Device for testing horizontal rigidity performance of motorcycle frame

Abstract

The invention discloses a device for testing the horizontal rigidity performance of a motorcycle frame. The device comprises a base, wherein one end of the base is provided with a horizontal support, the horizontal support is provided with a pressure cylinder by virtue of an oil cylinder support, the tail end of a piston rod of the pressure cylinder is connected with a horizontal sliding seat, the horizontal sliding seat is arranged on a sliding rail on the horizontal support by virtue of a sliding block, the upper surface of the horizontal sliding seat is provided with a head stock rod support, the head stock rod support is connected with a head stock rod shaft used for fixing a front fork of the motorcycle frame by virtue of a front wheel rotating shaft; one side of the horizontal sliding seat along the direction of the sliding rail is provided with a grating bar sliding plate, and a grating bar corresponding to the grating bar sliding plate is fixed on the horizontal support; and the middle part of the base is provided with a left support seat and a right support seat which are used for fixing a rear fork of the motorcycle frame. By applying the device disclosed by the invention, the actual road frame horizontal rigidity performance test carried out before new products are put into production in the prior art is abandoned, and requirements for testing and evaluating the strength and rigidity performances in the horizontal direction of the frame in a development process of the motorcycle frame are met.

Description

technical field [0001] The invention relates to a performance testing device, in particular to a motorcycle frame horizontal stiffness performance testing device for testing the horizontal strength or stiffness of a developed new motorcycle frame to ensure sufficient safety. Background technique [0002] The motorcycle frame is the core component of the motorcycle and plays a supporting role in the whole motorcycle. It connects the engine, transmission components, control components, etc. together to form a whole. The motorcycle frame carries the load of the whole vehicle and is the most important part of the vehicle; in addition, the motorcycle will be impacted by the road during driving, such as figure 1 As shown, when the front wheel is excited by the impact when encountering an upper step or a boss, the impact force F on the front wheel can be decomposed into a horizontal component force Fh and a vertical component force Fv, and the vertical component force Fv is mostly...

Problems solved by technology

However, there is currently a lack of a device that can effectively test and analyze the horizontal stiffness of the newly developed motorcycle frame. Generally, new products are currently tested on roads of 6,000-10,000 kilometers before they are put into production. According to the regulations of related industries Requirements, this test needs to be tested on a certain proportion of road types, which not only takes at least three months, but also requires a lot of financial and material resources; in addition, collecting field data is a challenging task, and its difficulty lies in the fact that each section The time and working conditions are difficult to be consistent and time-consuming. When recording the whole process of product usage in detail, it is necessary to have corresponding management personnel to organize and manage, so as to obtain more accurate data.

The traditional road test method is time-consuming, costly and labor-intensive, and it is not conducive to the rapid introduction of new products into the market
