Description

Technical Field

[0001] The utility model relates to the technical field of vehicle fault simulation devices, in particular to a steering failure simulation training device and a training vehicle. Background Art

[0002] The steering wheel is needed to adjust the direction of the vehicle during driving. Specifically, the steering wheel is connected to the left and right wheels through a steering structure. When the steering wheel is turned to the left, the steering structure controls both the left and right wheels to turn left, and the vehicle turns to the left; when the steering wheel is turned to the right, the steering structure controls both the left and right wheels to turn right, and the vehicle turns to the right.

[0003] Once the steering wheel fails, the vehicle's steering will fail. At this time, if the driver makes a mistake or fails to react in time, it may cause an accident, resulting in property damage and threatening the lives of the people on the vehicle.

[0004] Steering failure does not occur often, so many drivers lack experience in emergency handling when steering failure occurs. If the steering wheel is damaged during driving to practice coping with steering failure, there is a safety hazard. Moreover, the prior art lacks a training device that can safely practice coping with steering failure. Utility Model Content

[0031] This embodiment discloses a training vehicle, which includes a vehicle body and a steering failure simulation training device connected to each other. Figure 1 and Figure 2 As shown, the steering failure simulation training device includes a main operating component and a secondary operating component. The main operating component includes a main steering wheel 1 and a separation device 2, and the separation device 2 can control the main steering wheel 1 and the steering gear (not shown) to be in a connected state or a separated state; the secondary operating component includes a secondary steering wheel 3, a switch structure 4 and a transmission structure, and the switch structure 4 is used to control the separation device 2 to make the main steering wheel 1 and the steering gear in a connected state or a separated state, and the secondary steering wheel 3 is directly or indirectly connected to the steering gear through the transmission structure.

[0032] When the training vehicle is driving normally, the main steering wheel 1 is connected to the steering gear, and the main steering wheel 1 can control the vehicle steering through the steering gear. When the separation device 2 separates the main steering wheel 1 from the steering gear, the main steering wheel 1 cannot control the vehicle steering through the steering gear, which is a steering failure. The driver can practice various operations to deal with steering failure. At this time, the auxiliary steering wheel 3 is connected to the steering gear through a transmission structure, and can control the vehicle steering through the steering gear, ensuring driving safety during the entire practice process and preventing people on the vehicle from being injured.

[0033] The switch structure 4 arranged at the auxiliary steering wheel 3 can control the separation device 2 to make the main steering wheel 1 and the steering gear in a connected state or a separated state, that is, the person in the co-pilot position decides whether the training vehicle is in a steering failure state. The driver may suddenly find that the main steering wheel 1 cannot control the vehicle steering through the steering gear during normal driving, which can better simulate the situation of sudden steering failure and achieve better training effect.

[0034] When the main steering wheel 1 is connected to the steering gear, the connection relationship between the auxiliary operating assembly and the steering gear is not limited. In one structure, when the main steering wheel 1 is connected to the steering gear, the auxiliary steering wheel 3 is disconnected from the steering gear, ensuring that the auxiliary steering wheel 3 does not interfere with normal driving and the driver can control the driving direction. The specific structure for realizing "disconnection of the auxiliary steering wheel 3 from the steering gear" is not limited, and any structure in the prior art that can disconnect the auxiliary steering wheel 3 from the steering gear when the main steering wheel 1 is connected to the steering gear can be used.

[0035] In another structure, when the main steering wheel 1 is connected to the steering gear, the auxiliary steering wheel 3 is also connected to the steering gear. That is, at this time, both the main steering wheel 1 and the auxiliary steering wheel 3 can control the steering of the vehicle through the steering gear. The training vehicle can be, but is not limited to, used for training steering failure. The person sitting in the co-pilot seat accompanies the driver to practice coping with the steering failure, and usually does not meaninglessly interfere with the driver's steering through the auxiliary steering wheel 3. The structure is simple, the components are few, and the cost is low.

[0036] The specific structure of the transmission structure is not limited, as long as the rotation of the auxiliary steering wheel 3 can be transmitted to the steering gear. In this embodiment, the transmission structure includes a chain 51, a main chain gear 52 and a secondary chain gear 53. One end of the chain 51 is connected to the main chain gear 52, and the other end is connected to the secondary chain gear 53. When the main chain gear 52 rotates, it can drive the chain 51 to move, and the movement of the chain 51 can drive the secondary chain gear 53 to rotate synchronously with the main chain gear 52. The main chain gear 52 is directly or indirectly connected to the steering gear, and the auxiliary steering wheel 3 is directly or indirectly connected to the secondary chain gear 53. When the steering of the main steering wheel 1 fails, the secondary steering wheel 3 can control the driving direction through the steering gear to ensure driving safety during training.

[0037] On the basis of the above structure, the separation device 2 is arranged between the main steering wheel 1 and the main chain gear 52, and the structure is more reasonable. When the separation device 2 pushes the main steering wheel 1 upward, the main steering wheel 1 is separated from the steering gear, and the steering gear is only connected to the main chain gear 52, and the steering is controlled by the auxiliary steering wheel 3; after the separation device 2 is reset, the main steering wheel 1 falls until it is connected to the steering gear, and the driving direction can be controlled normally through the main steering wheel 1.

