Abstract
The utility model discloses a combination of a motorcycle frame and a support lug, which comprises a support lug (1) and a frame pipe (2), wherein the support lug (1) has a flat plate structure; the frame pipe (2) is a circular pipe; the support lug (1) is provided with a convex rib (3) which is coaxially arranged with an axial line of the frame pipe (2); an upper inclined surface (3a) and a lower inclined surface (3b) are formed on the outer surface of the convex rib (3); the frame pipe (2) is attached to plate surfaces of the lower inclined surface (3b) of the convex rib and the support lug (1); an obtuse angle is formed between the circumferential surface of the frame pipe (2) and the upper inclined surface (3a) of the convex rib; the circumferential surface of the frame pipe (2) and the upper inclined surface (3a) of the convex rib are welded at the obtuse angle part; and the frame pipe (2) and the support lug (1) are fixed together. By arranging the convex rib on the support lug, the utility model not only enhances the strength of the support lug, but also facilitates the welding and processing of the support lug and the frame pipe, so that the support lug and the frame pipe are reliably connected, and the deformation, the slacking or the falling of the support lug can be avoided.
Description
Technical field
The utility model relates to a kind of motor bike member, particularly vehicle frame pipe on the motor bike and journal stirrup combination.
Background technology
Frame of motorcycle is welded to form by some pipes and connecting panel, and the fixing journal stirrup of the privileged site of pipe on vehicle frame is so that install parts such as driving engine, cover panel, pressure regulator by journal stirrup.At present, the fixed form of journal stirrup and vehicle frame pipe as shown in Figure 6, journal stirrup 1 is a slab construction, vehicle frame pipe 2 contacts with the plate upper thread of journal stirrup 1, upper and lower at contact position forms two little angles, and weld each angle, and journal stirrup 1 and vehicle frame pipe 2 are fixed together.Because the welding angle less (being no more than 60 °) between journal stirrup 1 and the vehicle frame pipe 2, the welding dead angle appears easily, the slag inclusion phenomenon easily takes place in welding, make the welding quality variation, cause the Joint strenght between journal stirrup 1 and the vehicle frame pipe 2 to reduce, the fixing that both fix is relatively poor, and journal stirrup becomes flexible easily and comes off, thereby influences the in-use performance of journal stirrup upper mounting component.In addition, journal stirrup is dull and stereotyped, and self rigidity is not enough, deforms easily and loses shape, and also can influence the in-use performance of associated components.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of connect firm frame of motorcycle pipe and journal stirrup combination.
The technical solution of the utility model is as follows: a kind of frame of motorcycle pipe and journal stirrup combination, comprise journal stirrup and vehicle frame pipe, wherein journal stirrup is a slab construction, the vehicle frame pipe is a pipe, its key is: described journal stirrup is provided with a convex tendon, the axis of the length direction of this convex tendon and vehicle frame pipe in the same way, and the outside face of convex tendon has upper and lower two inclined-planes, the plate face of described vehicle frame pipe and convex tendon lower inclined plane and journal stirrup reclines, be formed with an obtuse angle between the periphery of vehicle frame pipe and the convex tendon ramp, in this place, obtuse angle welding, vehicle frame pipe and journal stirrup are fixed together.
Adopt above technical scheme, because journal stirrup is provided with the convex tendon with upper and lower inclined-plane, the plate face of vehicle frame pipe and convex tendon lower inclined plane and journal stirrup reclines, and the area that one side vehicle frame pipe contacts with journal stirrup increases, and both are in conjunction with tightr; On the other hand, form the obtuse angle between the periphery of vehicle frame pipe and the convex tendon ramp, be easy to welding like this, and the welding dead angle is less, be difficult for producing slag inclusion, can guarantee the quality of welding.It is firm to be connected between journal stirrup and the vehicle frame pipe, has prevented that effectively journal stirrup is loosening or comes off, and has ensured the in-use performance of journal stirrup upper mounting component.
Above-mentioned convex tendon is formed by the direction punching press of journal stirrup towards the vehicle frame pipe, and the root on the upper and lower inclined-plane of convex tendon links to each other with the plate face of journal stirrup, passes through the cambered surface rounding off between the upper and lower inclined-plane of convex tendon.Above structure can make things convenient for processing and fabricating, can increase the rigidity of journal stirrup self again, prevents that journal stirrup from deforming or lose shape.
As preferably, the upper and lower inclined-plane of above-mentioned convex tendon equates that with angle between the otic placode face be 130～150 °, the angle between convex tendon ramp and the lower inclined plane is 80～120 °.
Beneficial effect: the utility model had both strengthened the intensity of journal stirrup itself by convex tendon is set on journal stirrup, made things convenient for welding processing between journal stirrup and the vehicle frame pipe again, and it is firm to make that both connect, and had avoided journal stirrup to deform, become flexible or come off.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model is made of journal stirrup 1 and vehicle frame pipe 2, and wherein journal stirrup 1 is a slab construction, and vehicle frame pipe 2 is a pipe.The middle part of described journal stirrup 1 forms a convex tendon 3 towards the direction punching press of vehicle frame pipe 2, and the axis of the length direction of this convex tendon 3 and vehicle frame pipe 2 in the same way.The outside face of convex tendon 3 is by ramp 3a, lower inclined plane 3b, the curved surface of cambered surface between upper and lower inclined-plane 3a, the 3b and upper and lower inclined-plane 3a, 3b end constitutes, the root of the upper and lower inclined-plane 3a of convex tendon, 3b links to each other with the plate face of journal stirrup 1, by the cambered surface rounding off, the end of the upper and lower inclined-plane 3a of convex tendon, 3b links to each other with the plate face of journal stirrup 1 by curved surface between the upper and lower inclined-plane 3a of convex tendon, the 3b.The upper and lower inclined-plane 3a of described convex tendon, 3b equate with angle between the journal stirrup 1 plate face, are 130～150 °, are preferably 141 ° in the present embodiment; Angle between convex tendon ramp 3a and the lower inclined plane 3b is 80～120 °, is preferably 99 ° in the present embodiment.The lower face of the periphery of described vehicle frame pipe 2 and convex tendon lower inclined plane 3b and journal stirrup 1 reclines, and is formed with an obtuse angle between the periphery of vehicle frame pipe 2 and the convex tendon ramp 3a, welds at this place, obtuse angle, and vehicle frame pipe 2 and journal stirrup 1 are fixed together.
As shown in Figure 5, journal stirrup 1 can be high-tension coil support 4 or driving engine bottom attachment point support 5 or rear brake main pump fixed support 6 or side cover support 7 or pressure regulator support 8 or back side cover fixed support 9 or back cover panel lower bracket 10, and vehicle frame pipe 2 is the pipe of corresponding site on the vehicle frame.The shape and the position of described high-tension coil support 4, driving engine bottom attachment point support 5, rear brake main pump fixed support 6, side cover support 7, pressure regulator support 8, back side cover fixed support 9 and back cover panel lower bracket 10 are prior art, and its structure is not done at this and given unnecessary details.
