Abstract

The invention discloses a double-fork-arm suspension structure capable of steering in all directions based on a hub motor. The double-fork-arm suspension structure comprises the hub motor, double forkarms used for being connected with a vehicle body and a supporting structure used for supporting the vehicle body, wherein an upper connecting support and a lower connecting support which are arranged up and down are fixed on the hub motor; a steering engine assembly capable of enabling a tire to rotate within the range of -90 degrees to 90 degrees is connected between the upper connecting support and the supporting structure; the steering engine assembly comprises a driven gear mechanism fixed to the upper connecting support and a driving gear mechanism meshed with the driven gear mechanismand fixed to the supporting structure, and the upper connecting support and the lower connecting support are each connected with a fork arm in a hinged mode. According to the invention, a steering pull rod of a traditional double-fork-arm suspension structure is omitted, and the steering motor directly drives a steering knuckle assembly to rotate around a virtual main pin, so that +/-90-degree full steering of the four wheels is achieved. The vehicle can achieve various advancing modes such as straight advancing, oblique advancing, different-direction steering, transverse traveling and pivot steering.

Description

technical field [0001] The invention relates to the technical field of automobile floor, in particular to a double-wishbone suspension structure based on a hub motor and capable of omnidirectional steering. Background technique [0002] As the country pays more and more attention to new energy, various electric vehicle technologies emerge in an endless stream, among which hub motors are one of the representatives. Hub motor technology integrates power, transmission and braking devices into the hub, thus greatly simplifying the mechanical part of electric vehicles. [0003] Due to the increasing number of vehicles in big cities, the driving space is becoming more and more narrow. In order to reduce the limitation of the driving space on the car, the all-round four-wheel steering technology came into being. The all-round four-wheel steering technology can realize the steering of vehicles in a small space, and can also realize oblique travel, sideways steering, reverse steeri...
