Abstract
The utility model discloses a front damper for a motor tricycle, comprising a bumper assembly (1), a lower connecting plate (2) and a rocker arm assembly (3), wherein two ends of the bumper assembly (1) are respectively connected with one end of the lowering connecting plate (2) and one end of the rocker arm assembly (3); and the bumper assembly (1) is connected with the rocker arm assembly (3) by adopting a rolling friction structure. The front bumper has the advantages of being smart in structural design and convenient to install and manufacture. By adopting the front bumper, the bumping effect can be improved, the front bumper can be prevented from oscillating left and right in the running process of the motor tricycle, the stability of the motor tricycle is improved, the stress concentration of a lower connecting plate is lowered, and the service life and is prolonged, and the safety performance is improved.
Description
Technical field
The utility model relates to a kind of motor-tricycle, particularly a kind of front vibration absorber of motor tricycle.
Background technology
The utility model patent that a kind of name is called " motor-tricycle front damping device " is disclosed in CN201559773U, it comprises that the lower end of front fork tube, bumper is provided with U type damping rocking arm, hinged being connected of arm end of the lower end of front fork tube and U type damping rocking arm, another arm end of U type damping rocking arm is provided with the wheel shaft assembly opening, hinged being connected of down journal that the bottom between the lower end of bumper and U type damping rocking arm two arms is provided with.The hinged hole of down journal is not higher than the hinged hole of front fork tube and the wheel shaft assembly opening at U type damping rocking arm two ends.Though such structure may play the effect of damping, but in this utility model, in the lining of rocking arm one end, be provided with axle sleeve, be connected with crash bar by bolt then, when rocking arm rotates, be cliding friction between axle sleeve and the bolt, so just increased friction coefficient, reduced the effect of damping; Simultaneously, adopt welding manner to be connected between lower connecting plate and the front fork tube, cause stress concentration, weld nugget ruptures easily, has reduced the safety performance of front shock absorber.
The utility model content
The purpose of this utility model just provides and a kind ofly reduces friction, the front vibration absorber of motor tricycle of good damping effect.
The purpose of this utility model is to realize by such technical scheme, a kind of front vibration absorber of motor tricycle, comprise crash bar assembly, lower connecting plate and rocker arm assembly, the two ends of described crash bar assembly are connected with an end of lower connecting plate and rocker arm assembly respectively, adopt rolling friction structure to be connected between described crash bar assembly and the rocker arm assembly.
Further, an end of described rocking arm is provided with lining, is provided with bearing in this lining, and described rocking arm is connected with the crash bar assembly by the bolt that passes bearing.
Further, described bearing is two, is separately positioned on the boss two ends in the lining, and fixes by oil sealing.
In order to reduce stress concentration, described lower connecting plate two ends are connected with the crash bar assembly with bolt by the bolt hole that is arranged on the lower connecting plate respectively.
Owing to adopted technique scheme, the utlity model has the advantage that structure design is ingenious, installation is easily manufactured, adopt it can improve damping effect, prevented that front shock absorber from rocking from side to side in the process of moving, improved the stability of motor-tricycle, reduce the stress concentration of lower connecting plate simultaneously, improved service life and safety performance.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is an A portion amplification view among Fig. 2;
Fig. 4 is a B-B cutaway view among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail; but the utility model is not limited to these embodiments; any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, 2, 3, a kind of front vibration absorber of motor tricycle, comprise crash bar assembly 1, lower connecting plate 2 and rocker arm assembly 3, the two ends of described crash bar assembly 1 are connected with an end of lower connecting plate 2 and rocker arm assembly 3 respectively, adopt rolling friction structure to be connected between described crash bar assembly 1 and the rocker arm assembly 3.
Further, an end of described rocker arm assembly 3 is provided with lining 4, is provided with bearing 5 in this lining 4, and described rocker arm assembly 3 is connected with crash bar assembly 1 by the bolt that passes bearing 5.
Wherein, described bearing 5 is two, is separately positioned on boss 6 two ends in the lining 4, and fixes by oil sealing 7.
When front shock absorber was stressed, the rotation between rocker arm assembly 3 and the crash bar assembly 1 was undertaken by the friction of rolling of bearing 5, has reduced the friction force between them, damping effect has obtained reinforcement, adopts bearing 5 simultaneously, and precision is better, do like this, make bumper in the process of moving, stability is better.
As shown in Figure 4, described lower connecting plate 2 two ends are connected with crash bar assembly 1 with bolt by the bolt hole 8 that is arranged on the lower connecting plate 2 respectively.By the connection of bolt, reduced the stress concentration of lower connecting plate 2, make lower connecting plate 2 be difficult for stressed damage, improved the life-span of front shock absorber, also improved safety performance simultaneously.
