Description

Test bed for vehicle rear brake hose path design

Technical Field

The present utility model relates to the technical field of test stands for vehicle accessory path design, and more particularly, to a test stand for vehicle rear brake hose path design.

Background

The rear vehicle brake hose is a component part for a rear vehicle wheel brake device, which mainly serves to transfer a brake medium, such as brake fluid, during braking of the vehicle. In general, the rear brake hose is flexible, and its deployment configuration changes with changes in the vehicle movement state and/or use state, so that a path design is required for the rear brake hose to determine reasonable specifications and assembly manners of various parts of the rear brake hose, thereby improving the service life of the rear brake hose.

At present, for the path design of the vehicle rear brake hose, a common method is to obtain specifications and assembly modes of various parts of the vehicle rear brake hose by means of flexible body simulation/emulation software in an early stage of projects. However, one drawback of the conclusions drawn by means of the flexible body simulation/emulation software is that it is difficult to simulate/emulate the influence of the material properties of the elongated body itself of the rear brake hose of the vehicle on the rear brake hose path design, especially if the elongated body is made of multiple material laminates, to draw the correct conclusions. Therefore, in the later stage of the project, a mule car or a sample car is required to be used for checking the brake hose behind the car, which often consumes large manpower and material resources and has a long period. In addition, if the vehicle surrounding parts around the rear brake hose of the vehicle are changed for the vehicle type change, a long period of time is required to wait for the manufacture of the vehicle surrounding parts and then check the real vehicle, so that the starting of the real vehicle check is delayed.

Detailed Description

Various exemplary embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present utility model unless it is specifically stated otherwise.

Techniques and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but should be considered part of the specification where appropriate.

In all examples shown and discussed herein, any specific values should be construed as merely illustrative, and not a limitation. Thus, other examples of exemplary embodiments may have different values.

It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.

The various components/portions of the vehicle, as well as the longitudinal direction, lateral direction, and vertical direction of the test stand for vehicle rear brake hose path design provided by the present utility model, are described herein in a manner that substantially coincides with the longitudinal direction, lateral direction, and vertical direction of the vehicle. Also, herein, terms indicating orientation such as "left" and "right" are used only for simplicity of description.

As is well known, vehicles, particularly passenger cars, generally include left and right front wheels and left and right rear wheels, and accordingly, a vehicle braking system may include a front wheel braking device having a front wheel cylinder/front caliper and a rear wheel braking device having a rear wheel cylinder/rear caliper for braking at least one of the left and right front wheels and at least one of the left and right rear wheels, respectively. The vehicle brake system further includes a brake fluid reservoir and a master cylinder in fluid communication with the brake fluid reservoir, the master cylinder being in fluid communication with the front caliper by way of the vehicle front brake pipe and the rear caliper by way of the vehicle rear brake pipe. In one aspect, the rear wheel brake device further has a rear wheel brake disc fixedly mounted to a rear hub of the at least one rear wheel and a pair of rear wheel brake pads provided on both sides with respect to the rear wheel brake disc, and in response to an action of a vehicle driver depressing a brake pedal, brake fluid (e.g., brake oil) in a brake fluid reservoir flows from a master cylinder to a rear caliper via a vehicle rear brake pipe to push a piston in the rear caliper through hydraulic pressure in the rear caliper to perform a stroke, which in turn causes the pair of rear wheel brake pads to come close to each other so as to contact the rear wheel brake disc, thereby applying a friction braking force to the at least one rear wheel. On the other hand, the vehicle brake system further comprises an Electronic Parking Brake (EPB) having an electric motor for driving the piston for a certain stroke without depending on the hydraulic pressure, the electronic parking brake, in particular the electric motor, being mounted on the rear wheel brake device, in particular on the laterally inner side of the rear wheel brake device, by means of an EPB bracket.

The vehicle rear brake piping includes a vehicle rear brake hose (hereinafter simply referred to as a rear brake hose) and a vehicle rear brake hard pipe (hereinafter simply referred to as a rear brake hard pipe) that are connected to each other, the rear brake hose being flexible, a deployment configuration of which varies with a change in a vehicle movement state and/or a use state, and the rear brake hard pipe being maintained in a substantially fixed deployment configuration so as to satisfy different requirements of a vehicle design for the vehicle rear brake piping.

