The invention relates to a novel-structure portal axle wheel side assembly which comprises a half shaft, a hub and brake disc assembly, a brake caliper, an air chamber assembly and a reduction gearbox assembly, the brake caliper is connected with the air chamber assembly, a mounting plate is fixedly arranged on a half shaft sleeve, the half shaft sleeve and the mounting plate are integrally cast to form an integrated half shaft sleeve, a bolt hole is formed in the mounting plate, an ABS support installation base is arranged on the installation plate, a bearing lubricating oil channel is formed in the installation plate and communicated with a shaft hole in the axle shaft sleeve, an oil receiving device is arranged in the bearing lubricating oil channel, an oil receiving hole is formed in the oil receiving device, and the oil receiving hole is communicated with the bearing lubricating oil channel. In the rotating process of an output gear in the reduction gearbox assembly, gear oil is thrown into and flows to a bearing through an oil receiving device, the bearing is lubricated and cooled, the gear oil finally flows back into the gearbox assembly through the bearing, and through repeated circulation of bearing lubrication and heat dissipation, the problem that the bearing fails in the early stage due to insufficient bearing lubrication can be effectively solved.
本发明涉及一种新结构门式桥轮边总成,包括半轴、轮毂与制动盘总成、制动钳、气室总成和减速箱总成,制动钳与气室总成连接,半轴套管上固定设置有安装板,半轴套管与安装板采用一体化铸造形成一体式半轴套管,安装板上开设有螺栓孔,安装板上设有ABS支架安装座,安装板上开设有轴承润滑油道,轴承润滑油道与半轴套管上的轴孔相贯通,轴承润滑油道中设有接油装置,接油装置上设于接油孔,接油孔与轴承润滑油道相贯通。减速箱总成内的输出齿轮转动过程中通过接油装置和把齿轮油甩入并流到轴承上,对轴承进行润滑、散热,齿轮油最终经轴承回流至齿轮箱总成内,经过轴承润滑、散热的反复循环,可有效解决轴承润滑不足导致轴承早期失效问题。
