Abstract
An improvement of an automobile braking test bench is achieved by using the physical law simulation technique, and comprises a motor (1), a reducer (2), a clutch (3), a roller (4), a pulley (5), an electromagnetic clutch (6), a force testing arm (7), an inertial flywheel (8) and a magnetic powder clutch (9). Wheel rotation speed and automobile speed during braking of an automobile can be accurately simulated, and automobile translational inertia and coefficient of friction of an automobile tire with a road surface can be simulated. Therefore, firstly, testing on automobile ABS (anti-lock brake system) dynamic high-speed braking efficiency and directional stability is achieved, and secondly, testing on roller counterforce type automobile braking performance is achieved. The improved automobile braking test bench has the advantages that firstly, testing on high-speed ABS braking performance is achieved, secondly, occupation is small, thirdly, efficiency is high, and fourthly, the automobile braking test bench is low in price and easy in popularization. Nowadays, high speed is open to everywhere, cars enter every household, both people's happiness and social operation lie on high-speed rotating wheels, and the high-speed ABS braking performance test bench improved on an original braking table can inevitably guarantee high-speed vehicle running safety.
Description
Technical field
The utility model relates to a kind of automobile brake check-out console, can realize the test of automobile ABS dynamic high speed brake efficiency and directional stability, can be used for vehicle safety performance measuring station and comprehensive vehicle performance measuring station and automobile factory.
Background technology
Estimate the safety of running car, key will be seen the braking ability (comprise brake efficiency and directional stability) of automobile when running at high speed, and automobile ABS generally uses on automobile, and purpose is exactly to improve brake efficiency and the directional stability of automobile when high speed.Find through investigation, when the vehicle inspection and test station of our country and maintenance depot are detected automobile brake perfrmance, the automobile brake test bed of use is divided into three kinds at present: drum reaction type automobile braking force monitor station and flat automobile brake test bed and inertia type brake tester, just detect the braking ability of automobile static state or low speed, all can not essence testing automobile ABS dynamic high speed brake efficiency and directional stability.Disclosed patent CN201037796Y " commercial car ABS composite braking monitor station " can assemble correctness, the detection of parts integrity to ABS, but emphasize in its instructions and can't the braking ability of automobile ABS have been detected.
Summary of the invention
Can only detect static low speed braking ability in order to overcome existing automobile brake check-out console, can not detect automobile ABS dynamic high speed braking ability, the utility model provides a kind of improvement of automobile brake check-out console, accurately simulated automotive tire and surface friction coefficient, but the translation inertia in the simulated automotive braking procedure also.Realized: 1. automobile ABS dynamic high speed brake efficiency and directional stability test; 2. drum reaction type automobile brake perfrmance test;
The technical scheme that is adopted is: between the left and right sides cylinder of the drum reaction type brake test bench that generally uses now, powder clutch, inertial flywheel group have been sealed in, thereby realized in the simulated automotive braking procedure, automobile translation inertia in simulated automotive tire and surface friction coefficient and the simulating brake process.Data shows: this is that the automobile brake check-out console is realized two necessary conditions that automobile ABS high speed braking ability detects.
Description of drawings
Accompanying drawing is a structural representation of the present utility model
1 motor, 2 reductors, 3 clutch couplinges, 4 cylinders, 5 sprocket wheels, 6 electromagnetic clutchs, 7 dynamometry arms, 8 flywheel groups, 9 powder clutchs
Embodiment
Original car test bench has 1 motor, 2 reductors, 3 clutch couplinges, 4 cylinders, 5 sprocket wheels, 7 dynamometry arms, the embodiment of technical scheme is to seal in 8 flywheel groups between cylinder, 9 powder clutchs and 6 electromagnetic clutchs, wherein: with the moment of inertia setting of 8 flywheel groups, translation inertia that can simulated automotive, moment of torsion setting with 9 powder clutchs, the torque value that surpass to be provided with promptly begins to skid, indirect analog skidding of doughnut and cylinder surface, promptly simulated the friction factor on doughnut and road surface.Realized the simulation of the friction factor on the translation inertia of automobile and road surface, as long as drum rotation speed is risen to the velocity amplitude of required test, can step on brake rapidly, can measure speed---the time curve of ABS high speed braking ability this moment, with retarded velocity, braking distance, braking time, promptly realized the detection of automobile ABS dynamic high speed braking ability.Analyze retarded velocity, braking distance, braking time, can estimate the height of automobile ABS brake efficiency; Analysis speed---time curve, when the speed difference of two wheels is big about in the brake process, i.e. direction instability during this car braking of decidable, otherwise, when the speed difference of left and right wheels was less, it was relatively stable to analyze the direction of judging in the Motor Vehicle Braking Procedure.
The utility model advantage: 1. realized automobile high-speed abs braking Performance Detection, 2. take up an area of little, 3. efficient height, 4. price is low, is easy to popularize.China of today, at a high speed be extend in all direction, automobile advanced huge numbers of families, people's livelihood happiness and society's running all have been placed on the wheel of high speed rotating, this on former brake platform, improve form can testing automobile ABS high speed braking ability the Vehicle Inspection platform, will make huge contribution for high speed traveling safety.
Claims (1)
