Yes. The vehicle restraining

jigs

12 and 12 are provided with a length adjusting mechanism 13 such as a turnbuckle capable of adjusting the length according to the vehicle length on one end side. Further, a tie rod 14 for connecting the left and right pair of vehicle restraining

jigs

12 and 12 is provided at the center in the length direction. The tie rod 14 includes a length adjusting mechanism 15 such as a turnbuckle for adjusting the distance between the vehicle restraining

jigs

12 and 12 in accordance with the vehicle width at the center in the length direction.

The

vehicle restraining jigs

12, 12 are connected to the seat belt fixing pillar 2 via the first link mechanism 16 so that one end side in the length direction is pivotable, and the other end side via the second link mechanism 17. The pole 10 is pivotally coupled.

2A, the first link mechanism 16 is attached to the inner surface 2a of the seat belt fixing pillar 2 so that the shaft 18 is positioned in the vicinity of the vehicle center-of-gravity point position 6. As shown in FIG. Further, the shaft 21 of the second link mechanism 17 is also attached to the pole 10 so as to be positioned at substantially the same height as the vehicle center-of-gravity point position 6. The vicinity of the vehicle center-of-gravity point position 6 refers to a position as close as possible to the vehicle center-of-gravity point position 6.

As shown in FIG. 3, the first link mechanism 16 includes a shaft 18, a bearing member 19 that rotatably supports the shaft 18, and the bearing member 19 attached to the inner surface 2 a of the seat belt fixing pillar 2. Mounting member (hereinafter referred to as a pillar mounting member) 20.

And the 1st link mechanism 16 can rotate in the inner surface 2a of the seatbelt fixed pillar 2 with the shaft 18, the bearing member 19, and the pillar attachment member 20 at the one end side of the vehicle restraining jigs 12 and 12 in the length direction. It is connected.

The pillar attaching member 20 is formed in a long plate shape corresponding to the seat belt fixing pillar 2 and is attached to the inner surface 2a of the seat belt fixing pillar 2 instead of the seat

belt fixing portions

4 and 5.

Further, the second link mechanism 17 includes a shaft 21 disposed on the other end side of the vehicle restraining jig 12 and a bearing member 22, and is attached to the pole 10 via the bearing member 22.

Next, an example of a method for attaching the vehicle restraining jig 12 to the seat belt fixing pillar 2 will be described with reference to FIGS. 3 (A), (B), and (C).

In this example, first, as shown in FIG. 3A, one end side of the pair of left and right vehicle restraining jigs 12 and 12 is attached to the center portion of the pillar attachment member 20 via the shaft 18 and the bearing member 19. . On the other hand, the seat

belt fixing portions

4 and 5 are removed from the seat belt fixing pillar 2.

Then, as shown in FIGS. 3B and 3C, the pillar attaching member 20 is attached to the inner surface 2a of the seat belt fixing pillar 2. The pillar mounting member 20 is attached to the seat belt fixing pillar 2 by overlapping the screw holes 23 of the seat belt fixing pillar 2 and the screw holes 24 of the pillar mounting member 20 and screwing the screws 25 into these screw holes 23 and 24. It is done by doing. In FIG. 3C, 26 indicates a vehicle frame, 27 indicates a vehicle interior, and 28 indicates the exterior of the vehicle interior.

The vehicle restraint device 11 according to the first embodiment is configured as described above. When the vehicle restraint device 11 is used, first, the vehicle 1 is placed on a roller 7 of a chassis dynamometer as shown in FIG. One end of the vehicle restraining jig 12 is connected to the belt fixing pillar 2 via the first link mechanism 16 so that the shaft 18 of the first link mechanism 16 is positioned in the vicinity of the vehicle center-of-gravity point position 6. On the other hand, the other end side of the vehicle restraining jig 12 is attached to the pole 10 via the second link mechanism 17, and the height of the pole 10 is adjusted so that the shaft 21 of the second link mechanism 17 is positioned at the vehicle center of gravity position. 6 is set to a position substantially the same height as 6, and the vehicle restraining jig 12 is held in a substantially horizontal state.

Then, the vehicle 1 is restrained by a pair of left and right vehicle restraining jigs 12 and the roller 7 is rotated to perform various tests of the vehicle 1.

Since one end side of the vehicle restraining jig 12 is coupled to the highly rigid seat belt fixing pillar 2, the vehicle restraining jig 12 can restrain the vehicle securely and firmly.

