Abstract
A towed cart and implement having a brake assembly enabled for independent application of the cart brake assembly without application of the brakes of prime mover in a burst application of the brake assembly for a predetermined duration. A brake control system includes a display which indicates the capacity of the brake assembly for burst application based on a temperature of a brake assembly component. The temperature may be measured or estimated based on duration and timing of burst brake applications.
Claims20
A brake system for a cart towed by a prime mover comprising:
- a friction brake assembly having a brake rotor and calipers;
- and
- a brake control system having;
- a programmable processor;
- an input device;
- and
- a display, wherein the control system actuates burst application of the brake assembly upon activation of the input device, wherein burst application of the brake assembly comprises repeated short-duration actuation of the brake assembly, and further indicates on the display a current capacity of the brake assembly for burst application of the brake assembly and whether or not there is capacity in the brake assembly for any burst application of the brake assembly.
A method of controlling a brake assembly of a towed cart, the cart having a frame, an axle with wheels upon which the frame is supported for movement over a ground surface, a brake assembly on the axle and brake control system having an input device and a display, the method comprising the steps of:
- activating the input device;
- actuating burst application of the brake assembly upon activation of the input device, wherein burst application of the brake assembly comprises repeated short-duration actuation of the brake assembly;
- and
- indicating on the display a current capacity of the brake assembly for burst application of the brake assembly and whether or not there is capacity in the brake assembly for any burst application of the brake assembly.
A machine comprising:
- a commodity cart having a frame and a cart axle with wheels upon which the frame is supported for movement over a ground surface;
- an implement configured to be coupled to the cart for movement together with the cart, the implement having a plurality of ground engaging tools movable between a lowered position engaging the ground and raised position above the ground;
- a friction brake assembly on the cart axle;
- and
- a brake control system having a programmable processor, an input device and a display, the control system actuating burst application of the brake assembly upon activation of the input device, wherein burst application of the brake assembly comprises repeated short-duration actuation of the brake assembly, and indicating on the display a current capacity of the brake assembly for burst application of the brake assembly and whether or not there is capacity in the brake assembly for any burst application of the brake assembly.
