Up to10%cash back · Oct 08, 2020 · Steering tests showed a significant drop in system pressure fluctuation, the energy consumed is also reduced. Further, the analysis shows that the force arm difference is the main factor causing the pressure fluctuation, providing the theoretical and experimental basis for the design of a steering system of wheel loaders.

The traditional wheel loader is built without any axle suspension and experiences severe vibration. Three different layouts of hydropneumatic suspension, namely, unconnected strut (UCS), interconnected in roll plane (IC-R) and interconnected in roll and pitch plane (IC-RP), are installed on the wheel loader to improve ride comfort. This study mainly focuses on the damping effect …

Rockfall is one of the most serious geological hazards in mountain regions. During the rescue situations after rockfall, the wheel loader, a vital type of modern engineering mechanism, plays an important role in relieving the obstruction of the catastrophic site. Increasing the reliability of the wheel loader during the rescue situation is quite important.

on very small wheel loaders only one pump is used for steering and implements, and a separate pump is used for the brake charge and fan drive systems. On larger wheel loaders greater than 100 HP, typically two pumps are used; one to give priority flow to steering and then one to join the other pump for the implements as shown in this circuit.

The wheel loaders can be divided into power system, mechanical system, hydraulic system and control system. As an organic whole, whether the performance of the wheel loader is good or not is not only related to the performance of the mechanical parts of the working device, but also related to the performance of the hydraulic system and the control system.

steering wheels were blocked. On the steering wheel there was mounted a bar with the length value known. A radius of 280 mm from the centre of the steering wheel was chosen to mount the force transducer type S2 100N with a maximum load accepted of 100 N produced by the Hottinger manufacturer. The force transducer was pulled

The steering in a wheel loader is most commonly a hydraulic steering but not from this viewpoint part of the working hydraulic even if it is closely linked to it. The possibility to affect the steering comfort with the shift valve is not negligible. The shift valve has the possibility to in a system with hydraulic steering to let the hydraulic

other road vehicles: the wheel loader has a large pitch inertia compared to its mass, the axle loads vary considerably with loading condition, and the vehicle uses an articulated frame steering system rather than wheel steering. These issues must all be considered in the design process for a wheel loader suspension.

Estimation of the center of gravity (CG) is the basis for intelligent control of the front-and-rear-axis-independent electric driving wheel loaders (FREWLs). This paper presents a novel real-time method for estimating the CG of FREWLs, which is suitable for driving and spading conditions on bumpy roads. A FREWL dynamical model is proposed to set up the state-space model.
