MULTI-LINK VEHICLE SUSPENSION SYSTEM

摘要

A multi-link suspension includes a frame member, a first member pivotably coupled at a first end to the frame member, and a second member pivotably coupled at a first end to a second end of the first member. A dampener physically couples between the first member and the second member. The dampener limits the rotation of the second member about the second end of the first member to a defined arc. The first member includes a horizontal upper surface to which an electric traction motor providing a shaft output attaches. A power transmission system, such as a flexible belt, couples the shaft output provided by the electric traction motor to a drive hub rotatably attached to a second end of the second member.

主权项

1. A vehicle chassis comprising:
a frame member having a longitudinal axis, an upper surface, a lower surface, and a first end and a second end disposed along the longitudinal axis of the frame member; a first member having a longitudinal axis and a first end and a second end disposed along the longitudinal axis of the first member,
the first end of the first member pivotably coupled at a first pivot point to the lower surface of the frame member at a location intermediate between the first member first end and the first member second end; andthe first member continuously pivotable through a first arc about the first pivot point, the first arc defined by a first angle measured between the longitudinal axis of the frame member and the longitudinal axis of the first member; a second member having a longitudinal axis and a first end and a second end disposed along the longitudinal axis of the second member, wherein the first end of the second member pivotably couples to the second end of the first member; a wheel mount member pivotably coupled to the second end of the second member; and a third member having a longitudinal axis and a first end and a second end disposed along the longitudinal axis of the third member;
wherein the first end of the third member pivotably couples to a stanchion member physically affixed to the first member; andwherein the second end of the third member pivotably couples to the wheel mounting member.
