Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a restraining and mooring device for a test vehicle, and in particular, to a device for mooring a test vehicle securely and easily to a vehicle testing device, and also for lifting the test vehicle while it is moored. This invention relates to a restraining and mooring device for a test vehicle that is capable of improving the adjustment workability of the test vehicle while moored, and also allows the test vehicle to be easily adjusted and moved to the center of the vehicle testing device in the front, rear, left, and right directions. be.

<Prior art> Conventionally, in the case of vehicle testing equipment, which is one of the testing methods for vehicles such as automobiles and motorcycles, in order to conduct tests on the rotating drum of the vehicle testing equipment, the test vehicle is placed on the rotating drum. The vehicle had to be moored to the vehicle test equipment in order to prevent it from coming off the rails.

Therefore, generally, as shown in FIG. 9, mooring wires S such as ropes or wires are fixed to the front, rear, left, and right sides of the test vehicle A, and mooring wires S and mooring wires are provided at distances in the front, rear, left, and right of the test vehicle A. It was moored by being locked to member K.

Then, the wheels W of the test vehicle A are rotatably mounted on the rotating drum D of the vehicle testing device, and the wheels W
By rotating the test vehicle A on the rotating drum D, various tests were carried out by reproducing the actual running condition of the test vehicle A.

However, in such conventional methods,
Since the test vehicle A is moored by the mooring wire S, it is necessary to tie and loosen the mooring wire S during mooring, which not only makes the mooring work worse but also requires more attention. On the other hand, since the mooring wire S expands, contracts, or loosens, there were problems such as the possibility that the test vehicle A would come off the rotating drum D during the test.

For this reason, a method has conventionally been proposed in which the test vehicle A is moored to the locking member K using a rigid mooring member instead of the mooring wire S. Not only is it impossible to make adjustments, but it is also necessary to perform troublesome width-aligning work to move the test vehicle to the center of the test equipment, and furthermore, the test vehicle A is prone to pitching, rolling, bouncing, etc. Since motion was not possible, there was a problem in that it was not possible to reproduce the driving conditions of an actual vehicle.

<Problems to be solved by the invention> In view of these problems of the prior art, the main purpose of the present invention is to securely and easily moor the test vehicle, and to moor the test vehicle in the longitudinal and lateral directions. By enabling the test vehicle to perform movements such as pitching, rolling, and bouncing, and improving the reproducibility of the actual vehicle driving condition, and by making it possible to lift up the test vehicle while the test vehicle is moored. To provide a restraining and mooring device for a test vehicle, which improves adjustment workability, allows easy adjustment and movement of a test vehicle to the center of a vehicle testing device, and enables accurate vehicle testing.

<Means for Solving the Problems> According to the present invention, the wheels of the test vehicle are rotatably mounted on a rotating drum, and the wheels are rotated on the rotating drum to solve the problems. A vehicle testing device that performs various tests by reproducing the running conditions of a test vehicle, which includes a movable engagement part that is attached to the test vehicle, and a support that engages the movable engagement part in a vertically movable manner. a vertically movable engagement mechanism that engages the test vehicle in a vertically movable manner; a support frame that supports the column; and a support frame that supports the column and restrains the test vehicle from moving in the longitudinal direction. a vehicle longitudinal mooring section that is provided on each of the fixed shaft and the support shaft and that is capable of adjusting the longitudinal position of the test vehicle; a sliding tube to which the support column is fixed and which is slidably fitted onto the fixed shaft; a spring seat protruding from the sliding tube; and a spring seat protruding from the sliding tube. a left-right mooring spring that is resiliently mounted between the seat and the support frame and urges the support column approximately toward the center of the fixed shaft; an engaging moving part that engages with the support column and moves the support support in the left-right direction; and a left-right position adjustment body that adjusts the left-right position of the support support, and adjusts the left-right position of the vehicle. This is achieved by providing a restraining and mooring device for a test vehicle, characterized in that it is equipped with a lateral mooring mechanism section having a lateral direction adjustment section capable of adjusting the lateral direction.

