The principle of work of the active steering system of vehicle of employing cycloidal-pin wheel described in the utility model mechanism:

The wheeled transmission device 49 of cycloidal pin in the active steering system of vehicle of described employing cycloidal-pin wheel mechanism has two separate input ends, a common mouth.Input end of input control of steering handwheel 47 wherein, the input control another one input end of motor 28, mouth is connected to deflector 51.Power has two transfer routes:

---steering column 48---input shaft 21---No. 1 gear 12---No. 2 gears 33---pin braces hollow shaft 14---pin tooth 8---Cycloidal Wheel 39---roller 37---pin 38---output mechanism support shaft 46---No. 4 gears 41---No. 3 gears 3---spool 60---deflector 51 that torsion bar 61---turns to pinion shaft 1---of route 1: steering handwheel 47.

---No. 5 gears 30---No. 6 gears 23---tween drive shaft 26---magnetic clutch 31---eccentric shaft 18---No. 5 bearings 36---Cycloidal Wheel 39---roller 37---pin 38---output mechanism support shaft 46---No. 4 gears 41---No. 3 gears 3---spool 60---deflector 51 that torsion bar 61---turns to pinion shaft 1---of route 2: motor 28.

Electric energy when saving normal work, magnetic clutch 31 is selected electric lost magnetic clutch.When motor 28 trouble free, magnetic clutch 31 power-off adhesives, tween drive shaft 26 and eccentric shaft 18 are connected as a single entity.When only route 1 is worked, motor 28 is freely servo-actuated, because 39 pairs of pin teeth 8 of Cycloidal Wheel have antagonistic force, this antagonistic force can be applied to steering handwheel 47, can disturb driver's operation; When motor 28 fault, magnetic clutch 31 energising disconnects, and now route 1 still can normally be worked and is not subject to the impact of electrical fault.

By adjusting the number of teeth of the number of teeth of No. 1 gear 12 and No. 2 gears 33, No. 3 gears 3 and No. 4 gears 41, No. 5 gears 30 and the number of teeth of No. 6 gears 23, the number of teeth of the Cycloidal Wheel of cycloidal-pin wheel transmission device 39 and pin tooth 8 can mate and obtain steering handwheel input end to mouth, input end of motor to the different gear ratio value of mouth.

As seen through the above analysis, the active steering system of vehicle of described employing cycloidal-pin wheel mechanism can be realized active steering.Newly-increased degree of freedom by electric machine control can provide the deflection angle of a stack to deflector, during electrical fault, magnetic clutch disconnects automatically, guarantees that now bearing circle can, directly to deflector input, be controlled motor turning.For steering swivel system, a kind of novel, failure-free, compact steering swivel system scheme have been proposed.
