Description

Pedal assembly and through passage and vehicle comprising same

Technical Field

The present utility model relates to vehicles, in particular monorail vehicles, having a plurality of carriages. In particular, the present utility model relates to a step assembly between adjacent cars and to a through-passage and a vehicle including such a step assembly.

Background

Vehicles including multiple cars are often provided with through-passages between adjacent cars to allow personnel to move between the cars. The through-channel generally includes a bellows assembly and a tread assembly. The bellows assembly generally includes a main bellows and a bottom trim bellows connected to the main bellows on both sides of a lower portion of the main bellows. The pedal assembly is mounted in the lower portion of the through passage and is generally disposed substantially flush with the floor of the two compartments for covering the hinge or gap between the two compartments and for personnel to walk thereon.

A common through-passage pedal assembly includes a middle pedal, two side pedals, and two sets of linkages each consisting of four short bars and two long bars. The two ends of the long rod and the short rod are mutually hinged, the ends of the short rod are respectively and rotatably hinged on the end walls of the front and rear adjacent carriages after being hinged, and the two long rods are hinged in the middle and are connected with the middle pedal. Two (or two sets of) link mechanisms are respectively arranged at the left part and the right part of the middle pedal and the two side pedals. However, the structure uses two groups of link mechanisms, so that the occupied space is large, the structure of each group of link mechanisms is complex, the occupied volume is large, and the cost is high.

Moreover, the connecting profile of the bottom decoration shed of the existing through channel is formed by using a section of bent U-shaped profile, one end of which is connected with the clamping profile of the decoration shed by rivets, for example, and the other end of which is connected with the plate on the main folding shed by rivets, for example. The stability of the tail end of the clamping section bar of the bottom decoration shed is guaranteed through the U-shaped section bar, and the shaking and deformation of the clamping section bar are reduced. However, the U-shaped connecting section bar of the structure occupies a certain space, so that the U-shaped connecting section bar cannot be used on a vehicle model with a small space.

The structure of the conventional through passage has high space requirement, and cannot be applied to vehicle types with narrow space. For example, for monorail vehicles (e.g. straddle-type monorail vehicles), in particular monorail vehicles using jacob bogies, such as APM (automatic passenger shortcutting system) vehicles, the above-described structure cannot be used. These motorcycle types are the footboard assembly provides less space, can't set up the footboard assembly of above-mentioned structure, and U-shaped connection section bar occupies too big space and interferes with jacobian bogie moreover.

Accordingly, it is an object of the present utility model to address at least one of the above problems and needs in the art, and/or other technical problems.

Disclosure of Invention

According to one aspect of the present utility model, there is provided a pedal assembly adapted to be disposed between two adjacent cars, the pedal assembly comprising a first pedal, a second pedal, an intermediate pedal disposed between the first pedal and the second pedal, and only one linkage, wherein the first pedal, the second pedal are each connected to one of the two adjacent cars; the first pedal, the second pedal, and the intermediate pedal are respectively coupled to the link mechanism to be supported thereby and movable relative to the adjacent pedals.

In the above-mentioned scheme, since the pedal assembly only comprises one linkage mechanism, the occupied space is small, and the requirement on the installation space is not high, the structure of the pedal assembly in the scheme enables the pedal assembly to be suitable for vehicles with small space, such as monorail vehicles (e.g. APM vehicles), and preferably vehicles using Jacobs bogies (Jacobs bogies), wherein the linkage structure is not easy to interfere with the jac bogies.

According to one example, the linkage is configured as a four-bar linkage comprising a first bar, a second bar, a third bar, and a fourth bar, wherein the first bar and the second bar are hinged and coupled to the first pedal at their hinge locations, the third bar and the fourth bar are hinged and coupled to the second pedal at their hinge locations, the first bar and the third bar are hinged and coupled to the intermediate pedal at their hinge locations, and the second bar and the fourth bar are hinged and coupled to the intermediate pedal at their hinge locations.

The four-bar linkage in this example achieves support of the first pedal, the second pedal, and the intermediate pedal and achieves relative movement between the adjacent pedals with a simple construction, satisfying the need for movement deformation of the pedals during operation of the vehicle (particularly when the vehicle is traveling on a road condition of a small curve radius). Compared with the existing connecting rod mechanism consisting of two long rods and four short rods, the structure of the connecting rod mechanism is simpler, and the occupied space is smaller.

According to one example, the pedal assembly further comprises a support rod connected to the intermediate pedal and two sliders sleeved on the support rod to slide with respect to the support rod, wherein the hinge shafts of the first rod and the third rod are connected to one slider, and the hinge shafts of the second rod and the fourth rod are connected to the other slider.

