Shape, small head end are provided with external thread section.The stub end of vavuum pump drive sub passes through a disk transition with small head end.Vavuum pump drives
The port of dynamic joint stub end is provided with connector, and the oil duct of three sections of different-diameters is provided with along the axial line of vavuum pump drive sub.
Vavuum pump drive sub main body is a tommyhead bolt, for the cam shaft gear on tightening cam axle, the spiral shell of bolt
Cap (stub end) is designed as yi word pattern keyway, for driving vavuum pump.So one of bolt connection camshaft (and fix simultaneously
Cam shaft gear)；An other connection vavuum pump.Lubricating oil in camshaft is supplied to vavuum pump by internal hollow passageway,
For vacuum pump lubrication.
The characteristics of the utility model and beneficial effect are：Joint is according to the specific space structure of engine and vavuum pump company
Connect mode and carry out " seizing every opportunity " formula and be designed, can both maintain engine machine shape size to be basically unchanged, fill again
Divide and enter action edge transmission using camshaft, make engine structure compact.Vavuum pump drive sub provides installation for cam shaft gear
Fastening, provides drive connection, while provide lubricating oil for vavuum pump for vavuum pump.This vavuum pump drive sub is tight as installation
Gu, drive connection, provide the connection member that is integrated of lubrication, there is the characteristics of simple in construction, practicality is high.
