In addition, these gear shift arms 248 and the utilization of gear shift arm driveshaft 249 are supported in the gear shift Returnning spring 250 of shift shaft 230 and are positioned at neutral position.Specifically, gear shift Returnning spring 250 makes helical spring two end part extend to form straight line shape respectively, and these 2 two end part then will be fixed on the neutral locating stud 251 of the non-icon framework of power transmitting deice 200, the warpage sheet 249a of gear shift arm driveshaft 249 and be formed in the warpage sheet 248c double team setting in the through hole 248b of gear shift arm 248.Mode by this, gear shift Returnning spring 250 can when the gear train of the formation gear of speed change gear 240 carries out conversion action, makes to reverse and get back to original neutral position towards the gear shift arm 248 of diagram clockwise direction or counterclockwise rotation and gear shift arm driveshaft 249 towards the counterclockwise direction of icon or up time meter direction to clutch 210 be changed into top gear.In addition, in the diagram, the sense of rotation of the clutch lowering or hoisting gear bar 222 of the gear of speed change gear 240 when gear down action, gear shift arm 248, gear shift arm driveshaft 249 and gear shift drum 245 represents with dotted line arrow respectively.
At this, the relation first with regard to clutch driving play L1, gear-change operation play L2 and gear-change operation play L3 is illustrated.In this example, clutch drives play L1, gear-change operation play L2 and gear-change operation play L3 is set as the relation forming L1 < (L2+L3).Therefore, after the rotary actuation that the power transmitting deice 200 of this example is configured to mat shift shaft 230 first makes clutch 210 start action, speed change gear 240 just starts the mode of action.
ECU300 (EngineControlUnit, engine control unit) be made up of the micro computer formed with CPU, ROM, RAM, and according to remember in advance ROM etc. non-icon control program integration control the molar behavior of vehicle power transmission system 100.Specifically, ECU300 according to from carry establish the handle 301 of the vehicle of this vehicle power transmission system 100 to arrange Gear-shift switch 302 output gearshift control signal, control each action of spark plug 112, sparger 118, unloaded regulating valve 122 and shift shaft drive motor 231, perform the gear up of speed change gear 240 and each gear shifting operation of gear down.
In addition, this ECU300 not only controls vehicle power transmission system 100, but establishes the action of the vehicle of this vehicle power transmission system 100 to carry out integration control with regard to carrying.Therefore, the each portion of engine 110 that ECU300 is comprising engine 110 and power transmitting deice 200 possesses non-icon sensor, the necessary message of action control in order to obtain engine 110 (amount of oxygen such as, in the aperture of the aperture of the revolution of engine 110, the speed of a motor vehicle, air throttle 117, unloaded regulating valve 122, outlet pipe, the angle of rotation of shift shaft 230, shift pattern and clutch lifting amount etc.).According to the message obtained from these sensors, each control object comprising engine 110 is controlled.In addition, in FIG, the path of the message obtained from these sensors utilizes dotted line arrow to represent.And the rotary actuation by shift shaft drive motor 231 makes the part of power transmitting deice 200 action also represent with dotted line arrow.
(action of vehicle power transmission system 100)
Then, the action of the vehicle power transmission system 100 just formed in the above described manner is illustrated.This vehicle power transmission system 100 is configured at the cushion of automotive bicycle or the below of fuel tank as earlier mentioned, utilizes vehicle operators (not shown) action to the gear-change operation of Gear-shift switch 302.The operation of gear up that this operator carries out and gear down operate gear up action and the gear down action of the vehicle power transmission system 100 produced, and are mutually the same beyond the sense of rotation of shift shaft 230 and the action that produces because of this sense of rotation.Therefore, in following action specification, the gear down action only with regard to speed change gear 240 is illustrated, but gear up action also symbolic animal of the birth year with.
