Abstract
An active steering device of a vehicle comprises a supporting framework (1), a transverse front bracket (2) and a transverse back bracket (3) are connected with the supporting bracket through a revolving supporting bear (4); steering mechanisms are arranged outside the front bracket and the back bracket; both ends are respectively symmetrically provided with running wheels (5) driven by a running motor (7). The steering mechanism comprises fixed guiding wheels (6) arranged on both sides of the running wheels, a rotating disk (15) arranged on a base, connecting rod mechanisms (13 and 14) hinged with the rotating disk, and rotating arms (11 and 12) hinged with both ends of a connecting rod, wherein, the rotating disk can rotate along an axle center (16) under the driving of a steering motor (9); one end of each rotating arm is arranged on a fixing shaft (17), and the other end is provided with a moveable guiding wheel (10). The active steering device causes the vehicle to have steering function, and the vehicle can freely automatically run on a straight road and a bend road; moreover, the active steering device has simple structure, reliable running, and the small space occupation.
Description
Technical field
The utility model belongs to the logistics equipment field of mechanical technique, is specifically related to a kind of steering hardware of materials handling vehicle.
Background technology
In the automatic material flow system, existing rail materials handling vehicle is most of self not to be possessed and turns to and the turnout driving functions, can only move on rectilinear orbit, can not be on bend turning driving automatically.In the practical application, have some can be on the track on band turnout the vehicle of turning driving, do not have the function of turning to but its turning is a vehicle self, but after relying on external force that track is pulled track switch, wheel is along the track walking of artificial guiding.This dependence changes track routes and realizes that the mode of turning has the following disadvantages at least: the one, and the track structure design is complicated, the 2nd, need artificial or control system is pulled the running route that control vehicle is come on the turnout continually, influence work efficiency, also increase the automatically controlled process, can not satisfy the demand of modern efficient logistics system.But also have some producers to use the small rail car of active steerings, but it turns to and needs to rely on the complicated air-actuator of a cover to finish, need on vehicle, increase compressed air unit, power is required high, complex structure and huge.
Summary of the invention
The purpose of this utility model provides a kind of vehicle self that makes to possess the function of turning to for the deficiency that solves above-mentioned prior art existence just, can on straight way and bend, travel automatically freely, and vehicle active steering device simple in structure, reliable, that take up room little.
The purpose of this utility model is achieved by the following technical solution.
A kind of vehicle active steering device, comprise a support frame, be connected and installed with horizontal front frame and after poppet by pivoting support bearing on support frame, in the outside of front frame and after poppet steering hardware be installed, two ends are symmetrically installed with the running wheel that is driven by movable motor respectively; Described steering hardware comprises the stator wheel that is installed on the running wheel both sides, be installed on the rotating disk that drives and can rotate by steer motor on the pedestal along the axle center, be hinged on the connecting rod mechanism on the rotating disk, be hinged on the pivoted arm at connecting rod two ends, one end of pivoted arm is installed on the anchor shaft, and the other end is equipped with the activity-oriented wheel.
When the utility model passed through bend when vehicle, the steer motor action drove rotating disk and affects connecting rod mechanism and pivoted arm action, takes turns outwards swing thereby drive activity-oriented.After the swing of activity-oriented wheel puts in place, cooperate, clamp the guide plate on the track, make vehicle under the guiding of track adjusting wheel, realize turning to stator wheel.Because front frame and after poppet are articulated and connected by pivoting support bearing and support frame, make the mutual independence that turns to of front and back running wheel, thereby can obtain less turn radius, make turn inside diameter nimbly and freely.Self have driving power in addition, make the utility model self possess steering capability, do not need to rely on manual change's track and realize turning to.
The utility model is simple in structure, and control is convenient, reliable operation.Use the utility model, can simplify the design of track greatly.
Further set forth content of the present utility model below in conjunction with Figure of description.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the scheme drawing that the utility model travels in orbit;
Fig. 3 is the A-A cross sectional drawing of track.
The specific embodiment
As shown in Figure 1, the utility model comprises a support frame 1, on support frame, be connected and installed with horizontal front frame 2 and after poppet 3 by pivoting support bearing 4, the outside at front frame 2 and after poppet 3 is equipped with steering hardware, two ends are symmetrically installed with the running wheel 5 that is driven by movable motor 7 respectively, and running wheel 5 is installed in the wheel mount 18; Described steering hardware comprises the stator wheel 6 that is installed on the running wheel both sides, be installed on the pedestal 8 by steer motor 9 drive and can be along the axle center 16 rotating disks 15 that rotate, be hinged on the connecting rod mechanism 13,14 on the rotating disk, be hinged on the pivoted arm 11,12 at connecting rod two ends, one end of pivoted arm is installed on the anchor shaft 17, and the other end is equipped with activity-oriented wheel 10.Stator wheel is installed in the both sides of wheel mount 18.Two movable motors 7 are fixed on the inboard of wheel mount.Can design different delivery vehicles, as roller conveyor, chain-linked conveyer etc. according to the difference that is handled upside down object above the support frame 1.
As shown in Figure 2, the utility model is placed on the track 19, track is formed by walking stay bearing plate 20 with at the upright circular-arc guide plate 21 in the stay bearing plate outside as shown in Figure 3.
Working process is as follows: vehicle when needs turn to, starts 16 rotations along the axle center of steer motor 9 rotating disks 15 in the process of walking, affects pivoted arm 11,12, connecting rod 13,14, thereby drives the outwards swing of activity-oriented wheel 10 on the steering hardware.After 10 swings of activity-oriented wheel put in place, two stator wheels 6 on wheel mount 18 cooperated, and clamp the guide plate 21 on the track, and front frame 2 or after poppet 3 are travelled forward under the guiding of three track adjusting wheels.When car body moved to the bend place, front frame 2 or after poppet 3 rotated around circular-arc guide plate under the guiding of circular-arc guide plate 21, by them and support frame 1 pivotally attached pivoting support bearing 4, affected support frame 1 realization handling maneuver.In order to make car body can pass through bend glibly, the running wheel 5 of two individual drive will carry out speeds match control according to predefined program.
