Embodiment Construction

[0022] Depend on figure 1 It can be seen that the gear selection structure of the direct-operated six-speed automobile transmission of the present invention limits the reverse gear of the gear position structure provided by the existing six-speed layout. The reverse gear shown in this embodiment is located at the first and second gear selection The position is on the same side, and the shifting block 2 is selected through the shift lever 1. As shown in the figure, it mainly includes the positioning pin 4 of the first and second gears and the vertical pin 19 of the fifth and sixth gears. This structure is mainly included in the shift dial The first and second gear positioning pins 4 that can slide along the cavity below the control cover 3 under the block 2 are moved, and the elastic elements 5 that are installed in cooperation with the first and second gear positioning pins 4 to return the first and second gear positioning pins 4, and the first and second gear positioning pins ...

Abstract

The invention relates to the field of motor vehicle speed changer structures, in particular to a six-gear directly selecting structure for an automobile speed changer. The six-gear directly selecting structure comprises a first-gear and second-gear positioning pin (4), an elastic element (5) and a back gear limiting device; the back gear limiting device comprises a limiting pin (6) contacted and matched with a concave groove of the first-gear and second-gear positioning pin (4), and a rising device connected with the upper end of the limiting pin (6); the limiting pin (6) is glidingly arranged in a sliding cavity of an operating cover (3) above the first-gear and second-gear positioning pin (4); at the initial position, the bottom of the limiting pin (6) is contacted and matched with the bottom of the concave groove of the first-gear and second-gear positioning pin (4) to realize limitation on left and right movement of the first-gear and second-gear positioning pin (4), and upward moves to a position above the sliding cavity of the first-gear and second-gear positioning pin (4) along the sliding cavity of the operating cover (3) under the action of the rising device. By using the scheme, the service life of the monolithic structure can be extended, and the situation of mistakenly putting into the back gear can be avoided basically.

Description

technical field [0001] The invention relates to the field of motor vehicle transmission structures, in particular to a gear selection structure of a direct-operated six-speed automobile transmission. Background technique [0002] With the popularity of automobiles, energy consumption and environmental pollution have been greatly increased, so it is imminent to save energy and reduce emissions for automobiles. For manual mechanical vehicle transmission, the emission of the whole vehicle can be reduced by increasing the number of gears, and at the same time, manual transmission vehicles are also more fuel-efficient and environmentally friendly. Most of the present light vehicle manual transmissions are five forward gears, and the reverse gear and the fifth gear are in the same selection gear position. And for the manual six-speed automobile transmission, the reverse gear needs to be placed in a gear selection position separately, and it is easy to be confused with other selec...
