Abstract:
A housing comprising at least one electrical connection through a housing wall that is particularly inexpensive to produce and allows the electronic components located on the internal face and the external face of the housing to be attached in a particularly variable manner. The electrical connection is directly surrounded by housing material while being additionally sealed by means of sealing material. The inventive housing seal is provided with a profiled seal encompassing at least two sealing lips. The sealing material is additionally used for sealing the cover and/or the bottom relative to the housing wall. The arrangement is also particularly well protected against oil and other aggressive media as a combination of housing material and sealing material is used for surrounding the electrical connection.
Abstract:
An electronic circuit arrangement includes a heat sink and a first circuit carrier which is thermally coupled to the heat sink, lies flat on the latter and is intended to wire electronic components of the circuit arrangement. Provided for at least one electronic component is a special arrangement which is associated with a considerably increased heat dissipation capability for the relevant component and, in addition, also affords further advantages in connection with changes in the population and/or line routing which might occur in practice. The important factor for this is that the component is arranged under a second circuit carrier which is held in a recess in the first circuit carrier. The recess passes through to the top side of the heat sink.
Abstract:
A housing (1) with at least one electrical connection (7) through a housing wall (4) can be manufactured especially economically and can facilitate an especially economical lacing of electronic components (2, 13) present on the interior and on the exterior of the housing (1). The electrical connection (7) is enclosed by a housing material and additionally sealed by a sealing material (6). The sealing material (6) also advantageously serves to seal a top (3) and a bottom (5) to the housing wall (4). Through the combination of the casing of the electrical connection (7) of the housing (1) and the sealing material (6), this arrangement is, moreover, especially impervious to oil or other aggressive media.

Abstract:
Connection element for forming a permanent electric connection between a first and a second electric lead (1, 2), each being attached in fixed position to a respective first and second housing (3, 4), such that the housings have guiding means (5) which, when the housings (3, 4) are brought together, co-operate in such manner that the leads are correctly positioned for forming the electric connection and the connection forming device can act upon the electric leads (1, 2) to be connected through openings (7) in the housings.
Abstract:
Method for control of a proportional magnet comprising a magnet core, a magnet armature, a magnet coil for operating a control element in a shift valve or a proportional pressure-control valve, particularly a pressure-control valve for clutch operation in an automatic motor vehicle transmission, and comprising an electronic control device, whereby the magnet core may be moved back and forth between a control region and a hold region with a magnetic hold position of the magnet armature and a defined transition from the control region to the hold position may be executed and whereby mechanisms are provided for recognition of the movements of the magnet armature.
Abstract:
A proportional pressure control valve is described capable of serving as a pilot, servo or direct control valve and having a pressure reducing function and a pressure maintaining function. The valve is comprised essentially of a valve housing (2) with inlet and outlet ports (4, 5, 6), a control element (7), an armature rod (8) and a proportional magnet (3). The proportional magnet (3) is an assembly of a magnet core (10), a magnet armature (11) and a magnet coil (12), whereby the proportional magnet (3) when in its range of operation possesses a nearly constant magnetic strength. In accord with the invention, when in a holding position of the magnetic armature (11) the smallest possible gap (13) exists between the magnet armature (11) and the magnet core (10). This gap is so dimensioned that the magnetic force between the two said components (10, 11) in the holding position is greater than the magnetic force in the operational area of the proportional magnet (3) and that the magnetic armature (11) can be made fixed in position by this said magnetic force.
Abstract:
A method and a device for controlling a fluid-actuated control system of an automatic or automated transmission of a motor vehicle, which has at least one pressure medium source, at least two control elements that are actuated by pressurized fluid and a control device for controlling the fluid-actuated control system. A further control module is used to reduce; the number and power consumption of valves that are actuated simultaneously to control the control elements; and the mechanical loading of the control elements (1, 2). The control module reads signals concerning at least one current control action and, in accordance with predetermined patterns, calculation rules and/or models, generates signals that cause non-switched control elements to be manipulated by pressurized working fluid.
Abstract:
A method for determining the position of a shifting element (11), for example of a sliding sleeve in an automatic transmission of a motor vehicle, with the element actuated by way an actuating element, for example comprising a shifting rod (8) and a shifting fork (10), via an operating element (1). From the actuating pressure and/or the shifting force of the operating element, deformation of the actuating element, for example the shifting rod (8) and/or the shifting fork (10), is determined which result in the position of the shifting element being determined with greater precision.
