  • the disadvantage of the known technical solution is the increased mass of the suspension and the entire vehicle, due to an increase in the unsprung mass due to the rigid connection of the housing with the electric motor and gearbox to the wheel hub, which, in turn, leads to an increase in the mass and dimensions of the chassis, springs and shock absorbers, which also require increasing the space under the floor of the vehicle for their placement.
  • the technical result is to reduce the weight and dimensions of the suspension and the vehicle, as well as to increase the convenience when using the suspension in public transport by lowering the floor level due to the refusal to use the bridge scheme.
  • Freeing up space in the lower part of the chassis also allows batteries to be placed in this space, which significantly reduces the center of gravity, for example, electric buses in which the batteries are located in the upper part of the chassis, in particular on the roof.

  • the entire transmission and the electric motor are located inside the lever 4, in its cavity .
  • the specified internal cavity of the lever 4 can be divided by a partition into two parts, in one of which the electric motor 5 is located, with the sealing of this cavity from the possible influence of the lubricant on the operation of the electric motor 5.
  • the lever 4 oscillates relative to the hinge of its connection with the chassis of the vehicle around the geometric axis 11. Placing part of the unsprung mass in the swing arm 4 reduces the inertial load in the suspension.

  • the use of a non-planetary gear, that is, engagement with misaligned gears 6, 7 and 8, allows you to distribute the mass of the transmission along the lever 4, that is, to shift its center of gravity closer to the swing axis of the lever around the geometric axis 11.
  • the claimed invention allows to reduce the weight and dimensions of the suspension, which, in turn, reduces the weight of the entire vehicle and increases convenience and comfort when used in public vehicles, especially in electric buses.

Abstract

L'invention se rapporte au domaine des transports terrestres avec un actionneur électrique de roues, notamment des voitures électriques, des bus électriques, des moyens de transport hybrides, etc., dans lesquels un moteur électrique d'entraînement est disposé à proximité immédiate de la roue qu'il entraîne. Le résultat technique consiste en une diminution de la masse et des dimensions de la suspension et du moyen de transport. Ce modèle d'utilité consiste en une suspension à levier indépendante d'un moyen de transport avec roue à moteur, comprenant un moyeu dans lequel est disposé un arbre d'entraînement de la roue, laquelle comprend un levier qui est disposé longitudinalement dans la direction de déplacement du moyen de transport et comporte un bras sous forme d'un corps creux. Dans le corps du levier longitudinal se trouvent un moteur électrique d'entraînement et une transmission dentée via laquelle l'arbre du moteur électrique est relié à l'arbre d'entraînement de la roue. La transmission dentée comprend un pignon moteur et au moins un pignon entraîné qui sont disposés non coaxialement. La première extrémité du levier de la suspension est connectée au moyeu de la roue, et la seconde extrémité est connectée de manière articulée au châssis du moyen de transport de manière à pouvoir faire basculer le levier avec la roue par rapport à l'articulation.