Further, one end side of the vehicle restraining jig 12 is rotatably coupled to the seat belt fixing pillar 2 via the first link mechanism 16 in the vicinity of the vehicle center-of-gravity point position 6, and the other end side of the vehicle restraining jig 12 is connected. The vehicle (translational) longitudinal motion is restrained but the vehicle (rotation) pitching motion because it is pivotally coupled to the pole 10 via the second link mechanism 17 at a position substantially the same height as the vehicle center-of-gravity point position 6. And the vehicle (translation) vertical movement is free, and it is possible to realize the vehicle behavior in which the vertical load approximates the road. Since the vertical load applied to the tire can be made to coincide with the traveling state including the acceleration / deceleration state, it becomes possible to perform a test including the fuel consumption by the mode operation, the vehicle behavior of the exhaust gas test and the vehicle performance test.

Furthermore, since the length of the vehicle restraining jig 12 can be adjusted by the length adjusting mechanism 13, the length can be arbitrarily adjusted according to the vehicle length of the vehicle 1.

Since the pole 10 can be adjusted in at least one direction of the vehicle width direction and the vehicle length direction, various sizes can be obtained by adjusting the vehicle restraining jig 12 according to the vehicle width, vehicle length, etc. of the vehicle 1. It can be applied to other vehicles.

[Second Embodiment]
FIG. 4 shows a second embodiment. In the aspect of the first embodiment, this embodiment includes a restraint force detector 29 between the second link mechanism 17 and the pole 10, and the restraint force detector 29 detects the restraint force of the vehicle. The attachment position of the restraint force detector 29 is not limited between the second link mechanism 17 and the pole 10, but between the vehicle restraint jig 12 and the second link mechanism 17, or between the first link mechanism 16 and It may be between the seat belt fixed pillars 2 or the like, and may be any place as long as the restraining force of the vehicle 1 can be reliably detected. According to the vehicle restraint device 11 of the present embodiment, since the restraining force of the vehicle 1 can be detected, in addition to the effects of the first embodiment, the characteristics on the vehicle spring can be measured and analyzed and evaluated.

[Third Embodiment]
5 to 9 show a third embodiment. In this embodiment, as shown in FIG. 5, the first link mechanism 31 that rotatably couples one end side of the vehicle restraining jig 12 to the seat belt fixing pillar 2 is connected to one end side of the vehicle restraining jig 12. A cylindrical shaft portion 32 that is rotatably attached and a shaft support arm 33 that attaches the shaft portion 32 to the seat belt fixing pillar 2 are provided.

As shown in FIGS. 6 to 8, the shaft support arm 33 is formed in a substantially T shape, and is provided with a shaft portion 32 on one end side and attached to the seat belt fixing pillar 2 on the other end side with a screw 34. . The shaft support arm 33 is capable of adjusting the mounting height position by selectively using a plurality of screw holes 35 formed in the seat belt fixing pillar 2.

The shaft support arm 33 is formed in a substantially T shape so that when the shaft support arm 33 is attached to the seat belt fixing pillar 2, the position of the shaft portion 32 is set to the front and rear of the vehicle with respect to the position of the seat belt fixing pillar 2. This is to prevent the shaft portion 32 from interfering with the driver's seat or the passenger seat by shifting in the direction. Accordingly, the shape is not limited as long as interference can be suppressed. The shaft support arm 33 and the shaft portion 32 may be extendable and adjustable in length.

Moreover, the 2nd link mechanism 41 which attaches the other end side of the vehicle restraint jig 12 to the pole 10 so that rotation is possible is provided in the other end side of the vehicle restraint jig 12, as shown in FIG.5 and FIG.9. The shaft portion 42 and a bearing member 43 that rotatably supports the shaft portion 42 are attached to the pole 10 via the bracket 44.

The bracket 44 is attached to the pole 10 so as to be movable up and down by a height adjusting mechanism (not shown), and the height position of the second link mechanism 41 can be adjusted.

A length adjusting mechanism 45 such as a turnbuckle is provided at the end of the pair of left and right vehicle restraining jigs 12 on the bearing member 43 side. When the rotation operation body 46 at the center is rotated, the length adjustment mechanism 45 rotates the

bolts

47, 48 connected to the left and right of the rotation operation body 46 in the left and right directions, so that the vehicle restraining jig 12 is moved to the vehicle. The length of the vehicle restraining jig 12 can be adjusted according to the vehicle length. Since other configurations are the same as those in the first and second embodiments, the same components are denoted by the same reference numerals, and redundant description is omitted.

Next, an example of how to use the vehicle restraint device 11 of the third embodiment will be described.

First, the shaft support arm 33 of the first link mechanism 31 on one end side of the vehicle restraining jig 12 is attached to a desired height position of the seat belt fixing pillar 2. If necessary, the length of the shaft support arm 33 and the length of the shaft portion 32 are adjusted to prevent the shaft portion 32 of the first link mechanism 31 from interfering with the driver's seat and the passenger seat.

Next, the other end side of the vehicle restraining jig 12 is attached to the pole 10 via the second link mechanism 41 and the bracket 44.

