Steering mechanism of power car

Abstract

The invention discloses a steering mechanism of a power car, which comprises a main shaft, a car frame, a steering yoke, a steering seat, a thrust bearing upper seat, a thrust bearing lower seat, a big sprocket wheel, a small sprocket wheel, a drive shaft and a transitional block. The upper end of the steering yoke is provided with a steering wheel; the lower end of the steering yoke is provided with a hub motor; a universal joint is arranged between the steering yoke and the hub motor; a conical roller bearing outer ring is arranged in a hole in the thrust bearing upper seat; a thrust cylindrical roller bearing is arranged between the thrust bearing upper seat and the thrust bearing lower seat; a conical roller bearing inner ring and flat washers are sequentially sleeved between the mainshaft and the thrust bearing upper seat; and the main shaft is fixed with the thrust bearing upper seat through a hexagonal slotted nut. By using the steering mechanism of the power car, the defects of fewer steering strokes, small steering angle range, low utilization rate of the internal space of a car body and the like in the prior art can be overcome, so as to achieve the advantages of more steering strokes, large steering angle range and high utilization rate of the internal space of the car body.

Description

technical field [0001] The invention relates to a power vehicle, in particular to a steering mechanism of a power vehicle. Background technique [0002] At present, the steering mode of the power car is various, such as: the wheel of the power car is fixed on the front fork, the head pipe is fixed on the vehicle frame, a tapered roller bearing is installed between the shaft on the front fork and the head pipe, and a large nut shaft is used to In this way, the front fork can only be rotated, and a handle is installed on the top of the front fork. When the handle is rotated, the front fork rotates, so that the front wheel can be rotated. [0003] For another example, the front wheel of the power car is fixed on the front fork, and the head pipe is fixed on the frame. Tapered roller bearings are installed between the shaft on the front fork and the head pipe, and are axially fixed with nuts, and then installed on the fan-shaped inner The teeth are fixed with nuts; the steering...

AI Technical Summary

Problems solved by technology

[0005] (1) Less steering stroke: when the power vehicle is turning and driving, it needs to drive the wheel to rotate directly through the rotation of the shaft, and then use the limit block to realize the limit of the rotation angle, but the steering stroke is too small;

[0006] (2) The steering angle range is small: when the power vehicle is turning and driving, the steering is realized through the combination of gears and sector gears, but the steering angle is limited;

[0007] (3) Low utilization rate of the internal space of the vehicle body: the power vehicle adopts rear wheel drive when steering and driving, but the utilization rate of the internal space of the vehicle body is low