In the scheme, the four-bar linkage is symmetrically arranged relative to the supporting rod, so that the self-adaptive centering of the pedal assembly is realized, and the stable and reliable running performance of the pedal is ensured while the running of the vehicle on a smaller curve radius is met.

According to one example, the pedal assembly further includes a support seat for supporting either the first pedal or the second pedal, the support seat being secured to the respective car and extending below the respective pedal to support the pedal.

According to one example, the support seats are plural to support the first pedal and the second pedal, respectively.

In the above example, the stable support of the first pedal and/or the second pedal is additionally realized through the support seat, so that the strength and the service life of the pedal assembly are improved.

According to one example, the support seat is configured as a sheet metal part having an overall U-shape and is fixed to the respective carriage at the closed end of the U-shape, and the two legs of the U-shape extend under the respective pedal to support the pedal. The support seat with the structure and the installation mode has higher strength, is more beneficial to supporting the first pedal and the second pedal, saves materials and reduces the weight of the pedal assembly.

According to one example, a limit mechanism is provided between the intermediate pedal and the first pedal and/or between the intermediate pedal and the second pedal, the limit mechanism comprising: a limiting pin arranged on the middle pedal; and a limit groove formed in the first pedal and/or the second pedal, respectively, wherein the limit pin is slidably engaged in the limit groove.

In this exemplary configuration, by the retaining pin sliding in the retaining groove, the pedal is restrained from lateral play while moving longitudinally (in the direction of travel of the vehicle), improving the stability of the pedal assembly movement.

According to one example, the two limit mechanisms are provided between the intermediate pedal and the first pedal and between the intermediate pedal and the second pedal, respectively, and the longitudinal directions of the two limit grooves of the two limit mechanisms are aligned in the traveling direction of the vehicle.

According to another aspect of the present utility model, there is provided a through-passage comprising a bellows assembly and a pedal assembly as described in accordance with the examples above.

According to one example, the through-channel is for a vehicle having a jacob bogie. Due to the adoption of the pedal assembly with the structures, the pedal assembly has the advantages of occupying smaller space and the like, does not interfere with the jacob bogie, and can solve the problem that the existing pedal assembly cannot be suitable for vehicles with the jacob bogie.

According to one example, the bellows assembly comprises a main bellows and two bottom decoration bellows connected to both sides of the lower part of the main bellows, respectively, wherein at least one bottom decoration bellows comprises a plurality of clamping profiles, a plurality of guide blocks connected to the lower ends of the clamping profiles respectively, and a rod coupled to one compartment, and the plurality of guide blocks are provided to pass through the rod and are slidable with respect to the rod.

In the example of this through channel, the centre gripping section bar end of bottom canopy overlaps on the pole that plays the stabilization effect through the guide block, can prevent when the vehicle passes through the curve, when the vehicle shakes or when there is the atmospheric pressure difference effect, the deformation or the rocking of bottom canopy's tip guarantees the firm reliability of bottom canopy and whole bellows assembly. Moreover, the installation space requirements are smaller than in the prior art in which a U-shaped connecting profile is used for connecting the fixed clamping profile, and can be applied in particular to monorail vehicles using jacob bogies, for example.

According to one example, the bottom finishing canopy further comprises a mount fixed to the one car and a ball pivot mount connected to the mount, wherein the rod is connected in the ball pivot mount. The hinge seat serves as a rod end joint bearing, so that the rod can rotate, thereby being suitable for various movements of the decoration shed.

According to one example, an end of the rod remote from the ball bearing is located in a bore provided in another car. The hole is reserved in the end wall of the carriage body, the part of the rod penetrating into the carriage body can slide in the hole, and the rod is prevented from being pulled out in the moving process of the carriage by setting the hole to have a certain depth and reserving a certain length in the hole. The hole may provide a reliable support and stop for the rod.

According to still another aspect of the present utility model, there is provided a vehicle including at least two compartments and a through passage according to any one of the above examples provided between adjacent two compartments. The vehicle is preferably a monorail vehicle. The above advantages of the tread assembly and through-passage of the present utility model are particularly pronounced when applied to monorail vehicles.

Detailed Description

The technical scheme of the utility model is further specifically described below through examples and with reference to the accompanying drawings. The following description of embodiments of the present utility model with reference to the accompanying drawings is intended to illustrate the general inventive concept and should not be taken as limiting the utility model.

