The utility model gathers a lot of advanced technologies and passes the strict road test of military, which is a new production with stable performance and credible quality.
Description
Technical field
The utility model relate to a kind of two generation the military vehicle back axle, belong to automotive technology class technical field.
Background technology
The drive axle of general automobile is by axle housing, main reduction gear, diff, semiaxis, compositions such as wheel hub and brake assembly.At first pass to main reduction gear from change-speed box or part-time case through the torque of universal driving device input drive axle, after this increases torque and corresponding rev down, distribute to left and right sides two-semiaxle through diff, pass to the wheel hub of drive wheels at last by the flange of semiaxis outer end.Driving axle housing is made up of final drive casing and axle tube.Wheel hub by bearings on axle tube.This axle casing rigidity is not enough, and the semiaxis dismounting is inconvenient, and the safety system of not braking.
The utility model content
The purpose of this utility model provide a kind of two generation the military vehicle back axle, it the is integrated advanced automotive technology of a lot of world todays has improved the performance of original vehicle.
The purpose of this utility model is achieved in that
Two generation the military vehicle back axle, comprise axle case assy, main gearbox assembly, semiaxis and rear brake panel ASSY, described axle case assy internal fixation is equipped with main reduction gear, this main reduction gear respectively with about two semiaxis be connected, this semiaxis holds assembly with the rear-wheel hub tape spool and is connected, this semiaxis holds assembly with the rear-wheel hub tape spool and is connected with the sedan-chair shell by bearing, and this rear brake assembly is captiveed joint with wheel hub.
Described brake assembly comprises back brake caliper assembly and rear brake panel ASSY, and this rear brake panel ASSY is captiveed joint with wheel hub, and this back brake caliper assembly is captiveed joint with axle housing.
Described main reduction gear comprises single reduction gear and diff, is equipped with differential locking-device in this diff.
Be equipped with the ABS antiblock device on this brake assembly.
Described axle case assy is the integral solder axle case assy.
The utlity model has following advantage:
The brake system safety and stability; The axle housing good rigidly is convenient to assembling, adjustment and the maintenance of retarder; The semiaxis dismounting is with easy to maintenance; High safety, good reliability.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Fig. 1 is the utility model scheme drawing
The specific embodiment
Sedan-chair behind the two generation military vehicles, comprise axle case assy, main gearbox assembly, semiaxis and rear brake panel ASSY, described axle case assy internal fixation is equipped with main reduction gear, this main reduction gear respectively with about two semiaxis be connected, this semiaxis holds assembly with the rear-wheel hub tape spool and is connected, this semiaxis holds assembly with the rear-wheel hub tape spool and is connected with axle housing by bearing, and this rear brake assembly is captiveed joint with wheel hub; Described brake assembly comprises back brake caliper assembly and rear brake panel ASSY, and this rear brake panel ASSY is captiveed joint with wheel hub, and this back brake caliper assembly is captiveed joint with axle housing; Described main reduction gear comprises single reduction gear and diff, is equipped with differential locking-device in this diff; Be equipped with the ABS antiblock device on this brake assembly; Described axle case assy is the integral solder axle case assy.
At first pass to main reduction gear from change-speed box or part-time case through the torque of universal driving device input drive axle, after this increases torque and corresponding rev down, distribute to left and right sides two-semiaxle through diff, the rear-wheel hub tape spool that passes to drive wheels by semiaxis holds assembly at last, realizes the motion of automobile.
The main gearbox assembly structure is the single reduction final drive of assembling differential locking-device, and differential locking-device is assemblied in the diff as shown in fig. 1.The function of diff be automobile turning exercise or other enforcement situations under, can rely on wherein planetary wheel with corresponding rotating speed rotation, thereby the both sides drive wheels be rolled on the ground and fricton-tight with different rotating speeds.The function of differential locking-device is that differential locking-device makes diff not play differential action when the single wheel of automobile is on the less road surface of adhesive ability, and the moment of torsion that transmits from main reduction gear all is assigned on the opposite side drive wheel, makes automobile be able to cruising.There has been this covering device can strengthen the driveability of automobile greatly by bad road.
Rear axle housing assembly adopts integral solder axle housing form, and its advantage is to have bigger strength and stiffness, and is convenient to assembling, adjustment and the maintenance of main reduction gear.
Semiaxis holds transferring power between the assembly at diff and rear-wheel hub tape spool, semiaxis and rear-wheel hub tape spool hold assembly Jie bearings on rear axle housing assembly as shown in Figure 1, this kind structure semiaxis only bears torque, and any counter-force and moment of flexure are not all born in two ends, this kind structure promptly is called fully floating axle and supports, and its advantage is to be easy to dismounting, only need back out the screw on the semiaxis flange, semiaxis can be extracted out from axle tube, and wheel and axle housing can support automobile in the same old way.
Two generations military vehicle back axle employing plate disc brake, its principle are by the gap between hydraulic pressure work control back brake caliper assembly and the rear brake panel ASSY, make both contact frictions realize braking.Disc type brake usefulness is stable, and immersion back usefulness reduces few, need only can recover normally through twice braking, and the maintenance repair work is easy.
Two generation the military vehicle back axle also be equipped with the ABS antiblock device, the ABS wheel speed sensors is installed in the rear-wheel hub tape spool by detection and holds gear ring on the assembly, the wheel movement feedback of status is arrived computerized control system, computer system meeting automatically regulating brake-pressure, carry out the anti-lock adjusting to being tending towards locked wheel, wheel can locking when reaching emergency braking, makes between wheel and ground to keep friction of rolling, realizes optimum braking effect.
