The present invention relates to a coil spring pad for a vehicle suspension system, comprising: an accommodating groove (51) in which a lower end portion of a coil spring (10) is inserted and accommodated; and a pad extension part (55) which is formed from a first surface (35) of an upper surface (33) of a coil spring pad (31) and covers the whole section, except for a convexly raised portion and a through hole (73) of a lower seat (71), thereby preventing horizontal deformation of the coil spring pad (31).

A suspension device for vehicles (a front suspension (10)) is disclosed in which, of connecting portions (23, 24) of a lower arm (20) and a tie rod (6) for connection to a knuckle (35), one of the connecting portions (24) which is close to the rear of the vehicle is offset inward in the vehicle width direction with respect to the other connecting portion (23) which is close to the front of the vehicle, in the steering neutral state. The center (P2) of a lower end portion of a coil spring (60) is offset outward in the vehicle width direction and rearward in the vehicle's longitudinal direction with respect to the center (P1) of an upper end portion of the coil spring (60).

A spring cup for a primary suspension of a rail vehicle, wherein the spring cup has a longitudinal axis and a spring base for transmitting occurring forces onto a chassis frame of the rail vehicle, and includes a spring seat for receiving at least one spring element, wherein the spring seat is supported against the spring base of the spring cup, where a central section of the spring seat is formed as a contact element having a contact surface for an emergency spring device, and the spring seat is configured such that a force acting on the contact surface is introduced into the spring base outside of the projection surface, resulting from the projection at least of the contact surface along the longitudinal axis onto the spring base in order to achieve a transfer of force from the center of the spring base.

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 spring guide includes: a mounting portion formed so as to be depressed, the rubber sheet being fitted to the mounting portion; and a plurality of lock pieces formed to stand at an outer periphery of the mounting portion. At least one of the plurality of the first lock pieces and the second lock piece is disposed at a position that restricts deformation of a circumferential end portion of the rubber sheet to an outside in a radial direction, in a state where the rubber sheet is fitted to the mounting portion.

A suspension controller includes a target current setting unit configured to set a target current value, a current limitation setting unit configured to set a current limitation value, a current detector configured to detect a current value of a first current supplied to a solenoid that is configured to control a damping force of a suspension, a duty ratio setting unit configured to set a duty ratio based on the target current value, based on the current limitation value, and based on the current value detected by the current detector; and a current outputting unit configured to supply the solenoid with a second current that corresponds to the duty ratio set by the duty ratio setting unit and to a power supply voltage. The current limitation setting unit is configured to change the current limitation value based on the duty ratio set by the duty ratio setting unit.

The present invention relates to a coil spring pad for a vehicle suspension system, comprising: an accommodating groove 51 in which a lower end portion of a coil spring 10 is inserted and accommodated; and a pad extension part 55 which is formed from a first surface 35 of an upper surface 33 of a coil spring pad 31 and covers the whole section, except for a convexly raised portion and a through hole 73 of a lower seat 71, thereby preventing horizontal deformation of the coil spring pad 31.

The invention relates to a spring support for a coil spring (15), comprising an annular receiving element (5) having a top side and a bottom side, wherein the top side is provided to receive one end of the coil spring (15), and comprising an annular damping element (3), which is in contact with the bottom side of the receiving element (5), wherein the damping element (3) furthermore has on its inside a collar which extends from the bottom side of the receiving element (5) in the direction of the coil spring (15), and wherein the collar is formed by bending from a disk-shaped basic form of the damping element (3). The invention furthermore relates to a method for producing a spring support according to the invention, in which a disk-shaped damping element (3) is first of all placed in a casting mold, and an annular receiving element (5) is then produced by being molded or injection-molded to the damping element (3), with the result that the bottom side of the receiving element (5) is in contact with the annular damping element (3).

A dual bearing strut assembly for a vehicle suspension system includes a strut with a shock absorber comprising a damper cylinder and a piston rod, and a coil spring disposed around the shock absorber. The damper cylinder may be affixed to a knuckle of a vehicle wheel assembly and the piston rod may be affixed to a top strut mount. An upper bearing assembly and a lower bearing assembly are included. The coil spring has an upper end seated to the upper bearing assembly and a lower end seated to the lower bearing assembly. The lower end of the coil spring freely rotates about the damper cylinder when the coil spring is compressed thereby reducing torque on the damper cylinder and reducing bump steer of the vehicle steering system.
