Title:
DAMPER RUBBER SPRING STRUCTURE FOR LEAF SPRINGS
Document Type and Number:
WIPO Patent Application WO/2022/108130
Kind Code:
A1
Abstract:
The present invention comprises a damper rubber spring structure in which a support plate (41) is fixed by means of a first bolt (44) or a second bolt (45) onto one side of the upper surface of a lower leaf spring mass (30) in a space between the rear ends of an upper leaf spring mass (20) and the lower leaf spring mass (30), a pair of left and right square rings (42) are fixed to the left and right ends of the support plate (41), respectively, and a rubber rod (43) is supported so as to be movable forward/backward and left/right within the pair of left and right square rings (42). Accordingly, the present invention can absorb large shocks and vibrations generated when a small cargo truck or the like is driven on an unpaved road, a road with a lot of puddles, a speed bump, or the like and, at the same time, reduce rolling of a vehicle body, thereby making it possible to reduce fatigue during driving as well as promoting safe driving such as increasing the lifespan of a shock absorber installed on a rear wheel side and reducing cutting of leaf springs.