Then, the length and width of the pair of left and right vehicle restraining jigs 12 and 12 are adjusted to restrain the vehicle 1, and the roller 7 is rotated to perform various tests on the vehicle 1.

The vehicle restraint device 11 of the third embodiment can rotate the one end side of the vehicle restraint jigs 12 and 12 to the seat belt fixing pillar 2 as well as the length adjustment and width adjustment of the vehicle restraint jigs 12 and 12. Since the position of the shaft portion 32 of the first link mechanism 31 attached to the vehicle is separated from the position of the seat belt fixing pillar 2 by the shaft support arm 33, the shaft portion 32 of the first link mechanism 31 is moved to the driver seat or the passenger seat. Can be prevented.

Further, since the second link mechanism 41 is attached to the pole 10 so as to be movable up and down, the second link mechanism 41 is moved up and down, and the second link mechanism 41 is adjusted to the height position of the first link mechanism 31 to restrain the vehicle. There is an effect that various tests can be performed by holding the tool 12 in a substantially horizontal state. Since other configurations and effects are the same as those of the vehicle restraint device according to the first and second embodiments, a duplicate description is omitted.

[Fourth Embodiment]
10 and 11 show a fourth embodiment. In the aspect of the first embodiment, the present embodiment includes a first link mechanism 51 instead of the first link mechanism 16.

The first link mechanism 51 has a length-adjustable reinforcement jig 52 that connects and reinforces a pair of pillar attachment members 20 attached to the inner surfaces 2 a of the left and right seat belt fixing pillars 2 in the vehicle 1, and the reinforcement jig 52. And a connecting jig 53 that rotatably connects the vehicle restraining jig 12 in all directions on the outer rear side of the vehicle 1.

The reinforcing jig 52 includes a cross member that connects the pair of pillar mounting members 20. The reinforcing jig 52 includes a length adjusting mechanism 54 that adjusts the length thereof. The reinforcing jig 52 is attached to the pair of pillar mounting members 20 so that the arrangement thereof can be adjusted in the vehicle height direction of the vehicle 1 (for example, substantially the same height as the vehicle center-of-gravity point position 6).

The connecting jig 53 includes a pillow ball 55 that is mounted and fixed near one end of the reinforcing jig 52, a spherical bearing portion 56 that accommodates the pillow ball 55, and a connection jig that connects the bearing portion 56 to the vehicle restraining jig 12. 57.

Examples of use of the vehicle restraint device 11 of the present embodiment will be described with reference to FIGS.

For example, in the vehicle 1 having the rear seat door 121, first, the door 121 is removed or the door 121 is opened and fixed by the door restraining jig 58. Alternatively, the driver's seat and the passenger's door 120 of the vehicle 1 are removed or the 120 door is opened and fixed with the door restraining jig 58.

Examples of the door restraining jig 58 include various restraining jigs such as fixing by a suction cup. However, the door restraining jig 58 may be fixed so that the rear seat door 121 and the vehicle restraining jig 12 do not come into contact with each other. The constraining jig may be applied. Further, the location and quantity of the door restraining jig 58 are not particularly limited as long as they can be fixed so that the rear seat door 121 and the vehicle restraining jig 12 do not come into contact with each other.

Next, one end of a vehicle restraining jig 12 inserted into the vehicle 1 is connected to both the connecting jigs 53 of the first link mechanism 51 attached in the vehicle 1 obliquely from the outer rear side of the vehicle 1. The vehicle restraining jig 12 connected to the connecting jig 53 is rotatable in all directions on the outer rear side of the vehicle 1. Next, the other end side of the vehicle restraining jig 12 is rotatably coupled to the pole 10 via the second link mechanism 17 at a position substantially the same height as the vehicle center-of-gravity point position 6.

Next, the lengths of the vehicle restraining jigs 12 and 12 are adjusted by the length adjusting mechanism 13, and the distance between the vehicle restraining jigs 12 and 12 is adjusted by the length adjusting mechanism 15. Further, the height of the pole 10 on the pedestal portion 100 on the floor surface, the arrangement in the front-rear direction or the width direction of the vehicle 1, and the connection direction with respect to the vehicle restraining jig 12 are appropriately adjusted.

After the vehicle 1 is restrained as described above, various tests of the vehicle 1 are performed by rotating the roller 7 of the chassis dynamometer.

According to the vehicle restraint device 11 of the present embodiment described above, one end side of the vehicle restraint jig 12 is rotatably coupled to the inner surface 2a of the seat belt fixing pillar 2 by the link mechanism 51, while the vehicle restraint jig 12 The other end side is pivotally coupled to the pole 10 by the link mechanism 17. Therefore, similarly to the vehicle restraint device 11 of the first embodiment, the vehicle 1 can be reliably restrained firmly. In addition, although the vehicle (translation) longitudinal motion is restricted, the vehicle (rotation) pitching motion and the vehicle (translation) vertical motion are free, and the vehicle behavior in which the vertical load approximates to the road can be realized. Therefore, since the vertical load applied to the tire can be matched with the running state including the acceleration / deceleration state, it is possible to perform the test including the fuel consumption by the mode driving, the vehicle behavior of the exhaust gas test and the vehicle performance test.

