Abstract
The invention discloses a sealing structure at a T-shaped joint of an engine which has a good sealing effect, is convenient to assemble and has high reliability. The sealing structure at the T-shaped joint of the engine comprises a first component, a second component and a third component, the key point is that the seal flange surface at the T-shaped joint of the first component, the second component and the third component is provided with a concave part which is filled with a sealant; the first component, the second component and the third component of the engine are made of metal, after the tight contact of the first component, the second component and the third component, the concave part at the seal flange surface, the shared seal flange surface of the first component, the second component and the third component, at the T-shaped joint is filled with the sealant again, the T-shaped joint can be sealed well, the oil of the engine can be prevented from leaking, also the risk that the seal rubber mat can be dropped off into a crank box when the engine is assembled is eliminated. The sealing structure at the T-shaped joint of the engine has strong practicability, the seal requirement of the engine can be satisfied, and the risk that the seal rubber mat can be dropped off into the crank box when the engine is assembled is eliminated.
Description
Technical field
The invention belongs to technical field of automobile engine, specially refer to the sealing configuration of the T shape joint of engine timing cover, cylinder block, oil sump or timing cover, cylinder block, cylinder head composition.
Background technique
The joint of the timing cover of motor, cylinder block, oil sump and timing cover, cylinder block, cylinder head is T shape and connects, conventional engines adopts seal rubber pad that this position is sealed, sealing effect is bad, oil accident often takes place, and has a strong impact on the safety and the working life of motor.In addition, when motor assembled, sealer was lined with the risk that is shed in the crankcase, influenced the efficiency of assembling and the assembly quality of motor.
Summary of the invention
The objective of the invention is to propose the sealing configuration of a kind of good sealing effect, easy to assembly, motor T shape joint that reliability is high.
The sealing configuration of motor T shape of the present invention joint comprises first parts, second parts and the 3rd parts, key is that the sealing flange face of the T shape joint of described first parts, second parts, the 3rd parts is provided with recess, is filled with sealer in the described recess.
First parts of above-mentioned motor, second parts, the 3rd parts are metal and make, after the three closely contacts, common to the three again sealing flange face, it is the recess filling with sealant of the sealing flange face of T shape joint, just can well seal this place, prevent that engine motor oil from revealing, and seal rubber pad is shed to risk in the crankcase when having stopped the motor assembling.
Be convenient processing, described recess preferably is arranged at the seamed edge of first parts or second parts or the 3rd parts.
Specifically, there are following two positions motor T shape joint, and its sealing configuration is as follows:
1, described first parts are timing cover, and described second parts are cylinder block, and described the 3rd parts are cylinder head, and described recess is arranged at the seamed edge at cylinder block top.When assembling, cylinder block is positioned at the bottom of cylinder head, timing cover is at the sidepiece of cylinder block and head, the bottom surface intersection of the top seamed edge of cylinder block, the top seamed edge of timing cover and cylinder head forms T shape and is connected, the seamed edge place is provided with recess at the top of cylinder block, not only easy to process, and also convenient the recess place is carried out gluing in when assembling.
Be convenient processing, described recess is the chamfering at seamed edge place, cylinder block top.
2, described first parts are timing cover, and described second parts are cylinder block, and described the 3rd parts are oil sump, and described recess is arranged at the seamed edge of cylinder block bottom.When assembling, oil sump is positioned at the bottom of cylinder block, timing cover is at the sidepiece of cylinder block and oil sump, the end face intersection of the bottom seamed edge of cylinder block, the bottom seamed edge of timing cover and oil sump forms T shape and is connected, the seamed edge place is provided with recess in the bottom of cylinder block, not only easy to process, and also convenient the recess place is carried out gluing in when assembling.
Be convenient processing, described recess is the chamfering at seamed edge place, cylinder block bottom.
Described sealer is preferably silica gel, as: happy safe 5910 etc., higher mechanical strength is stablized, had to the adsorption performance height of silica gel, good thermal stability, chemical property, is fit to motor is sealed.
The sealing configuration of motor T shape of the present invention joint is easy to process, practical, can satisfy the seal request of motor, and seal rubber pad is shed to risk in the crankcase when having stopped the motor assembling.
