Embodiment 1

[0024] Such as figure 1 As shown in a and b, this embodiment relates to an improved gear shift block 1 installed on the transmission fork shaft, including: a through hole 3 for socketing the shift fork shaft, and two holes on both sides of the through hole 3 for The hollow king-shaped groove structure 2 that limits the shift lever and the gear selection return surface 5 for automatic gear selection return.

[0025] The gear selection return surface 5 is a mirror-symmetric V-shaped structure, and the angle between the slope and the horizontal plane ranges from 80° to 85°, and is used for automatic return.

[0026] The hollow king groove structure 2 is located on the back of the gear selection return surface 5, and the direction of the king groove structure 2 is parallel to the symmetry axis of the V-shaped structure of the gear selection return surface 5. The hollow structure is used for shifting gears. Achieve precise guidance.

[0027] The side of the improved shifting bloc...

Embodiment 2

[0030] Such as figure 1 As shown in c and d, this embodiment relates to a function integration device with the above-mentioned improved shift paddle with shift guide and automatic return of gear selection, including: the shift fork actuator located inside the transmission housing The shift fork shaft 8, the above-mentioned improved shifting block 1 sleeved on the end of the shifting fork shaft 8, the positioning pin 9 assembled on the rear housing 11 to match the king-shaped groove structure of the improved shifting block 1, and the assembly The gear selection return pin 10 on the rear housing 11 cooperates with the gear selection return surface of the improved shift paddle 1 .

[0031] Such as figure 2 As shown, the improved shift paddle 1 is cooperatingly arranged on the shift fork shaft 8, which is different from the traditional shift paddle fixed on the manipulator housing of the operating mechanism. The upper end of the improved shift paddle 1 and the positioning The l...

Abstract

The invention belongs to the technical field of automobile gearboxes, and provides a function integrating device with gear shifting guiding and gear-selecting automatic return functions. The device comprises a shifting fork shaft, an improved gear shifting push block, a locating pin and a gear selecting return pin, wherein the shifting fork shaft is located on a shifting fork executing mechanism in a gearbox shell, the improved gear shifting push block is connected to the tail end of the shifting fork shaft in a sleeved mode, the locating pin is assembled on a rear shell and matched with a groove structure in the shape of a Chinese character 'wang' of the improved gear shifting push block, and the gear selecting return pin is assembled on the rear shell and matched with a gear selecting return face of the improved gear shifting push block. The gear shifting guiding function of the shifting fork executing mechanism and the gear selecting return function of a control mechanism are integrated on the device of the shifting fork executing mechanism, an original controller shell and a part of parts are omitted, the size and weight of a whole gearbox are further lowered, and the number of relevant parts of the gearbox can be further reduced.

Description

technical field [0001] The present invention relates to a device in the technical field of automobile transmission, specifically integrating the shift guide function in the shift fork actuator and the gear selection return function in the control mechanism into one device in the shift fork actuator, At the same time, the original manipulator housing and some parts are canceled, so that the volume and weight of the entire transmission can be further reduced, and the number of related parts of the transmission can be further reduced. Background technique [0002] The commonly used longitudinal rear drive transmissions on the market at present, in the process of performing the gear selection return function and the shift guide function, these two actions will be respectively decomposed into the shift fork actuator and the operating mechanism device to realize, so that the steering The overall volume of the mechanism is large, the weight is increased, and the combination of a la...
