Embodiment Construction

[0033] Exemplary embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present invention, but are not intended to exhaust all possible ways of the present invention, nor are they intended to limit the scope of the present invention.

[0034] refer to Figure 3 to Figure 7 A camshaft phaser according to the present invention is introduced.

[0035] Such as Figure 4 As shown, the camshaft phaser according to the present invention includes a stator 1 and a rotor 2 , the rotor 2 is arranged radially inside the stator 1 and can rotate relative to the stator 1 .

[0036] The stator 1 includes a cylindrical stator main body and a plurality (four in this embodiment) of stator protrusions 11 protruding radially inward from the stator main body. The rotor 2 includes a cylindrical rotor body and a plurality (four...

Abstract

The invention provides a camshaft phaser and a vehicle. Rotor blades (21) and stator protrusions (11) of the camshaft phaser are alternately arranged in the circumferential direction to form a plurality of sets of cavities, wherein each set of cavities comprises a first cavity (A) and a second cavity (B); a rotor body is provided with first cavity oil ways (22a) corresponding to the first cavities(A) and second cavity oil ways (22B) corresponding to the second cavities (B); the peripheral wall of the rotor body is provided with at least one oil groove (23) sunken towards the radial inner side; the oil grooves (23) communicate with the first cavity oil ways (22a) or the second cavity oil ways (22B); the side walls, closest to the rotor blades (21), of the oil grooves (23) extend in the axial direction; and when the rotor blades (21) make contact with the stator protrusions (11), openings, facing the radial outer side, of the oil grooves (23) are completely shielded by the stator protrusions (11). The camshaft phaser is simple in structure, low in cost and good in deceleration buffering effect.

Description

technical field [0001] The present invention relates to a camshaft phaser and a vehicle including the camshaft phaser. Background technique [0002] The engine valve timing system is a system used to control the opening and closing time of the valves of the automobile engine. The engine valve timing system optimizes the working performance of the engine by controlling the opening and closing of the valves. The camshaft phaser is one of the important parts of the engine valve timing system. [0003] Such as figure 1 and figure 2 As shown, in order to avoid or alleviate the rotation of the rotor 2 of the camshaft phaser to the extreme position during the circumferential rotation (including the counterclockwise rotation of the rotor 2 relative to the stator 1 to the first limit where the rotor blade 21 contacts the stator protrusion 11 position and the impact noise caused by the mechanical contact between the stator protrusion 11 and the rotor blade 21 when the rotor 2 rota...
