Detailed description of the invention
Describe the technical solution of the utility model in detail below by way of specific embodiment, following embodiment is only exemplary, only can be used for explaining and the technical solution of the utility model being described, and can not be interpreted as being the restriction to technical solutions of the utility model.
Embodiment 1
The utility model provides a kind of electric automotive steering column, as shown in Figures 4 to 6, includes steering column 103, output shaft 101 and bearing 102; The steering column connecting portion 1032 that described steering column 103 includes steering column body 1031 and is fixedly connected with described steering column body 1031 upper end;
Lower end and the deflector of described steering column body 1031 are rotationally connected; Described steering column connecting portion 1032 is tubular-shaped structures; Described bearing 102 is fixedly installed on in described steering column connecting portion 1032; The external diameter of described steering column connecting portion 1032 is greater than the external diameter of described steering column body 1031.
One end of described output shaft 101 is inserted in described bearing 102, and described output shaft 101 and described bearing 102 relatively rotate;
The sidewall inserting described bearing 102 part at described output shaft 101 is provided with at least one circle radial groove 104, in described groove 104, is provided with O type circle 105.The degree of depth of described groove 104 is less than the thickness of described O type circle 105.The external diameter of described O type circle 105 is greater than the external diameter of described output shaft 101.Can make like this after O type circle 105 is enclosed within groove 104, can some to be exposed, be used for the friction of buffer output shaft 101 and bearing 102.In the present embodiment, the axial cross section of described groove 104 is trapezoidal; The described shape of O type circle 105 and the matching form of described groove 104 close.In other enforcement of the application, the cross sectional shape of groove 104 can be square or other shape.
Embodiment 2
The utility model provides a kind of electric automotive steering column, include steering column, output shaft and bearing; The steering column connecting portion that described steering column includes steering column body and is fixedly connected with described steering column body upper end;
