The speed changer of present embodiment is equipped on the vehicle of front-wheel drive.And as shown in Figure 1, speed changer has transmission case 10, input shaft (the first axle) 11, the countershaft (the second axle) 12 be arranged in parallel with input shaft 11, change gear mechanism 20, gear 30 and receives the transmission case 40 of above-mentioned parts.Input shaft 11 and countershaft 12 are to be formed towards the mode in vehicle-width direction of the vehicle carrying this speed changer.
This speed changer has the shift gear that advance five keeps off, slow astern keeps off.Figure 1 illustrates the form of the transmission case of a speed changer removing part.In other words, the transmission case 40 shown in Fig. 1 is part of the whole (internal combustion engine side).In addition, in Fig. 1, accompanying drawing left is equivalent to front when being equipped on vehicle.Therefore, in FIG, when vehicle advances, input shaft 11 rotates in the counterclockwise direction, and countershaft 12 is rotated in a clockwise direction, and gear ring 24 rotates in the counterclockwise direction.When vehicle rollback, input shaft 11 rotates in the counterclockwise direction, idle gear 23 is rotated in a clockwise direction, countershaft 12 rotates in the counterclockwise direction, gear ring 24 is rotated in a clockwise direction.
Rotation from internal-combustion engine (omitting diagram) exports and can input to input shaft 11 discontinuously via clutch (omitting diagram).Countershaft 12 is provided with actuation gear (omitting diagram).Actuation gear is engaged in gear ring 24.Gear ring 24 is connected to driving wheel (omitting diagram).
Change gear mechanism 20 has the multipair speed change gear that carries out transmission of power between input shaft 11 and countershaft 12 to, one group of backward gear system and switch clutch mechanism (omit and illustrate).Speed change gear is to having the input shaft side gear 21 being arranged at input shaft 11 and the countershaft side gear 22 being arranged at countershaft 12.
Backward gear cording has the input shaft side gear 21 being arranged at input shaft 11, the countershaft side gear 22 and the idle gear 23 that are arranged at countershaft 12.Idle gear 23 is rotatable and can be disposed in idle gear supporting axle 13 movably vertically.Idle gear 23 can move by moving vertically between the position (becoming the position of fallback state) of both sides being engaged in input shaft side gear 21 and countershaft side gear 22 and the position not at least being engaged in a side.Idle gear 23 is formed with circular groove 231 in the periphery of a part for axis.
The plane that idle gear 23 and idle gear supporting axle 13 are formed to link input shaft 11 and countershaft 12 is for baseline configuration is in top.
The gear (fixed gear) forming the side in the right gear of speed change gear is fixed on the side in input shaft 11 and countershaft 12 along sense of rotation, be disposed in the opposing party in input shaft 11 and countershaft 12 gear (idle gear) idle running of the opposing party.
Switch clutch mechanism is the parts that can carry out between the state and fixing state of idle running relative to the axle 11 or 12 self being equipped with idle gear switching.Specifically, switch clutch mechanism arranges as carrying out relative to the axle 11 or 12 self being equipped with idle gear rotating (being formed with the spline that can slide axially), and be arranged between the vicinity of an idle gear (corresponding with fifth gear) or two idle gears (respectively and corresponding between first gear and second gear, between third gear and fourth gear), and spline is incorporated into the mechanism of this idle gear by sliding towards adjacent idle gear.
Gear 30 be to whether via multiple speed change gear to or backward gear system power is passed to from input shaft 11 mechanism that countershaft 12 selects.With with selected speed change gear to or retreat corresponding gear ratio power be passed to countershaft 12 from input shaft 11.
Gear 30 has block selecting shifting shaft 31, three fork shafts 32 ~ 34 and reverse arm 35.Block selecting shifting shaft 31 engages axial with one of them in three fork shafts 32 ~ 34 according to the regioselectivity of its sense of rotation.Block selecting shifting shaft 31 is provided with radially outstanding interior bar (omitting diagram), makes the change in location of interior bar to select the fork shaft 32 ~ 34 engaged by the rotation of block selecting shifting shaft 31.
The movement of the axis of block selecting shifting shaft 31 is driven in by the fork shaft 32 ~ 34 that block selecting shifting shaft 31 optionally engages.Fork shaft 32 ~ 34 be set to parallel with input shaft 11 and countershaft 12 and can the bar-shaped parts of movement vertically.Fork shaft 32 ~ 34 is fixed with selector fork (32a, 33a respectively.The component omission of linking with fork shaft 34 illustrates), make corresponding switch clutch mechanism driven by fork shaft 32 ~ 34 to moving of axis.Fork shaft 33 switches between fifth gear and retrogressing, and fork shaft 32 switches between fourth gear and third gear, and fork shaft 34 switches between first gear and second gear.
As shown in Figure 2, the end 351 of a side of reverse arm 35 swings for swing axis with trunnion 36.The end 352 of the opposing party is inserted in the circular groove 231 of idle gear 23.If oppositely arm 35 swings, then by its swing, idle gear 23 is moved vertically.In other words, if oppositely arm 35 swings, then idle gear 23 moves vertically.Reverse arm 35 is pressed by pin 331 by fork shaft 33 to the movement in A direction and swings.When (B direction: the direction selecting fifth gear) is mobile in opposite direction for fork shaft 33, pin 331 and reverse arm 35 onrelevant, reverse arm 35 does not swing.
