A stabilizer bushing installed on a stabilizer bar is made of two divided parts of rubber or the like to prevent or decrease generation of a gap in a bonding surface. The stabilizer bushing installed on an outer periphery of the stabilizer bar by adhesion includes divided rubber bushings of an upper rubber bushing and a lower rubber bushing. Before adhesion, both end portions of the upper and lower rubber bushings, respectively, in a circumferential direction are tapered so that an overlapping amount between the upper and lower rubber bushings increases toward the outer periphery side of the bushings. After adhesion, a bonding surface is bonded by pressure

An end turn portion of a coil spring includes a first portion, a second portion, and a third portion. The first portion is always in contact with a spring seat irrespective of the magnitude of a load applied to the coil spring. The second portion contacts the spring seat when the load applied to the coil spring is large, and is separated from the spring seat when the load is small. The third portion is always separated from the spring seat irrespective of the magnitude of the load. An insulating sheet made of a material having rubber elasticity is attached to a lower surface of a wire at the end turn portion by means of adhesive bonding. The insulating sheet is provided on a lower surface of a region including at least the second portion.

The disclosure relates to a longitudinal leaf spring device for suspension of a body of a motor vehicle. and the longitudinal leaf spring device comprises a longitudinally formed leaf spring element and a coupling device that mechanically couples the leaf spring element to a motor vehicle axle. According to the disclosure, a holder device is provided that has a base holder element for fixed connection to a vehicle chassis and a suspension adjustment element that faces the leaf spring element and is fixedly connected to the base holder element. In this case, the leaf spring element is connected in a front region, fixedly to the base holder element, and the front region is provided to come into mechanical bearing with the suspension adjustment element in at least one operating state.

A stabilizer manufacturing apparatus is adapted to bond a rubber bush, which is a bush made of rubber disposed between a stabilizer and a vehicle body, to a rubber bush bonding location where an adhesive layer of the stabilizer is formed. The stabilizer manufacturing apparatus is provided with: a curing furnace for heating the stabilizer, which is conveyed by a manufacturing line conveying unit and has the rubber bush bonding location with which the rubber bush is press-contacted, and performing the bonding; a heat source device that heats air; a blower device that sends the air heated by the heat source device as hot air; and a plurality of nozzles that are disposed along the manufacturing line conveying unit in the curing furnace and blow the hot air against, at a near position from, a location in the vicinity of the rubber bush bonding location of the stabilizer.

A stabilizer bar with rubber bush includes a stabilizer bar (2), and at least one rubber bush (6) adhesively fixed to at least a portion of the stabilizer bar. The stabilizer bar (2) and the rubber bush (6) are adhesively fixed to each other with an adhesive agent layer (3). The adhesive agent layer (3) includes a primer agent layer (4) formed on a surface of the stabilizer bar (2) and having a dry film thickness of 3 m or more and 13 m or less; and a first top coat agent layer (5) formed on the primer agent layer (4) and having a dry film thickness of 5 m or more and less than 13 m.

An induction heating device according to one embodiment includes a first coil portion and a second coil portion. A bar-shaped workpiece is placed between the first coil portion and the second coil portion. The first coil portion includes a pair of first narrow pitch portions formed in respective end portions thereof, a first wide pitch portion formed between the first narrow pitch portions, and a first medium pitch portion formed in the center. The second coil portion includes a pair of second narrow pitch portions formed in respective end portions, a second wide pitch portion formed between the second narrow pitch portions, and a second medium pitch portion formed in the center.

It is herein described an oscillating arm for a motor-vehicle suspension having a first rod element and a second rod element. The second rod element is a half-shell rod that provides a cavity. The oscillating arm also comprises at least one insert, made of plastic or fiber-reinforced composite material, which fills the cavity of the half-shell rod.

An assembly is provided consisting of a frame element of a motor vehicle and a connecting element used for connecting a part. The connecting element is secured to the frame element by way of a fiber winding.

In order to reduce both the weight and the production costs in the case of vehicle chassis components consisting of at least two parts, a first part is made as a sheet component by press hardening and the second part is produced by a conventional production method, which does not include press hardening. The part produced by press hardening forms a structural component, whereas the other component serves to stiffen the part produced by press hardening.

An air spring component includes at least two parts, which have corresponding joining areas. The joining areas are connected to one another in an adhesive-bonded manner in an inert atmosphere. The air spring component can be a rolling piston, a supplementary volume container for the rolling piston or an air spring pot.
