An additional spring for a shock absorber of a motor vehicle and a damper bearing for a shock absorber of a motor vehicle. In this case, the additional spring includes a first spring body which has a central hole for guiding through a piston rod of the shock absorber. The first spring body is formed spherical on an end face. The damper bearing according to the invention comprises a cylindrical receptacle space in which the first spring body of the additional spring is retained at least in certain regions, and is distinguished in that the receptacle space has a spherically formed base surface formed corresponding to the end face of the first spring body.

A shock absorber includes a first end fitting connected to a first telescoping member, a second end fitting connected to a second telescoping member, the first and second telescoping members being telescopically mounted relative to each other. An elastomeric spring/damper is disposed between the first telescoping member and the second telescoping member.

A vibration damper of a vehicle wheel is supported on a vehicle body by a damper mount having an elastic body. The vibration damper includes a fluid-filled cylinder, a piston guided in the cylinder, and a piston rod. A wherein a damper chamber is formed in the cylinder on each side of the piston. The damper mount includes a hydraulic pressure chamber connected via a fluid-conducting connection to the damper chambers, whose volumes are respectively reduced when the vehicle wheel is deflected in relation to the vehicle body. In addition, a throttle valve is provided in the fluid-conducting connection, wherein the throttle value comprises a valve body that is displaceable in relation to a valve seat counter to a spring force, and a throttle bore.

An air spring includes a closing member, a rolling piston, and an air spring bellows connected to the rolling piston and the closing member to form a fluid-filled pressure chamber. A level control system for supplying and/or discharging fluid may be integrated into the pressure chamber to control level position based on air spring stroke. The level control system may have a control valve and an actuator connected to the control valve. The actuator may include a guide tube coupled to the rolling piston or closing member, and movably arranged within the pressure chamber. An actuating member may include a pin member and may operate the control valve. A compression spring may have a central spring and a biasing spring, and the guide tube may include a control flange coupled to the pin member, and the biasing spring may be supported to press the pin member against the control valve.

Disclosed herein is a spring preload system comprising a cylinder with an outer diameter, a body to house at least the cylinder, a piston shaft, and a main damping piston. The main damping piston is coupled to the piston shaft and configured for operation within the cylinder. The main damping piston is further configured to divide the cylinder into a compression side and a rebound side. The spring preload system further comprises a preload cylinder and a valve that is fluidly disposed between the compression side and the preload cylinder.

Suspension bumper for the suspension of a motor vehicle, comprising a molded part made of elastomer being essentially symmetrical in revolution about a main axis of compression, this bumper comprising one end forming a crown comprising bearing faces (48) designed to receive pressure from a moving part, the end crown comprising protuberances (58, 60) that are separated from one another by notches (54) distributed over the perimeter of this crown, these bosses having bearing faces (48) arranged at various heights.

The disclosure concerns a spring assembly with a leaf spring. The leaf spring extends in a vehicle longitudinal axis, supports a vehicle axle and is connected at least indirectly to a vehicle superstructure at a front end and at a rear end. In order to provide a wheel suspension with advantageous springing and damping behavior that is optimized with regard to weight and complexity, according to the disclosure it is provided that at least one damping region, which is at least partially fluid-filled, is integrated in the leaf spring.

The present invention relates to a hydraulic damper for a motor vehicle, comprising a tube with a slidably piston assembly attached to an end of a piston rod that is led outside the tube through a rod guide. A protective cap surrounds a portion of the tube. A partially axially elastic protective tube is attached to the cap and surrounds it and the piston rod. The cap is a unitary plastic component and has an annular flange provided with locking means attaching it to the protective tube. The cap has a plurality of spaced axial ribs separated by axial slots and joining a cylindrical section of the cap with the flange. A plurality of auxiliary ribs join the axial ribs and the annular area of the axial slots is larger than the total annular area of the axial ribs and the auxiliary ribs combined.

A inverted type shock absorber, comprising: an outer cylinder; a damping cylinder including a cylinder body and a piston rod, wherein the cylinder body is coaxially sleeved within the outer cylinder; at least three bearings which are fixed at different upper-lower positions of an internal surface of the outer cylinder to support the external surface of the cylinder body such that the cylinder body is slidable against the outer cylinder along the expanding-compressing direction; and an rubber stabilizer which tightly surround the external surface of the cylinder body in such a manner that the rubber stabilizer is sandwiched between two of said at least three bearings such that the rubber stabilizer provides the cylinder body a stabilizing force which radially retains the cylinder body relative to the outer cylinder to stabilize the sliding between the outer cylinder and the cylinder body.

A spring rubber seat provided between a spring formed by winding a wire rod to elastically support a chassis and a spring seat where the spring is placed. The spring rubber seat includes an arc seat portion having a seat surface where the spring is seated; and a link portion that links one circumferential end with the other circumferential end of the seat portion to make the spring rubber seat in an annular shape.
