Abstract

The invention discloses an air valve lift device and a vehicle with the same. The air valve lift device comprises an air valve assembly, a middle rocker assembly, a camshaft, a driving rocker and an actuating mechanism. The middle rocker assembly comprises a middle swing arm. The driving rocker is provided with a first profile face and a second profile face. The first profile face is matched withthe middle swing arm. The camshaft drives the driving rocker to act through the middle swing arm. The second profile face is matched with the air valve assembly so as to drive an air valve of the airvalve assembly to move. The actuating mechanism is used for driving the driving rocker to act round an adjusting axis so as to change the lift quantity of the air valve assembly. According to the airvalve lift device, the middle swing arm, the driving rocker and the actuating mechanism are arranged, and thus the lift of the air valve can be changed. In addition, the structure is simple, manufacturing cost is low, the power transmitting path from the camshaft to the air valve lift device is short, and thus driving force transmitting efficiency of the air valve lift device is high.

Description

technical field [0001] The invention belongs to the technical field of vehicle manufacturing, and in particular relates to a valve lift device and a vehicle with the same. Background technique [0002] For an engine with a fixed valve lift, a fixed cam profile and valve lift mechanism can be compromised according to the layout and performance requirements to ensure the performance and fuel consumption goals. However, according to the principle of internal combustion engines, in the low-to-medium speed and load range, a small valve lift can properly reduce the pumping loss, increase the charging efficiency, and improve the power and economy of the engine; The lift can ensure sufficient air intake, reduce throttling loss, and improve the high-speed performance of the engine. Through the variable valve lift technology, it can take into account the power and economy of medium and low speeds and high speeds. [0003] In the related art, the main valve lift devices of the variab...
