Description
Technical field
The present invention relates to car wheel structure, specially a kind of adjustable ratcheting mechanism of radius.
Background technique
With the development of science and technology with the raising of human living standard, people to the performance requirement of means of transport increasingly
It is high.On the one hand, when ratcheting mechanism is in flat ground motion, it is desirable that it is walked with good dynamic characteristics without fluctuating, efficiency
The advantages that high；On the other hand, when ratcheting mechanism is in non-flat forms ground motion, its smooth running is not required nothing more than, without larger shock,
But also there is certain obstacle detouring ability.
The axis of common ratcheting mechanism is fixedly mounted at the core wheel of wheel, and traveling not only can be with road at non-flat forms ground
The variation generation of condition is jolted, while being felt with rising and falling to feel and hit；Adjustable eccentric away from ratcheting mechanism, can be adjusted according to road conditions
The distance between nodal axisn and core wheel, but this mechanism is realized by changing the distance between line shaft and core wheel mostly
(distance is bigger, and obstacle detouring ability is stronger), there is no the radiuses for changing wheel body.
Summary of the invention
In consideration of it, the mechanism is automatic by intelligent control technology the invention proposes a kind of radius adjustable ratcheting mechanism
The radius for adjusting wheel, to adapt to different complicated landforms, while increasing the stationarity and obstacle climbing ability of mechanism.
It can be realized the adjustable ratcheting mechanism of radius of above-mentioned function, technical solution includes wheel, except that institute
Stating wheel includes multiple spokes with certain rim width, and multiple spokes divide 3 or more spokes of left and right side arrangement and each side
Circumference uniform distribution is simultaneously in identical radial location；It further include that radius adjusts component and motor drive component, the motor driven
Component be included in wheel center setting and by wheel carrier install Dual-output shaft motor, the Dual-output shaft motor it is left and right defeated
Drive bevel gear is installed on shaft；The radius adjusts component and includes screw rod and nut corresponding to the setting of each spoke and lead
Rail and slide, the guide rail are radially set on wheel carrier, and the spoke is installed on corresponding guide rail by corresponding slide, described
Screw rod is arranged radially, and the nut is combined on corresponding screw rod and is installed on corresponding spoke, the slave mantle tooth of screw rod inner end
Wheel engages corresponding drive bevel gear.
To make to run smoothly, the spoke dislocation of left and right side is opposite, there is the intersection of overlapping between the wheel rim for the spoke that misplaces.
In conventional design, the spoke design is 8, and every side is 4 spokes.
Beneficial effects of the present invention：
1, the adjustable ratcheting mechanism of radius of the present invention drives spoke radially to move back and forth by screw nut driven pair, thus
Achieve the purpose that adjust wheel body radius not only reduces wheel and be moved through so that wheel can adapt to different complicated landforms
Fluctuating sense and shock sense in journey, and also improve the obstacle climbing ability of wheel.
2, the present invention uses screw nut driven pair, ensure that the self-lock ability in transmission process.

Specific embodiment
Illustrated embodiment is described further technical solution of the present invention with reference to the accompanying drawing.
The adjustable ratcheting mechanism of radius of the present invention, technical solution include the wheel being arranged based on wheel carrier 2, radius adjusting group
Part and motor drive component.
The wheel includes each four spokes 1 of left and right side, four 1 circumference uniform distributions of spoke setting of each side, the spoke
1 includes fan-shaped disc and arc wheel rim, and the wheel rim has one fixed width and horizontal to the other side, and the spoke 1 of left and right side exists together
In in identical radial location and 45 ° of dislocation is opposite, there is the intersection of overlapping (to guarantee wheels travel between the wheel rim for the spoke 1 that misplaces
Stability and stationarity in the process), i.e. the head of the both ends (circumferencial direction) of the spoke 1 of the side spoke 1 adjacent with the other side,
Be overlapped between tail end (circumferencial direction), be 0 distance between the wheel rim end face of overlapping, the width of wheel be left and right rim width it
With as shown in Figure 1, Figure 2, Figure 3 shows.
The wheel carrier 2 is set to the center of wheel, for 45 ° of left and right cross of dislocation, the position difference of left and right cross
Corresponding to the wheel rim of left and right spoke 1, the center of each cross offers motor output shaft perforating, as shown in Figure 3.
The motor drive component includes Dual-output shaft motor 3 and Bevel Gear Transmission pair, and the Bevel Gear Transmission pair includes
Left and right drive bevel gear 4 and left and right each four driven wheel of differential 9, the Dual-output shaft motor 3 are pacified by electric machine support 10
Loaded between left and right cross, the left and right output shaft of Dual-output shaft motor 3 passes through the motor output shaft of left and right cross respectively
Perforating stretches out in corresponding cross and outside 1 disc of spoke for corresponding to side, and each drive bevel gear 4 is mounted on corresponding
On 3 output shaft of Dual-output shaft motor, as shown in Figure 1, Figure 2, Figure 3, Figure 4.
It includes the screw rod 5 and nut 6 and guide rail 7 and slide 8 corresponding to the setting of each spoke 1 that the radius, which adjusts component,
The screw rod 5 and nut 6 are set to outside the disc of corresponding spoke 1, and the guide rail 7 (sliding pin) and slide 8 (sliding block) are set to and correspond to
In the disc of spoke 1, specifically：The guide rail 7 is arranged radially, and the inner end of guide rail 7 is mounted on corresponding cross, guide rail 7
