Detailed Description
The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, identical or similar reference numerals indicate identical or similar parts and features. The drawings are only schematic representations of the concepts and principles of embodiments of the disclosure, and do not necessarily show specific dimensions and proportions of the various embodiments of the disclosure. Certain features that are part of a particular figure may be exaggerated in order to illustrate relevant details or structures of embodiments of the present disclosure.
Referring to FIGS. 1-2:
example one
Novel sealed dustproof construction of direction machine of many footpaths of adaptation and multiple footpath, including being used for carrying out sealed dust-proof portion 7 to direction machine input shaft 4 on the direction machine body 1, dust-proof portion 7 is installed in the mounting hole 61 of automobile body panel beating 6, dust-proof portion 7 is including fixed suit in the inner bearing 73 in the direction machine input shaft 4 outside, the fixed suit in outer lane of inner bearing 73 has interior sleeve pipe 72, the fixed suit in the outside of interior sleeve pipe 72 has dirt proof boot 74, the outward flange of dirt proof boot 74 is fixed with the outer tube 75 with the concentric setting of dirt proof boot 74, the fixed suit in inboard of mounting hole 61 has outer bearing 71, the fixed suit in the outside of outer tube 75 of inner circle of outer bearing 71.
The outer bearing 71 and the inner bearing 73 are both bearings having self-sealing ends. The dust boot 74 is a corrugated bushing made of rubber material. The inner sleeve 72, the dust cover 74 and the outer sleeve 75 are vulcanized into a whole by rubber.
Referring to fig. 3, when the outer bearing 71 and the inner bearing 73 do not use a bearing with a self-sealing feature, further, an inner retainer 8 may be fixed to an upper end of the outer sleeve 75, and the inner retainer 8 may cover the upper end of the outer bearing 71. An outer retainer 9 is fixed to the upper end of the inner sleeve 72, and the outer retainer 9 covers the upper end of the inner bearing 73. Specifically, the inner retainer ring 8 and the outer retainer ring 9 are both made of plastic materials, and the inner retainer ring 8 and the outer retainer ring 9 are both arranged concentrically with the steering gear input shaft 4.
The working principle is as follows: specifically, a transmission part 2 is arranged on the steering gear box body 1, a steering knuckle connecting part 3 is arranged at the end part of the transmission part 2, and a steering column connecting part 5 used for being connected with a steering column bolt is arranged at the end part of the steering gear box input shaft 4.
When the steering gear box is used, a steering gear box is inserted into the steering gear box from the outside of the vehicle, an operator firstly coordinates the inner ring of the dustproof portion 7 with the steering gear box input shaft 4, the outer ring of the dustproof portion 7 is matched with the metal plate of the vehicle body metal plate 6 to be compressed, a limiting boss is arranged on the steering gear box input shaft 4 in the prior art, and the limiting boss can be automatically limited after the directional gear box is pressed in place.
Specifically, interior bearing 73 and 4 interference fit of direction machine input shaft, the external diameter and the 6 turn-ups interference fit of automobile body panel beating of outer bearing 71, direction machine input shaft 4 is when the pivoted like this, it rotates to correspond the bearing, dirt proof boot 74 is motionless, or the fine motion, the turned angle and the deflection of dirt proof boot 74 will be little like this, and then can improve the fatigue durability of product, because the specification of the bearing that adopts is different, just can use with multiple input shaft, and multiple automobile body hole site, make the sheath can be general. The dust-proof, water-proof and noise-reducing functions are achieved.
Further, the outer bearing 71 and the inner bearing 73 can be shielded by the arranged inner retainer ring 8 and the outer retainer ring 9 respectively, so that the dustproof effect is achieved, and the inner retainer ring 8 and the outer retainer ring 9 can be made of plastic materials.
Because the inner ring and the outer ring of the dustproof sleeve 74 are respectively matched with the inner bearing 73 and the outer bearing 71, the inner bearing 73 and the outer bearing 71 can be selected with different specifications, so that the product serialization is realized, and different vehicle types can be adapted through different selections of the inner bearing 73 and the outer bearing 71. The development of rubber molds can be reduced, and the cost is saved.
Exemplary embodiments of the proposed solution of the present disclosure have been described in detail above with reference to preferred embodiments, however, it will be understood by those skilled in the art that many variations and modifications may be made to the specific embodiments described above, and that many combinations of the various technical features and structures presented in the present disclosure may be made without departing from the concept of the present disclosure, without departing from the scope of the present disclosure, which is defined by the appended claims.
