A kind of automobile multifunctional driving axle

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, the use of new vehicle power devices), integrated 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 syst...

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