The rear brake hose presented herein may be used with the same vehicle model, where the same vehicle model may interchangeably use rear wheels of different gauges, which may have tires and/or rims of different widths and/or diameters. Referring to fig. 1, for example, the rear brake hose 10 may include: a flexible elongate tubular body 12; a first fitting 14, such as a rotary (swive) fitting (not shown) that is operable to transfer brake fluid, or a Banjo (Banjo) fitting (shown in fig. 1) that includes a perforated hollow bolt 14a and a ball joint portion 14b that are operable to transfer brake fluid, etc., that is connected to one end of the elongated tubular body 12 to be located at/as one end of the rear brake hose 10, the first fitting 14 being adapted to be engaged to the rear caliper from a laterally inner side of the rear wheel brake device to be in fluid communication therewith; a second fitting 16, such as a tubular fitting having at least partially external splines 16a on a radially outer surface, for transmitting brake fluid, is connected to the other end of the elongated tubular body 12 to be at/as the other end of the rear brake hose 10, the second fitting 16 being adapted to be connected to one end of the rear brake pipe for fluid communication therewith. In addition, there are potential interference locations on the elongated tubular body 12 where the elongated tubular body 12 may interfere with vehicle peripherals around the rear brake hose 10, for which purpose a plurality of sheaths 18a, 18b will be provided on the potential interference locations of the elongated tubular body 12 to improve the scratch or impact resistance of the rear brake hose 10.

Currently, for the path design of the rear brake hose, a common method is to obtain the proper positions, lengths and/or angles of the first joint and the second joint, the proper lengths and/or potential interference positions of the elongated tube body and the like by means of flexible body simulation/emulation software in the early stage of the project. However, one drawback of the conclusions drawn by means of the flexible body simulation/emulation software is that it is difficult to simulate/emulate the effects on the rear brake hose path design due to the material properties of the elongate tube itself, especially if the elongate tube is made from multiple material laminates, to draw the correct conclusions. Therefore, in the later stage of the project, a mule car or a sample car needs to be used for checking the rear brake hose, which often consumes large manpower and material resources and has a long period. In addition, if the vehicle surrounding parts around the rear brake hose are changed for the vehicle type change, a long period of time is required to wait for the manufacture of the vehicle surrounding parts and then check the real vehicle, so that the starting of the real vehicle check is delayed.

The test bench for the path design of the rear brake hose of the vehicle can assist the path design of the rear brake hose more easily, intuitively and rapidly and in early response. Referring to fig. 2, an exemplary test stand 20 may include: a base 22, the base 22 including a flat panel 22a and handles (not shown) provided at both sides of the flat panel 22 a; and first and second supports 24 and 26 adapted to be connected to the base 22, although the first and second supports 24 and 26 are shown in fig. 2 as being detachably connected to the base 22 in place by means of a plurality of positioning holes 22b, respectively, it will be appreciated that the first and second supports 24 and 26 may be non-detachably or detachably connected to the base 22 in place by other means, such as welding, adhesion, and magnetic attraction, respectively. In addition, the first support 24 includes a first connection backplate 24a and a first reinforcing rib 24b standing upright in a state of being connected to the base 22, and the first reinforcing rib 24b serves to support the first connection backplate 24a such that the first connection backplate 24a is stably at an angle, for example, 90 degrees, with respect to the base 22. Similarly, the second support 26 includes a second connection backplate 26a and a second reinforcing rib 26b standing upright in a state of being connected to the base 22, the second reinforcing rib 26b serving to support the second connection backplate 26a such that the second connection backplate 26a is stably at an angle, for example, 90 degrees, with respect to the base 22.

Referring to fig. 2 and 3, the exemplary test stand 20 may further include: a mounting member 28 including a first interface adapted to engage the first joint 14, the first interface being identical in shape to a first aperture of the rear wheel brake for engagement with the first joint 14, the first aperture generally opening on the rear caliper, the first joint 14 in engagement with the first aperture communicating fluid to the rear caliper; a first mold 32 that is at least partially identical in shape to the first vehicle perimeter piece at the perimeter of the first joint 14; and a second mold 34 that is at least partially identical in shape to a second vehicle perimeter piece at a perimeter of the second joint 16 and that includes a second interface 36 (shown in fig. 3) adapted to engage the second joint 16, the second interface 36 being identical in shape to a second aperture formed through the second vehicle perimeter piece for plugging the second joint 16. In the case of the second joint 16 being a tubular joint having at least partially external splines 16a on a radially outer surface, the second aperture will correspondingly have at least partially internal splines on a radially inner edge such that the internal splines of the second aperture mesh with the external splines 16a of the tubular joint in the condition that the second joint 16 is plugged into the second aperture, whereby the second joint 16 is at least laterally fixed relative to the second vehicle peripheral member, the second joint 16 may in turn be connected to said one end of the rear brake hard pipe for fluid communication therewith.

