Power distribution mechanism for the transmission of forest tracked and wheeled vehicles

Abstract

The article schematically considers a proposal for development and application of a controlled power distribution mechanism for machines involved in timber industry and agriculture. Use of the mechanism will increase energy efficiency of skidder and forwarder on tractor chassis, improve steering quality of tracked vehicles and improve controllability of wheeled vehicles. For articulated vehicles, use of a controlled power distribution mechanism is expected to reduce stresses on swing mechanism. The article presents analysis results of literary sources on problem of using controlled power distribution mechanisms in transmissions of tracked and wheeled vehicles. Advantages of using such mechanisms in transmissions of tractors and forest vehicles on their chassis are shown. References are given to publications containing descriptions of mechanisms that are similar in characteristics to the developed one and known methods for determining main parameters of power distribution mechanisms, approaches to kinematic, force analysis and energy balance construction of such mechanisms. Kinematic diagram of a new controlled mechanism of power distribution is considered, main parameters, control technologies, and areas of its application are determined. Links between the project and currently developed capabilities of Russian production are outlined. Development prospects of technology for controlling distribution of power in transmissions of tracked and wheeled vehicles in the field of transport engineering are indicated. A reference is given to the research complex created and used at the Peter the Great St. Petersburg Polytechnic University, as allowing to conduct comprehensive tests of experimental models of transmissions of transport and traction vehicles.

Design and analysis of electric power-assisted steering in vehicles for mountain forests

“…3 Forestry tractors also implement the principle of power distribution. 1 The benefits of this approach include improved vehicle safety. The advantages of assisted steering are that it makes it easier to use during parking, long turns, and other manoeuvres that require significant effort on the driver's part.…”

“…Road transportation is the most widely used mode of freightage in the Russian Federation. 1 Half of the cargo transported is classified as dangerous goods with the most adverse operating conditions for the machinery. 1 In the Far East wood industry, it is difficult to access quality commercial forests, most of which are left on mountainous slopes.…”

“…A magasabb hozzáadott érték biztosítása a jövedelmezőség javításának kulcsa (Dieste, et al, 2019), amely számos részterületen keresztül biztosítható. A kereskedelmi tevékenység modernizálása (Pinto, et al, 2022) (Barriault, et al, 2017), a termőhelyek alapanyagtermelési szempontokat figyelembe vevő kialakítása (Vaca, et al, 2022), a regionális faipari klaszterek kialakítása (Polyanin, et al, 2020) az energiafelhasználás optimalizálása (Dobretsov, et al, 2020), az innovatív projektek aktívabb finanszírozása (Golovina & Dykusova, 2020), a faipari üzemszervezés és logisztika modernizációja (Wieruszewski, et al, 2020) (Trojanowska, et al, 2016) (Koppelhuber, et al, 2016) egyaránt hatékonyságjavulást ígér. Versenyképességi és technológiai problémák egyébként nemcsak a második és a harmadik (Vrabcová, et al, 2019) világban lehetnek jelen, tapasztalhatunk ilyet a fejlett országokban (Lüthi, et al, 2019) (Kay, 2017) (Derikvand, et al, 2017) (Coombs & Forster, 2017) (Adamowicz & Noga, 2017)…”

Computational approach to estimation the transverse Stability of multi-section chassis of extreme cross-country vehicles

“…The principles of building advanced transmissions for two-link machines (see, for example, publications [13,14,15,16] are supposed to be extended to a multi-section chassis. It is expedient to carry out the control of the turn with a significant mass of the machine in a combined way -due to the mutual turn of the sections and the change in the traction forces along the sides [17,18,19,20,21,22,23]. To analyze the operation of the transmission, models similar to those described in the article [24] can be used.…”
