Abstract
The utility model relates to the technical field of special motor vehicles, in particular to a dual-function gear transmission device of an electric forklift. The dual-function gear transmission device of the electric forklift comprises a transmission shaft, a transmission shaft supporting frame, a big gear and a pinion. The dual-function gear transmission device of the electric forklift is characterized in that a bearing bush is installed on the transmission shaft supporting frame, a bearing is installed in the bearing bush, the transmission shaft is installed in the bearing bush and supported by the bearing, the transmission shaft is provided with a key groove, the pinion and the big gear are installed on the transmission shaft through keys, one end of the transmission shaft is supported by a bearing support installed on a bottom plate of the transmission shaft supporting frame and the bearing, and the other end of the transmission shaft is also provided with a key groove which is used for being connected with a driven device. According to the dual-function gear transmission device of the electric forklift, the function that a single motor outputs different driving forces is achieved, a lifting mechanism and a traveling mechanism can be driven simultaneously, and compared with traditional double-motor arrangement, cost is lowered, complexity is also lowered, and reliability is improved.
Description
Technical field
The utility model relates to a kind of special machine motor-car technical field, the specifically difunctional gear driver of a kind of electri forklift.
Background technique
Current known electric fork truck transmission system is to drive respectively oil pump to realize the action that hoists and travel by two direct current generators, and such drive system structure is larger, and relatively complicated, cost is high, because increasing of part also reduced reliability.
Summary of the invention
The purpose of this utility model is to provide a kind of the single motor of need and can drives the difunctional gear driver of electri forklift of hoist motion and the motion that travels.
The utility model comprises transmission shaft, transmission shaft supporting frame, gearwheel, small gear, on transmission shaft supporting frame, bearing housing is installed, bearing is installed in bearing housing, transmission shaft is arranged in bearing housing and is supported by bearing, on transmission shaft, have keyway, small gear and gearwheel are arranged on transmission shaft by key, and one end of transmission shaft is supported by the bearing spider and the bearing that are arranged on transmission shaft supporting frame base plate, the transmission shaft the other end also has keyway, for connecting driven equipment.
The utility model has the following advantages compared with prior art:
The difunctional gear driver of electri forklift of the present utility model has been realized by single motor, exports the function of multiple different driving forces, can drive lifting mechanism and traveling mechanism simultaneously, compared with the configuration of traditional double motor, reduce cost, lowered complexity, promoted reliability.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the difunctional gear driver generalized section of electri forklift of the present utility model.
Fig. 2 is the difunctional gear driver stereogram of electri forklift of the present utility model.
In figure: 1. bearing spider, 2. small gear, 3. gearwheel, 4. transmission shaft, 5. transmission shaft supporting frame, 6. bearing housing.
Embodiment
The utility model comprises transmission shaft 4, transmission shaft supporting frame 5, gearwheel 3, small gear 2, bearing housing 6 is installed on transmission shaft supporting frame 5,6 li of bearing housings are provided with bearing, transmission shaft 4 is arranged on 6 li of bearing housings and is supported by bearing, on transmission shaft 4, have keyway, small gear 2 and gearwheel 3 are arranged on transmission shaft 4 by key, one end of transmission shaft 4 is supported by the bearing spider 1 and the bearing that are arranged on transmission shaft supporting frame 5 base plates, transmission shaft 4 the other ends also have keyway, for connecting driven equipment.
When use, with gear, gearwheel 3 is connected with motor, driven by motor gearwheel 3 rotates, gearwheel 3 drives transmission shaft 4 to rotate, transmission shaft 4 drives small gear 2 to rotate simultaneously, small gear 2 connects by gear and drives traveling mechanism, and transmission shaft 4, by the keyway of its other end, is connected with oil pump simultaneously, drive lifting mechanism, realized the function of single motor dual output.
