The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail:
Organization plan provided by the utility model is applicable to the front and back drive axle of trac., is the structural representation of front drive axle housing as shown in Figure 1 and Figure 2, Fig. 3, Figure 4 shows that the structural representation of rear driving axle.
Take front drive axle housing as example, specifically describe the technical solution of the utility model.
As shown in Figure 1 and Figure 2, front drive axle of tractor includes front driving axle housing assy 1, speed reducer assembly differential assembly 10 and brake assembly 4, and described speed reducer assembly is set to double reduction gear, is comprised of main gearbox assembly 2 and wheel reduction gear assembly 3.Described main gearbox assembly 2 is connected the two ends that are arranged at respectively driving axle housing assembly 1 and connect by semiaxis 5 with the wheel reduction gear assembly.
The characteristics such as described main gearbox assembly 2 adopts spira-bevel gearing mechanisms, and it is large to have an input torque, and driving efficiency is high, and stable working is reliable.Described wheel reduction gear assembly 3 adopts the planet speed reduction driving mechanism with three satellite gears, the mass motion good rigidly, and output speed is steady.Described semiaxis 5 adopts the full floating setting, has effectively overcome the impact of drive axle casing deformation on semiaxis.The main frame dynamic torque imports into from input flange, after main reduction gear deceleration 2, by semiaxis 5 power is passed to respectively both sides wheel reduction gear assembly 3, again by the hub reduction transmission, power is finally passed to planetary wheel carrier, thereby the tire on the drive wheels rolling is advanced.Its operating path is: main frame dynamic torque-input flange-main reduction gear-semiaxis-wheel reduction gear-tire.Be arranged at the axle side gear pad 11 on the axle side gear 12 in the described differential assembly 10, be set to the sleeping oil-groove pad of all steel, substitute the traditional copper pad, need not annually safeguard and change, rationally fixing, fully lubricated, reduced the wearing and tearing between axle side gear 12 and the axle side gear pad 11, prolong one times service life.
The utility model also includes gear ring support assembly 6, and described gear ring support assembly 6 is connected by tapered sleeve 7 and wheel reduction gear assembly 3, makes system's right alignment better, and strength of gear is even, and power output steadily prolongs 1/3rd service life.
Be provided with dust boot 9 on the oil sealing 8 of described wheel reduction gear assembly 3, prevent that effectively particulate matter to the infringement of oil sealing, improving the service life of oil seal greatly.
Planet wheel spindle adopts centreless grinding processing, and processing is simple, and steady quality doubles than step wheel shaft efficiency.
Fig. 3 and Fig. 1 are similar, are the difference of driving axle housing position, front and back, and dependency structure and use no longer separately elaborate here.
As shown in Figure 4, the utility model has also designed V-type registration device 13, and described V-type registration device is arranged on the mount pad of rear driving axle housing assy 15, and the V-block on the described V-type registration device 13 and the V-type groove on the tractor frame beam mate mutually.When drive axle is installed V-block is cooperated with V-type groove on the tractor frame beam, and the use bolted, this connection mode makes connection more firm, and fitting work efficient is higher, low cost of manufacture.Described V-type registration device 13 cooperates suspension gear (14) to use, and when trac. was worked, drive axle and vehicle frame were stressed evenly before and after making, and reduce the suffered shearing force of bolt.
