Abstract

The invention discloses a continuous variable-lift device. The device comprises a valve mechanism, a transmission mechanism and an adjusting mechanism; the valve mechanism is used for distributing airfor an engine cylinder; the transmission mechanism comprises a rocker arm and a cam; the rocker arm is arranged between the cam and the valve mechanism; a first end of the rocker arm is connected tothe adjusting mechanism; a second end of the rocker arm is matched with the valve mechanism in a contact mode; a rolling wheel is arranged on the rocker arm; the cam is matched with the rolling wheelin a rolling mode; the adjusting mechanism comprises a rocker arm base, a rocker arm adjusting base and an elastic part which is arranged between the rocker arm base and the rocker arm adjusting base;the rocker arm base is used for supporting the rocker arm; and an eccentric wheel is arranged below the rocker arm adjusting base and provides different eccentricity in the rotating process so as tocontinuously and variably adjust the lift of the valve mechanism. The invention further discloses an engine containing the continuous variable-lift device and an automobile. Compared with the prior art, the continuous variable-lift device, the engine and the automobile have the advantages that the continuous variable lift is realized, meanwhile, the cam and the rolling wheel can be kept attached to each other all the time, the structure is simple, the number of parts is small, and the reliability is high.

Description

technical field [0001] The invention relates to the technical field of automobile engines, in particular to a continuously variable lift device, an engine with the continuously variable lift device and an automobile with the engine. Background technique [0002] A vehicle's engine includes a combustion chamber where fuel is burned to generate power. The combustion chamber is provided with intake valves and exhaust valves. The intake valve is used to supply the gas mixture containing fuel, and the exhaust valve is used to discharge the exhaust gas of fuel. The intake and exhaust valves open and close the combustion chambers through a valve lift device connected to the crankshaft. The adjustment of the engine load is realized by controlling the opening of the throttle valve, and the opening of the valve is controlled by the cam line. The cam line of the camshaft of the traditional gasoline engine is fixed, which causes the valve lift of the engine to be constant. . Because...
