Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of traction steering assistance, and particularly relates to a power traction vehicle's assisted steering mechanism. BACKGROUND

[0002] The traction vehicle is a general carrier between the vehicle head and the vehicle box which is pulled by tools, that is, the vehicle head can be separated from the original vehicle box to pull other vehicle boxes, and the vehicle box can also be separated from the original vehicle head to be pulled by other vehicle heads.

[0003] However, in actual application, most of the existing traction vehicles are usually manually adjusted in moving direction by workers during use, but in the case of heavy load, the workers manually adjust, which will produce great resistance, not only time-consuming and laborious, but also poor flexibility of adjustment, which is not conducive to popularization and use.

[0004] Therefore, the technical personnel in the art provides an assisted steering mechanism of a power traction vehicle to solve the problems in the background art. CONTENT OF THE UTILITY MODEL

[0005] In order to solve the problem that the workers manually adjust, which will produce great resistance, not only time-consuming and laborious, but also poor flexibility of adjustment, which is not conducive to popularization and use in the case of heavy load in the background art, the present application provides an assisted steering mechanism of a power traction vehicle.

[0006] The assisted steering mechanism of the power traction vehicle provided by the present application adopts the following technical scheme: a traction plate is provided, four connecting columns are fixedly connected to the top side of the traction plate, a connecting frame is rotatably sleeved on the front side of the traction plate, a same traction wheel is rotatably installed on the inner walls of the two sides of the connecting frame, a motor is fixedly connected to the left side of the connecting frame, the traction wheel is fixedly sleeved on the output shaft of the motor, a connecting mechanism is arranged at the top end of the connecting frame, a handle is fixedly connected to the top end of the connecting mechanism, an electric control button is fixedly installed on the left side of the handle, the electric control button is electrically connected with the motor, and four universal wheels are installed on the bottom side of the traction plate.

[0007] Preferably, the connecting mechanism comprises a connecting sleeve and a connecting rod, the connecting rod is slidably connected with the inner wall of the connecting sleeve, and the handle is fixedly connected with the top end of the connecting rod.

[0008] Preferably, a plug is slidably connected to the front side of the connecting sleeve, and a plurality of bolt holes are formed in the front side of the connecting rod.

[0009] Preferably, a spring is fixedly connected to the front side of the connecting sleeve, and the spring is fixedly connected with the plug.

[0010] In summary, the present application has the following beneficial technical effects:

[0011] 1. By setting up a handle, the external transport vehicle loaded with goods is connected to the traction plate via a connecting column. The electric control button controls the output shaft of the motor to drive the traction wheel to rotate. When the traction wheel rotates, it can achieve a traction effect. At the same time, during the traction movement, by grasping the handle, the rotation angle of the connecting frame can be controlled by the connecting mechanism, thereby controlling the direction of the traction wheel. When the transported goods are too heavy, the rotatable characteristic of the connecting mechanism can be used to rotate the connecting mechanism at an appropriate angle. This leverage principle can save effort when adjusting the direction of the traction wheel, improve the flexibility of operation, save time, and facilitate its widespread use.

[0012] 2. By setting up a connecting sleeve and a connecting rod, and utilizing the sliding characteristics between the connecting sleeve and the connecting rod, the length of the connection between the two can be increased. When the overall length of the connection between the connecting sleeve and the connecting rod increases, the torque between the two will also increase, thereby further improving the applicability in the process of operating using the lever principle.
