Description
Technical field
The utility model belongs to the motor car engine field, refers in particular to the improvement to the gas distribution structure of reciprocating engine.
Background technique
The distribution device that present piston of automobile motor adopts is a valve spring camshaft form, and the intake and exhaust performance is reliable.But the cam rotation that has camshaft overcomes the resistance of valve spring, backs down inlet and exhaust valve, consumption of engine power and opens shortcomings such as the opening speed of intake and exhaust channel is low.
Summary of the invention
The utility model provides a kind of air distributing device of reciprocating engine, to solve the cam rotation that there is camshaft in present distribution device, overcome the resistance of valve spring, back down inlet and exhaust valve, want consumption of engine power and open the low problem of opening speed of intake and exhaust channel.The technological scheme that the utility model is taked is: fixedly connected with split type cylinder head bottom 9 in split type cylinder head top 2, there are split head gasket 1 and split head gasket 2 16 in this split type cylinder head top 2 and 9 of split type cylinder head bottoms, distribution axle top bearing shell 4 is positioned at split type cylinder head top, distribution axle lower bearing 10 is positioned at split type cylinder head bottom, distribution axle 15 is rotationally connected with distribution axle top bearing shell and distribution axle lower bearing, the cylinder head inner water sleeve 3 that UNICOM is arranged on split type cylinder head top 2 and split type cylinder head bottom 9, inlet hole 1 and distribution axle top bearing shell air inlet duct 5 on the split type cylinder head top 2, distribution axle lower bearing air inlet duct 6, distribution axle air inlet duct 14, inlet hole 11 on the lower bearing, split type cylinder head bottom inlet hole 12 UNICOMs; Exhaust port 1 ' UNICOM on exhaust port 11 ' on split type cylinder head bottom exhaust port 12 ' and the lower bearing, distribution axle air vent 14 ', distribution axle lower bearing air vent 6 ', distribution axle top bearing shell air vent 5 ', the split type cylinder head top 2; 1～12 pair of air inlet duct 14 and air vent 14 ' are arranged on the distribution axle.
During work, the utility model is connected on the motor, the fixedly connected timing gear of distribution axle one end by the crankshaft gear transferring power, carry out air inlet and exhaust work by inlet air pathway and exhaust passageway.
The utility model advantage is novel structure, makes original air gate type gas distribution system designs simplification by adopting the distribution axle, is easy to electronic control, and intake and exhaust resistance is little, and motor self power consumpiton is low, reliable performance.
