Abstract
An automobile with variable wheel tracks comprises a frame, an engine, a transmission shaft and wheels. A differential is arranged on the transmission shaft, the engine is connected with the differential through a gearbox, the transmission shaft comprises two half shafts, and an end of each half shaft is connected with one wheel through a universal joint. The automobile is characterized in that each half shaft comprises a fixed thick shaft and a telescopic thin shaft, one end of the thin shaft is connected with one wheel through the universal joint, the other end of the thin shaft is positioned in the thick shaft, the other end of the thick shaft is connected with the differential, an oil pump and hydraulic rods are arranged on the frame, an oil cavity of each hydraulic rod is communicated with the oil pump, a telescopic end of each hydraulic rod is connected with one wheel, a variable-pitch connecting rod is arranged between the frame and each wheel along the axial direction of the transmission shaft, and relative rolling devices are arranged among the variable-pitch connecting rods, the hydraulic rods and the wheels. When the automobile runs on a narrow road, the wheel tracks can be narrowed, so that running safety is ensured. When the road is wide, the wheel tracks can be widened, so that running stability of the automobile is improved.
Description
Technical field
The utility model relates to automobile technical field.
Background technology
Distance between the present car chassis two-wheeled all is changeless, runs into very narrow road, is difficult for passing through.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of the utility model is to provide a kind of variable wheel distances automobile, and it can and go according to different road conditions and require the adjustment wheelspan, and it is also very convenient on narrow road, to go.
In order to address the above problem; The utility model adopts following technical scheme: this variable wheel distances automobile; Comprise vehicle frame, driving engine, transmission shaft, wheel, transmission shaft is provided with diff, and driving engine is connected with diff through change speed gear box; Transmission shaft comprises two semiaxis, and the end of each semiaxis is connected with wheel through universal-joint; Described semiaxis comprises one section fixing thick axle, one section telescopic thin axle; One end of said thin axle is connected with wheel through said universal-joint, and the other end is positioned at thick axle, and the other end of said thick axle connects diff; Oil pump, hydraulic stem are set on the vehicle frame, and the oil pocket of hydraulic stem is communicated with oil pump, and the god of hydraulic stem contracts to hold and is connected with wheel; Axially be provided with the displacement connecting rod along said transmission shaft between said vehicle frame and the wheel; Be provided with relative tourelle between said displacement connecting rod, hydraulic stem and the wheel.
The beneficial effect of the utility model is: it is adjustable narrow wheelspan when road is narrow, guarantees driving safety; After having a lot of social connections in the road, can adjust wheelspan and broaden, to improve the stability of vehicle '.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation:
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is the birds-eye view of the utility model embodiment;
Among the figure: 1 universal-joint, 2 transmission shafts, 21 thick axles, 22 thin axles, 3 vehicle frames, 4 driving engines, 5 difies, 6 change speed gear boxs, 7 oil pumps, 9 displacement connecting rods, 10 wheels, 15 hydraulic stems, 16 relative tourelles.
The specific embodiment
Like Fig. 1, shown in Figure 2; This variable wheel distances automobile comprises vehicle frame 3, driving engine 4, transmission shaft 2, wheel 10, and transmission shaft 2 is provided with diff 5, and driving engine 4 is connected with diff 5 through change speed gear box 6; Transmission shaft 2 comprises two semiaxis, and the end of each semiaxis is connected with wheel through universal-joint; Described semiaxis comprises 21, one sections telescopic thin axles 22 of one section fixing thick axle; One end of said thin axle 22 is connected with wheel 10 through said universal-joint 1, and the other end is positioned at thick axle 21, and the other end of said thick axle 21 connects diff 5; Oil pump 7, hydraulic stem 15 are set on the vehicle frame 3, and the oil pocket of hydraulic stem 15 is communicated with oil pump 7, and the god of hydraulic stem 15 contracts to hold and is connected with wheel 10; Axially be provided with displacement connecting rod 9 along said transmission shaft 2 between said vehicle frame 3 and the wheel 10; Be provided with relative tourelle 16 between said displacement connecting rod 9, hydraulic stem 15 and the wheel 10.This relative tourelle can be bearing-type.
During use, wheel 10 wheelspans are broadened, slow down like need; Drive oil pump 7, oil pump 7 send oil for hydraulic stem 15, and hydraulic stem 15 promotes wheel and slowly moves outward; The thin axle 22 of transmission shaft stretches out from thick axle 21, and displacement connecting rod 9 trails simultaneously, finally realizes the change of wheel 10 wheelspans; Because the effect of hydraulic stem, vehicle wheel also promptly defines the position to wheel apart from not changing automatically.It is suitable to after-acceleration to change to, fast running.The process of dwindling the vehicle wheel distance is just in time opposite with it, is not giving unnecessary details.
