Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. 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. 2. The timing chain cover according to claim 1 , wherein the damping resin layer has a thickness of 10 μm or more. 3. 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. 4. The mounting structure for a timing chain cover according to claim 3 , wherein the damping resin layer is formed on the abutment surface of the chain cover main body, the damping resin layer being included in the timing chain cover. 5. The mounting structure for a timing chain cover according to claim 3 , wherein the damping resin layer has a thickness of 10 μm or more.