<Function> As described above, according to the present invention, the test vehicle restraint mooring device including the longitudinal mooring mechanism, the lateral mooring mechanism, and the vertical movable engagement mechanism allows the vehicle to be restrained. Since the test vehicle is moored to the test equipment, it is not only possible to move it forward and backward, left and right, and up and down, but also to adjust its position in the forward and backward and left and right directions, improving the reproducibility of actual vehicle driving. Moreover, the workability of the vehicle test is also improved.

By the way, in this test vehicle restraint and mooring device, the test vehicle can be moored to the vehicle testing device in the following manner.

First, the support of the restraint and mooring device of one of the test vehicles (for example, located in front of the test vehicle) is tilted from a vertical state to a substantially horizontal state, so that the test vehicle can enter.

Next, the test vehicle is caused to pass over the restraint and mooring device of the one test vehicle and enter the vehicle testing device. Next, the test vehicle is lifted up using an autolift.

Furthermore, after sliding the support of the restraining and mooring device of the one test vehicle to bring the support into a substantially vertical state,
Tighten the lock nut to maintain the column in a generally vertical position.

Next, the columns of both restraint and mooring devices of the test vehicle (located at the front and rear of the test vehicle) are moved in the longitudinal direction to a position where they can be engaged with the engagement rollers attached to the test vehicle. Adjust the position forward and backward and left and right using the adjustment section and left and right position adjustment section.

Next, while the test vehicle is placed on the autolift, it is lifted down little by little, and the engagement rollers provided at the front and rear of the test vehicle are engaged with the pillars located at the front and rear of the test vehicle by the above operation. , the movable engagement portion and the support portion are engaged.

Furthermore, the test vehicle is lifted down using an autolift while the movable engagement portion and the support portion are still engaged, the vertical position is adjusted, and the test vehicle is mounted on the rotating drum.

Next, when the rotating drum is rotated with the test vehicle mounted on it, due to the unbalanced rotation of the rotating drum and the wheels mounted on the rotating drum, the sliding cylinder passes through the test vehicle, the engagement roller, and the support. Periodic vibrations are transmitted, and slight fluctuations in amplitude are applied to the fitting gap between the sliding tube and the fixed shaft at a period commensurate with the vibrations. In addition, the vibration is similarly transmitted to the movable tube that communicates with the sliding tube through the engagement between the engagement hole and the engagement pawl, and the vibration is transmitted to the movable tube that is in communication with the sliding tube through the engagement between the engagement hole and the engagement claw. A small amplitude vibration is also applied to the threaded gap between the threaded screw and the screw.

At this time, due to the strong elastic force of the left-right mooring spring, the movable tube engaged with the left-right mooring spring moves toward the center in the left-right direction while passively sliding against the fixed shaft. It moves and converges to its approximate center.

In this case, the rotating shaft generates a rotational force due to the movement of the movable cylinder as the sliding cylinder moves, and passively rotates against the rotational frictional force of the screw.

Further, the adjustment handle is automatically rotated in the opposite direction to the adjustment in the left and right direction by the adjustment gear meshed with the rotating gear.

Therefore, the test vehicle automatically moves toward the center of the support column in the left-right direction and converges to the approximate center of the support column via the support support fixed to the sliding tube and the engagement roller that engages with the support support. .

As described above, according to the present invention, since the vehicle lateral mooring section and the lateral position adjustment section are provided, the test vehicle can be moved to the center of the testing device without the troublesome work of width adjustment as in the past. This makes it easier and more reliable to center the test vehicle on the vehicle test equipment.

The screw 8 is preferably one with high transmission efficiency, that is, one with a friction coefficient as small as possible, such as a ball screw, a plastic sliding screw, or a polished screw.

Next, the operation of the above embodiment will be explained.

