Detailed Description
The invention will be further described with reference to the accompanying figures 1-2 and the specific embodiments.
As shown in fig. 1-2, an apparatus for triggering the whole vehicle to steer by turning a steering wheel of an electric forklift includes the steering wheel 1, a steering assembly 2 having a steering shaft and linked with the steering wheel 1, a combination switch 3 mounted on the steering assembly 2, and a steering motor 6 mounted on a vehicle body, and further includes:
an angle sensor 7 installed at the bottom of the combination switch 3 for sensing the rotation angle and the motion of the steering shaft of the steering assembly 2 and being triggered when the steering wheel 1 rotates;
the signal processor 4 is connected with the angle sensor 7 through electric signals and used for converting the pulse signals output by the angle sensor 7 into voltage signals and outputting the voltage signals;
and the controller assembly 5 is used for processing the voltage signal output by the signal processor 4 and generating a starting signal to start the steering motor 6, and the controller assembly 5 is installed on the vehicle body.
As shown in fig. 1, the signal processor 4 is mounted on the frame 8 and connected to the angle sensor 7 through a signal line; the installation height of the signal processor 4 is lower than that of the steering assembly 2; the steering motor 6 is provided with a signal wiring terminal which is in electric signal connection with the output end of the controller assembly 5; the output end of the signal processor 4 is connected with the input end of the controller assembly 5 through a signal wire.
When the whole vehicle is electrified, when an operator rotates the steering wheel 1, the steering wheel 1 drives a steering shaft of the steering assembly 2 to rotate, meanwhile, an angle sensor 7 arranged at the bottom of a combined switch 3 on the steering assembly 2 outputs signals along with the rotation of the steering shaft, and pulse signals output by the angle sensor 7 are converted into voltage signals and transmitted to a controller assembly 5 after being processed by a signal processor 4, so that a steering motor 6 is driven to operate through the controller assembly 5, and the hydraulic power-assisted steering of the vehicle is realized; when the operator does not turn the steering wheel 1, the angle sensor 7 outputs no pulse signal, the vehicle has no steering demand, and the controller assembly 5 controls the steering motor 6 to stop running.
