Abstract
The utility model relates to a bottom fork assembly of a two-wheel motorcycle; the two yokes of the bottom fork are parallel with each other and extend backwards; the two yokes are connected by a crossbeam; the utility model is characterized in that the yoke is provided with a rocker arm extending backward and askew upwards; a mounting hole is arranged on a top of the rocker arm.
Description
Technical field
The utility model relates to a kind of motorcycle accessories, particularly a kind of bottom fork assembly that increases the stroke two-wheeled motor vehicle of back damping.
Background technology
Motorcycle bottom fork is in the motor bike rear wheel to be connected to ground together, and by rear shock absorber the last bottom of can an attachment point on vehicle frame making certain limit with rear wheel is arrived, to slow down the vitals of the suffered impact of trailing wheel.In existing motorvehicle, wishing the simple while of body frame structure for automotive that can allow the space on the vehicle frame maximize the use again, damping generally is to be installed in the bar hole of chain stay end near upright form after two.Though this mounting means can make the space on the vehicle frame obtain utilizing, and is less near upright back damping stroke when driving, the weak effect of damping, driver and crew's traveling comfort is bad.
Summary of the invention
The purpose of this utility model is to provide a kind of bottom fork assembly of two-wheeled motor vehicle, and it can increase the stroke of back damping, good damping effect.
The purpose of this utility model is achieved like this:
The parallel side by side and extension to the back-end of two yokes of chain stay is connected with crossbeam between two yokes, and a described yoke is provided with the rocking arm of oblique upper extension backward, and the top of rocking arm is provided with mounting hole.
Described rocking arm and yoke are global formation, can strengthen the intensity of chain stay.
Since adopted such scheme, the parallel side by side and extension to the back-end of two yokes of the chain stay of two-wheeled motor vehicle, a described yoke is provided with the rocking arm of oblique upper extension backward, and the top of rocking arm is provided with mounting hole.By rocking arm, can make damping assembling back, back near straight, by this installation form, can increase the stroke of back damping, good damping effect.Owing to only a damping is installed and can reaches same damping effect, what therefore also increased simultaneously vehicle frame effectively utilizes the space, and removes and installs advantage easily in addition.
Be described further of the present utility model below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that A of the present utility model is to view.
Among the figure, 1,1 ' be yoke, 2,2 ' be mounting hole, 3 is crossbeam, and 4 is rocking arm, and 5 is bar hole.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the bottom fork assembly of two-wheeled motor vehicle, two yokes 1,1 of this chain stay ' side by side parallel and extending to the back-end, and yoke 1,1 ' between constitute the main bodys of chain stays with crossbeam 3 one-body molded backs.The rear end of described yoke is provided with the bar hole 5 that is used to install hind axle.The front end of yoke is provided with mounting hole 2, and this mounting hole is for installing the point of connection of bottom fork axis.Be provided with the Rocker arm 4 that oblique upper backward extends at described yoke 1, the top of rocking arm be provided with mounting hole 2 ', this mounting hole is for installing the point of connection of back damping.Described rocking arm and horizontal angle α are 20 °～50 °, and angle α can make the damping that is installed on the rocking arm reach preferable effect when 40 spend.
Rocking arm and yoke 1 are the global formation structure, to strengthen the intensity of Rocker arm 4.
