Quasi-rhombus city public streetcar

Abstract

The invention discloses a rhombus urban public trolleybus, comprising a chassis, an antenna, an electric motor and a trolleybus body positioned on the chassis, wherein, the electric motor and the antenna used for being connected with a power supply device are arranged on the trolleybus body, the chassis comprises a frame and a front wheel, a rear wheel, a left middle wheel and a right middle wheelarranged in rhombus shape on a frame, the front wheel and the rear wheel are connected with a steering mechanism, the left middle wheel and the right middle wheel are connected with a driving mechanism, the front end of the trolleybus body takes the shape of a shuttle, a steering wheel of the steering mechanism is arranged at the middle part of the front end of the trolleybus body. The inventionis a rhombus urban public trolleybus which has small wind resistance, low energy consumption, small turning radius, flexible operation, good trafficability characteristic, good collision safety and light weight.

Description

technical field [0001] The invention mainly relates to the field of vehicle engineering, in particular to a diamond-shaped city public tram. Background technique [0002] The wheels of urban buses generally adopt the traditional rectangular chassis arrangement, that is, the general two-axle four-wheel structure. In order to increase the load capacity of some urban buses, two two-axle four-wheel carriages are articulated. The common feature of this type of city bus is that the carriage is supported by the front and rear axles, and each axle is symmetrically arranged with a set of tires along the longitudinal center plane of the vehicle, a total of four sets of tires. City buses generally adopt a chassis structure in which the rear axle is driven and the front wheels are steered. Urban buses generally have fixed lines and operating rules, which are convenient for laying special cables near the bus lines, and use electric drives instead of internal combustion engine drives, wh...

AI Technical Summary

Problems solved by technology

When designing the front end of a traditional four-wheeled rectangular vehicle, due to the layout of the front wheels and the requirements of the driver, the front end of the body cannot be made into a shuttle-like shape, and the drag coefficient cannot be optimally reduced

Secondly, the body layout of existing urban public trams is low, resulting in smaller approach angles, departure angles, and longitudinal passing angles, and poor passability. If the body layout is high, the center of mass of the entire vehicle will be raised, resulting in poor handling stability , especially for urban public trams with large volume and heavy weight
