Technical field
The present invention relates to a kind of vehicle drive system bidirectional automatic clutch.
Background technique
Currently, used clutch is in the majority with friction disk type on vehicle, it may be said that it has preferable reliability, energy
It is enough to complete expected service life.But unfortunately it can only constantly export engine power, but cannot for a long time by
Power cut.Also there can be no exception whatever for automatic transmission vehicle including higher gears time, it also can only be to divide clutch in the moment of gear shift
From or two clutches be used alternatingly.In short, such clutch can not cut off power for a long time.It is this when can not be long
Between cut off or the case where separation power, the linkages of some unnecessary periods will certainly be brought to the vehicle in traveling.Facts proved that
When vehicle stops accelerating, due to the power linkage that above-mentioned clutch is this unconditionally, lasting, it is impatient to directly result in vehicle inertial
Play decline, significantly reduces that vehicle is due to slide mileage.More seriously, all transmission devices being in linkage also wrap
Including engine is that coupled situation is forced in pressing, this undoubtedly will increase above-mentioned all abrasion, increase the noise in vehicle driving.
This unnecessary linkage can give automobile energy-saving emission reduction, guarantee that the service life of each part of vehicle causes greatly to injure.
Summary of the invention
The present invention be directed to the defect of above-mentioned conventional clutch, provided a new-type product.It can be effectively double
To conveying power, and in time power can be separated according to needed for the operating condition in vehicle driving, vehicle is really made to realize that energy conservation subtracts
Row reduces vehicle driving noise, elongate member service life.
Bidirectional automatic clutch includes driving disc spacing pressing, it and power input shaft connecting mode may be selected keyed and insert or be made as one
Body.Its periphery design has several special-shaped levels low in middle high side, to as roller rack.The disk one side prominent one
Opposite path is the carrier of support spring installation.
As the main part mid-game of this structure, it is sleeved on driving disc spacing pressing periphery, it is characterized in that: its base shape is tubular, circle
Week design has several roller bearing bore of perforation shell wall, which is rectangle, and quantity is identical as used roller and equidistant equal
Point, the orientation in hole is corresponded to each other with the roller rack of active panel surface.The mid-game is in driving disc spacing pressing and driven disc together together with roller
Between, internal diameter is slidably matched with driving disc spacing pressing major diameter, outer diameter assembly alternate with driven disc, and there are a path necking and active in side
Disk path is equipped.The effect of mid-game is to carry roller and guarantee equidistantly existing and move synchronously for roller.Meanwhile it undertakes receiving
Carry out the gravitation of self-magnetization semi-disc, drives roller displacement to change power direction of transfer.
Another main part of this clutch is driven disc, its internal diameter is in round mouth basin shape, and space contains driving disc spacing pressing, mid-game and rolling
Column.The dish external diameter is rule circle, and core necking is that interior keyhole is integrated with power output shaft dress.The effect of driven disc is will actively
The power of disk and roller is transferred to power output shaft.
Roller of the boundary between clutch driving plate and driven disc, it is the two disks intermediary clutch part, and inner end is along master
The track movement that Moving plate provides, by the positioning and control of mid-game, outer end and driven disc internal diameter are separation and reunion at middle part.
The automatic control unit of this clutch, including magnetization semi-disc, electromagnetic switch and switch plunger.When electromagnetic switch is logical
When electric, switch plunger and magnetization semi-disc i.e. can be mobile to mid-game flank, the disk after magnetization semi-disc magnetic force attracts mid-game
Understand relativity stalling and angular transition occurs, driving disc spacing pressing and driven disc is made reversely to combine transmitting power.
Already described this clutch driving plate and mid-game is slidably matched, and the angle change of mid-game is to be with the major diameter of driving disc spacing pressing
Axis.That is, the internal diameter of mid-game is greater than active dish external diameter in design, the two can be with rotational slide.On driving disc spacing pressing
Roller rack and deep cuts, the two disk spacing of portion made is bigger, but inserting because of roller, and there have been two dish gap interference not
It obtains and mutually rotates, the sliding of two disks has just been limited within driving disc spacing pressing roller rack region.Again because of the effect of support spring, it
Using driving disc spacing pressing as fulcrum, the other end supports mid-game for one end, its elastic force pushes mid-game and servo-actuated roller actively in driven disc
The A point of disk roller rack, meets the conjugation condition of driving disc spacing pressing and driven disc by roller.
