In addition, an inner supporting step for supporting the inner side of the coil spring and an outer supporting part for supporting the outer side of the coil spring are formed on the inner side of the spring seat part.
The spring pad for an automotive suspension system is characterized in that an upper portion of the inner support jaw is provided with a fixing jaw for fixing the coil spring so as to prevent the coil spring from coming off the upper portion of the spring seat.
The spring pad for a vehicle suspension device is formed on the upper surface of the protruding portion so as to increase the contact area with the coil spring to reduce frictional force to prevent slippage and to prevent rubbing. do.
Further, a spring pad for a vehicle suspension device is provided, wherein an inner circumference of the discharge portion is formed to be higher than an outer circumference, and is formed in a tilted structure.
The spring pad may include a fixing protrusion formed on the bottom surface of the spring pad so as to be attached to the lower pad. The fixing protrusion may be formed integrally with the bottom surface of the spring pad, Spring pad for device.
According to the present invention constructed and operative as described above, it is not necessary to insert a steel material (steel insert), the thickness can be remarkably reduced, and a lightweight spring pad can be provided.
In addition, durability is improved by the elasticity and rigidity of the bottom surface and the side surface of the spring pad according to the present invention, and the defective product generated in the manufacturing process can be crushed and reused due to thermoplasticity, The time is shortened and the productivity is improved.
