摘要： A damper housing disposed on a center axis includes an extended mains section and a narrowed end section. The narrowed end section has a second predetermined wall thickness less than the first predetermined wall thickness of the extended main section. An intermediate conical section, connecting the narrowed end section and the extended main section, has an intermediate conical section wall thickness equal to the second predetermined wall thickness at an internal inclination angle relative to the center axis. A method for manufacturing the damper housing using a preformed tube, a first broaching die, a calibrating mandrel, and a swaging die is performed by compressing the preformed tube between the first broaching die and the narrowed head of the calibrating mandrel and compressing the preformed tube between the swaging die and the intermediary section of the calibrating mandrel to form the narrowed end section and the intermediate conical section, respectively.

摘要： An assembly for magnetically dynamic damping useful for isolating vibrational forces includes a housing wall bounding a main chamber therein. The assembly further includes a fixed magnetic source disposed in the main chamber. A diaphragm of elastic material is disposed in the assembly impermeably dividing the main chamber into sub-chambers. The diaphragm includes a magnetically actuated element adjacent to the fixed magnetic source. A source of electrical current energizes the magnetically actuated element, the fixed magnetic source, or both and either repels or pulls the magnetically actuated element with respect to the fixed magnetic source. A magnetic guide surrounds the fixed magnetic source and defines a gap exposing the fixed magnetic source to the magnetically actuated element. The magnetic guide routes the magnetic field towards the gap and prevents outward magnetic interference to the rest of the assembly.

摘要： Disclosed is a motor vehicle twin-tube damper comprising: a tube filled with a working liquid, a piston assembly disposed slidably inside the tube divides the tube into a rebound chamber and a compression chamber. A compensation chamber is located outside of the tube. A base valve assembly including a rebound valve assembly and a compression valve assembly controls the flow of the working liquid between the compensation chamber and the compression chamber. The rebound valve assembly includes a number of rebound flow channels covered by a main deflective disc. To suppress vibrations generated by the deflective disc due to pressure fluctuations occurring during rapid changes of the damper stroke direction, the rebound valve assembly includes an additional deflective disc disposed over the main deflective disc and separated from it by an annular gap with a thickness (G) that is less than the thickness of the main deflective disc.

摘要： A hydraulic damper assembly including a housing that extends about and along an axis and defines an interior wall and a chamber for holding a fluid. A piston assembly is disposed in the chamber and axially moveable therein. The piston assembly includes a core. A wear band is disposed about the core and has an inside surface and an outside surface. The inside surface of the wear band defines at least one groove in fluid communication with the chamber for allowing the fluid to bias the wear band toward the interior wall of the housing during the passage of the fluid though the at least one groove during movement of the piston assembly.

摘要： 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.

摘要： A control system for an active powertrain mount includes a control signal which is based on the input velocity of the chassis at the active powertrain mount. The control signal may be proportional to the input velocity or to the mount velocity, which is the difference between the input velocity of the chassis at the active powertrain mount and the output velocity of the powertrain component at the active powertrain mount. The input velocity of the chassis at the active powertrain mount may be determined by a controller based on the CG heave and the roll and pitch velocities of the chassis. The output velocity of the powertrain component at the active powertrain mount is determined by the controller by integrating an acceleration signal from a component accelerometer disposed on the powertrain component proximate to the active powertrain mount. Corresponding methods for controlling an active powertrain mount are also provided.

摘要： A damper assembly (20) is disclosed, and it comprises: a first rube (22) defining an inner surface (24) extending along an axis (A) to define a fluid chamber (30) containing a damping fluid (32); a rod (34) extending axially in the first rube (22); a guide (40) annularly disposed about the rod (34) and engaging the first tube (22); a piston (42) and a retainer (46) which are attached to the rod (34) and are slidably disposed in the first tube (22); a first spring (50) engaging and extending axially away from the retainer (46); a valve body (52) which is disposed adjacent to the first spring (50) and has a periphery (54) spaced from the inner surface (24) of the first tube (22) to define an annular channel (60); a second spring (66) extending axially away from the valve body (52); a bumper (68) engaging the second spring (66). The valve body (52) moves into sealing engagement with the retainer (46) in response to the bumper (68) engaging the guide (40). This causes the damping fluid (32) to move exclusively through the valve body (52) providing additional damping force.

摘要： The invention provides for a brake pad apparatus for connecting to a brake assembly of a motor vehicle. The brake pad apparatus includes a backing plate that extends along a first plane and has an inside surface and an outside surface. A liner is connected to the inside surface of the backing plate for contacting the rotor for creating a frictional force against the rotor to slow the motor vehicle. An insulating layer is connected to the outside surface of the backing plate for providing heat and noise insulation during contact of the liner against the rotor. At least one projection extends from the outside surface of the backing plate through the insulating layer, and past the insulating layer for being engaged by a pressing member of the brake assembly for compressing the liner against the rotor of the brake assembly.

摘要： In shock absorber system 10, solenoid 18 varies the damping force by changing the position of spring seat 24, and the effective preload force, at the same time. In the normal, de-energized condition (with no current), damping forces are generated by the piston valve 30 including piston 20. The actuated valve spring 16 is relaxed and set in such a way that it applies only a minimum preload force to the rebound-side disc stack 28. The motion of the plunger 14, pin 32 and movable spring seat 24 assembly changes the spring force by varying the distance between the movable spring seat 24 and the stationary spring seat 22. In the energized state, applying current to coil 12 generates a pulling force on the plunger 14 in the direction of the core element 34 to attract plunger 14 towards the core 34 and across the initial gap 36 until it is in a direct contact with the core's surface 38. Maintaining plunger 14 at this position requires applying a continuous constant holding current to coil 12 so that the position of the plunger is preserved (and the high preload force at the same time). When current is no longer applied to the coil 12, then the pulling force is no longer generated, and the plunger assembly returns back to the original (soft) position due to the reverse action of the valve spring 16.
摘要翻译：在减震器系统10中，螺线管18通过改变弹簧座24的位置和有效的预载力同时改变阻尼力。在正常的断电状态（没有电流）时，包括活塞20的活塞阀30产生阻尼力。致动的阀弹簧16被松弛和设定，使得其仅对最小的预紧力施加到柱塞14，销32和可动弹簧座24组件的运动通过改变可动弹簧座24和固定弹簧座22之间的距离来改变弹簧力。在通电状态下，施加电流线圈12沿着芯元件34的方向在柱塞14上产生拉力，以将柱塞14朝着芯34吸引并穿过初始间隙36，直到其与芯的表面38直接接触。将柱塞14保持在该位置需要对线圈12施加连续恒定的保持电流，使得保持柱塞的位置（并且同时具有高的预紧力）。当电流不再施加到线圈12时，则不再产生拉力，并且由于阀弹簧16的反作用，柱塞组件返回到原始（软）位置。
