Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
Embodiment 1
As shown in Figure 1-2, a kind of large vehicle walking chassis of the utility model, including car body 1, one end installation of the bottom of car body 1
There is follower 3, the other end of the bottom of car body 1 is provided with driving wheel 2, and the inside of driving wheel 2 is provided with live axle 7, live axle 7
One end is connected with the output shaft of traveling reductor 6 by bellmouth taper, and the input of traveling reductor 6 is defeated with motor 5
Shaft is connected, and car body 1 is provided with branch free bearing 4 in the middle part of top.
Further, the bottom of the casing of motor 5 is connected vertically with the top of the casing of traveling reductor 6 by bolt, is subtracted
The axially mounted length of small running mechanism.
Further, traveling reductor 6 is K series large speed ratio Hardened gear face traveling reductors, extends traveling reductor
Life-span.
Further, driving wheel 2 and follower 3 are made of more than No. 45 cast steel materials, thick after blanks annealing
Processing, semi-finished product are handled through the second integral quenching, and hardness determination reaches HRC45~50 degree, then is installed and used after finishing, and prevents
Phenomena such as tread of driving wheel 2 and follower 3 wears and wheel rim turns up.
When specific, traveling reductor 6 and motor 5 are installed first, and being then set with connection traveling by bellmouth slows down
Machine 6 and live axle 7, it is that taper connect to make traveling reductor 6 and live axle 7, facilitate daily traveling reductor 6 installation and
Change, then chassis is put in orbit, now driving wheel 2 and follower 3 engage with track, when chassis when walking, drive
The tread of wheel 2 and follower 3 with track friction for a long time is possible to that abrasion or wheel rim can be caused to turn up, the driving wheel 2 of chassis
Do wheel body material using more than No. 45 cast steels with follower 3, roughing after rough annealing, semi-finished product through the second integral quenching at
Reason, hardness determination reach HRC45~50 degree, then installed and used after finishing, effectively prevent driving wheel 2 and follower 3 from existing
