Manual transmission automatic gear shifting device and gear shifting method

Abstract

The invention belongs to the field of vehicle equipment parts, mainly provides an automatic gear shifting and choosing device of manual transmission, and is used for achieving gear shifting and choosing motions of the manual transmission. The automatic gear shifting and choosing device of the manual transmission comprises a gear shifting mechanism, a gear choosing mechanism, an air valve set and an electric control mechanism. The automatic gear shifting and choosing device of the manual transmission adopts a structure formed by connecting a plurality of cylinders which are adjustable in locations in series, the structure is simple, running is reliable, the cost is low, the operation and maintenance are convenient, and related technical requirements on a user are not high. In addition, The automatic gear shifting and choosing device of the manual transmission is adjustable in gear shifting location, the installing requirements are not high, the automatic gear shifting and choosing device can be suitable for transmission with different gear shifting and choosing routes, the flexibility is high, furthermore, controlling of flexible gear shifting sequences and gear shifting times can be achieved, and the automatic gear shifting and choosing device is suitable for being used in a laboratory or batch production environment.

Description

technical field [0001] The invention belongs to the field of vehicle equipment parts, and more specifically, the invention relates to a device and method for automatically shifting gears of a manual transmission. Background technique [0002] In the process of R&D or mass production of manual transmissions, it is usually necessary to use automatic shifting devices for manual transmissions to achieve figure 1 Select the shift position shown in order to achieve the purpose of life test (development life test) or function test (development or mass production) of the shifting mechanism. For this, there are currently three main methods: [0003] 1. Directly operate the manual transmission shift lever to perform manual shifting operations. This method is only suitable for functional testing purposes with a small number of times, and the labor intensity of manual operations is high; [0004] 2. Through a gearshift control mechanism (shift lever) similar to a vehicle-mounted transm...

Problems solved by technology

[0006] Among the above three methods, the first method cannot be automated, so it is not suitable for fatigue life tests (such as shift life tests) with repetitions of tens or even millions of times, or end-of-line functional tests for mass production The automatic shifting of gears; the second method is only partially automated (manual gear selection, automatic gear shifting), so it is mainly used in the shift life test of manual gear selection; the third method is through a two-axis servo device, It has good flexibility and is easy to realize automation, but the cost is high, and in the process such as the transmission life test, if the type needs to be changed, high parameter adjustment skills (such as servo parameter setting, etc.) are required, so it cannot be achieved. good promotion and utilization
