Problems solved by technology

Further, since unwanted intermediate setting modes must be traversed in order to reach the desired setting mode, on average a long setting distance must be traversed, thus increasing wear

Embodiment Construction

[0042] In the drawings, the same reference numerals are used for the same or corresponding components in the embodiments.

[0043] In the drawings, for the sake of simplification, substantially known components such as the casing of the ventilation control device or the motor are not shown in FIGS. 1-3 .

[0044] Figure 1A-D designates a cam disc 1 with guide cams 11 formed by corresponding guide tracks or grooves in the side of the cam disc 1 . Via a single-arm control lever 10 , which is connected to the bearing shaft of the air volume distribution flap 9 for co-rotation therewith, the guide cam 11 controls the pivoting or tilting position of said air volume distribution flap 9 . For the sake of simplicity, only one air distribution flap 9 , one guide cam 11 and one control lever 10 are shown, although in a known manner a large number of such air distribution flaps are provided for the purpose of setting the required air flow. The air volume distribution flaps are driven b...

Abstract

The invention relates to a ventilation control device for a heating and / or air-conditioning system of a vehicle, comprising: at least one air distribution flap (9) for controlling the airflow; a cam disc (1) with at least one guide cam (11 ), which is operatively connected to the air volume distribution flap (9) to set the position of the flap according to the angular position of the cam disc (1), which is indicated by an electric actuator, and has a mechanical end stop (21), It interacts with a mechanical stop to define a home position for the electric actuator; wherein the mechanical stop (23) is movably mounted and can be accessed by a further actuator (13), which can selectively The stopper (23) moves to the operating position or the neutral position. In the operating position, the end stop device (21) of the cam disc (1) hits the mechanical stopper (23). In the neutral position, the cam disc (1) The end stop (21) cannot hit the mechanical contact stop (23).

Description

technical field [0001] The present invention relates to a ventilation control device for a heating and / or air-conditioning system of a motor vehicle. For simplicity, the heating and / or air-conditioning system will be referred to simply as the air-conditioning system hereinafter. Background technique [0002] In order to reduce the overall cost of the air conditioning system, the multiple air flaps used for ventilation control in the installation are usually controlled by the same "modedisk", such as a mechanical cam disc, and an actuator connected to the cam disc. The drive means is typically an electric motor or a manually settable knob. [0003] For example, German Patent No. DE19528714 proposes to use a single cam disc to control two mixing flaps for mixing temperature. [0004] In addition to the mix temperature, another known practice is to use a single cam disc and a single actuator to control the actual distribution flaps in the ventilation control. The air volume d...
