Problems solved by technology

Due to the large mass of tricycles, especially truck tricycles, the front fork composed of symmetrical fixed fork legs is often difficult to withstand the impact during driving, causing deformation and damage of the fork legs, and even affecting the driver's life safety
Therefore, the existing single-leg front fork does not meet the load-bearing requirements of the tricycle in terms of strength and shock absorption, and there is a relatively serious potential safety hazard.
[0003] Through searching, no published patent documents identical or similar to this patent application have been found

Embodiment 1

[0022] Embodiment 1: see figure 1 , 2 , 3.

[0023] A front fork with two legs of a tricycle, comprising a fork standpipe 1, a fork shoulder 4, a fork leg and a fork hook 7, the fork standpipe is fixed on the upper plane of the fork shoulder, and two symmetrical forks are fixed on the lower plane of the fork shoulder Legs are equipped with fork hooks at the lower end of each fork leg. The innovation of the present invention is that the fork legs fixed on the lower plane of the fork shoulder are two pairs of front and rear, the four fork legs are evenly distributed and fixed on the lower plane of the fork shoulder, and the fork riser is fixed on the upper plane of the fork shoulder center of. The specific structure is:

[0024] 1. The fork standpipe is fixed in the middle of the upper plane of the fork shoulder, and the four inner fork legs 3 are fixed and evenly distributed on the lower plane of the fork shoulder with the fork riser as the axis, and the lower part of each ...

Embodiment 2

[0028] Example 2: see Figure 4 .

[0029] The difference from Embodiment 1 is only that the shock absorbing spring is installed on the inner fork leg between the inner fork leg and the outer fork leg, and the shock absorbing spring installed in the outer fork leg is omitted.

[0030] The fixing method not described in detail in the present invention is generally welding fixing, and engaging fixing can also be used.

Abstract

The invention relates to a bi-leg front fork of a tricycle, which comprises a plurality of fork stand pipes, a plurality of fork shoulders, a plurality of fork legs and a plurality of fork hooks, wherein the upper planes of the fork shoulders are fixedly provided with the fork stand pipes; the lower planes of the fork shoulders are fixedly provided with two symmetrical fork legs; the lower end of each fork leg is fixedly provided with the fork hook; the back of each fork leg which is fixedly arranged at the lower plane of each fork arm is further fixedly provided with a pair of fork legs, so that the fork legs form into two pairs at the front and the back; the four fork legs are evenly distributed and fixedly arranged at the lower planes of the fork shoulders; and the fork stand pipes are fixedly arranged at the center of the upper planes of the fork arms. The bi-leg front fork is further fixedly provided with another front fork based on the original mono-leg front fork to form the bi-leg front fork, so that the intensity and the rigidity of the front fork can be greatly enhanced, and the resistance strength of the horizontal impact generated in the running can be improved; and simultaneously, as a pair of damping springs is additionally arranged on the bi-leg front fork, the damping performance of the tricycle can be improved, and the comfortable sensation of the driver can be correspondingly increased.

Description

technical field [0001] The invention relates to a tricycle, in particular to a front fork with two legs of a tricycle. Background technique [0002] At present, tricycles, especially electric tricycles, are the main means of transport for manpower, and have the characteristics of large load capacity and flexible maneuverability. Because tricycles, especially truck tricycles, have a high quality, the front forks formed by the symmetrical fixed fork legs are often difficult to withstand the impact during driving, causing the fork legs to be deformed and damaged, and even affect the safety of the driver. Therefore, the existing single-leg front fork cannot meet the loading requirements of the tricycle in aspects such as strength and shock absorption, and there is a relatively serious potential safety hazard. [0003] Through searching, no published patent documents identical or similar to this patent application have been found. Contents of the invention [0004] The purpos...
