Abstract
The invention discloses a cylinder head cover convenient for assembling and disassembling an engine. The cylinder head cover is characterized in that a cylinder head cover lower cap is arranged on the top of a cylinder head; a cylinder head cover upper cap is arranged on the top of the cylinder head cover lower cap; a high-pressure oil pipe is arranged on the side corner of the cylinder head cover lower cap; an O-shaped sealing ring is arranged between the cylinder head cover upper cap and the cylinder head cover lower cap; an oil atomizer is arranged on the cylinder head; the high-pressure oil pipe passes through the cylinder head cover lower cap, and is connected with the oil atomizer; the cylinder head cover upper cap is arranged on the cylinder head through a cylinder head cover bolt; the oil atomizer, an air valve bridge assembly, a rocker arm assembly and a ball connector are arranged in the inner cavities of the cylinder head cover upper cap and the cylinder head cover lower cap on the cylinder head. The cylinder head cover is convenient to repair and maintain, and relevant maintenance can be performed by disassembling the cylinder head cover upper cap. Fault hidden dangers are reduced, a part of repair and maintenance items can be performed without detaching the high-pressure oil pipe, air is prevented from entering an oil path, and more fault hidden dangers are avoided.
Description
Technical field
The present invention relates to a kind of cylinder cover of engine, particularly a kind of cylinder head cover of convenient mounting or dismounting motor.
Background technique
Current cylinder head cover is assemblied on cylinder cap, and main purpose has three: 1, dust-proof--and prevent external dust from entering cylinder cap and body; 2, protect--the action of the movement parts such as protection Valve Rocker Organization; 3, seal-prevent the lubricant oil of Valve Rocker Organization from leaking outside.Existing cylinder head cover is all-in-one-piece, the major defect of its prior art be when maintain or break down need adjustment valve clearance time, whole cylinder head cover and high-pressure oil pipe must be pulled down, like this, outside whole Valve Rocker Organization is just exposed to, easily enter dust, foreign material, and in high-pressure oil pipe, also easily enter air.As dealt with improperly, motor can be made to retain potential faults.
Summary of the invention
The object of the present invention is to provide a kind of technical problem that will solve exactly when needs adjustment valve clearance; do not need to pull down high-pressure oil pipe; and suitably protection valve mechanism is not exclusively exposed to outward; structure is simple; easy to manufacture, the cylinder head cover of a kind of convenient mounting or dismounting motor maintain easily, maintained.
Technical solution of the present invention is such, and a kind of cylinder head cover of convenient mounting or dismounting motor, comprises cylinder head cover upper cover, cylinder head cover lower cover, cylinder head, high-pressure oil pipe, valve mechanism cover bolt, air valve bridge assembly, rocker arm assembly, bulb conjunction, oil sprayer, O RunddichtringO, it is characterized in that cylinder head cover lower cover (2) is installed on cylinder head (3) top, cylinder head cover upper cover (1) is installed on cylinder head cover lower cover (2) top, high-pressure oil pipe (4) is arranged on cylinder head cover lower cover (2) side angle, O RunddichtringO (10) is installed between cylinder head cover upper cover (1) and cylinder head cover lower cover (2), oil sprayer (9) is arranged in cylinder head (3), high-pressure oil pipe (4) is connected with oil sprayer (9) through cylinder head cover lower cover (2), cylinder head cover upper cover (1) is arranged in cylinder head (3) by valve mechanism cover bolt (5), oil sprayer (9), air valve bridge assembly (6), rocker arm assembly (7), bulb conjunction (8) is arranged on the cylinder head cover upper cover (1) above cylinder head (3), in the inner chamber of cylinder head cover lower cover (2).
The inclined-plane of cylinder head cover upper cover (1), cylinder head cover lower cover (2) side there is nut, high-pressure oil pipe fixed by pad (4).
Valve mechanism cover bolt (5) is vertically mounted on cylinder head cover upper cover (1) end face.
Cylinder head (3), cylinder head cover upper cover (1), cylinder head cover lower cover (2) its be split each other.
Advantage of the present invention is: 1, maintenance is convenient, only needs to tear cylinder head cover upper cover open, can carry out the maintaining of being correlated with.2, reduce potential faults, part maintains project, and not needing to tear high-pressure oil pipe open can carry out, and avoids air to enter oil circuit, avoids more potential faults.
