Description

Technical Field

[0001] The invention relates to the field of brake systems, in particular to an isolation sleeve for a brake hard pipe and a brake pipeline system having the isolation sleeve for a brake hard pipe. Background Art

[0002] The brake pipe on the car is an important part of the car's braking system, transmitting the pressure of the brake fluid to generate braking force.

[0003] As more and more technologies are applied to automobiles and more and more parts are added, the layout space of the entire vehicle is becoming more and more crowded, especially in the front cabin, which is the main distribution location of brake pipes. As a result, there is very little space for the brake pipes to run, and they are likely to interfere with other components.

[0004] For most of the soft brake hard pipe connection positions, after fixing the hose retaining ring, when the brake hard pipe bolts are re-tightened, the brake hard pipe rotates clockwise, causing the middle section and the end of the brake hard pipe to interfere with the surrounding areas.

[0005] After assembly, the gap between the hard tube and the sheet metal is small due to displacement: the actual vehicle gap value is 2-3mm as shown in the figure. However, considering the limited layout space, the dynamic gap with the brake hose reaches the limit value of 25mm, and the gap with the sliding column reaches the limit value of 20mm. It is impossible to increase the distance from the sheet metal by changing the coordinate point position to offset the displacement change caused by the follow-up rotation.

[0006] The conventional improvement method is to add welding pin fixing points at the interference position, but it is not easy to achieve in a short time due to the long cycle and high cost of changing the body sheet metal design.

[0007] The existing patent 201120454971.5 - Brake hose and brake hose installation structure does not clearly disclose the technical content for solving the above technical problems.

[0038] The specific implementation of the present invention will be further explained in detail below by describing the optimal embodiment with reference to the accompanying drawings.

[0039] An isolation sheath 1 for a brake tube comprises a sheath plate 11; the sheath plate 11 can form an annular structure; the two ends of the sheath plate 11 are connected by a fastening mechanism 2; the isolation sheath 1 disclosed in the present invention is sleeved on a brake tube 5, and has one function of protecting the brake tube 5, and another function of isolating the brake tube 5 to avoid contact between the brake tube 5 and a vehicle body longitudinal beam 4, and to avoid continuous friction between the vehicle body longitudinal beam 4 and the brake tube 5 during subsequent use, which causes the brake tube 5 to be worn and unusable, affecting driving safety.

[0040] The isolation sheath 1 for the brake hard pipe disclosed in the present invention is mainly sleeved on the brake hard pipe 5, plays a good isolation and protection role, prolongs the service life of the brake hard pipe 5, and reduces the wear of the brake hard pipe 5 by the longitudinal beam 4 of the vehicle body.

[0041] In the present invention, the fastening mechanism 2 includes a plug-in block 21 arranged at one end of the sheath plate 11 and a plug-in groove 22 arranged at the other end of the sheath plate 11; when the sheath plate 11 is wrapped in a ring structure, the plug-in block 21 is inserted into the plug-in groove 22; the fastening mechanism 2 plays a good connecting role, facilitating the connection between the two ends of the sheath plate 11, and then facilitating the connection in a ring shape, which is convenient for winding around the brake hard pipe 5 during subsequent use.

[0042] Based on the above design, it can be known that the isolation sleeve 1 disclosed in the present invention can be supplied in the form of a single plate. Such a configuration can reduce the space occupied by the isolation sleeve 1 and avoid the problem of the annular isolation sleeve 1 structure being easy to roll.

[0043] The sheath plate 11 of the present invention is similar to the traditional cable tie structure. When not in use, it is laid flat in the form of a plate structure. When in use, the sheath plate 11 is bent and the two ends of the sheath plate 11 are connected to form a ring structure. It is convenient to use on the arranged brake hard pipe 5.

[0044] It should be emphasized here that the present invention can first perform the pipe laying operation of the brake hard pipe 5, and then perform subsequent isolation protection. In actual use, corresponding installation can be performed on the arranged brake hard pipe 5 as needed, which not only facilitates the installation and fixation of the isolation sheath 1, but also can be arranged in the brake hard pipe 5 close to the vehicle body longitudinal beam 4 as needed, thereby realizing isolation between the brake hard pipe 5 and the vehicle body longitudinal beam 4.

[0045] Furthermore, in the present invention, the plug-in block 21 includes a first plug-in block 211, and a snap-on triangular block 212 is provided at the end of the first plug-in block 211; the plug-in slot 22 includes a triangular snap-in slot 222, and the triangular snap-in slot 222 is connected to the outer side of the sheath plate 11 through a plug-in through slot 221; the plug-in block 21 is plugged into the triangular snap-in slot 222 through the plug-in through slot 221; the vertical cross-sections of the plug-in block 21 and the plug-in slot 22 of the present invention are both arrow-shaped; the end of the plug-in block 21 has a protrusion; a wide groove is provided inside the plug-in slot 22. Based on such a configuration, the plug-in block 21 can be plugged into the plug-in slot 22, thereby realizing the hanging of the plug-in block 21 in the plug-in slot 22.

