Feature in example and embodiment can be combined with each other.It is below with reference to the accompanying drawings and in conjunction with the embodiments new this practicality is described in detail
Type.
Refering to Fig. 1, the steering gear dust cover of the embodiment of the present invention includes：Ontology 1；Wherein, the first connecting pin of ontology 1
A and the steering linkage 3 that is partially disposed in ontology 1 are combined together structure by vulcanization gelatinization joint.
Specifically, the first connecting pin a is cylindrical, and the first connecting pin a lateral walls are smooth.Compared with prior art,
It does not need to that additional clip is set to fix position-limit mechanism, such as card slot, simplifies dust cover and the knot at 3 cooperation of steering linkage
Structure has saved processing technology.
Preferably, adhesive linkage 2 is formed by vulcanization gelatinization joint technique between the first connecting pin a and steering linkage 3, such as can be with
Adhesive linkage 2 is formed by heat vulcanizate connection, adhesive linkage 2 can be made of vulcanization rubber.
When it is implemented, rubber cement is coated in the position that the first connecting pin a is in contact with steering linkage 3 first；Then, it uses
Fixture and vulcanizing equipment, depended on pressure compress dust cover and steering linkage 3, are heated to 190 DEG C, keep 1min, the after being heated
The interface that one connecting pin a is in contact with steering linkage 3 forms adhesive linkage 2, so as to which dust cover to be clinged to the table in steering linkage 3
Face；Finally, after testing, dust cover can bear the lateral force of 5kN.
Ontology 1 and adhesive linkage 2 can be made of rubber material, such as nitrile rubber, natural rubber, silicon rubber, poly- ammonia
Fat rubber, acrylic rubber, neoprene, fluorubber, ethylene propylene diene rubber, epichlorohydrin rubber etc..The material of steering linkage 3 can
Think 42CrMo steel alloys.
With continued reference to Fig. 1, the middle section of ontology 1 is a bellows segment, which has retractility, and the main buffering that rises is made
With, can effectively prevent dust cover both ends stress pull and to sealing effect generate harmful effect.
Steering gear dust cover that is above-mentioned obviously to obtain, being provided in the present embodiment, by by the first connecting pin of ontology 1
A is made of one structure with steering linkage 3 by vulcanization reaction, and bulb in steering linkage 31 is closely sheathed in splicing sleeve 5, is kept away
Exempt from rainwater, fog, foreign matter etc. to enter in steering linkage at bulb and splicing sleeve cooperation, with that in the prior art by clip will prevent
The end of dust hood is clamped on pull rod and compares, simple in structure, easy for installation and improve bulb and splicing sleeve in steering linkage and match
Leakproofness at conjunction.
