Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A hydromount absorbs and alleviates vibration of driving components such as an engine, a power train, a transmission, and the like of a vehicle, and more particularly, to a three point supporting hydromount in which inner pipes are disposed in a horizontal direction of a vehicle frame.

Abstract: An air-damped engine mount may include a main pipe, a main rubber into which a center bolt is fitted, a cover plate having at least an air hole, wherein the cover plate is coupled to a lower portion of the main pipe and the main rubber is coupled to an upper portion of the main pipe to form a damping chamber enclosed by the main rubber, the main pipe and the cover plate, and a membrane mounted on the cover plate to be displaced in response to a deformation of the main rubber.

Abstract: A pneumatic active engine mount has a middle fluid chamber and a pneumatic chamber inside an orifice module using a pneumatic plate. The orifice module divides an inner space in which working fluid is encapsulated into an upper fluid chamber and a lower fluid chamber. A change in the air pressure of the pneumatic chamber causes a change in the pressure of the middle chamber to thereby introduce a flow of working fluid between the upper fluid chamber and the middle fluid chamber. Various frequencies of vibration in an engine of a vehicle are reduced, and in particular, engine vibration in a middle-to-idling range is actively reduced.

Abstract: The inner circumferential surface of through holes in a metal plate is chamfered or put to anchor fabrication and a thermoplastic resin is injection molding to the inner circumferential surface of the through hole thereby forming a resin portion over the entire surface of the through hole and the resin portion is removed by grinding while leaving the peripheral portion of the resin portion thereby forming a polished work holding hole. Thus, when a resin portion is formed to the inner circumference of the holding hole in a polished work holder comprising a metal plate, the production is high and the cost is reduced, and the resin portion is not detached from the bonding portion with no use of the adhesive.
