The present utility model relates to the field of transporting, and more particularly to trailers. The claimed utility model provides a solution to the technical problem of the poor manoeuvrability of existing trailers and road trains comprising trailers, caused by their large dimensions, as well as the problem of significant difficulties when loading cargo from the side of a trailer, perpendicular to its direction of travel. The technical result of the claimed utility model is that of increasing the manoeuvrability of trailers and road trains comprising trailers by reducing the dimensions of a trailer while preserving the usable area of the cargo bed, and also that of allowing the loading of cargo from the side of the trailer, perpendicular to its direction of travel. The technical result is achieved in that the width of the claimed utility model is commensurate with the average width of an automobile, and the length of the utility model is a multiple less than its width. The claimed utility model comprises the following elements: a hitching device, a towing beam consisting of rigid rods, a chassis, and a cargo bed.
Description
УКОРОЧЕННЫЙ ПРИЦЕП ПОВЫШЕННОЙ МАНЕВРЕННОСТИ Область техники CUTTING TRAILER OF ENHANCED MANEURABILITY
Настоящая полезная модель относится к области транспортирования, а именно к прицепам. Предшествующий уровень техники This utility model relates to the field of transportation, namely to trailers. Prior art
Для перевозки небольших грузов по дорогам общего пользования в настоящее время достаточно часто используются прицепы для легковых автомобилей, которые оборудованы тягово-сцепным устройством, обычно шарового типа, а также иными типами сцепных устройств. Шасси распространенных конструкций прицепов имеют одну или две оси, грузовую платформу, ширина которой, как правило, равна или превышает её длину, дышло, состоящее из одной или нескольких, но, чаще всего, не более двух балок или тяг, и сцепной головки на конце дышла. При этом балки дышла и сцепная головка либо жестко закреплены вместе с шасси, либо имеют одну ось для свободы в горизонтальной плоскости относительно шасси прицепа. For transportation of small loads on public roads, trailers for passenger cars, which are equipped with a trailer coupling, usually of a spherical type, as well as other types of coupling devices, are quite often used today. The chassis of common trailer designs have one or two axles, a loading platform, the width of which is usually equal to or greater than its length, the drawbar consisting of one or several, but most often no more than two beams or rods, and a coupling head at the end dyshla At the same time, the drawbar beams and coupling head are either rigidly fixed together with the chassis, or have one axis for freedom in the horizontal plane relative to the trailer chassis.
Из существующего уровня техники известен «ПРИЦЕП К ЛЕГКОВОМУ АВТОМОБИЛЮ» (Патент RU 128173, заявл. 17.12.2012, опубл. 20.05.2013). Прицеп содержит раму, закрепленную по меньшей мере на одной колесной подвеске, смонтированную на раме грузовую платформу, включающую днище и передний, боковые и откидной задний борта, и соединенное с рамой дышло со сцепной головкой. Рама выполнена из соединенных между собой продольных и поперечных балок. Борта грузовой платформы выполнены в виде съемных панелей, состоящих из листов с гофрированным профилем, верхние и боковые кромки которых соединены с элементами жесткости. Панели переднего и каждого из боковых бортов закреплены на раме посредством по меньшей мере двух вертикальных стоек.
Недостатком данного технического решения является то, что оно имеет большие размеры шасси и платформы и не позволяет обеспечить боковую погрузку грузов на платформу. From the current level of technology is known "TRAILER TO THE LUNG CAR" (Patent RU 128173, declared. 12/17/2012, publ. 20/05/2013). The trailer contains a frame fixed on at least one wheel suspension, a loading platform mounted on the frame, including the bottom and front, side and tailgate, and a drawbar connected to the frame with a coupling head. The frame is made of interconnected longitudinal and transverse beams. The sides of the cargo platform are made in the form of removable panels consisting of sheets with a corrugated profile, the top and side edges of which are connected to the stiffening elements. The panels of the front and each of the side boards are fixed to the frame by means of at least two vertical posts. The disadvantage of this technical solution is that it has a large chassis and platform and does not allow for lateral loading of goods on the platform.
Также известен «ПРИЦЕП К ЛЕГКОВОМУ АВТОМОБИЛЮ» (Патент RU 2578653, заявл. 20.11.2014, опубл. 27.03.2016). Недостатком указанного технического решения являются относительно большие габариты, что делает автомобиль с присоединенным прицепом менее маневренным в движении. При хранении такой прицеп занимает много места, что также является отрицательным фактором. Also known is the “TRAILER FOR A LIGHT VEHICLE” (Patent RU 2578653, announced November 20, 2014, published March 27, 2016). The disadvantage of this technical solution is relatively large dimensions, which makes the car with attached trailer less maneuverable in motion. When storing such a trailer takes up a lot of space, which is also a negative factor.
