A multi-plate spring suspension of composite material for a vehicle includes: a first bracket unit mounted to a rubber spring; a second bracket unit mounted to a trunnion base; and a plurality of composite springs manufactured by impregnating reinforcing fibers with resin, coupled to the first bracket unit and the second bracket unit at opposite ends thereof, respectively, and being vertically spaced apart from each other.

An equalizer for a suspension system includes a pivot arm pivotably connected to first and second plates at a pivot point, first and second bump stops connected between the first and second plates on one side of the pivot point, and third and fourth bump stops connected between the first and second plates on the other side of the pivot point. First through fourth shock absorbers are disposed between the pivot arm and the first through fourth bump stops, respectively.

A longitudinal leaf spring device for suspending a motor vehicle body or chassis on a vehicle axle thereof. Leaf spring device including an elongated leaf spring unit, a coupling device connecting the leaf spring unit to the vehicle axle, and suspension unit arranged in a substantially vertical direction between a chassis and the axle. The suspension unit including suspension elements providing a spring-back force in the vertical direction and producing an active connection between the chassis and the axle when the distance between the chassis and axle exceeds a predetermined first deflection depth.

An axle suspension for a vehicle includes a spring assembly with a leaf spring and a connecting arm, wherein the leaf spring supports a vehicle axle and, on an end side, is pivotably connected to a vehicle structure and pivotably connected to the connecting arm. In order to provide an optimized axle suspension with two-stage suspension, the spring assembly in a region of the connecting arm has a first stop element and the vehicle structure has a second stop element, which stop elements under normal load of the vehicle are spaced apart from one another and, when a limit load is exceeded, contact one another, whereby at least one stop element is elastically deformable.

A clamp group for a vehicle leaf spring suspension is disclosed. The clamp group secures a longitudinally disposed, leaf spring at separate and distinct locations, between which the leaf spring is undamped and spaced away from the top and bottom pads of the clamp group. Shear stress is reduced and the spring remains active throughout its length.

Provided is a robot leg structure that includes a link extending downward from a leg joint, a ground contact portion that comes in contact with a ground, a leaf spring that couples the link and the ground contact portion to each other, and a damping member adjacent to the leaf spring and couples the link and the ground contact portion to each other. With this configuration, the damping member damps the vibration attributed to the leaf spring, making it possible to reliably stabilize the motion of the legs of a robot.

A leaf spring for a vehicle. The vehicle has a drivetrain that generates a high frequency vibration that is transmitted into an interior compartment of the vehicle and has a volume that can be heard by a driver and/or passenger. The leaf spring has a primary leaf and a secondary leaf that extends along and underneath the primary leaf. The leaf spring also has a high frequency dampener that is located between the primary and secondary leafs and is spaced apart from a tip liner insert. The high frequency dampener reduces the volume of a high frequency vibration that is present in the interior of the vehicle to a value less than an objectionable level to an occupant during operation of the vehicle. Therefore, the high frequency vibration is not heard by the driver and/or occupant.
