The invention aims to provide a steering mechanism of a single-crawler traveling mechanism, which can solve the problem that the single-crawler traveling mechanism is difficult to steer.

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a steering mechanism for single track running gear, contains swing arm pivot and running-board pivot, swing arm, deflector, running-board, the reset torsion spring that is used for fixing in the frame, wherein:

swing arm pivot and running-board pivot are fixed in single track running gear's frame, the one end and the swing arm pivot of swing arm are connected to can rotate around the swing arm pivot, the other end of swing arm is through the round pin hub connection with the one end of deflector, the other end of deflector is connected with the one end of running-board through the round pin axle, the other end and the running-board pivot of running-board are connected, and can rotate around the running-board pivot, the torsional spring that resets is arranged in swing arm pivot and/or running-board pivot, the effect is for making deflector and running-board reply upper portion initial position. The bottom of the guide plate is provided with a guide rib which forms a certain angle with the advancing direction and is used for providing lateral tension when the guide plate is in contact with the ground. The steering mechanisms are symmetrically arranged on two sides of the single-crawler traveling mechanism.

The invention has the beneficial effects that:

1. when the pedal on one side of the single-track traveling mechanism is stepped on and the guide ribs at the bottom of the guide plate are in contact with the ground, additional lateral tension except friction resistance can be provided, so that the single-track traveling mechanism can steer to the side on which the pedal is stepped on.

2. The steering mechanisms are symmetrically arranged on two sides of the frame, and when the guide plates on the two sides are simultaneously contacted with the ground, auxiliary braking force can be provided.

3. The steering mechanism is simple in structure, convenient to operate and reliable in work.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described below clearly with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are one embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The following is described in further detail in conjunction with the accompanying drawings:

a steering mechanism for a single-track traveling mechanism comprises a swing arm rotating shaft 1, a pedal rotating shaft 2, a pedal 3, a guide plate 4, a pin shaft 5, a pin shaft 6, a clamping ring 7, a clamping ring 8, a swing arm 9, a reset torsion spring 10 and a reset torsion spring 11. The swing arm rotating shaft 1 and the pedal rotating shaft 2 are connected and fixed with a frame 12, one end of a swing arm 9 is connected with the swing arm rotating shaft 1 and can rotate around the swing arm rotating shaft 1, the other end of the swing arm 9 is connected with one end of a guide plate 4 through a pin shaft 6, the swing arm 9 and the guide plate 4 can rotate relatively around the pin shaft 6, the other end of the guide plate 4 is connected with one end of a pedal 3 through a pin shaft 5, the tail parts of the pin shaft 5 and the pin shaft 6 are limited by an outer clamping ring, the guide plate 4 and the pedal 3 can rotate relatively around the pin shaft 5, the other end of the pedal 3 is connected with the pedal rotating shaft 2 and can rotate around the pedal rotating shaft 2, a clamping ring 8 is clamped in a clamping groove at the end part of the swing arm rotating shaft 1 and used for limiting the axial position of the swing arm 9, a clamping ring 7 is clamped in a clamping, one end of the reset torsion spring is inserted into a reset torsion spring fixing hole 16 of the guard plate 13, the other end of the reset torsion spring is arranged at the lower part of the swing arm 9, and the reset torsion spring 10 is arranged to generate torque which presses the limiting pin 15 on the swing arm 9. The reset torsion spring 11 is sleeved on the pedal rotating shaft 2, one end of the reset torsion spring 11 is inserted into the reset torsion spring fixing hole 17 of the protective plate 13, the other end of the reset torsion spring is arranged at the lower part of the pedal 3, and the reset torsion spring 11 is arranged to generate upward lifting moment on the pedal 3, so that the pedal 3 can be reset upwards when not being stepped on. The bottom of the guide plate 4 is provided with a guide rib 18 which forms a certain angle with the advancing direction and is used for providing lateral tension when the guide plate is in contact with the ground, and the arrangement direction of the guide ribs at the bottom of the guide plate symmetrically arranged at the other side of the single-track walking mechanism is opposite to that of the guide ribs at the bottom of the guide plate. This steering mechanism symmetrical arrangement is in the frame both sides, when single track running gear need turn to, the driver need step on the running-board 3 that wants to turn to one side with certain power, running-board 3 rotates certain angle round running-board pivot 2, running-board 3 promotes deflector 4, deflector 4 promotes swing arm 9 again, make swing arm 9 overcome the elasticity downswing of reset torsion spring 10, thereby drive deflector 4 syncline below motion, make deflector 4 bottom and direction muscle 18 and ground contact, under the guide effect of deflector 4 bottom direction muscle 18, ground can give 4 lateral thrust of deflector, thereby realize that single track running gear turns to the action to 3 one side of running-board. After the steering is finished, the pedal 3 is released, and the steering mechanism returns to the initial position under the action of the reset torsion spring 10 and the reset torsion spring 11.
