A thrust bearing for suspension systems includes an upper element, a lower element, a bearing disposed between the upper element and the lower element, a primary sealing part and a secondary sealing part. The upper element includes a circumferentially formed contact surface with a joining point. The primary sealing part contacts the upper element and the lower element in an outer opening formed on a radial outside of the bearing. The primary sealing part has a joining surface joined to the contact surface and an area increase element joined to the joining point. The secondary sealing part contacts the upper element and the lower element in an inner opening formed on a radial inside of the bearing.

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 strut assembly includes a piston rod of a shock absorber, an upper support of the shock absorber, a bearing, a spring and a buffer block, which are coaxially arranged. The upper support of the shock absorber has a first through hole, the bearing has a second through hole, and a portion of the upper support of the shock absorber is arranged in the second through hole, the buffer block has a third through hole, and one end of the piston rod of the shock absorber is located in the first through hole, the other end of the piston rod of the shock absorber passes through the third through hole, the buffer block is connected with the upper support of the shock absorber, the spring is sleeved around the piston rod of the shock absorber, and the spring is connected with the bearing. The present disclosure further provides a vehicle.

A hydraulic mount apparatus includes a housing defining a cavity. The apparatus also includes an annular member disposed in the cavity. The annular member is secured to the housing to split the cavity into a first chamber and a second chamber. The apparatus further includes a pressure relief apparatus coupled to the housing. The pressure relief apparatus is configured to allow fluid communication between the first and second chambers in response to a predetermined pressure threshold being reached in at least one of the first and second chambers. A suspension system including a shock absorber and a link is coupled to the shock absorber. The suspension system further includes the hydraulic mount apparatus coupled to one of the shock absorber and the link.

A RevoKnuckle-type suspension for a wheeled vehicle has a hub mounted to a bearing carrier for rotation relative thereto about a steering axis, and a shock absorber connected non-rotatably to the bearing carrier. The shock absorber has an outer cylinder having an axially-extending guide hole defined therein, and a piston and attached piston rod retained for axial reciprocation in the guide hole. The guide hole and at least one of the piston and the piston rod retained therein have respective complementary-shaped, non-circular cross-sectional shapes which engage one another to resist axial rotation of the piston and/or the piston rod within the guide hole. The carrier is therefore restrained against rotation relative to the vehicle sprung structure without the need for any additional component(s) such as a control arm or stabilizer, as required in a traditional RevoKnuckle-type suspension.

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 present invention provides a steering system for an in-wheel motor vehicle capable of controlling driving torques and speeds of in-wheel motors mounted in left and right wheels to be different from each other at the time of curve driving of the vehicle to generate a steering angle of the wheel for the curve driving, and performing a steering angle control of sensing the generated steering angle and fixing the steering angle to a desired steering angle.

A strut mount and bearing assembly includes a strut mount having upper and lower ends, a central bore for receiving a shock absorber end and an annular upper race surface between the upper and lower ends and extending circumferentially about the bore. The upper end is fixedly connectable with a vehicle body and has a flat attachment surface disposeable against a vehicle surface of the vehicle body. A first bearing race is disposed on the mount and a spring seat having a second bearing race is movably coupled with the strut mount. The seat also has a lower end with spring engagement surface and a second bearing race is disposed on the seat spaced axially from the first bearing race. Rolling elements are disposed between the first and second bearing races to form a bearing. The various components are formed and sized to make an axially compact assembly.

Annular joint surfaces of a lower case of a strut bearing device respectively have case-side projections that project in an axial direction. Shapes A of the case-side projections, seen in an axial direction, continue in a circumferential direction, and vary their position in a radial direction along the circumferential direction. An inner-diameter side seal has a seal-side recess fitted to the case-side projection. An outer-diameter side seal has a seal-side recess fitted to the case-side projection.

In a strut bearing device, an upper spring seat made of steel has a cylindrical part and a disc part. The cylindrical part has, at an upper part thereof, an engagement hole penetrated in a radial direction. A lower case of a strut bearing has a cylindrical member fitted along an inner peripheral surface of the upper part of the cylindrical part. The cylindrical member has, at its outer peripheral surface, an engagement projection that is engaged with an engagement hole. Relative movement of the upper spring seat and the lower case in an axial direction and in a circumferential direction is restricted in a state where the engagement projection is engaged with the engagement hole.
