Description

Technical Field

[0001] The present application relates to the field of vehicle braking, and in particular to a mechanical brake guide rail device and a brake track. Background Art

[0002] At present, there is generally a trailer system for carrying ship models across the top of the ship test pool. With the continuous increase in demand, the research on ships has become more in-depth, and the speed of ships has gradually exceeded. In order to ensure the safety of high-speed test trailers, braking devices are usually installed on the trailer wheels at the bottom to brake the trailer in emergency situations or special requirements.

[0003] In the related art, the brake device generally includes a brake disc and a brake caliper. The brake caliper clamping the brake disc will generate braking force. When stepping on the brake, the brake caliper is used to clamp the brake disc to slow down until the car stops. The brake disc has a good braking effect and is easier to maintain than drum brakes. However, in the process of the brake caliper clamping the brake disc, a large amount of heat will be generated instantly due to the friction between the friction block and the brake disc, which will increase the temperature of the friction block and the brake disc, resulting in a decrease in the friction coefficient between the friction block and the brake disc surface, and a decrease in the braking force generated, thereby reducing the braking reliability of the brake device, and even causing the brake device to fail, which will cause great safety hazards in the event of failure. In addition, the braking system is currently controlled by electronic control. Although electronic control is convenient, it may fail. Once the test trailer fails, it cannot stop, which will also cause great safety hazards. Summary of the invention

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] The embodiment of the present application provides a mechanical brake guide rail device, which can solve the problem in the related art that the test trailer cannot be decelerated and stopped when the brake device fails or the electric control fails, causing great safety hazards.

[0030] See also Figure 1 As shown, the mechanical brake guide device mainly includes a plurality of brake units 1 and brake blocks 2. The plurality of brake units 1 are arranged side by side and spaced apart along the length direction of the T-shaped guide rail 3. Each brake unit 1 includes two brake plates 10 arranged spaced apart and at least one elastic connection component 11 for connecting the two brake plates 10. The two brake plates 10 are used to be arranged between two oppositely arranged T-shaped guide rails 3, and the two sides are used to clamp the horizontal guide rail surfaces 30 of the two T-shaped guide rails 3. The elastic connection component 11 is used to adjust the clamping force of the two brake plates 10 on the horizontal guide rail surfaces 30 on the corresponding sides by adjusting its own length; the brake block 2 is used to be arranged at the bottom of the vehicle and located in front of the wheel located at the front. The brake block 2 is used to push the brake unit 1 located at the head end to slide relative to the T-shaped guide rail 3 when the vehicle needs to brake, and drive the remaining brake units 1 to slide relative to the T-shaped guide rail 3 in turn, so as to gradually increase the braking force of the vehicle to a preset braking value.

[0031] For details, see Figure 2As shown, the T-shaped guide rail 3 applicable to the present mechanical brake guide rail device includes a vertical guide rail surface 31 and a horizontal guide rail surface 30. The two T-shaped guide rails 3 are symmetrically arranged so that there is a certain gap between the two horizontal guide rail surfaces 30. The two brake plates 10 arranged at intervals are respectively arranged on the top surface and the bottom surface of the two horizontal guide rail surfaces 30, so that the two sides of the two brake plates 10 are used to clamp the two horizontal guide rail surfaces 30. The elastic connection component 11 is located in the gap between the two horizontal guide rail surfaces 30 and is used to connect the two brake plates 10. The elastic connection component 11 itself is particularly elastic and can be moved along its own length. The elastic force is adjusted by changing its own length to stretch or compress, and thus the elastic connection component 11 adjusts the clamping force of the two brake plates 10 on the corresponding side of the horizontal guide rail surface 30 by adjusting its own length, thereby adjusting the friction between the entire brake unit 1 and the T-shaped guide rail 3. If the length of the elastic connection component 11 is shorter, the greater the clamping force between the brake plate 10 and the horizontal guide rail surface 30, when the brake block 2 contacts the brake unit 1, the greater the friction force of the brake unit 1 starting to slide along the T-shaped guide rail 3 driven by the brake block 2, and correspondingly, the greater the braking force the vehicle is subjected to at this time. As the vehicle continues to move forward, the brake block 2 drives the remaining brake units 1 to start sliding relative to the T-shaped guide rail 3 in turn. As more and more brake units 1 slide, the braking force the vehicle as a whole gradually increases. When all brake units 1 slide, all brake units 1 are equivalent to forming a whole. At this time, the braking force the vehicle is subjected to reaches the preset braking force, and is the maximum. As the braking time increases, the speed of the vehicle gradually decreases, and finally stops, completing the braking. The entire braking process is extremely smooth, and the braking force gradually increases with the increase in the number of sliding brake units 1, so that the vehicle speed has a smooth deceleration process, ensuring the safety of braking, and the overall structure of each brake unit 1 is relatively simple, whether it is manufacturing, assembling or adjusting, it is very convenient, and there is no problem of the vehicle being unable to brake and stop after a single brake unit 1 fails, which greatly improves safety.

