Embodiment
Referring to accompanying drawing, automatic type manual transmission according to the present invention and selector gear thereof are described.According to automatic type manual transmission of the present invention also with manual transmission (for example, typical conventional manual speed changer shown in Figure 1A and 1B) change and form for basis, there is the gear type variable transmission mechanism identical with manual transmission, but the selector gear of manual transmission has been done to modification.
Particularly, Fig. 2 A, 2B and 3 show an embodiment according to automatic type manual transmission of the present invention and selector gear thereof.Here still as an example of five speed transmissions with five forward gears 1-5 and a reverse gear R example, this embodiment is described.As shown in Fig. 2 B and 3, comprise three reverse shift fork assemblies 41,42,43 according to this embodiment's selector gear 14, rotary drum 21, and three shift levers 31,32,33.
Reverse shift fork assembly 41-43 has and known configurations the same in manual transmission, comprises reverse shift fork and dimple and sliding selector shaft optional, between these two.In this embodiment, as shown in Figure 3,42 of reverse shift fork assemblies have reverse shift fork and dimple, and reverse shift fork assembly 41 and 43 also comprises additional sliding selector shaft, each reverse shift fork assembly can be engaged by engaging sleeve separately with the gear pair that is located at diverse location in variable transmission mechanism 13.In order to realize this joint, each reverse shift fork assembly can move back and forth (the edge direction parallel with output shaft 16 with input shaft 15 in Fig. 3).For example, reverse shift fork assembly 41 can move back and forth, to drive its engaging sleeve 51 optionally to engage with gear pair 61 or 62, make machine power via engaged gear pair transmission, thereby speed changer just obtains the velocity ratio of being determined by this gear pair.Should point out, the working method of reverse shift fork assembly and gear type variable transmission mechanism is well known in the art, only makes above brief description here.
Rotary drum (also can be described as " cam ") 21 is configured to be driven and rotates around the parallel longitudinal axis 22 of the direction moving back and forth with reverse shift fork assembly.Can adopt electronic, hydraulic pressure or pneumatic system to drive rotary drum 21 to rotate.Certainly, also can control as required rotary drum 21 stops having turned over after special angle.(rotary drum 21 is formed with endless around its outer circumferential face, end-to-end is in the form of a ring) groove 23, groove 23 comprise when in the time that the unfolded drawing of the outer circumferential face of rotary drum 21 is looked, be vertical with longitudinal axis 22 rectilinear lineal shape portion section 25 and with the section 24(of S shape portion of this lineal shape portion section continued access S-shaped described unfolded drawing (waveform) for example, referring to Fig. 4 B in the unfolded drawing of downside)." the S shape " of indication is interpreted as the continuously smooth curve shape being made up of two that protrude the in the opposite direction parts that are connected in the present invention.
Shift lever 31-33 is connected between rotary drum 21 and reverse shift fork assembly 41-43.Each shift lever 31-33 has first end and the second end.Wherein, first end (only showing the first end 81 of shift lever 31 in Fig. 3) contacts with the side of groove 23 and engages with described side slip, thus first end along with rotary drum 21 rotate and groove 23 is interior can be along following the track being limited by groove 23 when mobile.The second end of each shift lever is bonded on all the time in the dimple of corresponding reverse shift fork assembly and is connected (for example, as shown in Figure 3, it is interior that the second end 91 of shift lever 31 is bonded on the dimple of reverse shift fork assembly 41 all the time) with this reverse shift fork assembly operation.Shift lever 31-33 can be parallel in the direction moving back and forth with reverse shift fork assembly 41-43 plane in for example, around shaft swing separately (,, in Fig. 3, shift lever 31 can 71 swing around the shaft).
