mechanical benefit assessment in 4x4 articulated tractors
ADVANCE, ADVANCE or GAIN MECHANIC
• It is the percentage difference between the traction of the front tire with respect to the rear ground-based equipment in 4x4. There are two types of improvements: kinematic which is the rotation difference of the front and rear axles, and the actual static feed, measured as traction on the ground. The advance is important so that the front wheel has auxiliary function on the rear-wheel drive, must be positive between 0% and 5% for a better optimal traction performance is between 1.2% to 1.8%.
BENEFITS
• The greatest benefits of the positive development within the ideal range are: reducing rear wheel slippage, less need weight to work, less tire wear, lower fuel consumption, increased operator comfort, and increased system life mechanic.
• This software has been designed for use in tractors Articulated tires with full wheel drive for better adjustment of machine operating conditions, improve traction relationship identifying the advance, informing the advance by the front wheel relative to the rear, the leading cause of galloping, lose yield and high slip is advance out of the optimal range, and when negative causes the tractor to the rear exhaust sides requires a correction to the pilot system and or manually.
PROCEDURE
• To advance the evaluation of the equipment must be adjusted with the pressures of the tires according to the machine manufacturer's manual and or tires. Place the machine on firm and level ground without incidence of shadow on the basis of tires for better identification of the soil in the images, if required drive the machine so that pictures have similar lighting. In the case of very dark soils it is recommended to select the base tire with white chalk for better identification of the tire contact with the ground threshold. The effective reading is valid for the conditions of weight and tire pressures.
• photographs obeying the order should be taken: FRONT LEFT REAR LEFT FRONT RIGHT AND RIGHT REAR. Images can be taken directly in the application with the device camera and later charged in the same order and or directly through the Kinetic Pleadings application. For a better analysis we must take the pictures always frontally to the tire rim caring for the environment take the top of the tire and a solo track. Remembering that tilted photos and / or framework nonstandard hinder a correct analysis.
