The utility model is different from the traditional mechanical sensors and hydraulic sensors, and realizes electronic steering. The utility model has the advantages of energy and labor saving, flexible and easy operation, and high performance to price ratio compared with the same products aboard.
Description
The utility model relates to sensor field, particularly a kind of electrical steering sensor that is used for engineering truck.
Along with the attention of the whole world to environmental protection, the trend to the elec. vehicle development has appearred in engineering truck.The traditional engineering truck of China mostly adopts mechanical type and fluid pressure type steering hardware, is mechanical type as what use on the early stage fork truck, and what have fork lift truck applications now is fluid pressure type mostly.Fluid pressure type generally is that the driven by motor oil pump drives wheel flutter by hydraulic efficiency pressure system, but hydraulic oil pump needs running always, and charged all the time, it is bigger to consume energy.
In the last few years along with Power Electronic Technique and development of computer application technology, occur full electronic abroad and turned to the trend that substitutes conventional steering, but it is very expensive that development is used for electrical steering sensor manufacturing complexity, the import price of engineering truck, particularly maintenance difficult.
The utility model purpose is:
A kind of electrical steering sensor that is used for engineering truck is proposed, performance, power saving, cost-cutting, ratio of performance to price height, maintenance that this sensor can not only improve vehicle are easy, engineering truck is turned to more flexibly, fast, steadily, can be used on the reach formula storage battery forktruck or on other any one engineering truck.The technical solution of the utility model is:
A kind of engineering truck electrical steering sensor, comprise sleeve (1), cover (2), magnet ring (3), copper sheathing (4), bearing carrier ring (5), pad (6), spring collar (7), key (8), friction ring (9), spring (10), packing ring (11), nut (12), steering shaft (13), Hall element (14), it is characterized in that:
The core of electrical steering sensor is a columniform metal steering shaft (13), packing cover (2) in the periphery, lower end of steering shaft, at the other magnet ring (3) of installing of the wall of cover (2), two groups of Hall elements (14) are installed in the surface of sleeve (1) and have two groups of Hall component output near magnet ring (3);
On cover (2), copper sheathing (4) is arranged, bearing carrier ring (5) is being packed in the periphery of copper sheathing (4), pad (6) and spring collar (7) are installed above the bearing carrier ring (5), at the top installation ring of sleeve (1) friction ring (9), in the peripheral mounting spring (10) of friction ring (9) and connect packing ring (11) and nut (12) around steering shaft (13);
Magnet ring (3) segmentation in the sensor has opposed polarity magnetic, whole circle is by K the N utmost point and K S extremely alternate the composition (K is an integer), rotation magnet ring (3) along with bearing circle in rotation also rotates thereupon, the last N utmost point of magnet ring (3) and S utmost point magnetic turn over the sensitive surface of Hall element (14), produce corresponding electric pulse, reach measurement steering wheel angle;
Described two groups of Hall elements (14) in the installation site on the sensor circumference are: when one of them element alignment N utmost point center, it is 360 degree/4K to the angle in the center of circle that another element leaves arbitrary N utmost point center, error ± 360 degree/8K, thus its output the Direction of Reaction dish direction of rotating accurately guaranteed.
Described magnet ring (3) and Hall element (14) can be installed on the engineering truck electrical steering sensor of Any shape and structure.The beneficial effects of the utility model are:
Be different from traditional mechanical type and fluid pressure type, realized turning to electronization.
1. power saving, storage battery power supply.When bearing circle is moving, the motor startup of just switching on.Motionless
The time motor do not power energy-conservation the economize on electricity more than 50%.Compare electric liquid with electric-liquid type
Formula one starts, and the steer motor of drive is switched on all the time.
Flexible operation, easily, reduce chaufeur labour intensity.
3. follow external like product ratio, ratio of performance to price height.
The drawing explanation:
Fig. 1 is the constructional drawing of engineering truck electrical steering sensor.
Fig. 2 is the application scheme drawing of engineering truck electrical steering sensor on fork truck.
The utility model is described in further detail below in conjunction with embodiment.
Fig. 1 is the constructional drawing of engineering truck electrical steering sensor.Engineering truck electrical steering sensor 16 mainly is made up of sleeve 1, cover 2, magnet ring 3, copper sheathing 4, bearing carrier ring 5, pad 6, spring collar 7, key 8, friction ring 9, spring 10, packing ring 11, nut 12, steering shaft 13, Hall element 14 in Fig. 1.
Described two groups of four Hall elements 14 installation sites on sensor 16 circumference are to guarantee that two Hall elements of every group are bordering on 55 degree to the angle in the center of circle, thereby guarantee the direction that its output can the accurate response axle be rotated.
Fig. 2 is the application scheme drawing of engineering truck electrical steering sensor on fork truck.Among Fig. 2 bearing circle 15 be installed in sensor 16 above, when bearing circle 15 circled, each Hall element 14 in the sensor 16 can externally be exported 64 electric pulse, these electric pulse are sent into steering controller 17.
