Abstract
The utility model relates to a fast light weight cross-country bicycle which is characterized in that an A-type frame from a central axis to a rear axle is changed into a doorframe-shaped frame with light, and a chain wheel of a central axis is altered in the frame. In the middle of the central axis, a variable-speed shaft is added, which is provided with a big chain wheel and a small chain wheel. The utility model has the process that the chain wheel of the central axis drives the small chain wheel of the variable-speed shaft through a chain, and the big chain wheel of the variable-speed shaft drives flywheels of the rear axle. The driving speed is fast.
Description
The utility model relates to a kind of Mountain bike quick and portably.
At present, known bicycle all is the chain wheel on the axis, and directly the scrolling chain drives the flywheel on the car rear axle, and the chain wheel of axis is outside framework, must need the chain box, be centenary history, although done many improvement, but also have many shortcomings, it is tired that chain wheel is big, and chain wheel is little slowly.
The utility model purpose provides a kind of faster more than 1/2 than known bicycle, and is laborsaving more than 1/3, Mountain bike quick and portably, solve on and off duty, the slow shortcoming of going out.
The purpose of this utility model is achieved in that the A font framework of the axis of bicycle to rear axle, changes into bright door frame, makes the centre of axis chain wheel at axis.Middle increasing together or two road variable shafts, variable shaft has small one and large one chain wheel, and the chain wheel scrolling chain of axis drives the little chain wheel on the variable shaft, and the large toothed disk on the variable shaft drives the flywheel on the car rear axle, variable shaft is at the first half of framework, two bearing installation.For laborsaving, the chain wheel on the axis is not too big, and the little chain wheel on the variable shaft must be less than the chain wheel on the axis, and the large toothed disk on the variable shaft must also can add one variable shaft for faster again greater than the chain wheel on the axis.Axis respectively stretches out a pipe to the framework both sides of rear axle, is welded on the pipe, and the pipe that respectively stretch out in car rear axle framework front is welded on the pipe, and front and back form the equicrural triangle frame.A pipe is respectively welded on fork sleeve pipe both sides before the car, connects the below of axis framework to the pipe on seat pipe both sides.Respectively burn-oning one to manage and connect the pipe of axis framework both sides to seat pipe both sides in both sides, car front fork tube top, forms a cross shaped head.
Owing to adopted such scheme, make the speed of a motor vehicle faster, lighter when riding.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1: be the car constructional drawing
Fig. 2: be the framework with bright door of car axis to the car rear axle.
Fig. 1 (1) is axis and the bright door frame of rear axle band, and (2) are the arms that a pipe is stretched on rear axle framework both sides, and the arm of a pipe is stretched on (3) axis framework both sides, (4) be front fork sleeve pipe, (5) wheel.
Fig. 2 (1) is an axis, and (2) are the axis chain wheels, and (3) are variable shafts, the little chain wheel of (4) variable shaft, and (5) are the large toothed disks of variable shaft, (6) rear axle, (7) rear flywheel, (8) chain.
Realize that best way of the present utility model is to have adopted the method for changing speed that adds variable shaft, make Che Kuaigeng fast, lighter when riding.If fast again, also can use two variable shafts, but too fast, be best so use a transmission system.
Claims (2)
1, a kind of Mountain bike quick and portably is characterized in that: the frame type A from axis to the car rear axle becomes is with bright door frame shape, and the axis chain wheel is changed in the framework, in the middle of axis, has increased variable shaft again one simultaneously, and variable shaft has small one and large one chain wheel.
2, according to the described Mountain bike quick and portably of claim (1), it is characterized in that: the axis chain wheel drives the little chain wheel of variable shaft with chain, and the large toothed disk of variable shaft drives the flywheel of car rear axle.
