Abstract
A construction machine is provided. The construction machine includes a chassis and a ground engaging member (such as a wheel or a track) operable to support and move the chassis over ground. The construction machine further includes a work implement (such as a bucket) coupled to the chassis; a cab mounted on said chassis and having a user seat, and a first controller (such as a joystick) accessible to a user seated in the user seat. The joystick controls at least one of moving the work machine over ground and movement of the bucket. The joystick has a first actuator (such as a trigger button) that is operable to selectively engage ride control functionality.
Claims21
A construction machine comprising:
- a chassis;
- a ground engaging member operable to support and move the chassis over ground;
- a work implement coupled to said chassis;
- a cab mounted on said chassis and having a user seat;
- a first controller accessible to a user seated in the user seat, the first controller operable to control at least one of operation of the ground engaging member to move the construction machine over ground and operation of the work implement to provide movement of the work implement relative to the chassis, the first controller having a first actuator;
- and
- a second actuator operable to render the first actuator operable to place a fluid accumulator in fluid communication with the work implement to dampen the transfer of forces from the work implement to the user seat for a ride control functionality.
A construction machine comprising:
- a chassis;
- a ground engaging member operable to support and move the chassis over ground;
- a work implement coupled to said chassis;
- a fluid accumulator;
- a cab mounted on said chassis and having a user seat;
- a first controller accessible to a user seated in the user seat, the first controller including a first actuator, the first controller operable to control operation of the ground engaging member to move the work machine over ground;
- and
- a second actuator separate from the first controller, the second actuator operable to render the first actuator operable to selectively engage ride control functionality by placing the fluid accumulator in fluid communication with the work implement.
A method of selectively engaging ride control on a work machine, the work machine including a chassis and a work implement coupled to the chassis, the method including:
- receiving an input from a first button on a joystick control,
- receiving an input from a second button separate from the joystick control;
- and
- selectively engaging ride control functionality by hydraulically coupling a fluid accumulator to the work implement based, at least partially, on the received input from the first button and the second button.
