Abstract

The invention discloses a semi-active suspension system suitable for a hub motor driven virtual rail train, which comprises an electric wheel magneto-rheological suspension damping mechanism, a suspension system assembly and a steering execution mechanism, the electric wheel magneto-rheological suspension damping mechanism is connected with an electric wheel, the electric wheel magneto-rheological suspension damping mechanism is connected with the suspension system assembly, and the electric wheel magneto-rheological suspension damping mechanism is connected with the steering execution mechanism. The suspension system assembly is connected with the frame, one end of the steering execution mechanism is connected with the suspension system assembly, and the other end of the steering execution mechanism is connected with the frame. The steering execution mechanism controls the electric wheel magneto-rheological suspension damping mechanism through the suspension system assembly so as to enable the electric wheel to steer. According to the semi-active suspension system suitable for the hub motor driven virtual rail train, through active control over the magneto-rheological body suspension in the electric wheel, real-time adjustment of the rigidity and damping of the magneto-rheological body suspension is achieved, active vibration reduction in the electric wheel of the hub driven vehicle is achieved, and the riding comfort of the hub-driven vehicle is improved, and the service life of the electric wheel is prolonged.

Description

technical field [0001] The invention belongs to the technical field of rail trains, and in particular relates to a semi-active suspension system suitable for driving virtual rail trains driven by hub motors. Background technique [0002] In-wheel motor driven virtual track trains are driven by all-wheel in-wheel motors (3 carriages with 6 axles and 12 motors and above), without laying steel rails, and setting virtual guide rails (line inspection) directly on urban roads without damaging the road surface. It consists of hinged carriages with trajectory following capability, enabling unmanned driving. Virtual rail train combines the advantages of large passenger capacity of urban rail transit system (especially tram), strong adaptability of road public transportation system, low cost, and flexible route planning. It has short project construction period and small infrastructure investment. It is characterized by flexible scheduling and is a brand-new medium-volume urban publi...
