Machine and Flexplate coupling, wherein the wheel to be traditional two panels wheel and an axle to being made of；It is described driving motor be
The permanent-magnet synchronizing traction motor of known rotor hollow shaft structure, its axial line and axle axial line arranged concentric；The flexibility
Plate shaft coupling is innovative technology, it is with big elastic deformation and without wear characteristic.The transmission mechanism drives motor output end with scratching
Property plate shaft coupling one end connect firmly, the Flexplate coupling other end couples with axle elastic conjunction, and attachment can be known " end
Face tooth+bolt " or " power transmission pin+bolt " draw bail.
The Flexplate coupling by power transmission flange one, flex plate one, the flanged (FLGD) hollow shaft in one end, power transmission flange two,
Flex plate two, power transmission core disk and attachment bolt composition.
The power transmission flange one is the annular flange of four notches, and its one end sets the end face connected firmly with driving motor output end
Tooth and bolt-connection hole.
The flex plate one is made of the ring stainless steel thin slice of eight notches, has elastic deformation, without abrasion, non-maintaining spy
Property, while bolt-connection hole is set.
The hollow shaft is hollow structure, and its one end sets four notch flanges (with flange one), and the other end is set and power transmission
The end-tooth and bolt-connection hole that flange two connects firmly.
The power transmission flange two is the annular flange of four notches, and its one end sets the end-tooth and bolt connected firmly with hollow shaft
Connection holes (similar power transmission flange one).
The flex plate two by eight notches ring stainless steel thin slice, have elastic deformation, without abrasion, non-maintaining characteristic,
Bolt-connection hole is set at the same time.
The power transmission core disk is the annular flange of four notches, its endoporus couples with axle, while sets bolt-connection hole.
Between the power transmission flange one, flex plate one, hollow shaft and between power transmission flange two, flex plate two, power transmission core disk
Connection can use the combination of bolt+nut.
To sum up, the Flexplate coupling has big elastic displacement capabilities and without wear characteristic, therefore the transmission mechanism is not
It is each to displacement demand under dynamic and static operating mode between only to adapt to the opposite wheel of driving motor, and because no abrasion are not required to
Lubrication, extends the non-maintaining cycle.In addition, each parts design is simple in structure, and uses the attachment of " end-tooth+bolt ",
So that processing and dismounting process are good.
