Abstract
The utility model provides a kind of light-duty gate-type rear axle of automobile multi-purpose, which includes hub reduction gear, rear axle housing, rear primary gearbox, rear axle casing support, rear axle casing, hub reduction gear connecting flange, hub reduction gear reinforced support；Wherein hub reduction gear, rear axle housing are connected by bolt, form " door " formula structure, by the door type structure, axle half shafts center is thus lifted to wheel center line or more, thus the road clearance bigger in axle half shafts center following implemented.The light-duty gate-type rear axle of this multipurpose is suitable for the repacking of offroad vehicle, has many advantages, such as that the raising road clearance is big, structure is simple, at low cost, applicable vehicle is wide.
Description
Technical field
The utility model relates to automobile axle more particularly to a kind of light-duty gate-type rear axles of automobile multi-purpose.
Background technique
Currently, automobile axle generally uses no hub reduction gear, axle housing section for the singl-reduction axle of circular cross section,
Since the main reducing gear size of singl-reduction axle is larger, cause the vehicle road clearance smaller, axle housing section is circular cross section,
In the case where axle housing outer diameter is constant, axle housing bending strength can only be enhanced by inwardly thickening axle housing, but thicken axle housing and be bound to
Cause whole bridge weight to increase, influences the driving performance of automobile.The automotive axle of above structure is unable to satisfy off-road enthusiast to vapour
The requirement of vehicle cross-country ability, it is therefore desirable to a kind of light-duty gate-type Biodge device of multipurpose, the bending strength and automobile of Lai Tigao vehicle bridge
Road clearance.
Utility model content
The utility model provides a kind of light-duty gate-type rear axle of automobile multi-purpose, which is suitable for changing for offroad vehicle
Dress has many advantages, such as that the raising road clearance is big, structure is simple, at low cost, applicable vehicle is wide.
The utility model achieves the above object through the following technical schemes:
A kind of light-duty gate-type rear axle of automobile multi-purpose, including hub reduction gear, rear axle housing, rear primary gearbox, it is special
Sign is: the hub reduction gear is provided with positioning convex platform；The rear axle housing both ends are provided with the hub reduction gear with location hole
Connecting flange；The hub reduction gear can be inserted into the location hole of the hub reduction gear connecting flange by positioning convex platform,
Hub reduction gear, rear axle housing are connected by bolt again, form " door " formula structure；The rear primary gearbox is installed on rear axle
The centre of shell, the torque that transmission shaft is passed over distribute to hub reduction gear.
Further, the rear axle housing, section configuration are rectangle.
Further, the hub reduction gear and the rear axle housing are reinforced connecting by hub reduction gear reinforced support, mention
The strength and stiffness of high " door " formula structure.
Further, the hub reduction gear connecting flange and rear axle housing connecting pin are rectangular cross section, with hub reduction gear
Connecting pin is the flange face with location hole.
Further, be provided with rear axle casing support, rear axle casing inside the rear axle housing, rear axle casing one end with
Rear axle casing support links together, and the other end is connected on hub reduction gear connecting flange.
The utility model has the following beneficial effects:
Gate-type bridge structure can increase the road clearance, enhance the passability of automobile；Rectangular cross section axle housing, it is limited in space
In the case of improve the bending strength of axle housing entirety；According to the needs of the market, it can be derived in the case where not changing mold
The gate-type axle assembly of wheel rim deceleration device, three kinds of products of single axle assembly and hub reduction gear without hub reduction gear meet
The demand of different clients.
Detailed description of the invention
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Fig. 1 is a kind of structural schematic diagram of the light-duty gate-type rear axle of automobile multi-purpose described in the utility model；
Fig. 2 is the enlarged drawing of a-quadrant in Fig. 1.
Label declaration:
1. hub reduction gear, 2. rear axle housings, 3. rear primary gearbox, 4. rear axle casing supports, 5. rear axle casings, 6. wheel sides
Retarder connecting flange, 7. hub reduction gear reinforced supports, 21. location holes, 22. positioning convex platforms, 23. bolts.
Specific embodiment
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments:
As shown in Figure 1 and Figure 2, the light-duty gate-type rear axle of a kind of automobile multi-purpose is provided with wheel side at 2 both ends of rear axle housing
Retarder connecting flange 6, hub reduction gear connecting flange 6 and 2 connecting pin of rear axle housing are rectangular cross section；Connect with hub reduction gear 1
Connecing end is the flange face with location hole 21；Rear axle housing 2 is transitioned into circle from square cross-section by hub reduction gear connecting flange 6
Section, so as to the connection of hub reduction gear 1 and rear axle housing 2.Positioning convex platform 22, hub reduction gear 1 are provided on hub reduction gear 1
It is inserted into the location hole 21 of hub reduction gear connecting flange 6 by positioning convex platform 22, then passes through bolt 23 for hub reduction gear
1, rear axle housing 2 is connected, and forms " door " formula structure.7 lower end of hub reduction gear reinforced support is connect with hub reduction gear 1, on
End is connect with the bracket on rear axle housing 2, further strengthens the intensity and rigidity of " door " formula structure.
Since above-mentioned " door " formula structural union is to be bolted, can derive in the case where not changing mold
The gate-type axle assembly of pulley side reducer, three kinds of products of single axle assembly and hub reduction gear without hub reduction gear are full
The demand of sufficient different clients.
Rear axle housing 2 is rectangular cross section, and the bending strength of axle housing entirety is improved in the limited situation in space, but in vapour
When vehicle tilts, the lubricating oil in rear primary gearbox 3 is possible to gather left end or the right end of rear axle housing 2, causes main reducing gear
Driving and driven gear oil starvation work.Occur such case in order to prevent, be provided with inside rear axle housing 2 rear axle casing support 4, after
Bridge casing 5,5 one end of rear axle casing link together with rear axle casing support 4, and the other end is connected on wheel side connecting flange 6, lead to
Later bridge casing support 4, rear axle casing 5 can prevent lubricating oil from largely gathering the left and right both ends of rear axle housing 2, main after guarantee
Effectively lubricating is obtained inside retarder 3.
More than, only specific embodiment of the present utility model, but protection scope of the utility model is not limited thereto,
Anyone skilled in the art within the technical scope disclosed by the utility model, the variation that can readily occur in or replaces
It changes, should be covered within the scope of the utility model.
