Dual control pneumatic assisted shift handle with air inlet and outlet structure

Abstract

The invention provides a double-control pneumatic auxiliary gear shift handle with an air inlet and outlet structure. The double-control pneumatic auxiliary gear shift handle comprises a housing, a valve body, a front working hole valve core combination, a front control button, a side working hole valve core combination, a side control button, the air inlet and outlet structure and a double-control air channel structure, wherein the air inlet and outlet structure comprises an air pipe combination in an air inlet structure, two air pipe combinations for a working air channel in an air outlet structure and an air pipe combination for an exhaust air channel in the air outlet structure; each air pipe combination comprises a connector body and an air pipe; the connector body is connected with the double-control air channel structure; each the air pipe combination in the air inlet structure and the air pipe combinations for the working air channel in the air outlet structure comprises a quick connector; and the quick connector is connected with a quick insertion connector outside the bottom of the valve body. The invention provides an auxiliary gear shift device which is simple and compact in structure and easy to operate, so that the auxiliary gear shift handle is better in sealing performance and longer in service life.

Description

technical field [0001] The invention relates to an auxiliary shifting device, in particular to a dual-control pneumatic auxiliary shifting handle device with an air inlet and outlet structure for a vehicle. Background technique [0002] After surviving the cold winter of the global financial tsunami crisis in 2009, the European and American markets have entered a period of declining demand, and the scale of the Chinese auto market has entered a period of rapid and rapid development, with production and sales ranking first in the world and heavy truck production and sales expanding rapidly. According to the latest data, the number of heavy trucks exceeded 1 million in 2010. Although my country's economy has been greatly impacted by the financial crisis, with the implementation of the country's 4 trillion yuan expansion of domestic demand policy and the development of markets in overseas developing countries, along with the successive start of my country's roads, railways and ...

Problems solved by technology

The prior art auxiliary gear shifting device uses a slide plate design, which has a large operating resistance and is not easy to shift gears, and frequent sliding friction is likely to cause loss of parts such as sealing rings, resulting in defects such as easy air leakage and high failure rate, which reduces the service life. Moreover, the design directly discharges excess gas into the driver's cab through the exhaust hole provided on the shift handle, which is likely to cause noise and pollution to the driver's cab, and people mistakenly think that the air valve is leaking when it is working, resulting in uncomfortable working environment
