Abstract
The utility model relates to a cap type hydraulic tappet oil supplying channel of motorcycle engine head, relating to the motorcycle engine head and cap. The prior motorcycle engine head and cap has the shortcomings that the hydraulic tappet oil supplying channel is arranged to supply oil by the convex wheel shaft, so that the prior motorcycle engine head and cap can not operate normally as hydraulic tappet can not be supply with oil internally and directly. The utility model provides a channel which supplies the hydraulic tappet with oil directly, with the advantages of simple structure and easy operation. The technical proposal of utility model is that two oil channels(5) are communicated with the two ends of the main oil channel(6) of the engine head and cap(8); a guide hole oil channel(4) is communicated between the branch oil channel(5) and the guide hole(9).
Description
One, technical field
The utility model relates to motorcycle engine cylinder head, lid oil supply gallery, especially motorcycle engine cylinder head, cover cup type hydraulic tappet oil supply gallery.
Two, background technique
Existing motorcycle engine cylinder head, lid are provided with the fuel feeding main oil gallery, are to be provided with for the camshaft fuel feeding.Deficiencys such as and cylinder head, lid distribution device adopt a cup type gasket type tappet mechanical structure, exist and can not adjust the valve clearance automatically, and the assembling maintenance is difficulty extremely, and engine noise is big; And adopt cup type hydraulic pressure to adjust tappet automatically, because of the oil inside offering passage directly is not provided, so can not normal operation.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, and is easy to make, and can directly adjust motorcycle engine cylinder head, the cover cup type hydraulic tappet oil supply gallery of tappet fuel feeding automatically to cup type hydraulic pressure.
The technological scheme that the purpose of this utility model adopted is, is provided with two oil ducts that the main oil gallery two ends of its cylinder head of main oil pipe, lid are communicated with in cylinder head, the lid, and connecting between an oil duct and the pilot hole has the pilot hole oil duct.
The utility model is to utilize cylinder head, cover original main oil gallery, connect an oil duct and a pilot hole oil duct again, make the machine oil of main oil gallery, flow to the cup type hydraulic pressure of device in pilot hole along oil duct and pilot hole oil duct and adjust the tappet fuel feeding automatically, make glass type hydraulic pressure adjust the normal operation of tappet energy automatically, improved working stability, promptly adjusted automatically between gas to crack and reduction engine noise.
The utility model has simple and compact for structurely, processes simple and directly, and to engine structure, performance does not all produce any change and influence.
Four, description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is the utility model sectional structure schematic representation;
Fig. 2 is that Figure 1A-A is to the TV structure schematic representation;
Fig. 3 is the utility model and distribution device embodiment sectional structure schematic representation.
Among the figure: 1-hydraulic tappet 2-oilhole 3-annular oil groove 4-pilot hole oil duct 5-props up oil duct 6-main oil gallery 7-valve 8-cylinder head, lid 9-pilot hole
Five, embodiment
As shown in Figure 1, between an oil duct 5 of cylinder head, lid 8 and the pilot hole 9 pilot hole oil duct 4 is arranged.
Fig. 2, an oil duct 5 is connected at main oil gallery 6 two ends of cylinder head, lid 8, and connecting between an oil duct 5 and the pilot hole 9 has pilot hole oil duct 4.
Fig. 3, valve 7 lower ends contact with the hydraulic tappet 1 that has oilhole 2 and annular oil groove 3, and hydraulic tappet 1 device is in the pilot hole 9 of cylinder head, lid 8, and connecting between an oil duct 5 of cylinder head, lid 8 and the pilot hole 9 has pilot hole oil duct 4.
Claims (1)
1, a kind of motorcycle engine cylinder head, cover cup type hydraulic tappet oil supply gallery, be provided with main oil gallery (6) in cylinder head, the lid (8), two oil ducts (5) that it is characterized in that main oil gallery (6) the two ends connection of cylinder head, lid (8), connecting between an oil duct (5) and the pilot hole (9) has pilot hole oil duct (4).