According to the above-mentioned configuration of the above-mentioned annexation of rotary drum, shift lever and reverse shift fork assembly and rotary drum groove, along with rotary drum 21 rotates, the first end that is slidably engaged on the shift lever in the groove 23 of rotary drum moves along the track of groove 23.In the time of lineal shape portion section 25 slip joint except S shape portion section 24 of first end and groove 23, (first end is not subjected to displacement in the direction of the longitudinal axis 22 of rotary drum 21, look from Fig. 3, do not move left and right), shift lever remains on middle stand up position thus; And in the time of first end and S shape portion section 24 slip joint, first end follows by two that protrude the in the opposite direction S shape paths that roughly curved portion forms and moves left and right, so shift lever correspondingly swings around its rotating shaft, the second end of shift lever is also moved left and right, and then drive the reverse shift fork assembly that operation connects with it to move back and forth optionally to engage specific gear pair and the particular gears that realizes speed changer.In the present invention, the bending/tortuous degree of S shape portion section 24 should so design, and makes in the time that rotary drum 21 rotates, and the first end of shift lever can smoothly slide through whole S shape portion section 24.
In the present embodiment, the first end of three shift lever 31-33 in groove 23 install position and S shape portion section 24 rotary drum week length be upwards designed to, make along with rotary drum 21 rotates, the first end of three shift lever 31-33 successively individually with S shape portion section 24 slip joint, make thus three shift levers swing back and forth successively and drive successively three reverse shift fork assembly 41-43 to move back and forth once by corresponding the second end.Preferably, as shown in Figure 4 B, the first end of three shift lever 31-33 is equally spaced distributed in groove 23 with 120 °, and S shape portion section 24 rotary drum week length be upwards set to 1/3rd of the circumferential total length of rotary drum 21 or groove 23.Move back and forth in process once at each reverse shift fork assembly, this reverse shift fork assembly to multipotency successively engages once with two gear pairs, thereby can sequentially realize at the most two and can transmit mechanokinetic gear.Like this, in the situation that rotary drum 21 rotates a circle and in turn makes three reverse shift fork assembly 31-33 respectively move back and forth once, speed changer can sequentially be realized at the most six can transmit mechanokinetic gear.Fig. 5 A to 5F shows and utilizes the gearshift figure that realizes five forward gearss and a reverse gear according to the selector gear of the present embodiment.As shown in Fig. 5 A to 5F, along with rotary drum 21 rotates, shift lever 33,32 and 31 drives respectively corresponding reverse shift fork assembly successively to move back and forth once (movement direction that the arrow in each figure represents corresponding reverse shift fork assembly), thereby only need control the rotation angle of rotary drum 21, just for example can realize successively reverse gear R and forward gears 1-5.Because groove 23 is endless, rotate circle arbitrarily so can control rotary drum 21 uniaxiallies, in rotating, every circle can sequentially realize above-mentioned six gears.Should point out, rotary drum 21 also can be driven into and rotate backward, and the order that realizes like this each gear is also contrary.
As mentioned above, only need utilize an actuator (electronic, hydraulic pressure or pneumatic) to drive rotary drum 21 to rotate each gear that just can sequentially realize speed changer according to selector gear of the present invention and automatic type manual transmission, with the automatic type manual transmission simplified in comparison of two actuators of employing of the prior art structure, improved reliability.In addition, owing to can sequentially obtaining each gear, while noting be used in each gear shift, all control respectively the dual operation (having exempted " gear selecting " operation) that two actuators carry out " gear selecting " and " shift ", so can save shift time, accelerate switching speed.
At the first end of three shift levers during all not with S shape portion section 24 slip joint or only with the non-protruding middle part of S shape portion section 24 or two engaged at end, the shift lever stand up position that mediates, corresponding reverse shift fork assembly does not engage with any gear pair, thereby speed changer is not in transmitting mechanokinetic neutral position.Here,, from according to the above-mentioned working method of selector gear of the present invention, can transmit between any two the adjacent gears in mechanokinetic gear and all have a neutral position at each that sequentially realize.
