Manual transmission gear-shifting control device

Abstract

The invention relates to the evaluation of manual transmissions, and provides a manual transmission gear-shifting control device which aims to achieve the control over tests of avoiding the operation of gear selection and simplifying in-gear operation and off-gear operation when the gear shifting characteristics of transmissions in the gear shifting process are evaluated. The manual transmission gear-shifting control device comprises a gear-shifting actuator, a hydraulic station and a motion control unit. The gear-shifting actuator comprises a hydraulic cylinder, a piston rod, a traction bar, a swing rod, a gear-shifting shaft and a shifting fork. The hydraulic station comprises an oil tank, a motor, a pump, a safety overflow valve, a proportional pressure valve, a solenoid directional valve, a lockup valve, a throttling valve, an air cooler and an oil filter. The motion control unit comprises a motion control card, travel switches, a rotating speed sensor and a relay. The manual transmission gear-shifting control device can adjust the gear-shifting force when gears are shifted, the gear-shifting force and the gear-shifting displacement of the transmission are collected, and the circulation gear-shifting of the transmission is achieved by controlling an oil way of the solenoid directional valve. The manual transmission gear-shifting control device for the tests has multiple gear-shifting modes, and is convenient to demount and mount, and capable of being widely used for the circulation gear-shifting control over manual transmissions of different types.

Description

technical field [0001] The invention belongs to the technical field of vehicle engineering transmission, and relates to a vehicle gearbox, in particular to gear shift control for evaluating a manual gearbox. Background technique [0002] Piston-type internal combustion engines are widely used as power sources in modern automobiles, and the variation range of its torque and rotational speed is relatively small, but the complex conditions of use require that the driving force and speed of the automobile can be varied within a considerable range. In order to solve this contradiction, a gearbox is provided in the transmission system. It can be seen that the gearbox is an important part of the vehicle transmission system, and its performance directly affects the performance of the transmission system. In order to evaluate the structure of the gearbox and the performance of its components to guide product design and shorten the development cycle, building a gearbox shift control ...
