Abstract
The utility model discloses an automobile for transporting cargoes, and in particular relates to a novel semi-trailer tractor. The novel semi-trailer tractor mainly comprises an engine, a passing-through drive axle and a front rotary disk which are mounted on a chassis of a tractor, and a cargo-carried vehicle body and a rear rotary disk which are mounted on the chassis of a semi-trailer, wherein the cargo-carried vehicle body is connected with the chassis of the tractor and the chassis of the semi-trailer respectively through the front rotary disk and the rear rotary disk; a front hinging rack is arranged at the rear part of the chassis of the tractor; a drive axle and a rear hinging rack are arranged on the chassis of the semi-trailer; the front hinging rack on the chassis of the tractor is connected with the rear hinging rack on the chassis of the semi-trailer through a hinging shaft; and the passing-through drive axle on the chassis of the tractor is connected with the drive axle on the chassis of the semi-trailer through a universal drive shaft. The novel semi-trailer tractor has the advantages of small drift diameter and good passing-through performance, and has strong adaptability to off-road surfaces such as deserts, swamps, farmlands, mines and the like.
Description
Technical field
The utility model relates to the automobile that a kind of transporting cargo is used, specifically a kind of novel artic.
Background technology
The artic that the transporting cargo that travels on road is at present used generally is comprised of tractor truck and common superimposed trailer, and the vehicle bridge of common superimposed trailer is relatively-stationary the connection with the loading car body at horizontal surface, and namely vehicle bridge can not be rotated relative to the loading car body.When turning, the front-wheel orbital radius of the wheel driving trace radius ratio tractor truck of superimposed trailer is little a lot.So the latus rectum when present artic is turned is larger, and is poor by performance, is not suitable in the turning than the narrow road face.During automobile turning, the difference of the maximum turn radius of outboard wheels and the minimum turning radius of inboard wheel is latus rectum when turning.During turning, latus rectum also can be described as the needed minimum surface width of road of Ackermann steer angle.The vehicle bridge of present common superimposed trailer is not drive axle, and wheel is follower, there is no propulsive effort, and superimposed trailer can only move under the power that pulls of tractor truck.When these Vehicle Driving Cycles during on the road surface uneven, soft, muddy, that obstacle is arranged; often can pile up a lot of obstacles before the wheel of superimposed trailer, produce very large resistance, all tractive forces can only lean on the wheel of tractor truck; the tyre skidding that usually causes tractor truck affects the operation of vehicle.Therefore, present artic is relatively poor to the conformability of the non-highway pavement transportation such as desert, marsh, farmland, mine.
Summary of the invention
It is less that task of the present utility model is to provide a kind of latus rectum, good by performance, to the strong novel artic of conformability of the non-highway pavements such as desert, marsh, farmland, mine.
For realizing above-mentioned task, technical solution of the present utility model is:
a kind of novel artic, mainly by the driving engine of installing on the tractor truck chassis, run through drive axle, front rotating disk, the loading car body of installing on chassis of semi-trailer, rear rotating disk consists of, the loading car body by front rotating disk be connected rotating disk and be connected with chassis of semi-trailer with the tractor truck chassis respectively, rear portion, described tractor truck chassis arranges front body cradle, drive axle and rear body cradle are set on chassis of semi-trailer, front body cradle on the tractor truck chassis is connected with rear body cradle on chassis of semi-trailer by jointed shaft, the drive axle that runs through on the tractor truck chassis is connected with drive axle on chassis of semi-trailer by universal drive shaft.
Described universal drive shaft can stretch in the longitudinal direction.
Described front body cradle and rear body cradle can stretch in the longitudinal direction.
Described front body cradle and rear body cradle in the longitudinal direction or two simultaneous retractables, perhaps one of them is flexible.
The utlity model has latus rectum less, good by performance, to the strong advantage of conformability of the non-highway pavements such as desert, marsh, farmland, mine.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
as shown in Figure 1, a kind of novel artic, mainly by the driving engine 11 of installing on the tractor truck chassis, run through drive axle 3, front rotating disk 2, the loading car body 4 of installing on chassis of semi-trailer 9, rear rotating disk 10 consists of, loading car body 4 by front rotating disk 2 be connected rotating disk 10 and be connected with chassis of semi-trailer with tractor truck chassis 1 respectively and be connected, the front body cradle 5 that can stretch is in the longitudinal direction installed at the rear portion on tractor truck chassis 1, drive axle 12 and rear body cradle 8 are installed on chassis of semi-trailer 9, the One On The Chassis front body cradle 5 of tractor truck is connected with rear body cradle 8 on chassis of semi-trailer 9 by jointed shaft 6, on the tractor truck chassis, 1 the drive axle 3 that runs through is connected with drive axle 12 on chassis of semi-trailer 9 by the universal drive shaft 7 that can stretch in the longitudinal direction.
During use, the engine power of installing on the tractor truck chassis with the drive axle of transmission of power to chassis of semi-trailer, makes the wheel of chassis of semi-trailer also have propulsive effort by running through the universal drive shaft between drive axle, tractor truck and superimposed trailer.The rear body cradle of installing on the front body cradle that install at rear portion, tractor truck chassis and chassis of semi-trailer can stretch in the longitudinal direction (can be two simultaneous retractables, can be also that one of them is flexible).When tractor truck was turned, chassis of semi-trailer can turn certain angle in the opposite direction around rear center of turntable like this, thus make the wheel driving trace of chassis of semi-trailer can be very near the wheel trajectories on tractor truck chassis.So just reduce the latus rectum when turning, improved the performance of passing through of artic; Simultaneously, also improved the lateral stability of artic.
Claims (4)
1. novel artic, comprise the driving engine of installing on the tractor truck chassis, run through drive axle, front rotating disk, the loading car body of installing on chassis of semi-trailer, rear rotating disk, the loading car body by front rotating disk be connected rotating disk and be connected with chassis of semi-trailer with the tractor truck chassis respectively, it is characterized in that: rear portion, tractor truck chassis arranges front body cradle, drive axle and rear body cradle are set on chassis of semi-trailer, front body cradle on the tractor truck chassis is connected with rear body cradle on chassis of semi-trailer by jointed shaft, the drive axle that runs through on the tractor truck chassis is connected with drive axle on chassis of semi-trailer by universal drive shaft.
