Title:
CONTINUOUS VARIABLE VALVE LIFT SYSTEM AND CAR
Document Type and Number:
WIPO Patent Application WO/2017/107626
Kind Code:
A1
Abstract:
A continuous variable valve lift system comprises a drive oscillation arm (10), a camshaft (50), and a valve mechanism (60). The valve mechanism (60) comprises a roller rocker arm (61) and a valve (62) connected to the roller rocker arm (61). The drive oscillation arm (10) has a drive surface (13). The drive surface (13) is in contact with the roller rocker arm (61) to drive the valve (62) to perform a reciprocating movement. The continuous variable valve lift system further comprises an intermediate shaft (40), an adjusting block (20), and an adjusting oscillation arm (30). The drive oscillation arm (10), the adjusting block (20), and the adjusting oscillation arm (30) are fit to the intermediate shaft (40), and can all separately oscillate about the intermediate shaft (40). A first connecting portion (12) is disposed on the drive oscillation arm (10). A second connecting portion (22) is disposed on the adjusting block (20). A third connecting portion (32) is disposed on the adjusting oscillation arm (30). The second connecting portion (22) is located between the first connecting portion (12) and the third connecting portion (32). Two sides of the second connecting portion (22) are respectively in contact with the first connecting portion (12) and the third connecting portion (32). A contact surface between the second connecting portion (22) and the third connecting portion (32) is a helical surface. Further, the adjusting block (20) can slide along an axial direction of the intermediate shaft (40). The camshaft (50) and the adjusting oscillation arm (30) are in contact. Further disclosed is a car having a continuous variable valve lift system. The continuous variable valve lift system and the car having the system can adjust a duration of valve lifting and a duration of valve opening.
