Embodiment
Below in conjunction with accompanying drawing, a kind of manual transmission of the embodiment of the present invention is described in detail.
Should be clear and definite, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Referring to Fig. 1 and the specific embodiment that Figure 2 shows that a kind of manual transmission of the present invention, described manual transmission comprises input from the input shaft 10 of the driving force of motor and the output shaft 20 be arranged in parallel with input shaft 10 and be set in input shaft 10 and the multiple gear train G1 on output shaft 20, G2, G3, G4, G5, G0, multiple gear train G1, G2, G3, G4, G5, G0 comprise the most high-grade gear train G 5 and the most high-grade beyond gear train G1, G2, G3, G4, G0, the most high-grade gear train G5 comprises the most high-grade actuation gear 51 and the most high-grade driven gear 52 that are connected with a joggle, wherein,
The most high-grade actuation gear 51 empty set also can by being fixed on input shaft 10 with the rigidly connected lazy-tongs 53 of input shaft 10 on input shaft 10, and the most high-grade driven gear 52 empty set also can realize with the combination of output shaft 20 by overrunning clutch 4 or be separated on output shaft 20.
The beneficial effect of the manual transmission that the embodiment of the present invention provides is, when being linked into the most high-grade, the most high-grade actuation gear 51 is by being fixed on input shaft 10 with the rigidly connected lazy-tongs 53 of input shaft 10, the most high-grade gear train G5 engages each other, the power of motor passes to the most high-grade driven gear 52 by the most high-grade actuation gear 51, and the most high-grade driven gear 52 is rotated by overrunning clutch 4 driver output axle 20, transmitting torque.When sliding, driver unclamps gas pedal, and engine speed reduces rapidly, input shaft 10 rotating speed is lower than output shaft 20 rotating speed, and now, the rotating speed of output shaft 20 surmounts the rotating speed of the most high-grade driven gear 52, make overrunning clutch 4 be in separated state, vehicle just automatic safe slides.When accelerating again after the speed of a motor vehicle reduces, as long as to put one's foot down, engine speed is improved, the most high-grade driven gear 52 rotating speed is again higher than the rotating speed of output shaft 20, overrunning clutch 4 locking also drives output shaft 20 to rotate together, so automobile recovers the most high-grade traveling again.
It should be noted that, for above-described embodiment, gear train G1, G2, G3, G4, G5 are forward gear group, G0 is for retreating shelves gear train, and the most high-grade gear train is G5, and the gear train beyond the most high-grade is G1, G2, G3, G4 and G0, and gear train G1, G2, G3, G4, G5 arrange successively along the direction that motor is contrary, namely arrange successively from high to low by velocity ratio, so the most high-grade gear train is positioned at the end of speed changer, and end uses lock-nut 7 to be fastenedly connected.But the present invention is not limited to 5 grades of manual transmissions, is also not limited to the most high-grade end being arranged on speed changer, and wherein the most high-grade gear train also can be arranged on the middle part of speed changer, particular location is arranged depending on the quantity of speed changer forward gears and speed changer space.
Shown in seeing figures.1.and.2, the most high-grade actuation gear 51 is supported on input shaft 10 by bearing 5, and the most high-grade driven gear 52 is supported on output shaft 20 by bearing 5.The most high-grade traditional gear train is generally comprise fast pulley and castor, fast pulley and its back shaft are rigidly connected, castor is idle running support freely on its back shaft, when needs carry out the most high-grade gear transmission, castor is by being fixed on back shaft with the rigidly connected lazy-tongs of its back shaft.But traditional Placement when the speed of a motor vehicle is higher unclamp gas pedal time, vehicle can reverse direction actuation engine revolution, does not reach the object of fuel-economizing like this when high speed slide.And the most high-grade gear train all by bearings on respective axle, be equivalent to the most high-grade intermeshing gear train and be castor, but the most high-grade described driven gear is supported on described output shaft by described overrunning clutch simultaneously, like this when being linked into the most high-grade, the most high-grade described actuation gear by with the rigidly connected mechanism supports of described input shaft on described input shaft, the most high-grade described gear train engages each other, rotating speed due to described input shaft is greater than the rotating speed of described output shaft, therefore described overrunning clutch is in lockup state, the most high-grade driven gear described in the power of motor is passed to by the most high-grade described actuation gear, the most high-grade described driven gear drives described output shaft to rotate by described overrunning clutch, transmitting torque.When sliding, driver unclamps gas pedal, engine speed reduces rapidly, described input shaft rotating speed is lower than output shaft rotating speed, now, described in the rotating speed of described output shaft surmounts, the rotating speed of the most high-grade driven gear, makes described overrunning clutch be in separated state, the most high-grade described driven gear freely rotates relative to described output shaft by bearing, can not pull motor.
Again referring to shown in Fig. 2, the end of the most high-grade driven gear 52 is provided with endoporus, and overrunning clutch 4 is set in described endoporus.The installation of described overrunning clutch is similar to the installation of bearing, also be by offering endoporus on the most high-grade driven gear, described overrunning clutch is sleeved in endoporus, play the supporting effect of bearing too, overrunning clutch is located at one end of the most high-grade driven gear by the present invention, the other end then uses bearings, can reduce the axial dimension of clutch like this, saves cost.