Технической проблемой, решение которой обеспечивается при использовании заявляемой полезной модели, является низкая маневренность существующих прицепов и автопоездов, в составе которых используются прицепы, обусловленная большими размерами существующих прицепов, а также значительные затруднения при погрузке грузов сбоку прицепа, перпендикулярно направлению его движения. A technical problem, which is solved by using the claimed utility model, is the low maneuverability of existing trailers and road trains, which include trailers, due to the large size of existing trailers, as well as significant difficulties in loading cargo from the side of the trailer, perpendicular to its direction of movement.
Раскрытие сущности технического решения Disclosure of technical solutions
Заявляемая полезная модель осуществляется для того, чтобы решить вышеуказанную проблему, и, следовательно, техническая задача настоящей полезной модели заключается в повышении маневренности прицепов и автопоездов, в составе которых используются прицепы, и обеспечении возможности погрузки грузов сбоку прицепа, перпендикулярно направлению его движения. The claimed utility model is carried out in order to solve the above problem, and, consequently, the technical problem of this utility model is to increase the maneuverability of trailers and road trains, which include trailers, and ensure the possibility of loading goods from the side of the trailer, perpendicular to the direction of its movement.
Техническим результатом заявленной полезной модели является повышение маневренности прицепов и автопоездов, в составе которых используются прицепы, путём уменьшения размеров прицепа с сохранением полезной площади грузовой платформы, а также обеспечение возможности погрузки грузов сбоку прицепа, перпендикулярно направлению его движения.
Технический результат достигается тем, что ширина заявляемой полезной модели сопоставима со средней шириной легкового автомобиля, а длина полезной модели кратно меньше её ширины. The technical result of the claimed utility model is to increase the maneuverability of trailers and road trains, which include trailers, by reducing the size of the trailer while preserving the usable area of the loading platform, as well as ensuring the possibility of loading cargo on the side of the trailer, perpendicular to its direction of movement. The technical result is achieved by the fact that the width of the claimed utility model is comparable to the average width of the car, and the length of the utility model is a multiple of its width.

Варианты осуществления Embodiments
Заявляемая полезная модель включает в себя следующие элементы: сцепное устройство (1 на Фиг.1), дышло, состоящее из жёстких тяг (2 на The claimed utility model includes the following elements: coupling device (1 in Fig. 1), the drawbar, consisting of rigid rods (2 on
Фиг.1), шасси (3 на Фиг.1), грузовую платформу (4 на Фиг.1). Figure 1), the chassis (3 in figure 1), the loading platform (4 in figure 1).
Для достижения технического результата заявляемая полезная модель функционирует следующим образом. To achieve a technical result, the claimed utility model operates as follows.
Головка сцепного устройства подвижно крепится к шару тягово- сцепного устройства, закрепленного на автомобиле. Подвижность головки стандартно и всегда ограничена углами в трех плоскостях, при этом свобода в пределах этих углов критически важна для сохранения управляемости сцепки и контакта колес прицепа с полотном дороги и сохраняется в описываемой полезной модели. The head of the coupling device is movably attached to the ball of the trailer coupling mounted on the vehicle. The head mobility is standard and is always limited to angles in three planes, while freedom within these angles is crucial to maintaining manageability of the hitch and contact of the trailer wheels with the road bed and is preserved in the described utility model.
Дышло прицепа состоит из жестких тяг, образующих в боковой проекции подвижную параллелограммную конструкцию (Фиг. 3), и трапецию в верхней проекции (Фиг. 2). The trailer hitch consists of rigid rods, which form in a side projection a movable parallelogram structure (Fig. 3), and a trapezoid in the upper projection (Fig. 2).
Точки крепления осей тяг дышла прицепа к шасси не выходят за пределы колесной базы прицепа. В том случае, если опрокидывающий момент при торможении возникает вокруг передней оси прицепа, описанное размещение точек крепления для тяг дышла создаёт компенсирующий момент, прижимающий шасси прицепа к дороге при торможении и перпендикулярный плоскости движения.
Если опрокидывающий момент при разгоне возникает вокруг задней оси прицепа, тяги дышла создают компенсирующий момент, параллельный плоскости движения, направленный в сторону движения и противоположный опрокидывающему моменту. The attachment points for the axles of the trailer drawbar to the chassis do not extend beyond the trailer wheelbase. In the event that an overturning moment occurs when braking around the front axle of the trailer, the described placement of attachment points for the drawbar creates a compensating moment that presses the trailer chassis to the road during braking and perpendicular to the plane of motion. If a tilting moment occurs during acceleration around the rear axle of the trailer, the drawbar rods create a compensating moment parallel to the plane of movement, directed in the direction of motion and opposite to the tilting moment.
Для компенсации опрокидывающих моментов при разгоне и торможении в описываемой модели применяется подвижная параллелограммная конструкция дышла прицепа, совместно с геометрией точек крепления дышла к шасси прицепа относительно осей прицепа и головки сцепного устройства, а сами точки крепления представляют собой подвижные в плоскости движения петли. To compensate for tilting moments during acceleration and deceleration, the described model uses a movable parallelogram trailer drawbar design, together with the geometry of the drawbar attachment points to the trailer chassis with respect to the axes of the trailer and the hitch head, and the loops in the plane of movement.
Строение тяг дышла заявляемой полезной модели не ограничивается указанной компоновкой тяг дышла, в частности, положение тяг дышла относительно друг друга и их количество может быть изменено с сохранением параллелограммного принципа работы конструкции, например, одна тяга может быть вынесена вперед, а две назад. The structure of the drawbar of the inventive utility model is not limited to the indicated arrangement of the drawbar, in particular, the position of the drawbar relative to each other and their number can be changed while maintaining the parallelogram principle of the design, for example, one thrust can be brought forward and two back.
При переезде через неровности дороги оси прицепа могут находиться на разной высоте, а шасси прицепа может свободно наклоняться вокруг поперечной плоскости движения оси, что возможно благодаря подвижности головки сцепного устройства относительно шара крепления тягово-сцепного устройства автомобиля и подвижной параллелограммной конструкции, образованной тягами дышла, головкой сцепления и шасси прицепа. When moving through road irregularities, the trailer axles can be at different heights, and the trailer chassis can freely bend around the transverse plane of the axle movement, which is possible due to the mobility of the hitch head relative to the ball of the towing hitch and movable parallelogram structure trailer coupling and chassis.
Описываемая полезная модель применима для грузов, длина которых сопоставима с шириной легкового автомобиля-буксировщика, а ширина кратно меньше длины. Примером характерных грузов могут являться такие транспортные средства, как мотоциклы, скутеры, велосипеды, снегоходы, квадроциклы. Такие размеры позволяют размещать и загружать грузы сбоку, перпендикулярно движению, значительно сокращая размеры шасси и платформы прицепа, делая длину прицепа кратно меньше его ширины.
Уменьшенная длина платформы прицепа в сумме с автомобилем - буксировщиком дают меньшие линейные размеры всего автопоезда, что является преимуществом - автопоезд занимает меньше места на проезжей части, более маневренен, что позволяет улучшить управляемость такого автопоезда. Еще одним преимуществом такой компоновки для характерных грузов является маленькая занимаемая площадь для парковки и хранения прицепа, когда он не используется, что весьма важно для личного и, как правило, нечастого использования прицепов для легковых автомобилей. Данная компоновка также предполагает боковую загрузку, что на практике более удобно, так как позволяет загружать необходимые грузы, например, с тротуара, что повышает безопасность погрузки.
The described utility model is applicable to cargoes whose length is comparable to the width of the car-towing vehicle, and the width is a multiple of less than the length. An example of characteristic cargoes can be such vehicles as motorcycles, scooters, bicycles, snowmobiles, ATVs. Such dimensions allow placing and loading loads from the side, perpendicular to the movement, significantly reducing the dimensions of the chassis and platform of the trailer, making the trailer's length a multiple of its width. The reduced length of the trailer platform in total with the towing vehicle gives smaller linear dimensions of the whole train, which is an advantage - the train takes less space on the roadway, is more maneuverable, which allows to improve the controllability of such a train. Another advantage of such a layout for characteristic cargoes is the small footprint for parking and storing the trailer when not in use, which is very important for personal and, as a rule, infrequent use of trailers for passenger cars. This layout also implies a side loading, which is more convenient in practice, since it allows you to load the necessary goods, for example, from the sidewalk, which increases the safety of loading.
