Some embodiments of the disclosure provide a brake mechanism, a power platform and a karting. The brake mechanism includes a brake assembly. The brake assembly is configured to be mounted on a vehicle frame, the brake assembly includes a brake pad, a position of the brake pad is adjustably configured, such that the brake pad has a first position and a second position. Herein, when the brake pad is located at the first position, the brake pad is configured to be in contact with a tire, and when the brake pad is located at the second position, the brake pad is separated from the tire.

The purpose of the present invention is to provide a safe device with which, by forcibly braking the rotation of a grapple by means of an external force, it is possible even for an unskilled operator to bring the rotation to a halt and further to prevent accidents due to such rotation. Another purpose of the present invention is to provide such a device at lower cost. According to the present invention, a grapple has a lower frame that has claws for gripping timber and an upper frame that rotatably holds the lower frame, and is provided with a rotation braking means that applies a brake on the rotation of the lower frame.

A rotation braking device includes a clutch mechanism disposed between an inner member and an outer member. The clutch mechanism includes an electromagnetic actuator which controls relative rotation of the cage such that, due to the relative rotation, engaging elements are moved between an engaged position and a neutral position. An armature is rotationally fixed relative to the cage, and can be directly magnetically attracted to an electromagnet which is rotationally fixed relative a housing that houses the clutch mechanism. The outer member is directly supported in a radial direction by the housing and engages the housing so as to limit relative rotation relative to each other.

A personal mobility vehicle, such as a scooter, includes at least one battery and motor for powering at least one driven wheel. The vehicle also includes a braking assembly configured to isolate the motor from the at least one driven wheel such that power is terminated from the motor to the at least one wheel in response to a user engaging a braking assembly of the vehicle. The vehicle can include a switch or position sensor that interacts with the braking assembly to initiate the isolation of the motor from the at least one driven wheel and the switch or position sensor preferably is inaccessible to the foot of the user.
