DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The purpose of the present invention is to provide a track wheel adjustment system and a high-speed track vehicle to solve the problems existing in the above-mentioned prior art, which can prevent the track from jumping teeth or falling off the belt and has higher safety.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Embodiment 1

[0026] This embodiment provides a track wheel adjustment system, such as Figure 1-3 As shown, it includes: a wheel train structure, a detection component 6, an adjustment component 8 and a control component 7. The wheel train structure, the detection component 6, the adjustment component 8 and the control component 7 are all used to be set on the vehicle body 1. The wheel train structure is used to cover the track 9. The detection component 6 and the adjustment component 8 are respectively connected to the control component 7 by signal. The detection component 6 can detect the displacement of at least one track wheel in the wheel train structure, the adjustment component 8 can adjust the position of the track wheel in the wheel train structure, and the control component 7 can calculate the circumference of the wheel train structure according to the detection result of the detection component 6 and control the adjustment component 8 to change the position of the track wheel in the wheel train structure.

[0027] The track wheel adjustment system provided in this embodiment can detect the displacement of the track wheel when the position of the road wheel 3 in the track wheel changes, and transmit the displacement data to the control component 7. The control component 7 can calculate the circumference of the current wheel train structure based on the position change data, and control the adjustment component 8 at the same time, so that the adjustment component 8 changes the position of the track wheel in the wheel train structure (it can adjust the position of only one track wheel, or it can adjust the positions of multiple track wheels at the same time), so that the circumference of the wheel train structure is equal to the circumference of the inner ring of the track 9, so that the wheel train structure can match the inner ring of the track 9, avoiding the occurrence of tooth jumping and belt derailment, and improving safety. Among them, the circumference data of the wheel train structure in a stationary state of a vehicle can be input into the control component 7. When the road wheel 3 in the wheel train structure is displaced, the control component 7 can calculate the circumference data of the current wheel train structure based on the geometric relationship.

[0028] It should be noted that the circumference of the wheel train structure in this embodiment refers to: the total length of the contact surface between each track wheel and the track and the length of the connecting line between two adjacent contact surfaces.

[0029] In one implementation of this embodiment, the gear train structure has an adjusting wheel 5, which is slidably and rotatably connected to the vehicle body 1, and the adjusting component 8 has a free end, which is fixedly connected to the adjusting wheel 5, and the free end can move in the horizontal direction to make the adjusting wheel 5 slide in the horizontal direction. After the control component 7 calculates the circumference of the gear train structure according to the data transmitted by the detection component 6, the free end of the adjusting component 8 moves horizontally under the control of the control component 7, and controls the adjusting wheel 5 to move in the horizontal direction, and changes the circumference of the gear train structure by changing the position of the adjusting wheel 5.

[0030] In the first embodiment of the present invention, the adjustment component 8 includes a tensioning oil cylinder, an adjustment displacement sensor 82, a slide rail and a slider 85. The tensioning oil cylinder and the slide rail are both used to be fixedly connected to the vehicle body 1. The slider 85 is slidably connected to the slide rail. The adjustment wheel 5 is rotatably connected to the slider 85. The piston rod of the tensioning oil cylinder forms a free end and is fixedly connected to the slider 85. The adjustment displacement sensor 82 is fixedly connected to the tensioning oil cylinder. The adjustment displacement sensor 82 is connected to the control component 7 by signal. The adjustment displacement sensor 82 can detect the extension and contraction amount of the piston rod of the tensioning oil cylinder. After the control component 7 calculates the circumference of the wheel train structure according to the data transmitted by the detection component 6, the piston rod of the tensioning oil cylinder is extended. At the same time, the control component 7 determines the extension amount of the piston rod according to the detection result of the adjustment displacement sensor 82, so that the piston rod pushes the slider 85 to slide, thereby changing the position of the adjustment wheel 5 and changing the tension of the track 9.

[0031] In order to improve the reliability of the connection between the slider 85 and the piston rod of the adjustment cylinder 81, in one embodiment of the present embodiment, the adjustment assembly 8 further includes a fixing pin 83, a slot 84 is provided at one end of the tensioning cylinder piston rod, a first plug hole and a second plug hole are respectively provided on two opposite side walls of the slot 84, the first plug hole and the second plug hole are coaxially arranged, the first plug hole connects the inside of the slot 84 and the outside, the second plug hole is a blind hole connecting the inside of the slot 84, a third plug hole connecting the two sides of the slider 85 is provided on the slider 85, the slider 85 can be inserted into the slot 84 so that the axes of the third plug hole, the first plug hole and the second plug hole coincide, and the fixing pin 83 can be simultaneously inserted and detachably connected to the first plug hole, the second plug hole and the third plug hole. Among them, the second plug hole can be set as a threaded hole, and a thread is set at one end of the fixing pin 83, and the detachable connection is achieved by the threaded connection between the fixing pin 83 and the second plug hole.