Furthermore, in the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments. It may be evident, however, that one or more embodiments may be practiced without these specific details. Moreover, other structures and devices are not shown in the drawings to simplify the drawings.

Monorail vehicles are a common type of rail vehicle. Trains such as straddle-type monorail vehicles ride over rails, walk on concrete rails using rubber tires, and turn on both sides of the rails using auxiliary tires to maintain the balance of the vehicle. For vehicles using jacob bogies, the jacob bogies are disposed between two cars, occupying most of the space between the cars below the pedal surface. In addition to the conventional through-passage of such vehicles meeting the requirements for passenger safety, there is a need for shielding the jacob bogies to enhance the vehicle appearance. However, as an example, as shown in fig. 1, the through-passage of such a vehicle provides a smaller passing space 200 for the passenger and, correspondingly, a smaller installation space for the pedal assembly.

Such monorail vehicles (e.g., APM vehicles) can experience very severe small radius curve conditions (e.g., a minimum curve radius of 22 m) during normal operation, even with S-curve rail changes between stations. Therefore, the pedal of the through passage is larger than the movement of the pedal of a common light rail car and a subway when passing through a curve. Moreover, since for such monorail vehicles the path of small curve radius is a normal operating condition, the speed of the vehicle through the small curve reaches for example 15km/h, which also has a very high requirement for the stability of the pedal movement.

To this end, the present utility model provides a pedal assembly. An exemplary pedal assembly 100 is shown in fig. 2, 5-7 and includes a first pedal 1 and a second pedal 2 each hinged to a body end wall (not shown) of two adjacent cars, and an intermediate pedal 3 disposed between the first pedal 1 and the second pedal 2. The intermediate pedal 3 may partially overlap the first pedal 1 and the second pedal 2, respectively, thereby forming a floor on which a passenger can tread. The pedal assembly 100 is characterized in that it comprises only one linkage 4 (see fig. 6), which single linkage 4 can be arranged on the back side of the first pedal 1, the second pedal 2 and the intermediate pedal 3 (i.e. the surface of the pedals facing away from the cabin interior space) and is coupled to all three pedals 1, 2, 3 in order to provide the three pedals with freedom of movement at the same time. The use of a single linkage has the advantage of less space occupation and less space requirements than existing arrangements using two or more linkages to support the pedal assembly. The construction of the pedal assembly in this solution thus enables the pedal assembly to be adapted to vehicles of small installation space, such as monorail vehicles (e.g. APM vehicles), preferably for vehicles using Jacobs bogies (Jacobs bogies), wherein the linkage does not interfere with the Jacobs bogies below the pedal face.

As shown in fig. 5 to 7, the link mechanism 4 is configured in this example as a four-bar mechanism including a first bar 41, a second bar 42, a third bar 43, and a fourth bar 44 of the same length, the four bars being connected end to end by a pin and rotatable about the pin. Wherein the first and second rods 41, 42 are hinged and connected to the first pedal 1 at their hinge points by means of a mounting, and the third and fourth rods 43, 44 are hinged and connected to the second pedal 2 at their hinge points by means of a mounting. So that the first and second levers 41 and 42 can rotate relative to the first pedal 1, the third and fourth levers 43 and 44 can rotate relative to the second pedal 2, and support of the first and second pedals 1 and 2 is achieved at the respective hinge points. Compared with the existing connecting rod mechanism consisting of two long rods and four short rods, the four-connecting-rod structure is simpler in structure and smaller in occupied space.

As shown in fig. 7, the pedal assembly further includes a support rod 5 connected to the intermediate pedal 3 through two connection blocks 51 at both ends, and two sliders 6 fitted over the support rod 5 to slide with respect to the support rod 5. The hinge shafts of the first lever 41 and the third lever 43 are connected to one slider 6 (the slider on the left in fig. 7), and the hinge shafts of the second lever 42 and the fourth lever 44 are connected to the other slider 6 (the slider on the right in fig. 7). The two hinged ends of the linkage are thus respectively slidingly connected to the support bar 5 and support the intermediate pedal 3. By means of the structure, the four-bar linkage mechanism 4 is symmetrically arranged relative to the supporting rod 5, so that self-adaptive centering of the pedal assembly is achieved, and stable and reliable pedal operation performance is guaranteed while the vehicle runs on a smaller curve radius.