The mounting member 28 and the first model 32 are adapted to be connected to the first support 24, such as the first connection back plate 24a, and the second model 34 is adapted to be connected to the second support 26, such as the second connection back plate 26a, so as to face the mounting member 28 and the first model 32, respectively, so that the positional relationship between the first vehicle periphery, the second vehicle periphery, and the rear brake hose 10, particularly the positional relationship between the first joint 14 and the first vehicle periphery, and the positional relationship between the second joint 16 and the second vehicle periphery, are reproduced in a state in which the first joint 14 is joined to the first interface and the second joint 16 is joined to the second interface 36.

In fig. 2, the first vehicle perimeter piece, which is replicated in shape by the first model 32 in a 1:1 ratio, is a combination of a portion of rear tires, optionally having a width equal to the width of the widest tire of tires of different widths that can be used on the same vehicle model, and a portion of rear rims, optionally having a diameter equal to the diameter of the smallest diameter of rims of different diameters that can be used on the same vehicle model, such that the first model 32 replicates the combination of the portion of rear tires and the portion of rear rims that most likely interfere with the elongated tubular body 12 of the rear brake hose 10.

As already shown in fig. 2 and in more detail in fig. 3, the second vehicle surroundings, which are reproduced by the second model 34 in terms of shape in a 1:1 ratio, are part of a rear wheel house, with the second joint 16 plugged into the second opening, the second joint 16 being at least laterally fixable relative to the part of the rear wheel house. Accordingly, the second interface 36 is configured to be at least partially internally splined (not shown) corresponding to the second aperture.

However, it is understood that the first and second vehicle surrounding parts specifically refer to which part/section of the vehicle is likely to change as the model of the vehicle changes or the test target changes.

As shown in fig. 2, the exemplary test stand 20 may optionally further include: the third model 38, which is at least partially identical in shape to a portion of the EPB bracket, which in a real vehicle is immediately adjacent to the first joint 14. The third model 38 is adapted to be connected to the mounting part 28 to reproduce the positional relationship between the portion of the EPB bracket and the rear brake hose 10, in particular the positional relationship of the portion of the EPB bracket and the first joint 14, even further in a state in which the first joint 14 is joined to the first joint and the second joint 16 is joined to the second joint 36. As explained above, the specific components/portions of the vehicle that the third model 38 replicates in shape in a 1:1 ratio are also likely to vary.

As best shown in fig. 4, the mounting member 28 may alternatively comprise: a support plate 28a adapted to be connected to the first connection backplate 24a, while the first mold 32 may be directly connected to the first connection backplate 24a separately from the support plate 28a or indirectly connected to the first connection backplate 24a by being connected to the support plate 28a, such that the support plate 28a and the first mold 32 together are stably at an angle with respect to the base 22 as the first connection backplate 24 a; and a plurality of mounting blocks, one ends of which along the lateral length thereof are adapted to be connected to different portions of the support plate 28a, respectively, and first interfaces are respectively provided at the other ends of which along the lateral length thereof.

In the case where the first joint 14 is a Banjo joint, since the first interface is identical in shape to the first orifice, the ball joint portion 14b may be joined to the first interface by passing the perforated hollow bolt 14a through the first interface, optionally the same or fewer in number as or than the plurality of mounting blocks, for example, one third model 38 is connected to one or more of the plurality of mounting blocks in each test by means of the joint holes 31 (shown in fig. 2) provided opposite to the first interface.

With continued reference to fig. 4, the support plate 28a is adapted to be connected to the first support 24 and the plurality of mounting blocks are adapted to be connected to the support plate 28a such that different positions of the first interfaces of the plurality of mounting blocks, particularly of the plurality of mounting blocks relative to the first model 32, are capable of characterizing a change in position of the first aperture, particularly of the first aperture relative to the first vehicle periphery, in a state of jounce up and down of the vehicle suspension system, wherein the jounce up and down of the vehicle suspension system is representative of a change in vehicle movement state, as the rear wheel brake assembly will jounce with the vehicle suspension system, the first aperture of the rear wheel brake assembly and thus the first joint 14 of the rear brake hose 10 will also jounce with the vehicle suspension system, such that the deployed configuration of the rear brake hose 10 will change.