According to the test vehicle restraining and mooring device described above, the test vehicle 14 is moored in the longitudinal direction, and includes a longitudinal mooring mechanism section capable of mooring the longitudinal movement of the test vehicle 14 and adjusting the longitudinal position of the test vehicle 14; and a left-right mooring mechanism that can adjust the left-right position of the test vehicle 14;
Since the test vehicle 14 is provided with a vertically movable engagement mechanism portion that engages the test vehicle 14 in a vertically movable manner, the test vehicle 14 is engaged with the vehicle testing device in the following manner.

First, the lock nut 35 of the support of the restraint mooring device of the test vehicle placed in front of the test vehicle 14 is
After loosening the support cylinder 20 and the support rod 34, the support column 1 is tilted forward (in the direction of the solid line arrow) as shown in FIG. 1, so that the support column 1 is brought into a substantially horizontal state.

Next, by driving the electric motor 24 of the test vehicle restraint mooring device located behind the test vehicle 14, the moving screw rod 21 is driven and rotated, thereby rotationally moving the guide roller 19, and 1 in a direction away from the test vehicle 14 (backward in FIG. 1) to prevent the test vehicle 14 from colliding with the support column 1 when the test vehicle 14 approaches.

Next, the test vehicle 14 is allowed to enter from the front of the test vehicle restraint and mooring device placed in front of the test vehicle 14, and the test vehicle 14 is moved back and forth so that the test vehicle 14 is placed.

Furthermore, the test vehicle 14 is lifted up by an autolift 26 disposed approximately in the center of the vehicle testing apparatus until the bottom surface of the movable engagement part is higher than the top surface of the support column 1.

Next, the support tube 20 and support rod 34 of the restraint mooring device of the test vehicle placed in front of the test vehicle 14 will be explained.
After sliding the column 1 and tilting the column 1 backward (in the direction of the dashed arrow) as shown in FIG. hold.

Next, by driving the electric motor 24 of the test vehicle restraint and mooring device placed in front of the test vehicle 14, the moving threaded rod 21 is actuated to move the column 1 in the front and rear direction. The directional position is adjusted so that the support column 1 is in a position where it can be engaged with a movable engagement portion provided at the front of the test vehicle 14. Subsequently, by driving the electric motor 24 of the test vehicle restraint mooring device located behind the test vehicle 14, the moving screw rod 21 is moved in the same manner as described above.
is activated to move the strut 1 in the front-rear direction and adjust the longitudinal position of the strut 1, so that the strut 1 is in a position where it can be engaged with the movable engagement portion provided at the rear of the test vehicle 14. Do it like this.

Next, the handles 1 of the test vehicle restraint and mooring device located in front of the test vehicle 14 and the test vehicle restraint and mooring device located behind the test vehicle 14 are
1, the rotary shaft 9 is rotated via the rotary gear 7, and the movable tube 1 is rotated via the screw 8.
Slide 3. As a result, the support 1 is moved in the left-right direction through the engagement between the engagement claw 12 and the engagement hole 1a, and the lateral position of the support 1 is adjusted. The position is such that it can be engaged with each of the engagement rollers 17 provided at the front and rear. Next, the test vehicle 14 is lifted down little by little while being placed on the autolift 26, and the engagements provided at the front and rear of the test vehicle 14 are adjusted by adjusting the left and right positions and the front and back positions of the pillars 1. By engaging the rollers 17 with the struts 1 located at the front and rear of the test vehicle 14, the movable engagement portion and the struts 1 are engaged. Further, the test vehicle 14 is lifted down by the autolift 26 while the movable engagement portion and the support column 1 are kept engaged, and the test vehicle 14 is mounted on the rotating drum 25. Next, when the rotating drum 25 is rotated with the test vehicle 14 mounted thereon, due to rotational imbalance of the rotating drum 25 and the wheels W mounted on the rotating drum 25, the test vehicle 14, the engagement roller 17, Periodic vibrations are transmitted to the sliding tube 3 via the column 1, and slight fluctuations in amplitude are applied to the fitting gap between the sliding tube 3 and the fixed shaft 5 at a period commensurate with the vibration. In addition, the vibration is generated between the engagement hole 1a and the engagement claw 1.
The transmission is similarly transmitted to the movable tube 13 communicating with the sliding tube 3 through the engagement with the movable tube 13 and the rotating shaft 9.
A slight amplitude vibration (vibration in the left-right direction) is also applied to the threaded gap between the screw 8 screwed into the screw 8.

