Abstract
The utility model discloses a braking force test bench based on free drums. According to the utility model, a motor and a sensor device are arranged on the left side of a foundation frame; and a display control device is arranged at the middle part of the foundation frame. The braking force test bench based on free drums is characterized in that a power drum and a driven drum are arranged on the left side of the foundation frame; a power drum shaft is connected with the motor; the power drum shaft is connected with the driven drum through a transmission chain; and a free front drum and a free back drum are arranged on the right side of the foundation frame. According to the utility model, based on an original counter-force drum test bench, according to the principle of the braking force measurement of a counter-force type drum braking test bench, and based on the driving form and the wheel rotation principle of a multi-shaft driven vehicle with a through transmission shaft, drums on one side are changed into free drums to realize the test of braking force, thus the test of the braking force of the multi-shaft driven vehicle is convenient, fast and accurate.
Description
Technical field
The utility model relates to automobile brake perfrmance checkout equipment field, more particularly, is that a kind of damping force based on free cylinder is test bed.
Background technology
The braking ability of automobile is one of important usability of automobile.When automobile is subject to the external force opposite with travel direction, could or until stop from certain speed brake to the less speed of a motor vehicle.This external force is mainly provided by ground, is referred to as ground damping force.Ground damping force is larger, and braking deceleration is larger, and braking distance is also just shorter, so ground damping force has decisive influence to automobile braking performance.According to the regulation of GB18565-2001 " the commerial vehicle combination property requires and the method for inspection ", the detection of automobile brake perfrmance is divided into the brake tester detection and actual road test detects two kinds of methods.Generally speaking, available brake tester detects braking ability, when disputable to its result, detect with the road examination and rechecks.Stipulate according to national standard (GB7258-2004) " automobile safety running technology condition ", when using brake tester to detect, the number percent of damping force and complete vehicle weight is not less than 60, and the number percent of front axle braking force and axle load is not less than 60, and the number percent of rear axle braking force and axle load is not less than 20.
Brake tester can be divided into drum-type and flat two classes by the difference of supporting wheel form.Roller tester has can be divided into according to the difference of measuring principle anti-force type and inertia-type two classes.When using flush floor type brake tester, tested vehicle is in the mode of test slab employing brake hard, to detect the size of damping force.But be difficult for holding because vehicle reaches dull and stereotyped direction, so the error of damping force is larger, and the repeatability that detects is also lower.Anti-force type and inertia-type roller test stand all are that wheel is placed on the driving and driven cylinder in use, and the direct motor drive cylinder is to drive vehicle wheel rotation.Difference is, reaction type brake tester is the size of measuring damping force in the situation of emergency brake of vehicle, inertia type brake tester then is by adding the travel conditions of mode simulating vehicle on road of flywheel, detecting braking distance, braking time and the braking deceleration of each wheel.
But the brake tester usable range of drum-type is relatively limited, and the vehicle of four-wheel drive is to detect at common safety test line.The data that at first detect can not be reacted the value of damping force really, in addition, may damage the differential cross pin of vehicle.Therefore use above-mentioned two kinds of brake testeres just can't finish the detection of these vehicle braking abilities.
The utility model content
Problem to be solved in the utility model is to solve the braking forces measuring that the through shaft Multi Axle Drive Vehicle is arranged.In order to remedy the limitation of common counter-force drum braking monitor station, provide a kind of damping force based on free cylinder test bed.
The utility model is test bed based on the damping force of free cylinder, foundation frame left side mounted motor and sensor device, display control unit is installed at the foundation frame middle part, it is characterized in that, power drum and driven cylinder are installed in the foundation frame left side, the power drum axle connects motor, and the power drum axle connects driven cylinder by driving-chain, and free front roll and free back roll are installed in the foundation frame right side.
Along with the increase of four-wheel drive cars and multiaxis driving truck, the detection of its security performance is the assurance of vehicle safety and the prerequisite of vehicle driving.Yet with each wheel braking force measurements of through transmission shaft vehicle detection difficult on common counter-force drum braking power monitor station.The utility model is on the basis of original anti-force type roller test stand, measure the principle of damping force according to anti-force rolling brake testing platform, based on drive form and the vehicle wheel rotation principle considered with the Multi Axle Drive Vehicle of through transmission shaft, change one is sidewindered cylinder and is realized braking force measurements for free cylinder, so that it is convenient, quick, accurate to detect Multi Axle Drive Vehicle damping force.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that each axle left and right wheels of AWD car detects and draws numerical value and compare figure with the numerical value that detects by plane bench.
Embodiment
Be described further below in conjunction with 1 pair of the utility model of accompanying drawing.
As shown in Figure 1, the utility model foundation frame left side mounted motor 2 and sensor device 1, display control unit 6 is installed at the foundation frame middle part, power drum 5 and driven cylinder 4 are installed in the foundation frame left side, the power drum axle connects motor, the power drum axle connects driven cylinder by driving-chain 3, and free front roll 7 and free back roll 8 are installed in the foundation frame right side.
To vehicle detection the time, automobile is placed monitor station, the wheel that detects axletree is placed on the cylinder, simultaneously startup rotates and reverse motor, left and right sides cylinder switched in opposite, rotating speed equates.The driver records the size of damping force to car brakeing.With the method, change the parking stall, detect successively the damping force of other each axles.
The test figure checking
The utility model detects by each axle left and right wheels that time sharing car, AWD car and timesharing six are driven, and draws numerical value and compares with the numerical value that detects by plane bench, and it is feasible to draw the method.The below describes with regard to the battery of tests data.
Table 1 brave warrior (AWD) test figure
| ? | 1 time | 2 times | 3 times | 4 times | 5 times | 6 times | 7 times | 8 times |
| Common cylinder revolver damping force | 5800 | 6100 | 6550 | 6100 | 5900 | 6000 | 6350 | 5950 |
| Free cylinder revolver damping force | 6340 | 6820 | 6090 | 6550 | 5950 | 6430 | 6040 | 6000 |
According to the data that gather, can be found out to Fig. 2 that by top table 1 draw through test of many times, the data that the utility model institute test result draws meet the drawn data of China's national regulation braking forces measuring method, in the permissible error scope.For Multi Axle Drive Vehicle, when braking detects, change in the situation that a side is free cylinder, the damping force of detection meets the result that common cylinder detects.A utility model testing table i.e. side is that free cylinder is feasible, also is when solving the time sharing car and entirely driving and through driving vehicle braking force detects good method.
