Abstract
The invention provides a steering mechanism of a large-tonnage tray truck, which can effectively solve the problems that the conventional steering mechanism of the large-tonnage tray truck is time-consuming and labor-consuming in steering operation and is highly difficult to operate. The steering mechanism comprises a steering handle and a rotary support, wherein the rotary handle is mounted on a truck frame; a drive motor is mounted on a drive mounting frame; a drive wheel is mounted on a speed reduction box; the steering mechanism of the large-tonnage tray truck is characterized by being provided with a steering control drive device; a corner sensor is mounted at the bottom of the steering handle and connected with the steering control drive device in an electric control way; the steering control drive device is connected with the speed reduction box through a gear transmission device; and the speed reduction box is mounted on the drive mounting frame through the rotary support.
Description
Technical field
The present invention relates to the cargo handing vehicle and make the field, be specially the steering hardware of large-tonnage tray truck.
Background technology
Traditional tray truck steering hardware adopts the mode of mechanical steering; Its structure is seen shown in Figure 1; Steering tiller 1 is connected with drive motor 4 through bolt in three catching plates, 12, three catching plates 12 through bolted connection again, and drive motor 4 is connected with drop-gear box 7; Drop-gear box 7 is connected with the inner ring 14 of revolution support 2 again; And the outer ring 15 of revolution support 2 is rigidly connected with drive installation frame 13, and it is a bearing that revolution supports 2, sees Fig. 2 and Fig. 3; Because revolution is supported the constraint that 2 effect makes drive motor 4 and drop-gear box 7 sleeve mechanisms can break away from drive installation frame 13 and freely rotated, steering tiller 1 drive three catching plates 12, drive motor 4 and drop-gear box 7 and drive wheel 11 entire mechanism are rotated when car load turns to.Its shortcoming is: when this steering structure is applied to the large-tonnage tray truck, because the bigger load that car load bears causes the wheel flutter friction force to strengthen, thereby increased operator's operation easier, wasted time and energy.
Summary of the invention
To the problems referred to above, the invention provides the steering hardware of large-tonnage tray truck, it can effectively solve the problem that steering operation is wasted time and energy, operation easier is big of traditional large-tonnage tray truck steering hardware.
Its technical scheme is such; It comprises steering tiller, revolution support, and said steering tiller is installed on vehicle frame, and drive motor is installed on the drive installation frame; Drive wheel is installed on drop-gear box; It is characterized in that: it is provided with and turns to accessory drive, and said steering tiller bottom is equipped with rotary angle transmitter, and said rotary angle transmitter and the said accessory drive that turns to electricly connect; Saidly turn to accessory drive to pass through gear system to be connected with drop-gear box, said drop-gear box supports through said revolution and is installed on said drive installation frame.
It is further characterized in that:
The said accessory drive that turns to comprises steer motor controller and steer motor, and said rotary angle transmitter is connected with said steer motor controller automatically controlled signal, and said steer motor controller and said steer motor electricly connect;
Said gear drive comprises and turns to little tooth and turn to large fluted disc;
Saidly turn to little tooth to be connected in said steer motor mouth, saidly turn to little tooth and turn to that flute profile is connected with a joggle between the large fluted disc, the said large fluted disc that turns to is connected with said drop-gear box;
Said drop-gear box is installed on the inner ring that said revolution is supported, and outer ring and said drive installation frame that said revolution is supported are rigidly connected.
Compare with traditional tray transport trolley steering hardware; Beneficial effect of the present invention is: its steering tiller separates with heavy weight tray truck drive configuration; Thereby its steering operation is not vulnerable to the influence that transport trolley load and drive wheel and frictional ground force change; Rapid operation, convenience reduce labor intensity of operating staff greatly, raise the efficiency; Wherein the steering tiller bottom is equipped with rotary angle transmitter; When the needs steering operation; Operating personal rotates steering tiller, and rotary angle transmitter passes to the steer motor controller that turns to accessory drive with angular signal, by steer motor controller control steer motor rotation work; And pass through gear drive drive drop-gear box and in revolution is supported, rotate, the drive wheel that drive afterwards is connected in bottom the drop-gear box turns to.
Description of drawings
Fig. 1 is the steering hardware structural representation of traditional tray transport trolley;
Fig. 2 is the structural representation that revolution is supported among Fig. 1;
Fig. 3 is that the A-A of Fig. 2 is to structural representation;
