Inspection system for continuous variable valve lift device |
摘要 |
An inspection system for a continuous variable valve lift device includes: a drive motor configured to rotate a cam; a sensor unit including at least one sensor configured to output an electrical signal corresponding to rotational displacements at both ends of a swing arm which opens and closes a valve by receiving rotational motion of the cam through the continuous variable valve lift device; and an inspector configured to measure and inspect a valve lift of the continuous variable valve lift device by receiving and calculating the electrical signal of the sensor unit, and is installed in a vehicle engine assembly line to accurately measure and inspect the valve lift after the continuous variable valve lift device is assembled. |

1. An inspection system for a continuous variable valve lift device, comprising:
a drive motor configured to rotate a cam; a sensor unit including at least one sensor configured to output an electrical signal corresponding to rotational displacements at opposing ends of a swing arm that opens and closes a valve which is engaged to one end of the swing arm, by receiving rotational motion of the cam through the continuous variable valve lift device; and an inspector configured to measure and inspect a valve lift of the continuous variable valve lift device by receiving and calculating the electrical signal of the sensor unit, wherein when the continuous variable valve lift device is a six joint link type, and lengths at the opposing ends of the swing arm are different from each other, the inspector calculates the valve lift by multiplying a rotational displacement amount at one of the opposing ends of the swing arm by a constant value, and adding a rotational displacement amount at the other of the opposing ends of the swing arm thereto. |
