A suspension element of a vehicle includes a coil spring, and a bearing part provided with a main stop. The spring is mounted on the bearing part in such a manner that a first end of the spring comes to bear against the main stop. The bearing part includes a secondary stop placed in front of the main stop, against which secondary stop the first end of the spring bears during a method for assembling the suspension element. The secondary stop is capable of moving away under the effect of pressure exerted by the spring on the secondary stop during a stage of compressing the spring after the spring has pivoted about the spring's rotational axis during a stage involving straightening the spring, so that a second end of the spring is made to interact with a centering element, in order to come to bear against the main stop.

A suspension thrust bearing device for use with a suspension spring in an automotive suspension strut of a vehicle. The device provides a bearing having upper and lower annular bearing members in relative rotation, lower bearing member having a lower cup having at least one protruding indexation element. The device also provides a damping element made of resilient material and interposed between the lower cup and the suspension spring. The indexation element is made of a different material than that of the lower cup, the lower cup being made of a rigid plastic material and the indexation element being made of a resilient material.

A spring pad for a suspension can satisfy both conflicting dynamic seating property and durability, and unification of specifications. In particular, the spring pad may include: a body portion disposed on one side of a spring to support the spring; and an insert portion embedded inside of the body portion and integrally formed with the body portion. The spring is seated on an inclined surface of the body portion, and the inclined surface may be formed in a spiral shape gradually increasing in height. A spiral curve of the inclined surface may be formed by reflecting a composite line minimizing a gap between the inclined surface and the spring.

A spring guide includes: a base portion configured to support a coil spring; and an opening portion provided so as to penetrate through the base portion, the opening portion being configured such that a shock absorber is inserted into the opening portion, the opening portion is provided with: protruded portions protruding out from an inner circumferential surface of the opening portion, the protruded portions being configured to support the shock absorber; and a recessed portion recessed in the inner circumferential surface of the opening portion, a plurality of the protruded portions are arranged along a circumferential direction of the opening portion, and a gate trace of an injection mold is formed in the recessed portion.

A vehicle strut assembly includes a boot and a coil spring. The boot has a vertical wall, a spring receiving portion and a centering portion projecting from the vertical wall. The coil spring has an end section, a transition section and a main section, the end section being fitted to the spring receiving portion encircling at least a portion of the vertical wall and defining a first radially inner diameter. The transition section has an increasing inner diameter extending from the end section to the main section. The main section defines a second radially inner diameter greater than the first radially inner diameter. The centering portion is positioned to contact a radially inner surface of the transition section of the coil spring restricting movement of the end section of the coil spring relative to the spring receiving portion of the boot.

A suspension coil spring device may include a compression coil spring (10) that has a coating film, a rubber vibration isolator, and an adhesive layer that joins the compression coil spring and the rubber vibration isolator to each other. The adhesive layer is a cured product of a hot melt adhesive that melts at 80° C. to 100° C. A softening point of the hot melt adhesive is lower than a heat-resistant temperature of the coating film. The softening point of the hot melt adhesive is lower than a heat-resistant temperature of the rubber vibration isolator.

A spring guide attached to a shock absorber, the shock absorber being provided between a vehicle body and a wheel, the spring guide being configured to support a coil spring for elastically supporting the vehicle body, and the spring guide includes: a main body portion formed of a resin material; and an elastic part provided between the main body portion and an end portion of the coil spring, the elastic part is formed of a material having elastic modulus lower than the material forming the main body portion, the elastic part being integrally molded on the main body portion.

A spring apparatus (10), including: a spring (12); an elongated object (18A) disposed within and along the spring (12); and a mode-changing assembly (16), for providing a first mode in which a portion (38) of the spring (12) being along the elongated object (18A) is not springy, and a second mode in which an entire of the spring (12) is springy.

A suspension includes a coil spring, a shock absorber, a spring seat, and at least three strongly pressing parts. The coil spring elastically receives vertical movement of a wheel relative to a vehicle body. The shock absorber damps the vertical movement. The spring seat is provided in the shock absorber. The sprint seat supports an axial end of the coil spring. The coil spring is in direct or indirect contact with the spring seat over a predetermined distance from an end to a point of separation of the coil spring. The strongly pressing parts are provided in the spring seat. The strongly pressing parts apply contact pressures higher than contact pressure applied by other part, to the coil spring. The point of separation is disposed at a region that is between the strongly pressing parts and has the largest opening angle about an axial center of the shock absorber.

A suspension coil spring device includes a compression coil spring that has a coating film, a rubber vibration isolator, and an adhesive layer that joins the compression coil spring and the rubber vibration isolator to each other. The adhesive layer is a cured product of a reactive hot melt adhesive.
