Summary of the invention
Therefore, the object of this invention is to provide the gearshift assembly of the manual transmission for Motor Vehicle, described gearshift assembly provides axially Support Gear and then can realize speed changer structure compact especially with minimum structure space demand.
According to the present invention, described object is realized by the gearshift assembly of the manual transmission for Motor Vehicle, described gearshift assembly has gear shift unit, and described gear shift unit can rotate around variator axis and can axially movably and be substantially placed on transmission shaft to anti-rotating; With multiple space maintaining member circumferentially distributed, described space maintaining member extends through the portion of leaving a blank in gear shift unit and has the axial end portion be inverted mutually, and wherein at least one axial end portion of each space maintaining member stretches out axially beyond gear shift unit and is configured for the axial support of the axially adjacent gear of manual transmission.It is this that to extend axially through space maintaining member that gear shift unit extends be in manual transmission axially Support Gear simple, compact and low-cost possibility.
In a mode of execution of gearshift assembly, at least one space maintaining member is directly axially fixed on transmission shaft.By this way, not only the axial force of gear is via space maintaining member transmission, to be imported in transmission shaft by another bearing components, and axial force directly imports in transmission shaft via each space maintaining member.This causes the unloading of other bearing components, and described bearing components can correspondingly be formed thus more compactly.
Especially, at least one space maintaining member has radial projection, described projection extend radially inwardly in the state of having assembled of manual transmission and form fit join in the radial recess be associated of transmission shaft.Such radial projection such as can be axially fixed on transmission shaft by being expended to be shaped and then can to realize space maintaining member with minimum manufacture by space maintaining member remodeling especially simply.
In addition, at least one space maintaining member can have radial recess on the side being adjacent to gear shift unit, and described recess axially extends at the drive range of gear shift unit in the region of the axial end portion of gear shift unit.Recess at space maintaining member relative to the radial outside of variator axis being conducive to the gearshift resistance little especially when shifting out the gear switched.

According at least one mode of execution of gearshift assembly, space maintaining member in axial direction extends and has the cross section of rectangle, wherein especially observes along the circumference of variator axis the size that the size of the space maintaining member radial direction be greater than along variator axis observes space maintaining member.As an alternative, space maintaining member other, especially round cross section also can imagine certainly.
Space maintaining member can have the outstanding protuberance of radially outward on axial end portion, the backstop of the gear that the axis that the formation of described axial end portion formation is used for manual transmission adjoins.The protuberance given prominence to by this radially outward especially squarely obtains stop surface for the increase of gear or abutment face with minimum material consumption.The stop surface of described increase or abutment face cause less surface pressure when transmitting axial force and then cause the less stress of space maintaining member in the contact areas and gear.
According to another mode of execution of gearshift assembly, be provided with the arresting disc of at least one annular, described arresting disc is supported on space maintaining member and along the second contrary axial direction around transmission shaft and along the first axial direction and is supported on adjacent gear in the state of having assembled of manual transmission.The arresting disc of such annular is additional or the possibility of alternative, is correspondingly reduced in the surface of contact increased between space maintaining member and axially adjacent gear the surface pressure occurred when transmitting axial force.
In the described mode of execution of gearshift assembly, space maintaining member preferably has axial protuberance, and described axial protuberance axially extends in the recess of arresting disc, makes the arresting disc of annular be configured for the radial bearing of space maintaining member when assembly of shifting gears rotates.At this, in the recess of space maintaining member in the portion of leaving a blank of gear shift unit than at arresting disc, there is larger radial gap.Therefore, the centrifugal force occurred when assembly of shifting gears rotates of space maintaining member is absorbed by arresting disc, makes the friction between gear shift unit and space maintaining member be minimum when axial relative movement and does not affect or only insignificantly affect gear shifting force to be applied.
Preferably, gear shift unit forms circlewise and around transmission shaft in the state of having assembled of manual transmission, is wherein formed in the radially inward edge of gear shift unit for the portion of leaving a blank of space maintaining member, makes space maintaining member directly be adjacent to transmission shaft.Space maintaining member can be realized especially simply by the described structure of assembly of shifting gears to be axially fixed on transmission shaft and then advantageously axial derivation power.
