Zero-deviation trackless train

Abstract

The invention belongs to the technical field of trackless trains, particularly relates to a zero-deviation trackless train, and solves the problems of a conventional trackless train that wheel deviation is large, starting and braking are unstable, a turning radius is large, road surface requirements are high, the train is unsuitable to be too long, the load is unsuitable to be too much, only one-way driving is performed, and the trackless train cannot be backed. The zero-deviation trackless train comprises moving and dragging combinations, wherein each of the moving and dragging combinations comprises a driving gun carrier and a plurality of ordinary gun carriers which are sequentially hinged; each hinging seat for hinging comprises a one-freedom-degree hinging seat and a three-freedom-degree hinging seat of which the length dimensions and the width dimensions are consistent; the driving gun carriers and the ordinary gun carriers are two-wheel carriers, the length dimensions and the width dimensions of the driving gun carriers and the ordinary gun carriers are consistent, the mass center of each of the driving gun carriers is in the center of a carrier frame of the corresponding driving gun carrier, and the mass center of each of the ordinary gun carriers is in the center of a carrier frame of the corresponding ordinary gun carrier; a wheel shaft and tires are mounted in the middle part of two sides of each of the carrier frames; and the distance between the center of each wheel shaft and the center of a corresponding front hinging seat is equal to that between the center of the wheel shaft and the center of a corresponding rear hinging seat. According to the zero-deviation trackless train disclosed by the invention, wheel marks are consistent, the wheel deviation is zero, the turning radius is low, the transporting capacity is large, the length of the trackless train is increased, and the starting and the braking are smooth.

Description

technical field [0001] The invention belongs to the technical field of trackless trains, and in particular relates to a zero-deviation trackless train. The zero-deviation trackless train has the same wheel track and close to zero wheel deviation; the turning radius is small, the transportation capacity is large, the length is relatively long, and the braking is started. smooth. Background technique [0002] Trackless trains are usually used for luggage transportation in airports and railway stations. The existing trackless trains are generally composed of several four-wheeled flatbed trucks connected in series, which are pulled by traction drive vehicles. The four-wheeled flatbed truck is composed of a frame, a fixed axle, a steering axle and a traction frame. [0003] The existing trackless trains have the following problems: [0004] 1. Wheel deviation [0005] Let the wheelbase be b, the wheelbase be 2d, and the turning angle be a, then: the wheel deviation is c, [0...

AI Technical Summary

Problems solved by technology

[0016] In order to solve the problems of the existing trackless trains, such as large wheel deviation, unstable start and brake, large turning radius, high requirements on the road surface, the train should not be too long, the load should not be too large, and the one-way driving cannot reverse, etc., the present invention provides A zero-deviation trackless train
