Novel passive suspension comprising inertial container

Abstract

The invention discloses a novel passive suspension comprising an inertial container. The novel passive suspension is characterized by comprising a supporting spring (1), an auxiliary damper (2), the inertial container (3), a main damper (4) and an auxiliary spring (5); the auxiliary damper (2) and the inertial container (3) are connected in series to form a low-frequency vibration filtering device; the auxiliary spring (5) and the main damper (4) are connected in parallel to form a high-frequency vibration filtering device; the low-frequency vibration filtering device and the high-frequency vibration filtering device are connected in series to form a full-frequency vibration filtering device; the full-frequency vibration filtering device is connected with the supporting spring (1) in parallel; the upper end of the parallel structure is hinged to a vehicle body, and the lower end of the parallel structure is hinged to wheels. The novel passive suspension can buffer and attenuate impact of a concave-convex road surface at a high-frequency band and a low-frequency band so that a vehicle can adapt to the road surface with full-frequency vibration, the riding comfort of the vehicle can be effectively improved, and the influence of unevenness of the road surface on the vehicle body can be reduced.

Description

technical field [0001] The invention relates to a novel passive suspension containing an inerter. Background technique [0002] Vehicle suspension is the general term for all transmission devices between the car body and the axle, mainly composed of springs, dampers and guide devices. A spring and a damper form the simplest form of automobile suspension, which can buffer the impact force caused by uneven road surface and transmitted to the frame or body, attenuate the vibration caused by it, and ensure that the vehicle can run smoothly. [0003] Traditional mechanical vibration isolation components mainly include springs and dampers. In 2002, Professor Smith of the University of Cambridge proposed a new type of vibration isolation component, the inerter, and applied the inerter to the suspension of the car, which has achieved good results. shock absorbing performance. Therefore, research on the application of inerters in automobile suspensions has received more and more at...

Problems solved by technology

However, the two-stage structure of the suspension will reduce the static stiffness of the automobile suspension, and the reduction of the static stiffness will increase the deflection of the suspension spring, which puts high demands on the structural design of the suspension.
