Abstract
The utility model provides a safe and reliable medium bus rear drive axle assembly with low noise, which comprises a main speed reducer, an inter-wheel differential, a rear axle casing assembly, a hub, a brake drum, a brake assembly and a half axle. The main speed reducer and the inter-wheel differential are respectively mounted in a main speed reducer casing and the rear axle casing assembly, the hub is mounted on the rear axle casing assembly via a hub inner bearing and a hub outer bearing, the main speed reducer, the inter-wheel differential, the half axle, the hub and the brake drum are sequentially connected, the brake assembly is mounted on the rear axle casing assembly, and the main speed reducer adopts a single reduction structure with meshed bevel gears. The rear drive axle assembly adopts the single reduction structure, leads the main speed reduction ratio ranging from 4.625 to 5.666 and has large applicable range to power of an engine. The rear drive axle assembly has low noise which is lower than or equal to 68 decibel, thereby completely meeting noise requirements of the present domestic high-end seven-meter medium buses.
Description
Technical field
The utility model relates to medium bus rear driving axle assembly, especially 7 meters medium bus rear driving axle assemblies.
Background technology
In the existing home bus market, the share of market of 7 meters medium buss is very big always, and the trend that rises is year by year arranged, but the major part of determining is the low side vehicle.High-end vehicle (Cowes spy) since nineteen ninety-three be under the monopolization of Japanese Toyota Rodrigo Costa for a long time.
Along with the raising of domestic car load factory and parts manufacturer technical merit and technological level, constantly dwindling with the gap of Japanese passenger vehicle on integral level on the performance, but present stage on the noise of back axle assembly and integrity problem all the time difficulty breakthrough is arranged, whole
Depot need select for use the import back axle assembly can satisfy the requirement of car load noise when manufacturing and designing high-end vehicle.
Summary of the invention
The purpose of this utility model provides a kind of safe and reliable, medium bus rear driving axle assembly that noise is low.
This medium bus rear driving axle assembly comprises main reduction gear, inter-wheel differential, rear axle housing assembly, wheel hub, brake wheel, brake assembly and semiaxis.Main reduction gear and inter-wheel differential are installed in respectively in final drive casing and the rear axle housing assembly; On rear axle housing assembly, main reduction gear, inter-wheel differential, semiaxis, wheel hub, brake wheel are connected wheel hub successively by the inside and outside bearing installation of wheel hub, and brake assembly is installed on the rear axle housing assembly; Main reduction gear adopts finishing bevel gear cuter ingear single-stage slowing-down structure.
The utility model rear driving axle assembly adopts the single-stage slowing-down structure, and base ratio contains 4.625～6.666, and the apply engine power range is big; Noise is low, and rear driving axle assembly noise≤68 decibels can satisfy the noise requirement of domestic existing high-end 7 meters medium buss fully.
As improvement, brake assembly is the brake assembly of hydraulic braking, and includes the brake clearance automatic mechanism, disposes existing brake clearance automatic mechanism and can satisfy in the national standard standard configuration requirement about coach luxury coach.
As improvement, main reduction gear with respect to the installation offset distance at axle housing center is: right avertence 30mm, following inclined to one side 28.58mm; The main reduction gear mounting flange is apart from axle housing centre distance 337.59mm.
Description of drawings
Fig. 1 is a rear driving axle assembly structure scheme drawing;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view (hydraulic brake structural representation) of Fig. 1
The specific embodiment
The assembly of rear driving axle shown in the figure is made up of main reduction gear 1, inter-wheel differential 16, rear axle housing assembly 2, wheel hub 6, brake wheel 10, brake assembly 11 and semiaxis 3.Main reduction gear and inter-wheel differential are installed in respectively in final drive casing and the rear axle housing assembly, and main reduction gear is connected successively with inter-wheel differential, semiaxis, wheel hub, brake wheel, and brake assembly is installed on the rear axle housing assembly.
Brake assembly 11 is the brake assembly of hydraulic braking, specification is ∮ 320mm (external diameter) * 110mm (width), compares with similar back axle assembly, and brake strap is widened, when guaranteeing that lock torque satisfies the car load use, increased the resistance to abrasion of brake strip.Simultaneously the brake assembly standard configuration is installed ABS anti-lock device and brake clearance automatic mechanism, and left and right sides drg all adopts independent oil pipe fuel feeding when work, further increases the safety and the reliability and stability of drg work.
Main reduction gear 1 adopts bevel-gear pair 14 ingear single-stage slowing-down structures, outer bearing 12 sizes of driving gear 17: ∮ 38.100mm (internal diameter) * ∮ 82.550mm (external diameter) * 29.370mm (thickness); Neck bearing 13 sizes of driving gear 17: ∮ 41.275mm (internal diameter) * ∮ 104.775mm (external diameter) * 36.513mm (thickness); Ring gear 18 theoretical external diameter ∮ 302mm.Differential bearing 15 sizes: ∮ 60.325mm (internal diameter) * ∮ 100mm (external diameter) * 25.4mm (thickness).Main reduction gear max. output torque: 9140N.m.
Main reduction gear with respect to the installation offset distance at axle housing center is: 30 (right avertence) * 28.58 (down partially); The main reduction gear mounting flange is apart from axle housing centre distance 337.59mm.
During use, power passes to semiaxis from the input of main gearbox mouth through main reduction gear and inter-wheel differential, and the flange by the semiaxis outer end is passed to wheel through wheel hub, brake wheel at last, and powered vehicle is travelled.Main reduction gear 1 noise is low, reliability is high.Rear driving axle assembly noise≤68 decibels.
