Abstract
Description
The present invention relates to an auto tensioner for a vehicle, which prevents foreign matter contained in oil from flowing into the auto tensioner, thereby preventing a mechanical error from occurring.
The vehicle is provided with a hydraulic automatic tensioner for maintaining the tension of the timing belt or the timing chain of the engine. This hydraulic self-tensioner automatically adjusts the tension on the engine belt drive system to reduce noise caused by insufficient tension on the timing belt or timing chain and to maintain tension. In addition, the auto tensioner satisfies the life extension of the belt drive system and the reliability of the engine.
The automatic tensioner is operated by supplying oil in the oil passage of the engine such as a cylinder block and a cylinder head. If foreign substances are contained in the oil, the automatic tensioner is operated due to foreign substances, A sufficient tension is not transmitted to the timing belt or the timing chain due to insufficient supply.
In this way, when the proper level of tension is not maintained in the timing belt or the timing chain, there arises a problem that operation noise is generated.
It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.
It is an object of the present invention to provide an auto tensioner for a vehicle that prevents an operation abnormality of an auto tensioner from being generated due to foreign substances in oil supplied into an auto tensioner.
In order to achieve the above object, an auto tensioner of a vehicle according to the present invention is fixed in a cylinder block adjacent to a timing belt or a chain and is formed with an oil inlet, and is moved by oil introduced through an oil inlet, Or a body with a piston for pushing the chain; And a filtration unit provided at an oil inlet of the body and blocking the foreign substances in the oil flowing into the body through the oil inlet.
The body is provided with a check valve which is provided on the oil inlet side and selectively opened and closed by the inflow oil, and the oil pressure is provided to the piston side when the check valve is opened.
The body is provided with an oil discharge port and a relief valve provided on the oil discharge port side to open the oil discharge port when the inflow oil exceeds a predetermined pressure, thereby allowing oil to flow out into the body through the oil discharge port.
And the filtration portion is formed to cover the entire area of the oil inlet.
The filtration unit is formed of a magnetic material to block metal foreign substances in the oil flowing into the body.
The body is formed with an assembly slot on the oil inlet side, and the filter is formed to be fitted in the assembly slot and has a filter corresponding to the same area as the oil inlet.
The filter is formed by a fitting portion fitted to the assembly slot and a filter, and a bent portion bent at an end of the fitting portion and contacting the body.
According to the auto tensioner of the vehicle having the structure as described above, since the foreign components contained in the oil supplied to the inside of the auto tensioner are blocked, and the internal components of the auto tensioner are caused to malfunction due to the foreign matter, Thereby preventing sufficient tension from being supplied to the timing chain.
