Dual Control Pneumatically Assisted Shift Lever with Roller Dial Switches

Abstract

The invention provides an auxiliary double-control pneumatic gear shift handle of a rolling slide switch. The auxiliary double-control pneumatic 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, an air inlet and outlet structure and a double-control air channel structure, wherein the side working hole valve core combination comprises a side working hole valve core sleeve, a side working hole valve core, a side working hole valve core return spring, a side working hole rubber plug, a side working hole rubber plug return spring and a round ball bearing; in addition, the side control button comprises a sliding part, a rolling part and a sleeve supporting part; the sleeve supporting part is sleeved on a cylinder of the valve body; and the sliding part, the rolling part and the sleeve supporting part are integrated. 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 for a rolling dial switch used in 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 other inf...

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
