Definitions
- the invention relates to a throttle valve connector with a setpoint transmitter flanged on one side, which has an actuating shaft connected to an actuating lever and supported by two bearings.
- Such throttle body are present in motor vehicles, for example for speed control or idle control, the throttle valve is motor-adjustable.
- the throttle valve shaft In the case of throttle valve bodies of this type, the throttle valve shaft must not be connected to the actuating shaft in a rotationally fixed manner be so that the setpoint of the setpoint generator is not at the same time by the movements of the throttle valve shaft can be adjusted. If the control shaft and the throttle valve were connected to one another in a rotationally fixed manner, then a throttle valve traveling in the open direction due to a fault would inevitably set the setpoint higher and the throttle valve would open completely.
- the invention has for its object a throttle body of the type mentioned train that he builds as compact as possible, but coupling the actuating shaft to the throttle valve shaft can be avoided.
- the positioning shaft can be dispensed with on the side of the throttle valve shaft because it is held on one side by the throttle valve shaft.
- a turning of the control shaft through the throttle valve shaft is excluded, however, since the actuating shaft can be rotated in the throttle valve shaft is stored. Thanks to the invention, the size of the throttle body can be reduced without that this results in safety-related disadvantages.
- a particularly high level of security against the throttle flap being raised due to an error can be achieved if the positioning of the control shaft in or on the throttle valve shaft two relatively has mutually rotatable bearing surface pairs.
- Such storage is redundant. Should it be one Blocking of two related storage areas come up, so the other two storage areas can turn the other pair of bearing surfaces relative to each other so that the rotatable bearing is obtained remains.
- the throttle valve connector is particularly simple in construction, if according to an advantageous Embodiment of the invention, the actuating shaft with a bearing pin rotatably engages in a bearing bush, which in turn is arranged rotatably in a bearing bore of the throttle valve shaft.
- Alignment errors between the control shaft and the throttle valve shaft can be compensated that the bearing journal is spherical.
- the overall manufacturing cost is particularly low if the bearing bush is made from a bearing metal consists. This allows very good frictional relationships between the bearing journal and the bearing bush achieve on the one hand and on the other hand between the bearing bush and the wall of the bearing bore.
- the bearing bush can also be used Form crowned on the outside.
- Another embodiment of the invention which also has two independently rotatable bearing surface pairs has, is that in the facing end faces of the throttle valve shaft and the actuating shaft in alignment with each other, a bearing bore is provided and that a bearing pin rotatably engages in both bearing bores.
- the bearing pin in a bearing bore with a spherical bearing journal and is supported in the other bearing bore with a cylindrical bearing journal.
- FIG. 1 partially shows a throttle valve connector 1 to which a setpoint device 2 is flanged is.
- a throttle valve shaft 3 is rotatably mounted, which is a throttle valve 4 supports.
- an actuating shaft 5 is arranged in the setpoint generator 2, which is non-rotatable is connected to an actuating lever 6 with which the setpoint generator 2 is adjusted by a desired setpoint to specify. Not shown in the drawing is on the side opposite the setpoint generator 2 of the throttle valve connector 1 arranged servomotor, the throttle valve shaft 3 according to the specifications of the setpoint generator 2 is adjusted.
- the adjusting shaft 5 is on the side facing away from the throttle valve shaft 3 in the usual way by means of a Rolling bearing 7 is mounted in the housing 8 of the setpoint generator 2.
- a bearing pin 9 On the throttle valve shaft 3 facing On the side, the adjusting shaft 5 engages with a bearing pin 9 in a bearing bore 10, which is from the front side leads into the throttle valve shaft 3.
- the tolerances of the components in the connection area between the throttle valve shaft 3 and the actuating shaft 5 are such that the journal 9 with a relative movement between the actuating shaft 5 and the throttle valve shaft 3 rotates in the bearing bush 11. However, if there is a seizure in this area, then the bearing bush 11 can rotate with the bearing pin 9 in the bearing bore 10.
- journal 9 has to compensate for misalignments
- Actuating shaft 5 has a spherical surface.
- the bearing bush 11 in the bearing bore 10 is cylindrical inside and out.
- the bearing pin 9 normally rotates in the bearing bush 11, however, the bearing bush 11 can also move in this region if it is difficult to move twist in the bearing bore 10.
- a bearing bore is also in alignment with the bearing bore 10 in the end face of the actuating shaft 5 12 provided.
- a bearing pin 13 is rotatably seated in the bearing bore 10 with its spherical pin 9 and has on its opposite side a cylindrical pin 14 which is rotatable in the bearing bore 12 sits. In this way, two bearing points are again realized, so that when the one bearing position the other can allow a rotary movement.
- the adjusting shaft 5 engages with a pin 9 into the bearing bore 10 of the throttle valve shaft 3.
- a kinematic reversal is also possible, according to which the throttle valve shaft 3 would engage with a pin in the actuating shaft. It is also conceivable that the actuating shaft does not engage in the throttle valve shaft, but over the throttle valve shaft.
