Abstract
An up and down moving mechanism for an air spoiler associated with a movable grill for reducing air resistance is disclosed. The moving mechanism includes a speed sensor detecting the driving speed and transmitting a signal to a control circuit. A thermostat connects to a linkage for controlling the opening and closing of the movable grill in response to the water temperature in a radiator. A motor rotates in response to instructions transmitted from the control circuit and opens a gap between the air spoiler and a bumper. A first circuit detects the position of a thermostat rod and transmits a signal to the control circuit to lift the air spoiler. A second circuit detects a position of a motor rod and transmits a signal to the control circuit to stop a rotation of the motor.
Claims6
In a motor vehicle including a front bumper, a movable air spoiler positioned below said bumper, a movable grill and an engine including a radiator positioned behind said grill, an apparatus for moving said air spoiler between a first position in which a gap is formed between said air spoiler and said bumper and a second position in which said gap is closed, said apparatus comprising:
- first detecting means for detecting the road speed of said vehicle;
- a thermostat including movable output means connected to said grill for opening and closing said grill, said thermostat being actuated in response to the temperature of the water in said radiator;
- means for moving said air spoiler between said first and second postions;
- second detecting means for detecting the position of said thermostat output means;
- third detecting means for detecting the position of said means for moving said air spoiler;
- and
- control circuit means receiving signals from said first, second and third detecting means and supplying signals to said means for moving said air spoiler.
