The signal can be filtered, using a digital notch filter, to generate a filtered signal, and an actuator of the work element can be controlled based on the filtered signal.

Hydraulic hose clamp
11592122 · 2023-02-28 · ·

A hose clamp for supporting a hose with respect to a machine. The hose clamp may include a deformable clamping element comprising a section of material at least partially surrounding an opening. The opening extends through a thickness of the clamping element and is configured to receive the hose. The hose clamp additionally comprises a support element configured to secure the clamping element to the machine. The support element is further configured to compress the clamping element along a direction of the thickness of the clamping element, thereby deforming the clamping element and causing the clamping element to constrict around the hose.

Working machine
11572675 · 2023-02-07 · ·

A working machine comprises an operation member for operating a hydraulic device via a control valve. An oscillation calculator acquires a specific value corresponding to a feature representing oscillation of the operation member when the feature appears in variation of an control signal output according to an operation amount of the operation member within one of a sequence of predetermined periods, and calculates an evaluation value representing a degree of oscillation of the operation member by adding up the specific value or values obtained within one or more of the predetermined periods. A control signal generator generates a control signal for controlling the control valve based on the operation signal. The control signal generator decreases a value of the control signal per a unit value of the operation signal as the evaluation value gradually increases with the elapse of one or more of the sequence of the predetermined periods.

TILT BUCKET
20220349148 · 2022-11-03 ·

A bucket assembly for use with a piece of construction equipment, the bucket assembly including a bucket including a base wall with a leading edge, where the bucket defines a bucket width, and a bucket frame pivotably coupled to the bucket and configured to be mounted to the piece of construction equipment, where the bucket frame defines a pivot axis about which the bucket pivots relative to the bucket frame over a pre-determined range of motion, where the pivot axis is parallel to the base wall of the bucket and perpendicular to the leading edge of the bucket, and where the pivot axis is centered along the bucket width.

HVAC AIR RETRIEVAL SYSTEM FOR WORK MACHINE

A work machine, such as a skid steer loader or a compact track loader, includes an air intake assembly for a heating, ventilation, and air conditioning (HVAC) unit. A conduit integrated into a structure supporting a roof over an operator cab accepts air and water from the atmosphere through an air inlet proximate the roof. A debris outlet downstream in the conduit allows gravity to return the water to the environment. Between the air inlet and the debris outlet, an orifice in the conduit connects to an air duct through which the air may be diverted by suction from the HVAC unit. An air filter at the end of the air duct removes remaining particulates from the air prior to conditioning by the HVAC unit. Sizing the cross-sectional areas of the air path to exceed a cross-sectional area of an inlet to the air filter and providing a substantially straight air path avoids resistance to air flow, resulting in efficient intake of cleaner air.

HOSE SUPPORT STRUCTURE, LINK FOR WORK VEHICLE, AND WORK VEHICLE

A hose support structure includes a first round bar and a second round bar provided on a mounting surface of a first plate and extending in a first direction. A first restraint and a second restraint face the mounting surface in a second direction and are provided between the first round bar and the second round bar in a third direction. The first restraint extends from a first proximal end toward a first distal end in a fourth direction, and the second restraint extends in a fifth direction opposite to the fourth direction from a second proximal end connected to the first proximal end. A third restraint is provided opposite to the second restraint with respect to the first restraint in the first direction. At least a part of the second restraint is separated from the mounting surface by a second distance shorter than the first distance in the second direction.
