Abstract
The electric hydraulic fork truck has one set of middle transition wheels between the front wheels and the back wheels and front wheel driving. The technical scheme is as follows: a gear differential is arranged between the driving motor and the front wheel, two sides of the gear differential are respectively provided with a bidirectional overrunning clutch, the output end of the bidirectional overrunning clutch is provided with a driving chain wheel, and the front wheel and the intermediate transition wheel are respectively provided with a driven chain wheel. The power transmission sequence is that the motor drives the gear differential mechanism, the gear differential mechanism respectively transmits power to the two-way overrunning clutch to two sides, the two-way overrunning clutch drives the driving chain wheel to transmit the power to the middle transition wheel and the front wheel of the electro-hydraulic forklift through the chain, and the front wheel driving of the electro-hydraulic forklift is realized.
Description
Technical Field
The utility model relates to a high car, especially the hydraulic pressure that can full electric power help walking are piled to hydraulic pressure.
Background
At present, a hydraulic fork lift truck is widely applied to industries such as industry, storage, logistics and the like as a hydraulic power-assisted lifting and moving tool device. Great convenience is brought to stacking, short-distance moving, tool and die installation, cargo handling and the like of small heavy objects and cargos in the industries. However, the existing hydraulic forklift generally has the defects of low manual operation lifting speed, difficulty in moving after loading and the like. In addition, the fork lift truck is generally close to the ground, and is very easy to support the bottom when the ground is uneven or enters or exits a workshop doorway or the road surface has slopes and other terrains. Although the existing electric hydraulic fork lift truck solves the problems of slow lifting and manual operation, the rear wheels of the fork lift truck have dual functions of walking driving and steering operation, and the rear wheels of the fork lift truck have the functions of steering and walking driving in use, so that the electric fork lift truck generally has the problems of complex structure, heavy body, heavy self, inflexible operation, difficult operation and the like.
Disclosure of Invention
In order to solve the problems of the hydraulic fork lift truck in the current market, the utility model provides a novel electric hydraulic fork lift truck, aiming at the problems reflected in the actual use of various hydraulic fork lift trucks at present, the truck body structure and function distribution of the hydraulic fork lift truck are re-optimized, the dead weight of the truck body is reduced, the lifting speed is improved, the operation is convenient, thereby greatly reducing the labor intensity of workers and improving the use efficiency of equipment,
the utility model discloses the technical scheme who adopts is, piling the turning to of high car with electronic hydraulic pressure and has carried out the separation from functional design with the walking drive function, and the front wheel design that will pile the high car is for taking differential walking drive wheel, and the rear wheel only undertakes the function that turns to, simultaneously because the main weight load of high car is piled to hydraulic pressure, and the most is concentrated on the front wheel, can effectively improve the response speed that electronic heap high car walked with the front wheel drive. In addition, a middle auxiliary wheel is additionally arranged between the front wheel and the rear wheel of the forklift, so that the problem that the chassis of the forklift is too low and is easy to support the bottom is solved.
The utility model has the advantages that: through changing the design structure of the walking drive and the steering control of the existing electric fork lift truck, the walking drive and the steering control of the electric fork lift truck are separated, so that the direction maneuverability and the flexibility of the electric fork lift truck are improved, and the walking response speed of the electric fork lift truck is improved. Meanwhile, the middle auxiliary wheel is additionally arranged, so that the problem of bottom support of the fork truck is solved, the adaptability of the electric fork truck to the use environment is improved, and the labor intensity of workers is reduced. The production efficiency is improved.
Drawings

FIG. 2 is a back view of the electro-hydraulic fork lift truck
Reference numerals: the hydraulic forklift comprises a driving motor 1, a gear differential 2, a transmission shaft 3, a bidirectional overrunning clutch 4, a driving chain wheel 5, a middle auxiliary wheel 6, a transmission chain 7, a front wheel 8, a rear wheel 9, a lifting fork lifting button 10, a forward/backward button 11, an electric hydraulic forklift lifting mechanism, a battery and a controller, and is characterized in that an integrated cabinet, a lifting fork 13 and a lifting fork lifting oil cylinder 14 are installed on the electric hydraulic forklift lifting mechanism, the battery and the controller.
Detailed Description
As shown in fig. 2, the electric hydraulic fork lift truck of the present invention is equipped with a driving motor 1, a gear differential 2, a transmission shaft 3, a bidirectional overrunning clutch 4, a driving sprocket 5, a middle auxiliary wheel 6, a transmission chain 7, and a front wheel 8 with a driving function on the basis of the conventional hydraulic fork lift truck structure. The interaction function and the connection relation are that the gear differential 2 is driven after the speed is reduced by the driving motor 1, the function is to balance the rotation speed difference between the inner side and the outer side generated when the electric hydraulic fork lift truck turns, then the gear differential 2 drives the rotation speed difference required by the front wheel according to the two sides, and the differential is respectively and differentially transmitted to the bidirectional overrunning clutches 4 at the two sides, the bidirectional overrunning clutch has the function of separating power units such as the motor and the differential from the front driving wheel under the use state of manual pushing, so as to reduce the strength when the electric hydraulic fork lift truck is pushed by manpower, reduce the physical burden of an operator, and then drive a transmission chain 7 through a driving chain wheel 5 arranged on the output shaft of the bidirectional overrunning clutch 4, drive a middle auxiliary wheel 6 and a front wheel 8, and realize the automatic walking of the electric hydraulic fork lift truck.
Claims (2)
1. The utility model provides an electronic hydraulic pressure heap high car, in this electronic hydraulic pressure heap high car's traveling system, except installing drive motor, still installed gear differential, two-way freewheel clutch and middle auxiliary wheel, characterized by: the front wheels of the electric hydraulic fork truck are walking driving wheels.
2. The electro-hydraulic fork lift truck of claim 1, wherein: an intermediate auxiliary wheel is respectively arranged between the front wheel and the rear wheel on the two sides of the electric hydraulic fork lift truck.
