Embodiment Construction

[0020] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0021] Such as figure 2 and image 3 As shown, the transmission axle of the present invention includes an axle housing 8, and an integrated transmission system integrating speed change, power transmission and driving functions is installed in the axle housing 8. The input shaft 1, the shifting device 2 and the differential 4, the output ends on both sides of the differential 4 are all connected with a power output device 6 through a reduction gear 5, the input end of the reduction gear 5 is connected to the output of the differential 4 The output end of the reduction gear 5 is connected to the input end of the power output device 6 . By integrating and installing the transmission system in the same axle housing as a whole, the speed change part and the drive part transmit power through the transmission gears that mesh with each other, so that it...

Abstract

The invention discloses a speed changing bridge which comprises an axle housing and an integral transmission system arranged in the axle housing, wherein the integral transmission system comprises a power input shaft, a gear shifting device and a differential mechanism which are sequentially connected by gears; and output ends at the two sides of the differential mechanism are respectively connected with a power output device. The speed changing bridge integrates a speed changing box, a transmission shaft and a drive axle into a whole, and the transmission system has the functions of changing speed, transmitting power and driving, so that the speed changing bridge has the advantages of being simple and compact in structure, fewer in parts, low in cost, smaller in occupied mounting space, short in power transmission route and high in transmission efficiency.

Description

technical field [0001] The invention mainly relates to the field of power transmission equipment for vehicles, in particular to a transmission axle that can integrate the functions of a gearbox, a drive shaft and a drive axle. Background technique [0002] The power transmission mechanism of a vehicle generally includes a gearbox, a drive shaft, and a drive axle. The gearbox is used to transmit power and change the speed ratio of the transmission system to obtain a larger driving speed range; To the driving axle; the driving axle is mainly used in the transmission system to realize the differential speed between the left and right driving wheels, and to further expand the deceleration range of the transmission system and increase the driving torque while transmitting power. In the traditional power transmission mechanism, the gearbox, drive shaft and drive axle are three independent components, such as figure 1 As shown, the traditional power transmission route is: engine→c...