In particular, in the present embodiment, the vehicle restraining jig 12 is reinforced in the vehicle 1 via the connecting jig 53 obliquely from the rear rear side of the vehicle 1 in a state where the rear seat door 121 of the vehicle 1 is removed or opened and fixed. The tool 52 can be coupled in the vicinity of one end. Therefore, it becomes easy to adjust the connection position of the vehicle 1 and the vehicle restraining jig 12 to the vicinity of the vehicle center-of-gravity point position 6 without being affected by the shape of the rear seat or the trunk room. Further, the modification of the vehicle 1 that is necessary when the vehicle 1 is used in the vehicle test apparatus can be minimized. Thereby, the test preparation time can be shortened.

Further, the vehicle restraining jig 12 is rotatable in all directions outside the vehicle 1 by the connecting jig 53 in the vicinity of the pillar mounting member 20 (in the present embodiment, in the vicinity of both ends of the reinforcing jig 52). . Therefore, the vehicle restraining jig 12 can be arbitrarily set up to a height in the vicinity of the vehicle center-of-gravity point position 6 according to the insertion space of the vehicle restraining jig 12 in the vehicle 1. As a result, road running that may occur during the vehicle 1 test when the vehicle 1 is forced to be restrained at a height position away from the vehicle center-of-gravity point position 6 in order to avoid physical buffering with the rear seat or the trunk room of the vehicle 1. The pitching motion (for example, overswing) of the vehicle 1 different from the above can be suppressed.

The pair of pillar mounting members 20 facing each other in the vehicle 1 are connected and reinforced by a reinforcing jig 52. Further, since the vehicle restraining jig 12 is connected to both ends of the reinforcing jig 52 via the connecting jig 53, the moment (torque) of the vehicle restraining jig 12 with respect to the reinforcing jig 52 is reduced. The load factor is reduced. Thereby, the deformation | transformation of the reinforcement jig | tool 52 and the deformation | transformation and fracture | rupture of the pillar attachment member 20 accompanying this can be prevented. Further, since the length of the reinforcing jig 52 can be adjusted by the length adjusting mechanism 54, the reinforcing jig 52 can arbitrarily cope with the size of the vehicle 1. Further, since the reinforcing jig 52 can be adjusted in the vehicle height direction of the vehicle 1 by the pair of pillar mounting members 20, the arrangement of the reinforcing jig 52 is arranged at the vehicle center-of-gravity point position 6 according to the size of the vehicle 1. It can be set arbitrarily up to a nearby height.

As is clear from the above description, the vehicle restraint device 11 of the present embodiment is effective for restraining, for example, a four-door type vehicle 1.

In addition, the 1st link mechanism 51 does not necessarily require the reinforcement jig | tool 52, when the pillar attachment member 20 can fully ensure rigidity by selection of the constituent material. In this case, for example, the pillow ball 55 of the connecting jig 53 is attached and fixed to a short fixed shaft provided integrally with the pillar mounting member 20.

[Fifth Embodiment]
FIG. 12 shows a fifth embodiment. In this embodiment, the restraint force detector 29 is provided between the vehicle restraining jig 12 and the second link mechanism 17 in the aspect of the fourth embodiment, and the restraining force detector 29 detects the restraining force of the vehicle. . The attachment position of the restraint force detector 29 is not limited between the vehicle restraining jig 12 and the second link mechanism 17, but between the second link mechanism 17 and the pole 10, It may be between the seat belt fixed pillars 2 or the like, and may be any place as long as the restraining force of the vehicle 1 can be reliably detected. According to the vehicle restraint device 11 of the present embodiment as described above, the restraining force of the vehicle 1 can be detected. Therefore, in addition to the effects of the fourth embodiment, the characteristics on the vehicle spring can be measured and analyzed.

[Sixth Embodiment]
13A and 13B show a sixth embodiment. In the present embodiment, one end side of the vehicle restraining jig 12 is attached to the left and right seat belt fixing pillars 2 of the vehicle 1 via the first link mechanism 51 at a position in the vicinity of the vehicle center-of-gravity point position 6 obliquely from the inner rear side of the vehicle 1. Except that they are coupled so as to be rotatable, they are the same as the fourth embodiment.

An example of use of the vehicle restraint device 11 of the present embodiment will be described with reference to FIG.

