MULTIPLE VARIABLE VALVE LIFT APPARATUS |
| 摘要 |
A multiple variable valve lift apparatus may include a camshaft rotating by driving of an engine, a cam portion formed in a cylindrical shape having a hollow that the camshaft is inserted into, rotating together with the camshaft, configured to move along an axial direction of the camshaft, and forming a zero cam and a normal cam, a valve opening/closing device configured to be operated by at least one of the zero cam or the normal cam which are formed at the cam portion, an operating device disposed on an exterior circumference of the camshaft so as to move together with the cam portion, and a solenoid configured to selectively move the operating device along an axial direction of the camshaft, in which a journal, which has a radius being equal to a radius of the zero cam, is formed at the cam portion. |

1. A multiple variable valve lift apparatus comprising:
a camshaft rotating by driving of an engine; a cam portion formed in a cylindrical shape having a hollow that the camshaft is inserted into, rotating together with the camshaft, configured to move along an axial direction of the camshaft, and forming a zero cam and a normal cam; a valve opening/closing device configured to be operated by at least one of the zero cam or the normal cam which are formed at the cam portion; an operating device disposed on an exterior circumference of the camshaft so as to move together with the cam portion; and a solenoid configured to selectively move the operating device along an axial direction of the camshaft, wherein a journal, which has a radius being equal to a radius of the zero cam, is formed at the cam portion such that a cam cap surrounds an exterior circumference thereof. |
