Definitions
- the present invention relates to a traveling device and a power limiting mechanism used for a model or the like.
- a traveling device that transmits torque from a power source to a wheel via a power transmission mechanism such as a worm or worm wheel
- the wheel is used to prevent damage to the gear of the power transmission mechanism when a large external force acts on the wheel.
- the provision of a power limiting mechanism for limiting the torque transmitted from the power transmission to the power transmission system has been conventionally performed (see Japanese Patent No. 2834468). Disclosure of the invention
- the present invention provides a traveling device and a power limiting mechanism capable of limiting the torque input from the wheels to the power transmission mechanism even when the installation space of the power transmission mechanism has no margin. With the goal.

Therefore, even if there is not enough space in the arrangement space of the power transmission mechanism, if there is room around the wheels, the power transmission mechanism can be protected against torque from the wheel side by the power limiting mechanism. Also, the power limiting mechanism There is also an advantage that the power limiting mechanism can be attached by simply replacing the wheels with an existing traveling device that does not have a motor.
- the traveling device of the present invention is provided with a pair of drive sources that independently drive a pair of left and right wheels, respectively, and branches between each drive source and each wheel to the left and right from each drive source toward each wheel.
- each wheel limits the torque transmitted between the wheel and the axle. It is provided with a power limiting mechanism.

If a power limiting mechanism is further provided for each power transmission mechanism, The installation space for the power transmission mechanism is bulky and the traveling equipment cannot be enlarged.
- the provision of the power limiting mechanism on the wheels eliminates the need to provide the same type of limiting mechanism in the power transmission mechanism, so that the power transmission mechanism can be made compact and the traveling device can be made sufficiently small.

- the torque is transmitted between the rotor and the disk wheel by maintaining the engagement between the pair of engagement portions by the spring means.
- the reaction force acting between the mating portions exceeds the pressing force by the spring means, and the mating portion becomes radial.
- the rotor is displaced to remove the balance, and the rotor and the wheel rotate relatively. This limits the torque transmitted between the wheels and the axle.
- the disk wheel is provided with an accommodation hole for accommodating the rotor, and the outer periphery of the accommodation hole is recessed radially outward of the disk wheel.
- An axle connection portion connected to the axle; and an arm portion extending from the axle connection portion in a circumferential direction of the rotor and functioning as the spring means.
- the joint portion of the rotor may be provided at a tip end of the arm portion so as to protrude outward in a radial direction of the rotor.
- the power transmission structure is compact by arranging the mating portion between the outer periphery of the rotor accommodated in the disk wheel and the peripheral surface of the accommodation hole. Can be suppressed. Furthermore, in the case where the arm portion and the mating portion of the rotor are provided as a pair symmetrically in the left-right direction, the power limiting action can be equally generated regardless of the rotation direction of the wheel.
- the present invention can also be grasped as a power limiting mechanism applicable to the traveling device described above. That is, the power limiting mechanism of the present invention is a power limiting mechanism that is provided in a wheel and limits a torque transmitted between the wheel and the axle, and is fixed to the axle and integrated with the axle.
- the at least one force of the rotor is displaceable in the radial direction, and is pressed toward the mating portion by a spring means.
- the disc wheel is provided with a receiving hole for receiving the port, and at least one hole is formed on a peripheral surface of the receiving hole so as to be recessed radially outward of the disk wheel.
- the rotor is provided with an axle connection portion connected to the axle, and an arm portion extending from the axle connection portion in a circumferential direction of the rotor and functioning as the spring means.
- the joint portion of the mouth may be provided at a tip portion of the arm portion so as to protrude outward in a radial direction of the rotor.
- the arm portion and the mating portion of the rotor may be provided as a pair symmetrically.
