Abstract
The invention belongs to system of vehicle transmission technical fields, and in particular to a kind of breakaway-element axle housing for independent suspension.The present invention on axle housing by increasing perforation pin-and-hole structure, axle housing is linked together with suspension by a pin shaft, since pin shaft inside axle housing completely by passing through, it is completely encapsulated in inside axle housing, without individually maintaining pin shaft, avoid exposure to it is outer caused by collide with failure, and cause pin shaft to get rusty due to will not paddling etc. vehicle, lead to rotate not flexible or pin shaft clamping stagnation so as to avoid because getting rusty.The side muscle of axle housing can increase the torsion stiffness of vehicle.The present invention cooperates the integrated design of frame suspension, can effectively reduce weight, reduces axle housing processing and assembles the influence to using.
Description
Technical field
The invention belongs to system of vehicle transmission technical fields, and in particular to a kind of breakaway-element axle housing for independent suspension.
Background technique
Current divided axle majority is connected using two kinds of structures with suspension system:
The first structure is that external frame structure is connected with suspension system, which is to increase by one at left and right sides of axle housing
A bracket or frame structure, axle housing is not direct to be connected with suspension system, but is connected by bolt or pin shaft with frame, and frame is logical
Bolt is crossed to be connected with suspension.
Second of structure is that the axle housing of divided axle is connected using shaft-cup with pin shaft, although suspension system is directly and pin
Axis is connected, but after assembling needs that pin shaft is connected with axle housing by bolt, is interference fit between pin shaft and axle housing.
The weight of vehicle is increased, and to guarantee frame due to increasing a frame for the first connection type
In the intensity of complex road condition when driving, frame needs high intensity, will cause the increased costs of vehicle, simultaneously because frame
Structure is limited by the size of divided axle, is affected to the arrangement of suspension.
For second of connection type, since axle housing needs to clamp pin shaft and axle housing using shaft-cup, needed for this structure
Axle housing and shaft-cup machining accuracy it is higher, slightly deviation will lead to two pin shaft of front and back concentricity it is insufficient, so as to cause bridge
Shell discontinuity and be broken.
Summary of the invention
(1) technical problems to be solved
The present invention proposes a kind of breakaway-element axle housing for independent suspension, is added with solving how to reduce weight, reducing axle housing
The technical issues of work and assembly difficulty.
(2) technical solution
In order to solve the above-mentioned technical problem, the present invention proposes a kind of breakaway-element axle housing for independent suspension, the axle housing
Lower part is opened up there are two pin hole is penetrated through, for across pin shaft；Two side plates on axle housing top are directly connected with suspension；The top of axle housing
Portion has the reinforcing rib of two perforation axle housings or so, is connected respectively with left and right sides suspension connecting plate.
Further, axle housing uses monoblock cast structure.
Further, the rear and front end of pin hole protrudes from the two sides of axle housing.
Further, 100mm length distance part progress machine adds inside the rear and front end of pin hole, and machine adds rear both ends to have limit
Boss.
(3) beneficial effect
Breakaway-element axle housing proposed by the present invention for independent suspension will by increasing perforation pin-and-hole structure on axle housing
Axle housing is linked together with suspension by a pin shaft, since pin shaft inside axle housing completely by passing through, is completely encapsulated in axle housing
Portion, without individually maintaining pin shaft, avoid exposure to it is outer caused by the originals such as collide with failure, and will not be paddled due to vehicle
Pin shaft gets rusty because caused by, leads to rotate not flexible or pin shaft clamping stagnation so as to avoid because getting rusty.The side muscle of axle housing can
Increase the torsion stiffness of vehicle.The present invention cooperates the integrated design of frame suspension, can effectively reduce weight, reduces axle housing and adds
The influence of work and assembly to using.
Detailed description of the invention
Fig. 1 is breakaway-element of embodiment of the present invention axle housing schematic diagram.
Specific embodiment
To keep the purpose of the present invention, content and advantage clearer, with reference to the accompanying drawings and examples, to tool of the invention
Body embodiment is described in further detail.
The present embodiment proposes a kind of breakaway-element axle housing for independent suspension, and structure is as shown in Figure 1.The axle housing is using whole
Body cast structure opens up two perforation pin holes 1 in axle housing lower part, for protecting pin shaft not across pin shaft, and using axle housing
The problems such as corrosion can be generated.Two side plates 2 on axle housing top are directly connected with suspension by bolt, are conducive to frame suspension one
Change design.The top two sides of axle housing have the reinforcing ribs 3 of two perforation axle housings or so, respectively with left and right sides suspension connecting plate phase
It even, can be auxiliary under the premise of guaranteeing vehicle driving stationarity when vehicle frame is by unilateral side distortion in vehicle by longitudinal force
It helps vehicle frame antitorque, increases the intensity of axle housing, while guaranteeing vehicle frame-suspension rectangular configuration.Being passed through for assembling in the present embodiment
The pin hole of logical pin shaft does not need integrated machine and adds, and the machine of can reduce adds difficulty, it is only necessary to 100mm length inside the pin hole of rear and front end
Apart from part, carry out machine adds, and machine adds rear both ends to have positive stop lug boss.The axle housing adds pin hole to make bridge by protruding from the machine of axle housing two sides
Shell entirety stress.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
Claims (4)
1. a kind of breakaway-element axle housing for independent suspension, which is characterized in that the lower part of the axle housing open up there are two perforation pin
Hole, for across pin shaft；Two side plates on the axle housing top are directly connected with suspension；The top of the axle housing has two and passes through
Lead to the reinforcing rib of described axle housing or so, is connected respectively with left and right sides suspension connecting plate.
2. axle housing as described in claim 1, which is characterized in that the axle housing uses monoblock cast structure.
3. axle housing as described in claim 1, which is characterized in that the rear and front end of the pin hole protrudes from the two of the axle housing
Side.
4. axle housing as described in claim 1, which is characterized in that inside the rear and front end of the pin hole 100mm length distance portion
Carry out machine is divided to add, machine adds rear both ends to have positive stop lug boss.
