Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
A wheel package assembly according to an embodiment of the present invention is described below with reference to fig. 1 to 18. The wheel package assembly may be applied to a rail vehicle 100 such as a straddle-type monorail vehicle. In the following description of the present application, the rail vehicle 100 is exemplified as a straddle-type monorail vehicle. Of course, it will be understood by those skilled in the art that the rail vehicle 100 may also be other types of rail vehicles and is not limited to a straddle-type monorail vehicle.
As shown in fig. 1 to 18, the wheel package assembly according to the embodiment of the present invention includes a sub through passage 21 and two wheel packages 31.
The wheel package assembly is suitable for covering the wheel set and connecting two adjacent vehicle bodies 1. Specifically, at least two vehicle bodies 1 are arranged in order along the longitudinal direction of the track vehicle 100. For example, in the example of fig. 1, three vehicle bodies 1 and two wheel package assemblies each connected between two adjacent vehicle bodies 1 are shown, each wheel package assembly comprising one wheel set, one through passage 2 and two wheel packages 31. It is understood that the specific number of the vehicle bodies 1 can be specifically set according to actual requirements to better meet practical application, and the number of the wheel package assemblies can be specifically determined according to the number of the vehicle bodies 1.
The sub through passage 21 is adapted to be provided on the upper surface of the vehicle body underframe 11 of the vehicle body 1. The two wheel packages 31 are suitable for being arranged on the upper surface of the vehicle body underframe 11, the two wheel packages 31 are arranged at two ends of the sub through passage 21 in the length direction of the vehicle body 1, and the two wheel packages 31 and the sub through passage 21 are jointly covered above the wheel set. Because two wheel packages 31 are respectively arranged at the front end and the rear end of the sub through passage 21, the whole structure is more compact, and the space utilization rate is higher. Here, it should be noted that the direction "forward" is understood to be the direction toward the front of the rail vehicle 100, for example, a straddle-type monorail vehicle, and the opposite direction is defined as "rearward", i.e., the direction toward the rear of the rail vehicle 100, for example, a straddle-type monorail vehicle. The two wheel packages 31 and the sub through passage 21 jointly separate the wheel set from the inner space of the vehicle body 1, thereby ensuring the safety of passengers. Moreover, by locating the two wheel packages 31 of the wheel package set on the upper surface of the vehicle body under-frame 11, the wheel package 31 occupies a smaller indoor area and provides better visibility and ventilation in the vehicle body 1, as compared to a conventional wheel package extending from the roof to the floor. In addition, the two wheel packages 31 can be used as special luggage racks, the permeability in the vehicle is not influenced, the space in the vehicle can be fully utilized, and the riding comfort of passengers is improved.
According to the wheel package assembly of the embodiment of the invention, when the wheel package assembly is applied to the rail vehicle 100 such as a straddle type monorail vehicle, by providing the sub through passage 21 and the two wheel packages 31 on the upper surface of the vehicle body underframe 11 of the vehicle body 1, arranging the two wheel packages 31 at both ends of the sub through passage 21 in the length direction of the vehicle body 1, and covering the two wheel packages 31 and the sub through passage 21 together above the wheel set, the occupied space of the wheel packages 31 is relatively small, thereby improving the in-vehicle permeability of the rail vehicle 100 such as a straddle type monorail vehicle.
According to some embodiments of the present invention, in conjunction with fig. 9 and 10, the sub through passage 21 is retractable. Alternatively, the entire through passage 2 is a bellows, and thus the sub through passage 21 may be a part of the bellows, and when the rail vehicle 100 such as a straddle-type monorail vehicle is operated, the sub through passage 21 may have a certain amount of expansion and contraction in the front-rear direction to ensure the normal operation of the rail vehicle 100 such as a straddle-type monorail vehicle. Here, it should be noted that the direction "forward" is understood to be the direction toward the front of the rail vehicle 100, for example, a straddle-type monorail vehicle, and the opposite direction is defined as "rearward", i.e., the direction toward the rear of the rail vehicle 100, for example, a straddle-type monorail vehicle. Of course, the present invention is not limited to this, and the sub through passage 21 may have another type of retractable structure, for example, the sub through passage 21 may have elasticity so as to have a certain amount of deformation in the front-rear direction. When the wheel set needs to be repaired and maintained, only the corresponding wheel packet 31 needs to be detached, or the telescopic sub through passage 21 is compressed to one side at the same time (as shown in fig. 10). When the wheel set needs to be disassembled, the wheel packet 31 can be disassembled firstly, then the sub through passage 21 is compressed towards the wheel packet 31 on the other side, and the space left after compression meets the space required by disassembling the wheel set. So, can realize maintenance and the dismouting to the wheel group in the car better, compare with the traditional mode of dismantling the wheel with the automobile body hoist in the vehicle section that has the line to hang, can save a large amount of manpower and materials, can further save the time of changing the repair again to the operation maintenance cost of whole car has further been reduced. In addition, the fasteners between the bogie 4 and the vehicle body 1 do not need to be disassembled and assembled, so that the reliability of connection between the bogie 4 and the vehicle body 1 is effectively ensured, and the service life is prolonged.
According to some embodiments of the present invention, referring to fig. 3, the top surface of the sub through passage 21 is flush with the top surfaces of the two wheel bags 31. In this case, the top surface of the sub through passage 21 and the top surfaces of the two wheel packages 31 are located in the same horizontal plane. With the arrangement, the space formed by the sub through passage 21 and the two wheel bags 31 can better cover at least two wheels 121 of the wheel set, the processing technology of the sub through passage 21 and the two wheel bags 31 is simplified, and the cost is reduced. According to a further embodiment of the present invention, the wheel package assembly further comprises: and a noise deadening member (not shown) provided between at least one of the wheel package 31 and the sub through passage 21 and the wheel set. That is, the noise dampers may be provided only between the wheel package 31 and the wheel set, or may be provided only between the sub through passage 21 and the wheel set, and of course, the noise dampers may be provided both between the wheel package 31 and the wheel set and between the sub through passage 21 and the wheel set. So configured, noise generated during operation of the rail vehicle 100, such as a straddle-type monorail vehicle, may be effectively reduced. Alternatively, the sound-deadening member is a sound-absorbing member (such as sound-absorbing cotton) or a sound-insulating member.
According to some embodiments of the present invention, referring to fig. 3-10, each wheel package 31 is removably connected to the vehicle body chassis 11 and the sub through passage 21. When the wheel 121 needs to be repaired and maintained, only the corresponding wheel packet 31 needs to be detached, or the retractable sub through passage 21 is compressed to one side at the same time (as shown in fig. 10). When the wheel 121 needs to be disassembled, the wheel package 31 can be disassembled firstly, then the sub through passage 21 is compressed towards the wheel package 31 on the other side, and the space left after compression meets the space needed by disassembling the wheel 121. So, can realize in the car maintenance and dismouting to wheel 121, compare with the traditional mode of lifting up the automobile body and demolising the wheel in the section of vehicle that has the line to hang, can save a large amount of manpower and materials, can save the time of changing the repair again, greatly reduced the operation maintenance cost of whole car. In addition, the fasteners between the bogie 4 and the vehicle body 1 do not need to be disassembled and assembled, so that the reliability of connection between the bogie 4 and the vehicle body 1 is ensured, and the service life is prolonged.

