Embodiment Construction

[0030] Fundamental:

[0031] Different external force F is used to produce different deformation ΔH to the elastic body with variable cross-section, forming different reaction force, achieving force balance with external force F, forming a corresponding stiffness K for the elastic body, and realizing the function of variable stiffness.

[0032] Design the main and auxiliary adjustment chambers, in order to better make up for the requirements of different stiffness values, and at the same time improve the sensitivity of the adjustable stiffness suspension cushion device and the heat dissipation function of the elastic body, and solve complex theoretical calculations;

[0033] Two-stage conical elastic bodies are designed to be connected in series. According to the stiffness theory of series elastic elements: when the external force F is small, the first elastic body works; when the external force F is large to a certain extent, the first elastic body and the second elastic body ...

Abstract

The invention discloses an adjustable rigidity suspension cushion device which comprises a first stage conical elastic body (6) and a second stage conical elastic body (10) of two stages of variable cross sections; a connecting plate (4), the first stage conical elastic body (6), a connecting plate (9), the second stage conical elastic body (10) and a connecting plate (11) are connected in sequence; a stretching screw (1) passes through a central hole of the connecting plate (9), a central hole of the first stage conical elastic body (6), and a screw hole of the connecting plate (4), and is locked through a nut (2); the centre of the lower part of the first stage conical elastic body (6) is a first regulating cavity body (7); auxiliary regulating cavity bodies (5) are arranged on the first stage conical elastic body (6) and the second stage conical elastic body (10) and consist of a plurality of holes from outside to inside; the cavity body of the auxiliary regulating cavity body (5) can be hollow or filled with lubricant fillers with low elasticity; and an auxiliary regulating rod is applied in coordination with the auxiliary regulating cavity bodies (5).

Description

technical field [0001] The invention relates to a suspension cushion device with adjustable stiffness, which is suitable for the suspension cushion structure of mechanical equipment with dynamic load, and has special functions of vibration reduction and noise reduction, especially the rear suspension of automobile powertrain and vehicle body Padded structure. Background technique [0002] As for the suspension system, which is a 6-DOF system, it is required to decouple the resonance of the powertrain in all directions, and at the same time control a certain displacement. [0003] The suspension is to isolate the vibration of the engine (torque change, engine centrifugal inertial force, reciprocating inertial force, etc.) as much as possible, and to minimize the displacement and vibration of the engine caused by the excitation of the engine by the road, rapid acceleration, rapid deceleration and sharp turning. [0004] The design and matching of automobile engine and body mo...
