Description

Technical Field

[0001] The utility model relates to the technical field of automobile springs, in particular to a spring for automobile shock absorption. Background Art

[0002] Existing automotive shock-absorbing springs are primarily used to improve vehicle comfort and stability. Typically installed in a car's suspension system, they serve two primary functions: 1. Shock absorption: When a car travels on uneven roads, the springs absorb the impact of the ground, reducing the force transmitted to the vehicle and passengers; 2. Vehicle stability: Springs help maintain good contact between the wheels and the ground, enhancing wheel grip and, consequently, improving vehicle handling and stability.

[0003] However, when it is used, it has poor adaptability and the spring system cannot be adjusted according to different driving conditions or load requirements, which may lead to insufficient performance in some cases and fail to provide additional support and stability when needed, such as when driving at high speeds or with heavy loads, which may affect the overall performance and safety of the vehicle. Utility Model Content

[0004] The purpose of the present utility model is to solve at least one of the technical problems existing in the prior art, and to provide a spring for automobile shock absorption, which can drive the screw to rotate through a motor, thereby driving the sleeve to descend, so that the two connecting plates are connected together, and the slave spring is connected to the upper load-bearing plate. At this time, the device is changed from a double-spring shock-absorbing structure to a four-spring shock-absorbing structure. When the double-spring configuration is supported, it is usually used under daily driving conditions. This configuration provides sufficient shock absorption and comfort and is suitable for driving on ordinary roads. When the four-spring configuration is supported, it is used when the vehicle load increases (for example, loading or towing heavy objects). The four-spring configuration can provide additional support, reduce the shaking of the vehicle body, and improve driving stability, thereby improving the overall driving experience and safety. The double-spring or four-spring mode can be selected according to actual needs to optimize the driving experience and vehicle performance.
