Wheelspan it is constant, and then can stablize be operated.When electric control lock unlocks, the sticking department of electric control lock transfers to the first company successively
The dynamic linkage part 22 of portion 12 and second, the first linkage part 12 and the second linkage part 22 are unlocked by original lock-out state, and first interlocks
Relative direction is scalable between the linkage part 22 of portion 12 and second, and the first wheel and Second wheel being now coaxially disposed can be distinguished
Steering operation is carried out, while also can adjust the wheelspan between coaxial wheel.
Specifically, in the electric-control system normal work of automobile, electric control lock can be utilized to lock the first linkage part 12 and the
Two linkage parts 22, automobile can ensure safety traffic under electric-control system and the dual guarantee of linkage, be this reality as shown in Figure 2
Apply the knot of wheel state of the linkage of the electric automobile coaxial wheel of example in electric automobile normally travel forward or backward
Structure schematic diagram, now electric control lock be in the lock state, coaxial wheel interlock；And when automobile is in some special states, such as such as
It is the structural representation of wheel state of the linkage of electric automobile coaxial wheel in electric automobile cross running shown in Fig. 3
Figure, it is wheel of the linkage of electric automobile coaxial wheel of the invention when electric automobile spot turn travels as shown in Figure 4
The structural representation of sub- state, electric control lock can be then unlocked in the case of these, the first linkage part 12 and the second linkage part 22 are relative
It is scalable so that two coaxial wheels can independent steering.If the electric-control system of automobile breaks down so that coaxially wherein
The rolling mechanism of one wheel loses normal operating conditions, and the first linkage part 12 and still can be now locked using electric control lock
Two linkage parts 22, set by the gearing of the first wheel and Second wheel, the first wheel can be by the steering motor of Second wheel
Driving, and then realize it is synchronous with Second wheel steering, ensure the safety traffic of automobile.
Embodiment two
Fig. 4 is refer to, the difference of embodiments of the invention two and embodiment one is the angle between cursor and wheel shaft
It is different.As Figure 1-3, first cursor 11 and the second cursor 21 are set with wheel shaft into obtuse angle in embodiment one.Such as Fig. 4 institutes
Show, first cursor 11 and the second cursor 21 are then set at a right angle with wheel shaft in embodiment two.
Further, the electric control lock of embodiment one and embodiment two can also be in released state in normally travel, only
When the control for having wheel is broken down, electric control lock is just locked, to ensure traffic safety.
Further, the linkage of embodiment one and embodiment two is preferably provided between two front-wheels of automobile, if
Need four-wheel to interlock, then linkage described in one also can be set in front wheels and rear wheels respectively.
In summary, the linkage of electric automobile coaxial wheel provided by the invention, which has to ensure to control in computer, is
System failure when, control coaxial wheel synchronously turn to the advantages of.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
