Embodiment
In order to the technical characterstic of clear explanation this programme, below by embodiment, and its accompanying drawing is combined, to this
Utility model is described in detail.It should be noted that part illustrated in the accompanying drawings is not drawn necessarily to scale.The utility model
Eliminate to known assemblies and known technology description, to avoid being unnecessarily limiting the utility model.
As shown in Figures 1 to 4, a kind of rear rocker arm of motorcycle device of liquid forging global formation, including rear arm 1, damping
Hanger 2 and pivot 3.Described rear arm 1 includes left arm 4 and right arm 5, is connected between the rear portion of the left arm 4 and right arm 5
After-poppet 6, left arm 4, after-poppet 6 and right arm 5 are configured to U-shape structure, and U-typed structural strength is higher, can avoid ride
The middle beat of rear arm 1, distortion, human pilot comfortableness are more preferable.Before being connected between described left arm 4 and the front portion of right arm 5
Support 7, left arm 4, after-poppet 6, right arm 5 and fore-stock 7 are configured to box structure.The damping hanger 2 is installed in the rear
On support 6, and positioned at the lower section of the rear arm 1；Due to more preferable using box structure, the mount point intensity of damping hanger 2.
Trailing wheel mounting hole 8 is equipped with the rear end of the left arm 4 and right arm 5, rear arm 1 passes through described trailing wheel mounting hole
8 are connected with the trailing wheel of motorcycle.Described pivot 3 is equipped with the front end of the left arm 4 and right arm 5, rear arm 1 is by described
Pivot 3 be connected with the engine of motorcycle.The rear portion of the right arm 5 is provided with brake limited block 9, and right arm 5 passes through brake
Limited block 9 is connected with the brake of motorcycle.Square deep gouge 10, square deep gouge are equipped with the positive and negative of brake limited block 9
10 can both meet that installation strength and installation dimension requirement, and can reduced casting flaw.The left arm rear portion is provided with chain regulator
Fixing point.The equal cross section of the left arm 4 and right arm 5 uses U-shape structure, and distinguishing uniform intervals on left arm 4 and right arm 5 is provided with 5
Bar reinforcement 11, rear arm 1 use reinforcement 11, that is, realize lightweight while also meet intensity requirement.Described damping
Hanger 2 includes shock-absorbing rocker arm 12 and shock-absorbing mounting hole 13, and the shock-absorbing mounting hole 13 is arranged on the outer end of shock-absorbing rocker arm 12, damping
