Description
Technical field
The utility model relates to a kind of storage battery Counterbalanced forklift.
Background technology
The type storage-battery balancing weight fork truck that existing market is sold (abbreviation fork truck) drive part power is many to be provided by single motor, so need larger electric current satisfy horsepower output when working, the controller cost is high; Motor easily generates heat, volume is large; For satisfying the moving velocity needs, so motor output will be passed to drive wheel by diff, semiaxis etc. through the conversion of drop-gear box speed ratio, can satisfy the fork truck driving functions; Traditional DC machine is owing to exist mechanical commutator, and easy to wear need of meeting generation spark and carbon brush regularly replaces in the working process; Brake system adopts traditional drum brake, the poor and operation effort of braking effect.
The utility model content
Purpose to be solved in the utility model is to simplify complete vehicle structure, raising driving efficiency, reduce trouble, reduces noise in the Vehicle Driving Cycle process, driving system long service life, a kind of like this novel storage battery Counterbalanced forklift of raising brake system reliability.
Realize that the above-mentioned purpose technical scheme is as follows:
A kind of storage battery Counterbalanced forklift, described storage battery Counterbalanced forklift structure comprises: drive system, vehicle body and annex, steering swivel system, hydraulic efficiency pressure system, brake system, handling maneuver system, electric control system, jacking system, it is characterized in that: described drive system adopts two relatively independent wheel hub motors, and each wheel hub motor is installed on respectively the body structure left and right sides.
Drive system adopts two relatively independent wheel hub motors, is used for f-w-d, adopts such structure, and whole driving system gearless is non-carbonate; By coder Real-Time Monitoring steering angle, by controller active adjustment left and right sidesing driving wheel rotating speed, realize the electronic differential function in travelling, by the control to vehicle heading and moving velocity of change-over swith and accelerator.
Further, described wheel hub motor is outer-rotor structure.
Further, described wheel hub motor is permanent magnetic brushless.
Further, described wheel hub motor is direct driving motor, motor internal gearless or other speed reduction gearings.
Further, the rotating speed of described wheel hub motor carries out step-less adjustment by controller.
Further, described wheel hub motor is regulated the rotation forward or backwards of wheel hub motor by controller.
Further, described brake system adopts the structure that hydraulic brake system combines with regeneration brake system.

Fig. 2 is a drive wheel assembly scheme drawing
The specific embodiment
Car load is comprised of drive system 1, vehicle body and annex 2, steering swivel system 3, hydraulic efficiency pressure system 4, brake system 5, handling maneuver system 6, electric control system 7, jacking system 8 etc.; Drive system 1, steering swivel system 3, handling maneuver system 6, hydraulic efficiency pressure system 4, brake system 5, electrical apparatus control system 7, jacking system 8 all are connected with vehicle body 2; Described drive system 1 is that two relatively independent wheel hub motors 10, wheel hub motor 10 are used for f-w-d, and wheel hub motor 10 is connected with wheel rim 13, wheel rim 13 is connected with tire 9; Trailing wheel is wheel flutter, and a side wheel flutter main shaft is equipped with coder, for detection of and feed back corner information; Drive system 1 adopts two relatively independent wheel hub motors 10 directly fork truck to be driven.Wheel hub motor 10 adopts permanent magnet brushless direct driving motors, and each wheel hub motor is installed on respectively the body structure left and right sides, and whole driving system is non-carbonate, gearless or other speed reduction gearings; By coder Real-Time Monitoring steering angle, regulate respectively the left and right sidesing driving wheel rotating speed by controller in travelling, realize the electronic differential function, further realize control to vehicle heading and moving velocity by change-over swith and accelerator via controller.Wheel hub motor preferably uses outer-rotor structure.
Brake system: the employing hydraulic braking sysgtem of the brake system uniqueness of this programme mode that regenerative brake combines of unifying, the application of this structure, in the effect that improves braking, reduced the loss of energy, when not accelerating in the driving process, wheel hub motor 10 is stopped power supply, thereby motor still rotates under the drive of vehicle inertia effect and produces the rotation of induced electric motive force prevention wheel hub motor until stop, motor will become an electrical generator this moment, the electric energy by-carriage that produces is returned storage battery, and energy all converts heat exhaustion to by brake friction and falls when braking unlike common forklift.Regenerative brake at first begins effect when stepping on brake pedal, and simultaneously hydraulic braking also participates in braking; It is sensitive that the preferred hydraulic tongs disc type brake of hydraulic brake system, hydraulic tongs disk braking system have braking, the large and uniform characteristics of lock torque; The hydraulic brake system main parts size has master cylinder, brake disc 12, brake assembly 11, oil pipe etc.Brake disc 12 is fixed on the wheel, with vehicle wheel rotation.Brake assembly 11 is fixed on vehicle body; When hydraulic brake system was worked, master cylinder (not shown) inside brake liquid produced pressure, and oil is pressed into brake assembly through oil pipe; The hydraulic action that the brake assembly piston is transported by oil pipe promotes the brake plate (not shown) and presses to brake disc generation friction braking, forces wheel to stop.The preferred hydraulic caliper-disc brake of brake assembly, this drg rapid heat dissipation, lightweight, simple structure, easy to adjust.Compare other braking, the easier shortening stopping distance of hydraulic tongs disc type brake, particularly resistance to elevated temperatures is good during high capacity, and braking effect is stable, and is not afraid of the greasy dirt invasion and attack, is fit to very much the applied environment of fork truck.