For example, with continued reference to fig. 2 and 4, it is possible to provide first to fifth mounting blocks 40a, 40b, 40c, 40d, 40e, i.e. a total of five mounting blocks 40a, 40b, 40c, 40d, 40e, the first interfaces 30a, 30b, 30c, 30d, 30e of which five mounting blocks 40a, 40b, 40c, 40d, 40e, respectively, are capable of characterizing five varying positions of the first aperture in a state of the vehicle suspension system jumping up and down to five different positions, wherein the first mounting block 40a is located vertically uppermost of the support plate 28a with respect to the other mounting blocks 40b, 40c, 40d, 40e, such that the first interface 30a of the first mounting block 40a is capable of characterizing the position of the first aperture in a state of jumping up to an upper limit position on the vehicle suspension system, in particular the position of the first aperture with respect to the first vehicle periphery, the fifth mounting block 40e is located at the lowest position of the support plate 28a in the vertical direction relative to the other mounting blocks 40a, 40b, 40c, 40d such that the first interface 30e of the fifth mounting block 40e is capable of characterizing another position of the first aperture in the state of the vehicle suspension system jumping down to the down-jump limit position, and wherein the second to fourth mounting blocks 40b, 40c, 40d are located between the first and fifth mounting blocks 40a, 40e on the support plate 28a such that the first interfaces 30b, 30c, 30d of the second to fourth mounting blocks 40b, 40c, 40d are capable of characterizing the other three positions of the first aperture in the state of the vehicle suspension system jumping up and down to the three representative positions between the up-jump limit position, respectively, wherein in fig. 2 and 4 the first joint 14 of the rear brake hose 10 is the first interface 30c engaged to the third mounting block 40 c. It will be appreciated that the runout of the first aperture caused by the vehicle suspension system jumping up and down involves runout in the longitudinal direction, the vertical direction, and the lateral direction of the vehicle, and that the five mounting blocks 40a, 40b, 40c, 40d, 40e are connected to different locations of the support plate 28a offset relative to each other in the longitudinal direction and the vertical direction of the support plate 28a to characterize the runout of the first aperture in the longitudinal direction and the vertical direction of the vehicle, and that the lateral lengths of the five mounting blocks 40a, 40b, 40c, 40d, 40e also vary relative to each other to characterize the runout of the first aperture in the lateral direction of the vehicle.

Optionally, the mounting members 28 are provided in the form of a plurality of gauges, each gauge mounting member 28 being adapted to be connected to the first support 24 in a manner that can be replaced by other gauges of mounting members 28, such that different positions of the first interfaces of the plurality of mounting blocks of the respective gauge mounting member 28, in particular of the first interfaces of the plurality of mounting blocks, with respect to the first model 32, are also capable of characterizing a change in position of the first aperture, in particular of the first aperture, with respect to the first vehicle periphery in a state in which the rear wheel brake device is new or has been used to a different extent. In other words, the exemplary test bench 20 is statically used in each test, with only one gauge of mounting member 28 being selected for connection to the first support 24 per test.

For example, two specifications of the mounting member 28 may be provided, with different positions of the first interfaces of the plurality of mounting blocks of the mounting member 28 of the first specification being able to characterize a change in position of the first orifice, in particular a change in position of the first orifice with respect to the first vehicle peripheral component, in a state in which the rear wheel brake device is new and in a state in which the vehicle suspension system is jumping up and down, while different positions of the first interfaces of the plurality of mounting blocks of the mounting member 28 of the second specification being able to characterize a change in position of the first orifice in a state in which the rear wheel brake device is used at limit and in a state in which the vehicle suspension system is jumping up and down. The rear wheel brake device is limited in use and particularly refers to the pair of rear wheel brake pads and the rear wheel brake disc of the rear wheel brake device are worn out completely so as to require replacement. The rear wheel brake is new or has been used to a different extent, representing a change in the state of use of the vehicle, when the rear wheel brake is used to a different extent, the spacing/gap between the pair of rear wheel brake pads and the rear wheel brake disc changes, the thickness of the pair of rear wheel brake pads changes due to wear, and the thickness of the rear wheel brake disc changes due to wear, which in combination result in a displacement of the first aperture on the rear caliper, in particular in the transverse direction of the vehicle with respect to the first vehicle surroundings, the first joint 14 of the rear brake hose 10 also displaces together with the first aperture, such that the deployed configuration of the rear brake hose 10 changes.

