Abstract

The utility model relates to a shock absorbing bicycle with shock absorbing function. The utility model which is used as a vehicle in the daily life of people is composed of a bicycle frame 5, a front wheel 8, a back wheel 1, a back fork 3, a front fork 7, a horizontal fork 13, a handle 6, a saddle 17 and a back saddle 16. One end of a shock absorber 11 is fixed on the front fork 7, and the other end of the shock absorber 11 is fixed on a bearing block 9. The right and left parts of the lower half section of the back fork 3 are replaced by shock absorbers 2 respectively, and the lower ends of the shock absorbers 2 are respectively fixed on a left and a right supporting seats 14. Because of the reasonable structural design and the proper shock absorbing intensity design of the utility model, the utility model which has the advantages of good shock absorbing performance and strong and beautiful external shape can effectively prolong the service life of a bicycle. The utility model is especially suitable for riding with heavy articles on uneven road surface.

Description

Damping bicycle

Use as the vehicle in a kind of people's daily life, have the damping bicycle of shock-absorbing function.

Bicycle is a kind of representative type vehicle, is applied at large in the life by people already.

Bicycle in the past has many types, and in men's style car is arranged, and woman style car has the loaded vehicle of adding, mountain bike, and the axle of quickening that also has that has reaches more multistage transmission system.But various bicycles in the past do not possess shock absorption device.Make people fully feel discomfort when riding on ripple road surface, mountain peak, especially when the user carries generation fearness mountain peak fearness shake article on the back with bicycle, more inconvenient.

The purpose of this utility model is to design a kind of bicycle with shock-absorbing function; it can conveniently be carried on the back act as what article; especially be afraid of the article of mountain peak, fearness shake; and; when on being winnowed with a dustpan in the road surface on the mountain peak, riding; greatly alleviate the mountain peak sense of winnowing with a dustpan, protect the rigidity structure of bicycle itself simultaneously, prolong the service life of bicycle.

Accompanying drawing is a structure principle chart of the present utility model, also is that specification digest is with scheming.Each label is respectively 1 rear wheel, 2 bumpers, 3 back vents, 4 hinges, 5 vehicle frames, 6 handlebars, 7 front forks, 8 front vehicle wheels, 9 bearing seats, 10 bearings, 11 bumpers, 12 bearings, 13 horizontal forks, 14 bearings, 15 carriages, 16 back seats, 17 vehicle seats among the figure.

As shown, the utility model is by vehicle frame 5, front vehicle wheel 8, rear wheel 1, back vent 3, front fork 7, horizontal fork 13, handlebar 6, vehicle seat 17, back seat 16 forms, wherein, each fixes a bar shaped bearing block 9 with bearing nut about on the bearing of front vehicle wheel 8, a bearing 10 is installed in the upper end of bearing block 9, the bottom of front fork 7 respectively with the axle gun iron link of the bearing 10 of the right and left together, damper 11 1 ends are fixed on the front fork 7, an other end is fixed on the bearing block 9, each replaces with damper 2 about 3 times halves of back vent, the lower end of damper 2 is separately fixed on the left and right sides bearing 14, bearing 14 is fixed together with nut with rear vehicle shaft, the parallel-segment of back vent 3 is connected with hinge 4 with ∧ type section joint, horizontal fork 13 both sides join with the bearing 14 of the right and left respectively, horizontal fork 13 flat pattern sections and ∧ type section joint join with a long vehicle axle 12, and carriage 15 cambers paste the rear upper rear that is welded in vehicle frame 5, and dickey seats in the holder of other end flat pattern.

Bumper 2,11 is piston, spring loaded piston, and its first half is a piston barrel, is piston in the tube, and piston rod is exposed at outside the tube, and spring one end is fixed on the piston barrel, and the other end is fixed on the piston rod;

The people rides the utility model when flat road surface is travelled, because of the intensity of bumper 2 and 11 is bigger, and imperceptible the trembling of the people that rides from bumper; When the people rode the scraggly road surface of the utility model process, bumper 2 just can be according to the different distortion that produce in various degree of fibrillation wave force amount with 11, and when bumper 11 distortion, bearing seat 9 and front fork 7 can produce a spot of angle variation along bearing 10; When bumper 2 distortion, bearing 12 and hinge 4 also can produce little rotation thereupon, thereby make full car reach the purpose of damping.

The utility model is because reasonable in design, and the damping Intensity Design is suitable, so it is good to have a damping performance, external form is strong, attractive in appearance, can prolong the service life of car effectively, be specially adapted to roughness pavement and carry on the back for riding than heavy articles, be another extremely promising newcomer in the bicycle family.

Embodiment:

With 28 bicycles is example, totally two of bearing seats 9, each long 80mm, wide 15mm, thick 5mm, respectively with about the cylindrical weld together of two bearings 10; About front fork 7 two bottoms respectively with about the axle weld together of two bearings 10, bumper 11 be about the piston spring formula each one, the diameter of piston barrel is 30mm+, long 100mm, thick 3mm, diameter of piston is 30mm-, and long 15mm, diameter of piston rod are 10mm, long 150mm, spring is a pressure-proof spring, and an end is welded on the piston barrel outer wall apart from piston tip 10mm place, and the other end is welded on the piston rod apart from piston-rod lower end 10mm place, spring is centered around the outside of piston barrel, diameter is 40mm, and the diameter of spring wire is 4mm, bearing 14 altogether about two, transverse part is of a size of wide 60mm, long 80mm, tiltedly portion's size is counted high 30mm from the transverse part top, wide 20mm, the oblique angle is identical with the oblique angle of back vent; The size of bumper 2 and bumper 11 measure-alike, about totally two, the one end is welded on the oblique portion summit of bearing 14, the bottom weld together of the other end and back vent 3, and hinge 4 is cover, bar structure, the diameter of bar is 12mm, hinge 4 replaces the back vent crossbeam, and long is 100mm, and bearing 12 selects for use 28 bicycle front axles to replace, be arranged between horizontal fork crossbeam and the back fender, horizontal fork can rotate around bearing 12.