Specifically, in vehicle is with the arbitrary gear walking in 2 grades ~ 4 grades (also referred to as " 2 speed ~ 4 speed ") (with reference to Fig. 4), gear is declined 1 grade and be transformed into the bottom gear of 1 grade ~ 3 grades (also referred to as " 1 speed ~ 3 speed ") time, vehicle operators can operate the Gear-shift switch 302 being located at handle 301, and indicates gear down to ECU300.Hereby one side is with reference to the sequential chart shown in Fig. 5, and one side illustrates that vehicle power transmission system 100 operates the gear down course of action carried out for this gear down.
When operator carries out gear down operation to Gear-shift switch 302, namely Gear-shift switch 302 exports gear down control signal (the opportunity T of the gearshift control signal representing gear down to ECU300
1).When the gear down control signal input that Gear-shift switch 302 exports, ECU300 can will make unloaded regulating valve 122 output to the actuator 124 of unloaded regulating valve 122 toward the unloaded regulating valve control signal needed for opening side action immediately.By this, namely shunt access 121 is located at circulation status by actuator 124 makes valve body 123 be shifted by unloaded regulating valve 122.
When operator carries out gear-change operation to this Gear-shift switch 302, usually, because the acceleration operation of operator can be removed in advance, so air throttle 117 is in and is closed lock status.And, be in the state to the unloaded degree of what is called that the air quantity of its supply can not make engine 110 stop in the cylinder 111 of engine 110.Then, by opening unloaded regulating valve 122, the air of required air delivery volume when exceeding zero load in the cylinder 111 of engine 110, will be supplied to.By this, engine 110, just from the low rotation status that the closedown because of air throttle 117 is formed, while the rotary driving force transmit mode of aftermentioned clutch 210 is removed, makes revolution slowly rise.
Then, ECU300 can export to make shift shaft 230 towards the rotation driver signal of sense of rotation rotary actuation corresponding to the gear gear down action with speed change gear 240 to gear shift shaft drive motor 231.After responding this instruction, the sense of rotation that shift shaft drive motor 231 just starts towards the gear down action with speed change gear 240 is corresponding carries out rotary actuation, makes shift shaft 230 rotary actuation.Action by this, when shift shaft 230 carries out rotary actuation, namely the clutch lowering or hoisting gear bar 222 and the gear shift arm driveshaft 249 that are fixed on this shift shaft 230 carry out rotary actuation (the dotted line arrow with reference in Fig. 4) respectively.
In this case, clutch lowering or hoisting gear bar 222 and can just have clutch between dynamic clutch lowering or hoisting gear 221 and drive play L1, have gear-change operation play L2 between gear shift arm driveshaft 249 and gear shift arm 248, the hook 248a and bulging the pin between 246a of gear shift that are linked to gear shift arm 248 have gear-change operation play L3.And these clutches drive between play L1, gear-change operation play L2 and gear-change operation play L3, have the relation of L1 < (L2+L3).Therefore, vehicle power transmission system 100 is after the rotary actuation of shift shaft 230, after the inefficacy stroke of clutch driving play L1 filled up by clutch lowering or hoisting gear bar 222, first, the friction plate 211 of clutch 210 separates with clutch plate 212, that is the lifting amount of clutch 210 starts to increase (opportunity T
2).
On the other hand, speed change gear 240 through the inefficacy stroke of gear shift arm driveshaft 249 blocking gear-change operation play L2 and the inefficacy stroke of hook 248a blocking gear-change operation play L3 being linked to gear shift arm 248 after this gear-change operation play L2 is by the inefficacy stroke of blocking, and can start action.More specifically, speed change gear 240 meeting is after 2 continuous print inefficacy strokes of blocking gear-change operation play L2, L3, that is the lifting amount of clutch 210 starts the (T increased
2) after, gear shift drum pin 246a mat hook 248a starts to be pulled, and makes the gear up action of gear start to carry out (opportunity T
3).
