Abstract

This utility model discloses a four-wheel steering system for RC model cars, relating to the technical field of RC model cars. It includes a chassis frame and front and rear wheel frames mounted at both ends. Front wheels are symmetrically mounted on both sides of the front wheel frame, and rear wheels are symmetrically mounted on both sides of the rear wheel frame. A front steering mechanism is mounted on the front wheel frame, with its two ends connected to the two front wheels respectively, enabling it to steer both front wheels. A rear steering mechanism is mounted on the rear wheel frame, with its two ends connected to the two rear wheels respectively, enabling it to steer both rear wheels. This four-wheel steering system for RC model cars, through its precise mechanical structure and servo control, effectively overcomes the shortcomings of traditional two-wheel steering RC model cars in terms of flexibility, stability, and ability to navigate complex terrain. It significantly improves the vehicle's handling performance, driving pleasure, and scene adaptability, making it particularly suitable for racing, off-road, and climbing scenarios where high handling performance is required.
