Support mechanism for middle section of chassis of passenger vehicle

Abstract

The invention discloses a support mechanism for a middle section of chassis of a passenger vehicle. The support mechanism comprises a first rectangular frame and a second rectangular frame. The first rectangular frame and the second rectangular frame are parallel to each other, two transverse beams are welded between two sides of the upper end of the first rectangular frame and two sides of the upper end of the second rectangular frame, and floor beams which are uniformly distributed are welded between the lower end of the first rectangular frame and the lower end of the second rectangular frame; triangular frames are perpendicularly fixed onto first support rods, and two threading pipes which are connected with each other are fixed to the upper end of each triangular frame; bosses are arranged at the upper end and the lower end of each second support rod, and slide grooves which are matched with the bosses are formed in the upper end and the lower end of the second rectangular frame. The support mechanism has the advantages that the support mechanism is used for supporting the middle section of the chassis of the passenger vehicle, can be firmly fixed and is difficult to deform; shaking generated by the passenger vehicle in driving procedures can be reduced, and accordingly the support mechanism is quite practical and has popularization value; the triangular frames and the threading pipes are arranged on the first support rods, and accordingly wires can be arranged at the bottom of the passenger vehicle; the second support rods are slidably assembled on the second rectangular frame, and accordingly large luggage of passengers can be stored.

Description

technical field [0001] The invention belongs to the technical field of passenger cars, in particular to a support mechanism for the middle section of the underframe of a passenger car. Background technique [0002] The bus chassis is a rectangular frame composed of various longitudinal and transverse steel beams. It supports the car body and is the foundation of the car body. The underframe of the passenger car bears the entire weight of the upper car body and the load, and transmits the weight to the running part through the upper and lower center plates. When the train is running, it also bears the traction of the locomotive And various impacts and other external forces caused by the operation of the train, so it must have sufficient strength and rigidity to be durable. [0003] The middle section of the passenger car underframe currently used is generally welded or riveted with thick plate channel-shaped longitudinal beams and channel-shaped inner and outer beams to form...

Problems solved by technology

[0004] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a support mechanism for the middle section of the underframe of a passenger car. By designing a tripod and a threading pipe on the first support rod, the problem of wiring at the bottom of the passenger car is solved. The upper sliding assembly of the second support rod solves the problem of storing large luggage for passengers
