Summary:

Wheel Loaders are heavy equipment machines which are used in construction fields. Most of the wheel loaders are articulated vehicles. The main structure of a Wheel Loaders has a front and a rear frame, connected through a two pin joints (1) for articulation. The wheel loaders have two axles viz front and rear axles carrying the Front and Rear frame of machine. Front bogie consists of Frame, Bucket, Boom, Linkage and cylinders whereas rear bogie consists of the rear frame, power train components like Engine, Transmission, hydraulic systems, Operator Cab with controls for the machine operation.The front axle carrying front frame is fixed and articulates 40° clockwise and anticlockwise about rear frame. However, to reduce the spillage of material carried in bucket while travelling in uneven terrains, the rear axles (instead of front axle) are designed to oscillate along the roll direction of vehicle movement. The rear axle of the machine is connected to rear frame with bearing hub called Axle oscillation hub (2) having separate shaft arrangement with TRB (expand TRB) (3). When machine operates in uneven terrain, the oscillating rear axle hits the rear frame structure which induces an impact load on vehicle structure. Mass and speed of the vehicles plays a critical role in loader stability and safety. Apart from these, the impact force caused due to the rear axle hitting to vehicle frame influences the durability of the structural components.This paper explains the study done on establishing the relationship between the machine operating mass, vehicle speed and axle hitting loads on wheel loaders operation in uneven terrains. The study also focuses on determining the steps for selection of both structural and stopper components based on prediction of impact loads induced in wheel loaders during rear axle oscillation
