A half shaft structure assembly and automobile

Abstract

The invention provides a half-shaft structure assembly and an automobile. The half-shaft structure assembly comprises a half-shaft body, a wheel speed gear ring arranged on the half-shaft body and a protection device arranged on the wheel speed gear ring in a sleeving mode. The protection device comprises a cylindrical device body, a first side edge and a second side edge, wherein the first side edge and the second side edge extend to the center of the cylindrical device body from the two ends of the cylindrical device body. The cylindrical device body is provided with a plurality of through holes. A gear on the wheel speed gear ring is clamped in the multiple through holes. The first side edge and the second side edge abut against the wheel speed gear ring. The protection device and the wheel speed gear ring are relatively fixed. According to the half-shaft structure assembly and the automobile, a gear ring opening is effectively filled and coated by arranging the protection device on the wheel speed gear ring in the sleeving mode, and knocking and damage of flying stone, sundries and the like to the gear ring are effectively avoided; after the gear ring is sleeved with the protection device, no opening exists, and the situation that foreign matter is clamped in the opening is avoided; and accordingly, a wheel speed sensor is effectively protected, and normal operation of the wheel speed sensor and the traffic safety are ensured.

Description

technical field [0001] The invention relates to the technical field of automobile parts manufacturing, in particular to a half-shaft structural assembly and an automobile. Background technique [0002] At present, the half shaft for automobiles is usually composed of a high-speed universal joint 1 and an intermediate shaft 2, and a wheel speed ring gear 3 is added to the outer end of the universal joint 1. Its structure is as follows figure 1 shown. For the half shaft of the above structure, the wheel speed ring gear 3 is in an exposed state. When the half shaft is running, if figure 2 As shown, the wheel speed sensor 4 recognizes relevant signals as the wheel speed ring gear 3 rotates. During the use of the above-mentioned ring gear structure, especially when the off-road vehicle is driving on muddy and gravel roads, the muddy water and small gravel driven by the high-speed rotation of the wheel are easy to hit the ring gear, causing the ring gear to break teeth, etc.; t...
