Embodiment 1

[0039] see Figure 1 to Figure 5, a gearbox gear interlocking structure, including a selector shift dial 1 and a plurality of shift pull plates 2 arranged in parallel, the tops of the plurality of shift pull plates 2 are provided with the same shift select groove 21, so The selector shift dial 1 is slidingly matched with the gear selection groove 21, and the selector shift dial 1 passes through the interlock seat 3 and then drives and cooperates with the shift pull plate 2; the interlock seat 3 includes a locking concave plate 4, The middle part of the locking recessed plate 4 is provided with a lower concave portion 41 that is slidingly matched with the gear selection groove 21, and the locking concave plate 4 is provided with a shift slide 42 perpendicular to the lower concave portion 41. The shifting head 1 passes through the shift sliding port 42 and cooperates with the shift pull plate 2 in transmission; the section of the lower concave portion 41 is a U-shaped structure,...

Embodiment 2

[0041] Embodiment 2 is basically the same as Embodiment 1, and its difference is:

[0042] The interlock seat 3 also includes a guide plate 5 with a flat plate structure, the bottom surface of the guide plate 5 is fixedly connected to the top of the locking concave plate 4, and the middle part of the guide plate 5 is provided with a guide opening 51 corresponding to the shift slide 42 , the selector shift dial 1 sequentially passes through the guide port 51 and the shift slide 42 and then cooperates with the shift pull plate 2; the value range of the width of the shift slide 42 is d+0.5mm- d+1.5 mm.

Abstract

A gearbox gear interlocking structure comprises a gear selecting and changing shifting block and a plurality of parallel gear changing pull plates, wherein a gear selecting groove is formed in the tops of the gear changing pull plates, and the gear selecting and changing shifting block is in sliding fit with the gear selecting groove and is in transmission fit with the gear changing pull plates after penetrating through an interlocking base; the interlocking base comprises a locking concave plate, a lower concave part in sliding fit with the gear selecting groove is arranged in the middle of the locking concave plate, a gear changing sliding opening perpendicular to the lower concave part is formed in the locking concave plate, and the gear selecting and changing shifting block is in transmission fit with the gear changing pull plates after penetrating through the gear changing sliding opening. The gearbox gear interlocking structure is simple in structure, low in production cost, easy to lubricate and long in service life.

Description

technical field [0001] The invention relates to a gear selection and shift interlocking device, in particular to a gearbox gear interlocking structure, which is particularly suitable for simplifying the structure of the interlocking seat, optimizing the lubricating performance, prolonging the service life and reducing the production cost. Background technique [0002] The traditional automotive gearbox gear interlocking seat is a stamping casting, and its shape is mostly a square structure. The upper end is provided with a round hole for interspersing with the gear selection shaft, and the bottom is provided with a guide block groove for the sliding block to slide. Both the inside and outside of the block groove need to be processed, and there is a strict requirement of centerline symmetry. Due to the large number of processing surfaces, the processing technology is complicated and the cost is high, it cannot be widely used in the market. The entire gearbox interlock seat is...
