Description
Technical field
The utility model relates to a kind of fork truck, relates in particular to two four pivot electric forklifts that drive of a kind of large-tonnage.
Background technology
The principal parameter of reflection fork truck manoevreability is the minimal channel width of fork truck right angle stacking, and namely fork truck is for picking and heap goods, needed minimum beeline channel width while doing 90 ° of turnings on the beeline channel between goods is stamped.
Comparatively speaking, three pivot electric forklifts can be realized 90 ° of pivot studs, in office operation light and flexible more.From the purchase cost analysis, three pivot electric forklifts generally are used in the narrower place of indoor channel, therefore require the design compact, generally adopt the Europe superscript storage battery, and cost is higher; Simultaneously, three 90 ° of pivot electric forklifts turn to need to use and can support the rotating swing bearing of trailing wheel, and therefore the integral vehicle cost of three pivot electric forklifts is higher.Four pivot electric forklifts are because adopt maturation supporting, and cost is lower than three fulcrum forklifts.And the stability of four pivot electric forklifts is better than three pivot electric forklifts, but because the reason of structure can not realize pivot stud, so turn radius is large, in tunnel during operation required passage wider.
Therefore, will be higher than four pivot electric forklifts with the price of tonnage three pivot electric forklifts.But because it is subject to the restriction of stability, three fulcrum forklifts are general multiplex in lifting below 2 tons, and the fork truck more than 2.5 tons is all generally four fulcrums, along with expanding economy, land resources is more and more expensive, with the fork truck turn radius size phase specific energy of tonnage, saves nearly 30% storage space.The utility model provides a kind of large-tonnage two four fulcrum forklifts that drive.
Summary of the invention
The utility model, for deficiency of the prior art, provides a kind of propulsive effort by force and two four pivot electric forklifts that drive of the large-tonnage of flexible structure.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Two four pivot electric forklifts that drive of large-tonnage, comprise drive system, steering swivel system and vehicle frame, vehicle frame comprises car body ante-chamber and car body back cavity, drive system comprises controller, drive motor, change speed gear box and drive wheel, described controller is controlled respectively two drive motor, and two drive motor connect respectively two change speed gear boxs, and two change speed gear boxs connect two drive wheels, two drive motor are arranged side by side in the car body ante-chamber, and controller is located at the car body back cavity.Take full advantage of space and arrange, make framework compacter, the car load crossing ability is strong.
As preferably, steering swivel system comprises steeraxle, turns to potential device and wheel flutter, wheel flutter is connected with steeraxle, on steeraxle, be equipped with and turn to potential device, turn to potential device that the corner information of wheel flutter is reached to controller, the rotating speed that controller is controlled two drive motor according to size and the direction of deflection angle, rotating speed size, stall or the backward rotation of control drive motor.
As preferably, wheel flutter and steeraxle are bolted.
As preferably, the rotational angle of wheel flutter is 180 ° to the maximum.
As preferably, the angle between steeraxle and wheel flutter is 75-255 °.
As preferably, between car body ante-chamber and car body back cavity, with grand bone, with vehicle frame, be connected square steel and connect.
As preferably, but the vehicle frame side is provided with the side door of folding, side door in-built electrical bottle stopper plate, and bottom of frame is provided with idler assembly.
As preferably, above vehicle frame, be provided with safe ceiling.
The beneficial effects of the utility model are: the Dual-motors Driving powerful, and hill climbing ability is strong; It is compacter that drive system takies the car load space, makes enough spaces arrange storage battery, and the storage battery center-of-gravity position can arrange minimum, and stability is better.Compare conventional four fulcrum forklift designs, the angle of the single tyre rotation of its back axle is larger, can reach 180 °, has realized that the car load original place is around front two drive wheel center-point revolution actions, and turn radius is less, and car load is more flexible.
