[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a device for detecting the strike angle of running wheels in a vehicle. is the strike angle of the running wheels that are steered in conjunction with the operation of the steering wheel, It is linked to the operation of the relevant steering wheel so that it can be detected on the driver's seat side. This invention relates to a device for detecting the direction and angle of running wheels in a vehicle.

0002

[Conventional technology]

In vehicles, this is caused by the driver operating the steering wheel. The general method is to control and steer the running wheels in a desired direction and, ultimately, at a desired angle. Traditionally, this was done by learning how to operate the steering wheel while driving. Therefore, we try to understand the strike angle of this type of running wheel empirically.

0003

[Problem that the idea aims to solve]

However, on the other hand, the driver may not be skilled enough to operate the steering wheel. or when driving a vehicle in which you are unfamiliar with steering wheel operation. , it is necessary to check the running angle of the running wheels at the current moment or at the time of steering from the driver's seat. This may cause problems. In other words, for example, if a vehicle is parked in a garage while the running wheels are kept at a strike angle, In such cases, when a vehicle leaves the garage, the strike angle of the running wheels If the vehicle is parked in a narrow parking area with This corresponds to the start of a vehicle from of the steering wheel without considering the strike angle of the wheels. Performing unnecessary operations and suddenly starting the vehicle is due to neglecting to check the direction in which the vehicle is starting. This means that accidents are likely to occur and are extremely dangerous.

0004 This idea was made to solve these conventional problems. The target is a vehicle that is steered in conjunction with the operation of the steering wheel. A running vehicle in this type of vehicle in which the strike angle of the wheels can be detected from the driver's seat side. An object of the present invention is to provide a wheel strike angle detection device.

[0005]

[Means to solve the problem]

In order to achieve the above object, the strike angle of the running wheels in the vehicle according to this invention is The degree detection device detects when the vehicle is moving in conjunction with the operation of the steering wheel. The strike angle of the wheels, in other words, the inclination of the running wheels with respect to the vehicle's straight running axis. The steering wheel is used as a means to detect the angle (hereinafter simply referred to as strike angle) on the driver's seat side. The slope set on the steering wheel to make driving easier, and the steering wheel Utilizes the independent constant directivity of the operating weight, which is swingably installed on the ring wheel. The running speed is determined by the differential amount of the actuating weight in response to the steering operation of the steering wheel. It is designed to detect the running direction angle of the running wheels.

[0006] In other words, this invention addresses the requirements for the steering wheel that controls the vehicle's direction.

A running vehicle characterized in that it is configured to include at least an indicator mechanism section 41. This is a running direction angle detection device for running wheels.

[0007]

[Effect]

Therefore, in the running wheel steering angle detection device of this invention, the steering wheel The corresponding movement is caused by the rotation or movement of the case body 11 accompanying the steering operation.

You get it.

[0008]

【Example】

Below is an example of the device for detecting the strike angle of a running wheel in a vehicle according to this invention. This will be explained in detail with reference to FIGS. 1 to 6.

[0009] Figure 1 shows the detection of the running direction and angle of the running wheels in a vehicle to which the first embodiment of this invention is applied. An exploded perspective view showing the configuration of the device, Figure 2 shows the assembled state of the strike angle detection device. 3 and 4 are cross-sectional views of the main parts shown, and FIGS. 3 and 4 are the strike angle detection device assembled as above. This corresponds to the case where the steering wheel is rotated once and twice when the FIG. 3 is an explanatory diagram schematically showing how the strike angle of the running wheels is detected.

