Abstract:
The present disclosure relates to a method of determining whether a frame (11) of a work machine (10) is approaching a tip over point. The frame (11) includes first and second support arrangements (20) each supporting a portion of the load of the frame (11) on a surface. A first load upon the first support arrangement is detected using first sensing means (34) and a second load upon the second support arrangement is detected using second sensing means. Signals are generated indicative of the first and second loads. The signals are communicated to a controller. The controller is configured to generate an alert based upon the first and second loads when the first and/or second load signals indicate that the orientation of the work machine is approaching a tip over point.
Abstract:
The invention concerns an inching and braking system for a hydraulically operated apparatus with a braking system (116) and a drive system (102), wherein the drive system (102) and the braking system (116) can be controlled by actuation of the inching and braking system in order to produce a braking effect. According to the invention, an inching valve arrangement (4) and a brake valve arrangement (2) are mechanically coupled to one another such that the apparatus can be controlled more sensitively during transition from inching to braking.
Abstract:
The present disclosure relates to a method and device for operating a powertrain of a motor vehicle, wherein the powertrain comprises an internal combustion engine, a transmission and a friction clutch arranged there between in order to control a power flow between the internal combustion engine and the transmission. The method comprises the steps of detecting clutch judder, analysing clutch judder, and determining a type of clutch judder. Based on determined type of clutch judder the method further comprises selecting a judder countermeasure from a number of predetermined judder countermeasures and executing selected judder countermeasure. The present disclosure has the effect that detected clutch judder can be taken care of in the currently most efficient way and that future clutch judder may be prevented.
Abstract:
An electric vehicle comprises an electrical system and a hydraulic system. The electrical system comprises an electric power supply and an electric motor-generator connected to the drive train of the vehicle. The hydraulic system includes a pump, and a hydraulic actuator. At least one of the electrical system and the hydraulic system includes energy recovery means arranged to convert kinetic energy from the drive train to electrical energy or to convert kinetic energy from the hydraulic actuator into hydraulic pressure respectively. The electrical and hydraulic systems are connected such that the recovered energy may be converted from electrical to hydraulic energy and/or vice versa. The hydraulic system may further include a hydraulic accumulator.
Abstract:
A tandem rear axle (28) suspended from a chassis frame (12) rearward of front steerable wheels (22, 24) has a first drive axle (30) with a driven wheel (32) on the right side and a driven wheel (34) on the left side and a second drive axle (36) rearward of the first drive axle and having a driven wheel (38) on the right side and a driven wheel (40) on the left side. A drivetrain couples a combustion engine (26) to the first drive axle for driving its driven wheels. A prime mover (52, 68, 70, 74) other than the combustion engine drives the driven wheels of the second drive axle.
