Description

Technical Field

[0001] The present application relates to the field of air suspension structures, and more specifically, to an air suspension structure for new energy vehicles. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source (or use conventional vehicle fuels and adopt new vehicle-mounted power devices), integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. Today's cars are all equipped with suspension structures. Suspension is the general term for all force-transmitting connection devices between the frame and the axle, axle or wheel of the car. The main function of suspension is to transmit all forces and moments acting between the wheel and the body, such as supporting force, braking force and driving force, and to mitigate the impact load transmitted to the body by uneven roads, attenuate the vibration caused by this, ensure the comfort of the passengers, and reduce the dynamic load of the cargo and the vehicle itself.

[0003] In the existing air suspension structure, after the two adjustment sliders are fixed with bolts and nuts, there is a line contact between the adjustment sliders and the bolts. After long-term use, the circular surface of the bolts will be worn, causing the connection between the components to become loose, and the service life of each component will be reduced. Therefore, an air suspension structure for new energy vehicles is needed to assist in solving this problem. Utility Model Content
