Abstract
The utility model discloses a valve chamber cover cap, which comprises a machine oil inlet, a crankcase ventilation hole and a high voltage cable hole on the external surface of the case body; the utility model is characterized in that a group of wiring grooves in conformity with the quantity of spark-plug wire holes parallel arranged on the external surface. The opening width of wiring groove is less than linear diameter of high voltage wire and the depth is greater than linear radius of the high voltage wire. At least a wire clip is also arranged in high voltage wiring groove, the opening width of the wire clip is less than diameter of the wiring groove. The end of the high voltage wire at the same level with valve chamber cover cap and the other end is bending for adapting the high voltage wire hole. Due to the integration of high voltage wire support and plastic valve chamber cover cap is needed, the integrated valve chamber cover cap can reduce the quantity and costs of spare parts; adopting circular arc groove with clipped high voltage wire structure can make the fixation, maintenance and replacement of the high voltage wire more convenient, reduce assembly work quantity, increase the wiring length of high voltage cable from ignition coil end to spark plug end with rational arrangement, reduce vibration and enhance the normal contact reliability of high voltage wire and spark plug end.
Description
Technical field
The utility model relates to a kind of valve chamber cover, relates in particular to the valve chamber cover that a kind of engine spark plug high voltage wire is arranged.
Background technique
Chinese patent CN02267841.7 discloses a kind of dual valve chamber closure assembly that engine spark plug high voltage damper cover plate is arranged, and it comprises cylinder head, intake valve chamber cover, exhaust valve chamber cover, cover plate.Cylinder head is provided with intake valve chamber, exhaust valve chamber, spark plug is located in the middle of intake valve chamber and the exhaust valve chamber, intake valve chamber cover is fastened on the intake valve chamber of cylinder head respectively with exhaust valve chamber cover and above the exhaust valve chamber, cover plate is fastened on intake valve chamber cover and goes up spark plug and high voltage damper sealing with exhaust valve chamber cover, and high voltage damper is drawn from the threading hole of cover plate rear end.Make spark plug, the high voltage damper can be not contaminated and make the motor outward appearance clean and tidy.But, have complex structure, the high deficiency of cost.
At present, no matter be to single spark plug or dual ignition plug motor, the layout of high voltage wire all adopts mostly on the cover cap of engine valve chamber installs one or more high-voltage conducting wires supports and realizes that the high voltage wire from the spark coil connecting end to the spark plug end arranges.This scheme major defect is:
1. high voltage wire arranges it is to realize by high tension line support, therefore the length that supports and tighten the high pressure line segment is limited by high tension line support, generally be relatively shorter, so when motor comes off from support owing to high voltage wire may appear in vibration in operation process, further influence is connected to the normal contact of spark plug end, will cause the malfunction of spark plug;
2. before arranging high voltage wire, high tension line support must be installed, if the fixing high tension line support of single-point must place the high tension line support pre-installed position and will prevent deflection in rundown process, so increased workman's workload on assembly line;
3. the amount of parts that relates to of the layout of high voltage wire is more, has promptly reduced system reliability and has increased cost again; Such as the processing charges that has increased high tension line support manufacture cost and valve chamber cover.
Summary of the invention
The purpose of this utility model provides a kind of valve chamber cover, and it has high voltage wire and contacts that reliable integrated type is arranged, characteristics simple in structure, easy for installation.Solve that high voltage wire reliably contacts and with the technical problem of cyclinder head cover integral arrangement.
The utility model is to solve the problems of the technologies described above to adopt following technological scheme: a kind of valve chamber cover, comprise cover cap, and on the housing outer surface of described cover cap, be provided with oil filler, crankcase ventilation hole, high voltage wire hole etc.; It is characterized in that: on described cover cap outer surface, also be provided with the device of tightening in adaptive spark-plug cable hole, describedly tighten device and described cover cap is made as one.
The described device of tightening is one group of wire casing.Described wire casing can be parallel form setting on cover cap.
For high voltage wire can be tightened by wire casing, the A/F of wire casing is less than the line footpath of high voltage wire, and the degree of depth is greater than the line radius of high voltage wire.
Tighter for what high voltage wire can be fixed, in the high voltage wire wire casing at least one ply-yarn drill can also be set, the ply-yarn drill A/F is less than the wire casing diameter.
Described high voltage wire wire casing one end flushes valve chamber cover, and the other end bends adaptive high voltage wire hole.
Good effect of the present utility model is, high tension line support and plastics valve chamber cover carried out integrated owing to adopt, and makes integrated type, reduced amount of parts and cost.Optimize the layout that high voltage wire covers at cyclinder head cover, arc groove is tightened the line footpath of the A/F of device form wire casing less than high voltage wire, and the degree of depth can be tightened high voltage wire by wire casing greater than the line radius of high voltage wire, and can tighten high voltage wire more by several places ply-yarn drill.Advantage is: high voltage wire is installed, safeguards, changes more easy, reduced the assembling work amount, increased high voltage wire arrangement length simultaneously, made connection and reasonable arrangement from the spark coil connecting end to the spark plug end, the vibration minimizing that gets loose has improved the normal contact reliability of high voltage wire and spark plug end simultaneously.Simple in structure.
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
