Abstract

The invention discloses a rigid electric drive rear axle wheel rim assembly for a microcirculation vehicle, which relates to a wheel rim assembly. The assembly comprises a support frame, a hub and brake disc assembly, a bearing seat assembly, a hydraulic brake caliper assembly, a mounting plate, an ABS sensor and a bearing seat assembly, wherein the mounting plate is mounted on the support frame,and the hydraulic brake caliper assembly and the ABS sensor are mounted on the mounting plate; the bearing seat assembly comprises a bearing seat body, a unit bearing and a hole check ring, one end ofan inner hole of the bearing seat body is a bearing hole, the other end of the inner hole is a taper hole, and the bearing seat body is further provided with a groove in the outer end of the bearinghole; the unit bearing is installed in the bearing hole, the outer ring of the unit bearing is in interference fit with the aperture of the bearing hole, and the inner ring of the unit bearing is in interference fit with the hub and brake disc assembly; and the hole check ring is clamped into the groove of the bearing seat body. The rigid electric drive rear axle wheel rim assembly for a microcirculation vehicle has the characteristics of compact structure, short wheel rim maintenance period, high assembly precision, easiness in maintenance, high transmission precision, good product quality and the like, and can meet the development requirements of urban microcirculation buses.

Description

technical field [0001] The invention relates to a wheel rim assembly, in particular to a rigid electric drive rear axle wheel rim assembly for a microcirculation vehicle. Background technique [0002] The development trend of new energy vehicles has been expanding in recent years. With the vigorous promotion of green travel in the country and the continuous development of transportation planning, many large urban areas or communities are difficult to be effectively covered by public transportation. The residential areas and activity areas of large communities are far away from buses, subways, etc. The public transportation is far away, and the convenience of travel has become a difficulty. As a result, a "last mile" micro-circulation bus system for passengers came into being. This micro-circulation bus system solves the convenience of passengers' bus travel, improves the efficiency of passenger travel and bus operation, and solves the problem of long distances between commun...
