Description
Technical field
The utility model relates to a kind of bicycle, is specifically related to the engineering plastics bicycle.
Background technology
Bicycle is China's the widest universal running vehicle, its owning amount be countries in the world.As with the non-motor-driven manned equipment in short interval, city, bicycle is cheap, convenient, body-building, environmental protection, energy-conservation characteristics are particularly outstanding, is can not obtain one of main traffic instrument that lacks and substitute now and even in longer time people life from now on.
Bicycle mainly has with lower component and consists of:
1, body part: comprising vehicle frame, front fork, handlebar, saddle and front forked assembly etc., is the main body of bicycle.Running part comprises pedal, crank, polyurethane synchronous belt, plastics synchronous pulley, axis and flywheel etc., steps on pedal by manpower, drives rotation of wheel by above Transmission, drives to move ahead.
2, undercarriage: namely front and back wheel, comprise antero posterior axis parts, spoke, wheel rim (rim), tire etc.
3, safety device: comprise drg (brake), car light, bicycle bell, reflective devices etc.
In addition, as required, also can increase some annexes, as support, clothes hanger, fork guard, mudwing, inflator etc.In addition, sporting car, sports car, mountain bike that speed-changing mechanism is housed etc. also is equipped with variable-speed controller and front rear derailleur etc.
The frame part of car body is the basic structure body that consists of bicycle, also skeleton and the main body of bicycle, miscellaneous part is all also directly or indirectly to be arranged on vehicle frame, due to bicycle be rely on the propulsive effort of human body self and by bike technical ability travel, can vehicle frame just become and bear the impact load that bicycle produces under steam and the important feature body that deliver comfortable, safely human body, the quality of frame part accuracy of manufacture will directly affect ride safe, steady and brisk.General spoke is isometrical, in order to alleviate gravity, also has and makes the reducing spoke that two ends are large, the centre is little, in order to reduce air resistance, spoke is made flat stream line pattern in addition.
At present, the vehicle frame of bicycle great majority adopt steel pipe, and its weight is very heavy, thereby has affected people's riding speed, and simultaneous reactions is underaction also, hommization not.
The utility model content
Slow for the riding speed that solves above-mentioned bicycle existence, as to react dumb and inadequate hommization problem, the utility model provides the engineering plastics bicycle.
In order to achieve the above object, technical solutions of the utility model are as follows:
The engineering plastics bicycle, comprise body portion, undercarriage and safety device, described vehicle body comprises saddle, handlebar, plastic wheel, flywheel and polyurethane synchronous belt, plastics synchronous pulley before and after described undercarriage comprises, described body portion also comprises a themoplasticity glass reinforced plastics vehicle frame and a themoplasticity glass reinforced plastics front fork, described vehicle frame joins by saddle pipe and saddle, and vehicle frame is rear wheel, flywheel and the themoplasticity glass reinforced plastics synchronous pulley of connection activation part respectively.Described front fork connection activation part front vehicle wheel and handlebar, and rotating being placed on vehicle frame.
Described bicycle also arranges a mudwing, and described mudwing and vehicle frame join.
The utility model is spry and light flexibly, has greatly improved riding speed.
Simultaneously, also greatly be reduced in the cost of expensive synthetic material aspect.
Description of drawings
Further illustrate the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model structural representation.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
The engineering plastics bicycle that the utility model provides comprises body portion, undercarriage and safety device.
Referring to Fig. 1, body portion comprises rear mudguard 1, saddle 2, saddle pipe 3, vehicle frame 4, handlebar 5 and front fork 8.
Undercarriage comprises front vehicle wheel 7, Timing Belt fluted disc 9, crank 10, pedal 11, Timing Belt 12, rear wheel 14 and flywheel 15.
Safety device comprises front brake 6 and back brake 13.
Wherein, front and back car 7,14 is taken turns and is plastic wheel; Timing Belt 12 is polyurethane synchronous belt.
Vehicle frame 4 adopts themoplasticity glass reinforced plastics, and it can give framework enough intensity, and anti-impact force is very strong, and is most suitable with its skeleton and main body as bicycle.
Simultaneously, the weight that it greatly reduces bicycle makes very light and flexible of bicycle, has improved the riding speed of bicycle, also greatly reduces productive costs.
In addition, but due to its thermoplastic shaping, can change according to customer's requirement the shape of vehicle frame, very hommization like this.
The upper end of vehicle frame 4 leading portions is flexibly connected by connecting bridge 5a and handlebar 4, and wherein, handlebar 4 is an expansion link, and the bicyclist can regulate height according to the situation of oneself.
The top in the stage casing of vehicle frame 4 is connected with saddle pipe 3, and connection is connected in the bottom with fluted disc.
Wherein, saddle pipe 3 is also an expansion link, and the bicyclist can regulate height according to the height of oneself, also is provided with a saddle 2 of correspondence with it on saddle pipe 3, above the bicyclist can be sitting in when riding.