If gear shift unit is formed and around transmission shaft in the state of having assembled of manual transmission, so the inward flange in the portion of leaving a blank and gear shift unit that are used for space maintaining member can be separated circlewise.This can realize the better axial force transmission between gear and space maintaining member, because space maintaining member is arranged on gear-needle bearing now radially outward and then be in axial direction adjacent to gear all sidedly.
In addition, the present invention also comprises the manual transmission of Motor Vehicle, and described manual transmission has: transmission shaft, and described transmission shaft has outer toothed portion; Gearshift assembly mentioned above, described gearshift assembly is included in gear shift unit that transmission shaft can move axially, annular; And at least one gear, described gear shaft is adjacent to gearshift assembly and can is bearing on transmission shaft rotationally to ground, wherein gear shift unit has interior teeth portion, and described interior teeth portion joins in the described outer toothed portion of transmission shaft.

Fig. 2 to 5 illustrates a mode of execution of the manual transmission 10 for Motor Vehicle, and it has: transmission shaft 14, and described transmission shaft has outer toothed portion 24; Gearshift assembly 26, described gearshift assembly is included in gear shift unit 12 that transmission shaft 14 can move axially, annular; And two gears 16, described gear is axially adjacent to gearshift assembly 26 respectively and can be such as bearing on transmission shaft 14 via needle bearing 28 rotationally.On the contrary, gear shift unit 12 has interior teeth portion 30, and described interior teeth portion joins in the described outer toothed portion 24 of transmission shaft 14 and gear shift unit 12 is connected with transmission shaft 14 to anti-rotating substantially.Interior and outer toothed portion 30 or 24 is omitted in figs 2 and 3 in order to improve general view.
Gear shift unit 12 axial shifting power loads, so that such as by (unshowned) selector fork operation manual transmission 10 of manual transmission 10.
Except already mentioned, can around variator axis A rotate and can move axially and be substantially placed in anti-rotating except the gear shift unit 12 on transmission shaft 14, gearshift assembly 26 for the manual transmission 10 of Motor Vehicle also comprises multiple space maintaining member 32 circumferentially distributed, and described space maintaining member extends through the portion of leaving a blank 34 in gear shift unit 12 and has the axial end portion 36,38 be inverted mutually.
Generally speaking, at least one axial end portion 36,38 stretches out axially beyond gear shift unit 12 and the axial support of gear 16 that adjoins of the axis being configured for manual transmission 10.According in the embodiment of Fig. 2 and 3, two ends 36,38 of even each space maintaining member 32 are stretched out axially beyond the end be associated with end 36,38 of gear shift unit 12 and are formed direct axial stop respectively and then be configured for the cod of the gear 16 that two axis adjoin.
Gear shift unit 12 is formed and circlewise around transmission shaft 14 in the state of having assembled of manual transmission 10, portion of leaving a blank 34 wherein for space maintaining member 32 is formed on the radially inward edge 40 of gear shift unit 12, makes space maintaining member 32 directly be adjacent to transmission shaft 14.
According to Fig. 5, space maintaining member 32 not only joins in the portion of leaving a blank 34 of gear shift unit 12 but also joins in the outer toothed portion 24 of transmission shaft 14, wherein space maintaining member 32 be placed in outer toothed portion 24 adjacent tooth between and especially also cling on the described adjacent tooth of outer toothed portion 24.By this way, space maintaining member 32 additionally can assist the teeth portion 24,30 be engaged with each other between transmission shaft 14 and gear shift unit 12 during transmitting torque.
Preferably, space maintaining member 32 forms substantially pin-shapedly and in axial direction extends.Although space maintaining member 32, according to having circular cross section in the embodiment of Fig. 2 to 5, certainly also can use the space maintaining member 32 of the cross section (see Figure 10 to 13) of the cross section, the especially rectangle that are applicable to other in the enforcement flexible program of the alternative of gearshift assembly 26.
Space maintaining member 32 is such as steel pin, and described steel pin and its shape of cross section are independently contained in the portion of leaving a blank 34 of gear shift unit 12 axially slidably.
