Embodiment
As shown in Figure 1, O, O1, O2 point are respectively the axle center of driving shaft and two countershafts of speed changer, and three are passed through Bearing Installation respectively 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 present invention includes a choosing gearshift axle 15, and be enclosed within the choosing gearshift sleeve 1 on the choosing gearshift axle 15.A fixed end of arranging 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 that selects gearshift axle 15 through resilient key 7, and block selecting Rocker arm assembly 8 and 9 of housings of manipulation seat thereof are connected the end of selecting gearshift sleeve 1.Protrusion one Spin Control pin 10 on the cylinder of choosing gearshift axle 15.
In conjunction with Fig. 3, Fig. 4, two gearshift shifting blocks 23,25 are arranged on the choosing gearshift sleeve 1, all one-body molded on the homonymy cylinder of choosing gearshift 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.
Be provided with successively vertically on the cylinder of the opposite sides choosing gearshift sleeve 1 relative and decide emissions groove 18, V-shaped groove 19, neutral groove 20, interlock slot 21 and the projection 22 that reverses gear with gearshift shifting block 23,25; Row's pin 2, block selecting return pin 3, neutral position switch 4, interlocking plunger 5 and the switch 6 that reverses gear are corresponding one by one respectively with calmly; Because resilient balls all is equipped with in fixed end of arranging pin 2, block selecting return pin 3, neutral position switch 4, interlocking plunger 5 and the switch 6 that reverses gear; Therefore they can form Elastic Contact; Scalable when work, when realizing different functions, guarantee to select the smoothness and the accuracy of gear shift operation.Wherein, V-shaped groove 19 is made up 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.
Choosing gearshift 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 choosing gearshift axle 15 can endwisely slip in Spin Control groove 27; Thereby choosing gearshift sleeve 1 and choosing gearshift axle 15 can only together be rotated, but allow choosing gearshift sleeve 1 with respect to choosing gearshift axle 15 endwisely slip (choosing gearshift 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; Sleeve moves axially block selecting thereby block selecting Rocker arm assembly 8 can spur the choosing gearshift; But when the Rocker arm assembly 16 of shifting gears drives choosing gearshift sleeves 1 and selects gearshift axle 15 together to rotate gearshift; Can relatively rotate again between block selecting Rocker arm assembly 8 and the choosing gearshift 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 choosing gearshift 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.
Whole select in the shift 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 accuracy and the smoothness that selects gear shift 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 present invention can will decide emissions groove 18, V-shaped groove 19, neutral groove 20, interlock slot 21 through integral type choosing gearshift tube-in-tube structure, reverse gear projection 22 and gear shift fork 23,25 all become one, and simplify the structure greatly; Reduced the quantity of part; Improved the harmony and the reliability of mechanism action, realized selecting gear shift control and guarantee safety, and because all latch form connections to match of these component; Be convenient to assembling, and reduce manufacture cost.
Operating process of the present invention is following: block selecting drag-line pulling block selecting Rocker arm assembly 8; Driving choosing gearshift 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 choosing gearshift sleeve 1 self-return is played in the two places conical surface effect of V-shaped groove 19.Elected gearshift sleeve 1 is when position shown in Figure 1 continues to move right, and gearshift shifting block 23 and 1/2 keeps off shift fork 11 and contacts, for choosing 1/2 retaining state; Choosing gearshift 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, choosing gearshift axle 15 is done circumferentially to rotate, and choosing gearshift 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 present invention, 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 after gearshift, can fall back on neutral automatically, and select shift feel more steadily more laborsaving; Simultaneously, the choosing of integrated form gearshift tube-in-tube structure 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.
