Abstract
The utility model discloses a duplex drive axle with ultra-short wheel track, which comprises a main speed reducer, a brake, a half shaft, a hub brake drum and an axle case, wherein the main speed reducer is connected with the axle case by a bolt; the brake is connected with the axle case by a bolt; the hub brake drum is connected with a rear wheel hub by a wheel bolt; and the rear wheel hub is connected with a bolt through the half shaft. The duplex drive axle is characterized in that the distance between the center of an air chamber of the main speed reducer and a rear axle is set to be 354mm, and the distance between the center of the air chamber of the main speed reducer and an intermediate axle is set to be 702mm. The duplex drive axle greatly reduces the wheel track of the common duplex drive axle, lowers the weight and the cost of a whole vehicle, can be applicable to being arranged in the vehicle with a trolley frame, enhances the flexibility of the arrangement of the whole vehicle, and maintains the speed and the carrying capacity of the whole vehicle to be unchanged.
Description
Technical field
The utility model relates to automotive field, specifically a kind of two drive axles of ultrashort wheelspan duplex that are applicable to heavy type traction automobile single-stage reduction axle.
Background technology
At present, the tractor truck of trolley frame is little because of its energy consumption, use flexibly, stop easily that advantage has more and more obtained liking of users, but the deceleration vehicle bridge of mating large-scale wheel tractor, not only heaviness but also complete vehicle weight increase, can bear fully in small-sized vehicle bridge under the prerequisite of work load-carrying of trolley frame tractor truck and stress, use large-scale drive axle but to reduce the car load alerting ability of automobile, the influenced energy consumption of car load speed increases.
Summary of the invention
At the deficiency that prior art exists, technical problem to be solved in the utility model is, a kind of ultrashort wheelspan double drive axle of adaptation trolley frame tractor truck simple in structure, with low cost is provided.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of ultrashort wheelspan double drive axle, and it comprises main reduction gear, drg, semiaxis, wheel hub brake wheel, axle housing; Main reduction gear is connected with axle housing by bolt, drg is connected with axle housing by bolt, wheel hub brake wheel brake wheel is connected with rear-wheel hub by wheel bolt, rear-wheel hub is by the semiaxis bolt together, it is characterized in that: described main reduction gear air chamber width between centers back axle is provided with 354mm, and jackshaft is provided with 702mm.
The advantage of the two drive axles of the ultrashort wheelspan duplex of the utility model is: the wheelspan that has shortened the common double drive axle greatly, complete vehicle weight and cost have been reduced, applicable to the layout of dolly unwheeling, strengthened the alerting ability of the car load layout of automobile, and car load speed remains unchanged with load-carrying capacity.Broken doube bridge wheelspan unicity, a kind of driving doube bridge of dolly unwheeling is provided, than its deadweight of traditional doube bridge with cost is low and transfer torque and bearing capacity are constant; Jackshaft input, output bead and back axle input bead all adopt end face tooth bead, have guaranteed stability of transmission; This utility model has increased a selection again for the user, can increase the alerting ability of main engine plants' type selectings according to self road conditions and the more suitable vehicle of operating mode selection.
Description of drawings
Fig. 1 is the structural representation of the two drive axles of the ultrashort wheelspan duplex of the utility model;
The specific embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in further details;
As shown in Figure 1, be the structural representation of the ultrashort wheelspan double drive axle of the utility model, a kind of ultrashort wheelspan double drive axle, it comprises main reduction gear 1, drg 2, semiaxis 3, wheel hub brake wheel 4, axle housing 5; Main reduction gear 1 is connected with axle housing 5 by bolt 6, drg 2 is connected with axle housing 5 by bolt 7, wheel hub brake wheel brake wheel 4 is connected with rear-wheel hub 9 by wheel bolt 8, rear-wheel hub 9 is by semiaxis 3 bolt togethers, described main reduction gear 1 air chamber width between centers back axle is provided with 354mm, and jackshaft is provided with 702mm.
Development: heavier-duty 168 * 168 * 16 (high * wide * thick) cross section is adopted in axle housing 5 cross sections, the thickness of steel spring bearing is reduced, interior tendon is strengthened to reach original loading strength, the strength analysis of upper thrust rod support and lower thrust rod support process CAE designs and goes out, than before common support, the approximately light 15Kg of one component parts for assembly of a machine bridge weight, intensity is bigger.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
