The rolling bearing inner ring fixed plate is circular, and size is big or small consistent with the rolling bearing inner ring external diameter, and an aperture is opened at the center, and after screw passed and is screwed into pillar top nut bore behind the aperture, plaing a part fixedly, antifriction-bearing box did not move up and down.

The effect of antifriction-bearing box is to make the shell of rolling disc when stressed steering wheel rotation, do not changed with the rotation direction of bearing circle by force direction, and reduces and rotate friction.Fixed groove of the inside face of rolling bearing inner ring excavation, the big or small degree of depth is consistent with the fixed strip of pillar epimere, and purpose is the inner ring of fixedly antifriction-bearing box and do not allow itself and outer ring together rotate.The outer ring excavation nut aperture of antifriction-bearing box, little hole count is consistent with the aperture number of rolling disc shell, purpose is to allow the shell of rolling disc after being inserted in antifriction-bearing box outside, and available screw is screwed into outer ring nut aperture by the aperture of shell, reaches the effect that shell and housing washer are fixed.

The shell of rolling disc, it is hollow cylinder with a bottom surface, be flat colyliform, the shell inner cavity size is identical with the housing washer diameter or bigger, the height of shell is consistent with the antifriction-bearing box height, the bottom surface of shell is gently to outer lug, and the one, feel comfortable when making the palm of the hand pin it, the 2nd, for fear of contacting with the rolling bearing inner ring fixed plate.Aperture is opened in the shell side, and the position of aperture is corresponding with the nut aperture of outside race with quantity, and purpose is by aperture shell and housing washer to be fixed.

The diameter of whole rolling disc is to be advisable above steering wheel rim diameter under the normal operating condition slightly, highly (thickness) palm part beyond the centre of the palm is not obvious when pushing down rolling disc with the centre of the palm contacts with steering wheel rim and friction is advisable, rolling disc is flat colyliform, and rolling disc is connected steering wheel rim with fixed form.Rolling disc places the vertex of bearing circle under the self-propelled vehicle straight-line travelling state, the most proximal end of the motor-car Windshield of disembarking, it is away from driver's position, front, also destruction direction dish both sides weight balancing not during the self-propelled vehicle straight-line travelling, and when turning to convenient the use.

The beneficial effect of the invention is, at motor turning or sail into, when rolling the parking stall away from, the driver can carry out transforming gear or other operations with a hand, the another palm of the hand is according to the turn disc bearing circle of bearing circle, can realize turning to of bearing circle incessantly, swimmingly, palm need not change with the bearing circle direction, uses laborsaving, convenient, do not influence the use of other design functions of bearing circle, the driver is not brought potential safety hazard.
