Description
Technical field
The utility model relates to a kind of Novel drive axle final drive casing body structure, belongs to auto manufacturing.
Background technique
Drive bevel gear in Medium or severe type car main reducing gear of drive axle adopts the supporting type of the formula of bridging mostly, and object makes it obtain higher support stiffness, ensures that gear can correct engagement have higher working life.As shown in Figure 1, the formula that bridges supporting is also called two ends formula supporting, and namely the axle journal of gear rear and front end all supports with bearing.Owing to reducing gearbox will be arranged the structure of installing drive bevel gear small end spring bearing, drive bevel gear can only be assembled from the opposite side of reducing gearbox, affect by it, current drive bevel gear is the main reducing gear of formula supporting structure of bridging, are all structures that final drive casing is connected with driving pinion bearing housing Split bolt, otherwise drive bevel gear cannot be assembled.The shortcoming of this structure is the risk that amount of parts is more, processing technology is complicated, mating face exists leakage of oil.For the main reducing gear of the formula supporting structure that bridges, if the bearing support structure integrated with bevel housing can be realized, do not affect again the assembling of drive bevel gear, be then conducive to simplifying the structure of retarder, reduce weight, cost-saving.
Summary of the invention
The purpose of this utility model is to provide a kind of Novel drive axle final drive casing body structure, its structure optimizing main gearbox assembly, the lightweight reducing technology difficulty, realize car load, both the structure of final drive casing and bearing support one had been achieved, the assembling of drive bevel gear can be carried out again smoothly, do not increase the quantity of component, effectively simplify the structure of reducer shell.
The technical solution of the utility model is achieved in that a kind of Novel drive axle final drive casing body structure, by reducing gearbox, differential mechanism right bearing seat, differential mechanism right bearing seat connecting bolt, differential mechanism left bearing lid, differential mechanism left bearing lid connecting bolt forms, it is characterized in that: reducing gearbox is integrated with driving pinion bearing housing, differential case bearing bracket is made up of differential mechanism left bearing lid and differential mechanism right bearing seat, the projection of semicircular arc is had on the left of reducing gearbox, the differential mechanism left bearing lid of semicircular arc is fixedly connected with the projection on the left of reducing gearbox by two differential mechanism left bearing lid connecting bolts, the differential mechanism left bearing lid of semicircular arc and the male cooperation of semicircular arc form differential mechanism left bearing, differential mechanism right bearing seat with differential mechanism right bearing is fixedly connected on the right side of reducing gearbox by differential mechanism right bearing seat connecting bolt.
Good effect of the present utility model is that it has that structure is simple, assembling and easy to process, easy realization, lightweight and high reliability.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model.
Fig. 2 is the structural drawing of traditional main reducing gear housing assy.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further: as shown in Figure 1, a kind of Novel drive axle final drive casing body structure, by reducing gearbox 1, differential mechanism right bearing seat 2, differential mechanism right bearing seat connecting bolt 3, differential mechanism left bearing lid 4, differential mechanism left bearing lid connecting bolt 5 forms, it is characterized in that: reducing gearbox 1 is integrated with driving pinion bearing housing, differential case bearing bracket is made up of differential mechanism left bearing lid 4 and differential mechanism right bearing seat 2, the protruding 1-1 of semicircular arc is had on the left of reducing gearbox 1, the differential mechanism left bearing lid 4 of semicircular arc is fixedly connected with the protruding 1-1 on the left of reducing gearbox 1 by two differential mechanism left bearing lid connecting bolts 5, the differential mechanism left bearing lid 4 of semicircular arc coordinates with the protruding 1-1 of semicircular arc and forms differential mechanism left bearing, differential mechanism right bearing seat 2 with differential mechanism right bearing 2-1 is fixedly connected on the right side of reducing gearbox 1 by differential mechanism right bearing seat connecting bolt 3.
Driving pinion bearing housing in conventional structure and reducing gearbox are directly cast as one by final drive casing 1, the structure and differential bearing lid of final drive casing 1 assembling drive bevel gear small end spring bearing are directly cast as one and form differential mechanism right bearing seat 2, be connected on reducing gearbox 1 by 2 differential mechanism right bearing seat connecting bolts 3.First drive bevel gear and driving tapered gear shaft being taken up when main gearbox assembly assembles is fitted on final drive casing 1, again differential mechanism right bearing seat 2 is assembled on final drive casing 1, so both achieve the structure that driving pinion bearing housing is integrated with reducing gearbox, do not affect again the assembling of drive bevel gear, by the connection of differential mechanism right bearing seat connecting bolt 3, ensure that the rigidity of support of housing.
As shown in Figure 1, 2, driving pinion bearing housing 6 in Fig. 2, traditional reducing gearbox 7, bearing support connecting bolt 8 are reduced to the reducing gearbox 1 in Fig. 2, processing technology simplifies, weight at least alleviates 10%, realize car load lightweight and in reducing fuel consumption rate target etc. contribution significantly, promise well.
