Anti-loosening device for balanced suspension thrust rod

Abstract

The invention relates to an anti-loosening device for a balanced suspension thrust rod, and relates to the field of balanced suspension equipment structures. A first anti-loosening assembly on the anti-loosening device is used for being arranged at the end part of one end of a balanced suspension, and specifically comprises a first connecting part and second connecting parts arranged on the two sides of the first connecting part correspondingly. The first connecting part is used for being connected with a thrust rod; at least one first fastener is arranged on each second connecting part; two groups of second anti-loosening assemblies are used for respectively and sequentially penetrating through one side of the balanced suspension and the corresponding second connecting parts in order to make the second connecting parts connected and fixed to the balanced suspension; at least one second fastener detachably connected with the first fastener is arranged at the end, close to the corresponding second connecting part, of each second anti-loosening assembly; and the second anti-loosening assemblies are mainly used for limiting relative movement of the second anti-loosening assemblies andthe second connecting parts after the second anti-loosening assemblies and the second connecting parts are fixed. The anti-loosening device solves the problems that in the prior art, a bolt connecting structure is poor in anti-loosening effect, and meanwhile the thrust rod is difficult to install due to the structure of the bolt connecting structure.

Description

technical field [0001] The present application relates to the structural field of balance suspension equipment, in particular to an anti-loosening device for a balance suspension thrust rod. Background technique [0002] At present, in order to improve transportation efficiency and reduce the cost of logistics, heavy-duty trucks have achieved rapid development in China. In order to strive for greater load capacity while not subjecting the rear bearings to excessive loads and reduce the grounding pressure of the rear wheels, the current heavy-duty trucks Trucks are all multi-axle. When a multi-axle heavy-duty truck is driving on an uneven road, the wheels may hang in the air and the vertical load of each wheel is uneven. In order to solve this problem, a balanced suspension structure is usually set on the multi-axle car. Avoid the phenomenon that the wheels are suspended in the air and the vertical loads of the two axles are not equal. [0003] The balance suspension of hea...