In the above-described embodiments, selector gear according to the present invention is provided with three groups of shift levers and reverse shift fork assembly, but, the invention is not restricted to this, but can carry out according to the gear number of the required realization of speed changer the quantity of free setting shift lever and reverse shift fork assembly.For example, two groups (seeing Fig. 4 A), four groups (seeing Fig. 4 C) or more groups of shift levers and reverse shift fork assembly also can be set, can realize respectively thus four at the most, eight or morely can transmit mechanokinetic gear.Even can imagine one group of shift lever and reverse shift fork assembly are only set, the now entirety of groove 23 S-shaped (only including S shape portion section 24), correspondingly, speed changer can be realized two can transmit mechanokinetic gear.Namely, be that n(n is equal to or greater than 1 integer in the quantity of shift lever and reverse shift fork assembly), 2n can be sequentially realized at the most and mechanokinetic gear can be transmitted.Correspondingly, the first end of n shift lever is preferably arranged to be equally spaced distributed in the groove 23 of rotary drum 21 (n is more than or equal to 2 situation), and the S shape portion section 24 of groove 23 is at the 1/n of the rotary drum week circumferential total length that is rotary drum of length upwards.But, the present invention is also not limited to this, for make the first end of n shift lever in the time that rotary drum rotates can be successively individually with S shape portion section 24 slip joint, as long as n first end in groove install position and S shape portion section rotary drum week length be upwards designed such that the circumferential lengths of S shape portion section is less than or equal to the circumferential distance between any two adjacent first ends.
Below with reference to Fig. 6, some design parameters according to selector gear of the present invention are described.Show respectively the annexation figure between rotary drum 21, shift lever and reverse shift fork assembly in the left, center, right of Fig. 6 portion, the unfolded drawing of groove 23, and the side view of shift lever.As shown in Figure 6, the diameter of rotary drum 21 is labeled as D, the unidirectional range that reverse shift fork assembly moves back and forth is labeled as L, the maximum protrusion height of S shape portion section 24 (, the ultimate range that the single curved portion of S shape portion section 24 protrudes from the lineal shape portion section of groove 23) be labeled as m, the quantity of shift lever is counted n, and the distance that the first and second ends of shift lever swing rotating shaft to it in the swinging plane of shift lever is labeled as respectively S1 and S2.Therefore, the circumferential total length of groove 23 is that Pi × D(is corresponding to 360 °), and as mentioned above, the circumferential lengths of S shape portion section 24 be preferably Pi × D/n(corresponding to 360 °/n).In addition, in the time that the first end of shift lever arrives the summit of curved portion of S shape portion section, the second end of shift lever drives reverse shift fork assembly to reach its unidirectional range, so there is following relation: m/L=S1/S2.Can design according to above parameters relationship according to all parts in selector gear of the present invention.
In the above-described embodiments, groove 23 has and comprises two roughly S shape portion sections 24 of curved portion, thus in the first end of shift lever and the process of S shape portion section slip joint, corresponding reverse shift fork assembly moves back and forth once to multipotency and successively engages with two gear pairs that are located at reverse shift fork both sides and sequentially realize two gears; But, those skilled in the art easily expect, also S shape portion section can be revised as to the C shape portion section that only includes a curved portion, now in the first end of shift lever and the process of C shape portion section slip joint, corresponding reverse shift fork assembly moves back and forth and once can only engage with a gear pair that is located at reverse shift fork one side and realize a gear, like this first end of n shift lever successively individually when C shape portion section engages speed changer can sequentially realize that n is individual altogether can transmit mechanokinetic gear.
In the present invention, from Fig. 2 B, rotary drum 21 is arranged on the outside of case of transmission 12, and each shift lever extends through case of transmission 12.Like this, in the time constructing according to automatic type manual transmission of the present invention, as shown in Figure 2 A, only the shell block 17(that surrounds hand-gear shift lever bottom in conventional manual speed changer need be shown in to Figure 1A) replace to a shell block 18 of sealing rotary drum 21, and change without the housing of manual transmission being carried out to other, therefore manufacture easy according to automatic type manual transmission according to the present invention and cost is low.
