Abstract
A kind of electromagnetic dual-clutch, construction are made of driving shaft, driving disc spacing pressing, first driven shaft, the first driven disc, second driven shaft, the second driven disc, coil case, coil, bell housing, coil fixed disk.Working principle: when the coil is not energized, coil is without magnetic field, without magnetic force between driving disc spacing pressing and driven disc；The power of driving disc spacing pressing cannot pass on driven disc, be equivalent to clutch "Off".When closing first coil control switch, first coil is powered, and first coil generates magnetic field；The power of driving disc spacing pressing is passed on the first driven disc by magnetic force, and power can be reached to the odd number shelves of speed changer.When disconnecting first coil control switch, the second coil control switch is closed, the second coil is powered, and the second coil generates magnetic field；The power of driving disc spacing pressing is passed on the second driven disc by magnetic force, and power can be passed to the even gear of speed changer.
Description
Technical field
The present invention relates to the clutches in a kind of car transmissions.
Background technique
Dual-clutch transmission is being used by more and more automobiles by its excellent performance.Double clutch speed change
The clutch of device generally uses frictionally；But this clutch is worn when in use than very fast, the service life is shorter, has been seriously affected double
The reliability of clutch speed-changer work.
Summary of the invention
The object of the present invention is to provide a kind of electromagnetic dual-clutch；The clutch generates magnetic force by electromagnetic coil, leans on
The driving and driven part of double clutch is linked together and transmits power by magnetic force.Compared with slip clutch, structure is simple, work
Make reliable.
Construction of the invention is by driving shaft, driving disc spacing pressing, first driven shaft, the first driven disc, second driven shaft, second driven
Disk, coil case, coil, bell housing, coil fixed disk and magnetic shield composition.Wherein, one end of driving shaft is screwed
On engine flywheel；Driving disc spacing pressing is circular ring shape, is manufactured with aluminium alloy；It is formed with a pair of of driving disc spacing pressing the first magnetic conduction ring gear and one thereon
To driving disc spacing pressing the second magnetic conduction ring gear；In addition, having the equally distributed driving disc spacing pressing of a circle between two driving disc spacing pressing the second magnetic conduction ring gears
The quantity of magnetic inductive block, driving disc spacing pressing magnetic inductive block is equal with the magnetic conduction ring gear number of teeth；Driving disc spacing pressing is mounted on driving shaft by spline.First
Driven disc is disc, is manufactured with aluminium alloy；Thereon embedded with an equally distributed first driven disc magnetic inductive block of circle, magnetic inductive block across
Driving disc spacing pressing the first magnetic conduction ring gear forms a pair of of air gap；First driven disc is fixed in first driven shaft.First driven shaft is cylinder
Shape covers in second driven shaft.Second driven disc is manufactured with aluminium alloy；It is led thereon embedded with two equally distributed second driven discs of circle
Magnetic patch, the second driven disc magnetic inductive block is across driving disc spacing pressing the second magnetic conduction ring gear and driving disc spacing pressing magnetic inductive block；Second driven disc is fixed on
On two driven shafts.First coil is identical with the second loop construction, and first coil and the second coil case are circular ring shape, uses low-carbon
Steel making, as the iron core of respective coil；Annular portion position is opposite with magnetic conduction ring gear on driving disc spacing pressing respectively on the right side of coil case, and has
Certain gap.Coil case is fixed in coil fixed disk；Coil fixed disk is screwed on IC engine airframe.
Working principle: when internal combustion engine, flywheel drives driving shaft and driving disc spacing pressing rotation；When the coil is not energized, coil
Without magnetic field；Pass through between driving disc spacing pressing magnetic inductive block, driving disc spacing pressing magnetic conduction ring gear and driven disc magnetic inductive block without the magnetic line of force, driving disc spacing pressing with from
Without magnetic force between Moving plate；The power of driving disc spacing pressing cannot pass on driven disc, be equivalent to clutch "Off".
It is powered when to first coil, first coil generates magnetic field；The magnetic line of force passes through first coil shell → driving disc spacing pressing first
Magnetic conduction ring gear → the first driven disc magnetic inductive block → the first magnetic conduction of driving disc spacing pressing ring gear → first coil shell constitutes closed circuit；In master
The magnetic force to attract each other is generated at Moving plate the first magnetic conduction ring gear and the first driven disc magnetic inductive block air gap, and generates eddy current electromagnetic；
The power of driving disc spacing pressing is passed on the first driven disc by magnetic force, and power can be reached to the odd number shelves of speed changer；When driving disc spacing pressing, driven
Eddy current electromagnetic disappears when disk rotating speed is identical.
When first coil powers off, and the second coil is powered, the second coil generates magnetic field；The magnetic line of force passes through the second coil case
The second magnetic conduction of → driving disc spacing pressing ring gear → the second driven disc magnetic inductive block → driving disc spacing pressing magnetic inductive block → the second driven disc magnetic inductive block → active
The second magnetic conduction of disk ring gear → second coil case constitutes closed circuit；The second magnetic conduction of driving disc spacing pressing ring gear, driving disc spacing pressing magnetic inductive block with
The magnetic force to attract each other is generated at second driven disc magnetic inductive block air gap, and generates eddy current electromagnetic；The power of driving disc spacing pressing passes through magnetic
Power reaches on the second driven disc, and power can be reached to the even gear of speed changer.
Power is transmitted since the clutch links together driving and driven part by magnetic force；Compared with slip clutch,
It works more reliable.
