Description
Technical field
This creation is a kind of vehicle electric power-assisted transfer, and especially one kind can stablize handle, and electronics is avoided to move
The arbitrary start of power assistant steering device, further elimination group found tolerance and improve the vehicle electric power-assisted of signal interpretation precision
Transfer.
Background technology
Be currently used in vehicle (such as:Beach buggy, multi-function vehicle) steering pre twist, main system is through below handle
The public thread of the upper shaft connected corresponds to the female thread of lower rotary shaft connected above occlusion wheel to generate resistance, and can
Achieve the effect that pretwist, since lower rotary shaft mutually blocks relative to the other end of female thread and the upper rotor of a torsion sensor
It connects, when female thread of the male thread occlusion lower rotary shaft of upper shaft drives lower rotary shaft rotation, the upper rotor meeting of torsion sensor
And then it rotates, at this point, torsion sensor can detect the rotational angle of upper rotor by lower rotor, therefore is notified that motor opens
Dynamic operating enables motor end to be driven to drive lower rotary shaft with upper shaft in rotating in same direction with it, thereby provides driver suitably
Steering assistance power assists driver's ease rotation steering wheel.
However, above-mentioned pre twist system is mutually twisted generation resistance using male and female thread, this friction formula device is through using one
During section in the future, thread form can be caused to wear so that pre- torsion force gradually changes and influence the operating handle of steering wheel in the future.
