Specific embodiment
With reference to the accompanying drawings and examples, the present invention is described in further detail.
The present embodiment provides a kind of vehicle independent steering assemblies, and overall structure is simple, and transmission chain is short, occupy interior empty
Between it is few, promote interior space utilization rate and drive control precision to greatest extent.
Referring to attached drawing 1-4, the vehicle independent steering assembly include: bracket, retarder 4, steering-engine 5, rack gear 9,
Gear shaft 11, rack gear pedestal 12, rotary angle transmitter 14 and gear shaft housing 15；
Retarder 4 is mounted in bracket by retarder fixed plate 2, and steering-engine 5 is mounted on bracket by steering engine supporting plate 6
It is interior；Rack gear pedestal 12 is fixedly mounted in bracket, and gear shaft housing 15 is fixedly connected with rack gear pedestal 12, and rack gear 9 passes through two
Linear bearing 13 is mounted on rack gear pedestal 12；Gear shaft 11 is mounted in gear shaft housing 15 by wheel bearing 10；Corner
Sensor 14 is fixedly connected with gear shaft housing 15；
The output end of steering-engine 5 is connect with retarder 4, and the output shaft of retarder 4 passes through flat key and the one of gear shaft 11
The other end of end connection, gear shaft 11 is equipped with centre bore, and the induction end of rotary angle transmitter 14 is mounted in the center of gear shaft 11,
Wheel and rack 9 on gear shaft 11 is meshed, and one end of rack gear 9 is equipped with the connector connecting with track rod.Rotation angular sensing
Device 14 is used for the rotational angle of real-time monitoring gear shaft 11, to determine the angular errors of deflecting roller (as it is possible that occurring intermediate
Transmission failure, leads to that steering engine has turned but deflecting roller does not rotate).
In above scheme, specifically, the bracket includes: bracket right panel 1 and bracket left plate 7；Bracket right panel 1 and bracket
