Description
Technical field
It the utility model is related to a kind of bicycle with stepless speed change field, more particularly to a kind of bicycle with stepless speed change.
Background technology
Mainly on speed changer, speed changer is appropriate by selecting and adjusting for the difference of multi-speed bicycle and ordinary bicycle
Gear ratio user is more easily manipulated speed change system so that it is more quick and comfortable to ride.Variable speed in recent years
Bicycle because it is different from the transmission efficiency of additional fractionation multi-speed bicycle, rate adaptation can be continuously and adjustable range is big standby
By riding, fan is favored.
Bicycle with stepless speed change is equipped with buncher, therefore cost is higher, and because of its transmission efficiency, thus speed compared with
It hurry up, the operation intensity of vehicle body is larger.Therefore, in order to ensure the service life of bicycle with stepless speed change, the intensity of body structure will
Seeking Truth is high.In the prior art, the over-designed of part bicycle with stepless speed change body structure is outmoded, and structural strength is also difficult
To meet the high request of actual use.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of bicycle with stepless speed change, vehicle body knot
Structure intensity is high and fluent form is attractive in appearance.
To reach above-mentioned purpose, technical scheme is used by the utility model solves its technical problem：A kind of stepless change
Fast bicycle, including handlebar, front-wheel, vehicle frame, vehicle seat, step on device and trailing wheel, the vehicle frame include front fork from front to back, preceding
Pipe spreader, reinforcing thick stick, main thick stick, beam barrel, bearing pipe and a pair of back vents, the both ends of the main thick stick connect front axle sleeve pipe and axle respectively
Cylinder, the lower end of the beam barrel connection bearing pipe, it is in X fonts that the main thick stick intersects with reinforcing thick stick, the lower end differentiation for reinforcing thick stick
For a pair of preceding reinforcing pipes, a pair of preceding reinforcing pipes bend the bottom for connecting front axle sleeve pipe in arcuation and respectively, the main thick stick
Top and reinforce thick stick top between be connected with reinforcement transverse tube, the upper end of a pair of back vents and strengthen the upper end of thick stick and be all connected with
The middle part of bearing pipe is simultaneously interconnected.
Preferably, post-reinforcing short tube is connected between the top of a pair of back vents.
Preferably, being connected with seated pipe between the vehicle seat and bearing pipe, the seated pipe is in itself middle bent
And it is in zigzag.
Due to the utilization of above-mentioned technical proposal, the utility model has following beneficial effect compared with prior art：
1. setting the main thick stick and reinforcing thick stick to intersect in X fonts, the main load-bearing of car body is together constituted with bearing pipe
Structure, and the reinforcement transverse tube for connecting main thick stick top and reinforcing thick stick top is provided with, the stability of vehicle frame is further ensure that, is increased
The strong load-bearing property of this car, increases service life；
2. reinforce a pair of preceding reinforcing pipes that thick stick lower end differentiates connects front axle sleeve pipe respectively, main thick stick is all connected with admittedly with reinforcing thick stick
Due on front axle sleeve pipe, make foreside bodywork firmer；The seated pipe of below-seat is in be bent in zigzag in itself middle part, is carried
The high support performance of body in itself；The post-reinforcing pipe connected between the top of a pair of back vents is coupled and added for back vent
Gu avoiding a pair of back vents deviates from each other generation slight deformation, ensure user ride experience and safety it is unaffected；
3. reinforce thick stick lower end be divided into a pair of preceding reinforcing pipes respectively with front axle sleeve pipe connection and overall smooth curved, main thick stick
It is in X architecture with reinforcing thick stick, top is connected by the less reinforcement transverse tube of caliber, and moulding is unique smooth, is ensureing stabilized structure
On the basis of, vehicle body design novel and beautiful.
