Description
Technical field
The utility model relates to automobile steering device technology field, especially a kind of Novel framework oil sealing of automobile steering device.
Background technique
The mechanical type commutator of existing automobile respectively uses a conventional outside framework oil seal to prevent the oil leak of commutator inner chamber at input end and output terminal.Oil sealing leakage of oil is the most common, the most incident a kind of failure mode of mechanical type commutator, and be one of the failure of removal of automobile factory and drivers headache the most, the remedial measure usually adopted changes oil sealing.A slight oil sealing part failure just directly causes automobile normally to run, and must stop the oil sealing pulled down commutator, remove part commutator part, could more renew, and whole process is time-consuming requires great effort again.
What redirector oil seal leakage of oil had appears at the automobile running initial stage, have appear at again the three guarantees phase after, studying carefully its failure cause has following factor: 1, the factor of oil sealing sizing material; 2, the factor of oil sealing sealing lip decrement; 3, the factor of oil seal structure; 4, the factor of automobile Environmental Conditions.At the initial stage of development of oil sealing, by commutator manufacturer and oil sealing supplier both sides type selecting, checking, adjustment sizing material, after general sizing sizing material, large problem would not be there is in oil sealing sizing material.And the factor of the structure of outside framework oil seal, lip decrement just becomes crucial factor.
The structure of the conventional outside framework oil seal that the existing whole nation each commutator manufacturer adopts in a large number is as shown in Figure 2: this conventional outside framework oil seal is made up of a dust-proof lip Φ D1 and seal lip Φ D2, be provided with a circle Compress Spring at seal lip place, by the compression of spring make seal lip hold tightly output shaft reach prevent commutator inner chamber lubricant oil toward the function of external leakage; Dust-proof lip can to prevent in automobile using process the foreign matters such as rainwater, the grains of sand, dust to invade oil sealing and damage seal lip.According to authoritative department statistics, (3 years or 50,000 kilometers) failure rate is up to 5% within the three guarantees phase for such conventional outside framework oil seal, and whole industry therefore direct economic loss surpasses more than 5,000 ten thousand yuan.Our unit's year use amount peak period reaches 700,000, and also loss is serious.
For the deficiency of above-mentioned existence, the applicant, through too much taking turns optimal design, succeeds in developing a kind of Novel framework oil sealing, greatly improves commutator skeleton oil seal performance.
According to retrieval, domestic not yet have the patent application identical with the utility model.
Summary of the invention
For the deficiency of above-mentioned existence, a kind of Novel framework oil sealing that the utility model provides a kind of automobile steering device, that be designed with two Compress Spring, double seal lips and dust-proof lip.
The utility model solves the technological scheme that its technical problem adopts: this kind of Novel framework oil sealing comprises oil seal body, skeleton, the first seal lip, the first Compress Spring circle, second lip of seal, the second Compress Spring circle, dust-proof lip, it is curl face that described oil seal body outer peripheral surface changes light face, and during protection oil seal pressing, outer ring is not sheared destruction; Described skeleton, by Chang for the widthwise edge Yan of its Γ type skeleton ╰ shape, improves outside framework oil seal intensity; The first described seal lip is arranged on the inner side end of Novel framework oil sealing; The first described Compress Spring circle is embedded in the first seal lip place excircle; Described second lip of seal is arranged on the end face outside of Novel framework oil sealing; The second described Compress Spring circle is embedded in second lip of seal place excircle; The built-in dust-proof lip that described dust-proof lip changes conventional outside framework oil seal is the dust-proof lip of external, and the dust-proof lip of this external is arranged on the outside of second lip of seal 5, passes the end face outside of Novel framework oil sealing.
Good effect of the present utility model is:
1. conventional outside framework oil seal only arranges a seal structures, i.e. a seal lip and adds a Compress Spring circle, and a kind of Novel framework oil sealing of the utility model arranges two seals lip and adds twice Compress Spring circle, adopts two seals structure, extend again the seal distance between two seals structure, the utility model sealing reliability is strengthened greatly.
2. oil sealing outer ring is interference fit with coordinating of oil sealing hole.Conventional outside framework oil seal outer peripheral surface is light face; the sizing material compressed when daily assembling is easily by hole wall scratch, shearing; and a kind of Novel framework oil-seal outer of the utility model side face to change light face be curl face, can not be destroyed extraordinary protection oil sealing outer ring during interference fit.
3. conventional outside framework oil seal structure adopts built-in dust-proof lip, seal distance is short, the outside foreign matter such as rainwater, the grains of sand, dust is very easy to invade oil sealing internal damage seal lip, cause seal failure, and a kind of Novel framework oil seal structure of the utility model adopts the dust-proof lip of external, outside the end face outside dust-proof lip being arranged on Novel framework oil sealing, and adjust dust excluder lips bicker degree, structure, prevent the outside foreign matter such as rainwater, the grains of sand, dust from invading more reliably, improve sealability.
4. a kind of Novel framework oil sealing of the utility model greatly improves sealing reliability, reduces seal failure rate, domestic and international automobile market of successfully supplying, and improve our unit's commutator quality of product prestige, overall economic efficiency is remarkable.
The utility model can extensively promote the use in all training gear of vehicle manufacturing enterprises.
