Description
Technical field
The utility model relates to a kind of detecting device, and specifically a kind of suspension steering angle detecting device, belong to technical field of engineering machinery.
Background technology
Along with development mechanical, electrical, hydraulic technique, new for total line control distributed electrical liquid proportional independent steering control system, owing to having rapidity, stability, the advantage that control accuracy is high, can also according to different mode of operations, performance figure to realize different control algorithms, therefore be widely used in engineering truck simultaneously.And this new for total line control distributed electrical liquid proportional independent steering control system, detect in real time and proposed very high requirement hanging steering angle.
Traditional angle detection device generally adopts the connection modes such as coupler, although can reduce to a certain extent the axial and radial load that angular transducer detects axle, often to have a moving velocity fast but due to engineering truck, load is large, steering frequency is high, the characteristics such as the large and longevity of service of mechanical shock make the angular transducer working environment very abominable.Angular transducer detects axle and repeatedly bears larger axial and radial load, thereby causing it to damage probability increases, greatly affect the use of engineering truck, reduce operation quality, stability and the safety of engineering truck, increase the expense of engineering truck operation and maintenance cost.
The utility model content
Problem for above-mentioned prior art existence, the utility model provides a kind of suspension steering angle detecting device, the detection axle that solves angular transducer repeatedly bear larger axis to the problem of radial load, guarantee the accuracy of detection angles, and then the operation quality, stability and the safety that improve engineering truck, the expense of reduction engineering truck operation and maintenance cost.
To achieve these goals, the technical solution adopted in the utility model is: a kind of suspension steering angle detecting device, comprise that angular transducer, revolution are supported, suspension, driving lever and shift fork, suspension is supported with vehicle frame by revolution and is connected, and angular transducer is positioned at and turns round on the axis that supports and be fixed on vehicle frame, and the detection axle on angular transducer connects driving lever, shift fork is fixed in suspension, adopts non-perfect rigidity to be connected between driving lever and shift fork.
Further, the detection axle on angular transducer connects by elastic cylindrical pin with driving lever.
The beneficial effects of the utility model are: the driving lever that detects the axle connection due to angular transducer connects with the connection non-perfect rigidity of employing that is fixed between the suspension upper shift fork, can detect axially and radially relatively moving of axle at angular transducer between the two, reduce and even eliminate the axial and radial load that angular transducer detects axle.Because the detection axle of angular transducer is connected by elastic cylindrical pin with driving lever, and adopt non-perfect rigidity to be connected between driving lever and shift fork, both detect on the axle hand of rotation at angular transducer and coordinate closely, can effectively guarantee to hang the accuracy that steering angle is measured.And then solve the larger problem of angular transducer damage probability, reduce the expense of the operation and maintenance cost of engineering truck, the operation quality, stability and the safety that improve engineering truck.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figures 2 and 3, a kind of suspension steering angle detecting device of the present utility model, comprise angular transducer 2, driving lever 4, shift fork 5, turn round support 6 and hang 7, suspension 7 is supported 6 by revolution and is connected with vehicle frame 1, and angular transducer 2 is positioned on the axis that turns round support 6 and is fixed on vehicle frame 1, and the detection axle on angular transducer 2 connects driving lever 4, shift fork 5 is fixed on and hangs on 7, and between driving lever 4 and shift fork 5, the non-perfect rigidity of employing is connected.Detection axle on angular transducer 2 is connected with driving lever and can be connected by elastic cylindrical pin 3.
As shown in Figure 1, owing to adopting non-perfect rigidity to be connected between driving lever 4 and shift fork 5, can drive shift fork 5 and move together when suspension 7 is rotated, shift fork 5 meeting driving driving levers 4 and then the detection axle that can drive on angular transducer 2 rotate, thereby detect the steering angle value of suspension 7.
Because the detection axle of angular transducer 2 is connected by elastic cylindrical pin 3 with driving lever 4, and adopt non-perfect rigidity to be connected between driving lever 4 and shift fork 5, can detect axially and in the radial direction relatively moving of axle at angular transducer 2 between the two, reduce and eliminated the suffered axial and radial load of angular transducer 2 detection axles even fully, effectively improved the service life of angular transducer 2, and then improved the reliability and stability of using this unit engineering vehicle, also reduce the use and maintenance cost of engineering truck.Because driving lever 4 coordinates closely on angular transducer 2 detection axle hand of rotation with shift fork 5, can effectively guarantee to hang the accuracy that 7 steering angles are measured simultaneously.
