Embodiment
The utility model is described further in conjunction with attached drawing.
Embodiment 1
A kind of motor car bogie transmission mechanism, mainly by gear-box 6, sunpender 9, flap seat 11, active wheel disc 4, six-bar linkage machine
Structure 3, driven wheel disc 2 and axle 1 form.
In the present embodiment, 11 quantity of flap seat is 2, is installed on bogie frame crossbeam, gear-box 6 passes through two
Root sunpender 9 is suspended on flap seat 11, and the weight of gear-box 6 is passed to bogie frame and held by two groups of sunpenders 9 and flap seat 11
By.
One group of intermeshing big pinion gear and a hollow output shaft 5 are included in gear-box 6, wherein pinion gear is main
Driving wheel, gear wheel 7 are driven wheels.Gear wheel 7 is connected with output shaft 5, and at work, relative motion does not occur in both, it is preferable that
Connecting mode is key connecting.Output shaft 5 is by 8 fixed bearing of bearing at both ends, and bearing 8 is linked in the bearing of 6 babinet of gear-box
In bore, both ends by end cap closing and it is spacing.
One end of output shaft 5 is connected with active wheel disc 4, it is preferable that 5 end tube wall of output shaft is equipped with threaded hole, actively
4 correspondence position of wheel disc is provided with corresponding through hole, is connected with bolt therebetween.Also processed on output shaft 5 and active wheel disc 4 hinged