At this time, due to the strong elastic force of the left-right mooring spring 4, the sliding tube 3 is connected to the movable tube 13 which is in communication with the sliding tube 3 through the engagement between the engagement hole 1a and the engagement claw 12.
While passively sliding against the fixed shaft 5, the fixed shaft moves toward the center in the left-right direction of the fixed shaft 5 until the elastic force of the left-right mooring spring 4 is balanced. It converges to approximately the center of 5.

In this case, the rotating shaft 9 generates a rotational force due to the movement of the movable cylinder 13 accompanying the movement of the sliding cylinder 3, and the screw 8
passively rotates against the rotational frictional force of Also,
The adjustment gear 10 meshed with the rotating gear 7 automatically rotates the adjustment handle 11 in the opposite direction to that during the horizontal adjustment.

As a result, the test vehicle 14 is automatically moved in the left and right direction of the column 1 via the vehicle engagement column 1 fixed to the sliding tube 3 and the engagement roller 17 that engages with the vehicle engagement column 1. It moves towards the center of and converges to the approximate center.

This action is caused by the restoring force of the left-right moving mooring spring 4.
Due to the rotational frictional force between the screw 8 and the bearings 29 and 31, the sliding frictional force between the bearing 31 and the rotating shaft 9, and the vibrations generated from the rotation of the rotating drum D and the rotation of the wheels W of the test vehicle 14, the sliding tube This is caused by overcoming the static and dynamic frictional forces that alternately occur on the sliding surface between 3 and the fixed shaft 5, and as a result, the vehicle engagement strut 1 passively converges to the center of the device.

The key to this effect is that the greater the restoring force of the left-right mooring spring 4 is, the better; however, from a practical standpoint, the restoring force of the left-right mooring spring 4 must be within the range of practical operating force and operability of the adjustment handle 11. The point is that the rotational and sliding friction forces of each part are suppressed within the range where the restoring force can effectively function.

By the way, periodic vibrations are transmitted to the sliding tube 3 due to rotational imbalance of the wheel W, and the sliding tube 3 converges to approximately the center of the fixed shaft 5 due to the strong elastic force of the left-right mooring spring 4. However, this rotational imbalance of the wheel W occurs as follows.

One of them is the variation in tire radius that occurs during manufacturing, and when the test vehicle A contacts the rotating drum D.
By causing the test vehicle A to move vertically and tilt the test vehicle A in the left and right direction, the test vehicle A is caused to move in the left and right direction. This will give vibration (vibration in the left and right direction).

The second problem is the variation in tire thickness that occurs during manufacturing, which causes mass imbalance, which causes variation in the centrifugal force due to the rotation of the wheel W.
A device that causes the test vehicle A to move vertically when it comes into contact with the rotating drum D, and also causes the test vehicle A to tilt in the left-right direction, thereby causing the test vehicle A to move in the left-right direction in the same manner as above. Therefore, periodic vibration (vibration in the left-right direction) is applied to the sliding tube 3 via the support 1.

Therefore, conventionally, it is difficult to align the center of the test vehicle 14 with the center of the rotating drum 25 and mount the test vehicle 14 on the rotating drum 25.
A large amount of man-hours was spent on aligning the width of the vehicle many times, and the test vehicle was restrained and moored after being aligned with the center, and the test was conducted as it was. However, according to the above example, the test vehicle 14
When the test vehicle 14 is mounted on the rotating drum 25 and moored with the longitudinal center of the rotating drum 25 approximately aligned with the longitudinal center of the rotating drum 25, and the rotating drum 25 is rotated, Due to the vibration transmitted to the sliding tube 3 via the test vehicle 14, the engagement roller 17, and the support column 1, and the strong restoring force of the left-right mooring spring 4, the sliding tube 3 is moved along with the movable tube 13 to be engaged. while automatically moving to the center point of the support frame where the elastic forces of the left and right mooring springs 4 on both sides are balanced.
This has the remarkable effect of making it simple and easy to align the lateral center of the test vehicle 14 with the lateral center of the rotating drum 25.

