Abstract

PURPOSE:To eliminate distortion present in the abutment surfaces of a wheel and a contact by joining the contact to an angle detecting arm via a regulation means which is allowed a degree of freedom in a plane in which it abuts to the side face of the wheel, and allowing the means some degree of freedom only when it abuts to the wheel. CONSTITUTION:A wheel is clamped and a roller 13 is made to abut to the abutment part M of the side face of the wheel. As the fixed state of the middle point of the wheel is monitored, the eccentricity of the wheel is corrected. A regulation means 12 is allowed some degree of freedom and the roller 13 to be disposed in a sensor arm 11 is held in a movable state via the means 12, and then the wheel is rotated by one turn. The roller 13 is driven by the wheel, rolling its roller main body 131 in the direction perpendicular to the direction N of its roller axis. In a state in which distortion that causes upward movement of the roller 13 may occur, for example, the roller 13 escapes upward and shifts to its U-position. Therefore, when the roller 13 is fixed, unremovable distortion is absored within the amount of movement of the roller 13, so preventing distortion of the abutment surfaces. Thereafter, the wheel is stopped and is clamped on both sides.

By inspecting and measuring the corners and the like and adjusting the inclinations to be suitable for each, maintenance is performed so that the running performance of the vehicle becomes suitable. For the wheel inspection, the wheel is rotatably mounted on a pair of supporting rollers, and both sides of the wheel are clamped by a wheel clamp device via a plurality of contacts to thereby adjust the inclination degree. There is inspection technology. As the contactor used for the clamp, there are a fixed cylindrical body which does not roll itself and a roller type which can make rolling contact. Among these conventional techniques, there are Japanese Patent Application No. 64-72001 for the angle detection device and Japanese Patent Application Nos. 64-72027 and 64-72028 for the wheel clamp device by the applicant of the present application.

車両の重要な性能評価に使われる。Further, regarding the camber angle, the contactor provided on the angle detecting arm provided on one side of the wheel is brought into contact with the upper and lower sides of the side surface of the wheel, and at that time, the contactor is interposed. The angle is detected by an angle detector pivotally supported by the angle detecting arm. A vehicle equipped with wheels having an adjusted camber angle can show proper running performance in which the steering wheel can be positioned appropriately and the steering operation force is reduced during running. As described above, since the toe angle and the camber angle have an inseparable relationship with each other and contribute to the running performance of the vehicle, they are inspected and measured by the same wheel inspection device. Even if there is little difference or unbalanced adjustment, these inclinations have results in their running performance,
Used for important performance evaluation of vehicles.

ものである。Conventionally, the inclination angles of the toe angle and the camber angle are measured by allowing the vehicle to run on the wheel inspection device and placing the wheels on the rotatably juxtaposed support rollers. To do. Then, after the inspection reference line for wheel measurement is established, the clamp device is operated to bring the plurality of contacts into contact with the side surfaces on both sides of the wheel so that the wheel that has been freely rotated in advance is supported by the support roller. The required inclination was inspected and measured after the wheel was rotated at least once by the driving operation. In the one-rotation operation, in the initial state in which the vehicle is self-propelled and placed on the support roller,
The eccentricity generated in the support roller and the wheel due to the self-propelling of the vehicle and the distortion generated in the contact surface between the wheel and the contact may remain, so the distortion or the like is removed. This operation is performed for the purpose of obtaining an appropriate wheel measurement state.