0010 In the device configuration shown in FIGS. 1 and 2, the running wheels according to the first embodiment are The strike angle detection device is a necessary part of the steering wheel (not shown) in the vehicle. For example, the axis of rotation of the steering wheel coincides with, or almost coincides with, the axis of rotation of the steering wheel. or on a surface other than the axis of rotation of the operation. The installation part is on the operating rotation axis in response to the steering operation of the steering wheel. If the installed part is not on the operating rotation axis, it will be moved. The main body part 11 is pivotally supported within the case main body part 11 so as to be freely swingable, and the above-mentioned Rotation associated with steering operation or free rocking following movement of the steering wheel an actuating weight 22, and an instruction display board 23 integrated with this actuating weight 22; An actuation mechanism section 21 having The gear shift is linked to the rocking motion and changes the running direction angle amount of the running wheels associated with the steering operation. An interlocking mechanism section 31 that transmits transmission based on the ratio, and an interlocking mechanism section 31 that is operated by the interlocking mechanism section 31 and An instruction display that indicates the strike angle of the running wheels using a pointer 42 on the instruction display board 23. It is composed of a mechanism section 41, and these sections function in conjunction with each other.

[0011] Therefore, the case main body 11 can accommodate and operate the mechanisms described above. A housing case 12 formed in a bottomed cylindrical shape with a space of A transparent synthetic resin plate, etc. that is fixed to the surface opening side of the base 12 to seal and close the inside. The bottom of the housing case 12 and the inside of the window plate 13 are Attached to the core are mounting holes for mounting both ends of the first shaft 14 as the main shaft. Holes 12a and 13a are drilled.

0012 In the case of this first embodiment, the first shaft 14 extends from the base end side to the distal end side. A relatively small-diameter proximal shaft portion 14a having a mounting screw formed at the proximal end, and a proximal side step. A support shaft portion 14c whose diameter is slightly increased through a portion 14b, and a support shaft portion 14c which has a slightly larger diameter through a support stepped portion 14d. The diameter is made slightly smaller through the intermediate shaft portion 14e having a larger diameter and the intermediate step portion 14f. The diameter is further reduced through the spline shaft portion 14g and the tip side stepped portion 14h, and the diameter is further reduced to the tip portion. The first shaft 14 has a distal end shaft portion 14i in which a mounting screw is formed. On the proximal side, a receiving collar 15a is inserted into the proximal step portion 14b from the inside of the housing case 12. After inserting a spring washer 16 with a relatively high elastic force through the base end shaft portion. 14a into the mounting hole 12a, and insert the flat washer 17a from the outside back side. It is installed with the locking nut 18 in the state where the The tip side stepped portion 14f receives the tip shaft portion 14g from the inside of the window plate 13 into the mounting hole 12b. Insert it through the guard flange 15b until it reaches the end, and then insert a flat washer from the outside surface side. 17b and an adjustment knob 19 which also serves as a locking nut. In addition, in the figure, the reference numeral 15c is a receiving flange interposed in the intermediate step portion 14d.

[0013] Therefore, when installed in such a state, this first shaft 14 14b and the bottom surface of the housing case 12. Due to the pressure, the tip side step portion 14h is constantly abutted against the inner surface of the window plate 13. Therefore, under normal conditions, this is integrated into the housing case 12 and eventually into the case body 11. It will be held fixedly, and if necessary, it can be adjusted externally. 19 by rotating against the abutment force, the step is rotated as described later. Zero point adjustment at the time of attaching the case body 11 to the ring wheel, i.e. In other words, it is possible to finely adjust the mounting angle position of the first shaft 14 with respect to the case body 11. It will become.

[0014] Here, the case main body 11 has a well-known steering wheel as described above. The required part of the wheel, for example, coincides with the operational rotation axis of the steering wheel, or to surfaces that are approximately coincident, or that are not on the axis of rotation of the operation. Although it is selectively installed as an accessory and works integrally with the steering wheel, If this is on the operating rotation axis of the former, the installation part is the steering wheel. With the steering operation, that is, the rotation operation, the housing case 12 itself is rotated by the operation. They will be rotated coincidentally or almost coincidentally on the axis, and this will also cause the latter If it is not on the operating rotation axis, the housing case will move as the steering wheel rotates. The base 12 itself moves on the circular locus of rotation of the installation part centered on the operating rotation axis. It will be.

