Definitions
- the invention relates to a gas valve device for motor vehicles with at least one gas valve having at least one actuator, which is connected to at least one actuator via at least one actuator, the actuator being connected to the actuator, the actuator and / or the gas valve via a ball joint is.
- An air control device in particular for heating and air conditioning systems, is already known from DE 43 02 504 Cl.
- a pivoting air flap and an actuator for the air flap are provided within a ventilation duct.
- An actuator is provided between the actuator and the air flap, each having a ball joint at its ends.
- the object of the invention is to design and arrange an air flap device in such a way that simple manufacture and assembly are ensured.
- the ball-and-socket joint has a ball head made of plastic or metal and a multi-part ball head socket which receives the ball head and is made of plastic or metal. This ensures that the ball head through the multi-part ball head socket for the Assembly can be included at large angles. This inclusion of the ball head ensures high adjustment forces, which can also be aligned in the direction of the ball head shaft or in tension.
- the ball head socket has a first part and a second part, the first part and the second part being connected in an articulated or pivotable manner. Due to the pivotability, the ball head can be used for assembly in one part and the other part is simply folded over it accordingly, so that an essentially closed ball head socket results.
- the ball-head socket has a fastening part which can be connected in a rotationally fixed manner to a receiving part of the actuator, the adjusting part and / or the gas flap.
- the ball head joint formed by the ball head and the ball head socket can thus be integrated into the power flow.
- the fastening part can be integrally or releasably connected to the ball head pan.
- the ball head is positively connected with its shaft to the corresponding adjacent actuator.
- the fastening part and the receiving part can be connected in a rotationally fixed manner, the fastening part having at least one elastic leg which can be latched to the receiving part.
- the lockability ensures simple and quick installation.
- the fastening part is inserted into the receiving part, the plug connection being designed to be non-rotatable, so that the functional rotary movement of the ball head joint takes place between the ball head socket and the ball head.
- the first part and the second part of the ball head socket are connected via a film hinge.
- the film hinge is easy to manufacture and fulfills the required elasticity or strength for assembly.
- the spherical socket has an undercut and encloses the spherical head between 180 ° and 330 °, in particular between 250 ° and 300 °.
- the undercut can be designed according to the desired freedom of movement of the ball head in the ball socket.
- the first part and the second part of the ball head socket each have at least one elastic leg, which in the assembled state has a position closing the ball socket with respect to a parting plane of the ball head socket.
- the fastening part is essentially formed by the two elastic legs which are inserted into the correspondingly shaped receiving part. The elasticity of the legs ensures the locking after insertion and thus a tension lock for the ball joint in the direction of the shaft of the ball head. The security against rotation results from the polygonal form fit between the fastening part formed from the two elastic legs and the receiving part.
- a plurality of gas flaps are connected directly or via an actuating part to a common actuating strip, the actuating strip being operatively connected to the actuator and / or the actuator stands . This means that several gas flaps can be moved simultaneously and synchronously.
- the adjusting bar is made of plastic, a pivot bearing made of plastic being provided between the adjusting bar and the gas flap or the adjusting part.
- the plastic design ensures weight savings and simple manufacture of the gas valve device.
- the rotary bearing designed as a sliding bearing has a securing part which can be locked in the adjusting strip, the gas flap and / or the adjusting part and has at least one stop surface which acts perpendicularly to a bearing axis.
- the lockable securing part can thus simply be inserted and secured in a corresponding bearing bore in the adjusting strip, the gas flap and / or the adjusting part.
- the stop surface and the latching of the securing part offers a form fit that acts parallel to the securing part and acts in the opposite manner between the securing part on the one hand and the adjusting strip, the gas flap and / or the adjusting part on the other.
- the latching is designed as a holding part 9, which has an oval cross section with respect to the axis of rotation and at the same time represents an anti-rotation device.
- Fig. 1 is a perspective view of the actuator
- Fig. 2 is a perspective view of the
- Fig. 3 is a perspective view of the
- Fig. 4 is a perspective view of the actuator
- Fig. 5 is a sectional view of the pivot bearing.
- the actuator 2 has two ball joints 5, 5 '.
- the ball head joints 5, 5 ' consist of a ball head 5.1 and a ball head socket 6, which encloses the ball head 5.1 due to an undercut 6 .6 in the assembled state by about 300 °.
- the ball head 5.1 formed of metal is cast with its shaft in the actuator 2.
- the ball socket 6 is formed in two parts, the first part 6.1 and the second part 6.2 being pivotally connected via a film hinge 6.5. In the assembled state, both parts 6.1, 6.2 have a common parting plane 6.4, which is spanned by the respective closure surface 6.4 when the ball socket 6 is open.
- the ball socket 6 After inserting the ball head 5.1 into the first part 6.1, the ball head socket 6 is closed by pivoting the second part 6.2. A plurality of securing pins 6.3 are provided on the closure surface 6.4, which engage in corresponding securing bores 6.7 or depressions, so that a relative movement of the two ball socket parts 6.1, 6.2 is prevented in the assembled state.
- the ball socket 6 also has a fastening part 7.
- the fastening part 7 essentially consists of two elastic legs 7.1, 7.2, which are each arranged on the first part 6.1 and on the second part 6.2 of the ball socket 6. The elastic legs 7.1, 7.2 are aligned with the closure surface 6.4.
- the two elastic legs 7.1, 7.2 are arranged opposite or mirror-symmetrical with respect to the division plane 6.4.
- the elastic legs 7.1, 7.2 each have a retaining lug 7.3, 7.4 which, according to FIG. 2, latches with the receiving part 4.1.
- an actuator 4 is mechanically connected to the actuator 2 via a receiving part 4.1, and the actuator 2 is mechanically connected to the gas flap 3 via the actuator 3.1.
- the other gas flaps 3 ', 3' 'each have an adjusting part 3.1', 3.1 '', all adjusting parts 3.1 - 3.1 '' being mechanically coupled via an adjusting bar 8.
- the gas flaps 3 - 3 '' each have a gas flap axis 3.2 - 3.2 '' with a seal 3.3 - 3.3 '' and a spacer 3.4 - 3.4 '', which form part of a pivot bearing (not shown) and part of a gas line (not shown).
- the actuator 2 is in this case arranged at its two ends via the fastening parts 7, 7 'within the receiving part 4.1 of the actuator 4 and within the receiving part 4.1' of the adjusting part 3.1.
- the receiving part 4.1 has a square shape and thus represents an anti-twist device for the fastening part 7, the elastic legs 7.1, 7.2 of which have a corresponding parallel orientation.
- the retaining lugs 7.3, 7.4 ( Figure 1) come on the opposite side of the actuator 2 of the respective Receiving part 4.1, 4.1 'to the system or lock there. A loosening of the receiving part 4.1, 4.1 'from the fastening part 7, 7' is prevented.
- the actuator 4 is connected to a first control bar 8 and a second control bar, not shown.
- the actuator 4 has two ball-and-socket joints 5, 5 ′′ for connection to an actuator 2, 2 ′ in each case.
- the respective actuator 2, 2 ' in turn has a second ball-and-socket joint 5', which forms the connection with the adjusting part 3.1 of the respective adjusting strip 8 or the gas flap 3.
- at least one actuator 2 is designed to be variable in length, so that the two adjustment strips 8 can be adjusted relative to one another.
- a pivot bearing 9 made of plastic and designed as a plain bearing is provided between the adjusting strip 8 and the adjusting part 3.1.
- the pivot bearing 9 has a securing part 9.1 which strikes the adjusting bar 8 and can be locked in the adjusting part 3.1 and which holds the pivot bearing 9 together in the axial direction.
