Problems solved by technology
Since there is only one front wheel deflection, and in order to ensure the turning stability of the sweeper, the deflection angle of the front wheel should not be too large, which determines that the sweeper has a large turning radius and low maneuverability and flexibility.

Embodiment Construction
[0016] like figure 1 , 2 As shown, the three-wheel linkage steering mechanism of the three-wheel electric sweeper of the present invention is composed of a front wheel steering chain transmission mechanism, a rear wheel steering chain transmission mechanism and two sets of identical hinge four-bar mechanisms:
[0017] The said front wheel steering chain transmission mechanism is composed of front wheel steering small sprocket (1), front wheel steering large sprocket (3), front wheel steering tensioning sprocket (4) and front wheel steering small sprocket (1) and the front wheel steering chain (2) moving between the front wheel steering large sprocket (3), the movement of the front wheel steering small sprocket (1) comes from the steering wheel, and the front wheel steering chain (2) The transmission plays the role of deceleration.
[0018] The said rear wheel steering chain transmission mechanism consists of the rear wheel steering small sprocket (11), the rear wheel steerin...

The invention provides a three-wheel linkage steering mechanism of a three-wheel electric sweeper. The three-wheel linkage steering mechanism is composed of a front wheel steering chain transmission mechanism, a rear wheel steering chain transmission mechanism and two sets of identical hinge four-rod mechanisms. The three-wheel linkage steering mechanism of the three-wheel electric sweeper has the following advantages that rear wheel steering chain transmission and the two identical hinge four-rod mechanism sets are adopted for achieving linkage of front wheel deflection and the deflection of two rear wheels, and therefore the turning radius in the steering process of the sweeper is reduced, and the steering flexibility of the sweeper is improved; the rod length of the hinge four-rod mechanisms is reasonably set, the rotary axes of the three wheels cross at one point in a short-sighted mode, approximate pure rolling between the three wheels and the ground is achieved, and therefore sliding resistance and sliding abrasion between rims and the ground are reduced; speed reduction transmission is adopted by rear wheel steering chain transmission, the rear wheel deflection angle is smaller than the front wheel deflection angle in the steering process, the instantaneous rotation center of the sweeper is deflected to the rear portion of the sweeper in the steering process, and steering stability can be improved.
Description
technical field [0001] The invention relates to a three-wheel electric sweeper, in particular to a three-wheel linkage steering mechanism of the three-wheel electric sweeper. Background technique [0002] For a three-wheeled electric sweeper with one front wheel and two rear wheels, the front wheel deflection method is currently used to realize the function of turning. Since there is only one front wheel deflection, and in order to ensure the turning stability of the sweeper, the deflection angle of the front wheel should not be too large, which determines that the sweeper has a large turning radius and low maneuverability and flexibility. [0003] Therefore, it is necessary to provide a three-wheel linkage steering mechanism that can make the three wheels of the three-wheel electric sweeper deflect in linkage, thereby reducing the turning radius and improving driving flexibility. Contents of the invention [0004] The object of the present invention is to overcome the di...
