  • Patent number: 10295028
    Abstract: A linear actuator provides linear displacement of an actuator plate. The linear actuator includes a set of base flexures that extend from a base plate to an actuator plate and a set of arm flexures that extend from a base arm to an actuator arm. The base arm of the base frame extends up perpendicularly from the base plate and the actuator arm, of the actuator frame, extends perpendicularly from the actuator plate. A base frame and actuator frame may be elbows that are arranged to form a box with the base flexures and arm flexures extending orthogonally within the cavity of the box. A flexure may include an extension element such as a pleated portion of the flexure that has stored length that enables the flexure to extend to increase the linear displacement region. The arm flexures prevent the base flexures from following a radius of motion.

  • Patent number: 9505390
    Abstract: A brake-assist device for a motor vehicle having a servomotor is described. A servomotor has a plunger piston, a moving part, and an arrangement to move the moving part into position with respect to the plunger piston. The servomotor is actuated by a control rod. The control rod has a first end that presses upon the plunger piston and a second end to receive a force exerted by a brake pedal intended to be moved by a driver of the vehicle. The servomotor includes a sensor interposed in a contact space between the plunger piston and the moving part. A spring is compressed between the plunger piston and the moving part. The servomotor includes an arrangement for displacing the plunger piston in the contact space based on the driving mode. A stiffness of the spring is sufficiently high for an onset of braking to occur only with a striking force that is significantly higher during a reactive driving mode than it is during a calm driving mode.

  • Publication number: 20130049273
    Abstract: A fiber reinforced plastic spring which enables prevention of breakage caused by compressive stress is provided. The FRP spring 1 has a laminated structure (reference numeral 20 in case of three-layer structure, reference numeral 30 in case of five-layer structure) having plural fibers which are different from each other in tensile modulus of elasticity and are laminated. An upper surface of the FRP spring 1 is a surface to which pulsating bending load is applied. An upper side region of each laminated structure 20 and 30, which is upper with respect to the neutral axis S, is a compressive stress region at which compressive stress is generated. A lower side region of each laminated structure 20 and 30, which is lower with respect to the neutral axis S, is a tensile stress region at which tensile stress is generated. Distribution of tensile modulus of elasticity of each laminated structure 20 and 30 is asymmetric with respect to the neutral axis S.

  • Patent number: 8365882
    Abstract: A spring for a composite brake disk. The spring has a planar central region with a hole and two spring regions which are formed symmetrically to one another and which in each case on sides lying opposite one another adjoin the planar central region. The spring regions in each case have an arc and a spring arm. Preferably, the spring arms have in each case an end region with a rounded bearing surface. By such a spring being used, a simple construction of a composite brake disk is made possible, the occurrence of hotspots and the effect of thermal rubbing being as far as possible avoided. At the same time, a functionally appropriate fit of the spring is ensured, the load on the pot due to the bearing surface of the spring being kept extremely low.

  • Publication number: 20130001845
    Abstract: A leaf spring made of a fiber composite material having integrated bearing holes and a method for producing is disclosed. The method comprises the steps of cutting prepreg strips of a predetermined length from a prepreg strand, removing cut-outs from the particular prepreg strip in the axial ends where a bearing hole should be formed, laying a plurality of prepreg strips one over the other in a prepreg stack in alternation so that the surfaces of the prepreg strips are flush to form a raw leaf spring forming a bearing hole by deforming an axial end of the prepreg stack in a plane perpendicular to the longitudinal extension (L) and perpendicular to the transverse extension (B) of the prepreg stack, setting the raw sheet spring to form the finished leaf spring in a mold with a suitable setting pressure and a suitable setting temperature.

  • Publication number: 20120318574
    Abstract: A complex wave spring, or Beer Spring™, for electrically coupling opposed electrical contact surfaces or generating a relatively constant force. The spring includes a first wave portion shaped to define a first upward undulation and a first downward undulation, and a second wave portion fixedly arranged relative to the first wave portion. The second wave portion is shaped to define a second upward undulation proximate to the first downward undulation, and a second downward undulation proximate to the first upward undulation. The spring may be formed of electrically conductive material suitable for electrically coupling electrical contact surfaces when the spring is in contact between the surfaces. The complex spring provides unusually constant spring forces over a relatively wide range of compression distances.
