Embodiment

[0062] Attached below Figure 1-9 The present invention is described in further detail so that those skilled in the art can implement it with reference to the description.

[0063] as attached figure 1 As shown, the steer-by-wire device integrated with the steering mechanism and suspension of the present invention adopts a McPherson suspension structure. Connect with the universal joint 27 and transmit the torque to the universal joint 27; the universal joint 27 is connected with the top of the strut shaft 25 through a flat key to transmit the torque from the worm wheel 30 to the strut shaft 25; the upper part of the coil spring 7 passes through The coil spring upper tray 4 is supported on the connecting plate assembly 2, and the connecting plate assembly 2 is fixedly connected with the vehicle body by bolts. There is a front buffer block 5 inside the coil spring upper tray 4, and there is a dust cover 6 between the front buffer block 5 and the upper sealing plug 8 of the sl...

Abstract

The invention discloses a steering mechanism and suspension integrated steer-by-wire device which includes a steering motor, a decelerating mechanism connected with an output end of the steering motor, a sliding column shaft connected with the decelerating mechanism and a sliding column shaft sleeve which is matched with the sliding column shaft through a sliding rotating bushing for mounting, sothat the sliding column shaft and the sliding column shaft sleeve can slide relatively in the axial direction and rotate simultaneously in the radial direction. The outer portion of the lower end of the sliding column shaft sleeve is connected with a hub motor casing of a wheel through a steering knuckle, so that a hub motor and the sliding column shaft rotate synchronously. The invention discloses an automobile. The steering mechanism and suspension integrated steer-by-wire device can meet the performance requirements of the finished automobile; particularly, a better scheme is provided for the adoption of steer-by-wire by large heavy duty vehicles, and the steering mechanism and suspension integrated steer-by-wire device has the advantages of being simple in structure and small in occupied space, having easiness in technology implementation and facilitating the integration with the finished vehicle.

Description

technical field [0001] The invention relates to the field of steering-by-wire steering of automobiles, in particular to a steering-by-wire steering device integrated with a steering mechanism and a suspension and an automobile. Background technique [0002] Steering by wire originated from the fly-by-wire control system applied in aerospace technology in 1972. With the continuous development of electronic technology and computer technology, major automobile companies have launched research on steering by wire technology. In Europe, in 1998, the German ZF company carried out the research and development of the steer-by-wire system, and the "Brite-Eu Ram'X-by-Brite-Eu Ram'X-by- wire' project", dedicated to the research on the realization, reliability and safety of steer-by-wire system. [0003] In Asia, Toyota Corporation of Japan launched the FT-EVⅡ steer-by-wire concept car in 2010, which controls the steering, acceleration and braking of the vehicle through knobs and butto...
