The utility model relates to field of mechanical technique, and it is mounted on the machinery such as forklift, specifically relates to a kind of two and moves back four and advance six speed transmission.
Background technique
Speed changer has housing, a driving shaft is arranged in housing, in housing, below driving shaft, also have the first driven shaft (advance shaft) and the second driven shaft (axle falls back), driving shaft is connected with the first driven shaft gear, driving shaft is connected with the second driven shaft gear, the first driven shaft and the second driven shaft have long vertically chute, the sliding gear that can slide along chute is arranged in chute, the 3rd axle is arranged below the first driven shaft and the second driven shaft, on the 3rd axle, gear is arranged, the first driven shaft is connected with the gear of the 3rd axle through sliding gear with the second driven shaft, in prior art, the gear be arranged on the first driven shaft and the second driven shaft is respectively three and one, such speed changer only has three forward gearss and back leg shelves, has awkward shortcoming.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, provide a kind of use more convenient, regulate the speed and more two move back four and advance six speed transmission.
The technical solution of the utility model is achieved in that two move back four and advance six speed transmission, comprise housing, a driving shaft is arranged in housing, in housing, below driving shaft, also have the first driven shaft and the second driven shaft, driving shaft is connected with the first driven shaft gear, driving shaft is connected with the second driven shaft gear, the first driven shaft and the second driven shaft have long vertically chute, the sliding gear that can slide along chute is arranged in chute, the 3rd axle is arranged below the first driven shaft and the second driven shaft, on the 3rd axle, gear is arranged, the first driven shaft is connected with the gear of the 3rd axle through sliding gear with the second driven shaft, on described housing, be provided with shift fork, it is characterized in that: four the first sliding gears are installed on described the first driven shaft, four the first sliding gears are arranged by as many as less from the number of teeth of the end to end of axle, on described the 3rd axle, has the gear with these four the first sliding gear couplings at least.
Further say, two the second sliding gears that the number of teeth is different are installed on described the second driven shaft, the gear of two and the second sliding gear coupling is arranged on described the 3rd axle.
Further say to also have through one or more variable-speed shafts below described the 3rd axle, gear is arranged and be connected with a joggle on the 3rd axle, adjacent variable-speed shaft.
Preferably technological scheme is: described variable-speed shaft is two.
Technique effect of the present utility model is: such two move back four advances six speed transmission and has more convenient, the more advantage of regulating the speed of use.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As Fig. 1, 3, 4, 5, shown in 6, two move back four advances six speed transmission, comprise housing 1, a driving shaft 2 is arranged in housing, in housing, below driving shaft, also have the first driven shaft 3 and the second driven shaft 4, driving shaft is connected with the first driven shaft gear, driving shaft is connected with the second driven shaft gear, the first driven shaft and the second driven shaft have long vertically chute 5, the sliding gear that can slide along chute is arranged in chute, the 3rd axle is arranged below the first driven shaft and the second driven shaft, on the 3rd axle, gear is arranged, the first driven shaft is connected with the gear of the 3rd axle through sliding gear with the second driven shaft, on described housing, be provided with shift fork, it is characterized in that: four the first sliding gears 6 are installed on described the first driven shaft, four the first sliding gears are arranged by as many as less from the number of teeth of the end to end of axle, on described the 3rd axle, has the gear with these four the first sliding gear couplings at least, with four the first sliding gears 6 of shift fork adjustment, act on respectively the gear on the 3rd axle like this, four gears are just arranged, at this moment with one retreats shelves totally five gears.
Further say, two the second sliding gears 7 that the number of teeth is different are installed on described the second driven shaft 4, the gear of two and the second sliding gear 7 coupling is arranged on described the 3rd axle, sidepiece figure as shown in Figure 1, at this moment be six gears, i.e. four forward gears, two back legs gears.
Further say to also have below described the 3rd axle on one or more variable-speed shaft 9, the three axles 8, adjacent variable-speed shaft 9 and gear is arranged and be connected with a joggle.The speed passed over from the first driven shaft and the second driven shaft like this can be adjusted, and realizes transferring the files and the dual functions of speed governing.
Preferably technological scheme is: described variable-speed shaft 9 is two, and sidepiece figure as shown in Figure 2.
Whole like this gearbox just has six axles, is preferred technological scheme.
