Abstract
The invention discloses a dust cover for a front swing arm of a minibus, which is provided with a dust cover main body (1) with an accommodating cavity (7). The outer wall of the lower end of the dust cover main body (1) is provided with a ring-shaped groove (4). The upper end of the dust cover main body (1) is provided with a sealing port (2). The sealing port (2) is communicated with the accommodating cavity (7) of the dust cover main body (1). An inner hoop (3) is embedded inside the upper end of the dust cover main body (1). The inner hoop (3) is surrounded around the sealing port (2). According to the invention, a unique closed-looped inner hoop structure is adopted to fasten the sealing port, so that not only is the labor intensity of assembly reduced, but also the assembling efficiency is improved. Moreover, the dustproof effect can be ensured and foreign matter and dust are effectively prevented from entering a pin head of a ball pin.
Description
Technical field
The present invention relates to a kind of microbus member, particularly the dust-proof cover of microbus front swing arm.
Background technique
The MacPherson type suspension is one of most widely used car forward mounting in the world today, is made up of swing arm under helical spring, vibration damper and the triangle.In microbus, swing arm is substituted by front swing arm and track bar under the triangle.Front swing arm ball pin is the vital part that front swing arm connects knuckle; Dust-proof cover guarantees the vitals of the normal operation of this part especially, and this dust-proof cover is sleeved on the ball pin bearing pin, and the sealed mouth inwall of dust-proof cover is the plane; And touch axle body; The two ends up and down of dust-proof cover respectively have an annular groove, block two annular grooves with two outer hoops with opening then, stop dust to get into the inner purpose of dust-proof cover to reach.Owing to need the later stage fastening between outer hoop and the dust-proof cover, not only the operation of assembling many (two outer hoops installations respectively), efficiency of assembling are lower, and the fastening force that outer hoop provided is difficult to guarantee.Particularly the corresponding fastening force that outer hoop provided in dust-proof cover sealed mouth outside is not strong, and the inwall of sealed mouth is the plane simultaneously, used of a specified duration after; The situation that the sealed mouth place fluffs can occur, dustproof effect will weaken, and causes foreign matter, water and dust to get into the pin head; Thereby influence the rotation of knuckle, cause motor turning ineffective, have potential safety hazard on the one hand; On the other hand, can quicken the wearing and tearing of ball pin, increase the maintenance and repair cost.
Summary of the invention
Technical problem to be solved by this invention is the microbus front swing arm dust-proof cover that provides a kind of dust and water protection effective.
Technological scheme of the present invention is following: a kind of microbus front swing arm dust-proof cover; Dust-proof cover main body (1) with band holding cavity (7); On the outer wall of dust-proof cover main body (1) lower end, have annular groove (4); The upper end of dust-proof cover main body (1) is provided with sealed mouth (2); Sealing mouth (2) communicates with the holding cavity (7) of dust-proof cover main body (1), is embedded with interior hoop (3) in the inside of said dust-proof cover main body (1) upper end, and hoop (3) is looped around the periphery of sealed mouth (2) in this.
The present invention is set on the ball pin, and the sealed mouth of dust-proof cover main body is close to the bearing pin of ball pin, and relies on the tension force banding of interior hoop; The pin head of ball pin is positioned at front swing arm, and this front swing arm is inserted in the holding cavity of dust-proof cover main body, by the outer hoop banding in the dust-proof cover main body lower loop connected in star.Compare with background technique, the present invention only need assemble an outer hoop, and the operation of assembling is few, has effectively improved efficiency of assembling; The sealed mouth of dust-proof cover main body provides fastening force by the interior hoop of dust-proof cover body interior; The fastening force that interior hoop provides is big; And it is constant that fastening force keeps; Can guarantee the situation that the sealed mouth place does not fluff, thereby ensure the dust and water protection effect, avoid foreign matter and dust to get into the pin head of ball pin.
Because the open type structure can fluff from opening after long-term the use gradually.Therefore, the closed loop structure that said interior hoop (3) is formed in one can keep constant tension power all the time, and is more durable in use.And the outer elastic hoop of tradition, similar elastic cord, the long-term use can be lax.
Inwall at said sealed mouth (2) has at least one " V " type annular groove; The inwall of sealed mouth is the sawtooth sealing configuration like this; After entangling ball pin bearing pin, the bearing pin axle body of tightly fitting after the hackle distortion, it is dustproof to form multilayer; Even the situation that certain one deck fluffs can not have influence on whole dustproof effect yet.
Beneficial effect: the present invention adopts the interior hoop structure of unique closed loop to come the fit sealing mouth, has not only reduced the labor intensity of assembling, has improved the efficient of assembling, and can guarantee the dust-tight effect, has prevented that effectively foreign matter and dust from getting into the pin head of ball pin.
Description of drawings
Fig. 1 is a sectional view of the present invention.
Fig. 2 is user mode figure of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
As shown in Figure 1, the present invention has dust-proof cover main body 1, and this dust-proof cover main body 1 is through molding and forming, and carries holding cavity 7, and the lower end of this holding cavity 7 is uncovered, and open-mouth is provided with the slightly little undergauge section of a diameter.On the outer wall of dust-proof cover main body 1 lower end, have annular groove 4, be used to install outer hoop.The upper end of said dust-proof cover main body 1 is provided with sealed mouth 2, and sealing mouth 2 is positioned at the top of holding cavity 7, and the lower end mouth of sealed mouth 2 communicates with the holding cavity 7 of dust-proof cover main body 1, and the upper end-hole of sealed mouth 2 connects the end face of dust-proof cover main body 1.Inwall at said sealed mouth 2 has at least one " V " type annular groove, and the number of " V " type annular groove is confirmed according to actual needs, is preferably two in the present embodiment.
From Fig. 1, can know, hoop 3 in the inside of dust-proof cover main body 1 upper end is embedded with, hoop 3 is looped around the periphery of sealed mouth 2 in this, and the closed loop structure that is formed in one of interior hoop 3.
Like Fig. 2 and combine shown in Figure 1ly, dust-proof cover main body 1 is set on the ball pin 5, and the sealed mouth 2 of dust-proof cover main body 1 is close to the bearing pin of ball pin 5, and the tension force lock ring that relies on the reaction force of deformation and the interior hoop 3 of sealed mouth 2 to form; The pin of ball pin 59 is positioned at front swing arm 8, and this front swing arm 8 is inserted in the undergauge section of dust-proof cover main body holding cavity 7, by outer hoop 6 bandings in the dust-proof cover main body 1 lower loop connected in star.