As a kind of improvement and skill upgrading, the present invention is tying compared with traditional one-way driver or freewheel clutch
Structure and the difference for functionally having matter.Why this product is referred to as meaning bidirectional automatic clutch, be because it have two kinds it is two-way dynamic
Power transfer function, and be automation control.First is that its two-way binding function, i.e., reversed positive exportable power, make vehicle
Meet the needs (this is that one-way driver does not have) of front and back traveling second is that it has the function of two-way separation, i.e. vehicle inertia
The reverse actuating force to engine generated under state, this clutch can be isolated in time, and either vehicle advances or falls
Vehicle is such.Have the function of that the meaning of this two-way combinable, two-way separable power is: electric car installation in this way
This product, showing as the positive and negative both direction of motor can be moved ahead and be moved backward to complete it with output power.When electric car stops
When only accelerating, this clutch can separate the power linkage between motor, speed changer or retarder and drive axle in time, make electronic
All, machine etc. stops operating, and significantly reduces above-mentioned part because of the noise for wearing and generating caused by rotation, also therefore improves
The traveling inertia of electric car increases mileage travelled and saves electric energy.Conventional vehicles in this way install this clutch, and clutch function is theoretical
On see and have no big difference with electric car.But for reality, when conventional vehicles stop acceleration, resistance caused by engine
Motor is much larger than to the inertia effects degree of vehicle.Exactly the above-mentioned linkage of electric car is small torque cooperation connection
It is dynamic；And conventional engine automobile is large torque pressing linkage, this laminated type links to transmission system and engine bring mill
It is huge for damaging evil.Furthermore the forfeiture of vehicle inertia is made to energy waste caused by vehicle to be also immeasurable.Above-mentioned vehicle
Installation this product after, i.e., can avoid the generation of above-mentioned negative drawbacks.
As an extraordinary design, to meet the special operation condition of vehicle.When automobile is in lower long slope, steep slope road section when driving,
Traffic law requires must have the attached safety for helping vehicle of engine braking.For this purpose, this product has been specifically designed as described above automatically
Control device implements this clutch and interacts with brake electronic signal instruction (or other associated mechanicals) impeller, so as to reality
The now combination under this clutch specific condition, to ensure presence of the engine braking under above-mentioned road conditions.
As described above, function of the present invention is original, solve the related problem that vehicle is attended to one thing and lose sight of another for a long time, has taken into account point
From power and retain necessary engine braking unity of contradictions between the two, and this implementation is included in automation control
Among, this product also has design concurrently rationally, and the advantages such as easy for installation can bit selecting on transmission for vehicles or retarder, drive axle
Installation.

Specific embodiment
As shown in Figure 1, this bidirectional automatic clutch, including driving disc spacing pressing 9, core are that interior formula key and power input shaft 1 are inserted
Close connection.The bearing 2 of power input shaft 1 is housed in mission case 11, and with grease in 10 seal box of oil sealing.Driving disc spacing pressing 9
Periphery is formed with the low roller rack 16 (as shown in Figure 3) of several middle high sides.In the opposite path of the one end projection one of driving disc spacing pressing 9
For spring position 19, it is the circular carrier of support spring 13.The outer diameter of driving disc spacing pressing 9 is set with mid-game 7, it is with the major diameter of driving disc spacing pressing 9
15 be fulcrum, and the two is slidably matched.
