Detailed description of the invention
The present invention is described in detail below in conjunction with specific embodiment.It should be noted that, the skill described in following embodiment
The combination of art feature or technical characteristic is not construed as isolating, and they can be mutually combined thus reach more preferable
Technique effect.
As shown in Figure 1-2, the present invention provide a kind of Retarder include housing 1, rotor 2, stator 3, output shaft 4,
Cylindrical spring 5；Stator 3 is fixed in housing 1, and stator 3 is connected with rotor 2, and rotor 2 and stator 3 enclose formation working chamber
6, rotor 2 is connected with output shaft 4 engagement, and cylindrical spring 5 is enclosed within the outside of output shaft 4, and one end of cylindrical spring 5 withstands on rotor 2
On, one end of cylindrical spring 5 withstands on housing 1.
It is provided with internal helical gear on rotor 2, output shaft 4 is provided with the outer oblique gear 41 first coordinated with internal helical gear, turn
Internal helical gear on son 2 is provided with 11 helical tooths, the internal helical gear on rotor 2 on the outer oblique gear 41 on output shaft 4
It is 35 ° or 39.326 ° with helical angle A of the helical tooth on the outer oblique gear 41 on output shaft 4.
When retarder works, being full of Medium Oil in working chamber 6, output shaft 4 rotor driven 2 rotates, the medium in cavity
Oil stops rotor 2 to rotate thus forms the counteracting force to rotor 2, and the counteracting force of formation overcomes the resistance of cylindrical spring 5 to make
Rotor 2 is close to stator 3, and when rotor 2 is near stator 3, stator 3 produces counteracting force by Medium Oil to rotor 2, now turns
The counteracting force that son 2 is subject to increases, and the counteracting force that rotor 2 is subject to is the biggest the easiest to be close to stator 3, the closer to stator 3
Counteracting force is the biggest, counteracting force the biggest just the closer to stator 3 thus define in daily life described leveraging competitor's strength to hit back and follow
The rule that sequence is progressive, until rotor 2 rotor 2 when stator 3 distance reaches 2mm-2.5mm stops mobile, wherein, rotor 2 from
The time interval beginning to move into stopping movement is the 1-2 second, and it is anti-by the maximum of Medium Oil that rotor 2 now has obtained stator 3
Active force is so that vehicle deceleration, here it is the attracting process of stator 3 rotor 2.
In the above-mentioned rotor attracting process with stator, Retarder by making rotor along output to the change of helical angle
Axle outer oblique gear moves distance to stator and reduces, and the time arriving stator reduces, the most therewith so that whole retarder is opened
The time reaching optimum efficiency shortens, and beneficially traffic safety adds safety coefficient, decreases the generation of accident, alleviate row
Car is braked, and reduces energy resource consumption.
Present invention also offers a kind of Retarder rotor stator separating method, comprise the steps:
When retarder does not works, the Medium Oil in the working chamber 6 that rotor 2 and stator 3 are formed returns trapped fuel room, in working chamber 6
The counteracting force that rotor 2 is produced by remaining air, air in working chamber 6 and stator 3 is less than elastic force when cylindrical spring 5 compresses
Thus rotor 2 is pushed open, when cylindrical spring 5 rotor 2 pushed open and stop moving apart from rotor 2 during for 16mm-16.5mm with stator 3
Dynamic, wherein, rotor 2 is the 1-2 second from beginning to move into the time interval stopping movement.Now the gas in working chamber 6 will not produce
The raw counteracting force to rotor 2, car energy loss in the process of moving is the most minimum, here it is the separating of stator rotor
Journey.
By to the helical angle of the helical tooth on the outer oblique gear 41 on the internal helical gear on rotor 2 and output shaft 4 more
Changing and make rotor 2 move distance reduction along output shaft 4 outer oblique gear 41 to stator 3, the time arriving stator 3 reduces one second the most therewith
By two seconds, making whole retarder open and reach than originally faster one second to two seconds optimum efficiency time, traffic accident often just occurs to exist
Between one second, so within one second in advance, making retarder reach optimum efficiency be conducive to traffic safety, increase safety coefficient, minimizing accident
Generation, alleviate service brake, reduce and far seek cost, from the foregoing, reduce rotor 2 when helical angle can make retarder start and arrive
The time reaching stator 3 can shorten, and when retarder quits work, rotor 2 leaves time of stator 3 and also can also can shorten on the contrary, because of
Changing lesser trochanter 2 for spiral and leave the distance reduction of stator 3, rotor 2 leaves the time shortening needed for stator 3, thus shortens air
Time to the counteracting force that rotor 2 produces, decrease rotor 2 and automobile is produced unnecessary energy expenditure, it is achieved that be energy-conservation
Reduce discharging.
Although having been presented for some embodiments of the present invention herein, it will be appreciated by those of skill in the art that
Without departing from the spirit of the invention, the embodiments herein can be changed.Above-described embodiment is exemplary, no
Should be using the embodiments herein as the restriction of interest field of the present invention.
