Description
Technical field
The utility model relates to one and turns to detecting device and self-travel type high-altitude operation platform thereof, belongs to field of mechanical technique.
Background technology
Steering swivel system is the important component part of vehicle chassis, the quality of steering swivel system performance directly has influence on the safety of vehicle traveling, operational stability, it is for guaranteeing that the driving safety of vehicle plays important effect, according to Vehicular turn principle: vehicle be allowed to turn to smoothly, each wheel must by different circular motion, due to take turns in car the circle radius of process less, therefore its steering angle is larger than foreign steamer, if draw a straight line perpendicular to them to each wheel, so the intersection point of line is the center-point turned to.Basic concept by Ackerman principle: vehicle is in traveling (straight-line travelling or turning driving) process, and the path of motion of each wheel must meet its proper motion track completely, thus ensure to be in pure rolling between tire and ground and without sliding phenomenon.
Current turns to detecting device as shown in Figure 1, on wheel steering shaft 6 upper surface, be normally drilled with a circular hole slightly larger than rotary angle transmitter 3 shaft diameter, sidewall is drilled with a threaded securing bores, rotary angle transmitter 3 body is bolted on sensor adapter plate 1, and sensor adapter plate 1 is fixed on again on wheel steering joint otic placode.And rotary angle transmitter 3 axle is fixedly connected with wheel steering shaft 6 by anchor shaft bolt 4, maintenance maintains static dynamic.During vehicle wheel rotation, wheel drives rotary angle transmitter 3 body to rotate, and makes rotary angle transmitter 3 body and axle have relative motion, thus realizes steering angle and detect in real time.But this detection mode easily occurs that the excessive or anchor shaft bolt looseness of stress causes sensor to occur the discontinuous of signal, unstable, even there will be sensor degradation phenomenon.
Mainly there is shortcoming in prior art:
A. time with single bolt anchor shaft, use after a period of time, bolt of rear end plate there will be loosening, and sensor axis and sensor can not realize real-time rotation, the discontinuous instability of signal, thus causes turning to inoperative, occurs that wheel flutter is asynchronous with " eight " word phenomenon;
B. on steering shaft, circular hole and sensor axis are installed when coordinating, and there is certain gap, when using bolt of rear end plate to fix, there will be the phenomenon of the stressed inclination of sensor axis, causing sensor signal to be jumped, even cause sensor degradation;
C. time with single bolt of rear end plate fixation of sensor axle, because fixation area is less, the stress amplitude ratio acted on sensor axis is more concentrated, when bolt of rear end plate predetermincd tension is excessive, sensor there will be signal and jumps and wild effect, thus the real-time continuous affecting steering angle detects, and causes occurring turning to serious hysteresis phenomenon etc.

The axle of described rotary angle transmitter extend in half accommodation hole on steering shaft through sensor adapter plate, and is clamped by steering shaft and block; Block is bolted and is connected on steering shaft.
Steering shaft is half cylinder-shaped shaft, more than half cylinder-shaped shaft or smaller part cylinder-shaped shaft, and namely steering shaft longitudinally cuts away a part and formed vertically on the basis of a circular shaft.
Described block is identical with the portion profile structure of cutting away.
The axle of described rotary angle transmitter is half cylindrical shaft, large semicircle columnar shaft or small semicircle columnar shaft, and described half accommodation hole coordinates with the axle construction of rotary angle transmitter.
The described center of circle of half accommodation hole and the axis coinciding of steering shaft.
Also comprise one and cover in protective cover outside sensor adapter plate and rotary angle transmitter, described protective cover is fixedly connected with otic placode.
Based on the above-mentioned self-travel type high-altitude operation platform turning to detecting device, it is characterized in that, sensor adapter plate is fixed on the otic placode that is connected with the steered wheel of high-altitude operation platform, otic placode and vehicle bridge hinged by steering shaft; Before steering cylinder, anchor shaft is connected with otic placode.
The beneficial effect that the utility model reaches:
(1) compared with prior art, the utility model adopts steering shaft and the block of new structure.The form of block and two bolt of rear end plates is adopted to fix rotary angle transmitter axle, ensure that block contacts with the whole semicircle axial plane of rotary angle transmitter, distribution of stress is even, there is not sensor axis stress raisers phenomenon, and block is connected with steering shaft by two bolts, fixing more reliable, axle is there will not be to loosen phenomenon, such rotary angle transmitter detects more accurate, avoids turning to of occurring because of prior art delayed, " eight " word phenomenon.
(2) compared with prior art, the utility model design turn in detecting device, rotary angle transmitter there will not be because axle is stressed excessive and rotate disalignment and the sensor degradation phenomenon that occurs.
