摘要： A tyre pressure sensor for motor vehicles contains a reference pressure chamber (19) in the form of a manometric switch comprising a contact membrane (22) and a contact pin (23). The threshold value of the manometric switch is varied in function of the rotational speed. For this purpose, the reference pressure chamber (19) is sealed on the rim side by an annular membrane (28) whose inner edge is connected to the housing of the manometric switch and whose outer edge (29) is connected via an inertia ring (26) to the contact membrane (22).

摘要： A tyre pressure sensor for motor vehicles is inserted in the rim (12) of one of the wheels of the vehicle. The sensor has a reference pressure chamber (18) which is closed on the side nearest the tyre by an electrically conductive membrane (20) and which co-operates with an insulated contact pin (22) inserted centrally through the floor of the reference pressure chamber (18) and with an oscillating circuit connected to the contact pin (22). In order to detect a deformation of the membrane due to damage caused when the tyres are mounted as well as two or more different threshold values of the tyre pressure, in addition to the central contact pin (22) at least one additional insulated contact body (34) is inserted through the floor (19a) of the reference pressure chamber. On further deflection of the membrane, the additional contact body (34) touches the contact pin (22) thereby closing a second circuit.

摘要： A pneumatic switch, in particular for controlling the inflation pressure of tyres, has an electrically conductive diaphragm (5) that covers a reference pressure chamber (4) and is sealed around its circumference to a housing (2). When the inflation pressure to be controlled exceeds a given threshold value, the diaphragm (5) bears against a contact pin (7) which extends through the reference pressure chamber (4). A pressurized medium inlet stub fills the reference pressure chamber (4) with a gas under a predetermined pressure. In order to obtain a particularly simple, cost-effective design with a good and defined sealing effect, the contact pin (7) has a longitudinal channel (11) and acts as an inlet stub for the pressurized medium.

摘要： In a tyre pressure sensor for motor vehicles with a pressure switch having a reference pressure chamber (28) connected to the inner side of the tyre via an electrically conductive contact diaphragm (24) arranged parallel to the tyre tread which co-operates with a fixed-casing switching contact (23) depending on the relative tyre pressure and which, in order to raise the switching threshold of the pressure switch depending on the speed, is lifted by a mass radially movable under the effect of centrifugal froce depending on the speed of rotation, there are arrangements, in order to achieve a certain speed-dependent shift, specially tailored to the actual application, in the response threshold independently of the pressure-difference-dependent switching behaviour, for the outer surface of the somewhat cylindrical reference pressure chamber (28) to be formed by a bellows (26) linked along its outer edge (25) to the diaphragm (24).

摘要： A tyre pressure sensor (13) for monitoring the pressure of vehicle tyres is mounted radially to the wheel axis on the periphery of a rim and has a reference pressure chamber (20) with a contact pin (22) which cooperates with an electrically conductive membrane (21) which seals the reference pressure chamber (20) against the tyre. In ordr to raise the switching threshold of the tyre pressure sensor (13) as a function of the speed, an additional load (30) is free-mounted on the center of the membrane and is dimensioned so that, for a predetermined radius r of the membrane (21), a predetermined radius of rotation r of the membrane (21) and a predetermined speed of rotation v of the membrane (21), the switching threshold is increased by a desired pressure difference ( DELTA p) over the switching threshold po when the wheel is stationary. The necessary additional load (m) is derived from the relation m=f ( DELTA p, v, r, R).
