Abstract

The present invention provides a bounce limiter for a suspension device, the bounce limiter is made of foamed polyurethane, does not produce unpleasant noise caused by friction, and is used for the suspension of vehicles with shock absorbers and coil springs The cylindrical elastic body on the device allows the piston rod to pass through the central hole (47), and at the same time, the upper end (60) is fitted and retained in the concave fitting part of the spring seat in an embedded state, so that when the vehicle bounces and shock absorption The outer peripheral surface (70) of the axial lower end surface (65) and the lower end portion (52) of the bounce limiter (46) made of foamed polyurethane that is elastically abutted against the cylinder of the device is made Formed into a wrinkle-forming surface (68) composed of fine concavo-convex groups.

Description

technical field

[0001] The present invention relates to a bounce limiter for a suspension device. The bounce limiter is a cylindrical foamed polyurethane bounce limiter used for a vehicle suspension device having a shock absorber and a coil spring as constituent elements. It relates to a bouncing limiter characterized in the technical means of preventing noise. Background technique

[0002] Conventionally, in a suspension device of a vehicle including a shock absorber and a coil spring as constituent elements, a bounce limiter that abuts against a cylinder of the shock absorber during a bounce to limit excessive contraction displacement of the shock absorber is used.

[0003] The bounce limiter has a cylindrical shape as a whole, and is mounted such that the piston rod of the shock absorber is inserted into the center hole.

[0004] The bounce limiter, when the vehicle is bouncing, its lower end abuts against the cylinder of the shock absorber and undergoes compression and ...
