Anti-rollover body mechanism of multi-wheel truck

Abstract

The invention discloses an anti-rollover body mechanism of a multi-wheel truck, comprising a truck frame, wherein, a truck box and at least three wheels are arranged on the truck frame, two wheels constitute two adjusting wheels, and the two adjusting wheels are connected with the truck frame and the truck box through a linkage adjusting mechanism. The linkage adjusting mechanism comprises at least two upper crossbars, a middle connecting shaft is arranged in the middle of the upper crossbar, and a side connecting shaft is arranged at the end of the upper crossbar. Each central connecting shaft is pivotally connected with a central connecting frame, and the same side connecting shaft is pivotally connected with one side connecting frame. The middle connecting frame is fixedly connected with the vehicle frame. A lateral connecting frame and a bottom of a middle connecting frame are connected into an integral structure through a lower cross bar. The middle and rear parts of the side connecting frame are pivotally connected with a connecting arm through a transverse connecting shaft, and the rear part of the connecting arm is connected with the adjusting wheel. The two adjusting wheels designed by the invention can be adjusted in position and height with respect to the load box in the turning process, so as to effectively reduce the centrifugal force influence on the vehicle bodywhen turning, and ensure the turning to be stable.

Description

technical field [0001] The invention relates to a three-wheel or more than three-wheel motorized or electric carrier, in particular to an anti-rollover body mechanism of a multi-wheel carrier. Background technique [0002] In the design of the existing three-wheel or more motorized or electric cargo vehicles (including express delivery vehicles, mopeds for the elderly, etc.), for the sake of driving stability and manufacturing economy, the body directly adopts a full load-bearing structure, although straight-line driving It is stable, but the driving wheels in this body structure will not be adjusted relative to the frame. It has a large body shape, and the body is prone to tilt due to centrifugal force when turning, especially when the speed is too fast, it is very easy to roll over. There are great security risks. Contents of the invention [0003] In view of the above-mentioned problems, the present invention designs an anti-rollover body mechanism of a multi-wheel car...