Alternatively, the plurality of threaded fasteners 313 are bolts or the like. In the description of the present invention, "a plurality" means two or more. For example, in the example of fig. 6-7, each mounting portion 312 may extend horizontally outward from a bottom edge of the wheel package 31 toward a direction away from a center of the wheel package 31. When mounted, the plurality of mounting portions 312 of each wheel package 31 are placed on the upper surface of the vehicle body under frame 11, and the plurality of threaded fasteners 313 may be threaded through the plurality of mounting portions 312, respectively, and the vehicle body under frame 11.

For example, referring to fig. 5, the edge of the sub through passage 21 and the mounting plate 5 are connected by a plurality of screw connectors, and the plurality of screw connectors are provided at intervals in the circumferential direction of the sub through passage 21. Alternatively, the plurality of threaded connectors are bolts or the like. Since the sub through passage 21 and the mounting plate 5 are detachably connected by a plurality of threaded connectors such as bolts, and the mounting plate 5 is detachably connected to the vehicle body under-frame 11, the sub through passage 21 can be detached, and the wheel 121 can be effectively detached from the vehicle. In addition, the sub through passage 21 is indirectly connected with the vehicle body chassis 11 through the mounting plate 5, so that the installation is firm, and the processing technology of the sub through passage 21 and the vehicle body chassis 11 is simplified. In addition, by adopting a mode of a plurality of threaded connecting pieces, the disassembly and assembly between the sub through passage 21 and the mounting plate 5 are simplified, and the cost is saved.
Alternatively, referring to fig. 4 and 5, the mounting plate 5 is a frame-shaped structure, and a plurality of threaded connectors are evenly spaced along the circumference of the mounting plate 5. For example, in the example of fig. 4 to 5, the mounting plates 5 are arranged in the vertical direction, and the mounting plates 5 are located at the edges of the sub through passage 21 and the corresponding wheel bags 31, so that the sub through passage 21 and the two wheel bags 31 can jointly define a mounting cavity for mounting the wheel set while ensuring that the mounting plates 5 are reliably connected with the sub through passage 21. The mounting plate 5 may be formed with a plurality of connection holes 51, wherein two connection holes 51 may be respectively located at two corners of an upper end of the mounting plate 5, another two connection holes 51 may be respectively located at an end portion of a lower end of the mounting plate 5, and the remaining connection holes 51 are respectively located between the four connection holes 51 and are uniformly spaced. Therefore, the whole mounting plate 5 is stressed uniformly, and the reliability of connection between the sub through passage 21 and the mounting plate 5 can be effectively ensured.

For example, referring to fig. 6, a side of each wheel package 31 facing the sub through passage 21 may be open, and a flange 311 is provided at an edge of the open side of each wheel package 31. During assembly, the flange 311 may be lapped on a side surface of the mounting plate 5 adjacent to the other wheel 31. Therefore, the sealing performance in the vehicle can be effectively guaranteed.
