Airport tug with air suspension

Gepäckschlepper auf Flughäfen benötigen viel Gewicht in Relation zu ihren geringen Abmessungen, um ihre vergleichsweise hohe Antriebsleistung in Vortrieb umsetzen zu können. Dementsprechend verfügen diese Schlepper über eine nur sehr harte und rudimentäre Federung, zumal das Vorfeld von Flughäfen in der Regel wenige Unebenheiten aufweist. Dennoch gibt es bewusst eingebrachte Unebenheiten in Form der so genannten Speedreducer, also von kurzen harten Schwellen, die das Minimieren der Fahrgeschwindigkeit bewirken sollen, andererseits jedoch bei den hart gefederten Schleppern voll bis in den Fahrerbereich durchschlagen. Trotz des hohen Eigengewichts wird daher erfindungsgemäß eine spezifisch ausgebildete Luftfederung für derartige Schlepper vorgeschlagen. Baggage towers at airports require a lot of weight in relation to their small dimensions in order to be able to convert their comparatively high drive power into propulsion. Accordingly, these tugs have a very hard and rudimentary suspension, especially since the apron of airports usually has few bumps. Nevertheless, there are deliberately introduced bumps in the form of the so-called speed reducer, so short hard sleepers, which are intended to minimize the driving speed, on the other hand, however, in the hard-sprung tugs fully penetrate into the driver's area. Despite the high weight, therefore, a specifically designed air suspension for such tractors is proposed according to the invention.

SINGLE WHEEL SUSPENSION BY MEANS OF LEADERS

Independent suspension for a steered air suspended wheel of a bus or lorry

Suspension system and pneumatic system for vehicle

FIELD: transport. SUBSTANCE: set of inventions relates to vehicle suspension system and pneumatic system implementation versions. Vehicle contains frame, front and rear suspension assemblies where one of suspension assemblies includes pneumatic spring, seat, steering assembly, engine., air compressor connected with the frame and communicating with pneumatic spring via fluid, control module electrically connected with air compressor, and auxiliary air outlet. During operation, the air compressor draws air from atmosphere and the same time feeds air to pneumatic spring. Auxiliary air outlet is located under seat and communicates via fluid with air compressor for selective air feeding from air compressor to device other than pneumatic spring. The seat is made removable or swivelling to provide access to auxiliary air outlet. According to the second version, vehicle contains the third suspension assembly, and the first wheel of the first suspension assembly/ the second wheel of the second suspension assembly are located on one end of frame, And the third wheel of the third suspension assembly is located on opposite end of frame. The first and the second valve connect air compressor with the first and the second pneumatic spring via fluid. In the third version, the air compressor is located higher than the centre of front and rear wheels. EFFECT: possibility to use vehicle air compressor with auxiliary air outlet. 29 cl, 16 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 549 226 C2 (51) МПК B60G 17/056 (2006.01) B62K 5/00 (2013.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ (21)(22) Заявка: ИЗОБРЕТЕНИЯ К ПАТЕНТУ 2011153405/11, 28.05.2010 (24) Дата начала отсчета срока действия патента: 28.05.2010 (72) Автор(ы): ЛЕКЛЕРК Даниель (CA), ДЕ ГРАММОН Кристиан (CA) 29.05.2009 US 61/182,459 (43) Дата публикации заявки: 10.07.2013 Бюл. № 19 R U (73) Патентообладатель(и): БОМБАРДИР РЕКРИЕЙШНЛ ПРОДАКТС ИНК.

Air suspension for an air spring-born vehicle axle

The spring (10) has a plunger piston (15) connected with a rolled bellow (12) at a side of an air-suspended vehicle axle. A plunger piston casing (16) of the plunger piston serves as a contact surface for the rolled bellow during compression. A lower edge (17) i.e. supporting edge, of the plunger piston casing is provided with an opening (29) over a circumference (U), and a downwardly opened free space (28) emanating from the opening extends into the plunger piston. The free space is confined to the side through edges (31, 32) by a base (24).

Pneumatic support for a pneumatically supported axle of commercial vehicle

FIELD: machine building.SUBSTANCE: group of inventions relates to a support of a pneumatic spring for a bridge with a pneumatic suspension of a vehicle. Vehicle has support of pneumatic spring. Support of pneumatic spring for the bridge contains the main body, the first fastening facility for connection on the side of the support bridge of the pneumatic spring and the second fastening device for retention of the pneumatic spring and / or damping element. Main body has a middle zone and two support arms, which are located on opposite sides of the middle zone. First fastener is located in the middle zone. Second fastener is provided on each arm. Middle zone and support arms form a single structural element. Main body is made from fibrous composite material.EFFECT: reduced weight of support of pneumatic spring with increase in its strength.12 cl, 3 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 692 025 C2 (51) МПК B60G 11/28 (2006.01) B60G 9/00 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК B60G 11/28 (2019.02); B60G 9/00 (2019.02) (21)(22) Заявка: 2015148107, 09.11.2015 (24) Дата начала отсчета срока действия патента: Дата регистрации: 19.06.2019 (73) Патентообладатель(и): МАН ТРАК УНД БАС АГ (DE) (56) Список документов, цитированных в отчете о поиске: WO 2007057698 A2, 24.05.2007.
