The tricycle front damping device comprises dampers and a tricycle direction shaft (2), wherein the dampers are fixed on the lower portion of the tricycle direction shaft (2) through forge connecting plates (3), four dampers (1) are provided, and are divided into a front group and a back group, a damping spring (4) is sleeved outside each damper (1), two ends of the damping spring (4) are fixed through spring positioning sleeves (5), the spring positioning sleeve (5) is divided into an upper section and a lower section, one section is fixed on the forge connecting plate (3), and the other is fixed on the outer surface of the damper. The tricycle front damping device is convenient for installation, is applicable to various motor tricycles, is simple in structure, can be industrially produced, and is easy to be popularized.

Description

A kind of three-wheel vehicle front damping device

Technical field

The utility model relates to a kind of shock absorption device, a kind of three-wheel vehicle front damping device of saying so more specifically.

Background technology

Three wheeled motor car because turn to flexibly, use cost is lower, therefore is subjected to very much the people's of developing country welcome, particularly the mass peasants in the vast rural area of China.The major part of employed front shock absorber all is a damper on the current mobility three-wheel vehicle, but because the road conditions in present most of rural area are abominable relatively, and three wheeled motor car all is that loading is travelled usually, therefore front shock absorber not only is subjected to positive impulsive force when three wheeled motor car travels on such road surface, but also be subjected to very large side force, make front shock absorber be easy to deform, cause the cylinder type cylinder deformation, cause gas leakage or leakage of oil, and owing to be block distortion, can leakage of oil or gas leakage even change behind the seal ring still, its damping effect is reduced, even do not have damping effect fully, and service life is short, and the bumper that need more renew could continue to use.

The utility model content

The purpose of this utility model is to solve above-mentioned deficiency, provides a kind of carrying high, and has a kind of three-wheel vehicle front damping device of higher recovery.

For solving above-mentioned technical matters, the utility model by the following technical solutions:

Three-wheel vehicle front damping device of the present utility model, comprise damper and three-wheel vehicle axis of orientation, damper is fixed on three-wheel vehicle axis of orientation below by the forging connecting panel, and described damper is four, to guarantee balance support, and be divided into before and after two groups, each damper outside all is set with damping spring, and the two ends of damping spring are fixed by the spring locating bush, and the spring locating bush is divided into two joints up and down, one joint is fixed on the forging connecting panel, and another joint is fixed on the damper outside face.

Further technical scheme is: described damper is equally divided into two groups of front and back; Preceding two is that built-in valve is a damper, and latter two is the four-wheeled vehicle rear damper.

Further technical scheme is: described damping spring is sleeved on damper the upper half place.

Compared with prior art, the beneficial effects of the utility model are: device has guaranteed the balance and stability that shock absorption device is installed by 4 supports of four dampers, damping spring at the outside suit of damper is down auxiliary, can obviously reduce when three wheeled motor car travels vehicle body to impulsive force that damper produced, and then improve the three wheeled motor car bearing capacity, increased the service life of damper.Three-wheel vehicle front damping device of the present utility model is easy for installation simultaneously, is applicable to that various three wheeled motor cars use, and is simple in structure, can carry out suitability for industrialized production, is easy to promote.

Description of drawings

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

Fig. 2 is that the A of Fig. 1 is to scheme drawing;

Fig. 3 is that the B of Fig. 1 is to scheme drawing;

Fig. 4 is the L-L ' cutaway view of Fig. 1.

The specific embodiment

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

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model three-wheel vehicle front damping device, formed by damper 1 and three-wheel vehicle axis of orientation 2, damper 1 is fixed on three-wheel vehicle axis of orientation 2 belows by forging connecting panel 3, described damper 1 is four, and be equally divided into before and after two groups, preceding two is that built-in valve is a damper 11, latter two is a four-wheeled vehicle rear damper 12, each damper 1 the upper half suit stiffness is the damping spring 4 of K=13.27N/mm, and the two ends of damping spring 4 use spring locating bush 5 fixing, and spring locating bush 5 is divided into two joints up and down, one joint is fixed on the forging connecting panel 3, and another joint is fixed on damper 1 outside face.

When three wheeled motor car travels, the impulsive force that vehicle body produces shock absorption device the direction of passage axle, at first be that damping spring is to lower compression, when damping spring reaches capacity can't be again to lower compression the time, at this time damper 1 just moves downward under pressure, has realized having the three-wheel vehicle front damping device of dual damping effect with this.
