Motorcycle frame

Abstract

The invention discloses a motorcycle frame, which comprises a front body assembly, a middle body assembly, a rear body assembly and an engine suspension assembly which are connected by bolts. The motorcycle frame is conveniently and flexibly disassembled, reduces the occupation space of the frame before assembling the motorcycle and package and transportation costs, improves utilization rate of astoreroom, has good universality and interchangeability and only needs to exchange the part if the welding position and size of parts in the part are not accurate or the parts are partially damaged. The motorcycle frame also facilitates the assembly of an engine, thereby greatly reducing the disassembly difficulty of the engine and the labor intensity of workers and effectively improving the assembly efficiency.

Description

technical field [0001] The invention relates to a motorcycle frame, in particular to a cradle type split frame of the motorcycle. Background technique [0002] At present, the motorcycle cradle frame is an integral structure formed by welding, which has the advantage of good rigidity and high strength of the frame. However, the integral frame takes up a large space before loading, which will not only increase the packaging and transportation costs, but also reduce the utilization rate of the warehouse. At the same time, if the welding position and size of a certain part on the vehicle frame are inaccurate, or if local damage occurs during transportation, the entire vehicle frame will be scrapped because it cannot be used, resulting in great waste. In addition, there is an engine installation space in the lower part of the frame, which is slightly larger than the engine. When installing the engine, the engine must be installed in the installation space first, and then the li...

AI Technical Summary

Problems solved by technology

However, the integral frame takes up a lot of space before loading, which will not only increase the cost of packaging and transportation, but also reduce the utilization rate of the warehouse

At the same time, if the welding position and size of a certain part on the frame are inaccurate, or if there is partial damage during transportation, the entire frame will be scrapped because it cannot be used, resulting in great waste

In addition, there is an engine installation space in the lower part of the frame, which is slightly larger than the engine. When installing the engine, the engine must be installed in the installation space first, and then the lifting lug at the front end of the engine is connected to the connecting pipe on the lower body through bolts. The engine front lugs are connected, and the engine rear lugs are connected to the engine rear lugs on the connecting plate on the engine through bolts. Due to the limited operating space, it is very troublesome to install the engine and fasten it, and the labor intensity of the workers is extremely high. , and the assembly efficiency is low; similarly, when the engine fails and needs to be removed from the frame for repair, there are also problems such as complicated operation, time-consuming and laborious
