Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing.

[0025] The working principle of the present invention is: the use of the ball-limited repetitive folding and unlocking mechanism, and the conversion of the axial and circumferential motions of the sequentially moving hub through the ball-limiting device. When the sequential motion hub moves axially, it moves in a plane with its hinged axial push rod, and then drives the radial push rod fixed on the wheel rim to move radially, thereby adjusting the radial size of the wheel; sequential motion type When the hub rotates in the circumferential direction, the hub, axle, spokes, and rim form an integrated wheel structure, and the wheel is in an overall locked state. The motor can drive the wheel to rotate to realize its driving function.

[0026] Such as Figure 1-3 As shown, the ball-limiting type repeated folding and unlocking wheel mechanism of the present invention is compose...

Abstract

The invention discloses a ball spacing type repeated folding-unfolding wheel locking and unlocking mechanism. A ball spacing device is used for realizing the axial and circumferential motion conversion of a hub, i.e. when the hub moves along the axial direction in sequential motion, an axial push rod hinged with the hub carries out planar motion so as to drive a radial push rod fixedly connected to a hub sloping block to move along the radial direction, thereby regulating the radial size of a wheel; when the hub rotates along the circumferential direction in the sequential motion, the hub, a wheel axle, spokes and a wheel rim of the ball spacing type repeated folding-unfolding wheel locking and unlocking mechanism are formed into an integral wheel structure; the wheel is under the locking state; and the wheel can be driven to rotate so as to realize the driving function of the wheel. According to the ball spacing type repeated folding-unfolding wheel locking and unlocking mechanism disclosed by the invention, the radial size of the wheel can be effectively regulated according to different terrain conditions, the defect that the traditional moving obstacle-crossing probe vehicle has a poor adaptive capacity on the non-structural terrain can be overcome, and the terrain adaptability of the wheel is effectively improved.

Description

technical field [0001] The invention relates to a mechanism for improving the obstacle-surmounting performance of the whole vehicle by adjusting the radial dimension of the wheel, in particular to a ball-limited repetitive folding and unlocking wheel mechanism. Background technique [0002] Complex terrain mobile exploration vehicles are widely used in the fields of planetary exploration, military reconnaissance, and disaster search and rescue. Most of the operating environments are complex and unstructured terrains. In order to meet the performance requirements of high mobility, strong environmental awareness and quick response of mobile exploration vehicles, the wheels are the executive components of the mobile system of the exploration vehicle. greater impact. At present, although the wheels used by mobile exploration vehicles in complex terrain have strong driving performance and a certain ability to overcome obstacles, they have poor adaptability to complex and varied ...