Thus, designs are based on characterizing rear wheel brake devices as new or having been used to varying degrees: the size, particularly the lateral thickness, of the support plate 28a of each gauge of the mounting member 28; the size, in particular the lateral length, of the plurality of mounting blocks; and/or the position, in particular the lateral position, of the first interface of the plurality of mounting blocks on the plurality of mounting blocks, respectively.

As an alternative to the embodiment of the mounting part 28 described above, the mounting part may comprise a support plate and for example one mounting block provided with a first interface, the support plate being provided with a chute having a preset shape, the support plate being adapted to be connected to the first support 24, and the mounting block being adapted to be inserted into the chute to be positioned at different positions in the chute and to extend different lengths relative to the chute, so that a change in position of the first interface of the mounting block, in particular a change in position of the first interface relative to the first model 32, can characterize a change in position of the first aperture, in particular a change in position of the first aperture relative to the first vehicle peripheral part, in a state of the vehicle suspension system jumping up and down and/or in a state of the rear wheel brake device being new or having been used to a different extent. For example, the different positions in the chute described in the alternative embodiment of the mounting member include at least five positions where five mounting blocks in the embodiment of the mounting member 28 described above are connected to the support plate 28a, and the different lengths of the mounting blocks extending relative to the chute described in the alternative embodiment of the mounting member may comprehensively account for the position change of the first aperture especially in the lateral direction of the vehicle in the state of the vehicle suspension system jumping up and down, and in the state where the rear wheel brake device is new or has been used to a different extent. The mounting block may be fixed to a desired position in the chute by a number of means at a desired length protruding relative to the chute, for example, a fastening bolt may be threaded through the support plate to protrude into the chute such that the end of the fastening bolt abuts the mounting block.

Alternatively, the mounting member 28, the first model 32, the second model 34, and the third model 38 may be made by three-dimensional printing, for example, the support plate 28a of the mounting member 28, the plurality of mounting blocks, and the third model 38 may be separately three-dimensionally printed, the plurality of mounting blocks connected to the support plate 28a, and the third model 38 mounted to one or more of the plurality of mounting blocks. Alternatively, the three-dimensional printing support plate 28a, the plurality of mounting blocks, and the optional third model 38 may also be integrally printed. The three-dimensional printing material used has a light-weight characteristic, and three-dimensional printing can achieve rapid molding of the mounting member 28, the first model 32, the second model 34, and the third model 38, so that the path design of the rear brake hose 10 can be performed in response to a change of the vehicle type as early as possible. Additionally, the base 22, the first support 24, and the second support 26 may be made of metal to ensure a strong foundation for the example test bench 20. However, the weight of the exemplary test stand 20 remains very light, and the entire test stand 20 may be manually handled, for example, by the handles of the base 22.

Thus, the various components of the exemplary test stand described above may be removed for storage and transport, and the construction of the exemplary test stand may be completed in a short period of time when the exemplary test stand is ready for use. The exemplary test bench can comprehensively simulate the change of the motion state and/or the use state of the vehicle, particularly the change of the position of the first joint of the rear brake hose caused by the up-down jumping of the vehicle suspension system and/or the use of the rear wheel brake device to different degrees at an early stage of the project, so that reliable simulation conclusion can be obtained, and the design is based on the simulation conclusion: taking into account the proper positions, lengths and/or angles of the first and second joints of manufacturing tolerances, for example, where the first joint is a Banjo joint, the neck of the Banjo joint is bent at an angle that the neck of the Banjo joint is bent to further reasonably connect, e.g., clip, to the elongated tube; an appropriate length of the elongated tubular body that takes into account manufacturing tolerances; and/or the gauge of the sheath over the potential interference location. Therefore, the unreasonable design of the path of the rear brake hose of the vehicle can be effectively avoided, the brake hose of the vehicle is prevented from being excessively twisted and the joint is prevented from loosening, and even the leakage of the brake hose of the vehicle is further caused, so that the driving safety is influenced. Also, for the change of the vehicle model, if there is a change in the first vehicle surrounding part and the second vehicle surrounding part, the first model, the second model, and optionally the third model can be quickly made by three-dimensional printing.

It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the utility model. The scope of the utility model is defined by the appended claims.
