Embodiment
As shown in Figure 1, O, O1, O2 point are respectively the axle center of driving shaft and two countershafts of speed changer, three respectively by Bearing Installation on case of transmission.Wherein a countershaft is provided with the gear shift fork 11 of 1/2 retaining and the gear shift fork 12 of 5/6 retaining, and another root countershaft is provided with the gear shift fork 14 of back fork 13 and 3/4 retaining.
In conjunction with Fig. 1, Fig. 2, the utility model comprises a shifting axle 15, and is enclosed within the shifting sleeve 1 on the shifting axle 15.One end of fixed row's pin 2, block selecting return pin 3, neutral position switch 4, interlocking plunger 5 and the switch 6 that reverses gear all is equipped with ball, and the other end all is fixedly mounted on the case of transmission, and the spring that can stretch is equipped with in inside.Gearshift Rocker arm assembly 16 is fixedly connected on an end, block selecting Rocker arm assembly 8 and 9 ends that are connected shifting sleeve 1 of manipulation seat housing thereof of shifting axle 15 by resilient key 7.Protrude a Spin Control pin 10 on the cylinder of shifting axle 15.
In conjunction with Fig. 3, Fig. 4, two gearshift shifting blocks 23,25 are arranged on the shifting sleeve 1, all one-body molded on the homonymy cylinder of shifting sleeve 1.Wherein, gearshift shifting block 23 can contact and stir the gear shift fork 12 of gear shift fork 11,5/6 retaining of 1/2 retaining respectively, and gearshift shifting block 25 can contact and stir the gear shift fork 14 of back fork 13,3/4 retaining respectively.
With gearshift shifting block 23, be provided with successively vertically on the cylinder of 25 relative opposite side shifting sleeves 1 and decide emissions groove 18, V-shaped groove 19, neutral groove 20, the interlock slot 21 and the projection 22 that reverses gear, respectively with fixed row's pin 2, block selecting return pin 3, neutral position switch 4, the interlocking plunger 5 and the switch 6 that reverses gear are corresponding one by one, because fixed row's pin 2, block selecting return pin 3, neutral position switch 4, resilient balls all is equipped with in the end of the interlocking plunger 5 and the switch 6 that reverses gear, therefore they can form Elastic Contact, scalable when work, when realizing different functions, guarantee the smoothness and the accuracy of shifting operation.Wherein, V-shaped groove 19 is made of two sections conical surfaces and one section cylinder, and two sections conical surfaces constitute the inclined-plane of V-shaped groove both sides; Interlock slot 21 is H door shape.
The shifting sleeve is provided with a Spin Control groove 27 of offering vertically and the mobile control flume 26 that the edge is circumferentially offered, Spin Control pin 10 on the shifting axle 15 can endwisely slip in Spin Control groove 27, thereby shifting sleeve 1 and shifting axle 15 can only together be rotated, but allow shifting sleeve 1 with respect to shifting axle 15 endwisely slip (shifting axle 15 need not move axially); Moving control pin 17 (see figure 2)s on the block selecting Rocker arm assembly 8 inserts in the mobile control flume 26, thereby block selecting Rocker arm assembly 8 can spur the shifting sleeve and move axially block selecting, but when shift gears Rocker arm assembly 16 drive shifting sleeves 1 and shifting axle 15 together rotate gearshift, can relatively rotate again between block selecting Rocker arm assembly 8 and the shifting sleeve 1, make block selecting Rocker arm assembly 8 unaffected.There is an auxiliary hole 24 at the back side of Spin Control groove 27, is used for Spin Control pin 10 rivet clasps at shifting axle 15.
Fixed row's pin 2 matches with decide emissions groove 18, and the shifting block 23,25 that can guarantee to shift gears accurately cooperates with gear shift fork 11,12,13,14 accordingly, prevents automatic off-gear, and the widths over teeth of assurance gear meshes, and makes shift feel more clear.
Block selecting return pin 3 cooperates with V-shaped groove 19, can make the effect that self-return is arranged after the speed changer block selecting.
When speed changer was in neutral, neutral position switch 4 just in time contacted with neutral groove 20, and neutral pilot lamp is bright, transmitted the neutral signal.
In the whole shifting process interlocking plunger 5 all can be in the interlock slot 21 of H door shape slide relative, to guarantee that gearshift shifting block 23,25 can accurately contact with corresponding gear shift fork 11,12,13,14, and prevent that the mistake extension from reversing gear, thereby improve the accuracy and the smoothness of shifting operation.
Hang when reversing gear when speed changer, the switch 6 that reverses gear will contact with the projection 22 that reverses gear, and the tutorial light that reverses gear is bright, transmits the signal that reverses gear.
The utility model can pass through integral type shifting tube-in-tube structure, to decide emissions groove 18, V-shaped groove 19, neutral groove 20, interlock slot 21, reverse gear projection 22 and gear shift fork 23,25 all become one, simplify the structure greatly, reduced the quantity of part, improved the harmony and the reliability of mechanism action, realized shifting control and guarantee safety, and because all latch form connections to match of these component, be convenient to assembling, and reduce manufacture cost.
The utility model operating process is as follows: block selecting drag-line pulling block selecting Rocker arm assembly 8, driving shifting sleeve 1 axially moves, gearshift shifting block 23,25 can cooperate with different gear shift forks 11,12,13,14, carries out block selecting, and put for choosing 3/4 gear position shown in Figure 1.Block selecting return pin 3 is because the effect that makes shifting sleeve 1 self-return is played in the two places conical surface effect of V-shaped groove 19.When shifting sleeve 1 when position shown in Figure 1 continues to move right, gearshift shifting block 23 and 1/2 keeps off shift fork 11 and contacts, for choosing 1/2 retaining state; Shifting sleeve 1 continues motion more to the right, and gearshift shifting block 25 contacts with back fork 13, and speed changer is hung into reversing gear, and the switch 6 that reverses gear will contact with the projection 22 that reverses gear, and the tutorial light that reverses gear is bright.When gearshift drag-line pulling gearshift Rocker arm assembly 16, shifting axle 15 is done circumferentially to rotate, and shifting sleeve 1 also can rotate in a circumferential direction, and gearshift shifting block 23 or 25 is stirred corresponding gear shift fork 11,12,13,14, hangs corresponding gear.
Adopt the utility model, when manual transmission is worked, not only can satisfy functional requirement, guarantee that the driver can make speed changer hang into needed arbitrary gear work accurately and reliably, and can fall back on neutral automatically after gearshift, and shifting feels more steady more laborsaving; Simultaneously, the shifting tube-in-tube structure of integrated form is more coordinated reliably the action of each functional part, and speed changer can reduce number of spare parts again in making production process, and good manufacturability is convenient to assembling, reduces manufacture cost.
