Embodiment 1

[0030] The first embodiment of the present invention provides an engine valve mechanism, including a camshaft, a transmission mechanism and a valve, wherein the camshaft is provided between the cam and the transmission mechanism or between the transmission member and the transmission member in the transmission mechanism There is a sliding plate, which has a smooth transition profile; the above-mentioned engine valve mechanism also includes a sliding plate control device, which is connected to the sliding plate and is used to control the position of the sliding plate between the cam and the transmission mechanism or the sliding plate in the transmission The position between the transmission part and the transmission part changes the distance of the transmission mechanism through the smooth transition of the sliding plate.

[0031] In this embodiment, a sliding plate is provided between the cam and the transmission mechanism as an example. Take the mechanism in which the cam drives ...

Embodiment 2

[0036] Figure 1-Figure 4 Both are the partial structural diagrams of the engine valve mechanism provided in the second embodiment of the present invention, where figure 1 Shown is the valve closed state of the engine valve train in a kind of valve lift, figure 2 Shown is the valve fully open state of the engine valve train at a valve lift, image 3 Shown is the valve closed state of the engine valve train under another valve lift, Figure 4 Shown is the valve fully open state of the engine valve train under another valve lift. The second embodiment of the present invention provides an engine valve mechanism, which is based on the first embodiment, and further provides a preferred solution, wherein a sliding plate body 5 is formed in the part of the sliding plate 3 extending between the cam and the transmission mechanism 2. The sliding plate body 5 is provided with an accommodation groove on the side away from the camshaft 1; the sliding plate control device also includes a mov...

Abstract

The invention provides a valve timing mechanism for an engine, the engine and an automobile. The engine comprises a cam shaft, a transmission mechanism and a valve, wherein a sliding sheet is added in the transmission mechanism, a molded line for smooth transition is arranged on the sliding sheet, the valve timing mechanism further comprises a sliding sheet control device connected with the sliding sheet and used for control the position of the sliding sheet between a cam and the transmission mechanism, and the distance between the cam and the transmission mechanism is changed through the molded line of the sliding sheet for smooth transition. The valve timing mechanism for the engine, the engine and the automobile achieve change of valve stroke and the molded line by arranging the sliding sheet between the cam shaft and the transmission mechanism, appropriate valve strokes and molded lines are selected according to different working conditions of the engine, and dynamic property and economical efficiency of the engine are improved.

Description

Technical field [0001] The invention relates to automobile engine structure technology, in particular to an engine valve mechanism, an engine and an automobile. Background technique [0002] The engine is a very important part of the car. The engine is equipped with a valve mechanism to control the intake and exhaust of the engine. The valve mechanism generally includes a camshaft, a tappet, a rocker arm and a valve. The camshaft with a certain profile drives the tappet or the rocker arm according to a certain timing relationship, thereby driving the intake and exhaust valves to open according to a certain profile and timing. close. Here, the tappet, rocker arm, etc. that transfer the camshaft control function to the valve is called the transmission mechanism from the camshaft to the valve. [0003] Valve lift and sports profile can directly affect the intake and exhaust effects, thereby affecting the economy, power and emission level of the engine. Engines with fixed valve lift ...
