Abstract
The utility model relates to an engine camshaft cover using the VVT technology, comprising a threaded hole, a gasoline inlet and outlet ports, wherein, the threaded hole is used for connecting with the engine cylinder head; the outlet port is communicated with the bearing. The utility model is characterized in that: a setting hole of an electromagnetic valve which is adapted for the electromagnetic valve in the VVT components and an oil line which is communicated with the electromagnetic valve are arranged at the two ends of the bearing cover; the oil line of the electromagnetic valve is communicated with the outlet port at the gasoline inlet. As the VVT oil line and the electromagnetic valve are both arranged on the bearing cover, under the situation of taking the camshaft-positioning as the main goal, the VVT oil line, the electromagnetic valve and the bearing cover are integrated; using the VVT technology in the limited space, the bearing cover bears the installation of the electromagnetic valve, which has the advantages of reasonable arrangement and full use of the space, besides, the whole oil line has the advantages of compact arrangement and reasonable structure. The utility model is suitable for various engine camshaft covers using the VVT technology.
Description
Technical field
The utility model relates to a kind of vehicular engine camshaft-bearing cap, more specifically to a kind of employing VVT (Variable Valve Time) technology engine camshaft bearing cap.
Background technique
Engine camshaft bearing cap in the past has only an effect, and that is exactly the positioning cam axle, and what prevent that it is in operation beats.Its structure is that it is Spielpassung that camshaft-bearing cap places camshaft top and camshaft, prevents circular runout and the axial motion of camshaft in running.This structural design is not generally used when motor does not adopt VVT (Variable Valve Time) technology.If but during engine configurations VVT structure, the layout of VVT oil circuit and the rigging position of control valve last have to have under the valve chamber cover in the limited space of cylinder cap want connection and reasonable arrangement, the structural design of this single function of existing bearing lid certainly will be able to not meet the demands, and the complete machine lubrication system is arranged cause very big influence.
Summary of the invention
The technical problems to be solved in the utility model is, in order to remedy the deficiency of the existing VVT of employing technology engine camshaft bearing cap, a kind of suitable spatial arrangement, VVT oil circuit are unified with lubricating oil path, engine camshaft bearing cap rational in infrastructure and provide.
The utility model is to solve the problems of the technologies described above to adopt following technological scheme: a kind of engine camshaft bearing cap of the VVT of use technology, include tapped hole, oil inlet hole that connects usefulness with engine cylinder cover and the oil outlet that leads to bearing on the bearing cap, it is characterized in that: the bearing cap two ends also be provided with the VVT parts in the adaptive solenoid valve mounting hole of solenoid valve and lead to the solenoid valve oil circuit, solenoid valve oil circuit and oil outlet connect at the oil inlet hole place.、
For making whole VVT parts and the equilibrium of bearing cap lower bearing oil pressure, lead to the solenoid valve oil circuit on the described bearing cap, oil outlet can also be the center symmetric arrangement with the oil inlet hole.
Control valve determines whether the fuel feeding to VVT according to actual conditions and nominal data.
Good effect of the present utility model is, owing to adopt VVT oil circuit and solenoid valve all to be arranged on the bearing cap, orientating as under the main purpose to camshaft, not only VVT oil circuit, solenoid valve and bearing cap combine, in limited space, adopt the VVT technology, bearing cap has carried the installation of solenoid valve, and reasonable Arrangement has made full use of the space; And whole oil circuit is arranged compact, rational in infrastructure.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the bearing cap rigging position organigram among the utility model embodiment.
Fig. 2 is the bearing cap structural upright schematic representation among the utility model embodiment.
Fig. 3 is A-A figure among Fig. 2.
Fig. 4 is B-B figure among Fig. 3.Oil circuit is shown to distribute.
Among the figure: 1. bearing cap, 2. phase discriminator, 3. solenoid valve, 4. camshaft, 5. lead to solenoid valve oil circuit, 6. oil inlet hole, 7. oil outlet, 8. solenoid valve mounting hole.
Embodiment
In Fig. 1, in the overhead double-cam VVT parts, pair of cams axle 4 connects phase discriminator 2, the tight bearing cap 1 of the lid on the camshaft 4.Be connected with a pair of solenoid valve 3 in the VVT parts at the two ends of bearing cap 1.
As Fig. 2, Fig. 3, shown in Figure 4, a kind of engine camshaft bearing cap that uses the VVT technology, include tapped hole, oil inlet hole 6 that connects usefulness with engine cylinder cover and the oil outlet 7 that leads to bearing on the bearing cap 1, it is characterized in that: bearing cap 1 two ends also be provided with the VVT parts in the adaptive solenoid valve mounting hole 8 of solenoid valve 3 and lead to solenoid valve oil circuit 5, solenoid valve oil circuit 5 connects at oil inlet hole 6 places with oil outlet 7.Lead to solenoid valve oil circuit 5 on the described bearing cap 1, oil outlet 7 can also be the center symmetric arrangement with oil inlet hole 6.
Bearing cap oil circuit working procedure is: oil enters cylinder cap from oil sump, earlier enter bearing cap 1 by oil inlet hole 6 by the cylinder cap main oil gallery, branch left and right sides two-part oil circuit enters solenoid valve mounting hole 8, a tunnel (being the low pressure oil circuit) and enters bearing cap by oil outlet 7 again, and grease cylinders covers other parts; Another road enters VVT (being high-pressure oil passage) by solenoid valve 3 again and lubricates upward other parts of VVT.Solenoid valve determines whether the fuel feeding to VVT according to actual conditions and nominal data.As can be seen from Figure 1, in cylinder cap is arranged limited space,, it is compact that whole cylinder cap is arranged, saves the space.
Claims (2)
1. engine camshaft bearing cap, include tapped hole, oil inlet hole (6) that connects usefulness with engine cylinder cover and the oil outlet (7) that leads to bearing on the bearing cap (1), it is characterized in that: bearing cap (1) two ends also be provided with the VVT parts in the adaptive solenoid valve mounting hole (8) of solenoid valve (3) and lead to solenoid valve oil circuit (5), solenoid valve oil circuit (5) is located to connect at oil inlet hole (6) with oil outlet (7).
2. engine camshaft bearing cap according to claim 1 is characterized in that: it is the center symmetric arrangement with oil inlet hole (6) that described bearing cap (1) is gone up towards solenoid valve oil circuit (5), oil outlet (7).
