Description
Technical field
The utility model relates to telecar, intelligent vehicle, intelligent distant control vehicle, a kind of wheel steering driving mechanism of program control car.
Background technology
Existing telecar, intelligent vehicle, the wheel steering technology of program control car is that front-wheel can left-right rotation certain angle, realize turning to of car, but the left and right turn corner of wheel is all less than 60 degree.Such structure limits the mobility of vehicle, is therefore necessary completely to be improved prior art.
Summary of the invention
The purpose of this utility model, is the steering mechanism providing a kind of steering angle larger, makes left and right vehicle wheel steering angle be more than or equal to 90 degree.
The technical solution of the utility model is as follows:
Wheel or wheel power system are connected with wheel connector, it is characterized in that: some wheel connectors are connected on support, some steering wheels are connected on support, some strong points are connected on support, wheel connector turning center is connected with rocking arm, rocking arm force node is connected with connector, form and exert a force node for end points with wheel connector turning center and rocking arm, rocking arm and connector and support are the parallelogram sturcutre on limit, the strong point is connected with strong point rocking arm, strong point rocking arm force node is connected with connector, steering wheel is connected with steering wheel rocking arm, steering wheel rocking arm force node is connected with connector, form with steering wheel spindle central and the strong point and steering wheel rocking arm force node and strong point rocking arm force node for end points, steering wheel rocking arm and strong point rocking arm and connector and support and steering wheel are combined as the parallelogram sturcutre on limit.Two parallelogram sturcutres all share connector, so when a parallelogram sturcutre motion deformation, another parallelogram sturcutre is also along with motion deformation.Form some parallelogram and work in coordination with linkage structure.Realize under servo driving, some steering angle of wheels remain consistent, make wheel maximum rotation angle be more than or equal to 180 degree.
The utility model of such realization, its beneficial effect is: make vehicle mobility rise to a new high degree.Realize the mobility that existing vehicle cannot realize.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further, but the content of the utility model is not limited thereto.
In Fig. 1, revolver connector (21) and the right connector (22) and steering wheel (14) and the strong point (8) of taking turns are connected on support (20), rocking arm one (1) is connected on revolver connector turning center (6), rocking arm two (2) is connected to rightly takes turns on connector turning center (7), strong point rocking arm (3) is connected on the strong point (8), steering wheel rocking arm (4) is connected in the steering wheel rotating shaft (9) of steering wheel (14), connector (5) and rocking arm one exert a force node (10), rocking arm two exerts a force node (11), strong point rocking arm force node (12), 4 nodes such as steering wheel rocking arm force node (13) connect.Form the mechanism being combined collaborative interlock by two parallelogram, realize driving wheel steering.
In Fig. 2, wheel steering driving mechanism is decomposed into, revolver, rightly takes turns, revolver connector (21), rightly take turns connector (22), steering wheel (14), the strong point (8), support (20), rocking arm one (1); rocking arm two (2), strong point rocking arm (3), steering wheel rocking arm (4), connector (5).Wherein, revolver connector (21) there is revolver turning center (6), right take turns connector (22) has rightly take turns turning center (7); rocking arm one (1) has rocking arm one to exert a force node (10); rocking arm two (2) to have rocking arm two to exert a force node (11); strong point rocking arm (3) to have strong point rocking arm to exert a force node (12), steering wheel rocking arm (4) has steering wheel rocking arm to exert a force node (13), steering wheel (14) has steering wheel rotating shaft (9).
In Fig. 3, revolver connector turning center (6) and right connector turning center (7) and rocking arm one exert a force four end points such as node (11) and rocking arm one (1) and the rocking arm two (2) and connector (5) and support (20) of node (10) and rocking arm two that exert a force of taking turns form parallelogram one (15).Exert a force four end points such as node (13) and strong point rocking arm (3) and steering wheel rocking arm (4) and connector (5) and support (20) and steering wheel (14) of the strong point (8) and strong point rocking arm force node (12) and steering wheel rotating shaft (9) and steering wheel rocking arm forms parallelogram two (16).In motion process, when parallelogram one (15) interior angle angle is close or when equaling 0 degree or 180 degree, parallelogram two (16) interior angle angle is close or equal 90 degree, otherwise in like manner.Therefore, when the parallel hold facility of parallelogram one (15) is least stable, the parallel hold facility of parallelogram two (16) is the most stable, 2 parallelogram complementations, the parallelogram sturcutre realizing wherein any one cooperative motion has good parallel stability when any form.Realize under servo driving, some steering angle of wheels remain consistent, make wheel maximum rotation angle be more than or equal to 180 degree.
In Fig. 4, in motion process, steering wheel corner is 90, and parallelogram two (16) 2 interior angle angles equal 0 degree, and when 2 interior angle angles equal 180 degree, parallelogram one (15) 4 interior angle equals 90 degree.Wheel mediates, without turning to.
In Fig. 5, in motion process, steering wheel rotates some angles, and parallelogram one (15) is motion deformation along with the motion deformation of parallelogram two (16), drives vehicle wheel rotation to corresponding angle.
In Fig. 6, in motion process, servo driving wheel steering, steering wheel turns to 180 degree, and parallelogram one (15) 2 interior angle angle equals 0 degree, when 2 interior angle angles equal 180 degree, parallelogram two (16) 4 interior angles equal 90 degree, and wheel turns left to 90 degree.Otherwise wheel turns right to 90 degree in like manner.
