Technical Field

[0001] The utility model relates to the technical field of steering bridges, in particular to a 120T bidirectional traction two-line four-axle steering bridge. Background Art

[0002] The steering axle is an important component on the vehicle chassis. It uses the steering knuckle in the axle to deflect the wheels at both ends to a certain angle to achieve vehicle steering. In addition to bearing the vertical load of the vehicle, it also bears longitudinal force and lateral force and the torque caused by these forces.

[0003] A four-axle steering axle refers to a specially designed axle system in which the vehicle is equipped with four steerable axles (or axles). Compared with traditional two-axle or three-axle steering systems, this design provides greater handling flexibility and stability.

[0004] In the existing technology, four-axle steering axles usually use connecting rods to connect the front and rear ends, but this results in the same rotation angle of the front and rear axles. However, the rear wheels do not actively steer following the steering angle of the front wheels, but rely on the characteristics of the chassis to steer, so that the steering angle of the rear wheels is usually smaller than that of the front wheels. If the deflection angles of the front and rear wheels are the same, the vehicle may deviate due to the same steering angles of the front and rear wheels, making the handling poor. Utility Model Content

[0005] The utility model proposes a 120T two-way traction two-line four-axle steering bridge, which solves the problem in the above technology that the vehicle deviates because the steering angles of the front and rear wheels are the same.

A driven connecting rod is provided at one end of the rear axle, and the other end of the driven connecting rod is movably connected to the outer wall of the second skateboard. A first gear and a second gear are respectively provided inside the guide seat.

[0007] Preferably, a slider 1 is fixedly connected to the top of the first slide, and a slider 2 is fixedly connected to the bottom of the second slide. The slider 1 and the slider 2 are respectively slidably mounted on both sides of the inner wall of the guide seat.

[0008] Preferably, the inside of the guide seat is fixedly provided with a fixed plate, and the inside of the fixed plate is movably provided with a mounting shaft.

[0009] Preferably, the first gear and the second gear are fixedly arranged on the surface of the mounting shaft, and the first gear and the second gear are arranged on the two sides of the fixed plate respectively.

[0010] Preferably, the inside top end of the first sliding plate is provided with a gear slot one, and the inside bottom of the second sliding plate is provided with a gear slot two.

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as attached Figure 1 -Attached Figure 5 As shown, the utility model provides a technical solution: a 120T bidirectional traction two-line four-axis steering bridge, including an underframe 1, a front axle 2 and a rear axle 3 are fixedly installed on the top of the underframe 1, a guide seat 4 is fixedly installed on the top of the underframe 1, and the guide seat 4 is located between the front axle 2 and the rear axle 3. The interior of the guide seat 4 is a hollow structure, and a first slide plate 5 and a second slide plate 6 are movably installed inside the guide seat 4. One end of the front axle 2 is provided with a transmission connecting rod 21, and the other end of the transmission connecting rod 21 is movably connected to the outer wall of the first slide plate 5. One end of the rear axle 3 is provided with a driven connecting rod 31, and the other end of the driven connecting rod 31 is movably connected to the outer wall of the second slide plate 6. A first gear 7 and a second gear 8 are respectively provided inside the guide seat 4, a slider 1 51 is fixedly connected to the top of the first slide plate 5, and a slider 2 61 is fixedly connected to the bottom of the second slide plate 6. The slider 1 51 and the slider 2 61 are respectively slidably installed on both sides of the inner wall of the guide seat 4.

[0025] The effect achieved by the whole embodiment 1 is that the transmission connecting rod 21 is connected with the front axle 2 and the first sliding plate 5 respectively, so that when the front axle 2 is deflected, the transmission connecting rod 21 can pull the first sliding plate 5 to move, and the driven connecting rod 31 is connected with the rear axle 3 and the second sliding plate 6 respectively, and when the rear axle 3 is deflected, the driven connecting rod 31 pulls the second sliding plate 6 to move, and the sliding block one 51 and the sliding block two 61 are installed in the guide seat 4 and can slide, and are limited by the sliding block one 51 and the sliding block two 61, so that the first sliding plate 5 and the second sliding plate 6 can only move horizontally.

[0026] As shown in embodiment 2, Figure 1-5 the inside of the guide seat 4 is fixedly installed with a fixed plate 41, the inside of the fixed plate 41 is movably installed with a mounting shaft 42, the first gear 7 and the second gear 8 are fixedly installed on the surface of the mounting shaft 42, the first gear 7 and the second gear 8 are located on the two sides of the fixed plate 41 respectively, the inner top end of the first sliding plate 5 is provided with a gear slot one 52, the inner bottom of the second sliding plate 6 is provided with a gear slot two 62, the top of the first gear 7 is engaged with the inner top end of the first sliding plate 5, the bottom of the second gear 8 is engaged with the inner bottom of the second sliding plate 6, and the gear modulus of the first gear 7 is greater than that of the second gear 8.

[0027] The effect achieved by the whole embodiment 2 is that when the first gear 7 and the first sliding plate 5 are engaged with each other, the first sliding plate 5 can rotate the first gear 7 when moving, because the first gear 7 and the second gear 8 are fixed on the surface of the mounting shaft 42, the first gear 7 can drive the second gear 8 to rotate together, and because the gear slot one 52 and the gear slot two 62 are located at the upper and lower opposite ends, when the first gear 7 and the second gear 8 rotate together, the first sliding plate 5 and the second sliding plate 6 will move in opposite directions, so that the deflection angles of the front axle 2 and the rear axle 3 are the same, and because the gear modulus of the first gear 7 is different from that of the second gear 8, the modulus of the first gear 7 is greater than that of the second gear 8, so that the moving distance of the second sliding plate 6 is less than that of the first sliding plate 5, so that the deflection angle of the rear axle 3 is less than that of the front axle 2.

[0028] The working principle of this embodiment is as follows: when the angle of the front axle 2 is deflected, the angle of the transmission link 21 is driven to be adjusted, and the transmission link 21 pulls the first slide 5 to move it. Since the first gear 7 is engaged with the first slide 5, the first slide 5 can rotate together with the first gear 7 and the second gear 8 when the first slide 5 moves. The second gear 8 is engaged with the second slide 6 to move the second slide 6 in the opposite direction. When the second slide 6 moves, it can drive the driven link 31 to deflect and pull the rear axle 3 to adjust its angle. Through the cooperation between the transmission link 21 and the driven link 31, the front axle 2 and the rear axle 3 can be deflected at the same time. Since the gear modules of the first gear 7 and the second gear 8 are different, the module of the first gear 7 is larger than that of the second gear 8, the moving distance of the second slide 6 is smaller than the moving distance of the first slide 5, so that the deflection angle of the rear axle 3 is smaller than the deflection angle of the front axle 2, thereby avoiding the situation where the deflection angles between the front axle 2 and the rear axle 3 are the same and the wheels run away.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
