The automobile rear axle housing has a concise structure and high bearing capacity, is easy to produce and can well improve a production qualification rate.
Description
Technical field
The utility model relates to the vehicle bridge accessory, especially relates to a kind of vehicle rear-axle housing.
Background technology
Vehicle bridge (also claiming axletree) links to each other with vehicle frame (or self-supporting body) by suspension, and automotive wheel is installed at two ends, and its function is to transmit all directions application force between vehicle frame (or self-supporting body) and the wheel.Vehicle bridge can be all-in-one-piece, and two ends are by the suspension system supports vehicle body, so rigid axle cooperates with dependent suspension usually; Vehicle bridge also can be a breakaway-element, separately by the suspension system supports vehicle body, so broken bridge of car and independent suspension adapted.According to the difference of type of drive, vehicle bridge also is divided into steeraxle, drive axle, steering drive axle and support bridge, and wherein steeraxle and support bridge all belong to driven bridge.Most of automobiles adopt FE/RD, so propons is as steeraxle, and back axle is as drive axle; Preposition front drive automobile then propons becomes steering drive axle, and back axle serves as support bridge.The structure of steeraxle is basic identical, is made up of two steering swivels and a crossbeam.
Axle housing is the base part that main reduction gear, diff, semiaxis, wheel hub and suspension are installed, and main effect is supporting and protection main reduction gear, diff and semiaxis etc., and simultaneously, axle housing is again one of main component parts of running device.Driving axle housing should have enough strength and stiffness, and quality is little, and is convenient to the dismounting and the adjustment of main reduction gear.Driving axle housing can be divided into integral axle housing and separable housing two classes on structure.Integral axle housing is that axle housing separates manufacturing with final drive casing, the two bolt together together, its structural advantages is when the technology status of checking main reduction gear and diff or dismounting, need not remove whole drive axle from car, thereby keep in repair more conveniently, generally be used for all kinds of automobiles.Separable housing is axle housing and final drive casing cast solid, and generally is divided into two sections and is fused by bolt, and this axle housing is easy to casting, but must remove whole bridge when safeguarding main reduction gear and diff, otherwise can't open and inspect main reduction gear and diff.Axle housing specifically has following function: 1 and driven bridge bear car mass together, 2, the relative axial position of left and right driving wheel is fixed, 3, during running car, bear various counter-forces, application force and moment that drive wheel transmits, and pass to vehicle frame by suspension.
The utility model content
The purpose of this utility model provides a kind of simple in structure, vehicle rear-axle housing with strong load-carrying capacity.
The utility model is that the technical scheme that its technical matters of solution is adopted is,
Vehicle rear-axle housing, comprise axle housing, described axle housing is formed putting snapping by upper shell and lower house, upper shell and lower house are the evagination arc shape, and the axle housing middle part is provided with opening, and the central axis of this opening is vertical vertical with axle housing, also be provided with the axle housing lid in addition, the axle housing lid is sealed the opening at axle housing middle part, and axle housing lid and this opening are provided with flange hole, connects fastener and by flange hole the axle housing lid is connected on the axle housing.
Further, described axle housing two ends are respectively arranged with cast and connect the end, and described connection end is provided with tightens up the junction surface, and the cast connecting portion is gradually opens shape, tighten up at the place, junction surface to be straight tube-like.
In addition, be provided with oil hole, be provided with plug in this oil hole at described upper shell.
The beneficial effects of the utility model are, this vehicle rear-axle housing is formed by connecting by axle housing body up and down, and it is simple for structure, produces easily, has stronger load-carrying capacity simultaneously, can be good at improving the production qualification rate.
Description of drawings
Fig. 1 is the structural representation of the utility model vehicle rear-axle housing;
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.
As Fig. 1, shown in Figure 2, the vehicle rear-axle housing that the utility model proposes comprises axle housing 100, described axle housing is put snapping by upper shell 110 and 120 pairs of lower houses and is formed, upper shell 110 and lower house 120 are the evagination arc shape, axle housing 100 middle parts are provided with opening 103, the central axis of this opening 103 is vertical vertical with axle housing 100, also be provided with axle housing lid (not marking among the figure) in addition, the axle housing lid is sealed the opening 103 at axle housing 100 middle parts, axle housing lid and this opening 103 are provided with flange hole, connect fastener and by flange hole the axle housing lid are connected on the axle housing 100.Be provided with feeding axle housing in-to-in oil hole 111 at described upper shell 110, be provided with plug in this oil hole 111.
Be used to connect carriage and other parts, described axle housing two ends are respectively arranged with cast and connect end 101 and connecting portion 102, connection end 101 is provided with tightens up junction surface 1011, connection end 102 is provided with tightens up junction surface 1021, cast connecting portion 101 and connecting portion 102 are gradually opens shape, at the junction surface 1011 and 1021 places, junction surface tighten up and be straight tube-like.
This vehicle rear-axle housing is formed by connecting by axle housing body up and down, and it is simple for structure, produces easily, has stronger load-carrying capacity simultaneously, can be good at improving the production qualification rate.
More than show and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
