Abstract
The utility model relates to a novel oil seal structure for a front bearing cover of a double-clutch automatic transmission. The structure is characterized in that a front bearing oil seal is arranged in a groove of a front bearing cover assembly, made of a rubber material and provided with three holes; left and right holes are connected with clutch pressure control oil inlets; a middle hole is connected with a clutch lubricating and cooling oil inlet; and the joints of the front bearing oil seal and the clutch pressure control oil inlets, and the front bearing oil seal and the clutch lubricating and cooling oil inlet are sealed. By the structure, clutch pressure control oil and lubricating and cooling oil which flow into clutches can be prevented from leaking, and the number of sealing elements is reduced.
Description
Technical field
The utility model relates to a kind of novel double-clutch automatic transmission front bearing retainer oil seal structure, belongs to the automatic gearbox technical field of auto manufacturing.
Background technique
Along with the fast development of automobile pollution and the rapid increase of amateur driver's quantity, automatic gearbox is just presenting fast development trend.Present automatic gearbox mainly contains hydraulic mechanical type automatic transmission (AT), stepless speed variator (CVT) and double-clutch automatic transmission (DCT).
Realizing on automobile that the self-shifting speed changer is the hydraulic mechanical type automatic transmission, be called for short AT, also is present most widely used automatic gearbox.It does not cut off power shfit, has starting, gear shift is smooth-going, but resisting moment is changed advantage such as self adaption.But shortcomings such as it also has complex structure simultaneously, and difficulty is made, and transmission efficiency is low.
Manually fixedly the shaft type gear-shift transmission is the step change driving mechanism, and its advantage is that efficient is high, and cost is low, and mature production technology is widely used in China at present.Shortcoming is a gear shift difficulty, and power interruption during gear shift requires pilot control skilled, so people expect that it can realize automation.Computer Control Technology makes this gear realize that automaitc shfit becomes possibility.Double-clutch automatic transmission (DCT) is the automatic mechanical transmission of a new generation; It has inherited high, the many advantages such as installing space is compact, in light weight, low price of manual transmission transmission efficiency; Fundamentally solved the cut-out power shfit problem that electric control mechanical type automatic speed variator exists; Greatly improved the gear shift travelling comfort, guaranteed that vehicle has good power character and shift characteristic.
In double-clutch automatic transmission, each gear driving gear of speed changer by strange, even number gear respectively with input shaft on two clutch C1, C2 being provided be connected, clutch C1, C2 replace transferring power to realize gear switch.
During DCT work, with certain gear operation, electrical control unit of automatic transmission (TCU) is judged next gear that is about to the work of getting into according to the signal of related sensor to vehicle earlier; Because of this gear clutch separation transferring power not also,, mesh this gear in advance so instruction hydraulic control solenoid valve is controlled gear-shifting actuating mechanism very easily; When vehicle operating reaches shift point; The clutch separation that only need will work simultaneously with another clutch, then makes automobile go with next gear.In gearshift procedure, the power of motor constantly is passed to wheel all the time, so the gearshift procedure of accomplishing like this is a power shfit.Vehicle implementation timing, will improve the gear shift travelling comfort greatly, simultaneously guarantee that also vehicle has good and economic, aspects such as vehicle oil consumption and discharging are made moderate progress.
Summary of the invention
The purpose of the utility model provides a kind of novel double-clutch automatic transmission front bearing retainer oil seal structure, and two clutch pressure control oil and lubricating cooling oil leakage that it can prevent to flow into clutch have reduced the quantity of seal element.
The technological scheme of the utility model is achieved in that a kind of novel double-clutch automatic transmission front bearing retainer oil seal structure; It is characterized in that: the fore bearing oil sealing is installed in the front bearing retainer assembly groove; Process by rubber material; The fore bearing oil sealing has three holes, about two holes connect the clutch pressure control oil-in, intermediate hole connects clutch lubrication cold oil inlet, fore bearing oil sealing and clutch pressure control oil-in, clutch lubrication cold oil inlet joint seal.
It is simple in structure and easy for installation that the utility model good effect is that this Di of the Hao ﹑ Cheng of sealing effectiveness ﹑ Gong makes Ke Kao ﹑.

Fig. 1 is the structural drawing of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further description: a kind of novel double-clutch automatic transmission front bearing retainer oil seal structure; It is characterized in that: fore bearing oil sealing 1 is installed in front bearing retainer assembly 2 grooves; Process by rubber material; Fore bearing oil sealing 1 has three holes; About two holes connect clutch pressure control oil-in 3, intermediate hole connects clutch lubrication cold oil inlet 4, the 4 joints sealing that enters the mouth of fore bearing oil sealing 1 and clutch pressure control oil-in 3, clutch lubrication cold oil.
Fore bearing oil sealing 1 can prevent to flow into two clutch pressure control oil and lubricating cooling oil leakage of clutch, has reduced the quantity of seal element, has reduced technology difficulty, has the Hao ﹑ Cheng of sealing effectiveness this Di ﹑ reliable operation and characteristics such as simple in structure.
