Since the rail comer 55 is freely movable on the rail 4, the vehicle restricting device 1 can be mounted on the wheel hub 91 of the vehicle 90 for a plurality of different types of wheel bases, Do.

8 is a schematic view for explaining an expanding function of the vehicle supporting member. The tread and tire outer diameter are different depending on the type of the vehicle 90. Since the vehicle restricting device 1 is close to the rail 4 in the case of the vehicle 90 having a relatively large outer diameter of the tread and the tire at the fixing of the vehicle restricting device 1, the trapezoidal right- The length of the vehicle support member 40 is shortened by adjusting the number of thread threads mating with the mating portion 44 at the same time in both directions with respect to the left screw 46 (Fig. 8 (a)).

Further, in the case of the vehicle 90 having a relatively large tire outer diameter and a relatively small tread, the vehicle restricting device 1 moves away from the rail 4 as compared with the case shown in Fig. 8 (a). For this reason, adjustment is made to reduce the number of threaded teeth that engage both the trapezoidal-shaped right screw 45 and the trapezoidal-shaped left screw 46 both in the same direction and at the same time with the mating portion 44, (Fig. 8 (b)).

Since the vehicle restricting device 1 is close to the rail 4 in the case of the vehicle 90 having a relatively large tread, the trapezoidal right screw 45 and the trapezoidal left screw 46 The length of the vehicle supporting member 40 is shortened by adjusting the number of threaded portions mating with the mating portion 44 at the same time in both directions and reducing the length of the vehicle supporting member 40 (Fig. 8 (c)).

In the case of the vehicle 90 having a relatively small outer diameter of the tread and the tire, the vehicle restricting device 1 moves away from the rail 4 as compared with the case shown in Fig. 8 (c). For this reason, adjustment is made to reduce the number of threaded teeth that engage both the trapezoidal-shaped right screw 45 and the trapezoidal-shaped left screw 46 both in the same direction and at the same time with the mating portion 44, (Fig. 8 (d)).

The operation and effect of the vehicle restraint apparatus 1 according to the present embodiment will be described. The vehicle restraint apparatus 1 includes a hub attachment portion 10 to be attached to and detached from a wheel hub 91 of a vehicle 90 and two attachment portions 10a and 10b to be coupled to the shaft 20 connected to the attachment hub portion 10. [ And a pair of vehicle support members 40 that are connected to the vehicle support member holding portion 30 and support the vehicle 90. The vehicle support member holding portion 30 is supported by the shaft bearings 25A, . The vehicle support member holding portion 30 includes an annular first support member 31 connected to the one first vehicle support member 41 of the pair of vehicle support members 40, And an annular second support member 32 connected to the second support member 32. The first support member 31 and the second support member 32 are rotatably supported by two shaft bearings 25A and 25B that are independently coupled to the shaft bearing engagement portion 22 of the shaft 20 And are integrally superimposed in a fixed state.

When the vehicle 90 placed on the roller 3 of the chassis dynamometer 2 experiences a sudden acceleration during the test, the inertial force of the vehicle 90, such as pitching, Is applied to the vehicle support member holding portion (30) of the vehicle restraint device (1) mounted on the wheel hub (91). 9, the axis X of the shaft 20 at which the first vehicle supporting member 41 and the second vehicle supporting member 42 intersect with each other is formed in the vehicle supporting member holding portion 30. In this case, The wheel hub 91 can be arranged to coincide with the rotation center of the wheel hub 91, so that no torque is generated in the vehicle support member holding portion 30 even when the external force is generated.

Therefore, even if a sudden acceleration is accompanied by the vehicle 90, the rotation of the vehicle support member holding portion 30 can be inhibited, so that the wheels of the vehicle 90 are moved forward and backward from the rollers 3 of the chassis dynamometer 2 (In the lateral direction in Fig. 7).

6 and 7, when viewed from the side of the vehicle 90, a pair of vehicle supporting members 40 (first and second vehicle supporting members 41 and 42) Are arranged in a substantially eight-letter shape centering on the wheel hub 91 and are provided to be inclined with respect to the rail 4 on the bottom of the pit, the vehicle 90 is supported by the pair of vehicle support members 40, (Lateral direction) (in the vertical direction in Fig. 6).

Furthermore, the vehicle restricting device 1 can be applied to evaluation tests such as lateral vibration (yawing) of the vehicle body and lateral abrasion of the wheel during corner driving as well as evaluation tests of wind force and accompanying vibration from the front of the vehicle Do.

Therefore, according to the vehicle restraint apparatus 1 of the present embodiment, the vehicle 90 placed on the rollers 3 of the chassis dynamometer 2 during the evaluation test is moved in the front-rear direction (the left-right direction in FIG. 6) (Fig. 6, vertical direction), and it is possible to reliably confine the transverse direction in the transverse direction (Fig. 6, vertical direction).

However, as shown in FIG. 10, when a sudden acceleration occurs during the test of the vehicle equipped with the vehicle restraint device according to the above-described conventional example, the external force F caused by the inertia force of the vehicle causes the vehicle- (130) is rotated about the hub attaching portion.

10, the first vehicle supporting member 141 and the second vehicle supporting member 142 are engaged with the axial center X of the wheel hub 91 at the rotational center of the wheel hub 91 , The torque is generated in the vehicle support member holding portion 130 when the external force F is generated.

When this rotation occurs, the first and second vehicle support members 141 and 142, which are connected to both ends (the first end C1 and the second end C2) on the longer radius side of the elliptical vehicle support member holding portion 130, There is a problem in that the vehicle body 142 moves in the forward and backward direction after the vehicle support member holding portion 130 is rotated about the axis X as a center.

In contrast, in the vehicle restraint apparatus 1 of the embodiment of the present invention, even when the above-described external force F acts on the vehicle support member holding portion 30, no torque is generated in the vehicle support member holding portion 30 The vehicle support member holding portion 30 can not rotate and the first vehicle supporting member 41 and the second vehicle supporting member 42 do not intersect with each other so that the vehicle 90 mounted on the chassis dynamometer 2 Can certainly be restrained.

The vehicle restricting device 1 according to the embodiment of the present invention is configured such that when the evaluation test is performed by placing the vehicle 90 on the rollers 3 of the chassis dynamometer 2, 90) can be reliably restrained, the safety of the evaluation test is further improved. In addition, since the structure of the vehicle restraint apparatus 1 of the embodiment of the present invention is simple and lightweight, the workability of the evaluation test is also improved.

While the embodiments of the present invention have been described, the present invention is not limited to the embodiments described above, but may be modified and changed without departing from the gist of the invention.

(1) For example, in order to correspond to a plurality of kinds of vehicles 90 having different outer diameters (hub outer diameter of the hub bolts) of the wheel hub 91 depending on the model of the vehicle, A plurality of types of hub attachment portions 10 are formed at the pitch outside diameters of the through holes 11 corresponding to the hub attachment portions 10 and the spline portions 21 of the shaft 20 connected to the plural hub attachment portions 10 It is freely exchangeable.

(2) In the present embodiment, the shaft bearings 25A and 25B are ball-and-shaft bearings, but the shaft bearings may be roller bearings or the like in addition to the present embodiment. In the two shaft bearings, And the outer ring may be relatively free from the inner ring.

(3) In the present embodiment, the number of hub bolts provided on one wheel hub 91 is five, but the number of hub bolts can correspond to the number of hub bolts of the actual vehicle to be subjected to the evaluation test will be.

As described above, according to the present invention, it is possible to reliably restrict the vehicle mounted on the chassis dynamometer in the front-rear direction and the width direction of the vehicle during the evaluation test.
