Abstract

The utility model relates to a tricycle, namely a front damping apparatus is additionally arranged between a tricycle frame of a manpower tricycle which is composed of a tricycle frame, front and rear wheels, a carriage, a drive device, etc. and a front wheel shaft; a rear damping apparatus is additionally arranged between the carriage and a rear wheel shaft, forming a novel damping tricycle. The utility model with the advantages of comfortable riding and bumpless feeling extends the service life of the tricycle and expands the use range of the tricycle.

Description

The damping manual tricycle

The utility model relates to a kind of tricycle.

Tricycle claims manual tricycle again, now is widely used in family and individual traders and pedlars, as small-sized transportation or people carrier.Its structure includes vehicle frame, front and back wheel, compartment and actuating device etc.Three-wheel vehicle is because of the car body broad, when travelling on non-standard highway or junior highway because the compartment is rigidly connected with under-carriage, thus jolt severity relatively, cause the discomfort of rider, and quickened the breakage of three-wheel vehicle, reduced service life.

The purpose of this utility model just provides a kind of manual tricycle with damping effect, rides comfort and prolongs the three-wheel vehicle life-span to overcome the existing structural deficiency of three-wheel vehicle, to improve.

The utility model is achieved in that existing and comprises installing damping device on the manual tricycle that vehicle frame, front and back wheel, compartment and actuating device etc. partly form, specifically be that the front shock-proof device device is housed between vehicle frame and front wheel spindle, the back shock absorbing apparatus is housed between compartment and hind axle.So just make manual tricycle have the damping effect of power actuated vehicle, thereby overcome the deficiency of original vehicle.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the front shock-proof device apparatus structure scheme drawing of three-wheel vehicle.

Fig. 3 is the end connection mode figure that goes up lower support plate behind the three-wheel vehicle in the shock absorbing apparatus.

Fig. 4 is that A-A of Fig. 3 is to cutaway view.

In Fig. 1, the three-wheel vehicle integral structure is identical with common three-wheel vehicle, promptly includes vehicle frame 3, front-wheel 1, trailing wheel 11, compartment 10 and actuating device.Front shock-proof device device 2 is installed between vehicle frame and the front wheel spindle, its concrete structure (as shown in Figure 2) is at the middle part of handlebar vertical rod 21 and lower end upper and

lower cover plate

15,20 to be housed, socket support tube 19 in the handlebar vertical rod between two cover plates, support tube is the part of vehicle frame, and it up and down is equipped with bearing and pays in two ends.Bearing is paid by bearing guard 16,

ball

17 and 18 sockets of axle bowl and is formed.Handlebar vertical rod 21 and lower cover 20 welding, its top are passed and are passed upper cover plate 15 again after support tube 19 and bearing are paid, by being equipped with jack panel 14 locking positionings.Two sleeve pipes 24 are housed on two cover plates, and the sleeve pipe upper end is passed upper cover plate by pull bar screw 22 and is fixed.Be with cramp bar 25 in the sleeve pipe, between cramp bar and the pull bar screw spring 23 arranged, the lower end and the front wheel spindle of cramp bar join.Like this, front wheel spindle and vehicle frame just join by the front shock-proof device device, and the shaking force of front-wheel is absorbed by damping spring 23.

In Fig. 1, the back shock absorbing apparatus of this three-wheel vehicle comprises two groups of upper and

lower back plates

5,9 that concave arc is relative, and every group of back plate can be the individual layer spring plate, also can be three to four layers of stacked formation of spring plate.The relative position place is fixed with spring perch 8 respectively on two back plates up and down, and spring 7 is loaded between two spring perches.Upper bearing plate 5 is fixedly connected with the compartment underframe by bearing pin and fixing chuck plate 6, be that fixing chuck plate 6 is fixed on the compartment underframe, and extend downwardly into the both sides of upper bearing plate 5, pass from the back plate bottom by bearing pin again and be fixed on the fixing chuck plate 6, thus fixing upper bearing plate.Lower support plate 9 is fixedly connected by fastener and under-carriage 13 and hind axle bearing 12.The type of attachment of upper and lower back plate end is shown in Fig. 3,4, and promptly its two ends loop-drive intussusception is fixed by the backplate 26 and the fastener 4 of both sides.Like this, the shaking force of trailing wheel is just by spring 7 and upward lower support plate absorption.

This novel damping three-wheel vehicle is ridden comfortablely, does not have the sense of jolting, and has avoided the rigid collision of body part, has prolonged service life.Simultaneously, this three-wheel vehicle has also played good buffer protection function to contained article, breakables Fit for Carrying, and range of use is expanded.