For example, when the test vehicle is a vehicle 1 having a back door exemplified by a hatchback type vehicle, the back door of the vehicle 1 is opened and the door is fixed by a door restraining jig 58 (not shown). Next, one end of the vehicle restraining jig 12 inserted into the vehicle 1 is connected to the connecting jig 53 of the first link mechanism 51 attached in the vehicle 1 from the inside rear obliquely of the vehicle 1. The vehicle restraining jig 12 connected to the connecting jig 53 is rotatable in all directions on the inner and rear side of the vehicle 1. Next, as in the fourth embodiment, the other end side of the vehicle restraining jig 12 is rotatably coupled to the pole 10 via the second link mechanism 17 at a position substantially the same height as the vehicle gravity center position 6. Is done. Further, the lengths and intervals of the vehicle restraining jigs 12 and 12 are adjusted by the

length adjusting mechanisms

13 and 15, respectively. The height of the pole 10, the arrangement in the front-rear direction or the left-right direction, and the connection direction with the vehicle restraining jig 12 are also adjusted. After the vehicle 1 is restrained as described above, various tests of the vehicle 1 are performed by rotating the roller 7 of the chassis dynamometer.

As described above, the vehicle restraint device 11 of the present embodiment also has one end side of the vehicle restraint jig 12 rotatably coupled to the inner surface 2a of the seat belt fixing pillar 2 by the link mechanism 51, while the vehicle restraint jig 12 The other end side is pivotally coupled to the pole 10 by the link mechanism 17. Therefore, similarly to the vehicle restraint device 11 of the fourth embodiment, the vehicle 1 can be restrained reliably and firmly, and the vehicle (translation) longitudinal motion is restrained but the vehicle (rotation) pitching motion and the vehicle are restrained. (Translation) Vertical movement is free, and it is possible to realize vehicle behavior in which the vertical load approximates to the road.

In particular, in the present embodiment, the vehicle restraining jig 12 can be coupled to the vicinity of one end of the reinforcing jig 52 in the vehicle 1 from the inside rear obliquely of the vehicle 1. Accordingly, the connection position of the vehicle 1 and the vehicle restraining jig 12 can be adjusted to the vicinity of the vehicle center-of-gravity point position 6 while reducing physical buffering with the rear tire house, rear door opening, and the like of the vehicle 1. It becomes easy. Moreover, since the modification of the vehicle required when the vehicle 1 is used for the vehicle test apparatus can be minimized, the test preparation time can be shortened.

Furthermore, the vehicle restraining jig 12 is rotatable in all directions inside the vehicle 1 by the connecting jig 53 in the vicinity of the pillar mounting member 20 (in the vicinity of both ends of the reinforcing jig 52 in this embodiment). The vehicle restraining jig 12 can be arbitrarily set up to a height in the vicinity of the vehicle center-of-gravity point position 6 according to the insertion space of the vehicle restraining jig 12 in the vehicle 1. Therefore, it may occur during the vehicle 1 test when the vehicle 1 is forced to be restrained at a height position away from the vehicle center of gravity position 6 in order to avoid physical buffering with the rear tire house of the vehicle 1 and the rear door opening. Pitching movement (for example, overswing) of the vehicle 1 different from road driving can be suppressed.

The pair of pillar mounting members 20 facing each other in the vehicle 1 are connected by a reinforcing jig 52, and the vehicle restraining jig 12 is connected to both ends of the reinforcing jig 52 via a connecting jig 53. It has become. Therefore, the pillar attachment member 20 is reinforced similarly to the fourth embodiment. Furthermore, since the load factor of the moment (torque) of the vehicle restraining jig 12 with respect to the reinforcing jig 52 is reduced, it is possible to prevent deformation of the reinforcing jig 52 and deformation and breakage of the pillar mounting member 20 accompanying this. Note that the length of the reinforcing jig 52 can arbitrarily correspond to the size of the vehicle 1 by the length adjusting mechanism 54.

As is apparent from the above description, the vehicle restraint device 11 of this embodiment is effective for restraining a vehicle 1 having a two-door type vehicle 1 or a rear door, for example.

Also in the present embodiment, the first link mechanism 51 does not necessarily require the reinforcing jig 52 when the pillar mounting member 20 can sufficiently ensure rigidity by selecting the constituent material. Also in this case, as described above, a mode in which the pillow ball 55 of the connecting jig 53 is mounted and fixed on a short fixed shaft provided on the pillar mounting member 20 may be employed.

It is reinforced. The vehicle outside fixing device 83 is arranged on the floor surface 9 so that the position of the vehicle outside fixing device 83 can be adjusted in any one of the vehicle width direction, the vehicle length direction, and the vehicle height direction of the vehicle 1 like the pole 10 of the first to eighth embodiments. Installed.

