A Double Bearing Weight Reduction Method for Full Suspension Rear Axle

Abstract

A double-bearing weight reduction method of a full-suspension rear axle is composed of a transmission half axle, an axle housing, a brake disc, a drum brake component, a locking round nut assembly, half axle nuts, a first bearing, a second bearing, a hole pattern check ring and a sealing ring. When a motor tricycle is loaded with weight, all the weight is acted on the drum brake and the axle housing component, so that force is transmitted to the half axle to drive the motor tricycle to travel, the load of the transmission half axle to the carrying weight is removed, thus operating efficiency is improved, and the service life of the transmission half axle is greatly prolonged. Meanwhile, accidental change occurs, shear force and impact force are dispersed onto the axle housing, the transmission half axle is prevented from bearing the shear force and the impact force during accidental change, half axle rupture is avoided, and the potential risks like a flywheel are also avoided. The structure is simple, the weight reduction effect is obvious, the safety coefficient for drivers and passengers is improved obviously, and the double-bearing weight reduction method of the full-suspension rear axle is suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of vehicle axles for elderly vehicles, in particular to a double-bearing weight reduction method for a fully suspended rear axle. Background technique [0002] At present, the rear axles of motorcycles are all tapered structures. Because of their simple structure, convenient operation, flexible driving, convenient use, and low price, they are deeply loved by elderly customers and are very convenient for travel or leisure use. However, due to the simple structure design, the rear axle adopts a single bearing. After the brake drum bears the gravity, the force is directly transmitted to the bearing, and then transmitted to the transmission half shaft through the bearing. All kinds of stress are far greater than other parts of the transmission system, which is easy to cause damage to the bearing. When the vehicle bumps during travel, the transmission half-bearing bears most of the load weight, and under the action of vari...

However, due to the simple structure design, the rear axle adopts a single bearing. After the brake drum bears the gravity, the force is directly transmitted to the bearing, and then transmitted to the transmission half shaft through the bearing. All kinds of stress are far greater than other parts of the transmission system, which is easy to cause damage to the bearing. When the vehicle bumps during travel, the transmission half-bearing bears most of the load weight, and under the action of various angles, the vehicle's The increase in transmission resistance and loss reduces the efficiency of mechanical movement, and the accuracy of the concentricity between the axle housing and the transmission half shaft is not high, which leads to the breakage of the transmission half shaft and the accident of the flywheel

[0003] The patent application number is 201020669553.3, which discloses an integrated motor-driven axle for electric vehicles. The brake drum is directly transmitted to the transmission half shaft after bearing gravity. Long-term use may easily cause the breakage of the transmission half shaft.
