In a suspension bush in which an intermediate member is arranged between an inner shaft member and an outer tube member that are connected by a main body rubber elastic body, a central portion in the axial direction of the inner shaft member includes an inner bulging portion projecting toward the outer periphery, the outer tube member includes an outer curved portion concave toward the inner periphery, and the intermediate member includes an intermediate curved portion concave toward the inner periphery. The main body rubber elastic body is pre-compressed by diameter reduction of the outer tube member, an inclination angle of both axial end parts of the outer curved portion with respect to the axial direction is increased by diameter reduction of the outer tube member 14, and both axial end parts of the outer curved portion are pressed against axial end portions of the main body rubber elastic body.

A joint for a vehicle, the joint having an outer sleeve, a joint shell for receiving a movably supported joint inner portion, and an inner sleeve, at least part of which is arranged between the joint shell and the outer sleeve. The inner sleeve has two radially outwardly projecting rim cylinders which are axially mutually spaced and run around the outer periphery of the inner sleeve, and the two rim cylinders define a peripheral recess on the outer periphery of the inner sleeve. The joint is characterized in that a press-fit device designed integrally with the inner sleeve extends in the region of at least one rim cylinder of the inner sleeve radially outwards beyond the outer diameter of the rim cylinder.

A joint is formed between first and second workpieces. The first workpiece defines a cavity, while the second workpiece includes a shear member. The shear member is at least partially inserted into the cavity to secure the first workpiece to the second workpiece. One of the workpieces has a lower hardness and/or shear strength than the other workpiece and includes at least one shear tab with a base portion and an end portion. In inserting the shear member into the cavity, the end portion of the shear tab is broken away from the base portion, leaving the base portion to extend between the cavity and the shear member, thereby securing the first workpiece to the second workpiece.

A ball joint includes: a ball stud including a stud portion having one end portion connected to a structural member and another end portion, to which a ball portion is integrally joined; a housing made of metal and configured to support the ball portion to allow swinging and rotating movement of the ball portion; and a ball seat made of plastic and interposed between the housing and the ball portion. The ball seat includes a plurality of protrusions jutting out from the ball seat and inserted into a plurality of through holes formed in a bottom portion of the housing. The protrusions having pierced through the through holes are staked at their distal portions. The protrusion of the ball seat has a large diameter portion, whose diameter is larger than an inner diameter of the through hole, at its proximal portion proximal from the distal portion thereof.

A replacement ball joint assembly (10) adapted to be pressed into a previously used and possibly distorted receiving hole (26) in a suspension component such as a control arm (28). A socket housing (12) of the assembly (10) includes a plurality of generally annular, concentric knurls (36) each having a respective crest portion (38) and separated one from another by intervening relief grooves (40). The crest portions (38) of the knurls (36) may be tapered so as to provide a lead-in feature to minimize misalignment during a press-in installation operation. The knurls (36) are preferably softer than the control arm material so that they yield during press-in rather than further disfiguring or enlarging the receiving hole (26). Displaced material from the crest portions (38) of the knurls (36) flows into the relief grooves (40).

A top mount assembly includes an insulator comprising an upper plate, a lower plate, and a rubber bushing accommodated in an accommodation space defined between the upper plate and the lower plate; and a strut bearing comprising an upper housing, a lower housing, and a bearing interposed between the upper housing and the lower housing and configured to rotate the lower housing relative to the upper housing. The upper housing of the strut bearing may comprise an insulator mounting part formed on an upper portion of the upper housing and on which the insulator is mounted, the insulator mounting part may comprise a lower plate mounting part on which the lower plate of the insulator is mounted and an upper plate supporting part formed outside the lower plate mounting part, and the upper plate support part may be configured to support a lower surface of the upper plate.

A rotation lock is provided to a piston rod, a collar is fitted on a small-diameter portion disposed on an end portion on a side of the piston rod extending from a cylinder, and the collar is press-fitted onto a press-fitted portion disposed on the piston rod by a press-fitting jig screwed with an external thread formed on the small-diameter portion. The press-fitting jig adds an axial force to the collar.

An air spring connecting device for mounting an air spring strut on a vehicle may include an air spring support bearing having a head bearing receiver, a head bearing having at least one cylindrical outer surface, and a piston rod that is axially guided through the head bearing and is sealed in an airtight manner relative to the head bearing. The head bearing may be positioned in the head bearing receiver of the air spring support bearing positioned coaxially relative to the piston rod. An airtight connection may be formed between the head bearing receiver and the head bearing. A press connection element may be positioned in direct contact with the head bearing receiver and the head bearing. A sealing element may be positioned in a region of the head bearing receiver between the air spring support bearing and the head bearing.

The invention relates to a chassis component with a structural part which comprises at least one strut section with an open cross-section shape, wherein in an end area of the strut section a first wall section and a second wall section are formed, the first wall section has a first joint-receiving opening and the second wall section has a second joint-receiving opening. The two joint-receiving openings are arranged opposite one another, and a joint housing of a joint is arranged in the two joint-receiving openings. In order to improve the arrangement of an additional component, in particular a sensor element, on the chassis component and make it simpler and/or less costly, the said additional component is fixed between the two wall sections and on the joint housing by means of a clamping fit and/or a press fit.

[Object] Damage to a surface of a resin bush caused by press-fitting is prevented even when a configuration for positioning during welding is added. [Solving Means] A rolled collar (40) is a steel rolled collar into which a resin bush (90) is pressed-fitted, and which is joined to a joining member by welding. The rolled collar includes a main body part (50) formed in a hollow cylindrical shape, and a clinch part that joins both end surfaces of the main body part together by fitting. The rolled collar includes a notch part (70) formed by cutting off a portion of an annular edge (53) in the main body part. Here, a convex jig determining a position of the main body part at a time of welding is fit into the notch part. The rolled collar includes a cavity part (80) formed to be hollow from an inner circumferential surface side on a wall surface around the notch part to form a clearance (81) between the press-fitted resin bush and an edge portion (71) of the notch part on the inner circumferential surface side.
