Abstract

Disclosed is a protective tube for a coil spring of a vehicle suspension device. The protective tube includes a cut-out portion through which the coil spring is fitted therein. The cut-out portion has a pair of upper and lower outwardly protruding wings. The wings are joined to each other by high-frequency welding. The protective tube prevents foreign materials from entering the cut-out portion. In addition, the protective tube is easy to manufacture by molding.

Description

technical field [0001] The present invention relates to a protection tube for a coil spring of a vehicle suspension device, and more particularly, to a protection tube formed with a cutout portion formed by a wing, through which a coil spring of a vehicle suspension device is installed in the protection tube to Prevent the entry of foreign objects and achieve better durability. Background technique [0002] In general, a suspension device installed on a vehicle absorbs the shock applied to the wheels during driving to protect the driver and other interior devices of the vehicle from vibration while providing comfort to the driver. [0003] Leaf springs or coil springs have been used in suspensions. In particular, coil springs are installed on most passenger cars. In view of this situation, much research and development has been carried out on coil springs for vehicle suspension devices. [0004] figure 1 is a schematic diagram of an exemplary vehicle suspension device ac...
