An MR imitation kangaroo leg suspension

Abstract

The invention relates to an MR imitation kangaroo leg suspension, which belongs to the technical field of automobile suspension. The purpose of the invention is to design an imitation kangaroo leg suspension with excellent structure and performance by imitating the leg structure evolved by the kangaroo to adapt to the natural environment. The technical scheme adopted by the invention is as follows: an MR imitation kangaroo leg suspension comprises a body, a thigh tendon spring, a thigh muscle MR damper, a lower leg bone rod, a kingpin, a thigh bone rod, a lower leg tendon spring, a lower leg muscle MR damper, an Achilles tendon tendon tendon spring, an Achilles tendon MR damper and a foot bone rod; An upper end of that femoral bone rod is articulate with the vehicle body and the articulation point constitutes a hip joint; A low end of that thigh bone rod is articulated with an upper end of the low thigh bone rod and the articulation point constitutes a knee joint; A low end of that lower leg bone rod is articulate with a middle part of the foot bone rod to form an ankle joint, and an end of the foot bone rod is connected with a wheel through a kingpin; A low end of that MR damper of the Achilles tendon muscle is articulate with an upper end of a foot bone rod.

Description

technical field [0001] The invention relates to an MR imitation kangaroo leg suspension, which belongs to the technical field of automobile suspension. Background technique [0002] Automobile suspension is a buffer and shock absorbing device that elastically connects the frame and the axle (or wheel), and its quality has an extremely important influence on the passability, ride comfort and stability of the automobile. [0003] Car suspension is usually composed of three parts: vibration isolation spring, vibration damping device and guide mechanism. The vibration isolation spring is the main part of the suspension, and its function is to support the suspension quality and ease the impact load transmitted to the vehicle body from the road. The damping device acts as a damper that dampens vibrations. The guiding mechanism is used to control the positioning of the wheels and the attitude of the body to ensure the normal driving of the car. According to different control met...

AI Technical Summary

Problems solved by technology

Since the spring stiffness and the damping coefficient of the shock absorber are not adjustable, the passive suspension cannot change with the external road conditions. It can only guarantee the optimal compromise of performance on a specific road and speed, and cannot satisfy ride comfort and handling stability at the same time. requirements

The semi-active suspension uses a damper whose damping coefficient can be adjusted in a large range, so that it can only adapt to a small number of road conditions and vehicle conditions
