Description

Technical Field

[0001] This utility model relates to the field of automotive shock absorber technology, specifically an automotive shock absorber with noise reduction effect. Background Technology

[0002] The term "shock absorber" is a common term in the automotive chassis industry. An automotive shock absorber is actually a vibration damper. Shock absorbers are used not only in the suspension of automobiles but also in other locations. For example, they are used in the driver's cab, seats, steering wheel, and can also be used as a buffer in vehicle bumpers.

[0003] According to patent authorization announcement number CN116972095A, a noise-reducing automotive shock absorber is disclosed, relating to the field of automotive shock absorber technology. It includes a hydraulic cylinder, a damping spring, and a piston rod, with the piston rod movably engaged at the center of the top of the hydraulic cylinder. This invention controls temperature through the coordinated action of a heating component, a temperature control ring, and an airflow ring. When the hydraulic oil temperature drops below the normal operating temperature, the temperature control ring rotates, preventing heat from the heating component from dissipating into the external environment, thus maintaining the temperature of the hydraulic oil within the hydraulic cylinder. When the hydraulic oil temperature rises and exceeds the normal operating temperature, the temperature control ring rotates again, squeezing a rubber head. This causes the rubber head to move the piston within the mounting groove, thereby driving airflow within the airflow ring, achieving cooling and preventing abnormal shock absorber operation that could generate excessive noise, thus providing a better driving experience for the driver and passengers.

[0004] However, in existing automotive shock absorbers, the springs are mostly fixedly welded to the shock absorber. When the spring needs to be replaced, the welded joint must be separated, which damages both the welded joint and the spring, making the replacement work very inconvenient. At the same time, when the automotive shock absorber is exposed to cold temperatures, the low temperature will affect the viscosity of the hydraulic oil inside the shock absorber, causing the hydraulic oil to become more viscous. The more viscous hydraulic oil will hinder the movement of the piston rod and piston inside the working cylinder, resulting in greater noise during the shock absorption process, which will cause many inconveniences in use.
