Abstract
A double-axle structure of rear wheels for small and medium sized truck relates to a transmission structure of small sized trucks. The structure comprises a rear axle, and is characterized in that the rear axle is connected with a tandem axle at front end; the main transmission shaft is connected with the transmission shaft of the tandem axle; and the rear end of the transmission shaft of the tandem axle is connected with the speed reducing assembly of the rear axle. The structure has the following advantages: the rear wheels of a small and medium sized truck are provided with double axles, and the rear wheels are increased to four, so that slippage phenomena on road surface with poor road conditions are reduced; and meanwhile, the loading capacity can be improved if the vehicle body and the power of the engine are slightly changed.
Description
Technical field:
The utility model relates to small-sized bogie drive mechanism.
Background technology:
Middle-size and small-size bogie is meant the bogie of load carrying ability below 10 tons, is generally the four-wheel structure, and main transmission box is connected with the deceleration assembly of back axle by transmission shaft, realizes power transmission.
Heavy motor vehicle more than 10 tons is generally the structure of back axle four wheel drive, or the above driving of doube bridge, main driving axle connects then with the perforation bridging earlier and just is connected with the rear axle speed-reducing assembly of rearmost end, connect bridge construction and fix a perforation axle housing on the bridge deceleration assembly body skin for connecting, be equipped with in this axle housing and connect transmission shaft, speed reduction gearing, then the side speed reducer structure is connected with the deceleration assembly gear of vehicle bridge, connect bridge transmission shaft two and be fixed with drive coupling, be connected with main driving axle, rear end back axle with realization, give back axle power transmission.
Middle-size and small-size bogie is generally the four-wheel structure, in intermountain path or the bad road surface walking of road conditions, skidding often takes place in trailing wheel, thereby we propose the back axle four wheel drive and just can overcome this problem, simultaneously middle-size and small-size bogie add connect bridge construction to vehicle frame, driving engine as long as after changing a little, a perforation bridge can improve 3 tons of load carrying abilities, and the increase of load carrying ability has in other words also reduced skidding.
The perforation bridge construction of bogie can not directly be used on the middle-size and small-size car more than 10 tons, because connecting the reducer input shaft spacing of transmission shaft axle center line and this bridge deceleration assembly is more than the 200mm, dish angle tooth module is greater than 10mm, thereby perforation axle housing space is big, can not directly apply to middle-size and small-size car.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defective, and a kind of middle-size and small-size bogie back wheel double-bridge structure is provided.
Scheme of the present utility model is: comprise back axle, it is characterized in that the perforation bridging of back axle and front end connects, main driving axle is connected with perforation bridge transmission shaft, connects bridge transmission shaft rear end and is connected with the rear axle speed-reducing assembly.
Advantage of the present utility model is: middle-size and small-size bogie trailing wheel is provided with two drive axles, makes the trailing wheel number be increased to 4 wheels, reduces skidding on the road surface of road conditions difference, makes slightly under the change at car body, engine power etc. simultaneously and just can improve load carrying ability.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 connects the bridge construction scheme drawing for the utility model.
Fig. 3 is the A-A rotation amplification view of Fig. 2.
The specific embodiment:
Structure of the present utility model is: comprise back axle (3), it is characterized in that back axle (3) is connected with the perforation bridge (2) of front end, main driving axle (1) is connected with perforation bridge transmission shaft (4), connects bridge transmission shaft (4) rear end and is connected with back axle (3) deceleration assembly.
Because bogie perforation bridge (2) gabarit is big more than 10 tons, can not directly overlap and be used in below 10 tons on the bogie, because bogie vehicle frame below 10 tons, driving engine are little, slow down simultaneously assembly inner disc angle tooth, planetary modulus is little, connects bridge (2) deceleration assembly and the axle housing Outside Dimensions provides condition for dwindling.
Dish angle tooth, planetary wheel modulus that bogie below 10 tons connects in the bridge (2) are provided with the corresponding modulus that connects bridge (2) less than bogie more than 10 tons, thereby to make the reducer input shaft (5) that connects bridge (2) deceleration assembly be 120～180mm with connecting bridge transmission shaft (4) axial line spacing.And these data are dwindled, and deceleration assembly shell, perforation axle housing Outside Dimensions are dwindled, and just are suitable for the installation with bogie back wheel double-bridge structure below 10 tons.
Claims (2)
1, middle-size and small-size bogie back wheel double-bridge structure, comprise back axle (3), it is characterized in that back axle (3) is connected with the perforation bridge (2) of front end, main driving axle (1) is connected with perforation bridge transmission shaft (4), connects bridge transmission shaft (4) rear end and is connected with back axle (3) deceleration assembly.
2, middle-size and small-size bogie back wheel double-bridge structure according to claim 1, it is characterized in that connecting the reducer input shaft (5) of bridge (2) deceleration assembly and connecting bridge transmission shaft (4) axial line spacing is 120～180mm.
