摘要:
In known retaining devices for electric motors, rotationally flexible retaining elements on the order of leaf springs are provided between a receiving housing and the electric motor and serve to decouple noise of the electric motor. The novel retaining device for an electric motor includes retaining elements that extend axially between a receiving housing and the motor housing. These retaining elements enable low-frequency decoupling below the frequencies to be decoupled; on the occurrence of natural resonance when the electric motor is turned on and off or there are shocks from outside, the torsional motion of the retaining elements is limited by stop elements. The retaining device is especially well suited to electric motors of blowers.

A device for engine cooling includes at least one mechanical coolant pump driven by the engine to be cooled and at least one electric coolant pump controlled by an electronic switching device being provided in at least one cooling circuit of an engine to be cooled. The conveying capacity of the electric pump is set as a function of operating variables of the engine to be cooled and of further variables, while the mechanical pump is designed for a basic conveying capacity. In the coolant circuit a heat exchanger which is operated as a radiator, the cooling capacity of which can be altered with the aid of a radiator blind and of a fan, is arranged in a first coolant path. An additional heat exchanger, the waste heat of which is used for heating purposes or for further engine cooling, is arranged in an additional coolant path or in a separate coolant circuit.
摘要:
A thermal radiation sensor is suggested which comprises two receiver surfaces exposed to the radiation, one receiver surface (1) having a high absorption capacity with respect to the thermal radiation, the other (2) having a low absorption capacity, the two receiver surfaces (1) and (2) consist of a NTC resistance material and are combined in a bridge circuit together with two temperature-independent cermet resistors (3) and (4). In order to prevent a dependency of the measurements of such a sensor on the ambient temperature, the NTC resistors (1) and (2) comprise underlying heating layers (6) and (7) which keep the two NTC resistors at a constant temperature. Insulating layers (8) and (9) are provided between the NTC resistors (1) and (2) and the heating layers (6) and (7). The heating layers (6) and (7) consist of a cermet thick film with platinum or of a platinum thick film and have the shape of a meander. The insulating layers (8) and ( 9) preferably consist of a crystallizing glass.

A device (10) for mounting an electric motor (18), in particular a fan motor, includes an essentially pot-shaped receptacle housing (12)—functioning as motor housing (32)—with a receiving opening (14) into which at least part of the electric motor (18) extends. A holding flange (34) is attached to the receptacle housing (12) for mounting the motor housing (32) to a carrier element (36), e.g., a motor vehicle heater system and/or air conditioner. A mechanism for immobilizing the electric motor (18) radially and axially in the motor housing (32) is included. The receptacle housing (12) includes at least one resilient-elastic holding element (50, 52, 90) for axial immobilization.
摘要:
A humidity sensor, and particularly a sensor which can distinguish between low humidity values, for example below 60% humidity, and high humidity values, for example 90% humidity and thereover, and change the capacitance between output electrodes (5, 6) is formed by applying interdigited comb electrodes (1, 2) on a substrate (8) and applying over the substrate a ceramic mass formed of BaRuO.sub.3, V.sub.2 O.sub.5 and Na.sub.2 WO.sub.4, with a weight relationship of (1.+-.0.4):(1.+-.0.4):(0.6.+-.0.2) preferably 1:1:0.6. The sensor is made by first making a powder of the components, mixing it with a glass paste and, if necessary, a thinner, and applying the resulting paste by thick-film technology to a ceramic substrate on which the electrodes have been applied, and then firing the substrate at a temperature of between 550.degree. C. to 850.degree. C. The sensor is particularly sensitive in humidity ranges above 60% relative humidity and is especially suitable to sense fogging of the inside of a windshield of an automotive vehicle.

摘要:
An air blower sucks air from an area of an air heated compartment of a motor vehicle and blows out an air stream into a different area of the compartment. A temperature sensor is located in the air stream at a relatively large distance from the air blower so as to entrain ambient air from the compartment. Due to the mixing of the discharged air stream with the ambient stream, an information about the overall temperature in the compartment is detected by a single temperature sensor.
摘要:
A temperature-sensing module is described, including a measuring element sensitive to temperature, such as an NTC resistor. In order to reduce the thermal influence of the housing of the element and of the electrical connection, and also to improve the mechanical stability and resistance against vibrations, the connection wires of the element are attached to conductive webs formed side-by-side on a carrier plate of an electrically and thermally insulating material. The conductive webs at one end have enlarged areas which are connected to the connection wires of the sensitive element, and the connecting part of each web is relatively narrow in cross section and has a meander-like configuration. The transition between the enlarged part and the meander-like part is further restricted in cross section to reduce the thermal influence to a minimum. The other end of the meander-like conductive parts is again enlarged in area and forms a contact terminal points attachable to the pins of the connector plug, for example.
摘要:
The method of operating a windshield wiper intermittently requires an apparatus including a rain sensor (12), which generates a signal (S) depending on an amount of rain on the windshield, and a signal processing device (13), e.g.a microprocessor with internal A/D and D/A converters, connected to the sensor (12) to receive the signal (S) and, a control unit connected to the signal processing device (13), and, advantageously, a device for measuring a wiping process duration (T) and inputting the duration to the microprocessor and a drive for the windshield wiper connected to the signal processing device (13). According to the method, the windshield wiper is operated by the signal processing device at least partially according to the signals (S) from the sensor so that the time interval (I) between successive current wiping processes, depends, in part, on a duration (T.sub.-1, T.sub.-2, . . . T.sub.-n) of at least one past wiping process (W.sub.-1, W.sub.-2, . . . W.sub.-n); in part, on a number of signals (S) received from the sensor (12) in a certain time interval F set in the signal processing device; in part, on at least one of two intervals (I.sub.-1, I.sub.-2, . . . I.sub.-n) between past wiping processes (W); and also depends, in part, on at least one time interval (D.sub.0,D.sub.-1, . . . D.sub.-n) between successive ones of the signals (S.sub.0,S.sub.-1 ;S.sub.-1,S.sub.-2, . . . S.sub.-n,S.sub.-n-1).

摘要:
An ion conductive sensor is connected to a current source which, in order to prevent polarization effects, controls current flow through the sensor in spaced or polarity-alternating pulses. If the sensor is a humidity sensor, it is preferably constituted by Cr.sub.2 O.sub.3, V.sub.2 O.sub.5 and Na.sub.2 WO.sub.4 in a proportion, by weight, of preferably 2 to 2.5:1:1, sintered on a substrate which has comb electrodes applied thereto. The sensor is especially immune to noise or disturbance pulses from the current supply and is especially suitable for use as an ambient humidity sensor in an automotive vehicle (810).
