Description

Electric drive system of remote control vehicle Technical field

The present invention relates to a hydroelectric drive system for a remote control vehicle, and particularly to a hydroelectric drive system for a remote control vehicle that can operate a vehicle at a standstill or walking and can be charged simultaneously while using a remote control signal.

Background technique

The biggest difference between a tracked vehicle and a wheeled vehicle is that because of the tracked design of the tracked vehicle, compared with a wheeled vehicle that uses wheels, the track has a larger area of contact with the ground and can overcome more severe terrain. Generally speaking, the tracked Vehicles are mostly special-purpose and heavy vehicles. For example, tanks, excavators, and bulldozers are all tracked vehicles. Such tracked vehicles usually have greater output power and more excellent off-road capabilities.

Most of the known model tracked vehicles use a motor as the main power source. The left track movement mechanism and the right track movement mechanism are independently driven by different motors. In order to maintain the model tracked vehicle implicitly maintained during forward or backward movement In a straight path, a specific motor (such as a stepper motor) or a powerful electronic control circuit is required to accurately control the synchronous rotation of the motors used to drive the left crawler movement mechanism and the right crawler movement mechanism, thereby ensuring that The model tracked vehicle can implicitly maintain a straight path when it is moving forward or backward, without generating a deflection or curvilinear motion path.

Limited by the storage capacity of the battery, the endurance of model tracked vehicles using motors as the main power source is usually inferior to that of model tracked vehicles using engines. Because the engine can only output the main power in a single direction of rotation, if the engine can generate electricity in combination The output will be able to simultaneously run the engine to generate electricity when the tracked vehicle is moving forward, backward, left and right, and the generated electricity can be stored for the walking of the tracked vehicle. Simultaneous power generation to supplement the power consumed by the crawler vehicle while walking should be an optimal solution.