Further, the axial length of described overrunning clutch is less than or equal to the axial length of described endoporus.Described like this overrunning clutch can not protrude into outside described endoporus, can shorten the axial dimension of output shaft.
Secondly, described overrunning clutch can be roller one-way clutch, ratchet one-way clutch or voussoir overrunning clutch.The present invention illustrates the working principle of overrunning clutch for roller clutch, can find out as shown in Figure 3, roller one-way clutch 4 comprises outer ring 41, outer ring 41 is fixedly connected with the wheel hub of the most high-grade driven gear 52, and between outer ring 41 and output shaft 20, form the raceway with inclined-plane 44, be provided with roller 42 in described raceway, roller 42 separates with one end of spring 43 and contacts, and the other end of spring 43 is connected with outer ring 41.Its working principle is: when the most high-grade driven gear 52 turns clockwise, roller 42 is rolled to narrow end 45 under the influence of centrifugal force, now overrunning clutch 4 is lockup state, the power of motor passes to the most high-grade driven gear 52 through the most high-grade actuation gear 51, drives output shaft 20 to rotate clockwise together simultaneously; When unclamping gas pedal, engine speed declines rapidly, the rotating speed of the most high-grade driven gear 52 also declines rapidly, but because effect output shaft 20 rotating speed of inertia is constant, now the rotating speed of output shaft 20 is greater than the rotating speed of the most high-grade driven gear 52, roller 42 meeting Compress Spring 43 under the effect of frictional force is rolled to the position of wide end 46, and now overrunning clutch 4 is separated state, and output shaft 20 can not pull motor.
It should be noted that, also can arrange inner ring for above-mentioned roller-type one way clutch, form raceway between outer ring and inner ring, inner ring is fixedly connected with output shaft.The embodiment of the present invention does not arrange inner ring, can reduce the radial dimension of clutch to reduce bore aperture.The working principle of the clutch of other type and the working principle of above-mentioned roller-type one way clutch similar, the non-return device of such as unidirectional slide block can certainly be used, as long as the function of unidirectional locking can be realized.
Again, the castor that the gear train beyond the most high-grade described in each comprises empty set and the fast pulley engaged with described castor, the side of described castor is provided with lazy-tongs.As can be seen from Figure 1, in gear train G 3 and G4, driving wheel is castor, and follower is fast pulley, and in gear train G1, G2 and G0, driving wheel is fast pulley, and follower is castor.From transmission principle, have at least a gear (i.e. castor) can relatively rotate with its place back shaft in each gear train, and by linking with rigidly connected lazy-tongs on its place back shaft and back shaft, be generally simplified structure or operation, take to be fixedly mounted on its back shaft with castor meshed gears.Only with lazy-tongs, castor need be fixedly connected with the gear transmission that just can realize corresponding gear to its back shaft when being linked into corresponding gear like this.And if gear train is all set to castor, then need gear train to be all fixedly connected with corresponding back shaft when being linked into corresponding gear, complex structure, the clutch of automatic locking or separation also gear transmission or gear-change operation can be realized although use, but turn increase the clutch that cost is relatively high in the middle of invisible, be unfavorable for that the cost of speed changer reduces.
Therefore the present invention is only needing the most high-grade driven gear slided installs overrunning clutch, and the gear train of other gear still takes the set-up mode of fast pulley and castor.Certainly, if engine displacement is large or Transmission gear is many, also can in the driven gear of secondary high-grade gear train sheathed overrunning clutch, automobile can slide at secondary top grade, further reduces oil consumption; And generally do not allow also not need engage a gear to slide at lower gear, therefore also need not overrunning clutch be set.
Secondly, described manual transmission also comprises housing, is provided with bearing 6 in described housing, input shaft described in described bearings or described output shaft.
The embodiment of the present invention additionally provides a kind of automobile, the above-mentioned manual transmission comprising motor and be connected with described motor.Its beneficial effect is: when described automobile is when being linked into the most high-grade, the most high-grade described actuation gear is by being fixed on described input shaft with the rigidly connected lazy-tongs of described input shaft, the most high-grade described gear train engages each other, the most high-grade driven gear described in the power of motor is passed to by the most high-grade described actuation gear, the most high-grade described driven gear drives by described overrunning clutch that described output shaft rotates, transmitting torque.When sliding, driver unclamps gas pedal, engine speed reduces rapidly, described input shaft rotating speed is lower than output shaft rotating speed, now, described in the rotating speed of described output shaft surmounts, the rotating speed of the most high-grade driven gear, makes described overrunning clutch be in separated state, vehicle just automatic safe slides, and reduces fuel consume.When accelerating again after the speed of a motor vehicle reduces, as long as to put one's foot down, engine speed is improved, the most high-grade described driven gear rotating speed is again higher than the rotating speed of described output shaft, described overrunning clutch locking also drives described output shaft to rotate together, so automobile recovers the most high-grade traveling again.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
