Bearing for power train assembly in motor vehicle - has two hydraulic damping chambers interconnected by magnetic valve in passage through separator for torque support

A transverse torque support is constituted by two vertically spaced cantilever arms (12, 13) between which the bearing (11) consists of two fluid-tight vulcanised rubber buffers (15, 16) connected to an annular housing (17). The space (19) between the buffers (15, 16) is filled with bubble-free anti-freeze and divided into two chambers (21,22) by a sepg. plate (20). A passage (27) between the chambers (21,22) is opened by a magnetic valve (26) only when the power train is not in operation. ADVANTAGE - Damping effect of torque support is protected automatically against influences of loads on bearing, at low cost.

Automotive engine resilient mounting - has chambers filled with damping material between resilient buffers and support and interconnected

The resilient mounting is particularly for an automotive engine, having a support transmitting the load and guided between two stops, acting via rubber buffers against the latter. The buffers (6,7) are so fitted onto the support (4) as to enclose between it and the chambers (16,17) filled with a damping fluid or mass. The chambers are interconnected via a narrow overflow drilling in the support. On the sides of the buffers towards the stops (1,2) bosses can be formed, distorting progressively, typically lip-type edges round their end faces.

Flexible, damping mount, in particular for the drive engine of a motor vehicle

Flexible damping mount, in particular for the drive engine of a motor vehicle. The mount has an engine-fastening element (supporting element 7) and a body-connecting part (supporting element 7'), which are connected to each other by means of at least two spring elements (rubber elements 1, 1') and enclose with the latter two separate cavities. The cavities are in each case divided by a separating element (3, 3'), provided with at least one overflow opening (4, 4'), into two variable chambers (5, 6, 5', 6'), which are filled with fluid. In this way, two vibrational mount units are formed, which have in their dynamic spring rate on the one hand an absorption frequency and on the other hand a resonance frequency. Due to the connection of the two mount units, the absorption frequency and the resonance frequency are superimposed, so that an approximately constant dynamic spring rate is achieved for the mount over a relatively great frequency range. ...

DUAL SPRING RATE DAMPER

A damper has a piston having an axis, an outer surface, and opposing ends. Elastomeric seals are in sealing contact with the outer surface of the piston, the seals being coaxial with the piston and limiting movement of the piston to a path along the axis of the piston. The seals also define fluid chambers adjacent the ends of the piston. A primary passage communicates the fluid chambers, and a selectively switchable valve for controls a flow of fluid from one of the chambers to another of the chambers through the primary passage. When the flow of fluid through the primary passage is permitted, movement of the piston is resisted by a first spring rate due to a shear force required to cause shear deflection of the seals. When the flow of fluid through the primary passage is restricted, movement of the piston is resisted by a second spring rate due to a fluid force required to cause bulging deflection of the seals.

The controllable mount (106) may include a housing (108), a pin (120), rheological fluid (116) within the housing (108) and coils (131) provided proximate to the rheological fluid (116).

Rate-activated helmet suspension

Impact energy absorbing devices, in some embodiments, may be configured as a helmet having suspension elements employing “rate activated tethers” (RATs), a speed-sensitive flexible strapping material. The RATs are configured to suspend a helmet shell on the head of a wearer, so that impact to the helmet causes extension of the RATs. The RATs provide for: (1) steady force over long strokes, and (2) a stroke force that increases with increasing impact velocity. Standard impact testing of a helmeted headform shows that the RAT suspension decreases head accelerations by 50% relative to a standard suspension system. This decrease in head acceleration is expected to lead to a reduced likelihood of brain and head injury. Because the RATs absorb energy during tensile extension, they offer increases in energy absorption efficiency. These RAT suspensions can potentially replace or complement existing helmet pad and suspension systems in military, sports, and industrial safety-wear.

Magnetically controllable hydraulic vibration support and a method for adjusting optimal operating mode thereof

FIELD: mechanical engineering.SUBSTANCE: set of inventions relates mechanical engineering. A controlled delay line is introduced in the hydraulic vibration support between the input sensor and the alternating voltage converter. The output sensor is connected to the controllable delay line control unit. The control unit forms a digital signal based on the analysis of the data about the input signal for the previous half-period. The control unit is connected to a controllable delay line which controls the phase of the variable rotating magnetic field relative to the moving flow of the magnetorheological liquid. In the method the signal received from the input sensor passes through a controllable delay line before being fed to the alternating voltage transducer. A damped signal from the output sensor is fed to the control unit. The signal is converted into a sequence of pulses and the amplitudes of two successive pulses are compared. The result of the comparison is analyzed and processed. A digital signal is formed and transmitted to a controlled delay line. This digital signal changes the magnitude and direction of the shift of the controlled delay line and adjusts the voltage phase of the inductor winding.EFFECT: achieved is efficiency and operating reliability of a vibration support.3 cl, 5 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 744 257 C1 (51) МПК F16F 13/08 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК F16F 13/08 (2020.08) (21)(22) Заявка: 2020119987, 09.06.2020 (24) Дата начала отсчета срока действия патента: Дата регистрации: 04.03.2021 (45) Опубликовано: 04.03.2021 Бюл. № 7 2 7 4 4 2 5 7 R U (56) Список документов, цитированных в отчете о поиске: RU 2695472 C1, 23.07.2019.
