Abstract
A throttle control mechanism for a surfacing machine, the control mechanism comprising a control member (310) arranged movable (M, D) in a support structure (320), wherein the control member (310) is arranged to be tensely attached to a throttle actuator (330) of the surfacing machine via a tensile engagement member (340), wherein the control member (310) is arranged to be held fixed in the support structure in at least a first throttle position (350), where the control member is arranged biased towards an idle throttle position (370) when released from the first throttle position (350), and wherein the first throttle position (350) and the idle throttle position (370) are configurable to provide an engine speed margin with respect to a clutch engagement engine speed range of the surfacing machine.
Claims21
A throttle control mechanism for a surfacing machine powered by a combustion engine and comprising a clutch mechanism,
- the control mechanism comprising a control member arranged movable in a support structure,
- wherein the control member is arranged to be tensely attached to a throttle actuator of the surfacing machine via a tensile engagement member,
- wherein the control member is arranged to be held fixed in the support structure in a first throttle position, where the control member is arranged biased towards an idle throttle position when released from the first throttle position, and
- wherein the first throttle position and the idle throttle position are configurable to provide an engine speed margin with respect to an undesired engine speed range of the surfacing machine.
A method for operating a throttle control mechanism to control a surfacing machine powered by a combustion engine and comprising a clutch mechanism, wherein the control mechanism comprises a control member arranged movable in a support structure, wherein the control member is arranged to be tensely attached to a throttle actuator of the surfacing machine via a tensile engagement member, wherein the control member is arranged to be held fixed in the support structure in at least a first throttle position, where the control member is arranged biased towards an idle throttle position when released from the at least first throttle position, and wherein the at least first throttle position and the idle throttle position are configurable to provide an engine speed margin with respect to an undesired engine speed range of the surfacing machine, the method comprising
- releasing the control member from a current throttle position, and
- moving the control member into a desired throttle position, whereby the control member is held fixed in the desired throttle position by the support structure.
