Two, automatic over-drive gear transmission: connect two or more combinations thereof formula free wheel devicees on input shaft side by side, the overcoat of the clutch of least significant end links to each other with output shaft; Other is provided with a jack shaft, which is provided with one group of gear and the corresponding one by one engagement of gear on the above-mentioned clutch, by select each to the velocity ratio of gear to reach the speed of the different gears of output.Other is provided with a clutch control device, each control gear is made up of coil, electromagnet, pusher dog, the electrical connection of control gear is by unified intergrated circuit control, circular groove in the slip ring in pusher dog in each control gear and the corresponding clutch cooperates, stirring slip ring on request moves guide rod, plectrum moves with the position of control roller on wedge shape space thereupon, overcoat is engaged with star-wheel or takes off and closes.
Owing to adopted technique scheme, do not need the synchronizer (synchronizing process) in the general vehicle speed changer during this shifting of transmission, can be under the situation of not cutting off power, moment of stepping on the throttle can be finished gearshift procedure, carry out with the motor acceleration synchronization, and the utility model control system and gearshift mechanism simple (having only parameter of the speed of a motor vehicle, no hydraulic mechanism), short, speed changer friction of shift time and impact greatly alleviate compared with the prior art.
In order to describe the utility model in further detail, following routine accompanying drawing provides most preferred embodiment of the present utility model.
Description of drawings:
Fig. 1 is the plan view of composite type overrunning clutch;
Fig. 2 is the A-A sectional view of Fig. 1, and upper half part of figure is that slip ring mediates, and guide rod diameter major part and plectrum state of contact, lower half portion of figure are that slip ring is shifted to the left side, thin part of guide rod and plectrum state of contact;
Fig. 3 is the sectional view of automatic over-drive gear transmission.
Embodiment:
The plan view of composite type overrunning clutch is shown in Fig. 1 figure, 2, single free wheel device with the left side in Fig. 1 is an example, overcoat (6) lateral part is provided with the gear coaxial with overcoat (5), star-wheel (3) is provided with one group of pivot pin (4), and its distribution is illustrated in figure 2 as 24 (its quantity can be provided with as required); The two ends of each pivot pin (4) hinged plectrums (8) are respectively formed a plectrum and are paid, and the hinged roller of the other end that each plectrum is paid (7), roller are positioned on the wedge shape space of ratchet inclined-plane and overcoat formation on the star-wheel (as shown in Figure 2).The single free wheel device structure of right one side of something is identical with left side one side of something, use ring washer (2) axial restraint to form composite type overrunning clutch during assembling, and a slip ring (11) is set in the space between them, slip ring is provided with circular groove (10), the bi-side of slip ring are respectively equipped with the guide rod (9) of one group of symmetry, each guide rod all is slidingly matched with each self-corresponding guide hole, the setting of guide hole is paid corresponding (quantity and position) with plectrum, the diameter of guide rod is that outer imperial palace is little, and keeps in touch with interior plectrum (8) that each plectrum is paid.The working condition of combinations thereof formula free wheel device is as follows: input shaft 1 is connected drive two star-wheels and rotates synchronously with the star-wheel key, position shown in Figure 1 is that slip ring mediates, the plectrum contact that the both sides guide rod is outside and corresponding, shown in Fig. 2 first half, guide rod cross section larger part contacts with plectrum, makes roller remain on wedge shape space broad place, and roller and overcoat and star-wheel contact pressure are very little, star-wheel forward or reverse no matter, overcoat does not change (star-wheel idle running).When slip ring is beaten to the left, guide rod thin part in left side contact with plectrum that (the right was appointed for the thicker part branch and contacted with plectrum this moment, the right overcoat does not change), shown in lower half portion of Fig. 2, plectrum contacts with the thin part of guide rod, roller is shifted to the narrower place of wedge shape space makes overcoat engage rotation synchronously with star-wheel, then dallies during counter-rotating.In like manner, when slip ring was beaten to the right, then left side clockwise and anticlockwise all was idle running, and overcoat rotated synchronously when the right star-wheel was just changeing, and counter-rotating is idle running then.
The automatic over-drive gear transmission that is made of combinations thereof formula free wheel device as shown in Figure 3, connect four composite type overrunning clutch A, B, C, D (at least two of its quantity with key side by side on the input shaft Z1, can be provided with 3,4,5 or more as required), left end (starting point) ring washer (304) axial restraint, the overcoat of right-hand member (end) is connected with output shaft Z2.Other is provided with four clutch control devices and (only draws one among the figure, all the other omissions), each control gear is made up of electromagnetic coil (301), armature (302), pusher dog (303), the pusher dog of each control gear respectively with corresponding clutch in the circular groove of slip ring cooperate, to stir the slip ring move left and right.The electrical control of each control gear is then by unified electric control equipment control.One jack shaft Z3 is set, be provided with on it one group of gear respectively with corresponding clutch on gear be meshed, by selecting different velocity ratios to reach the output speed of different gears, as the gear among the clutch A (307,309) is reverse gear, intermediate gear, gear among the clutch B (310,311) is one grade of gear, pressure intermediate gear, gear among the clutch C (312,313) is fourth gear, six shift of gears, and the gear among the clutch D (314,315) is three-range transmission, direct high gear.Corresponding gear on the jack shaft Z3 is followed successively by (323,322,321,320,319,318,317,316), and gear (324) is the reverse gear idle gear.It is the same wherein forcing the advance velocity ratio of intermediate gear of intermediate gear and front, and structure is the same but the clutch direction is opposite, hangs up this two gears when simultaneously, makes it be in jointing state simultaneously, can have second gear engine braking function.The working condition of this speed changer is as follows, when pusher dog (303) moves left, slip ring moves left, star-wheel engages with overcoat (306), reverse gear (307) and countershaft-gear (323) engagement, then power passes to output shaft Z2 by jack shaft Z3, gear (316), (315), and wherein label (305,304) is respectively needle bearing and ring washer.The same A of the working condition of other clutch can analogize.
