Abstract

The utility model relates to a novel double clutch type automatic transmission oil guide duct structure, which consists of a rear cover, an output shaft and a bush, and is characterized in that the rear end of the output shaft is connected with the rear cover; and the inner side of the rear cover is provided with two oil guide ducts of which the front ends extend to the end face of the rear cover and the rear ends extend to a spline bush of the rear part of the rear cover along the inner wall. The novel double clutch type automatic transmission oil guide duct structure has a simple structure and a good lubricating effect.

Description

A kind of novel double-clutch automatic transmission Oil Guide oil channel structure

Technical field

The utility model relates to a kind of novel double-clutch automatic transmission Oil Guide oil channel 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 gear shifting, has starting, smooth gear shifting, but to advantages such as resisting moment variation self adaptions.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 gearshift difficulty, and power interruption during gearshift requires pilot control skilled, so people expect that it can realize automation.Computer Control Technology makes this gear realize that self shifter 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 gear shifting problem that electric control mechanical type automatic speed variator exists; Greatly improved shifting comfort, guaranteed that vehicle has good power character and gear shifting 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 and switch to realize gear.

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 gearshift actuator very easily; When vehicle operating reaches shifting points; The clutch separation that only need will work simultaneously with another clutch, then makes automobile go with next gear.In shift process, the power of motor constantly is passed to wheel all the time, so the shift process of accomplishing like this is a power gear shifting.Vehicle implementation the power gear shifting process, will improve shifting 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 Oil Guide oil channel structure, and Ju has Jie structure Jian Dan ﹑ high lubricating effect.

The technological scheme of the utility model is achieved in that a kind of novel double-clutch automatic transmission Oil Guide oil channel structure; Form by bonnet, output shaft, lining; It is characterized in that: the output shaft rear end of speed changer connects bonnet; The bonnet inboard has two Oil Guide oil ducts along inwall, its front end to bonnet end face, rear end to back postoperculum spline lining place.

The utility model good effect is that Ju has Jie structure Jian Dan ﹑ high lubricating effect.

Description of drawings

Fig. 1 is the structural drawing of the utility model.

Fig. 2 is the Oil Guide oil duct layout plan of the utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is done further description: like Fig. 1, shown in 2; A kind of novel double-clutch automatic transmission Oil Guide oil channel structure; Be made up of bonnet 1, output shaft 2, lining 3, it is characterized in that: output shaft 2 rear ends of speed changer connect bonnet 1, and bonnet 1 inboard has two Oil Guide oil ducts 4 along inwall; Its front end to bonnet 1 end face, spline lining 3 places, rear end to bonnet 1 rear portion.

During work; Because rotatablely moving of output shaft 2 is thrown to the lubricant oil in the part axis hole on the housing Oil Guide oil duct 4 through the radial hole on the axle; Lubricant oil will flow to lining 3 places along Oil Guide oil duct 4; Flow to output shaft 2 spline places through the aperture on the lining 3 again, play the effect of lubricated free-sliding spline, solved output shaft spline and the problem that can't obtain lubricate far away preferably apart from lubricant oil.Ju has Jie structure Jian Dan ﹑ high lubricating effect and the low characteristics of cost.

Claims

1. novel double-clutch automatic transmission Oil Guide oil channel structure; Form by bonnet, output shaft, lining; It is characterized in that: the output shaft rear end of speed changer connects bonnet; The bonnet inboard has two Oil Guide oil ducts along inwall, its front end to bonnet end face, rear end to back postoperculum spline lining place.
