Abstract

The present invention discloses an impact-resistant and shock-absorbing crawler drive wheel, the drive wheel comprising crawler meshing teeth (1), spokes (2), shock-absorbing holes (3), drive shaft fixing holes (4) and anti-slip grooves (5), and is made of a polycarbonate material containing a carbonate-based high molecular polymer. The drive wheel can absorb most of the impact energy when a robot is subjected to a large impact and is moving, thereby protecting the robot from damage.

Description

Shock-resistant and shock-absorbing crawler belt driving wheel

Technical Field

The invention belongs to the field of reconnaissance robots, and particularly relates to an impact-resistant damping crawler belt driving wheel for a reconnaissance robot.

Background

In military warfare, in order to acquire initiative of warfare, information such as military deployment, weaponry and the like of the opposite party is required to be known, and at the moment, a plurality of hidden places are often required to be scouted, and the scouting task has extremely high risk and endangers life safety of scouting staff at any time. With the continuous improvement of the robot technology and the continuous expansion of the application field, military reconnaissance robots start to appear and put into actual combat, and the reconnaissance robots can be used for helping reconnaissance personnel to finish high-risk reconnaissance work. Because of the specificity of the reconnaissance environment, the topography is complex and the environment is bad. This places high demands on the stability, strength and flexibility of the robot. Therefore, it is necessary to develop a driving mechanism for a scout robot which is light in weight, high in strength, excellent in obstacle crossing performance, and has shock resistance and vibration absorbing performance.

Disclosure of Invention

In order to solve the technical problems, the invention provides an impact-resistant and shock-absorbing track driving wheel which can be used for a light crawler type reconnaissance robot. The driving wheel can absorb most of impact energy when the robot is subjected to larger impact and travels, and the robot is protected from being damaged.

The technical scheme includes that the shock-resistant and shock-absorbing crawler driving wheel comprises crawler meshing teeth (1), spokes (2), shock-absorbing holes (3), driving shaft fixing holes (4) and anti-disengaging grooves (5), wherein the crawler meshing teeth (1) are uniformly distributed on the outermost side of the circumference of the driving wheel and are used for meshing with inner teeth of a crawler (6), and the driving wheel can be prevented from sliding with the crawler (6) while driving the crawler to move. The spoke (2) is a group of diamond spokes formed by two adjacent single spokes, and the middle of the diamond spokes is hollow. The driving wheel is uniformly distributed with 12 groups of diamond spokes around, two adjacent groups of diamond spokes are not connected and are independently supported. When the driving wheel is subjected to large impact or jolt is generated in the running process, the diamond-shaped spoke group can generate a certain amount of deformation to absorb the energy of the impact.

The number of the damping holes (3) is 12, and the damping holes are uniformly distributed between the spokes (2) and the driving shaft fixing holes (4) and are also used for absorbing energy when the driving wheel is subjected to large impact.

The anti-drop belt groove (5) is positioned in the middle of the excircle of the driving wheel and divides the crawler belt meshing teeth (1) into two parts. The anti-disengaging belt groove (5) is matched with the middle protruding part of the inner meshing teeth of the crawler belt (6), and when the crawler belt (6) is matched and tensioned with the shock-resistant and shock-absorbing crawler belt driving wheel, the anti-disengaging belt groove (5) can limit the crawler belt (6) not to be separated from the shock-resistant and shock-absorbing crawler belt driving wheel.

The driving shaft fixing hole (4) is positioned at the circle center of the shock-resistant and shock-absorbing crawler belt driving wheel and is used for being matched with the driving shaft.

The shock-resistant and shock-absorbing crawler belt driving wheel has the beneficial effects that the shock-resistant and shock-absorbing crawler belt driving wheel is made of polycarbonate materials containing carbonate-based high-molecular polymers, and the polycarbonate materials have the characteristics of high strength, high elastic coefficient, high impact strength, high fatigue resistance and the like. The driving wheel adopts a diamond spoke design, so that most impact energy can be absorbed when the robot is impacted and travels greatly, and the robot is protected from being damaged.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in figures 1 and 2, the shock-resistant and shock-absorbing crawler belt driving wheel consists of crawler belt meshing teeth (1), spokes (2), shock absorption holes (3), driving shaft fixing holes (4) and anti-disengaging grooves (5), wherein the crawler belt meshing teeth (1) are uniformly distributed on the outermost side of the circumference of the driving wheel and are used for meshing with the inner teeth of a crawler belt (6), and the driving wheel can be prevented from sliding between the driving wheel and the crawler belt (6) while driving the crawler belt to move.

As shown in fig. 3, the spoke (2) is a group of diamond spokes formed by two adjacent single spokes, and the middle of the diamond spokes is hollow. The driving wheel is uniformly distributed with 12 groups of diamond spokes around, two adjacent groups of diamond spokes are not connected and are independently supported. When the driving wheel is subjected to large impact or jolt in running, the diamond-shaped spoke group can generate a certain amount of deformation to absorb the energy of the impact.

The shock-resistant and shock-absorbing track driving wheel is made of polycarbonate material containing carbonate-based high-molecular polymer.

The present invention is not limited to the examples described in the specific embodiments, and those skilled in the art can obtain other embodiments according to the present invention, which are also within the scope of technical innovation and protection of the present invention.
