Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1 and 2, fig. 1 is a schematic diagram of a spoke sensor according to the present invention; fig. 2 is a schematic view of the pin of fig. 1.
The invention provides a spoke sensor, which comprises an inner ring 1, an outer ring 2 and a measuring beam 3 arranged between the inner ring 1 and the outer ring 2, wherein a non-measuring beam 4 is further arranged between the inner ring 1 and the outer ring 2, an axial through hole 5 is formed in the non-measuring beam 4, the non-measuring beam 4 is disconnected at the through hole 5, a pin shaft 6 is arranged on the through hole 5, the pin shaft 6 and the through hole 5 can axially move relatively, two ends of the pin shaft 6 are respectively provided with a stop block 9, and the stop blocks 9 are used for limiting the maximum axial relative displacement between the pin shaft 6 and the through hole 5 so as to limit the maximum axial relative displacement between the disconnected ends of the non-measuring beam 4.
The non-measuring beam 4 may be disposed at an intermediate position between the axial widths of the inner ring 1 and the outer ring 2, and the axial width of the non-measuring beam 4 may be substantially the same as the axial width of the measuring beam 3, and of course, the axial width of the non-measuring beam 4 may be greater than or less than the width of the measuring beam 3.
The through hole 5 on the non-measuring beam 4 can be arranged at the position of the general center of the non-measuring beam 4, and the position of the non-measuring beam 4 disconnected at the through hole 5 can be arranged at the center of the through hole 5, so as to ensure the uniformity of stress at the two disconnected ends of the non-measuring beam 4.
To ensure that the pin 6 is axially movable relative to the through hole 5, the maximum diameter of the pin 6 should be smaller than the minimum diameter of the through hole 5, and the minimum diameter of the pin 6 should be larger than the maximum radial width of the gap broken at the through hole 5, so that the pin 6 is prevented from sliding out of the gap broken at the through hole 5.
The distance between the stops 9 at the two ends of the pin 6 determines the magnitude of the axial relative displacement of the two broken ends of the non-measuring beam 4, and the magnitude of the axial relative displacement of the two broken ends of the non-measuring beam 4 determines the maximum allowable axial deformation of the measuring beam 3.
Therefore, the two end stoppers 9 of the pin shaft 6 have the function of limiting the axial relative displacement of the two broken ends of the non-measuring beam 4, and further limiting the maximum deformation of the measuring beam 3 in the axial direction, so that the maximum displacement of the pin shaft 6 in the axial direction relative to the through hole 5 should be determined according to the maximum deformation of the measuring beam 3 in the axial direction, and then the distance between the two end stoppers 9 of the pin shaft 6 is determined according to the maximum displacement of the pin shaft 6 in the axial direction relative to the through hole 5. The determination of the maximum axial deformation that can be tolerated by the measuring beam 3 can be determined by means of finite element analysis.
When the spoke sensor is overloaded by axial stress, the stop block 9 contacts with the end face of the non-measuring beam 4 and prevents the two ends of the non-measuring beam 4 disconnected from generating relative displacement further axially, so that the end face of the stop block 9, which is close to the non-measuring beam 4, can be a plane, the end face of the corresponding non-measuring beam 4 can be a plane, and the end face of the non-measuring beam 4 is parallel to the end face of the stop block 9, which is close to the non-measuring beam 4, so as to ensure the uniformity of stress when the stop block 9 contacts with the end face of the non-measuring beam 4.
According to the spoke sensor provided by the invention, the non-measuring beam 4 is additionally arranged between the inner ring 1 and the outer ring 2, and when the measuring beam 3 is deformed due to axial force in the working process and the deformation is in a reasonable range, the non-measuring beam 4 is disconnected at the through hole, and the pin shaft 6 and the through hole 5 on the non-measuring beam 4 can move relatively in the axial direction, so that the two disconnected ends of the non-measuring beam 4 can move along with the inner ring 1 and the outer ring 2 under the action of the axial force, and the normal working of the spoke sensor is not influenced; when the axial force of the measuring beam 3 is overlarge and exceeds the measuring range of the spoke sensor, as the two end stop blocks 9 of the pin shaft 6 limit the maximum relative displacement of the pin shaft 6 and the through hole 5 in the axial direction, after the relative displacement of the two disconnected ends of the non-measuring beam 4 reaches the maximum displacement limited by the stop blocks 9, the relative displacement of the two disconnected ends of the non-measuring beam 4 is not increased any more, thereby preventing the further increase of the axial deformation of the measuring beam 3 and the axial deformation of the measuring beam 3 is not increased any more; therefore, the spoke sensor provided by the invention avoids the problem of failure of the spoke sensor caused by overload and over-deformation under the condition that the normal operation of the spoke sensor is not affected, and the over-deformation prevention devices are arranged in the spoke sensor, so that the universality of the use and the installation of the spoke sensor is greatly improved.
