摘要： A coupled torsion beam axle (CTBA) bushing is press-fitted into a bushing bracket provided at a tip of a trailing arm at each of two opposite sides of a CTBA suspension system. In particular, the CTBA bushing includes: an outer pipe including a through-hole formed therein; an inner pipe positioned in the through-hole; and a bushing rubber disposed in the through-hole and positioned between an outer peripheral surface of the inner pipe and an inner peripheral surface of the outer pipe, in which the bushing rubber includes: first compounds extending in a first direction, which is a diameter direction of the inner pipe, with the inner pipe interposed therebetween; and a second compounds integrated with the first compounds and extending in a second direction, which is perpendicular to the first direction, with the inner pipe interposed therebetween.

摘要： A bushing for a trailing arm may include an inner rod having a plate shape, a body in which a central portion of the inner rod is disposed, a reinforcing material disposed to surround an outer surface of the body, a first elastic member in which the reinforcing material is disposed, a second elastic member disposed around the first elastic member, and an outer steel member disposed to surround the first elastic member and the second elastic member. The reinforcing material may be disposed between the outer surface of the body and an inner surface of the first elastic member.

摘要： A mounting bushing for a vehicle satisfies durability requirements as well as performance, such as ride comfort, handling, and noise, vibration, and harshness (NVH) reduction. The mounting bushing includes an inner pipe, an elastic portion surrounding an external side of the inner pipe, an intermediate pipe surrounding an external side of the elastic portion and having a cutout provided in an axial direction, and an outer pipe surrounding an external side of the intermediate pipe. The elastic portion is formed of a material having a dynamic ratio lower than a dynamic ratio of a rubber material.

摘要： A hydraulic mount in which a fluid for supporting an engine of a vehicle is sealed, includes a core configured to receive vibration from outside, an insulator molded on the external side of the core, and a diaphragm spaced at a predetermined distance from the insulator, wherein a fluid is sealed between the insulator and the diaphragm, and an upper chamber and a lower chamber are provided between the insulator and the diaphragm by a nozzle assembly. The nozzle assembly includes an upper nozzle located adjacent to the upper chamber, a lower nozzle coupled to the upper nozzle and located adjacent to the lower chamber, and a membrane located between the upper nozzle and the lower nozzle.

摘要： A hydraulic bushing of a lower arm for a vehicle includes an inner pipe, an outer pipe, an elastic member disposed between the inner and outer pipes and connecting the inner pipe to the outer pipe, and a fluid chamber defined in the elastic member. Fluid is sealed inside the fluid chamber. A stopper protrudes radially from an outer circumference of the inner pipe toward the outer pipe. The elastic member is coupled to the stopper such that the elastic member surrounds the stopper.