As the mid-game 7 of clutch, as shown in Figure 1, Figure 2, Figure 6 shows, which is evenly distributed with several rollings on the shell like tubular
Column bearing bore 14, the hole penetrate through Pan Bi.Roller rack 16 of the orientation locating for roller bearing bore 14 with design in 9 periphery of driving disc spacing pressing has
Nearly corresponding relationship, but for the hole is with respect to the roller rack 16 on driving disc spacing pressing 9, each roller bearing bore 14 does not simultaneously reside at rolling
On the central point of column track 16, but arranged in dislocation under the action of 13 elastic force of support spring.Between driving disc spacing pressing 9 and mid-game 7
The formation of 13 its elastic force of support spring is because the both ends of the spring are respectively using above-mentioned two disk as fulcrum.
As shown in Figure 2, Figure 3, Figure 4, above-mentioned 9 mid-game 7 of driving disc spacing pressing needs arranged in dislocation, concrete mode and effect are as follows: support
13 one end of spring is fulcrum according to the spring base 19 of driving disc spacing pressing 9, and mid-game 7 is pushed into A point 17, A by the other end (along Fig. 3 up time direction)
Point 17 is for the internal diameter of driven disc 6, and roller 8 is in the narrow herring bone between two disks, therefore roller 8 is able to driving disc spacing pressing 9
With 6 wedging of driven disc and transmit power.This direction of transfer is exactly engine rotation and the direction that vehicle advances.It can be seen that
The combination of clutch has just been predefined in the position of vehicle advance by the original design of this bidirectional automatic clutch, and this is default
Position do not need engine braking and reversing (electric car) when, be that normality is constant.
As shown in figure 4, another main part driven disc 6 of this clutch, its internal diameter is in round mouth peviform, with contain driving disc spacing pressing 9, in
Disk 7, roller 8.The outer diameter of driven disc 6 is regular circle shapes, and core necking is that internal key and power output shaft 12 insert.Driven disc 6
Effect is that it also undertakes the power that driving disc spacing pressing 9 and roller 8 transmit being forwarded to power output other than accommodating above-mentioned all
Axis 12.
The roller 8 that boundary is mounted in mid-game 7 between clutch driving plate 9 and driven disc 6 is Liang Panjian intermediary power
Clutch part, the roller rack 16 that lateral edge driving disc spacing pressing 9 provides in motion profile are run, middle part by mid-game 7 common action of controlling,
The inner wall clutch of outer end and driven disc 6.It can according to the needs of the running different operating conditions of vehicle, in time power combined or
Separation.
The control assembly of this bidirectional automatic clutch, including magnetization semi-disc 3, as shown in figure 5, electromagnetic switch 4 and switch
Push rod 5.Be that can reach the purpose for automatically controlling automatic clutch following two operating condition using said modules: one is vehicle rows
It sails when gug needs engine braking, realizes the reversed combination of clutch.Its mode is the electricity for acquiring brake system and providing
Subsignal (such as car light route), to instruct electromagnetic switch 4 and switch plunger 5 to act.The magnetization being mounted on switch plunger 5
For semi-disc 3 close to the side of mid-game 7 under the promotion of electromagnetic switch 4 and switch plunger 5, mid-game 7 is the magnetic in magnetization semi-disc 3
It is obstructed and of short duration stagnant stops under the effect of drawing.Mid-game at this time can overcome the elastic force of spring 13 to make the fortune to lag relative to driving disc spacing pressing 9
It is dynamic, and B point 18 (as shown in Figure 3) is moved to from track A point 17 together with mounted in roller 8 thereon.Again because of 6 revolving speed of driven disc at this time
Higher than driving disc spacing pressing 9, therefore driven disc 6 is reversely by 8 wedge pressure of roller on the B point 18 of driving disc spacing pressing 9, by the dynamic of engine and transmission system
Power transmitting reversely links up.Rule are handed over to require " gug must not slide " to reach.Second situation is how to realize power train
Unite power reverse drive to meet the requirement of reversing, (electric car especially moved backward by motor reversion) power at this time
Reversed combine of reverse drive and above-mentioned transfer principle, i.e. clutch is identical.When only electromagnetic switch 4 acts
Command signal source is not identical, and the electronic signal at this moment needing to acquire is backing system (such as reversing light switch interlock circuit
Signal), to command the reversed combination of this clutch in due course.
