A 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 imitate the leg structure evolved by kangaroos to adapt to the natural environment, and to design an imitation kangaroo leg suspension with excellent structure and performance. The technical solution adopted in the present invention is: a MR imitation kangaroo leg suspension, which includes a vehicle body, a thigh tendon spring, a thigh muscle MR damper, a calf bone rod, a kingpin, a thigh bone rod, a calf tendon spring, and a calf muscle MR damper device, Achilles tendon spring, Achilles tendon muscle MR damper and foot bone rod; the upper end of the femur rod is hinged with the vehicle body and makes the hinge point constitute the hip joint; the lower end of the femur rod is hinged with the upper end of the calf rod and makes the The hinge point constitutes the knee joint; the lower end of the calf bone rod is hinged with the middle part of the foot bone rod so that the hinge point constitutes the ankle joint, and the end of the foot bone rod is connected to the wheel through a kingpin; the lower end of the Achilles tendon muscle MR damper Hinged with the upper end of the 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
