Description
Technical field
The utility model relates to the used power-shift transmission of a kind of power-shift transmission of engineering machinery, particularly loader, loader-digger, grader and bulldozer.
Background technique
Because the operating mode of engineering machinery is complicated and changeable, gearshift is frequent, for improving operating efficiency, does not need to cut off the power-shift transmission of power when generally adopting gearshift, and the shifting element of power-shift transmission is a Wet-type multi-disc formula friction clutch.The transmission system of China's engineering machinery adopts two turbine quaternary part fluid torque converters to add the form of planetary power-shift transmission mostly.This type of belt drive has simple in structure, the advantage of processing ease, but there is following some shortcomings part: the one, the gear number of speed changer is less, be generally two forward gears and one and retreat retaining, can not adapt to the operation of engineering machinery under the complex working condition condition, be difficult to guarantee that fluid torque converter works in efficient district; The 2nd, the transmission efficiency of two turbine quaternary part fluid torque converters is not high, and energy loss is bigger.Along with the development of technology, this type of belt drive more and more can not adapt to the needs of modern project machinery development.
Be the raising transmission efficiency, energy saving, external large-scale engineering machinery producer generally adopts the kind of drive of the power-shift transmission of the higher three element fluid torque converter of efficient and many gears.At present, each large-engineering machinery producer of China also begins to adopt the three element fluid torque converter to add the kind of drive of gear power-shift transmission gradually, but required many retainings power-shift transmission of China engineering machinery producer mainly relies on the product of companies such as buying ZF, Caterpillar, DANA.Therefore, developing the many retainings power-shift transmission with independent intellectual property right has great importance.
By the described a kind of clockwise and anticlockwise gearbox of ZL95196765.7, its feature is that axial dimension is little, good rigidly, and gear number is more.But it comes with some shortcomings: the one, and number of parts is more, and this speed changer has eight transmission shafts and 16 driving gears; The 2nd, the transmission chain length of some gear, transmission efficiency is on the low side, and its retaining drive path that advances is longer, has six outer gearings.
By the described power-shift transmission of ZL200320131395.6, be characterized in compact structure, part number is few, drive path is short, but it there are two deficiencys: the one, gear number is few, can only realize first three back three at most; The 2nd, axial dimension is big, on the axle of this kind speed changer two friction clutches and a plurality of gear is arranged, and on the maximum axles four gears is arranged, thereby makes the rigidity variation of speed changer.
Summary of the invention
The purpose of this utility model: overcome the deficiency that existing engineering machinery speed changer exists, provide that a kind of gear is many, good rigidly, volume is little, efficient is high, drive path is short, can adapt to the power-shift transmission of market demand.
A kind of power-shift transmission with nine gears, it is by an input shaft (I), an output shaft (VII), five jack shafts (II, III, IV, V, VI), six shift clutch (Q1, Q2, HT, L1, L2, L3) and a plurality of free gear (3,4,6,8,11,13) and fixed gear (2,5,7,9,10,12,14) form, except that output shaft, a shift clutch is all arranged on all the other the every axle, a free gear and a fixed gear is characterized in that: first fixed gear (2) while on the input shaft (I) often meshes with second free gear (4) and the maintenance of the 3rd free gear (6) on second jack shaft (III) on first jack shaft (II), and first free gear (3) on the input shaft (I) often meshes with second fixed gear (5) maintenance on first jack shaft (II); The 3rd fixed gear (7) on second jack shaft (III) often meshes with the 6th free gear (13) maintenance on the 5th jack shaft (VI); The 4th free gear (8) on the 3rd jack shaft (IV) often meshes with the 5th fixed gear (10) maintenance on the 4th jack shaft (V), and the 4th fixed gear (9) while and second fixed gear (5), the 5th free gear (11) and the 6th free gear (13) on the 3rd jack shaft (IV) keep engagement often; The 7th fixed gear (14) while on the output shaft often meshes with the 5th fixed gear (10) and the maintenance of the 6th fixed gear (12) on the 5th jack shaft (VI) on the 4th jack shaft (V); On the end on projection figure of speed changer, will there be each center of meshing relation to link to each other with line segment to gear, then constitute a pentagon and a quadrilateral; The first five root axle of speed changer (I, II, III, IV, V) with pentagonal array, (VI is VII) with quadrangular array for IV, V for back four axles of speed changer.
The topological structure of speed changer is a pentagon and a tetragonal combination, and pentagon and quadrilateral have a limit.
The 6th free gear (13) on the 5th jack shaft (VI) is served as the role of idle pulley in two transmissions that retreat retaining.
Can realize the velocity ratio expansion of wider range by on the part transmission shaft, adding one or more gears.
Transmission scheme of the present utility model adopts the fixed shaft type transmission, replaces the planetary transmission of traditional engineering machinery speed changer.In the vehicle of four-wheel drive, planet transmission needs transfer case, but the fixed shaft type speed changer does not need.In addition, the fixed shaft type speed changer has low cost of manufacture, and the power taking mouth is provided with advantages such as easy.For reducing the length of transmission shaft, improve rigidity, two gears at the most on any axle in the speed changer described in the utility model.For strengthening speed changer and matching capacity torque-converters, transmission design described in the utility model keeps off and retreats three retainings for advancing six.
