Description
Technical field:
The present invention relates to a kind of full automatic car speed detection equipment.
Technical background:
Speed detection apparatus is used for detecting and the accuracy of proof machine motor-car speedometer.Motor vehicles travels on the cylinder of equipment, rolling
Cylinder is modeled as the road surface of activity, owing to, in rolling process, the linear velocity of automotive wheel is equal with the linear velocity of cylinder, computer
Wheel actual speed, and then the accuracy of checking speedometer can be drawn by gathering calculating drum rotation speed.The most general speed inspection
The equipment of testing only have 4 rotate cylinders, outward add group free cylinder with the use of.This frame mode and method of testing, be only suitable for
In two-axle car and front axle speed can only be detected.The speed of multiple driving wheel can not be detected simultaneously, more can not realize the inspection of differential ratio
Survey.
Summary of the invention:
Present invention aim at providing a kind of full automatic car speed detection equipment, applicable any type of drive and any vehicle wheel base length
Vehicle Bus-Speed Monitoring, it is possible to realize all vehicle wheel rotational speeds and measure simultaneously, and then record differential ratio.Equipment comprises protecting component,
Surprisingly go out during being prevented from vehicle detection.
Technical scheme is as follows: this equipment is by device framework, velocity-measuring system, brakes, protecting component, industry control electromechanics
Brains etc. form.Placing some unit that tests the speed in framework side by side and constitute velocity-measuring system, device length is greater than maximum axle spacing vehicle to be measured,
So how long vehicle wheelbase the most to be measured, has how many drive shafts, can ensure that each wheel at least contacts with a cylinder surface,
So that equipment meets all driving wheels to many drive shafts, long wheelbase vehicle and measures the requirement of rotating speed simultaneously.
Accompanying drawing illustrates:
Fig. 1 is equipment overall schematic, and Fig. 2 is the unit that tests the speed, and Fig. 3 is brake unit, and Fig. 4 is front-wheel blocking means, Fig. 5
For earth anchor, Fig. 6 is that side wheel keeps off unit.
Complete equipment includes testing the speed 101-main body frame, 102-, and unit is some, 103-brake unit is some, 104-front-wheel blocking means,
105-earth anchor is some, 106-both sides wheel blocking means, 107-infrared emission switch etc..
Fig. 2 unit ingredient that tests the speed is: 201-cylinder, 202-toothed disc, 203-spring bearing, 204-sensor stand, 205-
Speed probe.Vehicle to be measured is parked on equipment, and each wheel can at least be in close contact with a cylinder.When vehicle wheel rotation,
Corresponding 201-cylinder and 202-toothed disc is driven to rotate.Wherein, the linear velocity of 201-cylinder is identical with wheel line speed, 202-
Toothed disc is identical with the angular velocity of 201-cylinder.Industrial computer can collect turning of 202-toothed disc by 205-speed probe
Dynamic speed, through calculating the linear velocity that can obtain wheel.
Fig. 3 brake unit consists of: 301-return spring, 302-brake lining assembly, 303-air bag.After 303-airbag aeration, will
302-brake lining assembly lifts, and is allowed to two 201-cylinder surfaces adjacent with top and compresses, utilizes frictional force to produce braking effect.303-
After air bags, under 301-return spring pulling force effect, revert to compressed configuration, make the 201-cylinder of correspondence be in free shape
State.
Fig. 4 front-wheel blocking means consists of: 401-roller, 402-bearing, 403-cover plate and support, 404-lift parts, 405-
Base support, 406-air bag.After 406-airbag aeration, 404-lifting parts, 402-bearing, 401-roller together rise, 401-
Roller gear is in the wheel front of detection vehicle.Once vehicle is surprisingly gone out, and 401-roller contacts with wheel surface, and concomitant rotation,
Thus counteract the displacement of wheel, stop vehicle forward.During 406-air bags, it is compressed to original position, 401-by action of gravity
Roller is hidden in below 403-cover plate.During vehicle detection, 401-roller lifting to be in state, other time be in hidden state.
Fig. 5 earth anchor is made up of the pre-buried parts of 501-suspension ring and 502-.The pre-buried parts of 502-are steel pipe with holes, cement time pre-buried
Pouring fixing, cement can flow into steel duct by above hole, makes to pour and more fastens.
Fig. 6 both sides catch is made up of some catch unit, and each catch unit is made up of 601-support and 602 rollers, and wherein 602
Equipped with parts of bearings inside roller, can be freely rotatable.When wheel and 602-roller-contact, 602-roller can be driven to rotate,
So can play the effect to wheel side sheet resistance gear.
The following is the work flow of the present invention:
Vehicle sails into:
Industrial computer launch computer brakes, all 103-brake units corresponding 201-cylinder of braking, it is allowed to rotate, vehicle delays
Delay and reach equipment stage body.When vehicle front-wheel arrive first group of 102-test the speed cell position time, 107-infrared emission switch be triggered,
Now station machine computer controlled driver is stopped.The 401-column rolling part decilitre of 104-front-wheel blocking means rises, operator with bandage car
It is fixed on the 105-earth anchor of equipment.
Detection process:
Operator connects p-wire, and one end connects industrial computer computer, and the other end connects the OBD interface of vehicle driving computer to be checked.
Industrial computer computer detection is to after successful connection, and all 103-brake units are closed, and each 201-cylinder can rotate freely, so
Rear industrial computer prompting driver starts detection.Vehicle slowly accelerates, and station machine reads vehicle current vehicle speed in real time by OBD interface,
And read each 102-and test the speed the velocity amplitude of unit, the unit that tests the speed that wherein measured value is not zero is surveyed the speed being respective drive wheel
Angle value.When car running computer vehicle speed value is 40km/h, industrial computer records the velocity amplitude of current each driving wheel, and then calculates
Go out speedometer error and differential ratio.
Vehicle rolls away from:
After having tested, industrial computer computer controlled driver stop, when all 102-test the speed unit record speed be 0 time, 104-
The 401-roller of front-wheel blocking means is fallen, and 103-brake unit brakes all 201-cylinders, and operator unclamps 105-earth anchor bandage,
Vehicle slowly rolls stage body away from.Whole test process is complete.
