The utility model is because back axle comprises the bridge bag, bridge tube left half axle and right axle shaft, one end of left half axle and right axle shaft is connected on the deceleration transmission parts, the other end of left half axle and right axle shaft is respectively by bearing fixing two at back axle, bridge bag and bridge tube are welded to connect, brake system is fixed by bolts on the bridge tube, promptly be that back axle is the one back axle, so load-carrying capacity is strong, attachment security is reliable, the bearing force of back axle can not be added on the deceleration box when car bears a heavy burden, thereby the phenomenon of deceleration box fracture is taken place, and deceleration box and back axle is easy to connect reliable, easy to maintenance, the utility model has solved the shortcoming of other form differential speed motor.
In a word, the utility model compact conformation rationally, solved the stressed phenomenon of rupture of deceleration box; Solve the speed reduction gear box assembly problem, saved the tank material cost.
Description of drawings
Fig. 1 dissects structural representation for the integral type differential speed motor assembly on the utility model battery-driven car.
The specific embodiment
Below in conjunction with accompanying drawing the integral type differential speed motor assembly on the utility model battery-driven car is described in further detail.
As shown in Figure 1, integral type differential speed motor assembly on the utility model battery-driven car, comprise the motor part, deceleration box, the deceleration transmission parts, back axle and the brake system that is arranged on the back axle both sides, the deceleration transmission parts are installed in the deceleration box, deceleration box is captiveed joint with back axle, deceleration box comprises left box body and right case, connect with bolt between left box body and the right case, back axle comprises back axle bag 31, bridge tube 32, left half axle 20 and right axle shaft 30, one end of left half axle 20 and right axle shaft 30 is connected on the deceleration transmission parts, the other end of left half axle 20 and right axle shaft 30 is respectively by bearing fixing two at back axle, back axle bag 31 and bridge tube 32 are welded to connect, and brake system is fixed by bolts on the bridge tube.The deceleration transmission parts comprise first order speed reduction gearing and second stage speed reduction gearing, first order speed reduction gearing partly is connected with motor, second stage speed reduction gearing is connected with diff, diff comprises 2 differential bearings 21,2 gamp teeth 22, differential casing and diff bearing pins 24,2 gamp teeth are installed in the differential casing, the two ends of differential casing are fixed on the deceleration box by differential bearing 21, and left half axle 20 and right axle shaft 30 insert respectively in the cooresponding gamp tooth 22.First order speed reduction gearing comprises one-level gear wheel shaft 13, one-level driven gear 16, gear on the one-level gear wheel shaft 13 and 16 engagements of one-level driven gear, second stage speed reduction gearing comprises secondary gear axle 18, secondary driven gear 26, gear on the secondary gear axle 26 and 18 engagements of secondary driven gear.
