Heavy transport vehicle chassis with high trafficability

Abstract

The invention belongs to the technical field of vehicle engineering, and provides a heavy high-trafficability transport vehicle chassis which comprises steering axles, a driving axle and a steering synchronizing mechanism, the steering axles are installed at the front end and the rear end of the vehicle chassis, and the steering axles at the front end and the rear end of the vehicle chassis rotate synchronously; the drive axle is mounted on the vehicle chassis between the front and rear steering axles; the steering synchronizing mechanism is of a mechanical pull rod type structure connected between steering axles at the front end and the rear end of the vehicle chassis, and the mechanical pull rod type structure is connected to steering synchronizing swing arms of the steering axles at the front end and the rear end of the vehicle chassis. When the front steering axle steers, the steering synchronizing mechanism drives the steering axle at the rear end of the vehicle chassis to steer synchronously, synchronous steering of front and rear wheels of the heavy transport vehicle is achieved, the turning radius is small, the steering angle error is small, and the fault that front and rear steering angles are not synchronous is not prone to occurring; when running on mountainous regions, construction sites and other occasions, the vehicle can more easily pass through uneven severe road conditions and narrow road surfaces, and the passing performance is better.

Description

technical field [0001] The invention belongs to the technical field of vehicle engineering, and in particular relates to a chassis of a heavy-duty high-throughput transportation vehicle. Background technique [0002] As the demand for heavy-duty transport vehicles in the market continues to expand, heavy-duty transport vehicles, as a kind of heavy-duty vehicles, generally need to increase the structural strength of the heavy-duty vehicle chassis in order to increase its carrying capacity. [0003] At present, the chassis of heavy-duty transport vehicles is usually a riveted structure or a welded structure. In order to improve production efficiency and reduce transportation costs, heavy-duty transport vehicles have multiple steering axles and drive axles. The steering axle is arranged on the front side of the frame, and the drive axle is arranged on the rear side. . At the same time increase the length of the chassis. While this solution increases the load capacity, it also...

AI Technical Summary

Problems solved by technology

While increasing the load, this solution also brings some disadvantages, for example, the distance between the steering axle and the drive axle is too large, resulting in greater disturbance and stress on the frame

Due to the long overall length of the frame, the steering bridge is concentrated on the front side of the frame, which increases the turning radius of the vehicle. When passing through a narrow road with a small turning radius or making a U-turn at an intersection, the operation is difficult and the safety is low.
