Engine timing encloser installation structure easy to assemble and disassemble

Abstract

The invention discloses an engine timing encloser installation structure which comprises a timing encloser and a cylinder body. The timing encloser is arranged on the cylinder body by a buckling structure. The buckling structure comprises a chuck on the timing encloser, a ball head bolt on the cylinder body and a connecting piece for intermediate transition connection; both ends of the connecting piece are respectively provided with a clamping groove matched with the chuck and a ball head groove matched with the ball head bolt; the timing encloser is clamped with the clamping groove of he connecting piece by the chuck and the cylinder body is connected with the ball head groove on the connecting piece by the ball head bolt so as to implement connection of the timing encloser and the cylinder body. Due to adoption of the buckling connection method, the engine timing encloser installation structure is very convenient to carry out assembling and disassembling operations and has high labor efficiency. Furthermore, to avoid rigid connection of the timing encloser and the cylinder body, a rubber component is used as the connecting piece, so that the resonance risk is reduced and NVH (Noise Vibration and Harshness) quality of an engine can be promoted.

Description

technical field [0001] The invention belongs to the automobile engine technology, and in particular relates to the installation structure of the engine timing cover and the cylinder block. Background technique [0002] The engine timing cover is a component that assembles and protects the engine timing gear train. Now the timing cover is generally fixed on the cylinder block and cylinder head with 8-10 bolts. figure 1 It is a traditional engine timing cover installation structure, and the timing cover 1 is installed on the cylinder block and the cylinder head by 10 bolts 5 . For the maintenance of the timing gear train, all the mounting bolts need to be disassembled one by one, which is labor-intensive and time-consuming, and special tools are required, the maintainability is poor and the maintenance cost is high. In addition, since the timing cover and the cylinder block are rigidly connected by bolts, resonance is likely to occur between the two, which affects the NVH qua...
