Abstract

The utility model relates to a shock-proof tricycle, which belongs to the technical field of manpower driving tricycles. The shock-proof tricycle is characterized in that support plates are welded on bearing seats which are arranged on both ends of a rear axle; two bolts and two connection rods are fixedly connected to the bottom frame on both sides of a carriage; the lower end of the bolt is inserted into a sleeve; the lower end of the sleeve is connected with the support plate; springs are sheathed on the periphery of the bolt and the sleeve; the lower end of the connection rod penetrates through holes on the support plate, and protrudes from the lower side of the support plate to connect with positioning nuts; the spring is arranged on the periphery of the connection rod. The tricycle has the advantages of good shock-proof and shock absorption effect, hard damage of members, long service life, simple structure and low cost.

Description

Shock-proof tricycle

The utility model relates to manpower and drives the three-wheel vehicle field, exactly is Shock-proof tricycle.

Between current common manual tricycle case and the rear bearing block is directly to be welded by band iron, and therefore in motion, body vibrations is big, travel especially on relatively poor road surface, car body jolts seriously, damages member easily, and cargo-carring goods is also lost or damaged because of jolting simultaneously; The applicant once applied for a kind of damping three-wheel vehicle, application number: 96220943.0, though this design has shock-absorbing function, the space is arranged owing to adopt between the upper and lower hitching post, and wave easily during severe turbulence in travelling and damage spring to making.

The purpose of this utility model is in order to overcome the deficiency of prior art, a kind of shock absorption device that has to be provided, and the Shock-proof tricycle of easy damaged spring and member not.

The purpose of this utility model is achieved in that a kind of Shock-proof tricycle, by vehicle frame, wheel, railway carriage, rear axle, back plate, connecting rod and spring are formed, it is characterized in that being welded with back plate respectively on two top chocks at rear axle two ends, two symmetrical hitching posts and two symmetrical connecting rods are connected respectively in the middle part of the underframe of railway carriage both sides, the centre of sleeve epimere is inserted in the lower end of hitching post, hitching post is in sleeve on the energy, lower slider, the lower end and the back plate of sleeve are connected, be with spring around hitching post and the sleeve, the lower end of connecting rod is passed in the hole of back plate rear end, following and the setscrew nut of Extension support plate is threaded, and is with spring around the connecting rod.

The utility model has the advantages that: owing to adopt spring installation to substitute band iron supporting railway carriage, so when three-wheel vehicle travels, comparatively steady, particularly on rugged road surface, have shockproof preferably damping effect, protect the three-wheel vehicle member effectively, increase the service life; Simultaneously cargo-carring goods also is difficult for losing or damaging because of jolting; This apparatus structure is simple, and cost is low, is convenient to generally promote.

The A of accompanying drawing 2: Fig. 1 is to view;

Accompanying drawing 3: the utility model assembling scheme drawing.

Embodiment: vehicle frame 1, wheel 2, railway carriage 4, rear axle 6 and bearing seat 7 are the member of former manpower three-wheel vehicle, be welded with back plate 8 above the bearing seat 7 at rear axle 6 two ends, two symmetrical hitching posts 9 and two symmetrical connecting rods 11 are connected respectively in the middle part of the both sides underframe of railway carriage 4, the centre of sleeve 13 is inserted in the lower end of hitching post 9, hitching post 9 can be in sleeve 13 on, lower slider, the lower end of sleeve 13 is connected on the back plate 8, be with spring 10 around hitching post 9 and the sleeve 13, the hole at back plate 8 rear portions is passed in the lower end of connecting rod 11, and the following and setscrew nut 12 of Extension support plate 8 is threaded.Be with spring 14 around the connecting rod 11, when railway carriage 4 cargo are travelled, railway carriage 4 compression springs 10,14, and depress hitching post 9 and connecting rod 11, hitching post 9 glides in sleeve 13, connecting rod 11 lower ends glide in back plate 8 holes, when railway carriage 4 unloaded goods and is empty wagons, spring 10,14 resetted, hitching post 9 and connecting rod 11 along with on move, because spring 10,14 effects, three-wheel vehicle plays the function of shockproof damping.
