Description
Technical Field
The invention relates to an automobile driving part, in particular to a rear drive axle assembly of a light cross-country automobile.
Background
At present, the rear drive axle assembly of a light cross-country vehicle in China has a time-sharing four-wheel drive with electric drive and two-wheel drive and four-wheel drive switching, a time-sharing four-wheel drive with manual or automatic wheel-side clutch and two-wheel drive and four-wheel drive switching, a time-sharing four-wheel drive with vacuum brake drive and two-wheel drive and four-wheel drive switching, and a full-time four-wheel drive without two-wheel drive and four-wheel drive switching. However, the electric axle housing and the clutch are integrated into a whole, so that the structure is complex, the assembly and the maintenance are difficult, and the cost is relatively high; the two-wheel drive and four-wheel drive switching of the belt wheel side clutch increases the weight and unsprung mass of the whole vehicle; the automatic reliability is poor, and the manual selection and driving are inconvenient; the all-time four-wheel drive vehicle has high oil consumption and large resistance.
Disclosure of Invention
The purpose of the invention is: the rear drive axle assembly of the light cross-country vehicle has the characteristics of simple assembly and maintenance, lower cost, compact structure, convenient drive mode switching and good applicability.
The technical scheme of the invention is as follows: a rear drive axle assembly of a light cross-country vehicle comprises a rear drive axle and an external clutch assembly, the assembly is assembled on the rear drive axle through a mounting bracket,
the clutch assembly consists of a clutch and a power component, the power component comprises a box body and a box body cover, a motor is arranged in the box body, and a power output shaft of the motor is connected with a scroll bar; a duplex gear shaft is arranged in the box body, and a turbine and a gear are arranged on the duplex gear shaft; a gear shaft with a big gear and a gear is arranged in the box body; the rack shaft hole on the box body is provided with a rack shaft, the rack shaft is provided with a pin hole, and the shifting fork is arranged on the rack shaft through a pin.
The clutch comprises a shell, a clutch main shaft is arranged in the shell, a gear sleeve is sleeved outside the clutch main shaft, one end of the clutch main shaft is connected with a flange assembly, a clutch gear is arranged on the other side of the clutch main shaft, the clutch gear contains internal teeth, and the connecting flange is arranged on the internal teeth of the clutch gear through splines.
The worm is meshed with the worm wheel, the gear on the duplex gear shaft is meshed with the large gear, the gear on the gear shaft is meshed with the rack shaft arranged in the rack shaft hole on the box body, and the clutch gear is meshed with the clutch spindle through the gear sleeve.
The working principle of the invention is as follows: the motor receives the instruction back rotation of breaking away from, drives the turbine on the duplex tooth and then rotates through the worm on the motor shaft, then drives the rack axle through the epaxial gear of gear drive and realizes axial motion, lets clutch main shaft and clutch gear separate and hookup through installing the epaxial shift fork of rack at last to realize the separation and reunion of constant speed semi-axis and final drive, let the car carry out two and drive with four switching of driving.
Compared with the prior art, the invention has the following characteristics:
1. the clutch, the power assembly, the speed reducer, the drive axle housing and other elements are independent, the assembly and the maintenance are simple, and the cost is low.
2. The product has compact structure, makes full use of the leading action of the motor, realizes the disconnection and the combination through the switch control, ensures the high passing performance on a complex road surface, and also ensures the comfort and the low consumption at high speed.
