Sensor mounting system for road milling machine
First Claim
1. A road milling machine, comprising:
- a machine frame carried by a plurality of ground engaging members;
a rotor supported by the machine frame and oriented perpendicularly relative to a longitudinal centerline of the road milling machine for treating a ground surface;
first and second side plates arranged at opposite side ends of the rotor;
a sensor mounting system including;
a first mounting member attached to a first machine component and supporting a first portion of a first position sensor;
a second mounting member attached to a second machine component having a pivotable attachment to the machine frame;
an extension member having a first end attached to the second mounting member and a second end including an attachment flange; and
a unitary ski member having a first end attached to a second portion of the first position sensor and a second end pivotably attached to the attachment flange, wherein the unitary ski member includes a ground engaging surface that is positioned inboard relative to the first and second side plates, and the ground engaging surface has a pivot movement compensation curve; and
a controller configured for determining a milling depth of the rotor from measurements obtained by the first position sensor.

Abstract
A road milling machine includes a sensor mounting system having a first mounting member, which is attached to a first machine component and supports a portion of a position sensor, and a second mounting member attached to a second machine component having a pivotable attachment to a machine frame. An extension member has a first end attached to the second mounting member and a second end including an attachment flange. A unitary ski member has a first end attached to another portion of the position sensor and a second end pivotably attached to the attachment flange. The unitary ski member includes a ground engaging surface that is positioned inboard relative to first and second side plates, which flank a rotor, and has a pivot movement compensation curve. A controller is configured for determining a milling depth of the rotor from measurements obtained by the position sensor.

16. A method for measuring a milling depth of a road milling machine having a sensor mounting system, the sensor mounting system including:
- a first mounting member attached to a first machine component of the road milling machine and supporting a first portion of a first position sensor;
a second mounting member attached to a second machine component having a pivotable attachment to a machine frame;
an extension member having a first end attached to the second mounting member and a second end including an attachment flange; and
a unitary ski member having a first end attached to a second portion of the first position sensor at a first ski attachment location and a second end pivotably attached to the attachment flange at a second ski attachment location, wherein the unitary ski member includes a ground engaging surface positioned inboard relative to first and second side plates that flank a rotor of the road milling machine, the method comprising steps of;moving the road milling machine, via a plurality of ground engaging members, in a forward travel direction along a ground surface; lowering the rotor supported on the machine frame to a predetermined milling depth to treat the ground surface; contacting the ground surface to be treated with the ground engaging surface of the unitary ski member at a first position along a pivot movement compensation curve of the ground engaging surface, wherein the first position is a predetermined distance from the first ski attachment location; determining, via a controller, a first milling depth of the rotor from measurements obtained by the first position sensor responsive to contacting the ground surface at the first position; pivoting the second ski attachment location relative to the machine frame; contacting the ground surface to be treated with the ground engaging surface of the unitary ski member at a second position along the pivot movement compensation curve, wherein the second position is also the predetermined distance from the first ski attachment location; and determining, via the controller, a second milling depth of the rotor from measurements obtained by the first position sensor responsive to contacting the ground surface at the second position. - View Dependent Claims (17, 18, 19, 20)
