INSULATOR OF SUSPENSION

摘要

The present invention discloses an insulator of a suspension, which stably performs a supporting function and improves a vibration and isolation function by improving the performance of the rubber of an insulator. The insulator of the present invention comprises a supporting member (140), which is installed in a main plate (110) fixed to a vehicle body (1) and has a piston rod (21) of a strut (20) fixed thereto; a bearing plate (120) for supporting a bearing (121); a first supporting unit (151), which is inserted between the main plate (110) and the supporting member (140); an insulator rubber (150), which has a second supporting unit (152) extended from the first supporting member (151) in order to be located between the main plate (110) and the bearing plate (120); and a reinforcement plate (160), which reinforces the strength of the second supporting unit (152) by being installed in the second supporting unit. The modulus coefficient (K2) of the second supporting member is structured to be larger than the modulus coefficient (K1) of the first supporting member (151).
