Description
Technical field
Become the present invention relates to vehicle mechanical mechanism, more particularly to a kind of new automobile fluid torque-converter and with the fluid power
The automobile of square device.
Background technology
The hydrodynamic unit that fluid torque-converter is made up of pump impeller, turbine, guide wheel.Fluid torque-converter is arranged on engine and change
Between fast case, using hydraulic oil as working media, play transmission torque, bending moment, speed change and clutch.
Exactly there is the presence of fluid torque-converter, automatic car stopping just can smoothly start to walk, and shift gears and move backward, can also be
Car is unlikely to engine misses when stopping.
Oil consumption always is an important indicator of automotive performance, and the phenomenon of current generally existing is, with a vehicle, phase
Same discharge capacity, manual gear is more fuel-efficient than automatic catch, and it is higher to be firstly because manual gear transmission efficiency, is between engine and gearbox
Realize that power is transmitted by clutch Hard link, and automatic catch vehicle is due to the presence of fluid torque-converter, mechanical energy was being transmitted
There is loss in journey, cause oil consumption higher than manual gear, but with the development of vehicle transmission technology, the locking scope of fluid torque-converter
Further (the hydraulic torque converter lockout scope as provisioned in certain vehicle is up to 89%, because fluid torque-converter is in locking for increase
Its transmission efficiency is identical with manual gear clutch, therefore its machinery driving efficiency is greatly improved) so that the oil consumption of automatic catch vehicle is obtained
Further to reduce, but still there are many gaps with manual gear vehicle, among these except fraction power caused by fluid torque-converter
Loss is outer, and remaining is exactly oil consumption gap caused by shift logic, but progress with fluid drive box technology and gear number
Increase, shift logic and the manual gear almost indifference, or even be also advantageous over manual gear of current automatic catch, because automatic catch gearbox
The revolution of speed and engine can be matched with more economical gear, then oil consumption actually also it is poor where
It was discovered by researchers that with money car in equal discharge capacity, the difference of automatic transmission vehicle and manual gear vehicle oil consumption is just poor
On sliding, particularly some veteran drivers open manual gear and can output the oil consumption lower than others, except can be more skilled
Operation clutch and gearshift outside, what they were more adept at is to allow vehicle sliding, is exactly veteran driver near red light road
Mouthful or when needing parking, they can pluck gear in advance or step on clutch relatively remote, make full use of the inertia of vehicle
Slide into red light crossing or need the position of parking, when vehicle sliding, engine and the unpowered connection of gearbox, hair

Exemplified by vehicle, it is assumed that the vehicle is travelled in accessible straight section, at 200 meters from traffic lights, speed is 40 kilometers/hour,
Manual gear vehicle can just pluck gear in advance, using coast to traffic light, and engine is in idling shape in taxiing procedures
State, is 800 revs/min or so, and automatic catch vehicle, then ability accelerator releasing at 40 meters away from traffic lights is arrived, at 160 meters of traveling
Between, engine running speed is general more than 1500 revs/min, if automatic catch vehicle shifts to an earlier date accelerator releasing, will be due to hair
Motivation braking action and speed is declined faster, to finally can only idling crawling to traffic light, take it is more, if but in order to
Maintain speed, then can only continue to step on the gas, anyway, as a result only can more excessive fuel consumption, loitered in city, manually and from
Dynamic oil consumption gap can be more obvious.In addition, at lower gentle slope, manual gear vehicle, which can pluck gear or step on clutch, utilizes vehicle
Gravity and inertia are ramped up by gentle slope, and automatic catch vehicle, because the gradient is smaller, due to starting in the case of not stepping on the gas
The braking action vehicle of machine can only idling crawling, it is necessary to which acceleration descending of stepping on the gas could obtain preferable speed.Therefore, if
It can slide, and the length of coasting distance is very big on the oil consumption of vehicle influence.
There is a kind of solution, exactly gearbox automatically switches to neutral gear, gearbox when driver unclamps throttle every time
The power that can be disconnected between engine and wheel is connected, and such vehicle can not just be influenceed and be slided by engine brake force；
When switching to neutral gear, the multiplate clutch in gearbox can be automatically separated, thus cut off power linking, but driven
In, it is frequently to operate very much that driver, which unclamps throttle, and multidisc clutch ceaselessly will be combined and separated, so to multiple-piece
Clutch causes larger abrasion, and needs whether car running computer unclamps judging throttle and perform to multiple-piece clutch among these
The control of device, is easier to be out of order, moreover transmission neutral is not appropriate for be designed when of short duration parking is with failure trailer
Frequent switching, and gearbox, once breaking down, its maintenance cost is very high.
So, how preferably to increase the coasting distance of automobile, so that the traveling oil consumption for reducing vehicle is art technology
The problem of personnel have to be solved.
The content of the invention

Fig. 1 is the structure of common fluid torque-converter, under normal circumstances, and pump impeller 2 is to be rigidly connected with housing 6, is filled inside it
Full hydraulic oil, housing 6 is rigidly connected with engine flywheel, and turbine 4 is rigidly connected by the first spline 7 with transmission input shaft,
Pump impeller 2 rotates turbine 4 by stirring hydraulic oil, and then gearbox is obtained power input.Lock-up clutch 5 by platen 51,
Friction plate 52 and damping disc 53 are constituted, and its effect is after speed reaches certain limit, housing 6 to be connected with turbine 4, so
The power of engine just can absolutely be delivered to gearbox, it is to avoid power loss, pressure caused by the agitation hydraulic oil of pump impeller 2
Disk 51 is hollow disk, and it can carry out axial displacement in the presence of oil pressure, and damping disc 53 is socketed in turbine by the second spline 8
On the spline of 4 behinds, and axial displacement can be carried out under the extruding of platen 51, when fluid torque-converter needs locking,
In the presence of oil pressure, platen 51 is moved right, and friction plate 52 is pressed together with damping disc 53 and housing 6, and power leads to
Cross housing 6 and pass to damping disc 53, turbine is then passed to by the second spline 8, gearbox is then passed to, locking work(is realized
Energy.
