For the 4 wheel driven vehicle; The front and back bridge is drive axle, and at this moment, horizontal change-speed box is except front driving axle left half axle 9, right axle shaft 10 outputting powers; Also need give the rear driving axle outputting power; Promptly need three takeoff outputs, the general employing increases a power takeoff 8, with transmission of power (as shown in Figure 1) to rear driving axle; And the vertical change-speed box of putting is passed to (as shown in Figure 2) on the forward and backward drive axle through adopting part-time case 13 respectively with power.
It is thus clear that present preposition 4 wheel driven change-speed box is because of being provided with a power takeoff 8; And power takeoff 8 when installing because of the structural limitations of inner hypoid screw bevel gear; Cause power takeoff 8 and engine cylinder body space little, when change-speed box docked with driving engine, assembling is inconvenience very; In addition, during power takeoff 8 et out of orders, can't dismantle maintenance separately, need whole transmission assembly be disassembled; Have again, the preposition 4 wheel driven change-speed box of existing structure difficult arrangement in car load, the installing space that needs is bigger, assembling inconvenience.
Summary of the invention
The technical matters that the utility model will solve provides a kind of horizontal 4 wheel driven change-speed box, is that a kind of structure based on existing preposition 4 wheel driven change-speed box is improved; Being applied to forerunner is that master, rear-guard are on the 4 wheel driven vehicle of assisting, simple structure, compact conformation; Be easy to car load and arrange the 4 wheel driven speed changer structure, this structure can solve the car load Layout Problem effectively, assembling and after-sales service problem; The space that needs is little, and amount of parts is few.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of horizontal 4 wheel driven change-speed box comprises change-speed box main body and diff; Said change-speed box main body comprises the input shaft and the output shaft of horizontal parallel; Differential casing is driven by output shaft through engagement component;
Its special feature is: said horizontal 4 wheel driven change-speed box also comprises horizontally disposed rear output shaft, and rear output shaft and input shaft, output shaft are perpendicular; Be fixedly connected with driving bevel gear on the said differential casing, this driving bevel gear be located at the driven bevel pinion constant-mesh on the rear output shaft.
As the optimization of the utility model, said driving bevel gear and driven bevel pinion are the hypoid screw bevel gear.
As the qualification of the utility model, said engagement component is to be located at the gear on the output shaft and to establish the mesh component that is fixed on the differential casing.
As the further qualification of the utility model, said mesh component is gear ring or differential gear.
As the conventional characteristic of the horizontal 4 wheel driven change-speed box of said structure, said input shaft and output shaft are provided with many to the engaging tooth wheels.
The principle of work of the utility model is following: engagement component gains impetus and is passed to differential casing from output shaft; Power is passed to the propons left and right wheels via axle side gear; Being passed to rear output shaft by driving bevel gear and driven bevel pinion simultaneously reaches to rear-end gear reduction; In order to the driving rear axle left and right wheels, bridge power distribution before and after realizing.
Owing to adopted above-mentioned technical scheme; The utility model compared with prior art; The technological advance of being obtained is: the utility model is through increasing driving bevel gear and driven bevel pinion on differential casing; Torque part from output shaft is passed on the differential casing is passed through differential casing in-to-in planetary side gear with transmission of torque to left and right sides semiaxis, thereby gives vehicle front power; Simultaneously; The engagement of torque another part through driving bevel gear and driven bevel pinion that is passed on the differential casing is passed on the rear output shaft, through transmission shaft on the automobile, with transmission of power to rear driving axle; Thereby give automobile back wheel power, whole power transmission has realized 4 wheel driven vehicle needs.The utility model is integrated into the diff end with the moving bevel gear of principal and subordinate, realizes to the rear driving axle transmission that through increasing a power takeoff simple in structure, compact, taking up room reduces greatly, is easy to more arrange in the car load thereby cancelled in the prior art.
The utility model can be applicable in the four-wheel drive car driving system, and this change-speed box can be manual or automatic transmission with hydraulic torque converter, realizes horizontal 4 wheel driven.
The utility model below will combine Figure of description and specific embodiment to do further explain.