[0038] like Figure 2 and Figure 3 As shown, the transmission structure also includes an adjustment plate 54 for adjusting the tightness of the chain 51, and the elongated adjustment plate 54 is provided with an elongated hole 541 and a snap-in notch 542. Bolts and other connecting parts can slide in the elongated hole 541, so the adjustment plate 54 can adjust the position along the extension direction of the elongated hole 541, and the main operating component is located in the snap-in notch 542. When the adjustment plate 54 is moved, the snap-in notch 542 can push the main operating component away from or close to the secondary operating component, thereby adjusting the tightness of the chain 51 and ensuring smoother transmission between the main chain gear 52 and the secondary chain gear 53. After the chain 51 is adjusted, the bolts and other connecting parts are locked to ensure that the position of the main operating component is stable.

[0039] The specific length of the elongated hole 541 is not limited, and it only needs to be slightly larger than the maximum distance of radial movement of the main operating assembly. The maximum distance of radial movement of the main operating assembly is the maximum range of adjusting the tightness of the chain 51. In order to ensure driving safety, the distance of radial movement of the main operating assembly is limited to prevent the main operating assembly from being separated from the steering gear.

[0040] The specific number of the elongated holes 541 provided on the adjustment plate 54 is not limited. In this embodiment, four elongated holes 541 are provided on the adjustment plate 54. The length, shape and extension direction of all the elongated holes 541 are the same. The four elongated holes 541 form a formation of two rows and two columns. After the bolts and other connecting parts are tightened, the force on the adjustment plate 54 is more balanced, and the main operating component can be more firmly limited.

[0041] Based on the above structure, Figure 1 and Figure 2 As shown, the transmission structure further includes a guide rail portion 55 , in which the chain 51 is disposed and can slide along a track in the guide rail portion 55 , so that the movement trajectory of the chain 51 is more controlled, thereby ensuring that the chain 51 moves more smoothly.

[0042] The specific structure of the guide rail portion 55 is not limited. In the present embodiment, the guide rail portion 55 is a box-shaped structure with openings at both ends. Both ends of the chain 51 pass through the open ends of the guide rail portion 55 respectively. The middle part of the chain 51 is located in the guide rail portion 55, so as to avoid interference between other structures in the training vehicle and the chain 51, and make it safer to use.

[0043] On the basis of the above structure, the transmission structure further includes a steering rod 56. The top end of the steering rod 56 is connected to the main chain gear 52, and the bottom end of the steering rod 56 is connected to the steering gear through a connecting member 8. In this embodiment, the top end of the steering rod 56 forms a bearing seat, and the main chain gear 52 is connected to the bearing seat. The bottom end of the main steering wheel 1 is connected to the top end of the steering rod 56 through a connecting member 8 and a separating device 2, and the separating device 2 controls the connection or disconnection between the main steering wheel 1 and the steering rod 56.

[0044] The specific structure of the connector 8 is not limited, as long as it can achieve a stable connection between the two components. In this embodiment, the connector 8 can be, but is not limited to, a universal joint, with various product specifications, a wide range of applications, and a stable connection structure.

[0045] In order to improve the stability of the secondary chain gear 53, the transmission structure further includes a secondary bearing seat 57, and the secondary chain gear 53 is mounted on the secondary bearing seat 57. The secondary chain gear 53 can be prevented from moving, ensuring that the rotation of the secondary steering wheel 3 can be accurately and timely transmitted to the secondary chain gear 53, and then transmitted to the steering gear through the chain 51 and the main chain gear 52, ensuring that the driving direction is controlled when the main steering wheel 1 fails to turn, and avoiding accidents.

[0046] The specific structure of the separation device 2 is not limited, as long as it can control the main steering wheel 1 and the steering gear to be in a connected state or a separated state. In this embodiment, the separation device 2 is a pneumatic toothed clutch, a part of which is fixedly connected to the top of the steering rod 56, and the other part is fixedly connected to the bottom of the main steering wheel 1. The transmission torque is large, the action is sensitive under the drive of high-pressure gas, and the overall device has high reliability.

[0047] The steering failure simulation training device also includes an air cylinder 6 and an air pipe (not shown), the air cylinder 6 is connected to the pneumatic toothed clutch through the air pipe, and the switch structure 4 can control the opening and closing of the air cylinder 6. When the air cylinder 6 delivers high-pressure gas to the pneumatic toothed clutch through the air pipe, the two parts of the pneumatic toothed clutch are separated, the main steering wheel 1 is disconnected from the steering gear, and the main steering wheel 1 cannot control the steering, simulating the steering failure condition for the driver to practice. At this time, the auxiliary steering wheel 3 is connected to the steering gear through the auxiliary chain gear 53, the chain 51 and the main chain gear 52 to control the driving direction of the training vehicle and ensure safety during training.

[0048] After the training is completed, the switch structure 4 controls the air reservoir 6 to stop delivering high-pressure gas to the pneumatic gear clutch through the air pipe, the pneumatic gear clutch returns to its original position, the main steering wheel 1 is connected to the steering gear, and the training vehicle returns to normal.

[0049] The specific location of the air pipe is not limited. In this embodiment, the steering failure simulation training device further includes a bottom plate 7, and the air pipe is arranged on the bottom plate 7. The air pipe structure is stable and the air supply is smoother. The guide rail part 55 is also connected to the bottom plate 7, which improves the stability of the guide rail part 55, makes the structure more reasonable, and occupies less space.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention.