Specifically, in vehicle traveling process, when driver unclamps gas pedal, engine speed is begun to decline, automobile
In sliding state, if speed is higher, fluid torque-converter is in lockup state, then the bang path of engine brake force is shell
Body → lock-up clutch → turbine → gearbox → wheel.And if speed is relatively low, then fluid torque-converter is in released state, hair
Motivation brake force can be by stirring liquid during pump impeller → turbine by housing → pump impeller → turbine → gearbox → wheel
Force feed realize, it can be seen that no matter speed height, when the driver releases the brake pedal, the brake force of engine can all be transmitted
To wheel, speed is set to decline rapidly, (in automatic gear-box, indivedual gears have one-way clutch, but because volume and cost are limited
System, it is impossible to which each gear has one-way clutch, and has the gear of one-way clutch all in high tap position, although vehicle is in height
Gear can be slided with lower resistance, and speed decline is slower, but has once arrived low-grade location, and engine brake force can be intervened rapidly, and then
Speed is declined rapidly, coasting distance can be substantially reduced, and part gearbox there is also downshift pause and transition in rhythm or melody phenomenon).Although existing
There is towing astern oil-break technology (to refer in the case of release throttle, vehicle can drive engine to operate, in certain vehicle speed range in engine
Interior, engine can stop oil spout reducing oil consumption), but the engine brake force after oil-break is very big, and speed declines quickly, makes to slide
Distance is greatly shortened, and in order to maintain traveling, engine often recovers rapidly fuel feeding, so the oil-break time is very of short duration, in addition
Such as on some gentle slopes, automatic catch vehicle due to the influence of engine brake force, in the presence of accelerator releasing vehicle can only idling it is compacted
OK, descending of stepping on the gas therefore is even needed, but manual gear can pluck gear and engine disconnection is connected with the power of gearbox completely,
Engine is set to be in idling mode, vehicle can lean on gravity and the inertia glide downwards of itself, and speed increase is very fast and slides
Distance is longer, therefore, to increase the coasting distance of automatic catch vehicle and be held in the mouth it is necessary to power in time between cut-out engine and wheel
Connect.
Those skilled in the art can understand, want to realize the purpose of increase automatic catch vehicle coasting distance, one kind is to change
Enter automatic gear-box design, one kind is to improve fluid torque-converter design, and is sought to by improving Gearbox design all low
Fast gear all using one-way clutch (major part automatic gear-box is all to have one-way clutch in high tap position at present), makes vehicle exist
It can not also be influenceed during low speed slide by engine brake force, but increase one-way clutch in low gear, speed change can be caused
Case is redesigned, and increases gearbox volume, is increased design difficulty, is increased cost, and low gear is all using unidirectional
Clutch can make the slow drop disabler in the abrupt slope of part vehicle, because one-way clutch can not transmit the brake force of engine, and
And more one-way clutch, once being damaged in gearbox, its maintenance cost is very big, so scheme is unrealistic.
Another is exactly to redesign fluid torque-converter, it is automatically cut off engine and wheel in vehicle sliding
Between power linking, vehicle is not constrained by engine brake force, slide farther distance, and needing engine braking
When power (the slow drop function in such as abrupt slope), the brake force of engine can be delivered to wheel again, make vehicle deceleration.
In this application, described one-way clutch is also referred to as freewheel clutch, can also be called unilateral bearing, surmount axle
Hold, it is roughly divided into three kinds, respectively Wedge-type, roller oblique slot type, ratchet wheel pawl type, the load that wherein Wedge-type can be born
It is larger, be widely used in automobile gearbox, ratchet wheel pawl type one-way clutch in surmount state when have noise, such as from
Noise of the driving trailing wheel when sliding, roller oblique slot type one-way clutch can also realize the function of mono-directional overrun, but due to wedge
The load that block formula one-way clutch can be born is bigger, and does not have noise during work, and is widely used in vehicle transmission field, therefore
One-way clutch on turbine is using Wedge-type as prioritizing selection.
Fig. 2 is refer to, is the new automobile fluid torque-converter structural representation in one embodiment of the invention；
A kind of new automobile fluid torque-converter in the present embodiment, between the engine and gearbox of automobile, bag
Include：The closed work chamber that pump impeller 2, guide wheel 3, turbine 4 and housing 6 are connected as a single entity, the closed work chamber is filled with liquid
Force feed, the closed work chamber is installed with transmission input shaft, also included between the housing 6 and the turbine 4：One locking from
Clutch 5, to when vehicle reaches friction speed by the housing 6 and the locking of clutch plate 54/separate, in the turbine 4
An one-way clutch 10 is provided centrally with, the turbine 4 is connected by the one-way clutch 10 with the transmission input shaft,
The one-way clutch 10 can not be to identical with the pump impeller 2 relative to the transmission input shaft to limit the turbine 4
Direction of rotation rotate, but can freely be rotated to opposite direction of rotation.Because turbine 4 passes through one-way clutch 10 and gearbox
Input shaft is connected, and clutch plate 54 is rigidly connected by the first spline 7 with transmission input shaft, due to the limit of one-way clutch 10
System, turbine 4 can not be rotated relative to transmission input shaft to the identical direction of rotation of pump impeller 2, but can be to opposite rotation side
To freely rotating.So that novel hydraulic torque converter can automatically cut off engine brake force pair when driver unclamps throttle
The influence of vehicle, enable the vehicle to using the farther distance of the coast of itself without in order to prevent vehicle reduction of speed too fast and
