What is the Principle of a Pull-Back Car?
1 Answers
The principle of a pull-back car is that the axle transmits force to the pull-back gear to perform work, and the gear drives the pull-back gear. Design of the pull-back car: Through the axle transmitting force to the pull-back gear to perform work, the gear-driven pull-back gear structure converts the kinetic energy from hand motion into potential energy. The pull-back car is designed for rear-wheel forward drive, and the pull-back gear is designed for backward rotation to store energy. Due to the fixed direction of the axle, as long as the energy stored in the pull-back gear is sufficient or the static friction between the car and the ground is small enough, the pull-back car can move forward by the energy output from the pull-back gear, which acts as its heart. Difference between an inertia car and a pull-back car: An inertia car can move both forward and backward because it has a flywheel device, while a pull-back car can only move in a fixed, single direction.
