Drive axle shaft tube assembly for electric estate car

Abstract

The invention relates to a drive axle shaft tube assembly for an electric estate car and belongs to the technical field of electric car actuator parts and components. The assembly is composed of an elbow pipe, base plates, reinforcing ribs and damper supports and is characterized in that the base plates are symmetrically welded to the two ends of the elbow pipe, and at least four reinforcing ribs are welded to each base plate; reinforcing rings are welded to the rear portions of plate spring bases symmetrically welded to the elbow pipe, the damper supports are symmetrically welded to the elbow pipe, and a wire tube support is welded beside the damper support on one side of the elbow pipe. The assembly is high in mechanical strength, high in rigidity, low in mass, low in material consumption, low in cost and good in damping, denoising and braking effects; through the design of the elbow pipe with fall, stress is more uniform, the car can be effectively braked during fast traveling, and safety and steadiness of passenger-loaded operation are guaranteed. The problems of an existing drive axle shaft tube assembly for an electric car that mechanical strength and rigidity are low, mass is high, material consumption is high, cost is high, damping, denoising and braking effects are poor, and smooth, steady and safe passenger-loaded operation of the electric car can hardly be guaranteed are solved.

Description

technical field [0001] The invention relates to an electric station wagon drive axle shaft tube assembly, which belongs to the technical field of electric vehicle drive accessories. Background technique [0002] The shaft tube assembly is an important component of the drive axle and one of the main components of the driving system. It plays an important role in supporting and protecting the final drive, differential and half shaft. According to the planning objectives of the national "Energy Saving and New Energy Automobile Industry Development Plan (2012-2020)", more car companies will inevitably choose to develop new energy pure electric vehicles to reduce fuel consumption; at the same time, with the enhancement of people's environmental awareness , New energy pure electric vehicles are increasingly sought after by the public, becoming the first choice for people to travel and the future development direction of automobiles. However, in the current industrialization proce...

AI Technical Summary

Problems solved by technology

However, in the current industrialization process of electric vehicles, the shaft tube assembly of the chassis drive axle of electric vehicles has low mechanical strength and rigidity, heavy weight, troublesome disassembly and adjustment of the main reducer, large material consumption and high cost, resulting in reduced The vibration and noise reduction and braking effects are poor, and it is difficult to ensure the smooth and safe operation of electric vehicles with passengers
