Abstract
The invention discloses an electric fork-lift truck steering device which comprises a steering wheel, a steering column, a cardan joint, a steering actuating device, a carframe and a shift wheel, wherein the steering column is arranged below the steering wheel and is connected with the steering wheel. The cardan joint is arranged below the steering column and is connected with the steering column. The steering actuating device is connected with the cardan joint. The carframe is connected with the steering actuating device. The shift wheel is arranged on the carframe. The steering actuating device comprises a chain wheel mechanism and the steering wheel, wherein the horizontally arranged steering is connected with the cardan joint through the chain whell mechanism. The carframe comprises a vertical part and a horizontal part, wherein the horizontal part is connected with the bottom end of the vertical part. The top end of the vertical part of the carframe is fixedly connected with the end face of the steering wheel. The horizontal part of the carframe is provided with the shift wheel. The electric fork-lift truck steering device has the advantages of being simple in structure, convenient to operate and low in cost. In the process of steering, a driver can adjust angles of the shift wheel by constantly steering the steering wheel according to factors such as road surface bending changes and speed changes to maintain steering tracks which a driver wants to reach, and therefore the electric fork-lift truck steering device is reliable in steering, and low in stoppage rate and the like.
Description
Technical field
The present invention relates to a kind of steering hardware of battery-driven car, specifically a kind of electri forklift steering hardware.
Background technology
When common mechanical type steering swivel system need to turn to, chaufeur applies a steering torque to steering handwheel, this moment is by the steering shaft input steering gear, there is deceleration transmission secondary in the deflector as reduction gear apparatus, tierod is passed in motion after power after deflector is amplified and the deceleration, pass to again the track arm that is fixed on the steering swivel, the wheel flutter deflection that steering swivel and it are supported, thus changed travel direction.Mechanism is complicated, and cost is not complied with one's wishes, and arrangement optimization is poor.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of electri forklift steering hardware, solves existing steering structure complex structure, the problem that cost is high.
Technical scheme of the present invention is:
The electri forklift steering hardware, comprise bearing circle, the steering column that is arranged at the bearing circle below and is connected with bearing circle, the universal-joint that is arranged at the steering column below and is connected with steering column, the steer-drive that is connected with universal-joint, wheel flutter on the vehicle frame that is connected with steer-drive and setting and the vehicle frame, described steer-drive comprises driving device and the rolling disc that is connected driving device and is connected with universal-joint, described vehicle frame comprises vertical part and is connected in the horizontal component of vertical part bottom, the vehicle frame vertically top of part is captiveed joint with the steering handwheel end face, is provided with described wheel flutter on the vehicle frame horizontal component.
Described driving device is selected chain-wheel mechanism, gear drive or pulley transmission mechanism.
The below of described steering handwheel is connected with revolution and supports, and revolution is supported the below and is connected with stay bearing plate, and stay bearing plate is vertically captiveed joint on the top of part with described vehicle frame.
Described chain-wheel mechanism includes the sprocket wheel that is rotationally connected with universal-joint and is wound in chain on sprocket wheel and the steering handwheel, and the termination of chain is connected with chain adapter plate on being arranged at steering handwheel.
Advantage of the present invention:
(1), has strength structure and the gap is adjustable;
(2), under normal motoring condition, it is little that wheel flutter produces self-vibration;
(3), the motor coordination that produces of the present invention, can readjust the gap after the secondary wearing and tearing of sprocket wheel chain, make it to have suitable drive gap;
(4), adopt adjustable steering column, it turns to sensitivity, turning-circle diameter is little;
(5), chain-wheel mechanism just has good converter speed ratio and high rigidity, driving efficiency is high, arrangement convenience is easy to transmit the pilot control signal, sensitieness is good;
(6), that wheel flutter is passed to the recoil of steering handwheel is little, and transmits steering effort by the contact between chain-wheel mechanism and the steering handwheel, has larger intensity and resistance to abrasion preferably.
The present invention have low noise, easy and simple to handle, modern design, volume small and exquisite, turn to light.When the driver turns over an angle with steering handwheel, that wheel flutter will fixing angle of deflection.The driver need to be according to factors such as the variation of road surface camber, speed of a motor vehicle variations in the turning process, constantly adjust the angle of wheel flutter by rotating steering handwheel, keeps the driver and wishes the turning track that reaches.Turn to reliable, failure rate is low etc.Simultaneously its to control stability characteristic (quality) good, have higher task performance reliability, each block construction is compact, commonality is good, can carry out continuous stepless control and rotate, and offers control loop and mechanical dimensions and selects widely face.