First, the pillar attaching member 20 in which one end of the vehicle restraining jig 82 is connected to the connecting jig 53 of the first link mechanism 51 is attached to the inner surface 2 a of the seat belt fixing pillar 2. As a result, the vehicle restraining jig 82 is rotatable in all rear directions in the vehicle 1 in the vicinity of the vehicle center-of-gravity point position 6. Next, the other end side of the vehicle restraining jig 82 is coupled to the coupling jig 53 of the link mechanism 84 supported in the rear seat chamber 122 at a position substantially the same height as the vehicle gravity center position 6. The lengths of the vehicle restraining jigs 82 and 82 are adjusted by the length adjusting mechanism 13, and the position of the vehicle exterior fixing device 83 is any one of the vehicle width direction, the vehicle length direction, and the vehicle height direction of the vehicle 1.

Although restrained, the vehicle (rotation) pitching motion and the vehicle (translation) vertical motion are free, and it is possible to realize vehicle behavior in which the vertical load approximates the road.

In particular, in this embodiment, in addition to the effects of the sixth embodiment, when the test vehicle is the vehicle 1 having the rear seat door 121, the link mechanism in which the other end of the vehicle restraining jig 82 is connected. Since 84 is supported by the outside fixing device 83 through the opening 123 of the rear seat door 121, the modification of the vehicle 1 subjected to the vehicle test can be reduced.

Further, since the reinforcing jig 52 and the first reinforcing jig 86 can be attached to the

attachment members

20 and 85 so as to be adjustable in the vehicle height direction, the arrangement of the reinforcing jig 52 and the first reinforcing jig 86 is possible. Can be arbitrarily set up to a height in the vicinity of the vehicle center-of-gravity point position 6 according to the size of the vehicle 1.

Further, since the other end of the vehicle restraining jig 82 is connected to both ends of the first reinforcing jig 86 via the connecting jig 53, the vehicle restraining jig with respect to the first reinforcing jig 86 is connected. The load factor of the moment (torque) 82 can be reduced, and the deformation of the first reinforcing jig 86 and the accompanying deformation and breakage of the pillar mounting member 85 can be prevented.

Since the pair of mounting members 85 is supplementarily connected and reinforced by the second reinforcing jig 87 having a further length adjustment, the first reinforcing jig 86 is further connected while the pillar mounting member 85 is reinforced. Stable support.

Also, as shown in FIG. 26, it is preferable to provide a restraining force detector 29 in the vehicle restraining jig 82 as in the fifth embodiment. According to this aspect, since the binding force of the vehicle 1 can be detected, a measurement signal of the binding force in the front-rear direction of the vehicle 1 can be detected.

Furthermore, as shown in the figure, the vehicle restraining jig 82 may be provided with a vibration damping device 89 that attenuates the natural vibration of the jig 82. As the vibration attenuating device 89, a known vibration attenuating device attached non-concentrically or non-coaxially to the vehicle restraining jigs 12, 82 can be cited.

The vibration damping device 89 is detachably attached to the vehicle restraining jig 82, an elastic member 89b exemplified by a rubber and a spring detachably connected to the member 89a, and detachably attached to the member 89b. A weight-adjustable weight 89c connected to the

[Tenth embodiment]
27 and 28 show a tenth embodiment. In the first to ninth embodiments, the vehicle restraint device 11 of the present embodiment includes a deflection absorbing mechanism 90 that absorbs the deflection of the vehicle restraint jigs 12 and 82 that occurs during the test of the vehicle 1 using the chassis dynamometer.

27 includes a jig receiving portion 901 having a buffer material 900 that elastically contacts a vehicle restraining jig that has been bent in the direction of gravity during the test, and the jig receiving portion 901 horizontally. And a support column 902 that is supported to be rotatable in a direction or a vertical direction. As the buffer material 900, a thick plate made of a known elastic member exemplified by polyethylene or the like is applied.

The column portion 902 is erected on a pedestal portion 903 installed on the floor surface 9 so that the position of the vehicle 1 can be adjusted in any of the vehicle width direction, the vehicle length direction, and the vehicle height direction.

According to the present embodiment described above, since the bending absorbing mechanism 90 is arranged, in addition to the effects of the first to ninth embodiments, the restraining jig 12 that bends in the direction of gravity when the vehicle 1 is tested by the chassis dynamometer. , 82 can be absorbed by the cushioning material 900.

For example, even if the vehicle 1 is suddenly decelerated due to a brake operation test or the like and the vehicle restraining jigs 12 and 82 are bent, the bending is absorbed by the buffer material 900 on the jig receiving portion 901. The influence of the restraining force of the force detector 29 on the measurement signal can be reduced. Further, the vehicle restraining jigs 12 and 82 can be prevented from being damaged due to the buckling phenomenon.

