The specific embodiment
The car of the utility model is used selector, in design, mainly is through the block selecting bulb on the gear level block selecting drag-line to be applied application force, promotes change-speed box block selecting rocking arm by the block selecting drag-line, realizes the block selecting action; Move alternately with block selecting; Through the gearshift bulb on the gear level gearshift drag-line is applied application force; Promote the shift of transmission rocking arm by the gearshift drag-line; Realize the gearshift action, its Alternation Display structurally is: when the block selecting action took place, the position before the relative block selecting action of gearshift bulb takes place did not produce displacement; When the gearshift action took place gear level, the position before the block selecting bulb takes place with respect to the gearshift action did not produce displacement.
Know by Fig. 1-shown in Figure 3; Car in the present embodiment is used selector; Comprise gearshift support 1, be arranged on the gear level 2 on the gearshift support 1, gear level 2 cooperates with gearshift support 1 through gearshift bearing 3 and links to each other, and is fixed with block selecting bulb 4 and gearshift bulb 5 on the gear level 2.
Wherein, the top of gearshift support 1 is provided with the U-shaped frame.Gear level 2 bottoms are provided with two block selecting pawls 21 and a gearshift pawl 22, and the line between these two block selecting pawls 21 overlaps with the block selecting direction, and block selecting bulb 4 is fixedly installed on the outside of one of them block selecting pawl 21; Gearshift pawl 22 is arranged on the midperpendicalar of line between two block selecting pawls 21, and gearshift bulb 5 is fixedly installed on gearshift pawl 22 outsides.
Can find out in conjunction with Fig. 4, Fig. 5; Be provided with block selecting mandrel hole 31 and gearshift mandrel hole 32 in the gearshift bearing 3, gearshift mandrel hole 32 is positioned at the top in block selecting mandrel hole 32, and the two right-angled crossing is provided with; But the two no point of crossing, promptly the two macro manifestations spatially is the right-angled crossing hole.Can clearly find out by Fig. 3; In the block selecting mandrel hole 31 of gearshift bearing 3, penetrate a block selecting mandrel 6 that can in block selecting mandrel hole 31, rotate; Two sides of the two ends of block selecting mandrel 6 and U-shaped frame are connected, and the central lines of the axis of block selecting mandrel 6 and gearshift bulb 5 is when so promptly having formed the bearing 3 of shifting gears and on the U-shaped frame, locate; Can serve as that axle rotates also with block selecting mandrel 6; Certainly, in order to ensure the realization of this rotation, the bottom surface of gearshift bearing 3 should and the inner volume of U-shaped frame bottom between leave certain spacing; In gearshift mandrel hole 32, penetrate a gearshift mandrel 7 that can in gearshift mandrel hole 32, rotate; The two ends of gearshift mandrel 7 and two block selecting pawls 21 of gear level 2 are connected; The axis of gearshift mandrel 7 and the central lines of block selecting bulb 4; So promptly having formed gear level 2 on gearshift bearing 3 in the location, can be axle with gearshift mandrel 7 also, together with shifting gears mandrel 7, and bearing 3 rotates relative to shifting gears.
Stretch out at block selecting mandrel 6 between the side of an end, gearshift bearing 3 and U-shaped support of gearshift bearing 3, be provided with one be sleeved on the block selecting mandrel 6, with the fixed block 82 that the bearing 3 of shifting gears is connected, can find out by Fig. 4, Fig. 5; The gabarit of this fixed block 82 is a circle; Be set with torsion spring 8 on it, on the outer wall of gearshift bearing 3, also be fixed with catch 81, one of them of torsion spring 8 turns round arm and catch 81 is connected; Another turns round arm and the U-shaped plate is connected; Having realized that torsion spring 8 links to each other with cooperation between the gearshift bearing 3, added this structure, mainly is in 3 generations of gearshift bearing during with respect to the change in location of neutral; Torsion spring 8 provides a limiting force for gearshift bearing 3 or returns back to the restoring force of neutral, and this power is being block selecting sense power or gearshift sense power to the performance in operator's block selecting or the shift process.
In use, the operator operates gear level 2 and carries out the block selecting action, and it is axle with block selecting mandrel 6 that gear level 2 drives gearshift bearing 3; Rotate relative to gearshift support 1, block selecting bulb 4 relative neutral gear positions produce displacement, because this displacement; Make with block selecting bulb 4 bonded assembly block selecting drag-lines and promote change-speed box block selecting rocking arm, realize the block selecting action, in this block selecting course of action; Because the central lines of the axis of block selecting mandrel 6 and gearshift bulb 5; So gearshift bulb 5 is that axis carries out rotation with the line of centers of self only, and is not subjected to displacement, the position of the bulb 5 of just shifting gears does not change; Gear shift operation is carried out in block selecting bulb 4 positions based on after this block selecting action completion, and the operator operates gear level 2, and gear level 2 drives gearshift mandrels 7 and in block selecting bearing 3, rotates; Gearshift bearing 3 does not produce any displacement in this rotation process, and gear level 2 drives gearshift bulb 5 and produces displacement, because this displacement; Bulb 5 bonded assemblys gearshift drag-line promotion shift of transmission rocking arm realization gearshift action makes and shifts gears; In this course of action, because the axis of gearshift mandrel 7 and the central lines of block selecting bulb 4, so block selecting bulb 4 is that axis carries out rotation with the line of centers of self only; But do not produce displacement, just the position of block selecting bulb 5 does not change.