The gear down action of the gear of this speed change gear 240, by by mainshaft gear 241a to each other and counter shaft gear 242a gear down nipper wheels connecting state to each other " the gear disengaging step " removed and to be formed and " the gear connecting step " of gear down backgear group connecting state that connecting state before this gear down is different formed.These 2 steps rotate between a tooth amount at scale plate 246b to carry out.
Speed change gear 240 after the gear down action of gear starts, utilizes the rotary actuation causing gear shift drum 245 via the rotary actuation of gear shift drum pin 246a and scale plate 246b, makes reverse shift fork 244 sliding transfer, carry out gear and depart from step.In this case, gear depart from step by make mutually chimeric mainshaft gear 241a to each other and counter shaft gear 242a sincere sub-243a to each other deviate from from embedding hole 243b and carry out.
Secondly, when this gear departs from step execution, owing to making the deceleration torque in speed change gear 240 (torque produced due to so-called engine brake) reduce because opening unloaded regulating valve 122, simultaneously, because of the beginning gear up of clutch 210, the rotary driving force being delivered to speed change gear 240 from engine 110 can reduce, so gear departs from step and becomes easy execution.By this, speed change gear 240 can before clutch 210 becomes and the rotary driving force from engine 110 can not be delivered to the degree of speed change gear 240 side substantially, arrive state that friction plate 211 leaves with clutch plate 212 (that is, clutch off state) (opportunity T
5) before, gear will be made to depart from step and to complete (opportunity T
4).That is the driving force transmit mode that the gear train of gear before formation speed change is formed can be removed by speed change gear 240.In addition, while the driving force transmit mode of this speed change gear 240 is removed, the shaft torque of countershaft 242 can fall mistake.
Then, the continuous rotation by gear shift drum 245 drives, and speed change gear 240 after the disengaging step of then gear, can perform the connecting step of gear.In this case, gear connecting step by by the mainshaft gear 241a forming gear after gear down to each other and counter shaft gear 242a sincere sub-243a to each other insert embedding hole 243b and perform.And, when performing this gear connecting step, clutch 210 is in so-called clutch off state, simultaneously, mat is opened deceleration torque in speed change gear 240 that unloaded regulating valve 122 causes and is reduced, and makes the gear connecting step of the gear train of formation gear be able to smoothness and carries out.By this, namely the gear down action of speed change gear 240 gear completes (opportunity T
6).In addition, in this example, as shown in Figure 5, gear connecting step completed before the lifting amount of clutch 210 reaches maximum flow, but the opportunity that completes of gear connecting step, reached opportunity of maximum flow with the lifting amount of clutch 210, and which formerly all has no relations.
Then, after the gear gear down action of speed change gear 240 completes, ECU300 just exports to gear shift shaft drive motor 231 control signal that instruction replys respectively.Specifically, ECU300 can export to gear shift shaft drive motor 231 rotation driver signal that drive motor 231 is driven towards the direction contrary with during gear down action, and this driving is for identical with the rotating amount of the rotary actuation in order to gear down.By this, shift shaft 230 can be returned to the position before gear down action in the position of sense of rotation, meanwhile, is fixed on the clutch lowering or hoisting gear bar 222 of this shift shaft 230 and gear shift arm driveshaft 249 and also can be returned to position before gear down action.
As a result, clutch 210 reduces gradually by lifting amount, and friction plate 211 continues touch with clutch plate 212, and the state that the rotary driving force starting engine 110 is passed, that is, start clutch and cut moving of state and change (opportunity T
7).Because this clutch 210 moves in the process of changing towards clutch incision state, the state that engine 110 is connected gradually with driving wheel of vehicle can be formed, so the revolution of engine 110 also increases gradually.
