Problems solved by technology

Although the wheels of this wheel turning mechanism can realize large-angle steering, the structure of the wheel shaft transmission mechanism is complicated, and it needs to be driven by a generator. The manufacturing cost is high, the working noise is large, and the processing of the brake oil passage on the rotating positioning sleeve is difficult.

Embodiment Construction

[0020] As shown in the figure, the steering wheel driving device of the automobile has a mounting sleeve 5, an upper cover plate 7 is fixed by bolts on the upper end of the mounting sleeve 5, and a rotating positioning sleeve 1 is installed in the mounting sleeve 5 through two sets of bearings 3. The upper end of the positioning sleeve 1 is provided with a locking nut 6, and a supporting flange 2 is welded at the lower port of the corresponding mounting sleeve 5 on the outside of the rotating positioning sleeve 1, and a sealing ring is arranged between the supporting flange 2 and the mounting sleeve 5. The transmission between the installation sleeve 5 and the rotation positioning sleeve 1 is carried out through a transmission mechanism. The present embodiment of the transmission mechanism takes a worm transmission mechanism as an example. 4 and the worm gear 17 which is arranged on the rotating positioning sleeve 1 and meshes with the worm 4. The lower end of the rotation pos...

Abstract

The invention discloses a steering wheel driving device of a vehicle, which comprises a mounting sleeve, wherein a rotary positioning sleeve and an upper cover plate are arranged on the mounting sleeve; the mounting sleeve and the rotary positioning sleeve are driven by a driving mechanism; a shaft seat is fixed at the lower end of the rotary positioning sleeve; and a steering wheel is arranged on the shaft seat. The steering wheel driving device is characterized in that: a motor is arranged in the steering wheel; a rotary conductive device is arranged in the rotary positioning sleeve; a lead wire of the motor is led out through the rotary conductive device; a rotary oil delivery joint is arranged between the upper cover plate and the rotary positioning sleeve; and the oil inlet of the rotary oil delivery joint is connected with an oil inlet pipe, while the oil outlet is connected with a hydraulic brake through a brake oil pipe. The steering wheel driving device has the advantages that: the steering wheel can steer, also can be used as a driving wheel of the vehicle, and is simple in structure and low in work noise, and the steering wheel driving device can realize wide-angle steering of the steering wheel, so that the vehicle does not need to repeatedly steer when turning around and conveniently and quickly steer to turn around. The steering wheel driving device reduces the driving labor intensity of a driver.

Description

technical field [0001] In particular, the invention relates to a steering wheel drive device for an automobile. Background technique [0002] The existing wheel steering mechanisms of automobiles are all push-pull structures of transmission rods. The wheel steering can only rely on the support body to rotate at a small angle, but cannot rotate at a large angle or even 360 degrees. Poor flexibility increases the driver's driving labor intensity. [0003] The patent of invention with the publication number CN101323319 that I applied for discloses a wheel rotation mechanism. The wheels are connected and driven by the axle transmission mechanism. The outer positioning sleeve and the rotation positioning sleeve are connected through the transmission mechanism, and the outer positioning sleeve and the rotation positioning sleeve correspond to Equipped with brake oil passage. Although the wheels of this wheel turning mechanism can realize large-angle steering, the structure of th...
