Description
Technical field
The utility model relates to a kind of link arm, and in particular, it relates to a kind of bow-shaped arm.
Background technique
Along with the progress of industrial society, modern people instead of walking with instruments such as automobiles.In Hyundai Motor manufacturing, the component related to are a lot, and any component on automobile are all the keys of the quality determining a car.Bow-shaped arm is the common component of one on automobile, and for connecting the transmission of two axles, a kind of bow-shaped arm so exactly affects the transmission accuracy of two axles.
Existing bow-shaped arm generally comprises the arm body arcuately arranged, angle between the two end part of arm body is obtuse angle, the two ends of arm body are also provided with the attachment hole for being connected with axle, the both sides of arm body are all generally that plane is arranged, on arm body, stress-bearing capability is everywhere all similar, and actual when using, and the force bearing point of arm body is uneven, power suffered by the inner side of arm body is larger compared to other places, so often easily deform herein and rupture.Existing bow-shaped arm, because the deficiency in this design causes its structural strength inadequate, often causes it yieldingly even to rupture, causes serious impact to the quality of a car.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is the bow-shaped arm providing a kind of structural strength high.
For achieving the above object, the utility model provides following technological scheme: a kind of bow-shaped arm, comprise the arm body arcuately arranged, angle between the two end part of described arm body is obtuse angle, the two ends of described arm body are also provided with the attachment hole for being connected with axle, the inner side of described arm body is provided with the first stiffening rib, the outside of described arm body is provided with the second stiffening rib, described first stiffening rib and the second stiffening rib are surrounded by groove at wall body, and described first stiffening rib is provided with near the side of groove and thickens boss.
Preferably, the thickness of described first stiffening rib is greater than the thickness of described second stiffening rib.
Preferably, thickening boss described in is by thick thinning setting from the first stiffening rib side to the second stiffening rib side.
Preferably, a side opening of described attachment hole is that inner small and outside big taper is arranged.
Preferably, the side of described attachment hole is provided with side channel, and described side channel is communicated with described attachment hole.
Preferably, described side channel is two and Central Symmetry about described attachment hole is arranged.
The utility model has following advantage: the inner side of the arm body of the utility model bow-shaped arm is provided with the first stiffening rib, the outside of arm body is provided with the second stiffening rib, first stiffening rib and the second stiffening rib are surrounded by groove at wall body, and the first stiffening rib is provided with near the side of groove and thickens boss.The first stiffening rib wherein arranged makes the stress-bearing capability inside arm body strengthen, second stiffening rib makes the stress-bearing capability outside arm body strengthen, and, due to arm body inner side suffered by power larger compared to other places, thicken boss so to be provided with near the side of groove at the first stiffening rib, the stress-bearing capability of the inner side of arm body can be made like this to be greater than other any one stress-bearing capability.This design, when not wasting material, makes the stressed of this arm body can rational design more, makes its structural strength better.

Fig. 2 is the axonometric drawing two of the utility model bow-shaped arm embodiment one;
Fig. 3 is the side view of the utility model bow-shaped arm embodiment one;
Fig. 4 is the structural representation of the utility model bow-shaped arm embodiment two.
In figure: 1, arm body; 11, the first stiffening rib; 111, boss is thickened; 12, the second stiffening rib; 13, groove; 14, attachment hole; 141, side channel.
Embodiment
With reference to shown in accompanying drawing, the utility model bow-shaped arm is further illustrated.
Embodiment: a kind of bow-shaped arm, comprises the arm body 1 arcuately arranged, and the angle between the two end part of arm body 1 is obtuse angle, general value is between 100 degree to 150 degree, preferably 120 degree, the power suffered by arm body 1 can be made so more even, and structural strength is higher.The two ends of arm body 1 are also provided with the attachment hole 14 for being connected with axle, the inner side of arm body 1 is provided with the first stiffening rib 11, the outside of arm body 1 is provided with the second stiffening rib 12, first stiffening rib 11 and the second stiffening rib 12 are surrounded by groove 13 at wall body, and the first stiffening rib 11 is provided with near the side of groove 13 and thickens boss 111.The first stiffening rib 11 wherein arranged makes the stress-bearing capability inside arm body 1 strengthen, second stiffening rib 12 makes the stress-bearing capability outside arm body 1 strengthen, and, due to arm body 1 inner side suffered by power larger compared to other places, thicken boss 111 so to be provided with near the side of groove 13 at the first stiffening rib 11, the stress-bearing capability of the inner side of arm body 1 can be made like this to be greater than other any one stress-bearing capability.This design, when not wasting material, makes the stressed of this arm body 1 can rational design more, makes its structural strength better.
Secondly, the thickness of the first stiffening rib 11 is greater than the thickness of the second stiffening rib 12.This is that power suffered by the inner side of arm body 1 is larger compared to other places, so the thickness of the first stiffening rib 11 makes more greatly its stress-bearing capability stronger, the stress-bearing capability of the inner side of arm body 1 can be made so further to be greater than other any one stress-bearing capability.
Moreover thickening boss 111 is by thick thinning setting from the first stiffening rib 11 side to the second stiffening rib 12 side.The cast molding of this bow-shaped arm can be conducive to like this, and make to thicken the stressed more even of boss 111, and thicken when boss 111 is extended in groove 13 by the first stiffening rib 11 side and can link into an integrated entity with arm body 1, power is distributed on arm body 1, makes its stress-bearing capability stronger.
In addition, a side opening of attachment hole 14 is that inner small and outside big taper is arranged, and axle can be made like this to be more prone to insert connected time.
Embodiment two: the present embodiment and the difference of embodiment one are that the structure of attachment hole 14 is different, after axle is connected with attachment hole 14, due to the problems such as precision often easily and attachment hole 14 relatively rotate, cause transmission inaccuracy.So in the present embodiment, be provided with side channel 141 in the side of attachment hole 14, side channel 141 is communicated with attachment hole 14.So like this after axle inserts attachment hole 14, the projection that axle is arranged can be coordinated with side channel 141, make axle be subject to positioning action, can not relatively rotate with attachment hole 14.
Further, side channel 141 is two and Central Symmetry about attachment hole 14 is arranged, such symplex structure, and what can make between axle and side channel 141 is stressed more even, makes both connections more stable.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
