Abstract
Tracked vehicles include a track assembly, a powertrain assembly to power the track assembly, and a steering assembly configured to provide a torque to the track assembly. A steering motor is operably coupled to the powertrain assembly to effectuate a steering of the vehicle. A backup steering assembly is configured to provide backup steering capability to the tracked vehicle. The tracked vehicle also includes a plurality of steering modes, as well as a plurality of suspension components configured to increase rider comfort.
Claims18
A tracked vehicle, comprising:
- a first track assembly and a second track assembly;
- a powertrain configured to provide rotational power to the first track assembly and the second track assembly;
- a steering system operably coupled to the first track assembly and the second track assembly, the steering system comprising:
- a steering motor;
- a geartrain operably coupled between the steering motor and the powertrain;
- a steering control unit configured to receive a steering input signal;
- a generator operably coupled to the powertrain, the generator configured to provide power to the steering motor;
- and
- the steering control unit configured to provide a steering output signal to the steering motor, the steering output signal being one of a positive torque command and a negative torque command.
A vehicle, comprising:
- a first track assembly;
- a second track assembly;
- a frame supported by the first track assembly and the second track assembly;
- a powertrain supported by the frame, the powertrain including a prime mover, a transmission operably coupled to the prime mover, a drive member, and a propshaft extending from the transmission to the drive member;
- the drive member comprising:
- a drive housing;
- an input configured to receive the propshaft;
- a plurality of outputs including a first output and a second output, the first output rotatably coupled to the first track assembly and the second output rotatably coupled to the second track assembly;
- and
- a steering assembly comprising:
- a steering motor;
- a geartrain operably coupled between the steering motor and the plurality of outputs;
- and
- the steering motor is coupled to the drive housing.
