Abstract
Provided is a timing chain cover that allows suppressing vibration transmission. A timing chain cover of the present disclosure houses a timing chain transmitting a rotative force of a crankshaft to a camshaft in one end side of an internal combustion engine. The timing chain cover includes a chain cover main body and a damping resin layer formed on an abutment surface of the chain cover main body. The abutment surface abuts on an internal combustion engine main body. The damping resin layer contains a heat resistant resin and a damping filler. The damping filler converts a vibration energy into a heat energy.
Claims5
A timing chain cover for housing a timing chain transmitting a rotative force of a crankshaft to a camshaft in one end side of an internal combustion engine, the timing chain cover comprising:
- a chain cover main body;
- and
- a damping resin layer formed on an abutment surface of the chain cover main body, the abutment surface abutting on an internal combustion engine main body,
- wherein the damping resin layer contains a heat resistant resin and a damping filler, the damping filler converting a vibration energy into a heat energy.
A mounting structure for a timing chain cover, the timing chain cover being mounted to an internal combustion engine main body with the mounting structure, the timing chain cover housing a timing chain transmitting a rotative force of a crankshaft to a camshaft in one end side of the internal combustion engine, the mounting structure comprising
- a damping resin layer disposed between an abutment surface of a chain cover main body included in the timing chain cover and an abutment surface of the internal combustion engine main body,
- wherein the damping resin layer contains a heat resistant resin and a damping filler, the damping filler converting a vibration energy into a heat energy.
