1. Horáček, Radim. Design zemědělského traktoru .

Degree: 2015, Brno University of Technology

Předmětem této diplomové práce je design zemědělského traktoru zaměřený na inovativní přístup k návrhu s technickými, estetickými, ergonomickými a ekologic- kými požadavky. Cílem designu je navržení svébytného a tvarově charakteristického stroje nesvázaného konvenčním řešením. Na traktor je pohlíženo z pohledu vztahu farma–zemědělský stroj, alternativního přístupu k pohonu a šetrnosti jeho provozu ke svému okolí.; The main subject of this master‘s thesis is an innovative approach to design of an ag- ricultural tractor with technical, esthetic, ergonomic and economic demands. The aim is to create a distinctive design and shape of tractor unbound from conventional solutions. The concept takes account of the farm–machine relationship, the alterna- tive powertrain, and friendliness to the environment. Advisors/Committee Members: Křenek, Ladislav (advisor).

Subjects/Keywords: Zemědělský traktor; těžký kolový traktor; tahač; alternativní pohon; průtoková baterie; trakční elektromotory; An agricultural tractor; heavy wheeled tractor; tractor; alternative powertrain; flow battery; traction electric motors

2. Krátký, Martin. Podvozky traktorů .

Degree: 2012, Brno University of Technology

Bakalářská práce se zabývá v současnosti používanými podvozky kolových a pásových traktorů. V první části je proveden přehled a stručný popis jednotlivých konstrukčních částí. Druhá a třetí část je zaměřena na řízení kolových a pásových traktorů. Jsou zde podrobněji popsány jednotlivé druhy řízení a uveden princip činnosti. Nejvíce prostoru je věnováno hydrostatickému řízení, které je nejrozšířenější. V závěru je shrnut současný stav v konstrukci podvozků traktorů, používaná řešení, popsány nové moderní systémy a nastíněn předpokládaný trend vývoje.; This bachelor thesis deals with the currently used chassis of wheeled and tracked tractors. In the first part is an overview and a short description of individual components. The second and third parts are focused on steering of wheeled and tracked tractors. There are in detail described different types of steering and is given a principle of operation. Most of space is devoted to hydrostatic steering which is the most widespread. In the end is summarized a present situation in designing of tractor chassis. There are mentioned used solutions and are described new modern systems and is estimated a supposed trend of development. Advisors/Committee Members: Kaplan, Zdeněk (advisor).

3. Marcelino João Knob. ESTUDO DE TRAFEGABILIDADE APLICADO A VEÍCULOS DE RODA EM TRANSPORTE E TRAÇÃO.

Degree: 2010, Universidade Federal de Santa Maria

The ability of vehicles to traverse soft soils is an important aspect of their performance. The geological, climate and topography diversity originated, in Rio Grande do Sul, extensive areas of hydromorphic clay soils, as example, Planssoils and Gleissoils. When saturated of water, these soft soils present low loads support, difficult agricultural machinery work and limit the traverse of military wheeled vehicles. The aim of this study was to determine the limit of soil conditions for trafficability of military 6 x 6 wheeled trucks (Cascavel and Urutu), determine the ground pressure and predict the mobility condition from soil cone index (SCI) and vehicle characteristics. This study also proposed to evaluate the performance of a four wheel drive tractor in drawbar pull test and trafficability performance, to correlate the reduced tire inflation pressure and vehicle loading effect on slipping, drawbar pull, fuel consumption and mobility under different soil moisture conditions. It was found that the Cascavel military truck had a minimal ground pressure of 357 kPa and it needed SCI of 402 kPa in the critical layer for a single pass. The Urutu truck had a ground pressure of 401 kPa and required at least 431 kPa in SCI for one-way pass. The NATO Reference Mobility Model (NRMM) and Mean Maximum Pressure (MPP) predicting model underestimate the soil cone index required for these military vehicles to traverse soft-soils, however, MMP was more appropriate to predict the correct SIC for the tested vehicles. For the tractor experiment it was found that tire inflation pressure changed the ground pressure and the vehicle loading didnt change the ground surface pressure. The greatest drawbar pull were obtained at low tractor speed, reduced inflation pressure and high loading level, operating on hard ground. The lowest specific fuel consumption was obtained on hard ground, empty weight, low tire pressure and operating in high speed gear. The increase of soil moisture decreased the dynamic traction coefficient from 0.57 to 0.31 and the traction efficiency decrease from 50 to 37%. Reduced inflation tire pressure had positive effects on tractor mobility in waterlogged soils, reducing slipping and increasing traverse speed. Using height loading level had negative effect on wet soils because it require more engine power and increase the fuel consumption.

A habilidade de um veículo se locomover em solos com baixa capacidade de carga é um aspecto importante em seu desempenho. A diversidade geológica, climática e de relevo originou, no Rio Grande do Sul, extensas áreas de solos Hidromórficos argilosos, entre eles, os Planossolos e os Gleissolos. Quando saturados, estes solos apresentam baixa capacidade de suporte de carga, dificultando o trabalho de máquinas agrícolas e o deslocamento de veículos militares de roda. O presente trabalho teve por objetivo determinar as condições de solo limite para a trafegabilidade de veículos militares de roda com tração 6 x 6 (Cascavel e Urutu), determinar a pressão de contato pneu-solo e predizer a…
