Abstract:
Изобретение относится к автомобилестроению, а именно к конструкции подвески. Подвеска транспортного средства содержит раму, четыре одинаковых рычага, предназначенных для соединения со ступицами соответствующих колес, и торсионные стержни, соединенные с рычагами. Два свободно вращающихся торсионных стержня с углом скручивания под нагрузкой, составляющим 1-5°, образуют переднюю и заднюю оси. Торсионные стрежни прикреплены к раме через подшипниковые узлы и установлены параллельно. Середины торсионных стержней соединены между собой тягой с возможностью синхронного осевого поворота торсионных стержней на угол в пределах от -45° до +45° относительно нейтрального положения. К каждому торцу торсионного стержня прикреплен рычаг со ступицей соответствующего колеса. Рычаги одной оси прикреплены к концам соответствующего торсионного стержня, установлены параллельно и направлены в противоположные стороны. Рычаги каждой стороны подвески - правой или левой - направлены в противоположные стороны. Достигается создание условий для опирания одновременно всех четырех колес на дорогу, как при прямолинейном движении, так и при наездах на препятствие.
Abstract:
The invention relates to an actively adjustable wheel suspension (10) for the wheels of an axle of a motor vehicle. Each wheel is articulated to a vehicle body by means of a plurality of wheel-guiding elements and each wheel is operatively connected to a rotary actuator (12), which is supported at the vehicle body and has a rotary rod (14). The two rotary actuators (12) can be controlled by means of a control unit (20) for the active adjustment. The invention is characterized in that the rotary actuators (12) and the rotary rods (14) of the rotary actuators (12) are oriented in a motor-vehicle longitudinal direction (FL) and that the rotary actuators (12) each have a brace (16, 16', 32) oriented in a motor-vehicle transverse direction (FQ) for torque support.
Abstract:
A twist beam (22) for a suspension assembly (20) comprises a base portion (44) and side walls (46) presenting an open U-shaped cross-section and a bulged middle section (24). The twist beam (22) includes end sections (56, 58), the middle section (24), and transition sections (60, 62) each extending from one of the end sections (56, 58) to the middle section (24). The width (w) and the height (h) of the twist beam (22) increase along the transition sections (60, 62) to the middle section (24). The width (w) and the height (h) of the middle section (24) are greater than the width (w) and the height (h) of the end sections (56, 58). The cross-sectional area of the bulged middle section (24) is typically 10% to 30% greater than the cross-sectional area of the end sections (56, 58).
Abstract:
A tubular twist beam comprises a tubular body (20) including a U-shaped groove (22), tubular end sections (28), and transition sections (26) therebetween. The width w of the U- shaped groove (22) decreases continuously from each transition section (26) to a center point C of the tubular body (20) and is narrowest at the center point C to shift stress from the transition sections (26) to an area around the center point C. The tubular body (20) also includes depressions (24) along side walls (38) of each transition section (26) to direct stress to the underside of the U- shaped groove (22) and further balance the stress levels along the length of the tubular body (20). Thus, the tubular body (20) can be formed with a reduced thickness t and thus a reduced weight without sacrificing performance.
Abstract:
A die (20) used to form a metal tube into a tubular twist beam part (22) having a U-shaped torsion section 66 is provided. The die (20) includes a punch (44) and side form blocks (34) which simultaneously engage a metal tube and form the metal tube into the tubular twist beam part (22). The form blocks (34) have a curved profile which depends on the desired profile of the tubular twist beam part (22) to be formed. The die (20) includes horizontal spacer blocks (38) and vertical spacer blocks (32) restricting movement of the punch (44) and form blocks (34). The spacer blocks (32), (38) can have various different dimensions and can be easily removed and replaced to adjust the closing position of the die (20) and thus form multiple tubular twist beam parts (22) each having a different dimension and different roll rate.

A suspension system (12) for a machine (10) is disclosed. The suspension system may have a front torsion axle assembly (24) with a first arm (56) connected at a first end (56a) to a first shaft (54), and a first axle (58) connected to a second end (56b) of the first arm. The suspension system may also have a rear torsion axle assembly (26) with a second arm (56) connected at a first end (56a) to a second shaft (54), and a second axle (58) connected to a second end (56b) of the second arm. The suspension system may further have a frame (14) connected to an end of the first shaft and an end of the second shaft. The second ends of the first and second arms are oriented within common angular quadrants defined by a coordinate system having an axis passing through the first ends of the first and second arms and aligned with a travel direction of the machine.
