Abstract

The invention discloses a novel camshaft bearing seat which comprises an upper bearing seat framework (1), an upper bearing seat (8) arranged on the upper bearing seat framework (1), a cylinder cover (2), a lower bearing seat (9) arranged on the cylinder cover (2), bearing seat tightening bolts (4) for fixing the upper bearing seat (8) and the lower bearing seat (9), a first bearing upper bearing seat (3), a first bearing lower bearing seat (6) and a first bearing seat tightening bolt (10), wherein the first bearing upper bearing seat (3) is arranged on the upper bearing seat framework (1), and the first bearing lower bearing seat (6) is fixed on the first bearing upper bearing seat (3) through the first bearing seat tightening bolt (10). The novel camshaft bearing seat can abandon the structural design of arranging the bearing seats and the cylinder cover into a whole through the way of arranging the camshaft lower bearing seat alone, thereby effectively limiting the length of the cylinder cover, reducing the weight of the cylinder cover and being conductive to reducing the weight of an engine.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a camshaft bearing seat for an overhead camshaft engine. Background technique [0002] Most of the existing overhead camshaft engine camshaft bearing housings are separated up and down, and are composed of an upper bearing housing and a lower bearing housing. That is to say, the lower bearing seat is generally integrated on the cylinder head, and the upper bearing seat is fastened to the lower bearing seat with bolts. This kind of camshaft bearing seat structure is easy to affect the compact angle valve arrangement, camshaft arrangement, bearing lubricating oil supply, and cylinder head bolt arrangement and installation, and sometimes causes the position of the lower bearing seat to overlap with the cylinder head bolts. In order to prevent the occurrence of overlapping problems between the bearing seat and the cylinder head bolts, it is often necessary to increase the length of the cyl...
