Embodiment Construction
[0024] The present invention is described in detail below in conjunction with accompanying drawing:
[0025] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, a hyperboloid V-shaped circular arc slot power transmission turntable includes a rotary shaft (11) located in the middle of the bottom, a process counterbore (1) and a center of the upper surface for clamping and placing bicycles. The hyperboloid V-shaped circular arc draw-in groove (3) of the front tire, the middle cross-section (9) of the described hyperboloid V-shaped circular arc draw-in groove (3) is V-shaped, and the angle of its V-shaped angle is 112°- 146°.
[0026] The groove end cross-section 2 of the hyperboloid V-shaped circular arc clamping groove 3 is also designed to be V-shaped, and the included angle of the V-shaped is 85°-116°.
[0027] The V-shaped included angle of the hyperboloid V-shaped circular arc slot 3 is a small angle gradual...

The invention relates to a double curved surface V-type arc neck force transferring rotary table, comprising a rotating shaft (11), a double curved surface V-type arc neck (3), a positioning step round (8) and six small screw holes (15) uniformly distributed in the step round as well as technological counter bored holes (1) formed at the upper end of each small screw hole. The double curved surface V-type arc neck is characterized in that a V-type angle of the cross section at the middle part of the neck is 112-146 degrees and the V-type angles of the cross sections at the two ends of the neck are 85-116 degrees; and the V-type angles of the cross sections of the neck are characterized in that the angles of sections at different positions are different in dimension, namely the angles are gradually changed from the middle part of the neck to the two ends of the neck. The length of the neck is 88-156mm, the radius of arc on a transverse section at the bottom of the neck is 8-15mm, and the radius of arc on a longitudinal section at the bottom of the neck is 272-355mm. By adopting the structure, clamping is stable without slip when the double curved surface V-type arc neck is matched with the cover tyres of front wheels of bicycles of all specifications and sizes.
Description
(1) Technical field [0001] The invention relates to a hyperboloid V-shaped arc slot power transmission turntable, in particular to a hyperboloid V-shaped arc slot power transmission turntable for a bicycle riding balance simulation device for riding a bicycle on the spot. (2) Background technology [0002] As we all know, people control the balance by swinging the bicycle handle when riding a bicycle, and by changing the riding track of the bicycle (the position of the bicycle changes left and right with the rotation of the handlebar) so as to achieve the purpose of controlling the riding balance. The bicycle riding balance simulation device is just to simulate this principle. When people ride a bicycle on the bicycle riding balance simulation device, the front wheel of the bicycle does not roll on the ground but is placed on the power transmission dial on the bicycle riding balance simulation device. In the circular arc groove, the circular arc groove transmits the left and...
