CluthClutch assembly of front axle

Abstract

The invention discloses a cluthclutch assembly of a front axle, which comprises a top case and a bottom case which are connected with together. The top case is provided with a motor and a microswitch, and the bottom case is provided with a rack wheel and a rack shaft; the motor and the rack shaft are in a power connection through the rack wheel, and the gear rack wheel is linked with a volute spiral spring which is linked with the microswitch. After the optimization, one end of the rack shaft is stretched stretches outside the bottom case. The cluthclutch assembly of the front axle provided by the invention has the following advantages: the motor is not needed to frequently start or substantially work, so that the cluthclutch assembly of the front axle is more energy-saving and the damage of the motor is unlikely to cause; and in addition, an operator without higher skill can assemble the rack shaft and a gear sleeve shifting fork.

Description

technical field [0001] The invention relates to the technical field of motor vehicle components, in particular to a front axle clutch assembly. Background technique [0002] In a four-wheel drive vehicle, there are two drive shafts in the output of the transfer case: one to the rear axle and one to the front axle. In this way, when the motor vehicle is running, the transfer case transmits the power to the front and rear axles through the transmission shaft. In the case of 2WD, only power transmission to the drive shaft of the rear axle is required to drive the motor vehicle to run normally. In the case of bad road conditions or a lot of climbing loads, 4-wheel drive is required. At this time, the transfer case needs to transmit power to the front axle drive shaft through the transmission shaft at the same time, so the front axle clutch is required to switch the 2-wheel drive and 4-wheel drive of the motor vehicle as required. [0003] The early front axle clutch is a manu...

AI Technical Summary

Problems solved by technology

Its disadvantages are: 1. In the process of clutching, there will often be an unsuccessful situation. For this reason, the motor needs to be started continuously or continue to work until the clutch is in place, which not only wastes a lot of energy, but also easily causes the motor to burn out.

2. The rack shaft is located inside the housing, which requires extremely high assembly skills when assembling the rack shaft and gear sleeve shift fork

3. The power connection method of the motor through the large gear and the rack shaft is relatively complicated

4. In order to play the role of marking the initial position of the installation during assembly, and at the same time unload the need for compression of the scroll spring by the impact force after the normal operation of the motor and power off, the large gear is often equipped with gaps, which makes it easy to punch teeth during work. thus prone to damage

5. Scroll spring is easy to break
