Description

Fork lever shaft for shifting fork truck

Technical Field

The utility model relates to a fork truck accessory technical field, more specifically say, it relates to a fork truck gear shift's fork lever axle of shifting out.

Background

The shifting fork shaft is an important transmission part in the forklift gearbox, the movable shifting fork is arranged on the shifting fork shaft, when the speed of the forklift needs to be changed, gear switching is firstly carried out, the rotating rod drives the shifting fork on the shifting fork shaft to move axially by controlling the control lever, and the shifting fork enables gears in the gearbox to be separated or meshed, so that gear changing and speed changing are realized.

Because the shifting fork moves, the steel ball moves through the inclined plane of the annular groove of the shifting fork rod, the spring force needs to be overcome, and because the structure is not reasonable, the inclined plane of the groove of the traditional shifting fork rod shaft has larger resistance in the movement, so that the gear shifting and gear shifting are difficult.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the problem that above-mentioned prior art exists, provide a fork truck shifting fork rod axle of fork truck gear shift. The shifting fork rod shaft of the forklift shifting has small shifting resistance and easy and convenient operation.

The utility model discloses technical scheme of shifting out fork axle shaft of fork truck gear shift includes the axis body, the axis body is equipped with connects the shaft hole to and outer annular groove, it includes link and spacing end to connect the shaft hole, outer annular groove includes gear shifting groove and neutral gear groove, gear shifting groove sets up and is flat wall, and gear shifting groove's relative both sides wall setting is slope lateral wall face.

The two inclined side wall surfaces respectively comprise two inclined wall surfaces, the inclined angles of the two inclined wall surfaces are different from each other, and R fillets transition is formed between the two inclined wall surfaces with the different inclined angles.

The neutral gear groove is arranged to be a circular arc bottom wall surface, and two opposite side wall surfaces of the neutral gear groove are respectively arranged to be inclined side wall surfaces.

And R is in smooth transition between the circular arc bottom wall surface of the neutral gear groove and the inclined side wall surface of the neutral gear groove.

The utility model discloses the fork truck gear shift fork rod axle design bearing capacity is big, the ultimate speed is high, the reliability is high, simple and convenient practical. And the structure is simple and reasonable.

Drawings

Fig. 1 is a schematic structural view of an embodiment of a fork lever shaft for shifting a fork truck according to the present invention; FIG. 2 is a partially enlarged schematic view of an outer annular groove portion of a shift lever shaft of the forklift in FIG. 1; fig. 3 is the assembly structure diagram of the fork lever shaft of the fork truck of the utility model.

Detailed Description

In order to facilitate a better understanding of the present invention, the present invention will be further described with reference to the following embodiments and drawings.

As shown in fig. 1 and 2. The utility model discloses fork truck gear shifting's shifting fork rod axle is including setting up in the gear shifting gear groove 2 of its axis body 1, neutral gear groove 3 to and set up in the connection shaft hole etc. of the corresponding one end of axis body. The connecting shaft hole comprises a connecting end 4 and a limiting end 5 which are connected in sequence.

The wall surface of the bottom of the gear shifting groove 2 is a flat bottom wall surface 2a, and two opposite side wall surfaces of the gear shifting groove are respectively arranged into inclined side wall surfaces. The inclined side wall surfaces on two sides of the gear shifting groove 2 respectively comprise two inclined wall surfaces, the inclined angles of the two inclined wall surfaces on each side are different from each other, and R fillets are in transition between the two inclined wall surfaces with different inclined angles. That is, the inclined side wall surface of the shift range groove includes an inclined wall surface portion 2b on the flat bottom wall surface side and an inclined wall surface portion 2c on the shaft body outer peripheral wall surface side, and a junction 21 between the inclined wall surface portion 2b on the flat bottom wall surface 2a side and the inclined wall surface portion 2c on the shaft body outer peripheral wall surface side is R-shaped smooth transition. The flat bottom wall surface 2a of the shift range groove 2 is rounded at a corner R1 with the inclined side wall surfaces on both sides.

The neutral position groove 3 is set as a circular arc bottom wall surface 3a, and two opposite side wall surfaces of the neutral position groove 3 are respectively set as inclined side wall surfaces 3 d. R1 is smoothly transited between the circular arc bottom wall surface 3a of the neutral gear groove and the inclined side wall surface 3d thereof. That is, the junction 31 between the circular arc bottom wall surface 3a of the neutral range groove 3 and the inclined side wall surfaces 3d on both sides thereof is set to be R1 smooth transition. In this example, the circular arc bottom wall surface 3a may be set to R4.

As shown in fig. 3. A shaft body 1 of a shifting fork shaft is inserted and fleed in a shifting fork 6, a steel ball 8 is arranged in a neutral gear groove 3 of the shifting fork shaft, a rotating rod 7 is rotated to drive the shifting fork 6, so that the steel ball axially slides along a corresponding inclined side wall surface of the neutral gear groove under the action of overcoming the elastic force of a corresponding spring 9, and when the steel ball falls into a corresponding shifting gear groove 2, the shifting fork shifts a gear to complete gear shifting of a gearbox.

The rotating rod is rotated to drive the shifting fork, so that the steel ball axially slides along the inclined side wall surface of the corresponding shifting groove under the action of overcoming the elastic force of the spring 9, and when the steel ball falls into the neutral gear groove 3 from the gear groove 2 and then slides into the gear groove 2, the shifting fork shifts the gear to complete the gear shifting of the gearbox.

The utility model discloses the equipment structure of the shifting fork pole axle of fork truck gear shift and corresponding equipment mode and operation mode etc. all can be adapted to similar prior art.
