Abstract
The invention relates to the spare part field of vehicular fully variable valve lift gasoline engines, in particular to a camshaft bearing seat. The camshaft bearing seat comprises a bearing seat body arranged at the upper part of a cylinder cover of a vehicular engine and provided with a mounting hole for mounting a camshaft; an eccentric shaft hole for mounting an eccentric shaft is arranged at one side of the mounting hole, the axes of the mounting hole and the eccentric shaft hole are parallel, and the bearing seat body is provided with a connecting hole for fixing the bearing seat body on the cylinder cover. Because of the camshaft bearing seat arranged at the upper part of the cylinder cover, the fully variable valve lift mechanism has enough motion and mounting spaces, and the bearing seat has the advantages of simple structure, simplicity and convenience of processing and high efficiency.
Description
Technical field
The present invention relates to the full lift range variable petrol engine of automobile part field, particularly a kind of camshaft bearing bush seat.
Background technique
At present, the as a whole foundry goods of the bearing support of engine cam and cylinder body is made processing difficulties, and processing cost is higher, and adopts the installing space behind the full lift range variable petrol engine to be restricted, and difficulty is installed.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, be convenient to the camshaft bearing bush seat of processing and installing.
For achieving the above object, the present invention has adopted following technological scheme: a kind of camshaft bearing bush seat, this camshaft bearing bush seat comprises the bearing support body that is positioned at automobile engine cylinder head top, the bearing support body is provided with the mounting hole that camshaft is installed, the side of mounting hole is provided with the eccentric pivot hole of setting-up eccentricity axle, and the axis of mounting hole and eccentric pivot hole parallels.The bearing support body is provided with the bearing support body is fixed on attachment hole on the cylinder cap.
Because adopt above technological scheme, camshaft bearing bush seat is positioned at cylinder cap top, makes full variable air valve lift range mechanism that enough motions and installing space be arranged, and bearing support is simple in structure, process easy, the efficient height.
