Embodiment Construction

[0013] Referring now to the accompanying drawings, and in particular to figure 1 , the figure shows a truck 100 with a chassis 120 on which a cement mixing bucket 110 is mounted for rotation. In accordance with the teachings of the present invention, the integrated hydraulic activation system tracks the mixing bowl 110 rotational speed and the number of revolutions made by the bowl.

[0014] figure 2 The vehicle hydraulic PTO system 44 and vehicle electrical control system 10 for monitoring and controlling the cement mixing drum 110 are shown. The hydraulic PTO system 44 rotates the cement mixing drum 110 using pressurized oil / hydraulic fluid provided by the pump 50 . Hydraulic fluid is selectively delivered through valve manifold 34 to hydraulic motor 48 which rotates bucket 110 . Valve manifold 34 allows pressurized hydraulic fluid to be delivered to hydraulic motor 48, hydraulic PTO system 44 as part of a circulating hydraulic flow circuit, and provides directional cont...

Abstract

For a cement mixer installed on a vehicle, a vehicle controller area network is modified to develop from engine speed, hydraulic power take-off system pressure and programmed data on power take-off pump capacity estimates of rotational speed and barrel rotational count. The network can also maintain a constant barrel rotational speed during transportation.

Description

technical field [0001] This invention relates to the control of hydraulic starting systems of motor vehicles, and more particularly to the application of such control to hydraulic starting systems of on-board cement mixing drums. Background technique [0002] Modern trucks are often equipped with power start operation (PTO). PTOs are used in auxiliary systems such as hoisting, hoisting and pumping. The PTO may be powered directly or indirectly by the vehicle engine. An indirect energy supply system such as a hydraulic system is one of the most common. Power to the auxiliary hydraulic system is converted from engine output via an engine-driven hydraulic pump. A hydraulic pump draws working fluid from a tank and provides the fluid to a hydraulic valve manifold that diverts the working fluid to cylinders or impellers for moving the target load. [0003] Original vehicle manufacturers have long supplied their vehicles with universal hydraulic pumps that are adapted to suppor...
