Abstract
There is provided a kind of secondary box of gearbox housing, have at the bottom of shell wall, shell, be integrated at the bottom of shell wall and shell, be shaped with three gear holes and a cylinder-bore at the bottom of shell, shell wall is shaped with multiple longitudinal vent rib, and shell wall is shaped with multiple reinforcement projection near link place.The utility model is one-body molded, improves rigidity and the intensity of secondary box of gearbox housing, carries heat sinking function, has that structure is simple, reliable, the characteristic of long service life.
Description
Technical field
The utility model belongs to automobile speed variator technical field, is specifically related to a kind of secondary box of gearbox housing, the integral housing structure especially matched with the transmission output shaft assembly of two jack shaft synchronize fully device structure.
Background technique
Automobile speed variator is the basic part installing each parts of speed changer, it is by the input shaft assembly in speed changer, output shaft assembly, the component such as gearshift assembly, an entirety is assembled into by certain mutual alignment relation, and support output shaft by certain velocity ratio relation Driving Torque, it plays installation to each parts, the effect of protection gear drive and accommodation lubrication wet goods MM part, visible, if casing rigidity is not enough, easily there is localized cracks, support place is worn and torn, the series of problems such as tapped hole damage, increase casing rigidity simply then can increase transmission assembly quality and cost of production, therefore proper strength is designed, the case of transmission of reasonable reduction cost of production is most important.Under prior art, case of transmission is made up of three parts mostly, comprise the anterior conical shell structure mated with clutch, the middle main tank shell construction protecting gearing actuator and the odd-side structure of mating with main tank, wherein, described odd-side structure is split type, odd-side is bolted by synchronizer protective housing and support cap housing and forms, the drawback that this split-type structural exists is that cost of production is too high, assembling maintenance trouble, casting technique is complicated, shell construction intensity, rigidity are inadequate, the raising of restriction vehicle performance; In addition, the case of transmission under prior art only uses as support unit guard block, and then by being connected speed changer cooling with cooling water tank, radiating effect is not ideal enough, is therefore necessary to improve.
Model utility content
The technical problem that the utility model solves: provide a kind of secondary box of gearbox housing, solves existing Split type speed-changing device odd-side shell construction complicated, and assembling, maintenance inconvenience, housing local strength, rigidity affect the technical problem of working life and poor heat radiation not.
The technical solution adopted in the utility model: secondary box of gearbox housing, have at the bottom of shell wall, shell, be integrated at the bottom of shell wall and shell, at the bottom of shell, be shaped with three gear holes and a cylinder-bore, shell wall is shaped with multiple longitudinal vent rib, and shell wall is shaped with multiple reinforcement projection near link place.
Wherein, the gear hole left and right intermediate shaft hole that comprises central principal axis bearing bore and linearly arrange with main bearing hole.
Cylinder-bore and air cylinder of speed changer match and are integrated into secondary box of gearbox housing, and profile and air cylinder of speed changer match.
Preferably, strengthen projection and comprise two semicircle jack shaft housings reinforcement projections and two square reinforcement projections.
Square reinforcement projection one and jack shaft housing are strengthened projection and are integrated into, and another and air cylinder of speed changer housing are integrated into.
The utility model advantage compared with prior art:
1, the utility model and twin countershaft transmission match, meet medium-heavy automobile to the rigidity of housing and strength demand, advantage that is short for twin countershaft transmission axial dimension, that be beneficial to arrangement is performed to ultimate attainment, for alleviating car load deadweight, improve bearing capacity, reduce noise, and the raising of transmission performance provides guarantee;
2, protected by auxiliary transmission the housing of synchronizer and bonnet housing to be integrated into, structure is simple, reduces mould cost of production, turn improves housing rigidity simultaneously, have excellent manufacturability, convenient for assembly with maintenance;
3, housing exterior walls is shaped with vent rib, and vent rib amasss auxiliary heat dissipation by increasing surface of shell, makes case of transmission be provided with heat sinking function again in original supporting and protective action basis;
4, be shaped with many places near housing joint and strengthen projection, projection is arranged guarantees the intensity of integrated shell, extends housing working life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model vent rib and reinforcement projection cube structure schematic diagram;
Fig. 3 is the utility model housing interior structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing 1-3, a kind of embodiment of the present utility model is described.
The utility model matches with two jack shaft synchronize fully speed changer, two jack shaft synchronize fully speed changer major-minor case respectively has two cover countershaft assemblys, it is advantageous that and the power of input can be passed to respectively two, both sides countershaft assembly, export after two-part power being merged by output shaft assembly again, in theory, the relatively single intermediate shaft structure of the moment of torsion that during work, every root intermediate bearing is subject to decreases 1/2nd, design accordingly, secondary box of gearbox housing of the present utility model, there is the shell wall 1 that is integrated into at the bottom of shell 2, comparatively set up gearbox cover structure and there is noise reduction, the advantage of gaining in strength, the utility model shell construction and twin countershaft transmission match, meet medium-heavy automobile to the rigidity of housing and strength demand, by short for twin countershaft transmission axial dimension, the advantage being beneficial to arrangement performs to ultimate attainment, for alleviating car load deadweight, improve bearing capacity, reduce noise, and the raising of transmission performance provides guarantee, at the bottom of shell, 2 are shaped with three gear holes 7 and a cylinder-bore 8, the left and right intermediate shaft hole 7-2 that described gear hole 7 comprises central principal axis bearing bore 7-1 and linearly arranges with main bearing hole, described cylinder-bore 8 matches with air cylinder of speed changer and is integrated into secondary box of gearbox housing, and profile and air cylinder of speed changer match, shell wall 1 is shaped with multiple longitudinal vent rib 3, and vent rib 3 amasss auxiliary heat dissipation by increasing surface of shell, makes case of transmission be provided with heat sinking function again in original supporting and protective action basis, shell wall 1 is shaped with multiple reinforcement projection near link 9 place, described reinforcement projection comprises two semicircle jack shaft housings and strengthens projection 4 and two square reinforcement projections 5,6, described square reinforcement projection 5 one and jack shaft housing are strengthened projection 4 and are integrated into, and strengthen projection 6 and are integrated into air cylinder of speed changer housing.Generally speaking; housing and the bonnet housing of auxiliary transmission protection synchronizer of the present utility model are integrated into; structure is simple; reduce mould cost of production, turn improve housing rigidity simultaneously, there is excellent manufacturability and heat dispersion; convenient for assembly with maintenance; be shaped with many places near housing joint and strengthen projection, guarantee the intensity of integrated shell, extend housing working life.
Above-described embodiment, just preferred embodiment of the present utility model, is not used for limiting the utility model practical range, therefore all equivalence changes done with content described in the utility model claim, all should be included within the utility model right.
