Abstract

The invention discloses a chassis structure of a low-floor rail vehicle. The chassis structure comprises end beams arranged at the two ends respectively. An aisle floor is fixed between the end beams at the two ends. Side portion assemblies are arranged on the two sides of the aisle floor and are fixedly connected with the end beams. The side portion assemblies comprise transverse seat installation plates and longitudinal seat installation plates, wherein the longitudinal seat installation plates are higher than the transverse seat installation plates, and the transverse seat installation plates and the longitudinal seat installation plates form an inverted-T-shaped structure. The aisle floor is flush with other floors of a vehicle body. A traction seat is arranged at the back face of the part, located at the longitudinal seat installation plates, of the aisle floor. Transverse stopping blocks are arranged on the two sides of the traction seat, and perpendicular stopping blocks perpendicular to the transverse stopping blocks are arranged . Hollow perpendicular shock absorber installation seats are arranged on the front faces of the longitudinal seat installation plates in a protruding manner. According to the chassis structure of the low-floor rail vehicle, the non-step and slope-aisle structural design is adopted, the floor height does not need to be increased, and the low floors are ensured absolutely. Seats are longitudinally and transversely distributed, space arrangement is reasonable, and vehicle stability is good.

Description

A kind of low-floor rail vehicle Undercarriage structure
Technical field
The invention belongs to rail vehicle body technique, be specifically related to a kind of low-floor rail vehicle underframe connection structure.
Background technology
Domestic and international low floor tramway train is realize the connection with bogie truck, above bogie truck, passageway is generally designed with step or inclined-plane, has raised floor level at middle part, to meet car body strength and rigidity requirement, not only decrease inner space, travelling comfort and the visual field are all undesirable.
The low floor car body of prior art, seat employing is horizontally-arranged to be arranged in opposite directions, and take space little, extremity may also occur, therefore tramway train insufficient space is maximum drawback.

Described traction seat both sides, be connected with box traction seat laterally strengthen structure with vertical backstop, this traction seat is laterally strengthened structure and is extended to longitudinal chair mounted back edge.Can by the power lateral transport of traction seat to side wall.
Preferably, described traction seat laterally strengthen structure and vertical backstop one-body molded.
Further, described longitudinal chair mounted back, be positioned at traction seat and laterally strengthen structure both sides and be provided with sky spring mount pad.Because longitudinal chair mounted plate is protruding, the attachment face of the spring mount pad that makes to have leisure is higher, can increase bogie truck and car body vertical distance, adequate space can be had to arrange other equipment.And empty spring attachment face is near car body two side ends, after empty spring is installed, the distance between empty spring and empty spring is comparatively large, vehicle operating good stability.
Preferably, described horizontal backstop and vertical backstop intersection are provided with box-like reinforcement structure.Can by the power lateral transport of traction seat to side wall, and provide intensity for horizontal stop and vertical stop.
Described every butt beam two ends are provided with warping resistance system mount pad, and this warping resistance system mount pad comprises reinforced rib, adapter plate, cover plate, and warping resistance system mount pad is fixedly connected with end carriage, forms totally-enclosed box like structure.This structure can ensure installing space and the requirement of strength of warping resistance system.
The described cross seat adapter plate back side is provided with seat strength beam.To increase the strength and stiffness at chair mounted place.
Stretcher is provided with below described longitudinal chair mounted plate.Highly moderate, and meet ergonomics, make full use of space, effectively solve the less shortcoming in low floor vehicle space.
Remarkable result of the present invention is:
1. Undercarriage structure adopts without step and passageway, inclined-plane structure design, without the need to raising floor level; Seat distribution adopts vertical, horizontal distribution, effectively utilizes space, meets ergonomics, ride comfort and can not contacting with each other.
2. vertical bumper mount pad can not only provide the installation of vertical bumper, also has bogie truck crane function, without the need to newly-increased crane structure.
3. sidepiece assembling not only provides sky spring to install below, also provides longitudinal seat above.And empty spring attachment face is higher, bogie truck and car body vertical distance can be increased, have adequate space to arrange other equipment.Empty spring attachment face is near car body two side ends, and the pivot distance of formation is comparatively large, vehicle operating good stability.
4. laterally reinforcement structural integrity is shaping for vertical stop and traction seat, not only plays the effect laterally strengthened, also plays the effect of vertical stop.
5. end carriage carries warping resistance system installation structure, Appropriate application space.
