Problems solved by technology
Due to the oil leakage and noise problems of the oil pump assembly in the market, the assembly of the split oil pump is troublesome, the assembly cost is high, the weight of the engine is increased, and the power consumption is increased. Considering these problems, for lightweight noise reduction The development of the integral oil pump assembly plays an extremely important role, but the combination of the oil pump and the timing chain cover will easily increase the overall size. In order to ensure the mechanical strength, the strengthening of the structure will also easily lead to an increase in the overall weight

The invention particular relates to a timing chain cover with an oil pump and belongs to the technical field of automobile spare parts. The timing chain cover comprises a cover body; the oil pump is disposed on the inner side of the cover body and comprises a pump shield; the pump shield is combined with the cover body to form a pump cavity; an inner rotor, an outer rotor and a pressure-limiting valve device are disposed in the pump cavity; a shaft hole is formed in the oil pump; the central axis of the inner rotor coincides with that of the shaft hole; a central mounting hole is formed in themiddle of the cover body; and the distance between the central axis of the central mounting hole and the central axis of the shaft hole is H in the vertical direction of the cover body and is h in the horizontal direction of the cover body, the main body wall thickness of the cover body is T, and the relation of T<h<2T<H<18T exists. According to the timing chain cover with the oil pump, the integral structure is further simplified, and assembling is easier; and due to the optimized cover body, the whole weight is reduced, the mechanical strength is enhanced, the problem of oil leakage and noise are solved, an engine runs more stably, the noise is lowered, the power consumption is reduced, and the service life is prolonged.
Description
technical field [0001] The invention belongs to the technical field of auto parts, and relates to an oil pump and a timing chain cover on an automobile engine, in particular to a timing chain cover with an oil pump. Background technique [0002] The timing chain cover can play the role of dust prevention, preventing dirt and sundries from entering the timing to prevent damage to the timing belt. Due to the oil leakage and noise problems of the oil pump assembly in the market, the assembly of the split oil pump is troublesome, the assembly cost is high, the weight of the engine is increased, and the power consumption is increased. Considering these problems, for lightweight noise reduction The development of the integral oil pump assembly plays an extremely important role, but the combination of the oil pump and the timing chain cover will easily increase the overall size. In order to ensure the mechanical strength, the strengthening of the structure will also easily lead to ...
