Description

Wet-type double clutch connecting device
Technical field
Wet-type double clutch connecting device is the performance test that is used for the wet-type dual-clutch assembly of DCT (DSG) automatic transmission, the power transmission connecting mechanism that product detects, and belongs to vehicle test and detection range.
Background technology
At present, along with the fast development of trailer reversing robotization, automatic gearbox is just presenting flourish trend.The electric control mechanical type automatic speed variator (AMT) that present automatic gearbox mainly contains hydraulic mechanical type automatic transmission (AT), buncher (CVT) and exerting both at home and abroad in recent years to study.The particularly development of electric control mechanical type automatic speed variator because it has the advantage of the existing manual transmission production investment of the desired high fuel economy of present automobile industry development, low emission and protection, has been subjected to the attention of each big automobile factory.
Yet, in development research, also found its some shortcomings gradually to electric control mechanical type automatic speed variator, its principle of work has determined it at first to want cut-off clutch in shift process, then variator is plucked neutral, block selecting again, gearshift, last engaging clutch.Like this, when after the clutch separation before clutch coupling engages again again, the power of engine can not be passed to wheel and go the powered vehicle operation, so produced the interruption of transmission of power in the shift process, vehicle certainly leads to retarded velocity, the gearshift time is long, brings adverse effect for the acceleration, comfortableness etc. of vehicle.
DCT (DSG) automatic transmission has two clutch couplinges, in gearshift procedure, two clutch couplinges all participate in work, the engaging process of the detachment process of the clutch coupling of working and the clutch coupling that will work carries out simultaneously, therefore power output is not interrupted, improve gear shifting quality greatly, obtained application more and more widely.The wet-type dual-clutch assembly is the main topworks of DCT (DSG) automatic gearbox gear shifting process, belongs to critical component, is absolutely necessary and test in each links such as the exploitation of wet-type dual-clutch assembly, production.This device is exactly the power transmission connecting mechanism that detects according to the performance test of this requirement exploitation, product.
Summary of the invention
The difference of wet-type dual-clutch assembly and conventional dry clutch coupling is that friction disc is two groups of multi-discs, and two power outputs are arranged.During real work, the wet-type dual-clutch assembly is sealed in automatic transmission inside, and friction disc is immersed in the lubricating oil.Performance test, the product of making the wet-type dual-clutch assembly detect, and can not be placed on the car load and do, and that can make experimentation too complicated, and testing expenses increase greatly, also do not meet development process.Therefore must simulate the actual working environment of this assembly, design one cover power transmission connecting mechanism is to carry out bench test easily.The objective of the invention is to for addressing the above problem, it is Wet-type double clutch connecting device that a kind of power coupling arrangement that is used for the test of wet-type dual-clutch assembly is provided.
Above-mentioned purpose of the present invention is achieved in that accompanying drawings is as follows:
Wet-type double clutch connecting device of the present invention comprises input shaft 1, output shaft, housing 3 and sleeve 4; Have the spline that is connected with wet-type dual-clutch input end spline on the said input shaft 1; Said housing 3 two ends are equipped with input end housing 2 and output end housing 5 and are adopted the seal point sealing, and the center pit and the input shaft 1 of input end housing 2 are clearance fit, and seal by O-ring seal; Said sleeve 4 is sleeved on the oil groove of wet-type dual-clutch assembly output terminal, has the control oilhole on it, and output has the control oilhole corresponding with sleeve 4 and cooling, oil passage on the end housing 5, and output end housing 5 is by 7 sealings of output end cap; Said output shaft comprises first output shaft 6 and second output shaft 9 that links to each other with two splined hub of wet-type dual-clutch assembly output terminal respectively.
Said first output shaft 6 is a quill, and the one end links to each other with a splined hub of wet-type dual-clutch assembly output terminal, and the other end links to each other with wheel of the law dish 8, and wheel of the law dish 8 links to each other with shaft coupling again; Second output shaft 9 is a solid shaft, and the one end links to each other with another splined hub of wet-type dual-clutch assembly output terminal, and the other end directly links to each other with shaft coupling 8.Open a seal groove on second output shaft, by realizing sealing between the O-ring seal and first output shaft.
Said sleeve 4 is a copper sheathing, and it and wet-type dual-clutch assembly output terminal are clearance fit.
This product has following characteristics as power transmission and hydraulic channel in process of the test:
1, simple in structure, this device has replaced various variators and powerdriven bindiny mechanism in process of the test, has reduced the complexity of structure greatly, is convenient to so very much production and processing and test installation.Thereby reduction experimentation cost has improved test efficiency.
2, can improve test accuracy, because this apparatus structure is small and exquisite, easily processing, axially span is short, has reduced the distortion that produces because of self gravitation.
3, oil circuit is succinctly unobstructed, and the leakage link is few, has effectively avoided the leakage of the pressure oil of each link in the test.
4, easy to connect, the front and back of transmission shaft all are that the key connection is connected with wheel of the law dish, so can be applied to test very easily.
5, versatility is good, only needs relative dimensions is carried out the test that convergent-divergent just can be applied to various double clutches.
