Among the figure, 1. axis, 2. first bevel gear, 3. input shaft, 4. in pedestal; 5. spring, 6. second bevel gear, 7. bogie, 8. output shaft, 9. third hand tap gear; 10. sleeve, suspension on 11., 12. lower suspensions, 13. steering linkagess; 14. vertical plate, 15. first transverse plates, 16. second transverse plates, 17. long strip grooves.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
As shown in Figure 1, the utility model provides a kind of wheel limit differential attachment that is applied to the wide-angle wheel steering, comprises axis 1, sleeve 10, input shaft 3 and output shaft 8; Axis 1 sky is enclosed within the sleeve 10, can be in sleeve 10 along Z to moving; Sleeve 10 outer surfaces are fixed with middle pedestal 4, and the outer surface of sleeve 10 also is provided with bogie 7, are provided with bearing between bogie 7 and sleeve 10 outer surfaces, and bogie 7 can rotate with respect to sleeve 10; Input shaft 3 passes middle pedestal 4, and and middle pedestal 4 between be provided with bearing, the end of input shaft 3 is fixed with first bevel gear 2; The outer surface of sleeve 10 is provided with second bevel gear, 6, the second bevel gears 6 through bearing and first bevel gear 2 is meshing with each other; Output shaft 8 pass bogie 7 and and bogie 7 between be provided with bearing, the end of output shaft 8 is fixed with third hand tap gear 9, the third hand tap gear 9 and second bevel gear 6 are meshing with each other.The tapering of first bevel gear 2, second bevel gear 6 and third hand tap gear 9 is 45 °, and engagement forms differential in twos.Axis 1 top also is provided with spring 5, and sleeve 10 receives spring pressure, makes entire mechanism produce the effect of shock-absorbing.
The working principle of the utility model is that during transferring power, power is by input shaft 3 inputs; Driving first bevel gear 2 rotates; First bevel gear 2 drives second bevel gear 6 again and rotates, and second bevel gear 6 drives third hand tap gear 9 again and rotates, thereby makes power from output shaft 8 outputs.When turning to, the external world turns to driving force pulling bogie 7 to turn to around axis 1, makes bogie 7, third hand tap gear 9 and output shaft 8 integral body turn to around axis 1, and the third hand tap gear 9 and second bevel gear 6 still are meshing with each other when turning to, and relatively rotate; When the shock-absorbing motion takes place when, be arranged at middle pedestal 4 on the sleeve 10, bogie 7 and sleeve 10 as a whole mechanism at spring 5 effects generation shock-proof effect down.Both turning to, during transferring power, third hand tap gear 9 had both been born power transmission again, can under steering force, rotate around axis 1 again, and relatively rotated under second bevel gear, the 6 engagement situation.
The utility model is taken turns the limit differential attachment to be applied on the model car; As shown in Figure 2; The upper end of axis 1 is fixed on the suspension 11, also is provided with lower suspension 12 on the axis 1, and lower suspension 12 is made up of vertical plate 14, first transverse plate 15 and second transverse plate 16; First transverse plate 15 and second transverse plate 16 are arranged on the two ends of vertical plate 14, and lay respectively at the both sides of vertical plate 14.The lower end of axis 1 is fixed on second transverse plate 16, and vertically plate 14 is provided with long strip groove 17.Last suspension 11 is fixed on the model car with lower suspension 12, and the two ends of axis 1 are fixed through second transverse plate 16 of last suspension 11 and lower suspension 12, and spring 5 is enclosed within on the axis 1 between suspension 11 and the bogie 7, forms independent suspension system with sleeve mechanism.Input shaft 3 passes the long strip groove 17 on vertical plate 14, when the shock-absorbing motion takes place, input shaft 3 in long strip groove 17 along with whole mechanism moves up and down.In the outer vertical surface of pedestal 4 fit with the vertical internal surface of plate 14, when the shock-absorbing motion took place, 4 of middle pedestals vertically moved with respect to vertical plate 14.Third hand tap gear 9 and output shaft 8 (output wheel) relative fixed can carry out power transmission; Be fixed with steering linkages 13 on the bogie 7,, can make the third hand tap gear 9, bogie 7 and the output shaft 8 (output wheel) that mesh with second bevel gear 6 carry out divertical motion around axis 1 as steering equipment when extraneous steering force acts on the steering linkages 13.During transferring power, power is from input shaft 3 input, and through first bevel gear 2, second bevel gear 6, third hand tap gear 9 transferring power, power is at last by output shaft 8 outputs successively.When carrying out divertical motion, steering linkages 13 receives horizontal pull, makes bogie 7, third hand tap gear 9 and output shaft 8 (output wheel) rotate with respect to sleeve 10, promptly rotates around axis 1.When shock-absorbing is moved; The stressed motion straight up of output shaft 8 (output wheel); Make output shaft 8 (output wheel), bogie 7, middle pedestal 4, first bevel gear 2, second bevel gear 6, third hand tap gear 9, sleeve 10 and input shaft 3 as a whole shockproof mechanism move upward along axis; Thereby the shock-absorbing motion takes place in pressure spring 5.
