Abstract
The utility model discloses a kind of rack drives systems, including axle and it is mounted on the wheel at axle both ends, it further include rack drives gear, retarder and traction electric machine, the rack drives gear interference fit form is fixedly mounted in the middle part of axle, the shell of the retarder is embraced on axle by its two side bearing and axially position, the input shaft of retarder couples with the output shaft of the traction electric machine, and the transmission gear of retarder outputs it the output shaft that end tooth wheel and axle are assembled as retarder in the form of being interference fitted.The utility model is the utility model has the advantages that the vehicle equipped with this rack drives system can climb the rack rails route that line slope is greater than 40 ‰, convenient transportation is quick, in conventional track route of the gradient less than 40 ‰, also it can be realized inter-city rail transit transport, the composite transport for adapting to conventional line and rack rails route simultaneously, intensive, High aititude the tourist attraction traffic suitable for the volume of the flow of passengers.
Description
Technical field
The utility model relates to a kind of rack drives systems, are used for heavy grade rail vehicle transportation rack railway coach, belong to rail
Road technical field of vehicle.
Background technique
Existing railway track transit vehicle is only useful on track circuit of the gradient not higher than 40 ‰ and runs, with route
The gradient further increases, the driving accident that wheel and rail will have skidded.
Rack railway coach is a kind of rail transit train applied on rack-track, is greater than 40 ‰ gradients suitable for climbing
Steep gradient route.Rack drives system is installed on the bogie of rack railway coach, has following characteristics: weight is certain by two on vehicle
Steel wheel carrying on the common rail of gauge；Between two common rail be arranged a rack rails, wheel between be equipped with
The driving gear of rack rails engagement, provides tractive force and brake force for the vehicle on heavy grade track.
Utility model content
The goal of the invention of the utility model is: in view of the above problems, providing a kind of rack drives system.
The technical solution adopted in the utility model is such that
A kind of rack drives system including axle and is mounted on the wheel at axle both ends, further include rack drives gear,
Retarder and traction electric machine, the rack drives gear interference fit form are fixedly mounted in the middle part of axle, the retarder
Shell is embraced on axle by its two side bearing and axially position, and the output shaft of the input shaft of retarder and the traction electric machine joins
It connects, the transmission gear of retarder outputs it the output shaft that end tooth wheel and axle are assembled as retarder in the form of being interference fitted.
Preferably, the transmission gear of the retarder is second level or multi-stage speed-reducing gear forms.
Preferably, the tractive motor hanging is on the bogie of car.
Preferably, being installed in the form of being interference fitted between the axle and wheel.
Preferably, the bearing of the shell two sides uses tapered roller bearing.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1, the vehicle equipped with this rack drives system can climb the rack rails route that line slope is greater than 40 ‰, convenient transportation
Fast；In conventional track route of the gradient less than 40 ‰, inter-city rail transit transport also can be realized；
2, the composite transport of conventional line and rack rails route can be adapted to simultaneously；
3, suitable for the volume of the flow of passengers, intensive, High aititude tourist attraction traffic, rack railway coach can be handed over safely and fast
Logical transport.
Detailed description of the invention
Fig. 1 is the principles of the present invention schematic diagram.
Marked in the figure: 1 is axle, 2 be wheel, and 3 be rack drives gear, and 4 be transmission gear, and 5 be shell, and 6 be traction
Motor.
Specific embodiment
With reference to the accompanying drawing, the utility model is described in detail.
Embodiment:
As shown in Figure 1, a kind of rack drives system, including axle 1 and it is mounted on the wheel 2 at 1 both ends of axle, further includes
Rack drives gear 3, retarder and traction electric machine 6, the 3 interference fit form of rack drives gear are fixedly mounted on axle 1
Middle part, the shell 5 of the retarder is embraced on axle 1 by its two sides tapered roller bearing and axially position, retarder it is defeated
Enter axis to couple with the output shaft of the traction electric machine 6, the transmission gear 4 of retarder outputs it end tooth wheel and axle 1 with interference
Fit form is assembled as the output shaft of retarder.The traction electric machine 6 is suspended on the bogie of car.
The transmission gear 4 of the retarder is double-reduction gear form.
It is installed in the form of being interference fitted between the axle 1 and wheel 2.
In easy flights in, without rack rails, the tractive torque that traction electric machine 6 generates is transmitted on the track circuit of 40 ‰ gradients
Wheel 2 simultaneously contacts generation tractive force with rail；It is equipped with rack rails on the track circuit that the gradient is higher than 40 ‰ gradients and (is located at two
Among conventional rail), the tractive torque that traction electric machine 6 generates is transmitted to rack drives gear 3 and engages generation with intermediate rack rails
Tractive force.
