Abstract

The invention discloses an ISD (inerter-spring-damper) integrated suspension. The ISD integrated suspension comprises an air spring, a first sleeve cylinder, a ball screw inerter, a second sleeve cylinder, and a damping mechanism, wherein the air spring comprises an air bag, an air spring sealing cover is arranged on the upper end of the air bag, and an air spring piston is arranged on the lower end of the air bag; the first sleeve cylinder is fixedly arranged on the air spring sealing cover, and is positioned in an inner cavity of the air bag; the second sleeve cylinder is glidingly sheathed on the outer wall of the first sleeve cylinder, and the air spring piston is sheathed on the outer wall of the second sleeve cylinder; when the first sleeve cylinder and the second sleeve cylinder are relatively moved, a screw is driven to move, so as to drive a ball screw nut to rotate. The ISD integrated suspension has the advantage that by optimizing the design of internal structures of the air spring, the ball screw inerter and a damper, and adopting the integrated design method of elements, a three-element ISD integrated suspension system is designed, and is applied to engineering, the engineering layout is easy, and the property is excellent.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an ISD integrated suspension. Background technique [0002] Suspension is the general term for all force-transmitting connection devices between the frame (or load-bearing body) and the axle (or wheel) of an automobile. Its function is to transmit the force and torque acting between the wheel and the frame, and Buffer the impact force transmitted to the frame or body from the uneven road surface, and reduce the vibration caused by it, so as to ensure that the car can run smoothly. In recent years, with the improvement of people's requirements for car performance, the traditional car suspension can no longer meet people's needs. It is one of the research focuses in the field of vehicle engineering to find a traditional suspension structure system that can break through the classical vibration isolation theory and further improve the vibration isolation performance of the suspension. "I...
