CN2271994Y - Damping tricycle - Google Patents

Abstract

The utility model relates to a damping tricycle, which belongs to the technical field of manpowered tricycles. The damping tricycle is characterized in that supporting plates are welded on two bearing seats on both ends of a back shaft respectively; two symmetrical upper bolts and two symmetrical connection rods are fixedly connected to the middle part of bottom frames on both sides of a carriage respectively; springs are sheathed on the peripheries of an upper bolt and a lower bolt; the lower end of the connection rod penetrates through holes which are arranged on the back end of the supporting plate and protrudes out the lower end of the supporting plate to connect with positioning nuts and pins; the spring is sheathed on the periphery of the connection rod. The device has shockproof and shock damping properties, which can be used for manually driven tricycles for carrying passengers and goods.

Description

The damping three-wheel vehicle

The utility model belongs to manpower and drives three-wheel vehicle, and specifically a kind of improved manpower that has shock absorption device drives three-wheel vehicle.

Existing common manpower drives three-wheel vehicle, comprise vehicle frame, wheel, compartment and driving and control part, since its railway carriage generally all by the direct cramp joint of band iron on railway carriage and bearing seat, so body vibrations is big when advancing, particularly be traveling on the relatively poor road surface, car body jolts seriously, damages parts easily, reduces service life; Cargo-carring goods is also easily lost or is damaged because of jolting simultaneously.

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of improved manpower that has shock absorption device to drive three-wheel vehicle.

Technical solution of the present utility model is: a kind of damping three-wheel vehicle, comprise vehicle frame, railway carriage, wheel, handlebar, rear axle and back axle bed, it is characterized in that: be welded with supporting plate respectively on two bearing seats in the two ends of rear axle, underframe middle part, railway carriage both sides is connected respectively two and is much of hitching post and two symmetrical connecting rods relatively, the vertical lower of last hitching post, the front end of the supporting plate following hitching post that is connected, on, between the following hitching post 1～4 centimeter gap is arranged, spring housing is last, around the following hitching post, the lower end of connecting rod is passed in the hole of supporting plate rear end, stretch out the following connection setscrew nut or the pin of supporting plate, spring housing is around connecting rod.

The utility model is owing to adopt springing to replace band iron supporting compartment, so, both made and be traveling on the relatively poor road surface, also has shockproof preferably damping performance, can protect parts effectively, increase the service life, can prevent effectively that also vehicle-mounted cargo from losing or damaging because of jolting in traveling process; This apparatus structure is simple simultaneously, makes easily, increase cost hardly, and it is light laborsaving to ride.

Below in conjunction with drawings and embodiments the utility model is described in further detail.
