Abstract
The utility model discloses a novel dual clutch transmission self -locking pin and control valve block integrated morphology, including control valve block, self -locking pin, the shift fork of shifting, control valve block, self -locking pin, the shift fork of shifting are all fixed on gearbox housing, and with the self -locking pin integration in control valve block. Self -locking mechanism and control valve block are integrated integrative, make self -locking mechanism's structure simplify greatly, and the compactness is wholly arranged to the bulk reduction, realizes the modularization for assembly speed, save the process of the space layout demand of self -locking pin on the casing and alone assembly.
Description
Technical field
This utility model relates to a kind of novel double-clutch automatic transmission (DCT) self-lock pin and control valve
Block integrated morphology, belongs to the Technology of Automatic Transmission for vehicle field of auto manufacturing.
Background technology
Along with the sharply increasing of fast-developing and amateur driver's quantity of automobile pollution, automobile is automatic
Variator is just presenting the trend of fast development.Present automatic gearbox mainly has hydraulic mechanical type automatic
Variator (AT), buncher (CVT) and double-clutch automatic transmission (DCT).
Realizing self-shifting variator on automobile is hydraulic mechanical type automatic transmission, is called for short AT,
Also it is current most widely used automatic gearbox.It does not cut off power shifting, has starting, gearshift
Smooth-going, can the advantage such as self adaptation to moment of resistance change.But it also has structure complexity, difficult manufacture, passes simultaneously
The shortcomings such as efficiency of movement is low.
The most fixing shaft type gear-shift mechanism is step speed change drive mechanism, and its advantage is that efficiency is high, low cost,
Mature production technology, is widely used in China at present.Shortcoming is gearshift difficulty, and power interruption during gearshift is wanted
Ask pilot control skilled, so it is intended that it can realize automatization.Computer Control Technology makes this change
Speed mechanism realizes self shifter and is possibly realized.Double-clutch automatic transmission (DCT) is the machinery of a new generation
Formula automatic transmission, it inherits, and manual transmission transmission efficiency is high, installing space is compact, lightweight, valency
Lattice cheaply wait many advantages, and the cut-out power fundamentally solving electric control mechanical type automatic speed variator existence changes
Gear problem, drastically increases shifting comfort, it is ensured that vehicle has good dynamic property and gear shifting characteristic.
In double-clutch automatic transmission, variator each gear driving gear is by odd, even several gears respectively
Being connected with two clutches C1, the C2 arranged on power shaft, clutch C1, C2 alternately transmission power is with reality
Existing gear switching.
During DCT work, vehicle first runs with certain gear, and electrical control unit of automatic transmission (TCU) is according to phase
The signal closing sensor judges to enter next gear of work, because this gear clutch separation is not also transmitted
Power, therefore instruction hydraulic pressure controlling solenoid valve controls gear shifting actuating mechanism very easily, engages this gear in advance
Position, when vehicle operation reaches shifting points, it is only necessary to the clutch separation that will working, simultaneously by another
Individual clutch engages, then make automobile travel with next gear.In shift process, the power of electromotor begins
Constantly it is passed to wheel, so the shift process so completed is power shifting eventually.Vehicle achieves dynamic
Power shift process, will improve shifting comfort greatly, also ensure that vehicle has good economy simultaneously,
The aspect such as vehicle oil consumption and discharge is made to make moderate progress.
Shift control mechanism completes gearshift function in the transmission, is mainly made up of shift fork and fork shaft, double clutches
Device formula automatic transmission (DCT) selector fork does not require nothing more than has enough rigidity and intensity, and needs
During gearshift, flexibly, frictional force is little in motion, and then reduces gear shifting force.Common self-locking mechanism is on variator
It is respectively mounted self-lock pin to match with shift fork, need to individually assemble, and self-lock pin needs bigger on housing
Arrangement space.
Summary of the invention
The purpose of this utility model is to provide a kind of novel double-clutch automatic transmission self-lock pin and control valve
Block integrated morphology, has that compact conformation is easy for installation, the feature of reliable operation.
The technical solution of the utility model is achieved in that
A kind of novel double-clutch automatic transmission self-lock pin and control valve block integrated morphology, including control valve
Block, self-lock pin, selector fork, control valve block, self-lock pin, selector fork be each attached on case of transmission,
And self-lock pin is integrated in control valve block.Self-locking mechanism is integrated with control valve block, saves self-lock pin and exists
Demand and the operation of individually assembling are arranged in space on housing.
Further, spring and the steel ball of mutually abutting it is provided with in described self-lock pin, on steel ball and shift fork axle
Groove fit, carries out spacing to selector fork.
Self-locking mechanism is integrated on valve block assembly, makes the structure of self-locking mechanism be greatly simplified, and volume reduces, whole
Body characteristics of compact layout, it is achieved modularity, accelerates assembling speed, improves efficiency, makes whole control and gearshift behaviour
Vertical mechanism becames one completely.
Accompanying drawing explanation
Fig. 1 is this utility model structure chart.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described:
As it is shown in figure 1, a kind of novel double-clutch automatic transmission self-lock pin and control valve block integrated morphology,
Including control valve block 1, self-lock pin 2, selector fork 3, control valve block 1, self-lock pin 2, selector fork 3 are equal
It is directly anchored on case of transmission, and self-lock pin 2 is integrated in control valve block 1.Set in self-lock pin 2
There are spring and the steel ball of mutually abutting, steel ball and the groove fit on shift fork axle, shift fork is carried out spacing.By
In self-lock pin 2 is integrated in control valve block 1, so assemble the tightst with selector fork 3, save speed change
Arrangement space in device, saves the assembly process of follow-up self-lock pin.
