  • Brake-actuating steering and braking control system for tracked vehicles
    Patent number: 6527070
    Abstract: A brake-actuating steering and braking control system for a tracked vehicle is provided with a braking control subsystem, a steering control subsystem, and right and left side brake-actuating subsystems. The braking control subsystem includes a brake pedal and is connected to brake mechanisms of each brake-actuating subsystem. A user may depress the brake pedal to apply a braking force to right and left side track assemblies of the tracked vehicle via the brake mechanisms to thereby slow or stop the tracked vehicle. The steering control subsystem includes a steering wheel and is connected to each of the brake mechanisms. The user may rotationally displace the steering wheel, which applies a braking force to the track assembly corresponding to the direction of rotational displacement of the steering wheel via the corresponding brake mechanism to thereby turn the tracked vehicle.