[0015] Therefore, as will be described later, the detection of the strike angle of the running wheels through the operation of each of the mechanisms described above When considering from the point of view of instructions, the operating rotation axis of the steering wheel in the former case If you select an installation part that matches or almost matches the line, the housing case 12 In other words, the steering wheel itself does not substantially move from the installation position, in other words, the steering wheel does not move at first glance. It is possible to read the required strike angle indication even if it is not related to wheel steering operation. In addition, if there is a part installed other than on the operating rotation axis of the latter steering wheel, If you select , the housing case 12 will be operated together with the steering wheel operation. While the device itself is being moved, it will also read the strike angle instructions, and this The actions and effects brought about by each installation mode are explained from various viewpoints. Although both have advantages and disadvantages, it is usually preferable to select the former installation location. I can say that.

[0016] Further, the actuation mechanism section 21 is fixedly held within the case main body section 11. The needle bearing 24 is located on the axis of the support shaft portion 14c of the first shaft 14 The operating weight 22 is supported by a pivot so that it can freely swing as smoothly as possible with the intervention of The operating weight 22 has a lower half side with the pivot part as the border. The hollow housing part 22a has a semi-circular arc shape and serves as a weight, and the upper half side is the rear part. The instruction display board 23 is made into a semicircular arc shape with only half of the part, and the front of the instruction display board 23 is The display shows a base that is located in the vertical direction where the weight action works and corresponds to the axis of the vehicle in the straight direction. A directrix 23a is displayed.

[0017] The hollow housing portion 22a is provided with a position portion that does not inhibit the weight action. In other words, it is located at a position corresponding to the extension line of the reference line 23a, and serves as an intermediate axis. The second shaft 25 of is fixed.

[0018] Therefore, the operating weight 22, which is pivotally supported within the case body 11, In this case, the rotation of the case body 11 itself due to the steering operation of the steering wheel, Or, in relation to movement, it can be used independently to maintain the vertical direction in which the weight action always takes place. It is free-swinging, and in other words, as a result, the operating weight 2 2 automatically follows the rotation or movement of the steering wheel. Therefore, the rotation between the case body 11 and In other words, the amount of movement, and even the amount of steering of the steering wheel (direction relative to the running wheels) A differential amount corresponding to the angle amount) is generated, and the differential amount is displayed on the display surface of the instruction display board 23. The reference line 23a, which has been In this case, the steering angle of the vehicle is always independently independent of the amount of steering angle caused by the steering of the vehicle. A weight 22 for operating the case body 11 is oriented in the straight direction. The differential amount and the orientation direction of the reference line 23a on the surface of the instruction display board 23 will be described later. This plays an important role in detecting the strike angle of the running wheels.

[0019] Further, the interlocking mechanism section 31 is fixedly held within the case body section 11. The first shaft is engaged with the spline shaft portion 14g of the first shaft 14 and is integrally held fixed. The first gear 32 of the first stage and the hollow housing part 22a of the operating mechanism part 21 are The second gear 32 is rotatably loosely fitted onto the second shaft 25 and meshed with the first gear 32. The second gear 33 of the second stage is integrated with the second gear 33, and the second gear 33 of the second stage is The third gear 34 of the third stage is rotatably held on the shaft 25 with a loose fit, and the first shaft 1 4, and is rotatably loosely fitted onto the intermediate shaft portion 14e and meshed with the third gear 34. It has a series of gear trains each with a fourth gear 35 in the fourth stage (final stage). and each of these first to fourth gears 32, 33, 34, and 35 Regarding the mutual tooth number ratio, The amount of strike angle (generally, one rotation of the steering wheel in each direction to the left and right is Approximately 30 degrees to the left and right of the running wheels relative to the vehicle's straight axis The gear ratio is set to correspond to Ru.

[0020] Furthermore, the instruction display mechanism section 41 is substantially the same as that in the interlocking mechanism section 31. It consists of a pointer 42 that is integrally fixed and held to the fourth gear 35 of the final stage. Regarding this guideline 42, when the steering wheel is not steered, that is, when the steering wheel is not steered, In other words, when the running angle of the running wheels matches the axis of the vehicle in the straight direction, the front Extended to overlap the reference line 23a on the instruction display board 23 surface of the operating mechanism section 21. It has become so.

