Description
Technical field
The utility model is related to a kind of new double-clutch automatic transmission (DCT) rear covers to seal lubrication system, belongs to
In the Technology of Automatic Transmission for vehicle field of auto manufacturing.
Background technology
It is sharply increased with fast-developing and amateur driver's quantity of car ownership, automatic gearbox
It is positive that fast-developing trend is presented.Present automatic gearbox mainly has hydraulic mechanical type automatic transmission (AT), stepless
Speed changer (CVT) and double-clutch automatic transmission (DCT).
Most early on automobile realize fluid drive speed changer be hydraulic mechanical type automatic transmission, abbreviation AT and mesh
Preceding most widely used automatic gearbox.It does not cut off power shifting, has starting, smooth gear shifting, and the moment of resistance is changed
Can be adaptive the advantages that.But the shortcomings such as it also has complicated simultaneously, hardly possible manufacture, and transmission efficiency is low.
Fixed shaft type gear-shift mechanism is step speed change transmission mechanism manually, and advantage is efficient, at low cost, production work
Skill is ripe, is widely used at present in China.Shortcoming is that gearshift is difficult, power interruption during gearshift, it is desirable that pilot control is skilled, institute
With it is intended that it can realize automation.Computer Control Technology makes it possible that this gear realizes self shifter.It is double
Clutch type automatic transmission (DCT) is the automatic mechanical transmission of a new generation, it inherits manual transmission transmission efficiency
High, many advantages, such as installation space is compact, light-weight, cheap, fundamentally solves electric control mechanical type automatic speed variator
Existing cut-out power shifting problem, drastically increases shifting comfort, ensure that vehicle has good dynamic property with changing
Keep off characteristic.
In double-clutch automatic transmission, each gear driving gear of speed changer by odd, even several gears respectively with input
Two clutches C1, C2 connection set on axis, clutch C1, C2 replace passing power to realize that gear switches.
When DCT works, vehicle is first run with some gear, and electrical control unit of automatic transmission (TCU) is according to related sensor
Signal judge the next gear that will enter work, because of the also non-passing power of the gear clutch separation, therefore instruct hydraulic pressure control
Solenoid valve processed very easily controls gear shifting actuating mechanism, engages this gear in advance, when vehicle operation reaches shifting points, only
The clutch separation that will be being worked is needed, while another clutch is engaged, then automobile is made to be travelled with next gear.
In shift process, the power of engine is constantly passed to wheel always, so the shift process so completed changes for power
Gear.Vehicle realizes power shifting process, will greatly improve shifting comfort, while also ensures that vehicle has good economy
Property, vehicle oil consumption and discharge etc. is made to make moderate progress.
At present, the lubrication and cooling of each gear needle bearing and synchronizer friction pair rely on passive lubrication in fact more in speed changer
It is existing, i.e., gear oil is introduced into corresponding position by structures such as oil guide groove, Oil Guide muscle.The drawback is that the oil mass imported is unstable,
And it is respectively inconsistent by lubricating place lubricant effect, and back-end sealing is fixed by bolts back casing form more, installation steps are more.
The content of the invention
The purpose of this utility model is to provide a kind of new double-clutch automatic transmission (DCT) rear cover sealing lubrication
Structure, has simple and compact for structure, and easy for installation, lubricants capacity distribution is stablized, high lubricating effect and light-weight, at low cost
The features such as.
What the technical solution of the utility model was realized in：
A kind of new double-clutch automatic transmission rear cover sealing lubrication system, including Oil Guide disk, atomizer, oil inlet
Mouthful, Oil Guide disk is assembled with speed changer main casing, and Oil Guide disk is disk-like structure, and atomizer, oil inlet are integrated on disk-like structure
And oil leab, pressure oil enter oil leab from oil inlet respectively, and transmission input shaft is imported from atomizer, it is defeated to speed changer
Enter the needle bearing on axis and synchronizer is lubricated cooling.
Further, it is close to be equipped with the progress of twice annular bulge-structure for the cooperation position of the Oil Guide disk and speed changer main casing
Envelope.
Further, blanking cover is additionally provided between the Oil Guide disk and speed changer main casing, blanking cover passes through sealing lip and speed change
Device main casing back-end sealing connects, and carries out axial limiting using snap ring.
The utility model good effect is：Double-clutch automatic transmission (DCT) input shaft uses independent draw-off tray knot
Structure introduces pressure oil inside input shaft, and rear end is sealed with blanking cover, simple and compact for structure, easy for installation, lubricants capacity point
With stabilization, high lubricating effect and light-weight, at low cost.
Description of the drawings
Fig. 1 is the utility model structure diagram.
Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings：
A kind of new double-clutch automatic transmission (DCT) rear cover seals lubrication system, including Oil Guide disk 1, oil spout
Mouth 2, oil inlet 4, blanking cover 4 and snap ring 6, Oil Guide disk 1 and speed changer main casing assemble, and Oil Guide disk 1 is disk-like structure, and plate-like knot
Atomizer 2, oil inlet 3 and oil leab are integrated on structure, pressure oil is respectively from oil inlet 3 into oil leab, from atomizer 2
Import transmission input shaft；It is close that the progress of twice annular bulge-structure is equipped in the cooperation position of Oil Guide disk 1 and speed changer main casing
Envelope；Blanking cover 4 is additionally provided between Oil Guide disk 1 and speed changer main casing, blanking cover 4 is close by sealing lip 5 and speed changer main casing rear end
Envelope connection, and carry out axial limiting using snap ring 6.
The disk-like structure of the Oil Guide disk 1 of non-metallic material and main casing mates, and Oil Guide disk 1 is by oil inlet and atomizer
An entirety is integrated into using disk-like structure, is had the characteristics that compact-sized and easy for installation；Oil leab is integrated in plate-like knot
On structure, space availability ratio is high；After the assembling of Oil Guide disk 1 and main casing, oil inlet 3 connects housing mail gallery holes, and pressure oil is from oil inlet
Mouth 3 enters oil leab, imports input shaft by atomizer 2, cooling is lubricated to the needle bearing on input shaft and synchronizer,
So input shaft bore can obtain pressure stability and evenly distributed lubricating oil, and oil duct makes the flow direction of lubricating oil with oil spout mouth structure
It is all well controlled with flow, high lubricating effect.Twice annular protrusion is equipped in the cooperation position of Oil Guide disk 1 and main casing
Structure, plays the sealing function with main casing, and main casing rear end is packed into nonmetallic blanking cover 4 processed, is matched somebody with somebody by sealing lip 5 with main casing
Sealing is closed, and axial limiting is carried out using snap ring 6, it is simple in structure, it is easy for installation, it is at low cost.
