Abstract

The invention belongs to four-wheel trolley chassis devices, and particularly relates to a four-wheel trolley chassis structure with a suspension. The four-wheel trolley chassis structure comprises a rear wheel driving assembly, a base and a front wheel suspension. The rear wheel driving assembly is fixed to the base through two rear wheel supporting frames and two driving motor bases. A right rear wheel train and a right rear wheel train driving motor are connected through a coupler. A left rear wheel train and a left rear wheel train driving motor are rotationally connected through a synchronous belt. A front suspension upper support is fixedly connected to the base and located on the central axis of the base. A front suspension lower support is fixedly connected to an elastic front beam and located in the center of the elastic front beam. The front suspension upper support and the front suspension lower support are rotationally connected through a front suspension shaft. By means of drive of rear wheels, servo drive of universal wheels on the front portion and independent control of the rear wheel left and right driving motors, the front wheel suspension system ensures that ground grip and movement are stable, the overall structure is simple, movement is flexible, and implementing is easy; and meanwhile the four-wheel trolley chassis structure is low in cost, capable of being used in various environments and wide in application range.

Description

technical field [0001] The invention belongs to a chassis device of a four-wheel trolley, in particular to a chassis structure of a four-wheel trolley with a suspension. Background technique [0002] Compared with the three-wheel chassis, the four-wheel chassis has better turning stability. Compared with more wheel chassis, the resistance of the wheel system is small, the structure is simple, easy to implement, and the comprehensive cost performance is high. It is widely used in various vehicles, wheel-type robots, etc. In transportation equipment, it has a good application prospect. [0003] At present, the small chassis structure is basically divided into six-wheel system, four-wheel system, and three-wheel system. The chassis structure of the six-wheel system is complicated, and the balance ability of the three-wheel system structure is poor. The existing four-wheel system has no suspension device, and the passing capacity is not strong. Contents of the invention [0...
