Abstract

The invention discloses a camshaft bearing cover thrust structure. The camshaft bearing cover thrust structure comprises a cylinder cover, a camshaft and a camshaft bearing cover, wherein an intake side cam bearing base and an exhaust side cam bearing base are arranged at the top end of the cylinder cover; the camshaft comprises an intake side camshaft and an exhaust side camshaft; thrust stop ring grooves are formed in the inner ends of the intake side camshaft and the exhaust side camshaft; the inner ends of the intake side camshaft and the exhaust side camshaft are arranged in the intake side cam bearing base and the exhaust side cam bearing base, arranged at the top end of the cylinder cover side by side, through the respective thrust stop ring grooves; the camshaft bearing cover is anintegral camshaft bearing cover, and is provided with an intake side camshaft bearing cover and an exhaust side camshaft bearing cover; and the intake side camshaft bearing cover and the exhaust sidecamshaft bearing cover cooperate with the intake side cam bearing base and the exhaust side cam bearing base of the cylinder cover to fasten the intake side camshaft and the exhaust side camshaft. The camshaft bearing cover thrust structure achieves dual thrust functions, and is reasonable in structure, low in production cost and easy to popularize.

Description

Technical field [0001] The invention relates to the field of engines, in particular to a camshaft bearing cover thrust structure. Background technique [0002] In engine design and development, camshafts are generally divided into center-mounted and overhead-mounted. If an overhead camshaft is used, the camshaft bearing cap and the cylinder head are generally used to fasten the camshaft. Generally, camshaft bearing caps do not have the thrust function. The thrust function is generally designed on the cylinder head, which makes the structure of the cylinder head complicated and inconvenient for casting. [0003] The information disclosed in the background section is only intended to increase the understanding of the general background of the present invention, and should not be regarded as an acknowledgement or any form of suggestion that the information constitutes the prior art already known to those of ordinary skill in the art. Summary of the invention [0004] The purpose of t...
