Embodiment Construction

[0030] A versatile compact center pin puller such as figure 2 As shown, the traction device is mainly composed of a center pin seat 1, a traction seat 2, a lifting pin 3, a lifting wire rope 4, a draw bar assembly 5, a transverse shock absorber 6, and a transverse stopper 7.

[0031] Such as Figure 4 As shown, the central pin seat 1 is a hollow monolithic structure with a central rotary hole 16, the upper end is connected with the vehicle body through bolts, and the lower end is connected with the traction seat through a traction rubber tube, which plays the role of transmitting traction and braking force, and can To accommodate the rotation of the car body relative to the bogie. There are two lateral shock absorber mounts on the center pin seat to absorb lateral vibration. The center rotation hole 16 is surrounded by an annular boss that extends upward for at least 10mm, and the annular boss cooperates with the end of the vehicle body to form a notch structure.

Abstract

The invention discloses a multifunctional compact traction device for a center pin. The traction device comprises a center pin seat, a traction base connected with the center pin seat, a traction bar assembly installed on the traction base and transverse absorbers, wherein the lower parts of the center pin seat are provided with two absorber seats as rib plates, the absorber seats are provided with transverse absorbers; the traction seat is a semi-closed structure used for enveloping the traction bar, and the left side plate and right side plate of the traction seat are provided with transverse backstops. According to the multifunctional compact traction device provided by the invention, the structure can be simplified and the functions of the traction devices can be enriched; furthermore, the problems that the traction seat is large in welding quantity, the center pin seat is single in function and the interference is likely to be caused can be solved to a large extent.

Description

technical field [0001] The invention relates to a rail transit vehicle bogie traction device, in particular to a multifunctional and compact central pin traction device. Background technique [0002] As a longitudinal connecting device, the traction device is widely used in various types of railway freight cars and passenger cars at home and abroad. The traction device mainly connects the car body and frame, transmits traction and braking force, and adapts to the rotation of the car body relative to the bogie. [0003] Chinese patent CN201020135665.0 discloses a traction device with a compact central pin seat and a Z-shaped pull rod structure, such as figure 1 As shown, the structure is mainly composed of a center pin seat assembly 1, a transverse damper seat 8, a traction seat assembly 2, a drawbar assembly 5, a transverse stopper 7, and a transverse shock absorber 6. This kind of traction device has a compact structure and saves installation space, but this kind of tracti...