[0046] In addition, in the present invention, the plug-in blocks 21 are distributed axially along the isolation sheath 1 on the plug-in board, and the plug-in slots 22 are also distributed axially along the isolation sheath 1 on the plug-in board; based on such a setting, it is convenient to achieve a stable connection between the two ends of the sheath plate 11.

[0047] Furthermore, the sheath plate 11 described in the present invention includes a sheath plate body, which is the main structure of the sheath plate 11, and an extrusion layer is provided on the sheath plate body described in the present invention; the extrusion layer can be deformed, so that the isolation sheath 1 can clamp and fix the brake hard tube 5 with different coating thicknesses.

[0048] In addition, the extrusion layer may be a rubber layer or the structure of the raised block 3 described below, and the specific design may be made as required.

[0049] In addition, the extrusion layer in the present invention includes a plurality of raised blocks 3 that are spaced apart in sequence; the raised blocks 3 form a spline structure on the inner wall of the jacket plate body, and the raised blocks 3 are more easily deformed, thereby better extruding and fixing the brake tube 5.

[0050] Furthermore, in the present invention, the outer side surface of the protruding block 3 away from the sheath body is an arc-shaped surface; such a configuration can prevent the outer side surface of the protruding block 3 from having edges and damaging the brake hard tube 5.

[0051] A brake pipe system includes a brake pipe 5; the brake pipe 5 is arranged on a vehicle body longitudinal beam 4, and the brake pipe 5 is distributed on both sides of the vehicle body longitudinal beam 4; the brake pipe 5 of the present invention is connected to the vehicle body longitudinal beam 4, which can ensure the stability of the brake pipe 5 arranged in the vehicle.

[0052] In addition, in the present invention, the isolation sheath 1 is provided on the brake hard tube 5; the isolation sheath 1 plays a good isolation role, preventing the brake hard tube 5 equipped with the isolation sheath 1 from relative movement and wear with the vehicle body longitudinal beam 4.

[0053] In the present invention, it is required to set an isolation sheath 1 on the area of ​​the brake hard pipe 5 close to the vehicle body longitudinal beam 4; in the present invention, the number and location of the isolation sheath 1 can be set as needed.

[0054] It is generally arranged after the brake tube 5 passes through the vehicle body longitudinal beam 4; at the position where the brake tube 5 starts to turn the corner.

[0055] In addition, in the present invention, the brake tube 5 is arranged through the vehicle body longitudinal beam 4 from the side of the vehicle body longitudinal beam 4 close to the ground; such an arrangement facilitates the brake tube 5 to pass through the vehicle body longitudinal beam 4; and at the same time avoids the trouble of opening the vehicle body longitudinal beam 4 to pass the brake tube 5.

[0056] Based on the above design, the brake hard pipe 5 provided by the present invention has a variety of arrangement modes.

[0057] The first one:

[0058] The brake pipe 5 may be first arranged from the vehicle body, and finally led out to the wheel direction through the bottom of the vehicle body longitudinal beam 4.

[0059] Second type:

[0060] The brake tube 5 can be bent into shape and then installed on the vehicle body longitudinal beam 4 from below the vehicle body longitudinal beam 4. This arrangement greatly reduces the trouble of bending the brake tube 5 in real time and reduces the difficulty of installing the brake tube 5 on the vehicle body longitudinal beam 4.

[0061] Furthermore, in the present invention, the brake tube 5 is connected to the vehicle body longitudinal beam 4 via a cable arrangement mechanism 6 ; such an arrangement facilitates the connection between the brake tube 5 and the vehicle body longitudinal beam 4 .

[0062] In the present invention, the cable arrangement mechanism 6 includes a connecting screw 63 arranged on the vehicle body longitudinal beam 4, the connecting screw 63 is fixedly connected to the vehicle body longitudinal beam 4, and a cable arrangement block 61 is provided on the connecting screw 63; the cable arrangement block 61 is screwed on the connecting screw 63; and in the present invention, a snap plate 62 is provided on the cable arrangement block 61; the snap plate 62 is a hook plate that can be snapped onto the brake hard pipe 5 to easily realize the installation and fixation of the brake hard pipe 5.

[0063] Specifically, in the present invention, the snap plate 62 includes a longitudinal plate; one end of the longitudinal plate is connected to the wiring block 61, and the other end is connected to the transverse plate, and a hanging protrusion is provided at the end of the transverse plate away from the longitudinal plate; the transverse plate is parallel and spaced apart from the wiring block 61, and the longitudinal plate is arranged perpendicular to the wiring block 61, and the hanging protrusion is arranged at the end of the transverse plate away from the longitudinal plate. When used subsequently, the transverse plate can squeeze and fix the brake tube 5; at the same time, the hanging protrusion plays a lateral blocking role to prevent the brake tube 5 from detaching from the snap plate 62.

