Abstract
The utility model relates to a novel dual clutch transmission (DCT) front bearing retainer assembly, which consists of a front bearing retainer, an oil seal, a steel ball and a bushing, and is characterized in that the bushing is in interference fit with the front bearing retainer; the front bearing retainer is provided with two clutch pressure oil holes and a clutch lubricating oil hole; and the oil seal is arranged on the front bearing retainer. The novel DCT front bearing retainer assembly has the characteristics of simple structure, convenience for installation, low cost and reliable operation.
Description
Technical field
The utility model relates to a kind of novel double-clutch automatic transmission (DCT) front bearing retainer assembly, 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 assembly, and its Ju has the Jie structure Jian Dan ﹑ An dress Fang Bian ﹑ characteristics with reliable operation with low cost.
The technological scheme of the utility model is achieved in that a kind of novel double-clutch automatic transmission front bearing retainer assembly, is made up of front bearing retainer, oil sealing, steel ball and lining, it is characterized in that: lining and front bearing retainer adopt interference fit; Front bearing retainer is provided with two clutch pressure oilholes and a clutch lubrication oilhole, and oil sealing is installed on the bearing cap.
The utility model good effect is that Ju has the Jie structure Jian Dan ﹑ An dress Fang Bian ﹑ characteristics with reliable operation with low cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model patent is done further description: a kind of novel double-clutch automatic transmission front bearing retainer assembly; Be made up of front bearing retainer 1, oil sealing 2, steel ball 4 and lining 3, it is characterized in that: lining 3 adopts interference fit with front bearing retainer 1; Front bearing retainer 1 is provided with two clutch pressure oilholes and a clutch lubrication oilhole, and oil sealing 2 is installed on the front bearing retainer, guarantees that cutting oil does not flow out front bearing retainer (1).
As shown in Figure 1, the lubricant oil that provides by oil pump through filtration and cooling after, distribute to pressure oil mass and the lubricating cooling oil amount of clutch by the DCT control module, pass through the oil duct of front bearing retainer 1 and 4 little oilholes on the lining 3 and offer clutch.The size in three apertures on the front bearing retainer 1 is by clutch pressure oil and the decision of lubricating cooling oil flow.
