Embodiment Construction

[0034] figure 1 An electromechanical power steering according to the invention is shown with a steering gear 1 which, in a known manner, has a longitudinally displaceably mounted toothed rack, which is not visible in the illustration. The toothed rack is articulatedly connected to the two tie rods 2 . The hinge is correspondingly encapsulated with bellows 3 . Bellows 3 protects the interior of steering gear 1 from environmental influences in the region of the movable components.

[0035] The toothed rack is actuated via the steering column 4 and the toothed toothing, so that when the steering column 4 is turned, the toothed rack and thus the tie rod 2 is displaced in its longitudinal direction. The torque occurring here in steering column 4 is detected by means of a torque sensor. The electric servomotor 6 supports the driver by driving the toothed rack in this construction. exist figure 1 The design shown in corresponds to a hollow shaft motor which is driven through a t...

Abstract

The invention relates to a drain valve for an electromechanical power steering of a motor vehicle, comprising a base (16) and a diaphragm (17), the diaphragm being configured as a movable valve member, and the diaphragm relative to the base (16 ) is movable between the closed state and the open state, wherein the diaphragm (18) rests against the base (16) along the annular projection (30) in the closed state, wherein the base has a channel (23 ), the channel extends from the open opening (24) to the bottom (26), and the diaphragm (18) is centrally fixed on the bottom (26), wherein the bottom (26) has at least one notch (28), at least one notch is the connection from the passage (23) to the membrane (18), and wherein the bottom (26) has at least one groove (29) open towards the membrane (18) and from at least one The notch (28) extends to the annular protrusion (30).

Description

technical field [0001] The invention relates to a drain valve with an umbrella-shaped diaphragm and to an electromechanical power steering with such a valve. Background technique [0002] Power steering systems for motor vehicles are generally known and commonly used. These power steering supports the steering movement of the driver and thus allow easy actuation of the steering, especially in heavy vehicles. In the past, the main components of the power steering were hydraulically driven, wherein the hydraulic equipment was arranged in the housing of the steering. These diverters are well protected from water intrusion. Self-invading water is only serious in the long run in such steering gears, since it can lead to corrosion. [0003] In contrast to this, electromechanical power steering systems have recently been used more and more, especially in smaller vehicles. The electromechanical power steering has the advantage that it can be controlled very flexibly by the elect...