According to Fig. 2, space maintaining member 32 is particularly by form fit, be axially fixed on transmission shaft 14.For this reason, generally pin-shaped space maintaining member 32 is provided with radial projection 42, described radial projection extend radially inwardly in the state of having assembled of manual transmission 10 and form fit join in the radial recess 44 be associated of transmission shaft 14.By this way, the axial force of gear 16 directly can be imported in transmission shaft 14 by space maintaining member 32.
Self-evidently, according to the space maintaining member 32 of Fig. 2 and 3 only at gear 16 axially along the axial support being configured for two adjacent gears 16 when moving towards gearshift assembly 26 direction.Also for ease of limiting gear 16 axially away from gearshift assembly 26 motion, another axial support is required.Another supporting element described such as can, other assembly 26 adjacent via the axis with the gear mesh (as illustrated in figs 2 and 3) be associated realize or in a conventional manner via additional bearing components as the realization such as arresting disc, bail wire.
Fig. 6 to 8 illustrate according to another mode of execution, for the gearshift assembly 26 of the manual transmission 10 of Motor Vehicle, but this mode of execution is different from the mode of execution according to Fig. 2 to 5 by means of only at least one additional arresting disc.
Gearshift assembly 26 in Fig. 6 to 8 additionally comprises two annular arresting discs 22, and described arresting disc is supported on space maintaining member 32 and along the second contrary axial direction along the first axial direction is respectively supported on adjacent gear 16 around transmission shaft 14 in the state of having assembled of manual transmission.Although described arresting disc 22 improves the number of components of gearshift assembly 26 in an undesired manner on the one hand and requires additional structure space, also bring following technological merit on the other hand.
Therefore, such as, increase the surface of contact with adjacent gear 16 by arresting disc 22, this causes the less surface pressure on gear 16 when transmitting axial force.
According to Fig. 6 to 8 it is also clear that, space maintaining member 32 has axial protuberance 46 on its end 36,38, described axial protuberance axially extends in the recess 48 of arresting disc 22, makes the arresting disc 22 of annular be configured for the radial bearing of space maintaining member 32 when assembly 26 of shifting gears rotates.
The axial protuberance 46 of space maintaining member 32 radially extends within the inward flange 50 of arresting disc 22, and arresting disc 22 is placed on protuberance 46.Because the radial gap in the portion of leaving a blank 34 of gear shift unit 12 is greater than the radial clearance in arresting disc 22, so absorbed by arresting disc 22 every the radial centrifugal force of holder 32 at gearshift assembly 26 rotational time, make the friction between gear shift unit 12 and space maintaining member 32 be extremely little when axial relative movement and do not affect or only insignificantly affect the axial shifting power of needs.
In the mode of execution without arresting disc 22, on the contrary, because the friction of the raising between gear shift unit 12 and space maintaining member 32 can cause certain raising of the axial shifting power of needs.
Fig. 8 illustrates the three-dimensional detailed drawing of the space maintaining member 32 of the gearshift assembly 26 according to Fig. 6 and 7.At this, space maintaining member is configured to steel pin, and wherein radial projection 42 is axially shaped at space maintaining member 32 center by the plastic remodeling of steel pin.
In addition, the axial end portion 36,38 of space maintaining member 32 can be known and see axial protuberance 46, described axial protuberance extends in the recess 44 of arresting disc 22 in the state of having assembled of gearshift assembly 26.Via space maintaining member 32 end face 52 be posted by its, the arresting disc 22 that is connected in-between, the axial force of adjacent gear 16 correspondingly imports in space maintaining member 32.The end face 54 of axial protuberance 46 is contrary preferably to be separated with adjacent gear 16, and total axial force is imported in space maintaining member 32 via arresting disc 22.
In addition, the axial protuberance 46 of the space maintaining member 32 according to Fig. 8 forms the supporting surface 56 that radially outward points to, and via described supporting surface, space maintaining member 32 is radially supported on arresting disc 22.
Fig. 9 illustrate according to another mode of execution, for the gearshift assembly 26 of the manual transmission 10 of Motor Vehicle, but described mode of execution is different from the mode of execution according to Fig. 2 to 5 by means of only the radial recess 58 of space maintaining member 32.
According to Fig. 9, space maintaining member 32 has radial recess 58 about variator axis A on the side being adjacent to gear shift unit 12, that is on radial outside, and described radial recess axially extends at the drive range shown in Figure 9, that move axially of gear shift unit 12 in the region of the axial end portion 62 of gear shift unit 12.
