Fault prewarning trailer axle

Abstract

The invention provides a fault early warning trailer axle, which belongs to automobile components, and in particular relates to an automobile trailer axle. The device comprises an outer bearing and an inner bearing which are sleeved on two ends of an axle, wherein hubs are sleeved on the outer bearing and the inner bearing respectively; a brake drum and the hubs are pressed together through bolts; a brake sheet is arranged on a brake bottom plate; the brake bottom plate is fixed on the axle; a camshaft is clamped by the brake sheet; the camshaft is movably arranged on the brake bottom plate; and an adjusting arm is sleeved on the camshaft. The trailer axle is characterized in that a heat sensor seat is arranged in a cavity formed by the brake drum and a dust cover; a heat sensor is arranged in the heat sensor seat; and the heat sensor is in electrical connection with a vehicle instrument panel. The trailer axle has the advantages that the heat sensor can rapidly sense the temperature change of the bearings and the brake drum in time, so as to effectively prevent axle overheat from damaging components, reduce the fault rate of vehicles, reduce the cost for maintaining and treating vehicle faults, prevent the brake sheet from being overheated and softened so as not to cause brake failure and guarantee driving safety; and the trailer axle is compact and reasonable in structure, easy to machine and implement, strong in practicability, stable in performance, safe and reliable.

Description

Technical field [0001] The invention belongs to automobile parts, and particularly relates to an automobile trailer bridge. Background technique [0002] The current automobile trailer axle is composed of axles, bearings, wheels, brake drums, brake bottom plates, and brake shoes. When the vehicle is running, the bearing temperature is too high due to lack of oil, damage or tight clearance, etc., which causes the bearing to burn out; especially when the vehicle brakes for a long time during a long-distance downhill process, it will brake. The temperature of the drum is too high, causing the bearing to burn out, the tire to burst, the brake drum to rupture, and the brake to fail. The occurrence of these faults will cause the car to break down and occupy the road, not only delays the delivery time, but also has to pay huge towing and maintenance fees, and even lead to traffic accidents that cause car crashes, and also affect the smooth flow of roads. Summary of the invention [000...

AI Technical Summary

Problems solved by technology

During the running of the vehicle, the temperature of the bearing is often too high due to lack of oil, damage or tight clearance of the bearing, which causes the bearing to burn out; especially when the vehicle brakes for a long time during a long-distance downhill process, the brake The drum temperature is too high, resulting in bearing burnout, tire burst, brake drum rupture, brake failure

The occurrence of these failures will cause the car to break down and occupy the road, not only delaying the delivery time, but also paying huge towing fees and maintenance fees, and even causing traffic accidents involving car crashes and fatalities, and at the same time affecting the smooth flow of roads
