Special chassis for low-floor wide-field-of-view sanitation truck

Abstract

The invention discloses a special chassis for a low-floor wide-field-of-view sanitation truck. The special chassis comprises a cab, a frame, a front axle, a rear axle, a front suspension system and a rear suspension system; the frame is a closed truss structure formed by connecting a crossbeam and a longitudinal beam, the frame stretches across above the front suspension system and the rear suspension system, the lower ends of the front suspension system and the rear suspension system are respectively connected to the front axle and the rear axle, and the upper ends of the front suspension system and the rear suspension system are fixed to the chassis frame; the cab is fixed on the front part of the frame, the front end of the front axle is provided with a cab door, the cab door is made of a piece of landing high-strength transparent glass, a windshield of the cab adopts a large-area wide-field-of-view windshield similar to that of a bus, and a primary step of the cab stays on the same plane with a floor in the cab. By adopting the special chassis for the low-floor wide-field-of-view sanitation truck, the problems that people are inconvenient to get into and out of the cab due to the long distance from the sanitation truck to the ground and the traveling stability is poor and the field of view of the cab is not wide due to the high center of gravity of the vehicle can be solved.

Description

technical field [0001] The invention relates to a sanitation vehicle chassis, in particular to a special chassis for a low-floor wide-view sanitation vehicle. Background technique [0002] At present, the sanitation maintenance of urban roads has basically realized the mechanized operation mode, which is completed by sanitation vehicles such as road sweepers and sweepers. Existing road sanitation vehicles are generally refitted with a second-class chassis, that is, the chassis of a truck is used. The defects of this structural chassis are: first, the chassis is relatively high from the ground, and it takes several steps to reach the ground of the cab. The cab is inconvenient. At the same time, the high chassis also raises the center of gravity of the vehicle, resulting in poor driving stability. Second, the cab has a small visual range, a wide field of vision, and many visual blind spots, which are not conducive to observing the surrounding road conditions and operating effe...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a special chassis for a sanitation vehicle with a low floor and a wide field of view, which solves the problems in the prior art that the chassis of a sanitation vehicle is high from the ground, causing inconvenience in getting up and down the driver's cab, and the high center of gravity of the vehicle, resulting in poor driving stability and a poor view of the driver's cab.
