Problems solved by technology

[0002] The development of electric vehicles has a history of nearly a hundred years, and hybrid vehicles have also undergone decades of development, but whether it is strong hybrid, medium hybrid, weak hybrid technology, or pure electric technology, they are basically based on The power transmission mechanism is arranged on the basis of the chassis frame of the vehicle, especially the design of the suspension mechanism and the power output structure of the vehicle is almost unchanged, so that the technology of electric vehicles and hybrid vehicles is not integrated in the design. The advantages of the vehicle are maximized, especially its vehicle suspension and its power output mechanism, which are often directly adopted from the design of old vehicles
Since the various functional parts of the old-fashioned suspension and its power output mechanism, such as shock absorption, steering, driving and other parts, have a certain separation in function, it will cause the entire structure to occupy a large space, so This mechanism is not suitable for electric and hybrid vehicles, especially when the energy density of batteries is still relatively low. The worse it is, the worse the economic benefit and competitiveness of the vehicle

Abstract

The invention discloses a drive axle for an electric vehicle or a hybrid electric vehicle. The drive axle comprises a motor stator, a differential, a driving conical gear, a damping steering shaft, a damping spring and a steering input conical gear, wherein the motor stator is fixed on a vehicle body; the differential is fixedly connected with a motor rotor; the driving conical gear is arranged at the output end of an axle shaft; the middle of the damping steering shaft is provided with a steering output conical gear; the lower part of the damping steering shaft passes through a shaft barrel;the shaft barrel is provided with a first conical gear and a second conical gear; the steering input conical gear is engaged with the steering output conical gear; a driving input conical gear is engaged with a first spline conical gear and a driving output conical gear at one end of a wheel driving shaft; and the other end of the wheel driving shaft is connected with wheels in a matching way. The drive axle has the advantages of compact structure, vehicle space saving, gear transmission among functional parts, high efficiency, long service life and convenient disassembly and maintenance.

Description

technical field [0001] The invention relates to a driving device component of a hybrid vehicle, in particular to a driving axle for an electric vehicle or a hybrid vehicle. Using the drive axle can greatly reduce the space required for the arrangement of the drive device in the car, reduce the weight of the vehicle, increase the number of batteries that the vehicle can carry, and modularize the design of the drive device so that it can be used in hybrid vehicles and four-wheel drive vehicles. There is a wide range of functions on the vehicle above the wheel. Background technique [0002] The development of electric vehicles has a history of nearly a hundred years, and hybrid vehicles have also undergone decades of development, but whether it is strong hybrid, medium hybrid, weak hybrid technology, or pure electric technology, they are basically based on The power transmission mechanism is arranged on the basis of the chassis frame of the vehicle, especially the design of th...
