Problems solved by technology

[0003] Automatic transmissions involve multidisciplinary fields such as mechanics, hydraulics, electronics, and control. Their working conditions are very complex and have extremely high safety requirements, which brings the complexity of transmission design. For complex multi-gear , Multi-logic automatic transmission, because it is difficult to simulate in the actual environment, the defects in the conceptual design and modeling cannot be found in time, and for safety reasons, it cannot be gradually improved in use, and can only rely on road tests Come to find out that it takes time and effort, increases the development cost, and lengthens the development cycle. The emergence of automatic transmission simulation can solve this problem, reduce costs, and shorten the development cycle.

Abstract

The invention provides a gearbox simulation test system which comprises a work table, a main engine, a drive motor, a gearbox, a gearbox controller, a connection mechanism, a support, a measuring part and a stopper. The main engine is arranged in the non-action area of the work table. The drive motor is fixed on one end of the work table. The drive motor is connected with the gearbox through the connection mechanism. The gearbox is fixedly connected with the work table through the support. The main engine calculates the actual transmission ratio according to the rotational speed of the drive motor and the output rotational speed of the gearbox in a simulation condition, and outputs the actual transmission ratio to a display device. An automatic gearbox model is provided with engine torque input close to a real vehicle, so as to constitute a virtual vehicle gearbox controller development simulation platform close to the real vehicle. The development and test efficiency of the gearbox controller can be greatly improved. The development cycle is shortened. The development cost and risk are reduced.

Description

Technical field [0001] The invention provides a device for simulating a gearbox transmission system of a vehicle. Background technique [0002] Since cars with automatic gearboxes can automatically shift and change torque according to the driver's control of the throttle, they run smoothly and are easy to operate, which not only brings convenience to drivers, but also brings comfort to passengers, and has become popular in civilian vehicles. With the development of the automotive industry, the application of automatic transmissions will increase. [0003] Automatic gearboxes involve multi-disciplinary fields such as machinery, hydraulics, electronics, and control. Their working conditions are very complex and require high safety requirements. This brings complexity to the gearbox design. For more complex multi-gear , Multi-logic automatic transmission, because it is difficult to simulate in the actual environment, the defects in conceptual design and modeling cannot be found in ti...
