Description
Technical field
The utility model relates to a kind of mechanical changeover mutual interlocking gear of many gears manual transmission of gear number >=3.
Background technique
Common gearshift self-locking mechanism is automotive transmission structure used substantially at present.Because automotive transmission structure, volume etc. are all less, selector fork mechanism is relatively light and handy, and gear level be straight line motion switching when gear substantially, generally realizes the interlocking between each gear by being arranged at interlocking plunger in housing etc.And for medium-and-large-sized manual transmission, shifting fork mechanism volume, weight etc. are all larger, when gearshift, be difficult to realize by the straight line motion of gear level, the each gear level of general using rotatablely move to realize the switching between gear, when gear level rotatablely moves, the mutual interlocking gear of original automotive transmission can not be suitable for.
Model utility content
The purpose of this utility model is to overcome the deficiency that prior art exists, and the mechanical interlocking mechanism of many gear gearshifts of a kind of manual, many gears (gear number >=3), the gearshift of many rotatable handles is provided.
The purpose of this utility model completes by following technical solution, a kind of mechanical interlocking mechanism of many gears gearshift, and it mainly includes the declutch shift shaft of two adjacent horizontal, and a side end of these two declutch shift shafts is respectively fixed with shift handle; Described two declutch shift shafts are integral with interlocking dish type separately by flat key separately, and an interlocking plunger is installed between the interlocking dish that two neighbours put, and two interlocking dishes are respectively arranged with the arc groove inserting for interlocking plunger end with respect to the two ends of interlocking plunger.
It is upper that two described interlocking dishes and interlocking plunger are all installed in same gearshift seat, in the left and right gearshift direction of described two shift handles, is separately installed with position limit switch.
Interlocking dish described in the utility model is fixed on declutch shift shaft by flat key or spline etc., in the time of shift handle rotation gearshift, drives declutch shift shaft to rotate, and declutch shift shaft drives interlocking dish to rotate; When shift handle is vertical, be neutral position state, gearshift action rotatablely moving to the left or to the right for each handle; Gearshift seat is a part independently, has reduced difficulty and the processing cost of casing processing.
The utility model is specifically designed to medium-and-large-sized mechanical power-shift gearbox (gear number >=3); There is two or more tooth covers---shifting fork mechanism speed changer inside, and each tooth cover---shifting fork mechanism, as arranged without interlocking, may be worked because misoperation causes more than two gear simultaneously, thereby destroys gear-box.
The utility model, by a kind of mechanical interlocking mechanism of many gear gearshifts, has ensured that speed changer can only be in some gear work in the process of normal work effectively, has avoided the operation accident of multiple gears combination simultaneously; It has the features such as compactness simple and reasonable for structure, easy to operate, processing installation is simple and easy, and accurate positioning, reliable operation, rate of fault are extremely low.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is interlocking structure partial enlarged drawing described in the utility model.
Embodiment
below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1, the mechanical interlocking mechanism of many gear gearshifts described in the utility model, it mainly includes the declutch shift shaft 4,5 of two adjacent horizontal, and a side end of these two declutch shift shafts 4,5 is respectively fixed with shift handle 2,3; The flat key 8,9 of described two declutch shift shafts 4,5 by separately and interlocking dish 6,7 formation one separately, between the interlocking dish 6,7 that two neighbours put, an interlocking plunger 10 is installed, and two interlocking dishes 6,7 are respectively arranged with the arc groove inserting for interlocking plunger 10 ends with respect to the two ends of interlocking plunger 10, as shown in Figure 2.
Two described interlocking dishes 6,7 and interlocking plunger 10 are all installed on same gearshift seat 1, in the left and right gearshift direction of described two shift handles 2,3, are separately installed with position limit switch 11,12,13,14.
embodiment: shown in Fig. 1, described many gear gearshift mechanical interlocking mechanisms (taking four-speed gear shift device as example) are mainly by gearshift seat 1, shift handle 2, shift handle 3, declutch shift shaft 4, declutch shift shaft 5, interlocking dish 6, interlocking dish 7, flat key 8, flat key 9, interlocking plunger 10, position limit switch 11, position limit switch 12, position limit switch 13, position limit switch 14 compositions such as grade.(be illustrated as 3/4 gear structure, 5/6 gear structure etc. can be by that analogy; Simultaneously position limit switch, for selecting piece installing, can design corresponding electric control system by it, realizes another interlock mode---and electrical control interlocks, but the utility model relates to mechanical interlockedly, and therefore electrical control is not described herein in this article.) in the time that speed changer switches to a certain gear, such as shift handle 2 rotatablely moves to the left or to the right, shift handle 2 drives together rotation to the left or to the right of declutch shift shaft 4 in the process of rotation, declutch shift shaft 4 forms one by flat key 8 and interlocking dish 6, thereby drive interlocking dish 6 to rotatablely move to the left or to the right, in the process that interlocking dish 6 rotates, interlocking plunger 10 is pushed to right side simultaneously, coordinate with arc groove corresponding on interlocking dish 7, thereby make interlocking dish 7 by locking, declutch shift shaft 5 and shift handle 3 all can not rotate, now shift handle 3 will be all the time in vertical state, namely can only be at neutral gear position.When interlocking plunger should be noted in its side-to-side movement in when design, its length dimension must ensure that certain interlocking dish can rotate freely, and another interlocking dish can not rotate because interlocking plunger just snaps in the groove of lock collar.The diameter of interlocking dish is directly proportional to gear level angle of swing.
In the time that gear level 3 rotates, now gear level 2 can not rotate, the interlocking principle of mechanism ditto described in.By that analogy
The utility model is simple and reliable for structure, the state that the interlocked that design reaches is worked with the multiple gears of speed changer of having avoided misoperation to cause simultaneously.
