Independent rear suspension having transmission function

Abstract

The invention discloses an independent rear suspension having a transmission function. The rear suspension mainly comprises three parts: a shock absorber, a coil spring and a swing arm, wherein the swinging arm comprises a transmission shaft casing pipe connected with a gearbox, a transmission shaft casing pipe connected with a wheel, an internal sprocket chain transmission mechanism and an outer cover shell. One end of the shock absorber is connected with a connection base fixed on the swing arm, and the other end of the shock absorber is connected with a connection base fixed on a frame, so that the purpose of shock absorption is realized; the coil spring sleeves the shock absorber, so that the loading and buffering functions are fulfilled; and the big side of the swing arm is connected with the wheel, the small side of the swing arm is connected with the gearbox, and a rear wheel is driven by the sprocket chain transmission mechanism in the swing arm. Two devices are connected to the right and left of the rear frame of the vehicle to form a complete independent rear suspension system. The device is simple and reliable in structure, excellent in shock absorption performance, excellent in stability and driving comfort, and more appropriate for vehicles embodied with cross-country performance.

Description

technical field [0001] The invention relates to a vehicle rear suspension device, in particular to an independent rear suspension device with transmission function. Background technique [0002] At present, the rear suspension of motor vehicles on the market is either a non-independent suspension structure in the form of a single trailing arm, or an independent suspension structure, and the most used are double A-arm and multi-link independent suspensions. It is mainly carried and buffered by coil springs, the damping effect is realized by damping shock absorbers, and the force transmission, support and guiding functions of the suspension are realized by double A arms or various connecting rods. The effect is good, but the disadvantage is that the structure is complex and occupies The space is large, the cost is high, the positioning is difficult, and the inclination angle of the rear wheel changes at any time, which affects the life of the tire. [0003] In addition, for v...