In particular, the jig receiving portion 901 is disposed under the vehicle restraining jigs 12 and 82 (in the direction of gravity) and can rotate in the horizontal direction or the vertical direction. The said bending can be absorbed corresponding to the bending from a direction.

Further, as shown in FIG. 28, the jig receiving portion 901 may be provided with a pair of receiving portions 904 having a buffer material 900 that elastically contacts the vehicle restraining jig that has been bent in the horizontal direction. According to this aspect, the impact of the vehicle restraining jigs 12 and 82 that bend in the gravity direction and the vehicle width direction is reliably absorbed by the cushioning material 900 of the pair of receiving portions 904, and the influence of the restraining jigs 12 and 82 is reduced. Further, it becomes possible to detect a measurement signal of the reduced binding force. Moreover, the damage by the buckling phenomenon of the vehicle restraining jigs 12 and 82 can be prevented more effectively.

Note that, as shown in FIG. 29, in this embodiment as well, the vibration damping device 89 may be detachably attached to the vehicle restraining jigs 12 and 82 as in the ninth embodiment. According to this aspect, since the natural vibration of the vehicle restraining jig 82 generated during the test of the vehicle 1 is attenuated by the vibration damping device 89, the restraining force that further reduces the influence of the vehicle restraining jig 82 generated during the test of the vehicle 1. This measurement signal can be detected by the binding force detector 29.

[Eleventh embodiment]
FIG. 30 shows an eleventh embodiment. The vehicle restraint device 11 of this embodiment is a vibration damping device 89 that attenuates the natural vibrations of the vehicle restraining jigs 12 and 82 generated during the test of the vehicle 1 by the chassis dynamometer in any aspect of the first to tenth embodiments. Is provided.

As the vibration damping device 89, there is a vibration damping device that is detachably attached to the vehicle restraining jigs 12, 82 in a non-concentric or non-coaxial manner as shown in FIG.

The vibration damping device 89 shown in FIG. 30A is detachably connected to an attachment member 891 that is detachably attached to the vehicle restraining jigs 12 and 82 and an outer surface of a lower end portion 891c of the attachment member 891. An elastic member 892, a length-adjustable shaft portion 893 having one end detachably connected to the elastic member 892, and a weight-adjustable weight portion 894 detachably connected to the other end of the shaft portion 893. Is provided.

The attachment member 891 is detachably connected to the upper end 891a detachably attached to the vehicle restraining jigs 12, 82, a main body 891b detachably connected to the upper end 891a, and the main body 891b. A lower end 891c.

The main body 891b can rotate in all directions around the upper end 891a (attachment position with respect to the vehicle restraining jigs 12 and 82). In order to enable the omnidirectional rotation, for example, an upper end 891a having a pillow ball at the upper end is applied.

Since the main body 891b is detachable from the upper end 891a, the main body 891b having a different length may be arbitrarily selected. If the main body 891b is provided with a length adjusting mechanism, the main body 891b need not be replaced.

The lower end 891c is rotatable in the horizontal direction. The lower end 891c can be freely rotated in the horizontal direction when, for example, an internal thread portion that is screwed with the lower end of the main body 891b is applied.

As the elastic member 892, for example, an elastic member such as an elastic rubber or a coil spring that is applied to a known vibration damping damper is applied. As the shaft portion 893, for example, a length-adjustable screw shaft screwed to the elastic member 892 is applied. As the weight part 894, for example, a well-divided and well-known weight screwed to the shaft part 893 is appropriately applied.

According to the present embodiment described above, since the vibration damping device 89 is arranged, in addition to the effects of the first to tenth embodiments, the natural vibration of the vehicle restraining jigs 12 and 82 generated during the test of the vehicle 1 is vibrated. Since it is attenuated by the damping device 89, the restraint force detector 29 can detect a restraint force measurement signal in which the influence of the vehicle restraint jig 82 is reduced.

For example, even when the vehicle 1 subjected to the vehicle test suddenly accelerates or decelerates, the damping rate of the natural vibration of the vehicle restraining jigs 12 and 82 is reduced by the vibration damping device 89, and the

jigs

12 and 82 Since the amplitude time is shortened, the influence on the measurement signal of the binding force detector 29 can be suppressed.

Further, since the vibration damping device 89 can be detachably attached non-concentrically or non-coaxially away from the vehicle restraining jigs 12 and 82, both ends such as the vehicle restraining jigs 12 and 82 are fixed. Thus, it can be easily attached to a rod-shaped member whose natural frequency is difficult to adjust. In addition, since the weight of the weight portion 894 can be adjusted even after the attachment, the natural vibration frequency and the damping rate of the vehicle restraining jigs 12 and 82 can be easily adjusted.

