Abstract

The invention discloses a bionic kangaroo leg suspension with a bionic joint, which comprises a leg bone rod, a leg bone rod, a foot bone rod, a bionic joint, a connecting rod and a limiting mechanism. An upper end of that thigh bone rod is articulate with the body through the biomimetic hip joint, A low end of a thigh bone rod and an upper end of a lower thigh bone rod are articulate with a biomimetic knee joint, a lower end of that thigh bone rod and an upper end of a foot bone rod are articulated with a biomimetic ankle joint respectively, the biomimetic hip joint and the biomimetic ankle joint are connected through an MR damper I, the lower end of the foot bone rod and the lower end of the MR damper II are articulated with a wheel center, and the upper end of the connecting rod is articulated with a limiting mechanism; The biomimetic joint comprises a disk, an arc groove, a circular hole, sealing rings are arranged on both sides of the arc groove, magnetorheological fluid is filledin the arc groove, an arc spring and an arc damping block are arranged in the arc groove. The invention imitates the leg structure of the kangaroo leg and the excellent characteristics of biologicaljoints through the unique movement constitution of the kangaroo, the reasonable leg structure proportion, the extremely characteristic movement form and the like, so that the vehicle has good passingperformance, stability and comfort.

Description

technical field [0001] The invention relates to the technical field of automobile suspension, in particular to an imitation kangaroo leg suspension, in particular to an imitation kangaroo leg suspension with bionic joints. Background technique [0002] Automobile suspension is the general term for all force-transmitting connection devices between the frame and the axle of the automobile. Its function is to transmit the force and torque between the wheel and the frame, and to buffer the impact force transmitted to the frame or body from uneven roads. , and reduce the vibration caused by it, its quality has an extremely important impact on the passability, ride comfort and stability of the car. [0003] Studies have found that various organisms in the biological world have played a vital role in the development of human society, and the application of bionics to solve problems in practical life has been generally recognized by the academic community. The kangaroo legs have a ...
