Thu, 03 Nov 2016 08:00:00 EDTA shock absorber includes, an outer tube arranged in an outer circumference of the cylinder to form a cylindrical gap in conjunction with the cylinder to provide a twin-tube structure, a reservoir formed in the tank, a piston passage that allows only for a flow of the hydraulic fluid directed from the piston-side chamber to the rod-side chamber, an suction passage that allows only for a flow of the hydraulic fluid directed from the reservoir to the piston-side chamber, an discharge passage that allows the rod-side chamber to communicate with the reservoir, a damping valve provided in the discharge passage, and a connecting member that connects the outer tube and the tank. The discharge passage communicates with the reservoir via the cylindrical gap and the connecting member.
Thu, 03 Nov 2016 08:00:00 EDTA temperature-compensating damping element, which is suitable for the temperature-independent reduction of vibrations, which has a fixed, non-elastic outer part and a fixed, non-elastic inner part, which is either fully or partly inserted into a mating cut-out or opening of the outer part. The outer and inner parts have contact surfaces which are connected to one another by an elastic layer which comprises an elastomer material and which is, or can be, pre-tensioned with respect to a desired frequency by a tensioning element. The elastic layer which is responsible for the vibration damping is directly connected at one or more points to an additional elastic volume. The additional elastic volume is a multiple of the volume of the elastic layer, and has the effect that the excitation frequency of the damping element changes in the case of a temperature change within a temperature range.
Thu, 03 Nov 2016 08:00:00 EDTA system is disclosed comprising a carbon/carbon brake disk comprising a carbon fiber having a crystal orientation (CO) between 80% and 100% and a coefficient of friction of more than 0.183 in response to a rejected takeoff condition.
Thu, 03 Nov 2016 08:00:00 EDTA brake disc assembly including a brake disk ring, a bell and a connecting mechanism between the brake disk ring and the bell, wherein the connecting mechanism includes a form-locked and/or force-locked connecting element in an axial direction DO of the brake disc ring, the connecting mechanism comprises a bushing for the connecting element and a distance element arranged between the brake disk ring and the bell, wherein the bushing includes a shoulder and a loss prevention, wherein the bushing further includes a region A1 provided for the brake disk ring and a region A2 provided for the bell, wherein the region A1 has an average expansion E4 in an direction perpendicular to DO and the region A2 has an average expansion E2 in an direction perpendicular to DO.
Thu, 03 Nov 2016 08:00:00 EDTThe present invention discloses a brake drum, which relates to a drum-typed brake for vehicles. The brake drum comprises: a brake drum body, which comprises a mounting portion for connecting a wheel, a braking portion for engagement with a brake shoe, and a transitional connecting portion disposed between the mounting portion and the braking portion; one, two or more than two cracks disposed on the wall of the braking portion, wherein each crack begins at the end of the braking portion and ends at the transitional connecting portion; and a hoop device tightly mounted to the whole outer peripheral surface of the braking portion. Heat expansion stress and tension stress of the brake drum body are released into the cracks when braking, which reduces the probability that the brake drum body develops from longitudinal micro cracks to random multiple cracks and finally develops into fractures, which improves safety and extends service life. The disposition of the hoop device improves the tensile resistance strength and fatigue resistance of the brake drum body. The hoop device also applies a clasp force to the brake drum body, which avoids the danger of burst and flying out of the brake drum body and greatly improves service life and use safety.
Thu, 03 Nov 2016 08:00:00 EDTAn actuator drive, for blinds, roller shutters and the like, has a drive motor and a centrifugal brake. A rotational disk is coupled to a drive shaft of the drive motor via a shaft flange. Two centrifugal shoes are smoothly guided in the rotational disk. In the unpowered state, brake shoes of the centrifugal shoes engage, frictionally or in a positive-locking way on an outer surface of a friction ring fixed to the motor housing. Upon starting of the drive motor, the brake shoes release the friction ring. The radial displacement of the brake shoes is maintained until the drive motor comes to a stop, wherein the brake shoes 8 are drawn radially inward by spring elements and function again as a locking mechanism. The spring elements are pretensioned such that the brake shoes effect a sufficient retaining torque.
Thu, 03 Nov 2016 08:00:00 EDTThe invention relates to a damping device (100) for damping relative movements between a stay and a structural element of a civil engineering construction, comprising:—a viscoelastic first damping system (110) for damping a first relative movement component,—a second damping system (120) in series with the viscoelastic first damping system and for damping a second relative movement or component.
Thu, 03 Nov 2016 08:00:00 EDTThe present invention provides a movable end heads structure for synchronous braking, comprising an inner moving body, wherein top and bottom portions of the inner moving body are respectively provided with two active slots and two holes configured in an reverse staggered configuration. The holes and the active slots of the top portion enable brake cables and end heads thereof to be disposed therein. The holes and the active slots of the bottom portion enable control cables and end heads thereof to be disposed therein. The end heads of the brake cables move within the active slots of the top portion, and the end heads of the control cables move within the active slots of the bottom portion to pull any one of the control cables. When the two brake cables or both the two control cables are pulled simultaneously, the two brake cables are affected and pulled.
Thu, 03 Nov 2016 08:00:00 EDTAn apparatus a housing structure and a magnetic assembly. The magnetic assembly is configured to slide within the housing structure in a first direction associated with a direction of travel of the housing structure and in a second direction that is opposite of the first direction. The magnetic assembly includes a first pole plate having a first polarity and a second pole plate having a second polarity that is opposite of the first polarity.