Tolerance of size due to centrifugal force and routine can cause the inclination of space maintaining member 32 in the described drive range moved axially, as its in fig .9 by a dotted line 60 (in order to graphical illustration large) indicate.By this way, the axial end portion 62 of gear shift unit 12 can produce clamping, described clamping causes the gear shifting force F required when extracting gear of raising.By the radial recess 58 of the space maintaining member 32 in the region of the axial end portion 62 of gear shift unit 12, the friction of clamping when shifting out gear or raising can being reduced, making to ignore the impact on the gear shifting force required when extracting gear.
Figure 10 to 13 illustrates the manual transmission 10 of the Motor Vehicle of the gearshift assembly 26 had according to another mode of execution, but described mode of execution is different from the mode of execution of Fig. 2 to 5 by means of only the space maintaining member 32 changed.
In addition, the structure of the example of gear shift unit 12 is described according to the three-dimensional exploded view of the gearshift assembly 26 of Figure 10, described structure but as broad as long with the structure of gear shift unit 12 in other implementations.
In the case, gear shift unit 12 by the transmission dish 64 of annular and two coaxially directed, be axially arranged on the mesh plate 66 that transmission coils 64 both sides and assemble.In transmission dish 64, be provided with the otch 68 of four radial directed, in described otch, radially guide the pressure piece 70 having gear shift unit 12 respectively.In the topology example illustrated, transmission dish 64 and mesh plate 66 are fixed to one another as screw or rivet by bindiny mechanism 72, make the preassembled gear shift unit 12 of energy obtaining gearshift assembly 26 generally.
But about the axially support of gear 16, the special way of the described mode of execution of gearshift assembly 26 is space maintaining member 32, described space maintaining member has the cross section of rectangle in the current situation, wherein observes along the circumference of variator axis A the size that the size of space maintaining member 32 radial direction be greater than along variator axis A observes space maintaining member 32.
According to Figure 11, the outer toothed portion 24 of transmission shaft 14 is matched with its rectangular cross section in the region of space maintaining member 32.
In addition, can know identify according to Figure 11 and 13, space maintaining member 32 is arranged with the angle of 90 ° distribution circumferentially equably, especially.
In said embodiment, the projection 42 of the axial centre of space maintaining member 32 also can be molded on pin-shaped space maintaining member 32 by simple remodeling.
In addition, according to the space maintaining member 32 of Figure 10 to 13, there is substantially on axial end portion 36,38 protuberance 74 that radially outward is outstanding squarely, the backstop of the gear 16 that the axis that described axial end portion is configured for manual transmission 10 adjoins.
As projection 42, protuberance 74 is preferably also molded on space maintaining member 32 by simple remodeling technique.
The protuberance 74 given prominence to by radially outward can with the surface of contact of certain scope free adjustment between space maintaining member 32 and adjacent gear 16.Preferably, at this, selecting abutment face so greatly, making to set acceptable surface pressure and for not needing arresting disc 22 in increasing further surface of contact.
Figure 14 illustrates the manual transmission 10 of the Motor Vehicle of the gearshift assembly 26 had according to another mode of execution, but described mode of execution is different from the mode of execution according to Fig. 2 to 5 by means of only the location of space maintaining member 32 in gear shift unit 12.
According to Figure 14, gear shift unit 12 is formed circlewise and around transmission shaft 14 in the state of having assembled at manual transmission 10, the portion of leaving a blank 34 wherein for space maintaining member 32 differently separates with the inward flange 40 of gear shift unit 12 with aforementioned embodiments.Thus, the space maintaining member 32 of gearshift assembly 26 also radially separates with transmission shaft 14 and is not correspondingly fixed in the axial direction on transmission shaft 14.Thus, the axial force of gear 16 is not directly imported in transmission shaft 14 by space maintaining member 32, but on the adjacent gear being only delivered to manual transmission 10 or on other axially support element or bearing components.
The advantage of described mode of execution is, space maintaining member 32 is also radially arranged on outside (needle roller) bearing 28 by radially separating with transmission shaft 14, and correspondingly axially end 36,38 clings on gear 16 all sidedly, this causes the surface pressure of reduction when transmitting axial force.
