A hinge mechanism for articulated special vehicles

Abstract

An articulated mechanism for a special articulated vehicle, comprising a steering oil cylinder, a lateral adjustment oil cylinder, a telescopic oil cylinder, a pitch oil cylinder, a locking mechanism, a telescoping rod, a torsion seat, a connection seat, a steering hinge seat and a connection seat. The torsion seat and the connection seat are matched through the shaft hole, and the telescopic oil cylinder is driven to realize the longitudinal movement of the connection seat on the cylindrical slideway of the torsion seat, and the length of the hinge mechanism is adjusted; the connection seat is connected to the steering hinge seat with a pin shaft, and the steering movement is realized through the expansion and contraction of the steering cylinder. The horizontal position control of the hinge point of the steering cylinder and the telescopic cylinder can be realized through the horizontal adjustment cylinder, and the width of the hinge mechanism can be changed; through the cooperation of the locking mechanism and the telescopic rod, the lock of the hinge mechanism can be realized under the condition of constant rotation angle, and the steering mechanism can be enhanced. Rigidity; the steering hinged seat is connected with the pin shaft of the connecting seat, and the pitching motion is realized through the pitching cylinder. The invention optimizes the parameters of the articulation mechanism, enhances the rigidity of the steering mechanism, improves the stability of the vehicle, and reduces the load of the oil cylinder; through the horizontal and vertical adjustment, it satisfies the realization of a large turning angle when the front and rear vehicle bodies are wide.

Description

technical field [0001] The invention belongs to the field of articulated special vehicles, in particular to a hinge mechanism for articulated special vehicles. Background technique [0002] Due to the special articulated steering mechanism, the articulated special vehicle has the advantages of small turning radius, good maneuverability, wide adaptability and high productivity, and is widely used in agriculture, forestry, construction, emergency rescue, military and other fields. my country has a vast territory, complex and diverse terrain, and five types of terrains: plains, plateaus, mountains, hills, and basins. There are many swamps, rivers, and lakes and they are widely distributed. For these soft, slippery or rough roads, articulated special vehicles can be better adapted. Various complex environments; in addition, in the preemptive rescue of natural disasters such as floods, typhoons, blizzards, earthquakes, landslides, and mudslides, and in infrastructure construction ...

AI Technical Summary

Problems solved by technology

[0006] The invention provides an adjustable special vehicle hinge mechanism with auxiliary and enhanced equivalent stiffness of the steering mechanism. The swing and the wide front and rear car bodies lead to relatively small steering angles at the front and rear cars, and it is impossible to achieve large turning angles and small radii for articulated special vehicles.
