Description
The utility model relates to a kind of performances of motor vehicles proving installation, belongs to the performances of motor vehicles test equipment.
At present, self-propelled vehicle dynamic property, braking ability detect and the average speed indicator verification is finished respectively by chassis dynamometer, brake test bench, speed meter checkout stand, as DCG-10 type chassis dynamometer, FZ-10 type brake test bench, SB-10 type speed meter checkout stand, or finish respectively by chassis dynamometer, the compound checkout stand of retro-speed table, as DCG-10 type chassis dynamometer, the compound checkout stand of ZSF-6A type retro-speed table.The integral test system that does not also have a kind of energy to concentrate measuring machine motor-car dynamic property, braking ability, carry out the average speed indicator verification, the Combination property of therefore testing a car bothers very much, and personnel, equipment, time is very waste all, and testing efficiency is low.
The purpose of this utility model is to provide a kind of integral test system that can concentrate measuring machine motor-car dynamic property, braking ability, carry out the average speed indicator verification, improves testing efficiency.
Design-calculated performances of motor vehicles combined test stand of the present invention is made up of cylinder, measurement mechanism, TT﹠C system, motor, power-transfer clutch, axle, bearing, gear etc., cylinder by bearing installation on axle, motor can turn round by head roll by gear, be characterized in being equipped with on the axle added mass, added mass is realized being connected and separating by power-transfer clutch with cylinder.
According to the present invention, tested self-propelled vehicle drive wheel is reached on the cylinder of two coaxial lines installations, turn round by the motor car engine head roll, record behind two drum rotation speeds revolution ratio according to diameter of cylinder and cylinder and driving engine, can try to achieve the linear velocity of engine speed and two cylinder excircles, promptly obtain the linear velocity of self-propelled vehicle drive wheel excircle, compare, realize verification average speed indicator with the average speed indicator indicated value.During machines motor-car braking ability, tested wheel is reached cylinder, after accelerating to certain rotating speed with the engine drive cylinder of motor or tested vehicle and wheel, with additional mass method (is a kind of method of measuring the kinematic scheme rotor inertia, groundwork is, angular deceleration when at first measuring the free reduction of speed of kinematic scheme, then to the additional added mass that rotor inertia is known of kinematic scheme, angular deceleration when measuring free reduction of speed behind the kinetic system regiment commander added mass again, before and after the band added mass, the angular deceleration of kinematic scheme and the rotor inertia of added mass, the retardance moment in the time of can freely slowing down in the hope of the rotor inertia of kinematic scheme and kinematic scheme.) measure the equivalent rotor inertia of part such as cylinder and tested wheel to cylinder axis, and the drag of part such as wheel, and then after wheel and cylinder accelerated to certain rotating speed, allow cylinder and wheel change free reduction of speed over to, implement braking, by measuring the cireular frequency and the variable quantity thereof of braking procedure intermediate roll, obtain the size of different lock torques constantly and braking force in the braking procedure, determine the unbalancedness of brake coordination time and left and right wheels braking force.During machines motor-car dynamic property, after accelerating to certain rotating speed with the engine drive cylinder of tested vehicle, measure cylinder with additional mass method, drive wheel, part such as driving system and driving engine is to the equivalent rotor inertia of cylinder axis, measure the angular deceleration of the free reduction of speed process of cylinder when comprising driving engine and not comprising driving engine then respectively, try to achieve the mechanical loss moment of torsion and the chassis retardance moment of tested vehicle driving engine, at last by the accelerated service of tested vehicle engine drive cylinder, measure accelerator intermediate roll rotating speed and variable quantity thereof, the horsepower output when obtaining the driving engine different rotating speeds, mechanical efficiency and chassis horsepower output, efficient.
The utility model is simple in structure, compact, it is few to take up an area of, not only can concentrate the measuring machine motor-car chassis horsepower output and efficient, braking ability, carry out the average speed indicator verification, but and at high speed measure the horsepower output and the mechanical efficiency of driving engine.
Accompanying drawing is the schematic diagram of mechanism of this utility model embodiment.
The utility model is described in further detail below in conjunction with accompanying drawing: cylinder 2 is installed on the axle 7 by bearing 8, motor 5 can turn round by head roll 2 by gear 9, be characterized on the axle 7 added mass 1 being installed, added mass 1 is realized being connected and separating by power-transfer clutch 6 with cylinder 2.TT﹠C system 4 is measured the cireular frequency and the variable quantity thereof of left and right sides cylinder respectively by measurement mechanism 3, by relevant processing, computing draw the respective detection result and show, printout.
When carrying out the average speed indicator verification, the tested vehicle driving engine rotates by drive wheel cylinder 2, TT﹠C system 4 records the cireular frequency of two cylinders by measurement mechanism 3, computing draws the linear velocity of cylinder 2 excircles, it is the linear velocity of drive wheel, compare with tested vehicle average speed indicator indicated value, realize the average speed indicator verification.According to the revolution ratio of drum rotation speed and cylinder and driving engine, can try to achieve engine speed.When the non-driving wheel braking ability detects, after accelerating to certain rotating speed with motor 5 head rolls 2 and wheel, measure the equivalent rotor inertia and the drag of parts such as cylinder 2 and wheel with additional mass method, and then after with motor 5 cylinder 2 and wheel being accelerated to certain speed, allow the free reduction of speed of cylinder 2 and wheel, and implement to brake, measure the cireular frequency and the variable quantity thereof of braking procedure intermediate roll 2, can try to achieve in the braking procedure size of different lock torques constantly of each wheel and braking force, determine the unbalancedness of brake coordination time and left and right wheels braking force.When detecting the drive wheel braking ability, the testing process of its process and non-driving wheel braking ability is basic identical, and just wheel and cylinder can be quickened by the tested vehicle engine drive.When detecting the dynamic property of vehicle, at first record the total yield rotor inertia and the drag of cylinder and drive wheel, the relevant movement parts of transmission system respectively with additional mass method, and the total yield rotor inertia and the drag of cylinder, drive wheel, transmission system, the relevant movement parts of driving engine, turn round by tested vehicle engine drive cylinder 2 steady accelerations then, TT﹠C system 4 records the cireular frequency and the variable quantity thereof of cylinder 2 by measurement mechanism 3, and then obtains the horsepower output and the efficient on rotating speed, moment of torsion, power, mechanical efficiency and the chassis of tested vehicle driving engine by relevant computing.
