Problems solved by technology

Hydraulic drive and motor drive have fast response speed and accurate positioning, but the cushioning effect is poor and the shifting impact is large; pneumatic drive has good cushioning performance and can best simulate the shifting effect of a human hand, but the positioning accuracy is poor
The current solution is to add a mechanical positioning device to the cylinder, which can improve the positioning accuracy, but it will inevitably produce shocks, and the shifting speed and shifting force will pulsate, and the position of the positioning device needs to be changed when the shifting stroke changes. , complex operation, heavy workload
[0004] The domestic mainstream test bench control system mostly adopts the joint control of industrial computer and data acquisition card, which not only requires high stability of industrial computer, but also requires an industrial computer to control each test bench, resulting in high development costs and resource constraints. Great waste

Abstract

The invention discloses a gear shifting manipulator of an automobile synchronizer testbed and a control device of the gear shifting manipulator. The gear shifting manipulator comprises a mounting bottom plate and a four-bar mechanism which is formed by hinge joint of a gear selecting shaft, a gear shifting rocker arm, a middle connecting bar and a gear shifting support bar, the gear selecting shaft is rotatably mounted on the mounting plate, an output shaft of a gear selecting motor is in transmission connection with the gear selecting shaft, a gear shifting air cylinder is hinged between the gear selecting shaft and the gear shifting rocker arm, a gear shifting connection bar is hinged to the upper end of the gear shifting support bar, and a tensile pressure sensor and angle sensors are arranged on the four-bar mechanism respectively. The control device comprises an MCU (micro control unit) and a human-computer interface LCD (liquid crystal display). The gear shifting manipulator is electrically connected with the MCU via the tensile pressure sensor and the angle sensors. The MCU is electrically connected with a gear shafting electromagnetic valve of the gear shifting air cylinder and the gear shifting motor. The human-computer interface LCD is in communication connection with the MCU. The gear shifting manipulator of the automobile synchronizer testbed and the control device of the gear shifting manipulator have the advantages of simplicity in operation, high positioning precision, precise controllability, stability in operation and capability of simulating a gear shifting effect of a human hand better.

Description

technical field [0001] The invention belongs to the technical field of automobile test devices, and in particular relates to an automobile synchronizer test bench shift manipulator and a control device thereof, which are used for performance tests and life tests of automobile gearbox synchronizers. Background technique [0002] The performance and life test of automobile synchronizer is an important part of the bench test of automobile mechanical manual transmission, so the automobile manufacturer lists this test as an important link in the product development process. Foreign countries started the research and development of synchronizer performance and life test benches earlier, and developed a variety of test bench products with different structures and performances. In China, many universities and research institutes have developed a variety of synchronizer test benches with different performances, but they generally have the disadvantages of single function, high cost, ...
