Abstract
The utility model relates to a novel four-wheel steering system controlled by four servos. The novel four-wheel steering system controlled by the four servos is mainly composed of four wheels, four direct current deceleration drive motors, four steering engines, four servo supports, four motor supports and corresponding control circuit boards. The novel four-wheel steering system controlled by the four servos is characterized in that 9s12 series singlechips are adopted by the system for centralized control and dispersed modular design, every wheel is in fixed connection with one servo support used for the steering engine and one motor support, the servo support for the steering engine and the motor support are adjacent to the wheel, every servo which is connected with one wheel is responsible for steering control, and every wheel is supplied by one drive motor which is connected with the wheel with power. The four steering servos are connected with the singlechips, steering of the steering engines is controlled by the singlechips so that independent steering of the four wheels is achieved. Furthermore, the four wheels can all rotate toward the left and the right at an angle of 0-90 degrees, so that the functions of the whole bodywork such as rotating and changing directions at the same site, moving obliquely, turning at a minimum radius and traveling transversely are achieved.
Description
Technical field
The invention belongs to intelligent vehicle four-wheel steering technical field, relate to a kind of Electromechanical Control technology, particularly relate to a kind of intelligent apparatus of the novel four-wheel steering system by four steering wheels control.
Background technology
At present, steering technique generally all be that two-wheeled turns to, the shortcoming such as two-wheeled turns to have and turns to the space that needs large, and is convenient not and flexible.And the four-wheel steering technology is also among further developing, existing four-wheel steering system generally all is the handling maneuver of controlling trailing wheel by being installed in electronically controlled motors actuate actuators in the rear axle housing, the generation of its control command is derived from the electronic control unit ECU of sensor and complexity, and the control of front-wheel is still by the mechanical linkage maneuverability pattern, the four-wheel steering technology just can not be given full play to it and has flexibly stable characteristic like this, and existing four-wheel steering technology is applied on the vehicle fully.
Summary of the invention
The utility model is a kind of novel four-wheel steering system by the control of four steering wheels.System is mainly by 4 wheels, 4 direct current deceleration motors, and 4 steering engines and corresponding control circuit board form; It is characterized in that: system adopts 9s12 series monolithic centralized control and dispersed modules design, each wheel is captiveed joint with electric machine support with the steering wheel support with that steering engine that is adjacent, each wheel is responsible for control by a coupled steering wheel and is turned to, and each wheel is by a coupled driving motor supplies power; Four steering engines are connected with micro controller system, by turning to of Single-chip Controlling steering engine, thereby realize the independent steering of four wheels, and make four wheel left/right rotations to the rotations that all can reach 0-90 degree, realize that the original place rotation of whole vehicle body is turned around, diagonal, minimum radius is turned and the function of cross running.Simultaneity factor arranges that original place rotation is turned around, diagonal, minimum radius is turned and four kinds of coomand modes of cross running namely: under vehicle body keeping parallelism handling maneuver state, rear-axle steering is identical with front-wheel steering, can realize fast stable forward parallel, thereby the movement of realization fast and stable; When rear-axle steering was opposite with front-wheel steering, the turn radius in the time of can reducing low speed driving largely was convenient to narrow road surface and is carried out U-shaped turning; When four wheels turn to certain angle separately, the contact point on four wheels and ground when same concentric circles, be implemented in narrow road surface progressive type and turn, thereby realize that spot turn turns to; When four wheel steerings are mutually 90 when spending in movable body, can realize cross running.
Technique effect of the present utility model is: the utility model system not only has the collaborative function that turns to of front and back wheel, also contained the in the market technical functionality of different phase, middle phase place and synchronous four-wheel steering, four-wheel steering technology of the present utility model well can be applied on the vehicle simultaneously, be difficult for the predicament used at vehicle thereby solve other four-wheel steering technology; Four-wheel steering system of the present utility model is applied to can increase on the vehicle body accuracy of vehicle mobile and the alerting ability that turns to and information control, thereby the spot turn of realizing vehicle body turns to, diagonal and the function such as walk crosswise, and the turn radius can reduce low vehicle speeds time the, steering stability when improving high vehicle speeds, solve the vehicle technical barrier such as difficult that turns around in narrow location.

Fig. 2 is the principle of work diagram of circuit of the four-wheel steering system of the utility model four steering wheels control.
Among the figure: 1. wheel, 2. steering engine 3. drive motor 4. steering wheel supports 5. electric machine supports.
The specific embodiment
Below be the preferred embodiments of the utility model patent, therefore do not limit protection domain of the present utility model.
See accompanying drawing 1, the utility model mainly is comprised of wheel 1, steering engine 2, drive motor 3, steering wheel support 4 and electric machine support 5.It is characterized in that: those steering engine 2 usefulness steering wheel supports 4 that each wheel 1 is adjacent are captiveed joint with electric machine support 5, and each wheel 1 has the 2 responsible controls of a steering engine to turn to, and each wheel 1 has a drive motor 3 that power is provided; Four steering engines 2 are connected with singlechip controller, by turning to of Single-chip Controlling steering engine 2, thereby realize the independent steering of four wheels 1, make four wheels 1 and all can reach the rotations of 0-90 degree left and to the right, realize that the original place rotation of whole vehicle body is turned around, diagonal, minimum radius is turned and the function of cross running.Simultaneity factor arranges that original place rotation is turned around, diagonal, minimum radius is turned and four kinds of coomand modes of cross running namely: under vehicle body keeping parallelism handling maneuver state, rear-axle steering is identical with front-wheel steering, can realize stablizing forward parallel fast; When rear-axle steering is opposite with front-wheel steering, the turn radius in the time of can reducing low speed driving largely; When four wheels 1 turn to certain angle separately, the contact point on four wheels 1 and ground when same concentric circles, be implemented in narrow road surface and carry out zero type and turn, thereby realize that spot turn turns to; Be mutually 90 when spending when four wheels 1 turn on movable body, can realize cross running.
