Eccentric primary suspension and rotating arm locating structure of suspension type monorail vehicle bogie

Abstract

The invention discloses an eccentric primary suspension and rotating arm locating structure of a suspension type monorail vehicle bogie. The structure comprises a gear case body. The gear case body isprovided with an axle. A rotating arm and a primary rubber spring are arranged in the positions, located on the two sides of the axle, of the gear case body. The rotating arm is connected through a rotating arm hole in a lug on the gear case body. The primary rubber spring is connected through a spring installation seat on the gear case body. The primary rubber spring and the rotating arm are symmetrically arranged at the two ends of a gear case, so that the primary rubber spring deviates from the center line of the axle, the primary rubber spring and the rotating arm jointly bear a verticalload, an eccentric primary suspension is formed, two rubber shaft sleeves are symmetrically arranged on the left side and the right side of the gear case body, longitudinal and transverse elastic connection with a framework is achieved, the problem that an independent axle case body cannot be arranged on a suspension type monorail vehicle, so that the primary suspension is difficult to design is solved, the requirement of the bogie for the large primary deflection can be met as well, and the contradiction between the limited space size and the required large primary deflection is overcome.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to an eccentric primary suspension and a pivot arm positioning structure of a suspended monorail vehicle bogie. Background technique [0002] The axle box and the primary suspension device are very important parts of the bogie. The ground rail transit often has a series of suspension device between the wheel set and the frame, and the axle box spring can alleviate the impact caused by the uneven track to improve ride comfort. , but due to the limited space of suspended monorail vehicles, it is difficult to design a series of suspensions with reference to traditional ground rail transit. [0003] The primary suspension device of traditional ground rail transit is realized by elastically connecting the wheel set and the bogie through axle boxes, axle box springs and other components. In the suspended monorail vehicle bogie, it is difficult to symmetrically arrange two inde...

Problems solved by technology

[0006] The purpose of the present invention is to overcome the above-mentioned problems that exist in the prior art, propose the eccentric type primary suspension of suspension type monorail vehicle bogie and the pivoting arm positioning structure, a series of rubber springs and pivoting arms are symmetrically arranged at the two ends of the gear box, so that The first series of rubber springs deviate from the center line of the axle, and share the vertical load with the rotating arm to form an eccentric primary suspension, and two rubber bushes are symmetrically arranged on the left and right sides of the gearbox case to achieve vertical and horizontal alignment with the frame. The elastic connection solves the problem that the suspended monorail vehicle cannot be equipped with an independent axle box, which leads to the difficult design of the primary suspension. It can also meet the needs of the bogie for large deflection of the primary system, and can adapt to the tension of the suspended monorail vehicle bogie. The vertical installation space solves the contradiction between the limited space size and the need for a large series of deflection
