Novel wide-body mining hydro-pneumatic suspension double-vehicle rear axle device capable of avoiding loading difficulty

Abstract

The invention relates to the technical field of double rear axles and discloses a novel wide-body mining hydro-pneumatic suspension double-vehicle rear axle device capable of avoiding loading difficulty. The device comprises a hub, wherein a shell is connected to an outer side wall of the hub in a penetrating manner, a rotating wheel is connected to an inner side wall of the shell in a penetrating manner, and a connecting mechanism is connected to the inner side wall of the shell in a sliding manner; an end, away from the shell, of the connecting mechanism is connected with a main column in a penetrating mode, and an outer side wall of the main column is connected with a main bridge mechanism in a penetrating mode. a side wall of the butt-joint frame can obliquely approach the outer side wall of the butt-joint plate and cover the side wall of the butt-joint plate, at the moment, the inner side wall of the butt-joint frame and the butt-joint plate are attached to each other, and when the side wall of the butt-joint frame slides towards the outer end, the side wall of the main body column can be pulled to slide outwards, so the outer diameter size of the outer side wall of the connecting column is increased; the situation that the automobile is prone to breakage due to the fact that the weight exceeds the range can be avoided, the bearing capacity of the automobile can bear heavier objects, and the use requirement of the automobile is met.

Description

technical field [0001] The invention relates to the technical field of double rear axles, in particular to a novel wide-body mining oil-gas suspension double-vehicle rear axle device which avoids loading difficulties. Background technique [0002] Domestic mining vehicles are mainly divided into classic rigid mining dump trucks and wide-body mining vehicles. In comparison, wide-body mining vehicles have the advantages of low cost, cheap price, good versatility, and short production cycle. Good quality, short production cycle and other advantages, wide-body mining vehicles are mainly based on the technical route of road heavy trucks, due to the insufficient bearing capacity of the suspension system and the rear axle housing and the braking can not meet the mine road conditions and vehicle use, resulting in the existing Wide-body vehicles cannot carry heavy objects, and during use, the parts that carry the weight will break, which will affect the use.
