Abstract
A stabilizer system includes a first object that moves relative to a second object and includes a first actuator coupled to a first wear pad. The first actuator drives the first wear pad to contact a first side of the second object to control motion of the first object relative to the second object. The first actuator operates in a first mode and in a second mode. While operating in the first mode, the first actuator applies a first force to the first wear pad to block the motion of first object relative to the second object. While the first actuator is operating in the second mode, the first actuator applies a second force, lower than the first force, to the first wear pad to enable the motion of the first object relative to the second object.
Claims19
A stabilizer system, comprising:
- a first object configured to move relative to a second object;
- a first actuator coupled to a first wear pad, the first actuator configured to drive the first wear pad to contact a first side of the second object to control motion of the first object relative to the second object;
- and
- a controller communicatively coupled to the first actuator, the controller comprising a processor and a memory device comprising instructions stored thereon that when executed by the processor are configured to cause the processor to:
- in a first mode apply a first force with the first actuator to substantially block the motion of the first object relative to the second object in response to receiving a first control signal indicative of terminating the motion of the first object relative to the second object;
- and
- in a second mode apply a second force lower than the first force with the first actuator to enable the motion of the first object relative to the second object in response to receiving a second control signal indicative of imitating the motion of the first object relative to the second object.
A stabilizer system, comprising:
- a first object configured to move relative to a second object;
- a first actuator coupled to a first wear pad, the first actuator configured to drive the first wear pad to contact a first side of the second object to control motion of the first object relative to the second object, the first actuator further configured to operate in a first mode and in a second mode, the first actuator configured to apply a first force to the first wear pad to block the motion of first object relative to the second object while the first actuator is operating in the first mode, and the first actuator configured to apply a second force, lower than the first force, to the first wear pad to enable the motion of the first object relative to the second object while the first actuator is operating in the second mode;
- and
- a second actuator coupled to a second wear pad, the second actuator configured to operate in the first mode and in the second mode, the second actuator configured to apply the first force to the second wear pad so as to block the motion of the first object relative to the second object while the first actuator and the second actuator are operating in the first mode, and the second actuator configured to apply the second force, lower than the first force, to the second wear pad to enable the motion of the first object relative to the second object while the first actuator and the second actuator are operating in the second mode.
A method to control a force applied by one or more actuators of a stabilizer system of a work vehicle, wherein the method comprises:
- instructing, via a controller, a valve assembly of the stabilizer system to apply a force, by the one or more actuators, to substantially block motion of a first object relative to a second object of a backhoe tool of the work vehicle in response to receiving a first control signal indicative of terminating the motion of the first object relative to the second object;
- instructing, via the controller, the valve assembly of the stabilizer system to reduce the force applied by the one or more actuators to enable the motion of the first object relative to the second object in response to receiving a second control signal indicative of imitating the motion of the first object relative to the second object;
- and
- actuating, via the controller, the first object to move along an actuation direction oriented along a length of the second object so as to extend or shorten a dig length of the backhoe tool in response to the second control signal.
A controller of a work vehicle, the controller communicatively coupled to one or more actuators and a sensor assembly of a stabilizer system, the controller comprising a processor and a memory device comprising instructions stored thereon that when executed by the processor are configured to cause the processor to:
- instruct a valve assembly of the stabilizer system to apply a force, by the one or more actuators, to substantially block motion of a first object relative to a second object of a backhoe tool of a work vehicle in response to receiving a first control signal indicative of terminating motion of the first object relative to the second object;
- and
- instruct the valve assembly of the stabilizer system to reduce the force applied by the one or more actuators to enable the motion of the first object relative to the second object in response to receiving a second control signal indicative of initiating the motion of the first object relative to the second object.
