Description
Technical field
The utility model belongs to mechanical power technical field, is specifically related to a kind of electric balancing weight fork truck retarder.
Background technology
Along with the raising of social environment consciousness, electri forklift is more and more widely used, the form of existing electric forklift speed reduction box mostly is bridge case integral type, namely axle reduction case and motor are that integral type is installed together, motor drives drive axle by retarder, on the wheel hub moment of torsion of electrical motor and Movement transmit are extremely connected with drive axle by drive axle, thus be delivered to tire, produce power, existing retarder is in order to meet the requirement of gear reduction, how to be solved by the method for multistage fixed shaft gear train deceleration, in so-called fixed shaft gear train and retarder, the axial location of each reducing gear maintains static, the transmitting ratio of fixed shaft gear train is the ratio of the number of teeth of two transmission gears, be characterized in by multistage transmission, the transmission of fixed shaft gear train can reach larger transmitting ratio, in commutation, speed change, the aspect also superior performances such as shunt transmission, so this transmission scheme of the many employings of existing retarder.
Nowadays, the flying power improving electri forklift becomes problem demanding prompt solution, and improve the volume that the most direct effective method of electri forklift flying power is increase battery, thus raising capacity, due to the limited space on electri forklift, want to vacate more wide space to install battery, just the volume of miscellaneous part must be reduced, retarder is the critical component on electri forklift, the volume size of this part also occupies a sizable part, because the train of the reducing gear of existing retarder mostly is fixed shaft gear train, so its volume is general very large, compared to fixed shaft gear train, planet circular system can obtain very large transmitting ratio with minority gear, therefore it is compacter than fixed shaft gear train, much light.Planet circular system has the unexistent Some features of fixed shaft gear train, and therefore it not only has the feature of fixed shaft gear train, also has the feature that oneself volume is less, structure is compacter.The retarder of electri forklift can be made more compact, light by the compound use of planet circular system and fixed shaft gear train.
Existing bridge case integral type speed reducer assembly, retarder due to most of electri forklift is all connect the transmission of realization and wheel hub by bridging, it is that the moment of torsion of reducer output shaft and motion are reached the device of wheel hub by the semiaxis by being provided with finishing bevel gear cuter that so-called bridging connects, due to the existence that bridging connects, make the volume of the volume of electri forklift installation battery more narrow and small, also make the part of electri forklift increase, structure is more complicated, and productive costs is larger simultaneously.
Except retarder and bridging junctor amass greatly, existing electri forklift and mostly be back-wheel drive, because load when fork truck works is very large, front-wheel almost carries the weight of all goods, in this case, if front-wheel bear turn to just be easy to damage turning member.
In sum, existing electri forklift carries out slowing down and the existence that connects of bridging due to multiplex fixed shaft gear train, so there is the excessive shortcoming of bridge case one assembly volume more, the volume of battery is caused to reduce, capacity is too small, because present electri forklift is back-wheel drive, so existing electri forklift can not meet fork truck running freely safe in narrow and small, that load is large working environment.
Utility model content
(1) technical matters that will solve
Common bridge case one reductor assembly adopts drop-gear box and bridge connecting mode, and adopts fixed shaft gear train to slow down, so drop-gear box volume is large, part is many, and semiaxis need be had when bridging connects to connect with wheel hub, and there is volume large, part is many, the shortcoming that cost is high.The utility model overcomes that existing bridge case integrated retarder volume is large, part is many, the shortcoming that need connect with wheel hub with semiaxis, the technical matters solved is to provide a kind of compact conformation, volume is little, and retarder directly connects with wheel hub, without transition portion and the large retarder of output torque.
(2) technical scheme
In order to solve the problems of the technologies described above, the utility model provides so a kind of electric balancing weight fork truck retarder, includes reducer shell, planet circular system;
Planet circular system is arranged on reducer shell, and planet circular system input end connects with existing motor, and the mouth of planet circular system connects with existing hub spindle.
Preferably, described planet circular system is made up of one-level star-wheel train and secondary planet train.
Preferably, primary planet train includes one-level sun wheel, primary planet pinion, a pole gear ring, primary planet supporting disk, primary annulus is arranged on reducer shell, primary planet pinion engages with primary annulus and one-level sun wheel, and primary planet pinion is connected with primary planet supporting disk.
Preferably, secondary planet train includes secondary solar gear, secondary planetary gear, secondary gear ring, secondary planet supporting disk, secondary gear ring is arranged on reducer shell, secondary planetary gear engages with secondary gear ring and secondary solar gear, and secondary planetary gear is connected with secondary planet supporting disk.
Preferably, the primary planet supporting disk of primary planet train connects with the secondary solar gear of secondary planet train, and primary planet supporting disk drives secondary solar gear to rotate.
Preferably, the secondary planet supporting disk of secondary planet train directly connects with hub spindle, and hub spindle connects with tire, eliminates bridging and connects, directly power is reached tire.
Principle of work: one-level sun wheel one end connects with motor, and the other end connects with primary planet pinion, and by transmission of power to secondary planetary gear, secondary planetary gear is passed to hub spindle, and hub spindle connects with tire, directly exports.Transmission adopts two-stage planet transmission, and compared to the type of drive adopting fixed shaft gear train, structure is lighter, compact, and space is less, and output torque is larger.Planetary power is directly reached on hub spindle, eliminates bridging and connect, further reduce again the volume of bridge case one assembly, make structure compacter, decrease parts simultaneously, make structure more simple, saved productive costs.
(3) beneficial effect
Transmission adopts two-stage planet transmission, and compared to the type of drive adopting fixed shaft gear train, structure is lighter, compact, and space is less, and output torque is larger.Planetary power is directly reached on hub spindle, eliminates bridging and connect, further reduce again the volume of bridge case one assembly, make structure compacter, decrease parts simultaneously, make structure more simple, saved productive costs.So in sum, the utility model efficiently solves the problem in space, does not need bridging to connect, drop-gear box adopts Planetary Gear Transmission, and structure is more compact, has driving torque large, the feature that volume is little.
