The utility model has the advantages of: 1. Simple structure, convenient assembling, 2. Low cost, 3. The accuracy tests the speed.
Description
Technical field
This utility model relates to a kind of special-purpose vehicle needing to detect GES, is particularly suited for determining the maintenance of surface equipment such as the pitch sprinkling car of asphalt distribution amount, synchronous sealing rubble car according to speed.
Background technology
The special-purpose vehicle reequiped by body with frame, such as pitch sprinkling car, synchronous sealing rubble car etc., in work progress, needs to detect in real time GES, in order to control the construction volume of equipment, ensures that unit pitch sprinkling amount does not changes with the change of speed.
Traditional velocity-measuring system has radar velocity measurement, magnet steel to test the speed two ways.Radar velocity measurement is relatively costly, is not particularly suited for Eco-power special-purpose vehicle, and radar is affected relatively big by ground, the vibrations of vehicle body will also result in test the speed inaccurate.Magnet steel the used sensor that tests the speed is magnetic approach switch, is affected greatly by magnetic medium, so needing to protect magnetic approach switch, it is to avoid sensing with the magnetic medium in addition to the magnet steel of the code-disc that tests the speed, rate accuracy is affected by environment bigger.
Summary of the invention
For the shortcoming of above-mentioned vehicle speed detection system, this utility model offer one is with low cost, test the speed simple vehicle speed detection system accurately, it is possible to achieve the rotation of the detection maintenance of surface equipment change speed gear box take-off (propeller) shaft such as pitch sprinkling car, synchronous sealing rubble car.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of simple vehicle speed detection system, it is characterized in that, including the fifth wheel (1) being assemblied on automobile gearbox take-off (propeller) shaft, the sensor stand (3) being fixed on change speed gear box be assemblied in that sensor stand (3) is upper and speed measuring sensor of gear (2) towards fifth wheel (1), speed measuring sensor of gear (2) sensing fifth wheel (1) produces pulse signal, and by surveyed pulse signal real-time Transmission to controller (4).
There are tooth top (1-1) and tooth paddy (1-2) in described fifth wheel (1) periphery uniformly at intervals along upper, when the tooth top (1-1) of fifth wheel (1) or tooth paddy (1-2) rotate to the detection range of speed measuring sensor of gear (2), the pulse signal that speed measuring sensor of gear (2) exports corresponds to high level or low level.
Described fifth wheel (1) is formed by 2 semi-involutions divided equally, and involutory rear clamping is assemblied on automobile gearbox take-off (propeller) shaft.
Tooth top (1-1) surface of speed measuring sensor of gear (2) and fifth wheel (1) keeps the gap of 1～3mm.
Described fifth wheel (1) center is provided with a bayonet socket adapted with power transmission shaft (1-3).
Described fifth wheel (1) leans with the adpting flange on automobile gearbox take-off (propeller) shaft, and fifth wheel (1) arranges multiple unthreaded holes (1-4) ordinatedly that match with multiple bolts of installation on adpting flange.
Described fifth wheel (1) periphery is 20～50 along the number of teeth quantity of upper formation.
The beneficial effects of the utility model are:
Fifth wheel in this vehicle speed detection system can directly be assemblied in power transmission shaft output flange, simple in construction, easy to assembly, with low cost；Using speed measuring sensor of gear to substitute traditional proximity switch, the shortcoming that nonmagnetic proximity switch is affected by magnetic medium, the frequency that tests the speed is up to 20,000 Hz, it is ensured that fifth wheel volume is little, the fifth wheel number of teeth is many, thus improves rate accuracy.

Fig. 1 is this utility model structural representation；
In figure: 1, fifth wheel, 1-1, tooth top, 1-2, tooth paddy, 1-3, bayonet socket, 1-4, unthreaded hole, 2, speed measuring sensor of gear, 3, sensor stand, 4, controller.
Fig. 2 is the schematic diagram of electric control system in this system.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of simple vehicle speed detection system, including fifth wheel 1, sensor stand 3, speed measuring sensor of gear 2, controller 4.Tooth top 1-1 and tooth paddy 1-2 it is evenly equipped with on fifth wheel 1 circumference, fifth wheel 1 installation dimension is determined according to automobile gearbox take-off (propeller) shaft and flange, fifth wheel 1 is assemblied in change speed gear box take-off (propeller) shaft from A-A punishment two halves, fixing sensor stand 3 on change speed gear box, speed measuring sensor of gear 2 is directed at fifth wheel 1 and keeps and tooth top 2mm gap.Fifth wheel 1 center is provided with a bayonet socket 1-3 adapted with power transmission shaft.Fifth wheel 1 leans with the adpting flange on automobile gearbox take-off (propeller) shaft, and fifth wheel 1 arranges multiple unthreaded hole 1-4 ordinatedly that match with multiple bolts of installation on adpting flange.After controller 4 detects square-wave pulse signal, it is achieved the real-time detection to speed.
As in figure 2 it is shown, controller 4 electrically connects with touch screen, speed measuring sensor of gear 2.When the tooth top 1-1 of fifth wheel 1 rotates to speed measuring sensor of gear 2 detection range, position as shown in Figure 1, speed measuring sensor of gear 2 output signal is high level；When speed measuring sensor of gear 2 is away from the tooth top 1-1 of fifth wheel 1, speed measuring sensor of gear 2 output signal is low level.Can realize detecting the rotation of the maintenance of surface equipment change speed gear box take-off (propeller) shaft such as pitch sprinkling car, synchronous sealing rubble car by speed measuring sensor of gear 2.Speed measuring sensor of gear 2 electrically connects with controller 4, when controller 4 collects the pulse signal that speed measuring sensor of gear 2 is sent, calculates actual vehicle speed.Controller 4 electrically connects with touch screen, and touch screen can show speed in real time.
