Problems solved by technology

[0003] The purpose of the present invention is to provide an automobile multifunctional drive axle, to solve the problem that the brake cannot be braked under the condition of the automobile brake system failure, and then improve the safety of automobile driving
[0005] Aiming at the defect in the prior art that traditional fuel vehicles and new energy vehicles cannot perform normal deceleration and braking after the braking system fails, the applicant designed a new vehicle drive axle, that is, by setting a hollow bridge in the interior as a The main body support, the differential and the two drive shafts are all arranged in the hollow bridge, and when the main brake system of the car fails, the car cannot perform normal braking. At this time, the gear sleeve is driven to move by controlling the shift fork, and The tooth sleeves are respectively meshed with the main teeth and the secondary teeth, and under normal circumstances, the auxiliary brake components that are not connected with the two drive shafts and the differential are linked with each other, that is, the two drive shafts and the differential are rotating. At the same time, the torque is transmitted to the mechanical brake drum through the meshing between the secondary gear and the gear sleeve, the gear sleeve and the main gear, the main gear and the intermediate gear, and the intermediate gear and the generator gear. At the same time, the speed of the drive shaft After being transmitted to the generator teeth through the secondary teeth, gear sleeves, and intermediate teeth, the final mechanical brake drum rotation speed is greatly reduced through a multi-stage differential ratio. Similarly, after the main brake system fails, The driver only needs to perform a small manipulation of the auxiliary braking system to quickly reduce the speed of the drive shaft to achieve emergency braking of the car

Embodiment 1

[0028] like Figure 1~5 As shown, the present embodiment includes a hollow bridge 3, a differential device arranged inside the hollow bridge 3, and drive shafts 2 respectively arranged at both ends of the differential device. Basin teeth 31 are arranged on the outer wall of the differential device. The outer peripheral wall of each drive shaft 2 is provided with annular secondary teeth 20, and two toothed disc covers 15 are arranged inside the hollow bridge 3, and a bearing 16 is provided on each toothed disc cover 15. , the main tooth 17 is rotatably set in the bearing 16, and two intermediate pinion shafts 7 are rotatably arranged inside the hollow bridge 3, and an intermediate tooth 6 matched with the main tooth 17 is fixed on each intermediate pinion shaft 7. The outer wall of the hollow bridge 3 is provided with a case cover 12, and the part of the middle tooth 6 runs through the outer wall of the hollow bridge 3 and then extends towards the case cover 12. A mechanical ha...

Embodiment 2

[0034] like Figure 1~3 As shown, in this embodiment, on the basis of Embodiment 1, a drive box cover 23 is provided on the outer wall of the hollow bridge 3, and a central shaft, bearing II 25 and bearing III 33 are arranged in the drive box cover 23, and the central shaft One end of the shaft is rotated in the bearing II 25, and the other end of the central shaft passes through the outer wall of the bearing III 33 and the drive box cover 23 and then enters the hollow bridge 3, and the end of the central shaft is fixed with a tooth 31 matching the The angular gear 32 is provided with a drive gear sleeve 34 in the middle of the central shaft, and the drive planetary gear I 35 is fixed on the drive gear sleeve 34. A drive motor 37 is respectively provided on both sides of the drive box cover 23. The motors of the two drive motors 37 The drive shaft 21 respectively penetrates the two side walls of the drive case cover 23 and enters the drive case cover 23 , and the end of the mo...

Embodiment 3

[0036] like Figure 1~2 As shown, on the basis of Embodiment 1, the present embodiment is provided with a pull arm 41 on the lower surface of the hollow bridge 3 , and an adjusting hydraulic cylinder and a straight arm seat 46 are fixed on the bottom of the pull arm 41 . One end is hinged with the straight arm seat 46, and the output end of the adjustment hydraulic cylinder 47 is hinged with the middle part of the straight arm 45. On the other end of the straight arm 45, a brake air pump 42 is installed, and on the output end of the brake air pump 42 An emergency brake plate 43 is connected, and an emergency brake pad 44 is fixed on the lower surface of the emergency brake plate 43 . When the car performs emergency braking, the driver will be injured to a greater extent due to inertial factors, especially when the distance between the car and the car is large and the speed is fast, the main brake system cannot make effective braking, that is, the driving The probability of tr...

Abstract

The invention discloses an automobile multifunctional drive axle including a hollow bridge, a differential, and two drive shafts, the outer wall of the differential is provided with basin teeth, a bear is provided on each gear plate cover, the outer wall of the hollow bridge is provided with a box cover, a part of the middle teeth extends through the outer wall of the hollow bridge toward the inside of the box cover, a manipulator brake shaft is rotatably arranged in the box cover, a generator tooth is fixed at one end of the manipulator brake shaft, the other end of the manipulator brake shaft extends outward through the box cover, and a manipulator brake drum is arranged at the extension end of the manipulator brake shaft. The linkage between the drive shaft and the generator shaft is realized by the cooperation of the shift fork and the gear sleeve, in the case of failure of the main brake system of the automobile, the instantaneous stress of the cable in the auxiliary brake systemis prevented from causing the cable to break, the safety factor of the automobile in emergency is greatly improved, and the damage of the driver and the occupant is reduced to the minimum.

Description

technical field [0001] The invention relates to the field of new energy automobiles, in particular to an automobile multifunctional drive axle. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels and new vehicle power devices), and the comprehensive vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. The drive axle is one of the main components of new energy vehicles. Its function is to bend the power transmitted by the universal transmission through a 90-degree angle, change the direction of force transmission, and reduce the speed by the main differential. After increasing the torque , distributed to the left and right axle shafts and drive wheels through the differential, and when the car encounters an emergency, the driver on the way needs to use the brake s...
