Detailed description of the invention
According to Figure of description and specific embodiment, the utility model is further explained below.
As shown in Figure 1, the straight drive system of a kind of automobile front follow-up steering, comprise lamp body 1, microcontroller 4, rotating shaft 5, rotary encoder 6, disc type electric machine 7, described rotating shaft 5 is connected with one heart with disc type electric machine 7 center shafts, described microcontroller 4 is connected with rotary encoder 6 with disc type electric machine 7 by wire, between described rotating shaft 5 and lamp body 1, be connected by the first support 2, the first described support 2 is fixed on the center-of-gravity position of lamp body 1, guarantees that lamp body 1 can 5 freely rotate around the shaft on horizontal surface.Described disc type electric machine 7 has disc type electric machine 7 rotors, on described disc type electric machine 7 rotors, be a bit connected by the second support 3 with lamp body 1 afterbody shell, or on described disc type electric machine 7 rotors, be a bit connected by the second support 3 with lamp body 1 front-end case as shown in Figure 2.By the first support 2 and the second support of support 3 to lamp body 1, guarantee that lamp body 1 central axis is vertical with disc type electric machine 7 central axis.
Described rotary encoder 6 is absolute type encoder or magslip, and described rotary encoder 6 is for obtaining the angular signal of disc type electric machine 7, and described rotary encoder 6 is arranged on disc type electric machine 7.
The rotation direction of described lamp body 1 is identical with disc type electric machine 7 rotation directions.
Described disc type electric machine 7 is servo permagnetic synchronous motor or servo asynchronous dynamo or the servo permagnetic synchronous motor of axial flux structure or the servo asynchronous dynamo of radial flux outer-rotor structure.
