Abstract
The utility model relates to an automobile-used speed change mechanism, it is based on the speed change mechanism of the agricultural tricycle transport vechicle of former belt drive, including the declutch shift shaft, arrange two epaxial shifting forks of same declutch shift and shift fork driving lever in, its main points are that the poker groove on two shifting forks is in when the neutral gear and establish body vertically same axis with the declutch shift shaft, and a shift fork driving lever of two shifting forks sharing, and fixed mounting is continuous with the gear lever that has the knuckle of float dress on the frame on the shift fork driving lever shaft of shifting fork driving lever is direct. The mechanism has simple structure and reliable use, and is particularly suitable for agricultural three-wheeled vehicles and modified vehicles.
Description
The utility model relates to a kind of automobile-used speed-changing mechanism, and it is particularly useful for bel-drivenn agricultural three-wheel transporter and amelioration product thereof.
At present, in commercially available bel-drivenn agricultural three-wheel transporter, the speed-changing mechanism that a kind of three-wheel vehicle is arranged is such, its two almost completely identical gear shift forks place on the same declutch shift shaft, the driving lever groove of shift fork all is located at its top, the axis of two grooves becomes parallel shape, realizes displacement by oneself shift fork driving lever and pull bar respectively.Because an end of pull bar links to each other with the dihedral revoliving arm on being fixed on vehicle frame, and the other end links to each other with the shift fork driving lever, the change speed gear box that the shift fork driving lever is housed as back axle is by leaf spring and the unsteady bonded assembly of vehicle frame, so,, also be the variation of vehicle frame and change speed gear box relative position usually, and cause pull bar pulling shift fork driving lever to make shift fork produce displacement because of unloaded or heavily stressed variation, thereby make speed-changing mechanism produce unexpected trip stop, promptly so-called disorderly shelves phenomenon.Like this, just bring many inconvenience, even therefore beyond thought accident can take place to the user.
The purpose of this utility model be to overcome the weak point in the above-mentioned technology and provide a kind of simple in structure, cost is low, use is reliable and the automobile-used speed-changing mechanism of easy-to-operate.
The purpose of this utility model is realized by following measure: a kind of automobile-used speed-changing mechanism, it is based on the speed-changing mechanism of the agricultural three-wheel transporter of former belt-driving, comprise declutch shift shaft, place two shift forks, shift fork driving lever and shift fork shift lever axis on the same declutch shift shaft, its main points are that two driving lever grooves on the shift fork are when neutral gear, be in declutch shift shaft to become on the vertical same axis of solid, and two shared shift fork driving levers of shift fork, the shift fork shift lever axis of fixed installation shift fork driving lever links to each other with the floating shifter bar that has steering swivel that is contained on the vehicle frame.
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:
Fig. 1 is that the local axle of this mechanism is surveyed scheme drawing.
Referring to Fig. 1, driving lever groove 4,10 on two shift forks 1,11 when neutral gear, be in 2 one-tenth three-dimensional vertical same axis of declutch shift shaft on, and two shift fork 1,11 shared shift fork driving levers 5, the shift fork shift lever axis 9 of fixed installation shift fork driving lever 5 links to each other with the floating shifter bar that has steering swivel 87 that is contained on the vehicle frame 6.Shift fork 1 is to increase a lateral bending arm 3 on the basis of former shift fork, and its driving lever groove 4 is located at the top, end of curved boom 3, and the driving lever groove 10 of itself and another shift fork 11 is on the same axis when neutral gear.Like this, when shift fork 11 relative declutch shift shafts 2 being moved to left by shifter bar 7, steering swivel 8, shift fork shift lever axis 9 and shift fork driving lever 5, promptly stir the respective gears engagement on reverse gearwheel 13 and the power take-off shaft, when shift fork 11 relative declutch shift shafts 2 are moved to right, promptly stir the respective gears engagement on one grade of gear 12 and the power take-off shaft, simultaneously, reverse gearwheel 13 is thrown off with engaging gear.In like manner, when making shift fork driving lever 5 be in the driving lever groove 4 of shift fork 1 by shifter bar 7, shift fork 1 is moved to left, second speed gear 15 jogglewords move to right shift fork 1,3rd gear 14 jogglewords.
This mechanism structure is simple, and cost is low, uses reliable and easy and simple to handle.
Claims (1)
1, a kind of automobile-used speed-changing mechanism, it comprises declutch shift shaft, place two shift forks, shift fork driving lever and shift fork shift lever axis on the same axle, the driving lever groove 4,10 that it is characterized in that said two shift forks 1,11 when neutral gear, be in 2 one-tenth three-dimensional vertical same axis of declutch shift shaft on, and two shift fork 1,11 shared shift fork driving levers 5, the shift fork shift lever axis 9 of fixed installation shift fork driving lever 5 links to each other with the floating shifter bar that has steering swivel 87 that is contained on the vehicle frame 6.