[0032] For further information, see Figure 3 As shown, each elastic connection assembly 11 specifically includes a disc spring assembly and a connecting member 110, wherein the disc spring assembly is used to be arranged between two horizontal guide rail surfaces 30, and the connecting member 110 is sequentially penetrated through the brake plate 10 located above, the disc spring assembly and the brake plate 10 located below, and the connecting member 110 is used to connect the two brake plates 10, and to compress the disc spring assembly during the connection process so that the two sides of the two brake plates 10 are used to clamp the horizontal guide rail surfaces 30 located on both sides. The connecting member 110 is also used to adjust the clamping force of the two brake plates 10 on the corresponding side of the horizontal guide rail surfaces 30 by adjusting the length of the disc spring assembly.

[0033] Furthermore, the connecting member 110 includes a bolt and a nut, and two adjusting plates 111 are sleeved on the bolt. The two adjusting plates 111 are respectively arranged on both sides of the disc spring assembly and are used to apply compression force to the disc spring assembly under the drive of the nut. Specifically, from the perspective of structural design, each brake plate 10 is rectangular and has a connecting hole thereon. The disc spring assembly, the bolt and the nut are all inserted into the connecting hole. The bolt is inserted into the disc spring assembly. By tightening the nut to compress the length of the disc spring assembly, the two sides of the two brake plates 10 are used to clamp the horizontal guide surfaces 30 on both sides. Since the cross-sectional areas of the bolt and the nut are relatively small, in order to ensure that the disc spring assembly is smoothly compressed during the adjustment process, two adjusting plates 111 are also sleeved on the bolt. The adjusting plates 111 are flat and circular, and their area is larger than the area of ​​the nut and the bolt head. Uniform pressure can be applied to both ends of the disc spring assembly under the rotation drive of the nut. In order to provide reinforcing ribs on each brake plate 10 to ensure structural stability, the number of elastic connection components 11 is determined according to the structure of each brake plate 10, preferably 2 groups, and may be more.

[0034] Furthermore, since each brake unit will slide along the horizontal guide surface 30 under the drive of the brake block 2, and the braking distance of the vehicle during the entire braking process is relatively long compared to a single brake plate 10, in order to ensure the braking effect, both sides of each brake plate 10 must be able to fit perfectly with the horizontal guide surface 30 on the corresponding side as much as possible. Therefore, each elastic connection component 11 also includes a limiting wheel 112, which is sleeved on the bolt and is used to slide and connect with the side walls of the horizontal guide surface 30 on both sides respectively, and the disc spring component includes a plurality of disc springs 113 stacked in sequence along the vertical direction, and the plurality of disc springs 113 are symmetrically arranged on both sides of the limiting wheel 112. Specifically, a limiting wheel 112 is added, which is sleeved on the bolt and located between multiple sets of disc springs 113, so that the force on the brake plates 10 located above and below is uniform. During the entire process of the brake unit 1 sliding relative to the horizontal guide surface 30, the two sides of the limiting wheel 112 are always in contact with the opposite side walls of the two horizontal guide surfaces 30, which plays a good limiting role and can ensure that the position of each brake plate 10 along its width direction will not change during the entire braking process, ensuring smooth braking. In addition, the number of disc springs 113 can be randomly increased or decreased according to actual conditions.

