Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.
Referring to Fig. 1, spherical pin bushing assembly 100 of the present utility model includes spherical pin 10, ball seat 20, ball seat trim ring 30, housing the 40, first collar 50 and dust cover 60；Specifically, in the present embodiment, rubber bodies 80 it is arranged with on housing 40, being arranged with outer tube 90 in rubber bodies 80, preferably, rubber bodies 80 is positioned at the outside of housing 40, outer tube 90 is positioned at the outside as colloid 80, and vulcanize cementing between housing 40, rubber bodies 80 and outer tube 90 and make three be connected, so that it is guaranteed that fixing reliability, but do not illustrate with this and be limited.
Again as it is shown in figure 1, ball seat 20 is between spherical pin 10 and housing 40, and ball seat trim ring 30 is pressed on ball seat 20, and preferably, in the present embodiment, ball seat trim ring 30 is pressed on the top of ball seat 20, but does not illustrate with this and be limited.Dust cover 60 is placed on spherical pin 10, and one end of dust cover 60 is stuck on housing 40 or ball seat trim ring 30 by the first collar 50, and the other end of dust cover 60 engages with spherical pin 10.Wherein, the joint that spherical pin 10 engages with dust cover 60 offers annular groove 11, the joint that dust cover 60 engages with spherical pin 10 has the annular protrusion 61 coordinated with annular groove 11, one second collar 70 is stuck on dust cover 60 and makes annular protrusion 61 to be buckled in annular groove 11, so that dust cover 60 is more preferable with the joint sealing effectiveness of spherical pin 10, thus solves dust cover 60 and there is the problem leaking fat because of hardening at subcritical temerature.Will be understood that, the joint place that annular groove 11 can also be engaged with spherical pin 10 by dust cover 60 is formed, accordingly, the joint place that annular protrusion 61 is engaged with dust cover 60 by spherical pin 10 is formed, and equally reaches the purpose making dust cover 60 with the joint good sealing effect of spherical pin 10.More specifically, as follows:
Relatively the superior, the outside of dust cover 60 has the fastening groove 62 corresponding with the position of annular protrusion 61, fastening groove 62 and annular protrusion 61 is made to be positioned at sustained height, second collar 70 is buckled in fastening groove 62, so that annular protrusion 61 can be bound round in annular groove 11 by the second collar 70 more reliably；Specifically, in the present embodiment, dust cover 60 is cepaeform, and the cross section of annular groove 11 is arcuate structure, to increase the sealing effectiveness of dust cover 60 and spherical pin 10 further, stops the defect of dust cover 60 low temperature leakage fat；Certainly, in other embodiments, it is designed as other shape according to actual needs and by cross section and the dust cover 60 of annular groove 11, therefore is not limited with above-mentioned citing.
Meanwhile, the outside of dust cover 60 also has snap-in groove 63, and the first collar 50 is stuck in snap-in groove 63, so that the connection between dust cover 60 and ball seat trim ring 30 or housing 40 is more reliable.For example, in FIG, fasten the end of the one end being axially located dust cover 60 of groove 62 globally pin 10, and the end of the other end being axially located dust cover 60 of snap-in groove 63 globally pin 10, to reach compact purpose, but be not limited.
Furthermore, the first collar 50 and the second collar 70 are circular ring structure, to improve clamping effect and simple in construction；Preferably, as shown in Figures 3 and 4, in the present embodiment, the first collar 50 double-round circular ring structure, the second collar 70 is individual pen circular ring structure, further ensures that dust cover 60 connection reliability；Certainly, in other embodiments, it is designed as individual pen circular ring structure according to actual needs and by the first collar 50 and the second collar 70 is double-round circular ring structure, or, first collar 50 and the second collar 70 are both designed as individual pen circular ring structure or double-round circular ring structure, therefore do not illustrate with this and be limited.
Finally, as shown in Figures 1 and 2, spherical pin 10 is dome-type 10a for centre and structure that two ends are column type 10b, and annular groove 11 is formed on column type 10b；Specifically, in the present embodiment, a convex shoulder 12 is radially extended in the end of column type 10b, and annular groove 11 is opened at this convex shoulder 12, so can increase the degree of engagement after dust cover 60 is socketed with spherical pin 10, creates good conditions for improving sealing effectiveness.It will be appreciated that when annular protrusion 61 is formed on spherical pin 10, annular protrusion 61 now is positioned at the end of column type 10b.
To sum up, owing to the one in the joint of spherical pin 10 of the present utility model and dust cover 60 offers annular groove 11, another one in the joint of spherical pin 10 and dust cover 60 has the annular protrusion 61 coordinated with annular groove 11, one second collar 70 is stuck on dust cover 60 and makes annular protrusion 61 to be buckled in annular groove 11, make the dust cover 60 joint with spherical pin 10 at annular groove 11, the cooperation lower seal of annular protrusion 61 and the second collar 70 three is more preferable, solve the leakage fat problem that dust cover 60 occurs because of hardening when low temperature, thus improve the service life of spherical pin 10, and then guarantee the safety of automobile.
