Detailed Description
The core of the application is to provide a bearing pressing plate, so that the assembly error is reduced and the strength is improved on the premise of ensuring that the outer ring of the half-shaft bearing can be prevented from being dust and pressed;
another core of the present application is to provide a drive axle having the bearing platen described above.
Hereinafter, embodiments will be described with reference to the drawings. Furthermore, the embodiments shown below do not limit the summary of the application described in the claims. The whole contents of the constitution shown in the following examples are not limited to the solution of the application described in the claims.
Referring to fig. 2, fig. 2 is a partial cross-sectional view of a driving axle according to an embodiment of the application.
The embodiment of the application discloses a bearing pressing plate 101 which comprises a bearing outer ring positioning part and a dust prevention part. The bearing outer ring positioning part is a main body part of the bearing pressing plate 101 and is used for pressing the outer ring of the half shaft bearing 103. The dustproof part and the bearing outer ring positioning part are of an integrated structure, and an inner hole of the dustproof part is used for being matched with the half shaft. The bearing pressing plate 101 is preferably an integral forging pressing plate, can have better strength through forging, effectively presses the half-shaft bearing, has better matching precision through machining a mounting surface, ensures dust prevention and water prevention, and only needs one part.
The bearing pressing plate provided by the application has the advantages that the bearing outer ring positioning part and the dustproof part are arranged into the integrated structure, so that the bearing pressing plate 101 has the function of dust prevention besides the function of positioning the bearing outer ring. By adopting the bearing pressing plate 101, a dust-proof plate in the prior art can be omitted, namely, the pressing plate and the dust-proof plate in the prior art are integrated into one part, one part is reduced, the structure is simpler, the assembly is easy, and the assembly precision is higher and the strength is higher due to fewer parts.
In one embodiment of the present application, the bearing outer ring positioning portion and the dust-proof portion are not in the same plane, and the bearing outer ring positioning portion and the dust-proof portion are connected through a transition portion. The bearing outer ring positioning portion needs to be attached and fixed on the end face of the sleeve flange 102, after installation, the dustproof portion is far away from the half-shaft bearing 103 relative to the bearing outer ring positioning portion, so that more installation space is reserved for other components, and of course, the dustproof portion can be arranged close to the half-shaft bearing 103 relative to the bearing outer ring positioning portion on the premise that the installation space is not considered. And the bending structure design is adopted, so that the strength is higher. The bearing outer ring positioning portion and the dust-proof portion may be in the same plane.
In one embodiment of the present application, the thickness of the plate of the bearing outer race positioning portion is greater than the thickness of the plate of the dust-proof portion. Because the bearing outer ring positioning part needs to be fixed on the sleeve flange 102, acting force exists between the bearing outer ring positioning part and the half shaft bearing 103, and a tiny gap exists between the dustproof part and the half shaft 104, the thickness design of the bearing outer ring positioning part is thicker, and the service life of the bearing pressing plate is prolonged. Because the problem of bearing clamp plate weight is considered, consequently select bearing outer lane location portion and dustproof portion to adopt the processing mode of different thickness, not only can guarantee the intensity of bearing clamp plate, can also reduce whole weight.
In one embodiment of the present application, the bearing outer race positioning portion is provided with a bolt hole for passing through the fixing bolt 106. The bearing outer race retainer may be mounted to the sleeve flange 102 by fixing bolts 106.
The embodiment of the application also discloses a drive axle, which comprises a sleeve flange 102 and a half shaft 104 arranged on the sleeve flange 102 through a half shaft bearing 103, and the application is mainly characterized by further comprising the bearing pressing plate 101 disclosed in the embodiment. The bearing pressing plate 101 is sleeved on the half shaft 104 and is fixedly connected with the end face of the sleeve flange 102, and specifically, the bearing pressing plate can pass through the bearing outer ring positioning part and the sleeve flange 102 through fixing bolts. Since the bearing pressing plate 101 disclosed in the above embodiment is adopted in the driving axle, all the technical effects of the bearing pressing plate 101 are achieved, and the description thereof is omitted herein.
In an embodiment of the present application, the present application may further include an oil seal 105 sleeved on the axle shaft 104, and the oil seal 105 is located between the bearing platen 101 and the axle shaft bearing 103, so as to further prevent muddy water from invading the axle shaft bearing 103. Further, the dust-proof portion is away from the half shaft bearing 103 with respect to the bearing outer ring positioning portion, and the width of the inner hole of the oil seal 105 is larger than the width of the outer peripheral surface. The larger the contact area between the oil seal 105 and the sleeve flange 102 and the half shaft 104, the better the sealing effect. However, the contact area between the oil seal 105 and the sleeve flange 102 cannot be made larger due to the influence of the space between the bearing pressing plate 101 and the half shaft bearing 103, and the contact area between the oil seal 105 and the half shaft 104 can be increased by extending the dust-proof portion in a direction away from the half shaft bearing 103.
In one embodiment of the application, the sleeve flange 102 is provided with a mounting for mounting a brake caliper. Preferably, the mounting block is of unitary construction with the sleeve flange 102. Because mount pad and sleeve flange 102 are integrated into one piece structure for the brake caliper can be directly installed on sleeve flange 102, thereby the use of intermediate junction spare has been cancelled, and in sleeve flange 102's production process, because the processing degree of difficulty that makes the parallelism between the different surfaces of single part is lower, so can fully guarantee the precision, thereby the furthest avoids the influence of assembly error to brake disc and brake caliper cooperation work, with the vibration noise that reduces disc brake and produce in the use, improved the result of use of disc brake on medium-and-small-sized car, especially SUV (Sport Utility Vehicle, sports utility vehicle) motorcycle type drive rear axle.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