As shown in fig. 7, a stopper mechanism is also provided between the intermediate pedal 3 and the first pedal 1, and between the intermediate pedal 3 and the second pedal 2, respectively, the stopper mechanism including a stopper pin 31 provided on the intermediate pedal 3 and stopper grooves 10 formed in the first pedal 1 and the second pedal 2, respectively, wherein the stopper pin 31 is slidable in the stopper grooves 10. The limiting pin slides in the limiting groove, so that the pedal is limited to transversely move while relatively moving in the longitudinal direction (in the advancing direction of the vehicle), and the stability of the movement of the pedal assembly is improved. Advantageously, as shown in fig. 7, two limit mechanisms are symmetrically provided, i.e., between the intermediate pedal 3 and the first pedal 1 and between the intermediate pedal 3 and the second pedal 2, respectively, and the longitudinal directions of the two limit grooves 10 of the two limit mechanisms are aligned in the traveling direction of the vehicle, which structure is more advantageous in the adaptive centering of the pedal assembly, realizes stable movements of the pedals, and reduces deformation of each pedal.

According to one example, a support seat 7 is also provided for the pedal assembly. In the example of fig. 7, four support seats 7 are included, which are symmetrically arranged to be supported on the first pedal 1 and the second pedal 2, respectively. Each support seat 7 is fixed to the corresponding compartment and extends below the corresponding pedal to support the pedal. The first pedal 1 and the second pedal 2 are installed on the floor surface of the corresponding vehicle body end wall on one side, and the other side is put on the supporting seat 7. The arrangement of the support seat 7 improves the structural strength and the support performance of the pedal assembly, and the stable movement.

As can be seen in connection with fig. 6 and 7, the support seat 7 is preferably constructed as a sheet metal part of overall U-shaped cross section and is fixed to the respective car at the closed end of the U-shape, and the two legs 71 of the U-shape extend under the respective pedal to support the latter. The support seat with the structure and the installation mode has higher strength, is more beneficial to supporting the first pedal 1/the second pedal 2, saves materials and reduces the weight of the pedal assembly.

As described above, the pedal assembly employing the exemplary structures of the present utility model has more stable and reliable movement and can reduce the twisting deformation of each pedal, can meet the movement stability required for small radius curve conditions of vehicles, particularly monorail vehicles, and can improve the life of the pedal assembly. Accordingly, the present utility model provides a through passage including the above pedal assembly, which thus has various advantages possessed by the pedal assembly.

As an example, as shown in fig. 1, the through-channel of the present utility model further includes a bellows assembly. The bellows assembly includes a main bellows 81 and two bottom bellows 82 connected to both sides of the lower portion of the main bellows 81, respectively. As shown in fig. 2 to 4, at least one bottom shed 82 includes a plurality of clamping profiles 821 clamping a shed cloth, a plurality of guide blocks 822 respectively connected to lower ends of the plurality of clamping profiles 821 correspondingly, and a rod 823 (also referred to as a stabilizer rod) through which the plurality of guide blocks 822 are provided and capable of sliding with respect thereto. In the particular example shown in the figures, the bottom shelf 82 further comprises a mount 824 secured to the body end wall of one compartment and a ball pivot seat 825 attached thereto, for example by screws, wherein a rod 823 is attached in the ball pivot seat 825, the end of the rod 823 remote from the ball pivot seat 825 being located in a hole provided in the other compartment. The stabilizer bar is thus positioned at one end in the ball-and-socket 825 and at one end through each guide block 822 and then into the hole reserved in the body end wall of the other car. When the vehicle runs, the part of the stabilizer bar penetrating into the vehicle body end wall can slide in the hole, and the end part of the rod 823 is ensured not to move out of the hole of the vehicle body end wall by setting the depth of the hole and reserving the rod with a certain length in the hole.

Because the through channel adopts the structure of the bottom shed 82, the tail end of the clamping section bar 821 of the bottom shed is sleeved on the rod 823 with the stabilizing function through the guide block 822, so that the deformation or shaking of the end part of the bottom shed 82 can be prevented when a vehicle passes through a curve, and the vehicle shakes or has the action of air pressure difference, and the stability and the reliability of the bottom shed and the whole folding shed assembly are ensured. Moreover, the use of U-shaped connecting profiles for connecting the fixed clamping profiles takes up less space than the way in which they are used in the prior art, and can be applied in particular to monorail vehicles using jacob bogies, for example.

The utility model also relates to a vehicle comprising at least two carriages, the vehicle comprising a through channel as described above arranged between two adjacent carriages. The vehicle is in particular a monorail vehicle and/or a jacob bogie vehicle. The vehicle of the present utility model thus has various advantages associated with the pedal assembly and the through passage having the above-described structure.