[0064] Furthermore, the cable arrangement mechanism 6 described in the present invention includes a limiting component, which mainly limits the position of the cable arrangement block 61 to prevent the cable arrangement block 61 from rotating autonomously on the connecting screw 63 without the action of external force; in other words, it plays a good limiting role, which facilitates ensuring the stability of the position of the cable arrangement mechanism 6 on the vehicle body longitudinal beam 4.

[0065] In the present invention, the limiting component includes an assembly groove 64 arranged on the wiring block 61; a plug-in card 65 is inserted in the assembly groove 64; a rectangular notch 651 is provided on the plug-in card 65, and the vertical cross-section of the end of the connecting screw 63 is rectangular; the plug-in card 65 is sleeved on the connecting screw 63 through the plug-in card 65; the plug-in card 65 and the assembly groove 64 are interference fit, and the rectangular notch 651 on the plug-in card 65 is inserted into the end of the connecting screw 63; thereby preventing the wiring block 61 from rotating along the connecting screw 63, thereby ensuring the stability of the connection of the wiring block 61 on the connecting screw 63.

[0066] In addition, in the present invention, the plug-in card board 65 can be provided as required.

[0067] specific:

[0068] An isolation sheath 1 for a brake hard pipe comprises a sheath plate 11; the sheath plate 11 can be surrounded by a ring structure; the two ends of the sheath plate 11 are connected by a fastening mechanism 2; the fastening mechanism 2 comprises a plug-in block 21 arranged at one end of the sheath plate 11 and a plug-in slot 22 arranged at the other end of the sheath plate 11; when the sheath plate 11 is surrounded by a ring structure, the plug-in block 21 is plugged into the plug-in slot 22; the plug-in block 21 comprises a first plug-in block 211, and a snap-in triangular block 212 is provided at the end of the first plug-in block 211; the plug-in slot 22 comprises a triangular snap-in slot 222, and the triangular snap-in slot 222 is connected to the outer side of the sheath plate 11 by a plug-in through slot 221; the plug-in block 21 is plugged into the triangular snap-in slot 222 by the plug-in through slot 221; the isolation sheath 1 disclosed in the present invention plays a good isolation and protection role, preventing the brake hard pipe 5 from contacting with the vehicle body longitudinal beam 4 and being worn.

[0069] During normal use, for most of the connection positions of the soft brake tube 5, after fixing the hose retaining spring, when the brake tube 5 bolts are re-tightened, the brake tube 5 will rotate clockwise, causing the middle section and the end of the brake tube 5 to interfere with the surrounding area.

[0070] Conventionally, the design clearance between the brake tube 5 and the vehicle body longitudinal beam 4 is generally required to be no less than 11mm. After assembly, the clearance between the brake tube 5 and the vehicle body longitudinal beam 4 is small due to displacement; the clearance value of the actual vehicle is 2-3mm; but considering the limited layout space, the dynamic clearance with the brake hose reaches the limit value of 25mm, and the clearance with the sliding column reaches the limit value of 20mm. It is impossible to increase the distance with the vehicle body longitudinal beam 4 by changing the coordinate point position to offset the displacement change caused by the heel turn.

[0071] In the present invention, the isolation sheath 1 is arranged in the above-mentioned area of ​​the brake hard tube 5. The thickness of the isolation sheath 1 itself can play a good isolation role.

[0072] The greatest advantage of the present invention is that it can reasonably utilize space and improve the interference between the brake hard tube 5 and the surroundings caused by the rotation of the brake hard tube 5 during assembly.

[0073] 1. Simple assembly; the rubber isolation sheath 1 itself has a fastening mechanism 2, which can be connected to the corresponding position on the brake hard pipe 5 as needed, just like a cable tie.

[0074] 2. Adding an extrusion layer; this structure can realize a brake tube 5 with three or more different coatings.

[0075] It can be added after the brake tube 5 is bent and pressed to lock it immediately.

[0076] After being locked, no axial movement will occur in the brake tube 5 .

[0077] When the present invention is used, when the brake tube 5 is re-tightened, the rubber isolation sheath 1 effectively ensures the designed distance from the test longitudinal beam and plays an isolation role. The brake tube 5 will not produce a Y-direction deviation and will not be close to or even interfere with the test longitudinal beam.

[0078] In the present invention, the interior of the sheath plate 11 can be designed as a flat plate, and such a structure can also achieve isolation and protection for the brake hard pipe 5 .

[0079] However, the scope of application is relatively small. The conventional brake hard tube 5 of the present invention has three coatings, and the coating thicknesses are 3um, 15um, and 120um respectively, and the tube diameters are Φ4.76mm, Φ4.84mm, and Φ5.15mm respectively. The present invention can realize that an isolation sheath 1 can be used on three brake hard tubes 5 with different coatings at the same time through the setting of the protruding block 3, and the axial force is greater than 10N, and there is no movement.

[0080] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