On the basis of the above embodiment, the problem that the spoke sensor may be subjected to circumferential torque during the installation process is considered, and if the circumferential torque is too large, the measurement beam 3 is excessively deformed, so that the spoke sensor fails is also considered. The pin shaft 6 installed in the through hole 5 can be a cylindrical pin, correspondingly, the through hole 5 can be a cylindrical hole, and the diameter of the cylindrical pin is larger than the radial width of a gap at the break of the through hole 5 so as to ensure that the cylindrical pin cannot slide out of the gap at the break of the through hole 5; the cylindrical pin and the cylindrical hole are in clearance fit, namely, a proper clearance is needed between the cylindrical pin and the cylindrical hole, so that the cylindrical pin can move relative to the cylindrical hole.
When the spoke sensor receives circumferential torque, the inner ring 1 and the outer ring 2 rotate relatively, so that the measuring beam 3 deforms circumferentially, at this time, on the non-measuring beam 4, gaps exist between the cylindrical pins and the cylindrical holes, so that the inner ring 1 and the outer ring 2 drive the two ends of the non-measuring beam 4 to break to generate circumferential equivalent displacement until the cylindrical pins are in contact with the inner wall of the cylindrical holes, the relative displacement of the two ends of the non-measuring beam 4 is prevented from further increasing, the maximum deformation of the measuring beam 3 in the circumferential direction is limited, and the problem that the spoke sensor fails due to overlarge circumferential torque is avoided.
Considering that the limitation of the cylindrical pin to the relative circumferential limit positions of the two disconnected ends of the non-measuring beam 4 should be within a reasonable range, the clearance between the cylindrical pin and the cylindrical hole should not be too large or too small, the spoke sensor is blocked due to too small clearance, the normal work of the spoke sensor is affected, and the cylindrical pin and the cylindrical hole can not be protected due to too large clearance fit, and the fit tolerance of the cylindrical pin and the cylindrical hole can be between IT5 level and IT7 level on the basis of the embodiment.
The positions of the non-measuring beams between the inner ring 1 and the outer ring 2 can be selected in various ways, on the basis of the above embodiment, the non-measuring beams 4 can be uniformly distributed between the adjacent measuring beams 3, in order to ensure the uniformity of the stress of the non-measuring beams 4, the non-measuring beams 4 can be arranged at the central position between the adjacent two measuring beams, and the plurality of non-measuring beams 4 can be distributed in a central symmetry manner about the axis of the inner ring.
On the basis of the above embodiment, considering that the non-measuring beam 4 is the main stress object when the spoke sensor is overloaded during the installation and use, the circumferential width of the non-measuring beam 4 may be greater than the circumferential width of the measuring beam 3, so as to improve the stress firmness of the non-measuring beam 4 during the operation.
On the basis of the embodiment, because the spoke sensor may receive circumferential torque in the installation process, the two broken ends of the non-measuring beam 4 generate circumferential relative displacement, namely generate relative rotation, so the sections of the two broken ends of the non-measuring beam 4 at the through hole 5 can be arc surfaces, and the axes of the arc surfaces can be coaxial with the axes of the inner ring 1. When the gap at the break of the through hole 5 is smaller, the arrangement of the arc surface does not influence the circumferential relative rotation of the two broken ends of the non-measuring beam 4.
The method of disconnecting the non-measuring beam 4 at the through hole 5 can cut the non-measuring beam 4 by a wire cutting machine, or can directly reserve a needed gap in the process of processing the non-measuring beam 4, namely, a section of non-measuring beam 4 is processed on the same radial direction of the outer ring 2 and the inner ring 1 of the spoke sensor respectively, and a proper gap is reserved between the two sections of non-measuring beams 4 on the outer ring 2 and the inner ring 1.
Referring to fig. 2, on the basis of any of the above embodiments, the stop blocks 9 at two ends of the pin shaft 6 may be provided in various manners, for example, the stop blocks 9 may be retaining rings 8 provided at two ends of the pin shaft 6, corresponding annular grooves 7 for installing the retaining rings 8 should be provided at two ends of the pin shaft 6, or other options may be provided, for example, the stop blocks may be positioning nuts, corresponding external threads should be provided at two ends of the pin shaft 6, and the distance between the positioning nuts at two ends of the pin shaft 6 needs to be limited.
On the basis of the embodiment, the retainer ring 8 can be an elastic retainer ring, and the retainer ring is convenient to obtain materials and simple to install.
In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.
