Problems solved by technology

[0003] In the reverse tricycle of the prior art, in order to make the front steering wheel train comprising two wheels adapt to the complex terrain environment, so that the left and right wheels will not tilt the car body when the height of the ground in contact with the left and right wheels is inconsistent, generally all adopt Let the left wheel and the right wheel be supported on the left and right ends of the rocker through four front shock absorbers. This way makes the front shock absorber subject to a large lateral component force, which is prone to failure and poses a safety hazard.
At the same time, in the reverse tricycle of the prior art, the main moving structural parts are scattered in the steering sleeve and the suspension system, the center of gravity is high and the motion transmission is not direct. On the steering column sleeve above the frame, the steering column sleeve is a hollow part, which is also an unsafe factor
Simultaneously the main frame structure and processing procedure of prior art are all relatively complicated, and intensity is not enough

Embodiment 1

[0058] The universal steering mechanism of embodiment one such as Figure 8 As shown, it includes a left tie rod 404 and a right tie rod 405, and the two ends of the left tie rod 404 and the right tie rod 405 are respectively provided with rod end joint bearings;

[0059] The inner ring body 901 of the rod end joint bearing at the inner end of the left tie rod 404 is fixedly connected to the inner ring body 902 of the rod end joint bearing at the inner end of the right tie rod 405; the left tie rod 404 is connected through the inner ring body 903 of the rod end joint bearing at its outer end The left steering knuckle structure 203, the right tie rod 405 is connected to the right steering knuckle structure 303 through the inner ring body 904 of the rod end joint bearing at its outer end; The center hole of the inner ring body 901 of the rod end joint bearing at the inner end of the left tie rod 404 is also connected to the bottom end of the front steering column 401 . The inst...

Embodiment 2

[0061] The universal steering mechanism of embodiment two such as Figure 9 As shown, it includes a cross shaft 403, a left connecting rod 404, and a right connecting rod 405. The lower end of the front steering column 401 is hinged to the first shaft portion of the cross shaft 403, and the second shaft portion of the cross shaft 403 is connected to the The left connecting rod 404 and the right connecting rod 405 are hinged, the left connecting rod 404 connects the left steering knuckle structure 203 and the cross shaft 403, and the right connecting rod 405 connects the right steering knuckle structure 303 and the cross shaft 403. Describe the cross shaft 403. The left steering knuckle structure 203 and the left connecting rod 404 are also connected through a cross shaft, and the right steering knuckle structure 303 and the right connecting rod 405 are also connected through a cross shaft.

[0062] In the first embodiment, the main frame 1 includes a front bracket 102 and a m...

Abstract

The invention provides a reverse tricycle. The reverse tricycle is characterized by comprising a deflection and steering mechanism, a rear-section frame, a driving wheel and two front wheels; the deflection and steering mechanism is arranged at the front end of the rear-section frame, the two front wheels are connected with the deflection and steering mechanism and symmetrically arranged on the left side and the right side of the front end of the rear-section frame with the rear-section frame as the axis of symmetry, and the driving wheel is arranged at the rear end of the rear-section frame. By the adoption of the technical scheme, a left rocking arm and a right rocking arm are coaxially hinged to a main frame, in the turning or inclining process, full parallelism can be achieved, the tricycle is driven more stably, and the left rocking arm and the right rocking arm are independent non-interference gravity center deflection systems; meanwhile, through the structure of a single shock absorber, the production cost of the reverse tricycle is greatly reduced.

Description

technical field [0001] The invention relates to a reverse tricycle structure. Background technique [0002] The so-called reverse tricycle refers to a relatively special product whose front steering wheel system includes two wheels. Compared with the two-wheeled vehicle, one more wheel is in contact with the ground. The stability advantage greatly reduces the possibility of the rider slipping and falling, and the driving safety is greatly improved compared with the two-wheeled vehicle in the complex terrain environment. [0003] In the reverse tricycle of the prior art, in order to make the front steering wheel train comprising two wheels adapt to the complex terrain environment, so that the left and right wheels will not tilt the car body when the height of the ground in contact with the left and right wheels is inconsistent, generally all adopt Let the left wheel and the right wheel be supported on the left and right ends of the rocker through four front shock absorbers. ...
