Abstract

The utility model discloses a universal rotating frame which comprises a screw shaft, an upper cover, an upper bearing, a bearing sleeve, a lower bearing, a wheel frame, nuts and a force resistant device, wherein the screw shaft successively passes through every component and is tightly pressed by the nut. The utility model can make a universal wheel rotate directionally, and also push at quick speed or operate normally on the bumpy ground.

Description

A kind of universal swivel mount

Technical field

The utility model belongs to a kind of universal swivel mount that is applicable to that the control swivel turns to.

Background technology

Existing weaponry and equipment cardan wheel infrastructure product on the market, when in use working on ubiquity rapid movement or the scraggly road surface, exist cardan wheel because of crossing the violent dancing of pine: the front-wheel when walking as go-cart is acutely swung, make its direction, degree of balance, speed all be difficult to be controlled by the user, harm user's safety, the value of service of product itself is given full play to regard to difficulty.

Summary of the invention

The purpose of this utility model provides a kind of universal swivel mount that can control swivel rotation sensitivity.

The purpose of this utility model is achieved in that it comprises screw shaft, loam cake, head bearing, bearing carrier ring, lower bearing, wheel carrier, nut, and described screw shaft passes each parts successively and compressed by nut, also comprises resistance gauge.

The utility model is owing to the resistance gauge that is equipped with below loam cake or above the nut, pass through nut screwing clamping with each member on screw shaft, make the matrix of resistance gauge be pressed on head bearing inner ring or lower bearing inner ring or the wheel carrier, it is whole to constitute a rotating connection, wheel carrier and metal (upper are one and rotate whole, the rotation sensitivity of the relative screw shaft of wheel carrier is subjected to application force by the elasticity position of resistance gauge and control effectively like this, realizes that the existing direction of cardan wheel rotates normally operation on quick promotion or the rough and uneven in surface road is arranged again.The utility model is simple in structure, easy to assembly.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, embodiment 1 is made up of screw shaft 1, loam cake 2, resistance gauge 3, head bearing 4, bearing carrier ring 5, lower bearing 6, wheel carrier 7, nut 8.With reference to Fig. 4, resistance gauge 3 is matrixes 14, matrix 14 can be round or other solid such as square body or column, establish axis hole 15 in the matrix 14, its matrix 14 peripheries have resistance shell fragment 16, punching press forms on matrix 14 resistance shell fragment 16 1 tops and matrix 14 are one, and separate with matrix with inner side edge 18 on resistance shell fragment 16 another tops 17.Under the effect of external force, another top of resistance shell fragment and inner side edge and matrix are engagement state, remove external force, another top of resistance shell fragment and inner side edge and the separated attitude of matrix.Present embodiment is to be furnished with three resistance shell fragments around axis hole on matrix.Only need during assembling screw shaft 1 is passed loam cake 2, resistance gauge 3, head bearing 4, bearing carrier ring 5, lower bearing 6, wheel carrier 7 jam nut 8 then successively.The wheel hub of two forks of wheel carrier 7 bottoms of the universal swivel mount that installs and wheel 9 is taken turns sub-sleeve 11, a pair of packing ring 12, a nut 13 by a screw 1, to be connected.

Embodiment 2, and with reference to Fig. 1, Fig. 5, embodiment 2 is identical with embodiment 1 structure, and the matrix that is described resistance gauge 3 is between loam cake 2 and head bearing 4, and the other end of the resistance shell fragment 16 of resistance gauge places on the wheel carrier 7.

Embodiment 3, and with reference to Fig. 1, Fig. 6, embodiment 3 is identical with embodiment 1 structure, are that described resistance gauge 3 is between lower bearing 6 and nut 8.

Embodiment 4, with reference to Fig. 1, Fig. 7, Fig. 8, embodiment 4 is identical with embodiment 1 structure, be that described resistance gauge 3 is spring body, lay blind hole in wheel carrier 7 upper surfaces, resistance gauge 3 places between loam cake 2 and wheel carrier 7 blind holes, and spring one end of resistance gauge 3 withstands on the blind hole bottom surface that the loam cake inner spring one end spring other end places wheel carrier 7.

The utility model is not confined to above-mentioned fact Example; also can be according to the specification processing of the universal swivel mount of difference; the different materials processing and manufacturing; difformity machine-shaping; its structural principle technology can extend to every universal swivel mount that the rotation sensitivity of two relative swiveies is controlled, and its character all belongs to the present patent application protection domain.
