Description

Driving assembly on a kind of forklift

Technical field

The utility model relates to a kind of ground means of transportation, particularly relates to the driving assembly on a kind of forklift.

Background technology

Forklift refers to the various wheeled carrying vehicle loading and unloading, pile high, stacking and short range hauling operation to member pallet cargo; Its structure generally comprises vehicle frame, and is arranged on driving assembly, handle assembly and the portal frame system on vehicle frame, and control to drive assembly to run by handle assembly during use, namely vehicle is advanced; High, stacking and handling goods is piled by the tray rack lifting on portal frame system.But existing forklift ubiquity following weak point: drive assembly structure unreasonable, cause vehicle damping weak effect, drive wheel is not enough to the adhesive ability on ground; Likely also exist in vehicular motion that road surface is too sliding and drive wheel skids, or Uneven road and thing jolt situation about dropping.

Summary of the invention

In order to solve the problem, the purpose of this utility model is to provide the assembly of the driving on a kind of forklift, and this driving assembly structure is reasonable, and good damping effect, drive wheel is to the strong adhesion on ground.

In order to realize above-mentioned object, the utility model have employed following technical scheme:

Driving assembly on a kind of forklift, described driving assembly comprises the shock bracket be arranged on vehicle frame, and the driving bearing be arranged in shock bracket, and be arranged on the drive motor, steer motor and the drop-gear box that drive on bearing, and be arranged on the drive wheel on drop-gear box; Described shock bracket comprises the upper bracket and lower bracket that are connected by pipe link, and is set in the damping spring outside pipe link; Described driving bearing location is arranged on the pipe link between upper bracket and lower bracket, and the lower surface of damping spring props up and drives on bearing; Drive between bearing and upper bracket and be also provided with pressurizing cylinder, pressurizing cylinder is fixed on upper bracket, and down, output shaft end props up driving bearing by damper element to the output shaft of pressurizing cylinder.

As preferably, being positioned at by large swing bearing of described drop-gear box is driven on bearing, and the output shaft of drive motor is located in drop-gear box, and drive motor connects drive wheel by drop-gear box; The upper surface of described drop-gear box is provided with gear ring along its edge, and steer motor is meshed with the gear ring on drop-gear box by gear, and steer motor drives drop-gear box to rotate centered by the output shaft of drive motor.

The utility model adopts technique scheme, the driving bearing of the driving assembly of this forklift is for installing drive motor, steer motor and drop-gear box, to drive bearing location and installation in the program in shock bracket, the lower surface of the damping spring in shock bracket props up and drives on bearing; And drive between bearing and upper bracket and be also provided with pressurizing cylinder, the output shaft of pressurizing cylinder props up driving bearing by damper element; During use, on the one hand due to damping spring, and the setting of damper element on pressurizing cylinder, can the damping effect of lifting vehicle on the whole; On the other hand, under the force of pressurizing cylinder, the adhesive ability of drive wheel to ground can be increased, thus the stability that lifting vehicle travels.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in further detail.

Driving assembly on a kind of forklift as shown in Figure 1, described driving assembly comprises the shock bracket be arranged on vehicle frame, and the driving bearing 31 be arranged in shock bracket, and be arranged on the drive motor 32, steer motor 33, drop-gear box 34 and the drive wheel 35 that drive on bearing 31; Described shock bracket comprises the upper bracket 361 and lower bracket 362 that are connected by pipe link 364, and is set in the damping spring 363 outside pipe link 364; Described driving bearing 31 location is arranged on the pipe link 364 between upper bracket 361 and lower bracket 362, and the lower surface of damping spring 363 props up and drives on bearing 31; Drive between bearing 31 and upper bracket 361 and be also provided with pressurizing cylinder 365, pressurizing cylinder 365 is fixed on upper bracket 361, and down, output shaft end is propped up by damper element and drives bearing 31 output shaft of pressurizing cylinder 365; Being positioned at by large swing bearing 37 of described drop-gear box 34 is driven on bearing 31, and the output shaft of drive motor 32 is located in drop-gear box 34, and drive motor 32 connects drive wheel 35 by drop-gear box 34; The upper surface of described drop-gear box 34 is provided with gear ring 341 along its edge, and steer motor 33 is meshed with the gear ring on drop-gear box 34 by gear, and steer motor 33 drives drop-gear box 34 to rotate centered by the output shaft of drive motor 32.

The driving assembly of said structure has following advantage: will drive bearing 31 location and installation in the program in shock bracket, and the lower surface of the damping spring 363 in shock bracket props up and drives on bearing 31; And drive between bearing 31 and upper bracket 361 and be also provided with pressurizing cylinder 365, the output shaft of pressurizing cylinder 365 is propped up by damper element and drives bearing 31; During use, on the one hand due to damping spring 363, and the setting of damper element on pressurizing cylinder 365, can the damping effect of lifting vehicle on the whole; On the other hand, under the force of pressurizing cylinder 365, the adhesive ability on drive wheel 35 pairs of ground can be increased, thus the stability that lifting vehicle travels.