[0032] In one implementation of the present embodiment, the wheel train structure includes a driving wheel 2, an inducer wheel, a plurality of guide wheels 4 and a plurality of road wheels 3, each road wheel 3 is used to be rotatably connected to the shock absorbing structure of the vehicle body 1 and is located at the bottom of the vehicle body 1, the driving wheel 2 is used to be rotatably connected to the vehicle body 1 and is located higher than each road wheel 3, the driving wheel 2 is used to be connected to the output end of the power system, the inducer wheel forms an adjusting wheel 5, the driving wheel 2 and the inducer wheel are respectively located at two ends of the vehicle body 1, each guide wheel 4 is used to be rotatably connected to the vehicle body 1 and is located between the inducer wheel and the driving wheel 2, and the top of each guide wheel 4 is not lower than the top of the inducer wheel and the driving wheel 2. In the wheel train structure, although the guide wheel 4 can also be made to form the adjusting wheel 5, if the guide wheel 4 is displaced in the vertical direction to change the tension of the track 9, the angle of the track 9 will change. At this time, the number of teeth meshing between the driving wheel 2 and the track 9 will be reduced, thereby increasing the risk of stripping. The inducer wheel is located at one end of the vehicle and is located at a position where the track 9 has an angle. By forming the inducer wheel into the adjusting wheel 5 and adjusting the tension of the track 9 by changing the position of the inducer wheel, the tension of the track 9 can be adjusted without changing the number of teeth meshing between the inner teeth of the track 9 and the outer teeth of the wheel train structure.

[0033] Among them, the driving wheel 2, the inducer wheel, each guide wheel 4 and each road wheel 3 can all be called track wheels, and their specific connection positions and connection methods are the connection positions and methods known to the inventor.

[0034] In the first embodiment of the present embodiment, the detection assembly 6 includes a detection cylinder 61, a detection displacement sensor 62 and an angle displacement sensor. The detection cylinder 61 is used to be fixedly connected to the vehicle body 1. The piston rod of the detection cylinder 61 is hinged to any one of the road wheels 3 in the wheel train structure. The detection displacement sensor 62 is fixedly connected to the detection cylinder 61. The angle displacement sensor is fixedly connected to the road wheel 3. The detection displacement sensor 62 and the angle displacement sensor are both connected to the control assembly 7 by signal. The detection displacement sensor 62 can detect the extension and contraction amount of the piston rod of the detection cylinder 61. The angle displacement sensor can detect the change in the angle of the road wheel relative to the vehicle body after being compressed. By controlling the pressure of the oil in the detection cylinder 61, the piston rod of the detection cylinder 61 can move with the movement of the road wheel 3. Not only can the pressure of the oil be used to play a shock absorbing role, but the control assembly 7 can also detect the position change of the road wheel 3 through the angle displacement sensor, and calculate the current circumference of the wheel train structure according to the position change.

[0035] Specifically, the lower end of the load-bearing oil cylinder is hinged to the balance elbow of the load-bearing wheel 3, and the angle displacement sensor is fixedly connected to the balance elbow. When calculating the track length, the initial circumference of the track (i.e. the circumference of the wheel system structure) can be set as A, and the change in the circumference of the wheel system structure when the angle of the balance elbow changes from the initial state is pre-calculated, and the change in the circumference of the wheel system structure after the wheel system structure rotates through the first unit angle (which can be set to 1rad) is recorded as B, and the change in the circumference of the wheel system structure after the wheel system structure rotates through the second unit angle is recorded as C..., and then it is pre-stored in the control component 7. When the balance elbow is compressed, the angle measured by the angle displacement sensor that the balance elbow swings is X, and the number of unit angles that the balance elbow rotates is n. Then the current circumference of the wheel system structure and the angle of the balance elbow swing have the following relationship, f(x)=AX n +BX n-1 +CX n-2 +……, the formula is preset to the control component 7, and the control component 7 can automatically identify the circumference of the gear train structure according to the rotation angle sensor, and then control the telescopic length of the tensioning cylinder.

[0036] In one implementation of the present embodiment, a plurality of road wheels 3 are sequentially arranged along the front-to-back direction of the vehicle body 1, the road wheel 3 near the front end of the vehicle body 1 is the first road wheel 31, and the road wheel 3 near the rear end of the vehicle body 1 is the second road wheel 32, and two detection components 6 are arranged, and the detection cylinders 61 of the two detection components 6 are respectively fixedly connected to the two ends of the vehicle body 1, and the piston rods of the two detection cylinders 61 are respectively hinged to the first road wheel 31 and the second road wheel 32. When the vehicle is going uphill or downhill, the first road wheel 31 near the front end of the vehicle body 1 and the second road wheel 32 near the rear end of the vehicle body 1 will be subjected to greater force and undergo greater displacement. By detecting the displacement of these two wheels, the control component 7 can more accurately determine the position change of each track wheel in the wheel train structure.

[0037] In one implementation of the present embodiment, the track wheel adjustment system provided in the present embodiment further includes a hydraulic oil source 11 and a solenoid valve group 12, both of which are fixedly connected to the vehicle body 1, and the hydraulic oil source 11 is connected to the input end of the solenoid valve group 12, and the solenoid valve group 12 has a first output end and two second output ends, the first output end is connected to the adjustment cylinder 81, and the two second output ends are respectively connected to the two detection cylinders 61, and the hydraulic oil source 11 and the solenoid valve group 12 are both connected to the control component 7 by signal. The control component 7 can control the hydraulic oil source 11 to pass hydraulic oil into the solenoid valve group 12 according to the data detected by the monitoring displacement sensor, the angle displacement sensor and the adjustment displacement sensor, and the solenoid valve group 12 can open the first output end or the second output end under the control of the control component 7 to allow the oil to enter the adjustment cylinder 81 or the detection cylinder 61.

[0038] In order to facilitate the disassembly and replacement of the hydraulic oil source 11 and the solenoid valve group 12 , in one implementation of this embodiment, the hydraulic oil source 11 and the solenoid valve group 12 are both connected to the vehicle body 1 by screws.

[0041] The high-speed tracked vehicle provided in this embodiment can prevent the track 9 from jumping teeth or falling off the belt by setting the track wheel adjustment system in the first embodiment, and has higher safety.

The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope.
