Description
Technical field
The present invention relates to vehicle speed variation system, particularly, relate to a kind of selector.Further, the present invention relates to a kind of transmission for vehicles operating mechanism that comprises described selector.In addition, the invention still further relates to a kind of vehicle that comprises described transmission for vehicles operating mechanism.
Background technique
Known ground, transmission for vehicles operating mechanism is used for operation transmission to realize the gear switch of vehicle, thus the travelling speed of change vehicle and reversing etc.Transmission for vehicles operating mechanism is divided into cane type shift device operating mechanism and remote operation formula transmission control (those skilled in the art are also referred to as " indirect operation formula transmission control ").
Due to reasons such as vehicle and automobile chassis layouts, the speed changer of a large amount of vehicle vehicles is not arranged near operating seat, such as passenger vehicle, heavy truck, part car etc., and there is a segment distance apart from driver's compartment in speed changer now.In this case, in order to realize gearshift object, need to adopt remote operation formula transmission control, briefly, remote operation formula transmission control is exactly between speed changer and speed change lever, to have increased the intermediate transmission mechanism of a set of relative complex, to realize the object of block selecting gearshift.
Remote operation formula transmission control is rather ripe at present, and described intermediate transmission mechanism is divided into two classes substantially, i.e. flexible shaft transmission mechanism and drive link driving mechanism.For example, with regard to the transmission control of employing flexible shaft transmission mechanism, driver's operation is by selector (those skilled in the art are also referred to as " gear lever assembly " or " control rod assembly "), via flexible shaft transmission mechanism (generally comprising block selecting flexible axle and gearshift flexible axle), be transferred to the rocking arm (typically comprising block selecting rocking arm and gear-shifting rocker arm) arranging on speed changer, and then drive driving lever to realize block selecting gearshift.In addition, with regard to the transmission control of employing drive link driving mechanism, its operating principle is also like this.In above-mentioned remote operation formula transmission control, the agent structure of selector is known ground, for example selector of the disclosed prior art of utility model patent CN201841956.