In particular, in the vibration damping device 89, the attachment member 891 has an upper end portion 891a with respect to the vehicle restraining jigs 12, 82, a main body portion 891b with respect to the upper end portion 891a, and a lower end portion 891c with respect to the main body portion 891b. The elastic member 892 is detachable from the lower end portion 891c, the shaft portion 893 is detachable from the elastic member 892, and the weight portion 894 is detachable from the shaft portion 893. Therefore, the mounting position of the upper end 891a with respect to the vehicle restraining jigs 12, 82, the length of the main body 891b, the shaft 893, the elastic member 892, the elastic force of the elastic member 892, and the weight of the weight 894 are arbitrarily set individually. It becomes possible. Therefore, the adjustment corresponding to the natural vibration frequency of the vehicle restraining jigs 12 and 82 can be flexibly performed. And the effect of the said adjustment increases further by making the lower end part 891c rotatable in the horizontal direction.

As shown in FIG. 30B, an elastic member 892 is additionally detachably connected to the outer surface of the lower end portion 891c of the attachment member 891 so as to face the existing elastic member 892, and this elastic member 892 is also attached. A shaft portion 893 whose length can be adjusted is detachably connected, and a weight portion 894 whose weight can be adjusted is detachably connected to the shaft portion 893. According to this aspect, the adjustment ranges of the natural vibration frequency and the damping rate of the vehicle restraining jigs 12 and 82 are further expanded.

The cushioning material 62 is filled with a sponge or an air ball. Similar to the vehicle restraining jig 12, the support member 63 and the support column 64 have a tensile strength necessary for restraining the lateral force of the vehicle 1 such as a plate material or a steel pipe material using a material having excellent mechanical strength such as a steel plate. Made of material with compressive strength.

32, the support member 63 is horizontally supported by a horizontal support member 65 fixed to the column portion 64. As shown in FIG. On the other hand, the column portion 64 is erected by a standing support member 66 so that the position of the pedestal portion 67 arranged and fixed on the floor surface 9 can be adjusted in any of the vehicle width direction, the vehicle length direction, and the vehicle height direction of the vehicle 1. It is supported.

According to the vehicle restraint device 11 of the present embodiment described above, since the lateral shake suppression mechanism 61 is arranged, in addition to the effects of the first to eleventh embodiments, the vehicle generated during the test of the vehicle 1 using the chassis dynamometer. 1 lateral vibration (lateral force) can be suppressed. Thereby, movements other than the pitching and vertical movement of the vehicle 1 can be suppressed.

Incidentally, as a vehicle restraint device in a chassis dynamometer, for example, a vehicle fixing device disclosed in

Patent Documents

5 and 6 is known. In the vehicle fixing device of Patent Document 5, the vehicle fixing devices are arranged at corresponding positions at the four corners of the test vehicle. The vehicle fixing device of Patent Document 6 includes a vehicle stop bar that fixes the front and rear sides of the test vehicle, and a side presser that fixes the left and right sides of the vehicle.

However, the vehicle fixing devices of

Patent Documents

5 and 6 tend to suppress the vehicle pitching motion more than necessary because the front and rear and the left and right sides of the test vehicle are almost completely fixed. The vehicle behavior approximated to may not be reproduced.

On the other hand, the vehicle restraint device 11 of the present embodiment ensures the release of the vehicle pitching motion by including the vehicle restraint jig 12 of any of the first to eleventh embodiments and the lateral shake suppression mechanism 61. However, the lateral force of the vehicle 1 generated during the test of the vehicle 1 can be suppressed. Thereby, the vehicle behavior in which the vertical load approximates to the road can be realized more effectively.

Further, the lateral shake suppression mechanism 61 is disposed in a pair of left and right at the front wheel side and rear wheel side positions of the vehicle 1, so that the vehicle 1 is positioned near the left and right front fender portions and the left and right rear fender portions of the vehicle 1. Can be suppressed. Therefore, normally, it is possible to operate without interfering with the cooling fan discharge port of the vehicle 1 for cooling the engine installed in front of the vehicle 1. In addition, since it does not interfere with the door opening and closing of the vehicle 1 such as when getting on, the preparation time when the measuring device is mounted on the vehicle 1 can be shortened.

Furthermore, in the lateral vibration suppression mechanism 61, the cushioning material 62 is elastically contacted with the main body of the vehicle 1, so that it is possible to reduce the influence of hindering the pitching motion of the vehicle 1. Further, since the arrangement position of the buffer material 62 can be adjusted in the width direction of the vehicle 1 by the support member 63, the arrangement of the buffer material 62 can be arbitrarily set according to the vehicle width of the vehicle 1.

Since the support portion 64 can be arranged in any of the vehicle width direction, the vehicle length direction, and the vehicle height direction, the cushioning material 62 is arranged according to the vehicle width, vehicle length, and vehicle height of the vehicle 1. Can be set arbitrarily.
