Abstract
A tracked vehicle steering system is described. Embodiments of the tracked vehicle system can include, but is not limited to, a tracked vehicle and a hydraulic system. The hydraulic system can be implemented to steer the tracked vehicle by applying a negative torque via one or more hydraulic pumps to components of the tracked vehicle.
Claims20
A tracked vehicle steering system comprising:
- a tracked vehicle having (i) an internal combustion engine, (ii) a driveshaft, (iii) a differential, (iv) a first axle, and (v) a second axle;
- a hydraulic system having (i) a valve body, (ii) a first hydraulic pump coupled to the first axle and fluidly connected to the valve body, (iii) a second hydraulic pump coupled to the second axle and fluidly connected to the valve body, and (iv) a fluid reservoir fluidly connected to the valve body;
- and
- the valve body being defined by:
- a first inlet port and a first outlet port for the first hydraulic pump;
- a second inlet port and a second outlet port for the second hydraulic pump;
- a plurality of reservoir ports for the reservoir;
- and
- a spool valve adapted to at least partially block one or more of the ports.

A tracked vehicle steering system comprising:
- a tracked vehicle having (i) an internal combustion engine, (ii) a driveshaft, (iii) an open differential, (iv) a first axle, (v) a second axle, and (vi) a steering mechanism;
- a hydraulic system having (i) a valve body operatively connected to the steering mechanism, (ii) a first hydraulic pump (a) coupled to the first axle, (b) adapted to apply a negative torque to the first axle, and (c) fluidly connected to the valve body, (iii) a second hydraulic pump (a) coupled to the second axle, (b) adapted to apply a negative torque to the second axle, and (c) fluidly connected to the valve body, and (iv) a fluid reservoir fluidly connected to the valve body;
- and
- the valve body consisting essentially of:
- a first port and a second port operatively connected to the first hydraulic pump;
- a third port and a fourth port operatively connected to the second hydraulic pump;
- a fifth port, a sixth port, a seventh port, and an eighth port operatively connected to the fluid reservoir;
- and
- a spool valve adapted to at least partially block one or more of the ports;
- wherein:
- (i) the first port, the fourth port, the fifth port, and the sixth port are arranged in a row in a first location on the valve body;
- and (ii) the second port, the third port, the sixth port, and the seventh port are arranged in a row in a second location opposite the first location on the valve body.
