Frame of a three-wheeled motorcycle

Abstract

The invention discloses a frame of a right three-wheeled motorcycle. The frame comprises a cab bottom beam frame, a container supporting beam frame, two lengthened beams and a rear tail beam, wherein the container supporting beam frame is provided with two parallel longitudinal beams and fixedly connected with the cab bottom beam frame. Connecting end plates are arranged at the rear ends of the two longitudinal beams, and a plurality of mounting holes are arranged on the connecting end plates and used for mounting and connecting the lengthened beams or the rear tail beam. Connecting end plates are arranged at the front ends and the rear ends of the lengthened beams respectively, a plurality of mounting holes are arranged on the connecting end plates, a plurality of mounting holes are arranged at the left end and the right end of the rear tail beam respectively, and the mounting holes on the connecting end plates at the rear ends of the longitudinal beams, the mounting holes on the connecting end plates of the lengthened beams and the mounting holes on the rear tail beam mutually correspond. The frame is of a detachable assembly structure and higher in anti-collision strength, production cost is reduced, various signals and lighting devices and a rear bumper are arranged on the rear tail beam, and the manufacturing cost of the right three-wheeled motorcycle is reduced.

Description

technical field [0001] The invention relates to the field of three-wheeled motorcycles, in particular to a frame of a three-wheeled motorcycle. Background technique [0002] The frame of the traditional three-wheeled motorcycle is an integral welded and fixed structure. The longitudinal beams, beams and tail beams of the three-wheeled motorcycle frame are fixed together and cannot be disassembled or assembled. However, the three-wheeled motorcycle Many vehicles are used as agricultural vehicles, and the types of goods reproduced are more complicated, so the requirements for the volume of the cargo boxes are inconsistent. The three-wheeled motorcycle frame with traditional rectangular profile assembly and welding structure needs to be assembled and welded with different shapes and specifications to match the container according to the volume and load of the container during production and assembly. The frame is produced on different production lines, which will greatly incre...

AI Technical Summary

Problems solved by technology

The cargo box needs to meet the needs of loading and add mounting seats for various signals and lighting appliances, which makes the structure of the cargo box very complicated. When producing and assembling the cargo box, a large number of fixtures need to be invested, and the assembly line needs to be replaced frequently Fixtures, production and assembly auxiliary time is long, production efficiency is low, and manufacturing cost is high

Moreover, the rear of the cargo box is provided with mounting seats for signals and lighting appliances, which occupies the best position for installing the bumper, making the anti-collision strength of the three-wheeled motorcycle not good.
