Simulation load assembly capable of improving testing precision and applied to automobile cable testing machine

Abstract

The invention relates to a simulation load assembly capable of improving testing precision and applied to an automobile cable testing machine. The simulation load assembly includes a gearbox transmission simulator, a controller, a load driver used for providing a power source for the load end of an automobile cable, and a force sensor connected between the gearbox transmission simulator and the load driver; the load end of the automobile cable passes through the gearbox transmission simulator and is connected with the force sensor; the force sensor is fixed to a connection seat; the load driver includes pull ropes, weights and a guide seat; the guide seat is provided with guide wheels; the guide wheels support the middle parts of the pull ropes in the length direction; one end of each pull rope is connected with the connecting seat; and the weights are suspended on the other ends of the pull ropes. With the simulation load assembly of the invention adopted, the actuation environment of the load end of the cable in the actual actuation of an automobile can be simulated. The simulation load assembly can be used in cooperation with the driving end of the testing machine so as to test the friction and strength of the automobile cable and completely simulate displacement and force transmission efficiency of the automobile cable in the actuation environment of the automobile. With the simulation load assembly adopted, test results are very accurate and stable.

Description

technical field [0001] The invention belongs to the technical field of auto parts testing tooling, and in particular relates to a simulated load assembly for an automotive cable testing machine with improved testing accuracy. Background technique [0002] As automobiles began to enter individual families, the domestic demand for automobiles is growing rapidly every year, and the automobile industry has become an important pillar industry. In this case, the production and manufacturing of automobile parts has also entered an era of rapid development. The car cable is an important part of the car, which can control the actuator of the car from a long distance. The car cables include shift cables, clutch cables, accelerator cables, door cables, brake cables, etc. When testing technical parameters such as tension, friction and load efficiency of the cable, the automotive cable testing machine needs to completely simulate the action environment during the operation of the car. Th...

Problems solved by technology

The simulated load assembly of the current automobile cable inspection machine is difficult to achieve multi-technical index testing; and due to the unreasonable structural design of the load driver, the force value provided by it is unstable and the force value is not accurate enough, which ultimately affects various technologies. The accuracy and stability of the index test, the error is large, and the measurement limitations are large. Many of the above defects need to be improved
