Description
Technical Field
The invention relates to the technical field of rack rail vehicle driving, in particular to a rack rail wheel driving device and a bogie.
Background
The rack rail vehicle is fully researched at home and abroad, wherein a large number of physical locomotives operate on different mountain ground lines at home and abroad. Although a toothed rail vehicle running on a mountain land line is not available in China, similar technologies of the toothed rail vehicle have certain application in the fields of amusement facilities and coal mining. And in the patent field, a large number of tooth rail car patents are published in China. As is known from the state of the art, a rack wheel is arranged between the wheels, generally connected to the axle by an interference connection. The gear rail wheel and the wheel circle center are on the same height line and are relatively unadjustable. In order to ensure the normal meshing between the rack wheel and the rack on the line, the diameter use limit range of the wheel is very small, and is generally less than 10 mm. The wheel diameter use limit range of the common subway vehicle can reach 70mm generally. Due to the restriction, the replacement cycle and the service life of the wheel of the rack vehicle are seriously shortened, and the application range and the application performance of the rack vehicle are limited.
The Chinese patent application No. CN201910001264.1 discloses a rack wheel height adjusting mechanism and a rack wheel driving device provided with the same, wherein the height of a rack wheel relative to a wheel is adjusted by arranging the rack wheel height adjusting mechanism. When the wheel of the wheel pair is worn, the fixing of the adjusting ring and the frame is released, the eccentric wheel rotates anticlockwise for a certain angle to drive the rack wheel assembly on the hollow shaft to be lifted relative to the wheel pair, and therefore the relative height of the rack wheel and the wheel pair is changed. The device is not only complicated in structure, but also needs to dismantle the rack rail wheel, the hollow shaft head and the like when adjusting the height, the disassembly is complicated, the adjustment efficiency is low, and the operation efficiency of the rack rail vehicle is influenced.

As a further improvement of the above connection mode, the bottom of the axle suspension box has a second extending portion extending downward, and the first extending portion is detachably connected to the second extending portion through the first adjusting mechanism.
Preferably, the first adjusting mechanism is a first adjusting shim.
In order to further optimize the adjustment of the relative height between the output shaft and the central axis of the axle in the device, the driving device is hoisted below a framework of the rack car through a mounting piece, and a second adjusting mechanism for adjusting the relative height between the output shaft and the central axis of the axle is arranged between the mounting piece and the framework.
The driving device comprises a motor and a gear transmission mechanism in transmission connection with the motor.
The installed part is the jib, the motor pass through the jib with the framework can be dismantled and be connected.
The second adjusting mechanism is a second adjusting shim.
In order to ensure that the relative positions of the rack rail wheel and the wheel pair along the left and right directions of the rack rail vehicle are unchanged, the rack rail wheel is positioned in the center between the two wheels of the wheel pair.
The output shaft is preferably a hollow shaft.
As a general inventive concept, the present invention also provides a gear car truck comprising a frame and the above-described gear rail car wheel drive apparatus mounted on the frame.
Compared with the prior art, the invention has the advantages that:
the invention can realize the height change of the central line of the gear rail wheel relative to the central line of the wheel pair by changing the thickness of the adjusting pad. After the wheel is worn, the height of the rack wheel is reduced, the connection between the gear box and the axle suspension box is only needed to be removed, the connection between the suspension rod and the framework is also needed to be removed, and the adjusting gaskets with different thicknesses are replaced, so that the height of the rack wheel relative to the height of the wheel pair can be raised. By applying the device, the use limit range of the wheel diameter is expanded, the replacement period and the service life of the wheel are prolonged, and the use range and the use performance of the rack rail vehicle are expanded.

Detailed Description
The invention is further described below with reference to specific preferred embodiments, without thereby limiting the scope of protection of the invention.
Example 1:
as shown in fig. 1 and 2, the rack wheel driving device of the present embodiment includes a wheel set, a rack wheel 2, and a driving device for driving the rack wheel 2 to revolve.
The drive means comprise a motor 7, a gear transmission, and a gear box 6 on which the gear transmission is mounted. The motor 7 is connected with the framework 1 through a suspension rod 8 through a bolt, and a second adjusting gasket 9 is arranged between the suspension rod 8 and the framework 1. An input shaft of the gear transmission mechanism is connected with a motor 7 through a coupler, and one end of an output shaft 10 of the gear transmission mechanism fixes the gear rail wheel 2. The gear box 6 is mounted with the input shaft, the intermediate shaft and the output shaft 10 of the gear transmission mechanism in a shaft-surrounding manner.
The wheel set is arranged behind the gear box 6 and comprises an axle 11, wheels 12 which are arranged at two ends of the axle 11 in an interference mode, and an axle suspension box 3 which is arranged in an axle suspension mode with the axle 11, wherein the axle suspension box 3 is arranged between the two wheels 12.
The lower part of the side face of the gear box 6 opposite to the axle suspension box 3 is provided with a first extending part 61 extending backwards and downwards to the bottom of the axle suspension box 3, the bottom of the axle suspension box 3 is provided with a second extending part 31 extending downwards, and the first extending part 61 and the second extending part 31 are detachably connected through a connecting bolt 4. The first extension 61 and the second extension 31 are provided with a first adjustment shim 5.
The principle of adjusting the height of the rack wheel relative to the wheel in the embodiment is as follows:
when the wheel is worn, the height of the rack wheel 2 is also reduced synchronously. But the tooth top of the rack on the track can not be reduced relative to the track surface, and the generally allowed reduction height of the rack wheel 2 is 5mm, namely the diameter of the wheel 12 is worn by 10 mm. If the wheel 12 continues to wear, only the connection between the gear box 6 and the axle suspension box 3 and the connection between the suspension rod 8 and the framework 1 need to be released, and the first adjusting shim 5 and the second adjusting shim 9 are replaced, namely the thicknesses of the first adjusting shim 5 and the second adjusting shim 9 are changed, which is equivalent to that the relative heights of the rack wheel 2 and the wheel are changed, namely the rack wheel 2 is lifted, and the wheel 12 can be continuously used. By raising the rack wheel 2 multiple times, the service life of the wheel 12 can be extended. The thickness value of the first adjustment pad 5 can be accurately determined from the relative position and the amount of elevation.
The above description is only for the preferred embodiment of the present application and should not be taken as limiting the present application in any way, and although the present application has been disclosed in the preferred embodiment, it is not intended to limit the present application, and those skilled in the art should understand that they can make various changes and modifications within the technical scope of the present application without departing from the scope of the present application, and therefore all the changes and modifications can be made within the technical scope of the present application.
