Technical field
The utility model relates to a kind of saloon car transmission, relates to choosing, the gearshift mechanism of a kind of horizontal forerunner's car mechanical transmission in particular.
Background technique
Choosing, the gearshift mechanism of traditional car manual transmission, adopt a choosing, shift shaft mostly, choosing, gearshift mechanism are separately by choosing, the sealing of gear shift lid, this just causes many one sealing process in junction plane place, overall sealing performance to speed changer has certain influence, causes the whole cost of transmission assembly to increase simultaneously.
Summary of the invention
The purpose of this utility model is for the sealability of strengthening speed changer and overall performance, reduces its cost of production, overcomes deficiency of the prior art, and choosing, the gearshift mechanism of a kind of horizontal forerunner's mechanical saloon car transmission is provided.
The technical solution of the utility model is: be provided with choosing, gear shift guide block in the case of transmission, interlock board, choosing, shift shaft assembly, gear selecting mechanism assembly, the reverse gear locking is stirred pin, and its main feature is that choosing, shift shaft assembly, gear selecting mechanism assembly are connected on case of transmission and choosing, the gear shift guide block; The reverse gear locking is stirred pin and is linked to each other with choosing, shift shaft.
In order further to realize above purpose, described choosing, gear shift guide block are provided with the gear selecting bulb, gear selecting bulb draw-in groove; Described interlock board is provided with gear shift groove, gear selecting groove.
The utility model is than the advantage of prior art: this choosing, gearshift mechanism are one with gear selecting and gear shift, interlocking function collection, can effectively utilize gear selecting groove and gear shift groove to realize gear selecting and gear shift function, realize interlocking function simultaneously, can be not disorderly when guaranteeing choosing, gear shift grade and select two grades simultaneously.

Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Be provided with choosing, gear shift guide block 3 in the case of transmission 1, interlock board 4, choosing, shift shaft assembly 8 and gear selecting mechanism assembly 11, choosing, shift shaft assembly 8, gear selecting mechanism assembly 11 and case of transmission 1 link to each other with choosing, gear shift guide block 3 on its housing 1, and the reverse gear locking is stirred pin 10 and linked to each other with choosing, shift shaft 9.Choosing, shift shaft assembly 8 include choosing, gear shift guide block 3, interlock board 4, choosing, shift shaft 9 and gear shift groove 12; Gear selecting mechanism assembly 11 includes choosing, shift shaft 9, and the reverse gear locking is stirred pin 10 and gear shift guide block 3 gear selecting bulb draw-in grooves 14, gear selecting bulb 15.
Choosing, gear shift guide block 3 are provided with gear selecting bulb 15, gear selecting bulb draw-in groove 14, are provided with gear shift groove 12, gear selecting groove 13 on interlock board 4.
One, second gear shifting block 2 and, second gear shift fork link to each other, and three, fourth gear shifting block 5 and three, fourth gear shift fork link to each other, five grades, reverse gear shifting block 6 link to each other with reverse gear finger 7 with five grades, reverse speed fork.
The utility model gear selecting movement process is: choosing, gear shift guide block 3 is a neutral position as the residing position of Fig. 1, rotation gear selecting mechanism assembly 11, make on the gear selecting mechanism assembly 11 gear selecting bulb 15 in choosing, in the gear selecting bulb draw-in groove 14 of gear shift guide block 3, drive choosing, gear shifting assembly integral body is as shown in Figure 1 around choosing, shift shaft 9 angle that turns clockwise, three gear shift shifting blocks (2,5,6,) in gear selecting groove 13, move with respect to interlock board 4, to select, the unitary rotation of shift shaft assembly 8 is converted into each grade shifting block with respect to choosing, the translation of gear shift guide block 3, make choosing, the gear shift shifting block draw-in groove 16 of gear shift guide block 3 aims at one, second gear shifting block 2, just choose one smoothly this moment, two gears.Five grades, the selection of reverse gear position are to be rotated counterclockwise an identical angle at neutral position to get final product.
The utility model gear shift movement process is: be example with the neutral gear, rotation choosing, shift shaft assembly 8 also make the straight pin that changes on choosing, the shelves axle assembly 8 drive choosing, gear shift guide block 3 as accompanying drawing 2, shown in Figure 3 moving up in shift shaft straight pin draw-in groove 15, the gear shift shifting block draw-in groove 16 of this moment choosing, gear shift guide block 3 aims at three, fourth gear shifting block 5 and stir three, fourth gear shifting block 5 makes progress translation gear shift groove 12 in, translation one segment distance puts into fourth gear.Oppositely move and then hang third gear.If changing other gear then should first gear selecting, then gear shift.