Furthermore, by engaging the support column 1 with the movable engagement portion, it is possible to move and adjust the test vehicle 14 in the longitudinal and horizontal directions while the test vehicle 14 is moored, and the test vehicle 14 can be moved up and down. Since the test vehicle 14 can be moved arbitrarily in any direction, the test vehicle 14 in the vehicle test with the test vehicle 14 moored
pitching, rolling, and bouncing, making it possible to perform accurate vehicle tests with improved reproducibility of actual vehicle driving conditions.

In addition, since the test vehicle 14 can be moved vertically as desired while it remains moored, it is possible to lift it up using an autolift or the like, and it is possible to The test vehicle can be inspected, maintained, parts replaced, adjusted, etc., and adjustments made during the test are easy.

In the above embodiment, there are two types of supports that support the column 1 in the longitudinal direction and constitute the vehicle longitudinal mooring section together with the support frame, one of which is the following: , is a support that supports the column 1 so as to be tiltable in the longitudinal direction, and is provided in the test vehicle restraint mooring device that moores the front part of the test vehicle 14; test vehicle 1
The test vehicle's restraint mooring device moored the rear of the vehicle.

By the way, the present invention is not limited to the above-mentioned embodiment, and the support body that supports the column 1 so as to be tiltable in the longitudinal direction is attached to the restraining and mooring device of the test vehicle that moores both the front and rear parts of the test vehicle 14, respectively. It goes without saying that the test vehicle 14 may be provided with the test vehicle 14 not only from the front as in the above embodiment, but also from the rear, which has the effect of making vehicle testing easier.

Further, in the above embodiment, the guide roller 19
is formed to move in the longitudinal direction on the base of the vehicle testing device, but the present invention is not limited to the above-mentioned embodiment. For example, by providing a rail or the like to guide the movement of the guide roller 19, It is possible to restrict the movement so that it only moves in the front and rear directions.

Further, in the above embodiment, the restraining and mooring devices for the test vehicle are provided at the front and rear of the test vehicle 14, but the present invention is not limited to this.
4 can be provided only on either the front or rear part, which has the advantage of reducing costs.

<Effects of the invention> As described above, according to the invention, in a vehicle testing device that performs various tests by rotatably mounting the wheels of a test vehicle on a rotating drum, the front-back mooring mechanism and the left-right mooring Since the test vehicle was moored to the vehicle testing device using a test vehicle restraint mooring device that includes a mechanism section and a vertically movable engagement mechanism section, the test vehicle was moored in the longitudinal, horizontal, and vertical directions. Not only is it possible to move the test vehicle, but it is also possible to adjust the position of the test vehicle in the front, rear, left and right directions, and it is therefore possible to easily adjust and move the test vehicle to the center of the vehicle test equipment in the front, rear, left and right directions. .

Furthermore, by using a mechanism that allows the vehicle to be moved arbitrarily in the vertical direction during the test, the reproducibility of actual vehicle driving is improved, and the workability of the test vehicle is also improved.

In addition, the test vehicle can be moved vertically as desired while the test vehicle is engaged, and it can be lifted up using an autolift, etc., so the test vehicle can be moved while the test vehicle is engaged. We can inspect, maintain, replace parts, adjust, etc.
Adjustment work during the test becomes easier.

Furthermore, while the test vehicle is moored, it is possible to move and adjust the test vehicle in the longitudinal and horizontal directions, and the test vehicle can be moved arbitrarily in the vertical direction. This enables pitching, rolling, and bouncing of the test vehicle during testing, allowing for accurate vehicle testing with improved reproducibility of actual vehicle driving conditions.

In addition, the test vehicle restraint and mooring device of the present invention can be configured as the present invention by using the vehicle testing equipment currently in use without modifying the conventional vehicle testing equipment. This has the great effect of making running costs extremely low.
