Description
Technical field
The utility model belongs to the parts in the Automobile drive bridge system, is specifically related to a kind of little car drive axle wheel edge bearing support.
Background technique
Existing little car drive axle wheel edge bearing support only is used for installing and positioning bearing, and break then is installed on the bearing outer ring of wheel limit.Because bearing can produce vibration in the course of the work, and the formed jarring effect of this vibration long-term accumulation will cause installing the bolt looseness of break, thereby cause the faults such as break earlier period damage, seized, brake failure.In addition, because people are more and more higher to comfort and the reliability requirement of little car, therefore, need to abs sensor and inner oil seal be installed on the wheel limit, to prevent under severse weather, occurring phenomenon seized and the early stage leakage of oil in limit of vehicle bridge wheel.For this reason, need on ransaxle, be provided in addition installing the parts of abs sensor and inner oil seal, not only so that wheel limit complex structure, installing space are nervous, and increase cost of production.
Summary of the invention
The purpose of this utility model is for above deficiency, and a kind of little car drive axle wheel edge bearing support that bearing, break, abs sensor and inner oil seal can be installed on one and compact structure, good manufacturability is provided.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of little car drive axle wheel edge bearing support comprises the bearing support body that is provided with through hole, is provided with the bearing installing zone in the described through hole, and described bearing support body one end is provided with the brake backing plate of the first mounting hole bead is installed.
Described brake backing plate installation bead side is provided with the convex annular stopper for the brake backing plate radial location, and described convex annular stopper is positioned at the end outer rim of through hole one end.
Also be provided with the abs sensor installation base with jack and the second mounting hole on the described bearing support body.
Described through-hole wall is provided with the stepped a plurality of cylindrical grooves in cross section, and described bearing installing zone is positioned at the first cylindrical groove, and second cylindrical groove adjacent with the first cylindrical groove is the oil sealing installing zone.
Described abs sensor installation base is positioned at the upside of bearing support body.
The utility model by the bearing installing zone in the through hole and oil sealing installing zone and brake backing plate bead is installed respectively and the abs sensor installation base is installed on bearing, inner oil seal, break and abs sensor on the bearing support body, not only can reduce the quantity of part, reduce production costs, but also can improve the reliability of part, guarantee the abs sensor installation precision.Has compact structure, the characteristics of good manufacturability.Can realize radial location to brake backing plate by the convex annular stopper, thereby avoid causing the faults such as break earlier period damage, seized, brake failure to occur because of bear vibration.
