel hub oiling mechanism. Oiling requires manual oiling or driving the vehicle to a repair shop for oiling, which reduces the convenience of using the motor vehicle. At the same time, if the wheel hub is not oiled for a long time, it will cause damage to the wheel axle or wheel hub, affecting the use of the motor vehicle. Utility Model Content

[0008] As a further description of the above technical solution:

[0009] A reinforcing rib is fixedly connected between the two rocker arms.

[0010] As a further description of the above technical solution:

[0011] One end of the oil extraction pipe away from the water pump passes through one side of the oil storage box, one end of the oil inlet pipe away from the water pump passes through the interior of the wheel hub, and the oil inlet pipe is connected to the fixed shell.

[0012] As a further description of the above technical solution:
