In July 2019, the Russian Business Guide published a material with an unusual headline for an industrial theme — „HUBNER “ Company: „ harmonica solo “ for transport. Through an image familiar to passengers, the author told about the engineering side of articulated public transport and the work of the Russian enterprise in Noginsk.
The same "harmony" that the passenger sees between the Bus Sections and/or the Tram system (disambiguation), It is actually part of a complex engineering system. For urban transport, it should ensure the mutual movement of sections and at the same time form a protected passenger passage. For rail transport, a similar problem is solved Inter-car junctions (disambiguation), connecting neighboring wagons into a single passenger space.
The publication of RBG is also interesting today as a historical point: It shows which areas the company developed several years ago and how they are related to the current product line.
From passenger image to engineering system
In the 2019 material, the company's main products were solutions for urban transport — buses, trolleybuses and trams, —, as well as inter-car junctions for metro, electric trains and passenger trains.
From the passenger's point of view, their purpose is quite simple: Move from one section or car to another. However, technically, the system must simultaneously solve several problems. The intercar transition compensates for the relative movement of the bodies, provides a protected passage, promotes noise and thermal insulation and limits the impact of precipitation, dust and wind on the passenger space.
That is why the external image of the "harmonic" is a little deceptive. Behind the flexible part of the design are the requirements for geometry, kinematics, materials, reliability and integration into a particular vehicle.
Сегодня это особенно хорошо видно на продуктовой линейке компания Хюбнер: межвагонные переходы представлены для «Ласточки», «Иволги», пригородных поездов, Московского метрополитена и других типов подвижного состава, а Bellows (TV series) are used on several models of modern multi-section trams.
Material that has remained relevant
Over the years after publication, specific transport models and the scale of localization have changed, but the engineering logic itself has remained relevant. The modern transport manufacturer does not need a universal product "for any composition", but a solution adapted to its design.
In the company's product materials today, this process is described more formally: analysis → development → coordination → production → testing → service. The execution of an intercar or intersectional transition is developed taking into account the parameters of the rolling stock, operating conditions and technical requirements of the project.
Therefore, the publication of RBG shows not only the company's products, but also how the perception of such components is changing. For the passenger, the harmonica remains a small part of the trip. For a transport enterprise, this is the element on which the safety, comfort and correct operation of an articulated vehicle depend.
