Embodiment 1

[0039] Embodiment 1: as Figure 1 to Figure 3 As shown, an elastic hinge device for low-floor vehicles with adjustable stiffness includes a center pin 1, a ball joint pair 2 and a rigid hook 3 fixedly arranged on a carriage. The center pin 1 and the rigid hook 3 Fixedly connected as a whole, the elastic hinge device of the low-floor vehicle also includes a middle plate 4, a front support 5 and a rear support 6 respectively arranged on opposite sides of the middle plate 4, the front support 5, the rear support 6 and the middle plate 4 are integrally connected by M16 bolts, and the rubber support body 1 7 and the rubber support body 2 8 that support the middle plate 4 in the air by connecting with the opposite sides of the middle plate 4 are arranged on the The rubber stop one 9 and the rubber stop two 10 on the opposite sides of the rear support 6 cooperate with the rubber stop one 9 and the rubber stop two 10 and are respectively fixedly arranged on the rubber support body one...

Embodiment 2

[0050] Embodiment 2: as Figure 10 to Figure 12 As shown, compared with Embodiment 1, the difference is: the front elastic rubber body 133 of the rubber support body one 7, the rear elastic rubber body 143 of the rubber support body one 7, and the front elastic rubber body 143 of the rubber support body two 8 The rear elastic rubber body 143 of the body 133 and the rubber support body 2 8 is all in a longitudinally pre-compressed state. The front and rear elastic rubber bodies of rubber support body 1 7 and rubber support body 2 8 are pre-compressed to a certain amount during assembly, so that the device only bears compressive stress during the operation of the train, which satisfies the The use requirements greatly improve the service life of the front and rear elastic rubber bodies. The front elastic rubber body and the rear elastic rubber body are individually pre-compressed during assemblyL 3 , assuming that the longitudinal stiffness of the front elastic rubber body and...

Abstract

The invention discloses a rigidity-adjustable elastic hinging device of a low-floor train and a rigidity adjusting method of the rigidity-adjustable elastic hinging device. The elastic hinging device of the low-floor train comprises a center pin, a spherical hinge joint pair and a rigid hook. The center pin is integrally connected with the rigid hook. The elastic hinging device further comprises a middle plate, a front support, a rear support, a first rubber supporting body, a second rubber supporting body, a first rubber backstop, a second rubber backstop, a first transverse stop block and a second transverse stop block. The front support and the rear support are both arranged between the first rubber supporting body and the second rubber supporting body. Rubber in the first rubber supporting body and rubber in the second rubber supporting body are both transverse and pre-stretched in the direction away from the front support and the rear support. The spherical hinge joint pair and the front support are integrally connected. The inner diameter of the spherical hinge joint pair is matched with the outer diameter of the center pin. The center pin penetrates through the spherical hinge joint pair, so that the rigid hook and the front support are connected in a matched mode. By means of the rigidity-adjustable elastic hinging device, the requirement for a small-curvature radius of an urban track is met while the train operation comfort is improved, and the driving safety can be guaranteed.

Description

technical field [0001] The invention relates to a hinged part of a low-floor light rail vehicle and a working method thereof, in particular to an elastic hinged device of a low-floor vehicle with adjustable stiffness and a method for adjusting the stiffness thereof, belonging to the technical field of rail transit trains. Background technique [0002] At present, with the increase of urban passenger flow, it is an inevitable trend for low-floor light rail trains to be flexible in multiple joints and marshalling types. However, the floor surface of low-floor light rail trains is relatively close to the rail surface, and there is no traditional coupler installation space. , and the rail transit routes in the city have the characteristics of small curvature radius and steep ramps, a suitable low-floor rail train coupling mechanism is urgently needed to meet the above requirements. [0003] In existing low-floor trains, fixed hinge devices are generally used between the bottoms ...