Then, touch completely with clutch plate 212 at the friction plate 211 of clutch 210, and the time point that engine 110 is connected with driving wheel of vehicle, ECU300 can by order to make unloaded regulating valve 122 output to actuator 124 (the opportunity T of unloaded regulating valve 122 toward the unloaded regulating valve control signal of closing side action
8).By this, unloaded regulating valve 122 can make the aperture of shunt access 121 reduce by actuator 124 makes valve body 123 be shifted, and makes the air delivery volume flowed in cylinder 111 from shunt access 121 reduce.By this, because the minimizing state of the deceleration torque (because of the torque that so-called engine brake causes) in the speed change gear 240 that formed toward the air that cylinder 111 supplies via shunt access 121 and unloaded regulating valve 122 is removed, a succession of gear down action of vehicle power transmission system 100 just completes.In addition, in this case, the amount that ECU300 makes unloaded regulating valve 122 close, the amount making unloaded regulating valve 122 open when operating with this gear down is corresponding, and the amount that the air delivery volume needed for engine 110 zero load is guaranteed.
Also can understand from above-mentioned action specification, if according to above-mentioned example, before the main shaft 241 of vehicle power transmission system 100 when speed change gear 240 being carried out gear down action and the driving force transmission between countershaft 242 start, vehicle power transmission system 100 utilizes the unloaded regulating valve 122 of engine 110 that the gettering quantity of countercylinder 111 is increased.By this, speed change gear 240 is when gear down action, utilize the action of unloaded regulating valve 122, the deceleration torque (torque that so-called engine brake produces) in speed change gear 240 can reduce, and the shift step forming the gear train of gear becomes easily carries out.That is, vehicle power transmission system 100 involved in the present invention, when gear up or the gear down iso-variable velocity action of speed change gear 240, no matter the driving force transmit mode of clutch 210, the conversion action of the gear train of the formation gear of speed change gear 240 all can start.Result, compared to clutch 210 driving force transmission disconnect after, the inchoate traditional power transfer unit of gear shifting operation of speed change gear 240, the gear shifting operation of speed change gear 240 can complete rapidly, meanwhile, the uncomfortable feeling brought to operator because so-called torque drop loses gently can be subtracted when this gear shifting operation.
Moreover, when implementing of the present invention, be not limited to above-mentioned example, as long as not departing from the scope of the object of the invention, various change can be done.
Such as, in above-mentioned example, shift shaft 230 is formed to utilize the mode of shift shaft drive motor 231 rotary actuation.But shift shaft 230 also can utilize the trick of vehicle operators to carry out manually-operable and do mechanical type rotating driving.Now, ECU300 can control the action of unloaded regulating valve 122 in the same manner as above-mentioned example by the angle of swing of detection shift shaft 230.
Moreover, in the vehicle power transmission system 100 of above-mentioned example, be configured to, before mat speed change gear 240 carries out gear down action, first open unloaded regulating valve 122, start the mode of the gear up of clutch 210 simultaneously.But, as long as vehicle power transmission system 100 is configured to before mat speed change gear 240 carries out gear down action, first open the mode of unloaded regulating valve 122, be then not limited to above-mentioned example.Thus, also can be configured to such as, after the action that mat speed change gear 240 carries out gear down starts, just start the mode of the gear up of clutch 210.
That is in above-mentioned example, clutch drives the amount of play L1 to be set as few compared with the total amount of gear-change operation play L2, L3.By this, can utilize the rotary actuation of shift shaft 230, after first making clutch 210 action, speed change gear 240 just starts action.But, as long as vehicle power transmission system 100 is configured to the mode first opening unloaded regulating valve 122 before speed change gear 240 carries out gear down action as previously mentioned, so, the action that mat speed change gear 240 carries out gear down can be set as and start the rear formation just starting the gear up of clutch 210.In this case, clutch drives the amount of play L1 to be set greater than the total amount of gear-change operation play L2, L3.In addition, gear-change operation play L2, L3 not necessarily must be made up of 2 play, also can be made up of gear-change operation play L2 or gear-change operation play L3, also can be made up of more than 3 play.In addition, clutch drives play L1 also can be made up of more than 2 play.