認されて精密な傾斜度測定を困難にしている。However, at least the contact element that can be brought into contact with the wheel is fixed to the angle detecting arm that is connected to the clamp means, and is pressed against the wheel in that state. Therefore, it is impossible to remove the strain that can be eliminated by slipping the contactor. Specifically, due to unevenness such as engraved characters engraved on the surface and rubber, the wheel side surface and the contact are distorted on the contact surface by the applied clamping force and the generated frictional force. (Hysteresis) occurs,
The fact that a certain proper measurement state cannot be obtained has been a problem in measuring the gradient. Therefore, the contact portion of the contactor is replaced with a roller capable of rolling contact from the cylindrical body, and the degree of freedom due to the rolling is given to the left and right movements, so that there is no deviation in the inclination measurement due to the distortion. A roller clamp device has been developed in which the size is improved within about 10 minutes at the camber angle. However, even in this device, the degree of freedom of movement in only one direction within the contact plane is given, and therefore, The effect of strain cannot be removed sufficiently, and residual strain is still confirmed, making precise tilt measurement difficult.

い。According to such a technical means, the contactor attached to the angle detecting arm and abutting against the side surface of the wheel as in the prior art has only freedom of movement in the roller rolling direction. However, the inspection is not performed while the contact surface with the wheel is distorted, and the distortion generated in the contact surface is not limited to one direction in which the roller rolls, but also in a plurality of directions in the contact plane. The degree of freedom that makes it easy to move is provided, and in the process of one rotation operation of the wheel, the contact can eliminate the distortion, and as a result, the arm having the contact, It is possible to perform the roller clamp of the wheel that creates a measurement state in which an appropriate inclination without transmission of distortion can be transmitted to the angle detector. The contact means is in a movable state in a plane at the time of contact with the side surface of the wheel, but the contact itself is interposed between the arm and the wheel through the restriction means to fix its position. The contact is not lowered by its own weight.

すことが出来る。Next, the operation of the present invention will be described mainly with reference to FIG.
Will be explained. The wheel clamp device is operated to clamp both sides of the wheel 1, and after the roller 13 is brought into contact with the contact portion M on the side surface of the wheel 1, the fixed state of the middle point of the wheel 1 is monitored. However, in order to correct the eccentricity of the wheel 1 by the monitoring and to release the strain generated in the contact portion M to the roller 13 side having the freedom of movement in the contact plane, The degree of freedom of the regulating means 12 is set to an allowable state, and the sensor arm 1 is passed through the regulating means 12.
After making the roller 13 arranged in No. 1 movable, the wheel 1 is operated once. After the one-rotation operation, the slider 13 is movable along the roller rolling direction and the roller axis direction by the in-plane movable state, and the roller 13 is rotated. Under the condition that the wheel body 1 is driven in the course of the operation to roll the roller body 131 orthogonally to the roller axis direction and the strain accompanied by the movement of the roller 13 is generated on the upper side. Then, the roller 13 escapes upward and moves to the position of the roller 13U, and if the distortion occurs downward, the roller 13D
When the roller 13 is fixed, the irreversible strain is absorbed in the moving amount by moving in the direction, so that the contact surface is not distorted, and the wheel thereafter. There is no concern that the distortion will be mixed in the detection angle obtained when 1 is stopped and both sides thereof are clamped. The free movement amount in the contact plane at the time of measuring the camber angle in the roller axis direction is usually a unit of several millimeters, but the movement amount that can be set in advance in the contact roller is: A unit of several tens of millimeters, preferably around 40 millimeters is set. Further, if the inspection measurement without the distortion can be performed at the time of the camber angle measurement, it can be considered that the measurement error due to the distortion is not mixed in the other toe angle and the caster angle measurement.

めて大である。As described above, according to the present invention, the arm for detecting the angle of the wheel is provided with the degree of freedom through the restricting means to the roller directly related to the detection of the inclination of the wheel. Since the degree of freedom is allowed only when the wheels contact each other, the detection operation of the angle detector that is inseparably linked to the wheel clamp device is absorbed by absorbing the strain generated on the contact surface with the wheel during the wheel inspection. In addition, errors that occur when distortion occurs can create a state that does not mix in, make it possible to detect in an appropriate measurement state, and as a result, present a technology that can improve maintenance work, etc. It is possible to provide a wheel clamp device which has a remarkable effect and is reliable for the first time in the present invention and which can perform a wheel inspection, and its practical value is extremely large.
