    摘要： A variable valve lift apparatus includes a high cam and a low cam fixed side by side to a camshaft, an outer body pressed by the rotation of the high cam, and has a crossbar formed at the bottom of the front end, an inner body, of which the front end protrudes further than the outer body, the lower front end is provided with a valve member, the upper rear end is hinged to a lost motion hinge shaft coaxially with the rear end of the outer body, and the lower rear end is pivotally connected to a hinge member, and a latching portion inserted into the inner body and selectively connected to the crossbar of the outer body to move the inner body dependent on movement of the front end of the outer body, wherein the lost motion hinge shaft is disposed in the same direction as a hinge point between the inner body and the hinge member with respect to the camshaft. Dynamic characteristics can be obtained by reducing the moment of inertia of the variable valve lift apparatus, and the dynamic characteristics can be further improved by inserting the latching portion into the inner body so as to be closer to the camshaft.

    摘要： A continuously variable valve lift device for a vehicle is provided, which includes a drive shaft rotating in association with a crank shaft and having a drive cam formed on an outer periphery thereof, a locker arm shaft provided apart from the drive shaft and having one end that supports a rocker arm rotating and rocking in association with the drive cam, output cams rotatably installed on the drive shaft to interlock with the other end of the rocker arm, and a variable drive part straightly moving the rocker arm shaft in a vertical direction of the rocker arm shaft to vary a valve lift. When a valve is shifted from the high-lift state to the low-lift state, a pumping loss is reduced to improve the fuel consumption ratio. Also, since an advance function is provided, an exhaust-side CVVT can be deleted to greatly reduce the manufacturing cost.
