Further, described drive axle is provided with duplex bearing, described duplex bearing comprises bearing support, and be arranged on the bearing housing in described bearing support, and be symmetricly set on the tapered roller bearing of described bearing housing both sides, and be symmetricly set on the oil sealing outside described tapered roller bearing, and be symmetricly set on the fixing end cap of the both sides of described bearing support.When use, drive axle is used for driving front-wheel action by universal joint, owing to passing through universal joint transferring power, drive axle is easily subject to universal rotational, can produce and radially wobble, in order to meet the coaxality of engaging and disengaging gear, and due to drive axle limited space, so adopt duplex bearing, avoid adopting two problems that bearing installing space is inadequate.
The utility model working principle, shift fork and shift fork groove fit are installed, Joystick forward, guide rod moves backward, release lever moves backward along sliding sleeve, and shift fork drives shift fork groove mobile to the Compress Spring application of force backward, and the first flower keyboard moves backward, the first flower keyboard cooperatively interacting separates with the second flower keyboard, now can only drive main driving axle action; In the time that Joystick is pulled backward, forward, release lever moves forward along sliding sleeve guide rod, and shift fork moves forward, drive the first flower keyboard to move forward, the first flower keyboard is matched with the second flower keyboard, even if first, second flower keyboard can not be worked good at the beginning, the first flower keyboard is subject to responsive to axial force, coordinate the booster action of Compress Spring, finally can match with the second flower keyboard, after the one the second flower keyboards coordinate, the transmission of power of main driving axle is to drive axle.
The beneficial effects of the utility model are: control first, second flower keyboard freely deciliter by Joystick, transmit large moment of torsion; Overall structure is simple, takes up space little, is convenient to install, and the elastic force mate-assist Joystick of Compress Spring, the action of shift fork, ensure the cooperation between flower keyboard, and clutch is very convenient.