In addition, in the vehicle power transmission system 100 of above-mentioned example, before the driving force being configured to clutch 210 has disconnected, the mode that the driving force between the main shaft 241 of speed change gear 240 and countershaft 242 disconnects first has been completed.By this, the traditional power transfer unit of the gear shifting operation of speed change gear 240 is just started after the driving force transmission of clutch 210 disconnects, the gear shifting operation of speed change gear 240 can more promptly complete, meanwhile, the uncomfortable feeling bringing operator during this gear shifting operation because so-called torque drop loses can alleviate.But, after the driving force that vehicle power transmission system 100 can be configured to clutch 210 has disconnected, just completed the mode that the driving force between the main shaft 241 of speed change gear 240 and countershaft 242 disconnects, should belong to certain.
Moreover in the vehicle power transmission system 100 of above-mentioned example, before the driving force of clutch 210 has disconnected, the unloaded regulating valve 122 of mat has made the gettering quantity of cylinder 111 increase.Therefore, before the driving force of clutch 210 has disconnected, that is, in the state that clutch 210 connects completely or not exclusively, the conversion action of the gear train of the formation gear of speed change gear 240 can start, compared to traditional power transmitting deice, the gear shifting operation of speed change gear can complete rapidly.But vehicle power transmission system 100 also can be configured to after the driving force of clutch 210 has disconnected, the mode that the unloaded regulating valve 122 of mat makes the gettering quantity of countercylinder 111 increase.If mode according to this, then after at least forming speed change, the gear connecting step of gear can carry out glibly.
Again, in the vehicle power transmission system 100 of above-mentioned example, after being configured to the driving force transmission reply of clutch 210, the mode that the gettering quantity of countercylinder 111 reduces by the unloaded regulating valve 122 of mat.By this, after the formation speed change of speed change gear 240 gear gear connecting step after, friction plate when the driving force transmission of clutch 210 starts again 211 can reduce with the revolution difference of clutch plate 212, and the connection of clutch 210 can smooth and easyly be carried out.But, the air that unloaded regulating valve 122 countercylinder 111 of mat provides, that is, the state that the deceleration torque in speed change gear 240 that unloaded regulating valve 122 formed reduces opened by mat, can be undertaken by least 1 step that the gear of speed change gear 240 departs from the Connection Step of step, gear connecting step and clutch 210.By this, each step can be carried out glibly.Thus the gettering quantity of the countercylinder 111 that the unloaded regulating valve 122 of mat provides reduces, (opportunity T when the state that can be configured to such as be transmitted substantially by the rotary driving force from engine 110 at clutch 210 is formed
7 ') mode of carrying out.
In addition, in the vehicle power transmission system 100 of above-mentioned example, shunt through air throttle 117 and supply air to the unloaded regulating valve 122 in the cylinder 111 of engine 110, mainly being formed with valve body 123 and actuator 124.That is unloaded regulating valve 122 is equivalent to unloaded gettering quantity regulating mechanism involved in the present invention.But, as long as this unloaded gettering quantity regulating mechanism is shunted through air throttle 117 and can adjust the formation of the air quantity be supplied in cylinder 111, be then not limited to above-mentioned example, other can be adopted to form, should belong to certain.
And, in the vehicle power transmission system 100 of above-mentioned example, after unloaded regulating valve 122 is opened, engine 110 revolution start to rise be set in speed change gear 240 formation speed change before the driving force transmit mode that formed of the gear train of gear remove after (opportunity T
4).But, after unloaded regulating valve 122 is opened, making engine 110 revolution start the opportunity of rising, freely can set by suitably setting the aperture of shunt access 121 internal diameter or unloaded regulating valve 122.Such as, can be set in the opportunity that the revolution of engine 110 starts to rise unloaded regulating valve 122 open after, the gear train of gear starts before gear departs from step before the gear up of clutch 210 or before the formation speed change of speed change gear 240.
