Embodiment 1
[0034] A road drift board. Such as figure 1 and figure 2 As shown, the road drift board includes a pedal 1 , a bracket 2 , a shock absorber 3 , a rear wheel set 4 and a front wheel set 5 . The front part and rear part of support 2 are equipped with front wheel set 5 and rear wheel set 4 correspondingly, and pedal 1 and damping plate 3 are fixed on the upper plane of support 2 successively by bolt from top to bottom.
[0035] Such as image 3 As shown, the rear wheel set 4 and the front wheel set 5 have the same structure, and both are composed of two axle sleeves 6, two bearings 7, rollers 8 and axles 9. Bearings 7 are installed symmetrically at both ends of the shaft hole of the roller 8 , the shaft 9 passes through the shaft hole and is installed in the two bearings 7 , and the shaft sleeve 6 is sleeved on both ends of the shaft 9 symmetrically. The rear wheel set 4 and the front wheel set 5 are installed in the corresponding rear mounting holes and front mounting holes...
Embodiment 2
[0045] A road drift board. Except following technical parameter, all the other are with embodiment 1:
[0046] Such as Figure 9 As shown, the wheel diameter of the roller 8 of the rear wheel group 4 and the front wheel group 5 is a combination of 97mm and 83mm, or a combination of 97mm and 72mm;
[0047] The pedal 1 is rectangular, the length of the rectangle is L=1.5-1.6A, and the width of the rectangle is B=1.3-1.4A;
[0048] The included angle α=15~16° between the center line of each row of mounting holes 11 and the center line of the rectangular plate;
[0049] The radius of curvature of the arc ρ=40-45mm;
[0050] The length ratio of left section arc: middle section arc: right section arc is 1:2.0~2.2:1.
[0051] Compared with the prior art, this specific embodiment has the following positive effects:
[0052] First, this specific embodiment adopts a large wheel diameter roller by improving the accommodability of the support 2 to the wheel diameter D of the roller 8...

Abstract
The invention relates to a road drift board. The road drift board is characterized in that a front wheel set 5 and a rear wheel set 4 are correspondingly arranged at the front part and the rear part of a support 2; a pedal 1 and a damping sheet 3 are sequentially fixed on the upper plane of the support 2 from top to bottom through a bolt; two rows of mounting holes 11 are formed in the central position of the pedal 1 in a mutual parallel manner; four mounting holes 11 are symmetrically arranged with the centroid of the pedal 1 as the center; an included angle alpha between a hole center connecting line of each row of mounting holes 11 and a center line of a rectangular board is 14 to 16 degrees; the support 2 is an integral formed by a flat plate and side plates which are symmetrically arranged on two sides of the flat plate; three groups of shaft holes are formed in the lower ends of the side plates; three groups of through holes 13 are formed in the flat plate of the support 2; threegroups of through holes 13 and the four through holes which can be simultaneously and correspondingly connected with in the pedal 1 are located in the same group. The road drift board disclosed by the invention has the characteristics of long service life, stable performance, high cruising ability and small physical consumption.
Description
technical field [0001] The invention belongs to the technical field of drift plates. In particular, it relates to a road drift board. Background technique [0002] Since the drift board was invented by American extreme sportsmen, it has quickly become popular all over the world because of its small size, light weight, strong fun, and strong skills. Although its design inspiration comes from four-wheel skateboards, it has already become an independent extreme sport since its development. [0003] With the continuous differentiation of the mainstream technology of the drift board, the disadvantages of the single type of the drift board are becoming more and more prominent. Due to the structural limitations of the drift board bracket, unlike some four-wheeled skateboards, rollers of any wheel diameter can be installed, so the maximum wheel diameter that the drift board can accommodate is one of the concerns of those skilled in the art. The existing drift board can accommodat...