[0035] Furthermore, we know that the T-shaped guide rail 3 itself is generally made of steel, and the brake plate 10 is also made of steel. The hardness of the materials used in both are relatively large. Although in the process of vehicle braking, in order to make the vehicle stop smoothly and in time, it is necessary to apply a sufficiently large braking force to the vehicle, but because the vehicle itself is running at a relatively high speed, if the braking force is very large at the beginning, it will also cause greater danger, making the entire braking process unstable and the experience is relatively poor. Therefore, the mechanical brake guide device also includes four brake strips 4, each brake strip 4 is used to be attached along the edge of one side of the corresponding horizontal guide surface 30, and the length of each brake strip 4 is generally greater than the distance traveled by the vehicle from the beginning of braking to the stop at the maximum speed; it should be noted that the material of the brake strip 4 here is copper, that is, all are copper strips. The reason for using copper strips is that the metal copper itself is soft in texture and has a very smooth surface. Therefore, when adding the brake strip 4, each brake plate 10 is actually attached to the brake strip 4 on the horizontal guide surface 30, and relative friction is also generated between the brake strip 4 when sliding, which is relatively Compared with direct friction with the horizontal guide surface 30, the brake plate 10 is subjected to less friction when rubbing against the brake strip 4, and the smooth surface causes less wear, which can greatly extend the service life of each brake unit 1 and greatly reduce the noise generated during braking. In addition, since the number of brake units 1 is generally more than 10, the vehicle can be stopped completely. Here, by adding the brake strip 4 and appropriately reducing the friction of each brake unit 1, the braking force received by the vehicle during the braking process can be increased steadily and slowly, ensuring the smoothness of the entire braking process and the stability of the vehicle, and reducing safety hazards as much as possible.

[0036] Furthermore, since the brake block 2 is directly installed on the bottom of the vehicle, from the perspective of structural design, the brake block 2 includes a connecting surface 20 and a braking surface 21 vertically arranged at the bottom of the connecting surface 20, the connecting surface 20 is used to be connected to the bottom of the vehicle, and the braking surface 21 is used to be slid between two horizontal guide rail surfaces 30, and is used to push the brake unit 1 at the head end to slide relative to the T-shaped guide rail 3 when the vehicle needs to brake, and drive the remaining brake units 1 to move relative to the T-shaped guide rail 3 in turn.

[0037] Furthermore, in order to achieve better braking, the end of the braking surface 21 close to the braking unit 1 is an inclined surface, and is inclined from top to bottom in the direction away from the braking unit 1. Since the end of the braking surface 21 close to the braking unit 1 is an inclined surface, when it contacts the braking unit 1 at the head end, in addition to giving it a forward thrust, it can also apply a downward pressure to increase the braking effect.

[0038] The present application also provides a brake track, each side of which includes two oppositely arranged T-shaped guide rails 3, each T-shaped guide rail 3 includes a horizontal guide rail surface 30, a plurality of brake units 1 are arranged side by side and spaced apart along the length direction of the T-shaped guide rail 3, each brake unit 1 includes two spaced apart brake plates 10 and at least one elastic connection component 11 for connecting the two brake plates 10, the two brake plates 10 are used to be arranged between the two oppositely arranged T-shaped guide rails 3, and the two sides are used to clamp the horizontal guide rail surfaces 30 of the two T-shaped guide rails 3, the elastic connection component 11 is used to adjust the clamping force of the two brake plates 10 on the horizontal guide rail surfaces 30 on the corresponding sides by adjusting its own length; the brake block 2 is used to be arranged at the bottom of the vehicle and located in front of the wheel located at the front, the brake block 2 is used to push the brake unit 1 located at the head end to slide relative to the T-shaped guide rail 3 when the vehicle needs to brake, and drive the remaining brake units 1 to slide relative to the T-shaped guide rail 3 in turn, so as to gradually increase the braking force of the vehicle to a preset braking value.

[0039] Furthermore, each T-shaped guide rail 3 also includes a vertical guide rail surface 31, and the bottom of the vertical guide rail surface 31 is provided with a plurality of pads 5 arranged at intervals along its length direction, and the pads 5 are used to connect the T-shaped guide rail 3 and the foundation. Among them, when the test trailer is running on this brake track and needs to brake and stop, it contacts the brake unit 1 through the brake block 2, and the vehicle starts to brake after driving the brake unit 1 at the head end to start sliding. As it continues to move forward, the brake block 2 drives the remaining brake units 1 to start sliding relative to the T-shaped guide rail 3 in turn. As more and more brake units 1 slide, the braking force on the entire vehicle gradually increases. When all brake units 1 slide, all brake units 1 are equivalent to forming a whole. At this time, the braking force on the vehicle reaches the preset braking force, and is the maximum. As the braking time increases, the speed of the vehicle gradually decreases, and finally stops and completes the braking.

[0040] In addition, other structures or functions of the brake track correspond one-to-one to the structure of the above-mentioned mechanical brake guide rail device, and will not be repeated here.
