The utility model is described in further detail for mode.
Herein, the terms such as " front, back, inside, outside " are position relationships based on ... shown in the drawings and establishment, with reference to the accompanying drawings
Difference, corresponding position relationship is also possible to change therewith, therefore, can not be understood as to the exhausted of protection domain
To limiting.
Referring to FIG. 1, Fig. 1 is a kind of trailer structure monocycly cornering ratio test disclosed in the utility model embodiment
The structural schematic diagram of instrument.
In a specific embodiment, trailer structure monocycly sideway force coefficient routine investigation machine provided by the utility model, it is main
It to be made of tractor 1, trailer 2 and the water pot 3 set on trailer 2, water injection system 4 and test wheel system 5 etc..
The axle 6 of trailer 2 is located at the rear side of its vehicle's center of gravity, and the leading portion of trailer 2 is overlapped on tractor 1 by towing pin 7
On the traction saddle 8 of back segment, the rear axle of tractor 1 bears a part of weight of trailer 2；Water injection system 4 and test wheel system 5
Quantity be two sets, point or so be set to trailer 2 car body both sides, and be located at 2 axle of trailer front side；Water injection system 4 is located at test
The front side of wheel system 5 simultaneously connects water pot 3 by pipeline, and water spray position corresponds to the detection wheel 55 of test wheel system 5, water spray
It direction can be towards rear or the back lower place.
In detection process, the water in water pot 3, which is continuously sprayed onto by water injection system 4 on road surface, forms moisture film to simulate down
Rainy day road conditions, test wheel system 5 measure cornering ratio on moisture film, water injection system 4 by control may be implemented watering amount with
The matching of speed ensures the consistency of road surface moisture film.
Each test wheel system 5 mainly by frame 51, drive upside down mechanism 52, guiding axis 53, counterweight 54 and one independent
The equal components of detection wheel 55 are constituted, and middle frame 51 is the installation foundation of entire test wheel system, for bearing test wheel system
Other building blocks are fixedly connected with the car body of trailer 2, drive upside down mechanism 52, guiding axis 53, counterweight 54 and detection wheel
55 equal components are all mounted on frame 51, wherein detection wheel 55 is installed on counterweight 54, and counterweight 54 is installed on by sliding sleeve leads
To axis 53, cooperation is slided up and down with guiding axis 53, and be connected to and drive upside down mechanism 52, drives upside down mechanism 52 and be equipped with by electricity
The elevating lever of machine, cylinder or Driven by Hydraulic Cylinder, effect are to drive counterweight 54 together with detection wheel 55 along about 53 guiding axis
It is mobile, in test, to put down counterweight 54 and detection wheel 55, make detection wheel 55 on the roads pressure effect Xia Yu of counterweight 54
Face contacts, the operating mode that simulating wheel is advanced on road surface, after test, can receive counterweight 54 and detection wheel 55 upwards
Rise, detection wheel 55 made no longer to be contacted with road surface, stop test, in order to avoid counterweight 54 and detection wheel 55 after putting down by upper and lower
Driving mechanism 52 influences, and drives upside down and floating connecting structure can be used between the elevating lever of mechanism 52 and counterweight 54.In this way,
After putting down counterweight 54 and detection wheel 55, drives upside down mechanism 52 and just no longer acted on to counterweight 54 and 55 application of detection wheel
Power only just applies the active force being lifted up when withdrawing.
Sensor (not shown) is provided in detection wheel 55, this sensor can be pulling force sensor, detection wheel 55
Holder one end and counterweight 54 be rotatablely connected, the holder other end of detection wheel 55 and counterweight 54 respectively with the both ends of sensor
Rotation connection, so that the horizontal force for generating detection wheel 55 in test is transferred to pulling force sensor.
The detection wheel 55 of test wheel system 5 on the left of trailer car body is diagonally disposed to left back, is located at trailer car body
The detection wheel 55 of the test wheel system 5 on right side is diagonally disposed to right back, the vertical symmetrical plane shape of each detection wheel 55 and trailer 2
At angle between 19.5 °~21 °, this angle can be specifically 20 °.
In addition, trailer, which is additionally provided with, accommodates water pot 3, water injection system 4 and the compartment 9 for testing wheel system 5,9 two bottom sides of compartment
The protection brush for being located at water injection system 4 and testing 5 periphery of wheel system can be equipped with.
Above-described embodiment is only the preferred embodiment of the utility model, is specifically not limited thereto, on this basis can basis
Actual needs is made with targetedly adjusting, to obtain different embodiments.For example, trailer 2 is set on rear side of center of gravity
There are two groups of wheels, alternatively, water injection system 4 and test wheel system 5 to be set to the unilateral side, etc. of trailer 2.Due to side in the cards
Formula is more, just no longer illustrates one by one here.
Since tractor and trailer are split structure, when discharge standard improves, user only needs replacing or upgrades
Standard tractor come meet country license discharge standard, and trailer and testing agency part then be not necessarily to any variation, to use
The use at family brings great convenience, and greatly reduces upgrade cost of the user to equipment, improves the satisfaction of user, promotees
Into the development of equipment vendors, it is also beneficial to the development of industry.
Moreover, the length of trailer do not influence normal driving, transition, under the premise of in field, can lengthen to greatest extent, water
Tank can lengthen therewith, to improve the cubical content of water pot, such as may be designed to the water pot of 10~15 tons of loading, and detection mileage number is almost
It can double, reduce the number of midway plus water, substantially increase detection efficiency.
Trailer structure monocycly sideway force coefficient routine investigation machine provided by the utility model is described in detail above.
Specific case used herein is expounded the principles of the present invention and embodiment, and the explanation of above example is only
It is to be used to help understand the core concept of the utility model.It should be pointed out that for those skilled in the art,
Without departing from the principle of this utility model, several improvements and modifications can be made to this utility model, these improvement
It is also fallen into the protection domain of the utility model claims with modification.
