Abstract

Electromechanical steering joint with tilting in two planes consists of a turning plate (1) with a pin (5), a steering frame (2), a control frame (3) and a tilting frame (4). The turntable plate (1) is connected to the front axle (20) by means of screw connections (18), and the tilting frame (4) is connected to the rear axle (21) by means of screw connections (19). The turntable (1) is rotatably connected to the steering frame (2) by means of a pin (5). This connection allows the two components to be tilted transversely to each other. Damping and springing of transverse tilting is ensured by a system of two spring-dampers (6) placed at one end on the pivots (7) of the turntable and at the other end in the rockers (8) of the repacking (9) connected to the steering frame (2). The central pin (10) is fixedly mounted in the steering frame (2), which is rotatably mounted in the control frame (3). Steering is provided by an electric motor with a gearbox (11) located in the control frame (3). The electric motor with a gearbox (11) rotates the control pin (10) with the help of a chain gear (12), resulting in mutual rotation of the controlled (2) and the control frame (3). The connection of the control frame (3) and the tilting frame (4) is realized by means of a pivot pin (13) firmly mounted in the tilting frame (4) and rotatably mounted in the control frame (3). This connection enables the longitudinal tilting of the two components towards each other. Damping and springing of longitudinal tilting is provided by a system of two spring-dampers (14) placed at one end on the consoles (15) of the control frame (3) and at the other end in the rockers (16) of the tilting frame (17) connected to the tilting frame (4).

Description

Oblasť technikyThe field of technology

Technické riešenie sa týka konštrukcie kĺbu na použitie v kĺbom riadených vozidlách. Kĺb sa vyznačuje tým, že zabezpečuje možnosť naklápania v dvoch smeroch (priečnom na smer jazdy a pozdĺžnom na smer jazdy) a otáčania tak, aby kĺbom spájané nápravy mohli meniť svoju vzájomnú polohu, a to pozdĺžne v smere jazdy a kolmo na smer jazdy pri jazde rovno a aj pri zatáčaní. Technické riešenie spadá do oblasti strojárstva, konkrétne do oblasti konštrukcie pozemných dopravných prostriedkov.The technical solution relates to the design of the joint for use in articulated vehicles. The joint is characterized by the fact that it provides the possibility of tilting in two directions (transverse to the direction of travel and longitudinal to the direction of travel) and turning so that the axles connected by the joint can change their relative position, namely longitudinally in the direction of travel and perpendicular to the direction of travel when driving straight and even when turning. The technical solution falls into the field of mechanical engineering, specifically in the field of construction of land vehicles.

Doterajší stav technikyCurrent state of the art

- Na použitie vozidiel v teréne, v lesoch, v horách a v ovocných sadoch sa v súčasnosti využívajú najmä štvorkolesové vozidlá s riadením prednej nápravy, výnimočne riadené kĺbom.- For the use of vehicles in the field, in forests, in the mountains and in orchards, four-wheeled vehicles with front axle steering, exceptionally steered by a joint, are currently used.

- V kĺbom riadených vozidlách sa na zmenu smeru jazdy spravidla využíva hydraulické riadenie kĺbu.- In articulated vehicles, hydraulic articulated steering is usually used to change the direction of travel.

- V kĺbom riadených vozidlách sa nepoužíva odpruženie jednotlivých častí kĺbu a v súčasnosti sa kĺby zhotovujú ako pevné, neodpružené a otočné iba okolo jednej alebo dvoch rovín alebo s odpružením, ale odpruženie je spravidla hydraulické.- Articulated vehicles do not use the suspension of the individual parts of the joint, and currently the joints are made as fixed, unsprung and rotatable only around one or two planes or with suspension, but the suspension is usually hydraulic.

Podstata technického riešeniaThe essence of the technical solution

Podstata technického riešenia vychádza z toho, že kĺb, ktorý riadi zatáčanie vozidla, je ovládaný elektromotorom s prevodovkou a pomocou reťazového prevodu otáča riadiacim čapom, čím dochádza k vzájomnému natáčaniu riadeného a riadiaceho rámu. Otočná doska je pomocou skrutkových spojov spojená s prednou nápravou a naklápací rám je spojený pomocou skrutkových spojov so zadnou nápravou. Otočná doska je s riadeným rámom otočne spojená pomocou čapu a toto spojenie umožňuje vzájomné priečne naklápanie týchto dvoch častí. Tlmenie a pruženie priečneho naklápania zabezpečuje sústava dvoch pružinových tlmičov. Spojenie riadiaceho rámu a naklápacieho rámu je realizované pomocou otočného čapu pevne uloženého v naklápacom ráme a otočne uloženého v riadiacom ráme a toto spojenie umožňuje vzájomné pozdĺžne naklápanie týchto dvoch častí, pričom tlmenie a pruženie pozdĺžneho naklápania zabezpečuje sústava dvoch pružinových tlmičov.The essence of the technical solution is based on the fact that the joint, which controls the turning of the vehicle, is controlled by an electric motor with a gearbox and, with the help of a chain gear, rotates the steering pin, which results in mutual rotation of the driven and steering frame. The turntable is bolted to the front axle and the tilting frame is bolted to the rear axle. The turntable is rotatably connected to the controlled frame by means of a pin, and this connection allows the two parts to be tilted transversely. Damping and suspension of transverse tilting is provided by a system of two spring shock absorbers. The connection of the control frame and the tilting frame is realized by means of a pivot pin fixedly placed in the tilting frame and rotatably placed in the control frame, and this connection enables the mutual longitudinal tilting of these two parts, while the damping and springing of the longitudinal tilting is provided by a system of two spring shock absorbers.
