Abstract
The invention discloses a novel through type double-stage wheel edge speed-reducing drive axle for heavy duty vehicles. The novel through type double-stage wheel edge speed-reducing drive axle for heavy duty vehicles comprises a main speed reducer, a differential mechanism, a wheel transmission device, a wheel edge speed reducer and an axle housing. The main speed reducer comprises a light integrated type main speed reducer shell (1), a first-stage speed-reducing driving cylindrical gear (2), a first-stage speed-reducing driven cylindrical gear (3), a second-stage speed-reducing driving bevel gear (4), a second-stage speed-reducing driven bevel gear (5) and an inter-axle differential mechanism are arranged inside the main speed reducer shell (1), and the inter-axle differential mechanism comprises an inter-axle differential mechanism shell (6) and four built-in planetary gears (7). The differential mechanism is of a sealing type differential mechanism structure, and comprises a differential mechanism shell (8), and a planetary gear (11), a half axle gear (9) and a split type universal joint pin (12) are located inside the differential mechanism shell (8). The novel through type double-stage wheel edge speed-reducing drive axle for heavy duty vehicles is small in size, the total height of the output end and the input end of a through shaft is small, the varieties of parts are few, the weight is light, and parts in the main speed reducer have good oil lubrication performance.
Description
Technical field
The present invention relates to the automobile-used through two-stage wheel-side reduction drive axle of a kind of novel heavy duty, belong to automobile drive axle field.
Background technology
The heavy motor vehicles used such as mine, water conservancy and other heavy constructions, because its load and road conditions change are large, usage condition is very complicated, so select the fuel efficiency that a kind of crossing ability is good, dynamic property has by force and again the higher speed of a motor vehicle and be satisfied with, be very difficult.For solving this contradiction, improve the comformability of automobile to various usage conditions, the structural shapes that adopt single-stage or double reduction final drive additional wheel side reducer when design driven bridge more.Traditional through two-stage wheel-side reduction drive axle is more because of through shaft place parts, makes its volume greatly and height gauge modest ability, is unfavorable for each transmission parts oil lubrication.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of novel heavy duty automobile-used through two-stage wheel-side reduction drive axle, it is characterized by that volume is little, through shaft mouth and input end bottom-to-top-height is low, parts kind is few, quality is light, advantages such as oil lubrication performance is good between each parts in main reduction gear.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A through two-stage wheel-side reduction drive axle for new construction heavy goods vehicles, comprises main reduction gear, diff, wheel drive, wheel reduction gear and axle housing, differs widely with first pre-structure, and the drive axle of new construction invention mainly contains following design improvement.
1, main reduction gear structure: optimal design lightweight integral type final drive casing 1, novelly subtract supporting type, allocation method and the support stiffness that shell can not only guarantee transmission gear in main reduction gear, also case weight is compared and has been reduced by 10 ㎏ left and right.This housing is contained within the drive bevel gear 4 of the active cylindrical wheel 2 of primary speed-down, driven cylindrical gear 3 and double reduction, driven wheel of differential 5 wherein, compact conformation, and making main reduction gear is 508 apart from drive axle distance between center line, than original design, has reduced by 50 ㎜; Subtract shell internal oil channel simplicity of design reasonable, guaranteed the circulation of lubricating oil smoothly.Interaxle differential has been removed the too complicated setting of interaxle differential according to planetary wheel auto-centering principle, adopt a kind of Novel integral inter-axle differential shell 6, four planetary wheel 7 integral body are wrapped in a housing, simple in structure, reduced amount of parts.
2, designs of differentials is sealed differential structure, and planetary wheel 11, axle side gear 9, split type center cross 12 are wrapped in differential gear box 8 bodies.For strengthening driven wheel of differential support stiffness, this Novel differential gear supporting driven wheel of differential side tapered roller bearing is selected the scheme that is greater than opposite side bearing, it is the diff left and right side bearing structure that differs in size, in when design, make to support the supporting-point of tapered roller bearing of driven wheel of differential side and the distance between load is greater than opposite side, compare with original design, strengthened the support stiffness of driven wheel of differential.It is 32020 that model is selected in left side, and right side bearing is 32017.
3, axle housing partly adopts the wall thickness variable section axle housing such as or not axle housing that equal strength method of designing develops and central siphon integral type, axle housing cross section is 145 * 168 * 16, and cross section is little, lightweight, load-carrying capacity is stronger, compares traditional syllogic axle housing list and props up axle housing and can realize and fall heavy 20kg.
What 4, wheel reduction gear adopted is thin and tall tooth system, gear ring 13 numbers of teeth 85, sun wheel 15 numbers of teeth 35, satellite gear 14 numbers of teeth 24.
When design wheel reduction gear sun and planet gear, the number of teeth relation of circumference of gear distribution gear must meet the condition of " (z1+z2) equaling integer divided by N ", (in formula, Z1 is: the sun wheel number of teeth, Z2 is the gear ring number of teeth, the number that N is satellite gear) otherwise designed sun and planet gear cannot assemble.This Novel wheel-side retarder meets sun and planet gear design condition.
Accompanying drawing explanation