The end 351 of reverse arm 35 utilizes trunnion 36 to be supported on the supporting mass (omitting diagram) of transmission case 40 by pivotable.Be provided with the part of supporting mass, hole 40c vertically penetrates the wall of transmission case 40.Return helical spring 37 and ball 38 is inserted with among the 40c of hole.By the power of return helical spring 37, the end 351 towards reverse arm 35 is biased ball 38.Two protuberance 351b and c forming the depression consistent with the profile of ball 38 are formed in end 351, thus swing limiting unit, this swing limiting unit embeds this depression by ball 38 and plays a role in the mode kept the position of reverse arm 35 or move to the position (position of the B of Fig. 2) that idle gear 23 does not engage when not applying power from fork shaft 33.The position of two protuberance 351b and c is formed through the movement of fork shaft 33 and the width of degree that cannot cross, and reverse arm 35 and idle gear 23 are biased along the direction of restoring to the position of not engaging.Reverse arm 35 can be directly fixed on the structure of transmission case 40 by adopting and realize by this structure.In other words, as the structure of reverse arm 35, adopt using one end as swing axis, utilize the other end to make idle gear 23 driven, at one end and between the other end, utilize block selecting shifting shaft 31, fork shaft 33 etc. to make it driven structure.
Here, due to the both sides of block selecting shifting shaft 31 and idle gear 23 with the plane linking input shaft 11 and countershaft 12 for benchmark is disposed in the same side (top), therefore the distance between block selecting shifting shaft 31 and idle gear 23 shortens, thus can shorten the reverse arm 35 of simplification.Such as can adopt as the simple structure by the machining sheets such as punch process etc.In existing speed changer, because idle gear etc. is arranged at the side contrary with gear, the transmission therefore for the power from block selecting shifting shaft 31 to idle gear needs to adopt complicated mechanism's (linkage mechanism etc.).On the other hand, because this reverse arm 35 makes the transmission of the power in close position abundant as much as possible, so can form simple form.
For retrogressing train of gearings, the gear being disposed in input shaft 11 due to the gear ratio being disposed in countershaft 12 is large, so the position of arranging idle gear 23 and idle gear supporting axle 13 is relatively near input shaft 11.Therefore, the position arranging three fork shafts 32 ~ 34 is set in the mode of not interfering with idle gear 23 grade close to countershaft 12.Therefore, preferably three switch clutch mechanisms are all arranged at countershaft 12.In this case, be only arranged at countershaft 12 owing to forming the key element (comprising synchronizer etc.) of switch clutch mechanism, therefore, it is possible to by one-body molded and manufacture input shaft 11 simply, thus can manufacture cost be reduced.
Here, when retreating, consider the stress putting on idle gear 23 and idle gear supporting axle 13.At existing configuration (idle gear supporting axle 13 be arranged in downside situation), the making a concerted effort of the power of torsional direction (power applied from input shaft 11 and countershaft 12 with joint efforts.Identical below) with the power of bending direction make a concerted effort become the direction almost mutually offsetted.On the contrary, in the configuration (idle gear supporting axle 13 is arranged in the situation of upside) of such as speed changer of the present invention, the power of torsional direction make a concerted effort with the power of bending direction make a concerted effort to become the direction almost mutually strengthened.Therefore, compared with existing configuration, in order to improve the intensity of idle gear 23, idle gear supporting axle 13, produce the needs increasing material, adopt the material of high strength.But, due to reduce movement from idle gear 23 to axis needed for parts (being reverse arm 35 and its incidental parts in speed changer of the present invention), therefore, it is possible to realize light and cost degradation as entirety.
As reverse arm 35, owing to can more simplify compared with existing mechanism, so the size of the transmission case 40 of receiving above-mentioned parts also can be reduced.In addition, owing to operating the mechanism of idle gear 23 without the need to being provided around input shaft 11 and countershaft 12, so as transmission case 40, can adopt close to and cover the form of input shaft 11 and countershaft 12, therefore can not as selecting the flowing hindering lubricant oil the existing mechanism of the retrogressing train of gearings of roundabout setting, thus supply lubricant oil to input shaft 11 and countershaft 12 and become easy.
Industry utilizes feasibility
Speed changer of the present invention finds following action effect by having above-mentioned structure.Namely, by the idle gear in retrogressing train of gearings and idle gear supporting axle being disposed in the upside (with the first axle and the second axle for benchmark) of speed changer, even if thus at the upside of speed changer configuration gear, for making the mechanism of idle gear movement also can not be complicated in gear.
In addition, can reduce speed changer as subsidiary effect, consequently, the casing of speed changer also can reduce and can form simple shape, thus can reduce casing sectional area, make internal surface round and smoothization.If cross section can be reduced, then, when splitting manufacture casing, the parts such as the bolt required for engaging of interface can be reduced.If can make internal surface round and smoothization, then the flowing of the lubricant oil in casing also can become smooth.
