Abstract
The utility model relates to a novel lubricating structure for a double-clutch type automatic transmission output shaft, which is composed of the output shaft, a patch and a seal ring, and is characterized in that an opening is formed at the upper end of the output shaft, the patch takes the shape of a bowl and is provided with an opening at the top end, and the patch is hermetically connected with the opening of the output shaft through the seal ring. The novel lubricating structure ensures that the output shaft can obtain enough lubricating oil amount, and has the characteristics of simple structure, convenience for installation and excellent lubricating effect.
Description
Technical field
The utility model relates to a kind of novel double-clutch automatic transmission output shaft lubricating 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 output shaft lubricating structure, and it guarantees that output shaft obtains enough lubricants capacities, and Ju has the Jie structure Jian Dan ﹑ characteristics with high lubricating effect easy for installation.
The technological scheme of the utility model is achieved in that a kind of novel double-clutch automatic transmission output shaft lubricating structure; Form by output shaft, patch, seal ring; It is characterized in that: output shaft upper end perforate; Patch is a bowl type top perforate, and match sheet and output shaft tapping are tightly connected through seal ring.
The utility model good effect is simple in structure, easy for installation and high lubricating effect.
Description of drawings
Fig. 1 is the structural drawing of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation: as shown in Figure 1; A kind of novel double-clutch automatic transmission output shaft lubricating structure; Form by output shaft 1, patch 2, seal ring 3; It is characterized in that: output shaft 1 upper end perforate, patch 2 is a bowl type top perforate, and match sheet 2 is tightly connected through seal ring 3 with output shaft 1 tapping.
During work, lubricants capacity is controlled by hydraulic module, has lubricated sufficient characteristics, and lubricant oil guarantees that through the patch hole two cone bearings of output shaft 1 obtain enough lubricants capacities and cooling oil mass.O type circle 3 guarantees that lubricant oil can not leak, and guarantees lubrication effect.
