Abstract: The invention relates to a control device for controlling machines, especially hydraulic machines, by hand or foot. The inventive device comprises an actuating element (1), especially a pedal or a control lever, which can be moved in several directions. The aim of the invention is to feel a resisting force when the actuating element (1) is displaced or adjusted, whereby said force is on the scale of hydraulic forces having a direct effect. The actuating element (1) engages with a transmitter device (3) which is not hydraulic or is hydraulically decoupled from the hydraulic system. A damping device (6) engages with the actuating element (1). Said damping device defies the movement in at least one direction of motion pertaining to the actuating element (1) by means of a fluid that is moved by the actuating element (1).

Abstract: A control lever for a work vehicle having a work implement is provided with a shaft that operates a control linkage. The shaft and control linkage control two functions of the work implement by manipulating two hydraulic control valves. The shaft can be moved in two orthogonal directions or arcs. To prevent cross talk between the control functions the control lever is prevented from twisting by a stub shaft that is received in an elongated slot. The side walls of the elongated slot restrain the twisting movement of the control lever. The elongated slot is provided with a U-shaped slider made of an anti-friction material such as slippery urethane plastic. The U-shaped slider has legs that conform to the side walls of the elongated slot. That portion of the stub shaft located in the elongated slot has a cylindrical configuration.

Abstract: A pilot valve control for the drive motors of an excavator utilizes four pilot valves, each of which has a linear actuable plunger. A control body having a cam type member is mounted on a universal swiveling connection so that in a centered position none of the plungers are moved to actuate the respective valves, but upon tilting of the control body the plungers are actuated. A motion alarm actuator is connected to the control body and is associated with a normally closed switch so that in a centered position of the control body the normally closed switch is held open, but when the control body moves to any one of its positions actuating a pilot valve, the switch, which forms an alarm switch, moves to its normally closed position.

Abstract: This invention relates to an outdoor equipment unit such as a walk-behind utility loader. The loader has a tracked traction system in which endless tracks are entrained around a rear drive support member and a front support member. The front support member is spring biased forwardly, but can move rearwardly against the spring bias to allow debris that is caught between the front support member to clear itself to help prevent the track from detracking. A single control handle proximate to a fixed grab bar assembly can be rotated and/or twisted to control the traction system. Return to neutral systems ensure that the control handle will return to a centered, neutral position upon release of the control handle by the operator.

In general, the single lever control assembly is a type of modified universal joint whose movement is limited by a projection.

Abstract: A locking lever is enabled to lock a drive control system of a working implement in an undrivable state, even if it does not reach a locking stroke end. The locking lever is extended into a state to obstruct the passage into the passageway to a driver's seat thereby to switch a control selector lever of the working implement drive control system into a controllable position through a mechanical linkage. When the driver gets off from the driver's seat, the locking lever is returned from the passage obstructing position to a retracted position thereby to switch the control selector lever to an uncontrollable position through a the mechanical linkage. These operations are switched midway of the rocking stroke of the locking lever by bringing the control selector lever to the stroke end so that the locking lever is made idle to the stroke end of the retracted position while retaining the control selector lever in the switched state.

Abstract: A drive linkage that is used for controlling valves for the drive motors of an implement or machine, such as an excavator, has a pair of links that can be loaded in tension and compression by manually moving operating levers. The links in turn actuate a cam that tilts a swiveling disk to operate a pilot valve assembly normally used for a joystick control. The links are connected so that the pilot valve can selectively operate motors for driving opposite tracks on sides of the implement in either forward and reverse direction, and wherein motors for both sides can be operated in a forward direction and in a rearward direction. Additionally, each of the drive motors can be controlled so the motor for one side drives in forward direction and simultaneously the motor for the other side drives in reverse direction. A control disk for moving the plungers is operated through a cam plate that is in turn moved by moving the links.

Because of its setting contour, the actuating lever 43 can be used for both the right hand and the left hand lower steering arm.

The actuation travel of the control lever is limited by a stop point that is defined by a stop and the control lever has means to generate a restoration force. The stop has an elastic component, as a result of which an at least slight deflection of the control lever beyond the stop point is possible. The elastic component of the stop is realized so that in the event of a deflection beyond the stop point, the restoration force, as a function of the deflection, increases to a greater extent than in the event of a deflection of the control lever between a neutral position and the stop point.

Abstract: A dual function throttle control system is disclosed for earthmoving machines. The throttle control system includes a hand lever that is electrically connected to a proportional directional hydraulic valve. Rotation of the hand lever controls actuation of an engine speed actuator and thus the speed of the engine. A foot pedal is connected through a three position spring-centered hydraulic valve to the engine speed actuator. The direction of flow of hydraulic fluid through the three position spring-centered hydraulic valve is controlled by the position of the hand lever. When the hand lever is set at the lowest speed setting, rotation of the foot pedal in a first direction increases the engine speed. When the control lever is set at the highest speed setting, rotation of the foot pedal in the first direction decreases the speed of the engine. Thus, the foot pedal operates both as a decelerator or an accelerator depending on the position of the hand lever.
