As in Figure 2-4, it is shown that the steering wheel of embodiment one of the present utility model.Fig. 2 is the front view of the steering wheel of embodiment one, and Fig. 3 is the left view of the steering wheel of embodiment one, Fig. 4 a and steering wheel that Fig. 4 b is embodiment one front view when rotation status.
As in Figure 2-4, the steering wheel of embodiment one, described steering wheel includes:
Shell, described shell includes drive end bearing bracket 501, main body 1 and rear end cap 502, drive end bearing bracket 501, main body 1 and rear end cap 502 link together, connected mode can be, as in figure 2 it is shown, connected by screw 8 and screw hole on drive end bearing bracket 501 and rear end cap 502 is counterbore so that screw terminal does not protrude from the surface of forward and backward end cap, it is of course also possible to select to be connected together, the conventional alternative such as bonding is attached；
Wherein, drive end bearing bracket 501 is provided with the output shaft hole passed for steering wheel output shaft 7.
Wherein, main body 1 includes that top 2, described top 2 include that a planar portions 201 and two curved portions 202, two curved portions 202 link together with left part 601 and right part 602 respectively.
As Figure 2-3, the outer contour shape of the cross section at the top of described drive end bearing bracket 501 and the top of described rear end cap 502 all outer contour shapes with the cross section at the top 2 of described main body 1 are identical, preferably, the outer contour shape of drive end bearing bracket 501 and rear end cap 502 cross section is identical with the outer contour shape of main body 1 cross section.
Main body 1 also includes that left part 601, right part 602 and bottom 4, described top 2, left part 601, right part 602 and bottom 4 connect into an entirety, it is preferable that can be to be bonded together or integrated.
Preferably, connection between planar portions 201 and curved portions 202 and two curved portions 202 be connected with between left part 601, right part 602 be all smooth, there is no the connection of burr.
As Figure 2-3, connector 3 includes connecting flat board 301, front connection end plate 302 and rear connection end plate 303, preferably, front connection end plate 302 and rear connection end plate 303 are parallel to each other and both perpendicular to connecting flat board 301, and the length extended along the direction being perpendicular to connection flat board 301 of front connection end plate 302 and rear connection end plate 303 is equal, certainly, the shape and structure of front connection end plate 302 and rear connection end plate 303 is also designed to identical.
