The specific embodiment
With reference to Figure of description, New-energy electric vehicle steering hardware of the present utility model is described in detail below.
As shown in Figure 1 and Figure 2, New-energy electric vehicle steering hardware of the present utility model, its structure comprises bearing circle 1, steering hub column 2, steering wheel 3, steering track rod and wheel 11, described bearing circle 1 is connected with steering wheel 3 is inner by steering hub column 2, steering wheel 3 bottoms are connected with steering wheel lower shaft 4, steering wheel lower shaft 4 rotates around steering wheel 3 axis, described steering wheel lower shaft 4 bottoms are connected with pitman arm, described pitman arm is connected with steering track rod by bulb 9, and the free end of steering track rod is by turning to goat's horn 10 to connect wheel 11.
As shown in Figure 2 and Figure 3, described pitman arm comprises power arm 5 and labor saving arm 6, described power arm 5 length are greater than the length of labor saving arm 6, pass through lever principle, give 5 one little power of power arm, labor saving arm 6 will obtain a large power and drive steering track rod to turn to, so steering wheel rotation 1 easily just can labour-saving be realized the rotation of wheel 11.Power arm 5 is connected by bolts and nuts with the coupling end of steering wheel lower shaft 4, between the contact surface being connected, is provided with slipmat 13 at power arm 5 with steering wheel lower shaft 4.Slipmat 13 can adopt nylon material, prevents that power arm 5 from directly contacting with steering wheel lower shaft 4, reduces friction, guarantees accuracy rate, also can extend the service life of each parts simultaneously.
Described bulb 9 tops are provided with the axle of back taper, and the upper end of labor saving arm 6 is connected with power arm 5, and inside, lower end is provided with the cone tank with taper shaft 91 interference fit; By taper shaft 91, be connected, install simple, load-carrying capacity is large, the load that withstands shocks and variable load performance good, can improve connection transmitting torque, guaranteed the working stability of steering hardware.
