Waterproof wheel edge system for engineering mixer truck

Abstract

The invention relates to a waterproof wheel edge system for an engineering mixer truck. The system comprises an axle housing body, wherein the left end of the axle housing body is provided with a hub;the hub is sheathed with a brake drum; the outer wall of the right end of the axle housing body is connected with a space ring assembly; and the space ring assembly and the axle housing body are sealed through an O ring. The system can solve the following problems of an existing mixer truck waterproof wheel edge in a practical use process: 1) in an existing waterproof wheel edge, an independent hub oil seal is adopted to carry out a waterproof operation, dynamic lubrication sealing can not be realized in a use process, a situation of water leakage is liable to happen, and a waterproof effectis lowered; 2) after the hub and the axle housing body are simply isolated by the space ring, installation and connection are carried out, and a gap between the hub and the axle housing body needs tobe subjected to additional sealing processing; 3) a connection position between a half shaft and the hub is not subjected to the sealing processing; and 4) the brake drum and the hub are connected through a butt joint way, so that a stabilization effect is poor, and daily protection and maintenance is troublesome.

Description

technical field [0001] The invention relates to the technical field of vehicle waterproofing, in particular to a waterproof wheel edge system for an engineering mixer truck. Background technique [0002] The vehicle needs to be maintained regularly during daily use. Check the degree of wear of the vehicle and whether there is rust and corrosion inside the main parts. The daily maintenance of the hub is particularly important, especially when the mixer truck is often driven in a complex working environment. , the maintenance and protection of its hub is more important, so there is a waterproof wheel rim system in the existing vehicle hub. [0003] However, the following problems exist in the actual use of the existing waterproof wheels of mixer trucks. 1. The existing waterproof wheels use a separate hub oil seal for waterproofing, which cannot be dynamically lubricated and sealed during use, and water leakage is prone to occur 2. The wheel hub and the axle housing body are ...

AI Technical Summary

Problems solved by technology

[0003] However, the following problems exist in the actual use of the existing waterproof wheels of mixer trucks. 1. The existing waterproof wheels use a separate hub oil seal for waterproofing, which cannot be dynamically lubricated and sealed during use, and water leakage is prone to occur 2. The wheel hub and the axle housing body are simply installed and connected with a spacer ring, and the gap between the hub and the axle housing body needs to be sealed separately. 3. Between the half shaft and the hub There is no sealing treatment at the connection position 4. The brake drum and the wheel hub are connected by butt joint, the stability effect is poor, and the daily maintenance is more troublesome
