Background technique
In the mechanical type automotive transmission, need utilize gear-selecting-shifting mechanism to realize its gear selecting and gear shift function, change to required gear in the position of basic fixed and will make the driver control operating handle, that then need consider speed changer selects the gear shift positioning device.General selecting, changing shifts of automobile speed changer mechanism is to utilize the face of the plane set on the manipulator housing or gear shift shifting block to realize that gear selecting is spacing, does not then have spacing or guiding device in the gear selecting direction during gear shift.Therefore, traditional speed changer driver's inconvenience positional operand vertical pole when gear selecting; During gear shift, operating handle rocks more greatly in the existence of gear selecting direction, and the gear location is inaccurate, has influenced the gear shift feel greatly.In a word, conventional speed changer selects gear shift to put in place and feels not obvious because shortage is selected the gear shift positioning device preferably, and property of automatic shft is low, can't satisfy the more and more higher requirements of quality such as modern day user is flexible to gear shift, gear is clear.
Find Chinese patent title: a kind of gear shift positioning device of automobile mechanical transmission, the patent No.: 200420004806.X through literature search to prior art.Specific descriptions are: the utility model relates to a kind of gear shift positioning device of car gear shifting Effector, particularly automobile mechanical transmission.Technological scheme covers 1 by handling, plain cushion 2, ball ring 3, spacer 4, shift level 5, spring 6, spring seat 7, dust-proof cover 8 are formed, manipulation is covered 1 and is fixed on the back body case of automobile gearbox, shift level 5 one ends are handlebar, the other end is connected with the gear shift shifting block of gearbox by spacer, plain cushion 2, ball ring 3, spring 6, spring seat 7, dust-proof cover 8 are enclosed within on the operating handle 5 successively, coupling connects mutually, and said spring is a volute spring 6.Owing to adopt volute spring to substitute existing cylindrical spring, cancellation gland, snap ring, the volute spring elasticity coefficient and the natural frequency of vibration are variate, help eliminating or relaxing resonance, eliminate the purpose that car load vibrates different sound, simplify the structure simultaneously thereby reach, not only eliminate or slowed down noise, and be convenient to assembly and disassembly, assembly technology is simple, and is easy to maintenance.This patent belongs to traditional direct-type selector device, mainly simplifies the structure, and mechanism guarantees its position selecting aspect the gear shift location not accurately, therefore still fails to realize selecting the accurate location of gear shift.
The model utility content
The utility model is at the prior art above shortcomings, position mechanism is handed in the gear shift that provides a kind of king's of having font to select the gear shift groove, realize selecting accurately the gear shift location, have the gear shift that improves shifting block and hand over position mechanism, solved the existing gear shift defective of selecting of general speed changer effectively, made and select the gear shift accurate positioning, gear is clear, greatly improve property of automatic shft, alleviated driver's driving intensity.
The utility model is achieved through the following technical solutions, the utility model comprises: guide finger, king's font gear-changing and selecting shifting block, abutment sleeve and shift selection shaft, wherein: king's font gear-changing and selecting shifting block contacts with abutment sleeve and guide finger respectively, guide finger and shift selection shaft are parallel to each other, and shift selection shaft is fixedlyed connected with king's font gear-changing and selecting shifting block.
Described king's font gear-changing and selecting shifting block comprises: shifting block body and king's font are selected the gear shift groove, and wherein: king's font selects the gear shift groove to be positioned at shifting block body top.
Described king's font selects the width of gear shift groove and the external diameter of guide finger to be complementary.
The side of described shifting block body is provided with M font groove.
The contacted side of described abutment sleeve and king's font gear-changing and selecting shifting block is provided with steel ball.
Described king's font selects the slot pitch of gear shift groove to equate with the gear selecting stroke of king's font gear-changing and selecting shifting block end.
It is little Spielpassung that described king's font is selected the groove width of gear shift groove and the targeting part of guide finger.
It is 55 ° that described king's font selects even number shelves in the gear shift groove to rise the guiding groove angle that the even number shelves fall in odd number shelves or odd number shelves.
The utility model carries out work in the following manner: when the even number shelves rose odd number shelves or odd number shelves and fall the even number shelves, two relative big chamferings of same row formed a passage, under the mating reaction of guide finger, play the effect of guiding, location to selecting gear shift.When between two gears of the same row of " king " font groove, switching mutually, under the mating reaction of guide finger, also to selecting gear shift to play guiding, positioning action.
The utility model quite flexibly and can make a manipulator and cover little assembly together with other part of gear-selecting-shifting mechanism, is convenient to assembling and buying when the even number shelves rise odd number shelves or odd number shelves and fall the even number shelves, reduced manufacture cost significantly.

Embodiment
Below embodiment of the present utility model is elaborated; present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed mode of execution and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, present embodiment comprises: guide finger 1, king's font gear-changing and selecting shifting block 2, abutment sleeve 3 and shift selection shaft 4, wherein: king's font gear-changing and selecting shifting block 2 contacts with abutment sleeve 3 and guide finger 1 respectively, guide finger 1 and shift selection shaft 4 are parallel to each other, and shift selection shaft 4 and king's font gear-changing and selecting shifting block 2 are fixedly connected sequentially.
Described king's font gear-changing and selecting shifting block 2 comprises: shifting block body 5 and king's font are selected gear shift groove 6, and wherein: king's font selects gear shift groove 6 to be positioned at shifting block body 5 tops.
Described king's font selects the width of gear shift groove 6 and the external diameter of guide finger 1 to be complementary.
