The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, the ball cardan wheel of stopping has support 1, wheel 2 is fixed on support 1 lower end, be arranged with taper shank 5 in the bearing 3, be arranged with bearing outsourcing circle 4 outside the bearing 3, and the circular hole (not shown) flange riveted on support 1 top passed on support 1 top in bearing outsourcing circle 4 lower ends 41.Bearing 3 and bearing outsourcing circle 4 all place in the guard shield 6, and guard shield 6 is fixed on by connecting element on the boss 51 of taper shank 5, have 61,62, two through holes 61,62 of two grooves on these guard shield 6 sidewalls and are symmetricly set on guard shield 6 sidewalls.The utility model further groove also can adopt through hole, and just groove can be with the moulding of guard shield one-off drawing, and through hole need increase drilling process, considers that the comfort feature in the practical operation just adopts groove.Brake gear 20 is fixed on the support 1, and brake gear 20 has the top 9 of energy axial motion, and the spherical end surface of top 9 partly is resisted against in one of them groove 61,62 of guard shield 6.
Described brake gear 20 comprises shell 10, setting nut 7, spring 8 and has the top 9 of spherical end surface, shell 10 is fixed on the support 1 by connecting element, setting nut 7, spring 8 and come directly towards 9 and all be arranged in the shell 10, wherein setting nut 7 is established into shell 10 from a port spiral shell of shell 10, the other port of shell 10 is provided with top 9, it is provided with the maximum gauge of the port internal diameter of top 9 less than top 9, spring 8 is between setting nut 7 tops 9, and respectively with both mutual contacts, and will come directly towards 9 contacts to shell 10 ports.The maximum gauge of described top 9 is less than the internal diameter of shell 10.The internal diameter of spring 8 is less than the maximum gauge of top 9, and the while is less than the diameter of setting nut 7.
During use, do not need to change working direction only during straight ahead in go-cart, at this moment the spherical end surface of top 9 places in the groove 61 of guard shield 6 in the brake gear 20, because the contact of 8 pairs of tops 9 of spring produces certain pressure, therefore can not come out in groove 61 in top 9 under not having the situation of external force, and then wheel 2 can not freely rotate.When go-cart needs the conversion working direction, go-cart is that the strong point rotates with wheel 2 with ground-surface contact point, and this moment, wheel 2 did not rotate, because wheel 2 is fixed together with support 1, support 1 is fixed together with brake gear 20 again, so support 1 and brake gear 20 do not rotate yet.And taper shank 5 can be around axle with rotating, because guard shield 6 is fixed together with taper shank 5, taper shank 5 drives guard shield 6 and rotates together.Guard shield 6 produces certain torsional forces when rotating, when pressure that this torsional forces produces greater than the contact of 8 pairs on spring top 9, sliding from groove 61 in top 9, and slides along guard shield 6 walls in groove 61 part in addition, drives brake gear 20, support 1 and wheel 2 and rotate.After wheel 2 forwarded assigned direction to, groove 62 went to 9 places, top, and top 9 is placed in the groove 62, and this moment, support 1 can not rotate around axle, and promptly wheel 2 can not rotate, and can only move ahead along rectilinear direction.The size of torsional forces can be regulated according to actual needs, thereby the adjusting of the pressure by 7 pairs of springs 8 of governing screw is to the adjusting of torsional forces size.
The utility model utilizes the principle of moment of torsion mechanics, wheel direction changes when torsional forces surpasses setting value, the wheel direction only straight ahead that do not change when not surpassing setting value, make cardan wheel can not only freely change working direction, and when not needing to turn, can check direction, cardan wheel is only advanced along rectilinear direction, and this torsional forces can also be regulated as required voluntarily simultaneously, has made things convenient for user's use.
