Abstract

The invention discloses an imitation kangaroo leg suspension with bionic joints, comprising a leg bone rod, a calf bone rod, a foot bone rod, a bionic joint, a connecting rod and a limit mechanism; the upper end of the femur rod and the vehicle body pass through the bionic hip joint Hinged, the lower end of the femur rod and the upper end of the calf rod are hinged with the bionic knee joint, the lower end of the calf rod and the upper end of the foot rod are respectively hinged with the bionic ankle joint, the bionic hip joint and the bionic ankle joint are connected by MR damper Ⅰ, the foot The lower end of the bone rod and the lower end of the MR damper II are hinged to the center of the wheel, and the upper end of the connecting rod is hinged to the limit mechanism; the bionic joint includes a disc, an arc groove, and a circular hole. Fill magnetorheological fluid, arc spring, and arc damping block. The invention imitates the leg structure of kangaroo legs and the excellent characteristics of biological joints through the characteristics of kangaroo's unique motion composition, reasonable leg structure ratio, and very characteristic motion form, so that the vehicle has good passability and 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 ...