[0021] Therefore, each of the first to fourth gears 32, 33, which are set to such a tooth number ratio, An interlocking mechanism section 31 using a series of gear trains 34 and 35, and an operating mechanism section 2 An instruction display mechanism section 41 using a pointer 42 that overlaps and extends over the reference line 23a of 1. In this case, the housing case of the case main body part 11 is The shaft 12 itself, and the first shaft 14 fixedly held within the housing case 12, When rotated or moved, the operating mechanism follows this rotation or movement. Due to the free rocking of the actuating weight 22 at 21, the hollow housing portion of the actuating weight 22 is The second shaft 25 is fixed within the second shaft 22a, and the second shaft 25 is rotatably fitted loosely onto the second shaft 25. The held second gear 33 moves around the first gear 32 fixedly held on the first shaft 14. The third tooth which is integrated with this second gear 33 rotates on its own axis due to the planetary motion. The rotation obtained by the rotation is freely rotated on the first shaft 14 by the wheel 34. The fitted and held fourth gear 35 is rotated at a predetermined rotation ratio, that is, a gear ratio, and this The pointer 42 integrated with the fourth gear 35 is operated cooperatively, and as a result, the The amount of differential described in , that is, the direction of travel is activated in response to the amount of steering of the steering wheel. Only the angle corresponding to the strike angle amount of the running wheels is set based on the guideline 42. In this way, the amount of strike angle of the running wheels is adjusted as expected. can be detected and displayed on the instruction display board 23, and this display state can be maintained in good condition. It is. In other words, when the steering wheel is rotated one turn to the right, as shown in Figure 3, Move the pointer 42 approximately 30 degrees to the right with respect to the reference line 23a so that 4, and similarly rotated twice to the right, as shown in Figure 4. , move the pointer 42 roughly to the right by an amount equivalent to 60 degrees with respect to the reference line 23a. The driver can control the running angle of the running wheels at the current moment or at the time of steering. This can be easily confirmed on a device attached to the surface of the steering wheel. It is possible to do this.

[0022] Next, FIG. 5 shows the strike angle of the running wheels in a vehicle to which the second embodiment of this invention is applied. Figure 6 is an exploded perspective view showing the configuration of the angle detection device, and Figure 6 shows the above strike angle detection device assembled. FIG. 3 is a cross-sectional configuration diagram schematically showing the state.

[0023] In the configuration of the second embodiment, in the case of the configuration of the first embodiment, the hollow casing of the actuation mechanism section 21 is The interlocking mechanism section 31 and the instruction display mechanism section 41 disposed inside the body section 22a are disposed outside. This is just an example of how the The same functions and effects can be obtained.

[0024]

It is attached to the required part of the steering wheel to handle steering operations. In addition to providing a case body portion 11 that rotates or moves, the case body portion 11, the steering wheel rotates or moves freely following the movement of the steering wheel. The actuating weight 22 is pivotally supported so as to be able to swing, and is integrated with the actuating weight 22. The operating mechanism section 21 is provided with an instruction display board 22a arranged in the form of a Linked to the rocking movement of the weight 22, the running angle of the running wheels associated with the steering operation is determined. An interlocking mechanism section 31 that transmits transmission at a gear ratio of Then, a finger indicating the strike angle of the running wheels using the pointer 42 is displayed on the instruction display board 22a. Since the display mechanism section 41 is provided, it is possible to For operating the operating mechanism section 21 that follows the movement by rotating or moving. In order to allow the weight 22 to swing freely, there is a control unit between the case body 11 and the operating weight 22. This will generate a differential corresponding to the amount of rudder, and the amount of differential obtained in this way is Corresponds to the strike angle amount of the running wheels associated with the steering operation given to the interlocking mechanism section 31 The gear ratio is transmitted to the pointer 42 of the instruction display mechanism 41, and this pointer is actuated. The running direction of the running wheels corresponds to the steering amount of the steering wheel. Accurately detects the amount of angle and uses this detected angle as an indicator integrated into the operating weight 22. The pointer can be displayed on the display board 22a, and as a result, the It is extremely easy to check the running angle of the running wheels at the current moment or at the time of steering from the driver's seat. I can recognize it.
