Front axle damping device for driverless sweeping vehicle

Abstract

The invention relates to the technical field of driverless sweeping vehicles, in particular to a front axle damping device for a driverless sweeping vehicle. The device comprises a chassis and a frontaxle located below the chassis. The device is characterized in that driving hubs are arranged at the two ends of the front axle; and tires are assembled on the driving hubs; the middle section of thefront axle is provided with a horizontal hinge seat so as to be hinged to the chassis; and the hinge axis of the horizontal hinge seat is perpendicular to the length direction of the front axle. Thedevice further comprises at least two sets of elastic buffer assemblies which are used for connecting the chassis and the front axle and have the vertical elastic telescopic function; the buffer directions of the elastic buffer assemblies are vertically arranged; and the elastic buffer assemblies are arranged on the two sides of the horizontal hinge base respectively. The device has the advantagesof simple structure, high applicability, cost-saving performance and high cost performance. The problem of the advancing stability of the whole vehicle when the driverless sweeper encounters a ruggedroad surface in the working process can be solved, and the sensing accuracy of vehicle-mounted equipment is ensured.

Description

technical field [0001] The invention relates to the technical field of unmanned sweeping vehicles, in particular to a front axle damping device for unmanned sweeping vehicles. Background technique [0002] For unmanned sweeping vehicles, they will encounter rough roads during the work process. It is necessary to ensure the accuracy of equipment induction and the stability of the vehicle. This inevitably requires a special design for the vehicle suspension system. At present, the suspension system used in the vehicle chassis is mainly composed of the front axle suspension system and the rear axle suspension system. Both the front axle and the rear axle are designed as an integral suspension structure, that is, when one front wheel jumps, the other front wheel also jumps. It will jump accordingly and affect each other, and the overall suspension is easy to roll when the vehicle is turning, and the driving stability of the vehicle is also poor. How to develop a new type of fro...

At present, the suspension system used in the vehicle chassis is mainly composed of the front axle suspension system and the rear axle suspension system. Both the front axle and the rear axle are designed as an integral suspension structure, that is, when one front wheel jumps, the other front wheel also jumps. It will jump accordingly and affect each other, and the overall suspension is easy to roll when the vehicle is turning, and the driving stability of the vehicle is also poor

How to develop a new type of front axle shock absorbing equipment, so as to solve the problem of vehicle stability when unmanned sweeping vehicles encounter rough roads during work, and ultimately ensure the accuracy of on-board equipment induction, has become an important issue in this field in recent years. Technical problems that need to be solved urgently
