Technical field
The utility model belongs to the experiment detection device of automobile component, is specifically related to a kind of automobile gearbox endurance test bed.
Background technology
Automobile is divided into two-wheel drive and four-wheel drive two big classes, and is subdivided into forms such as preposition rear-guard, preposition forerunner, rearmounted rear-guard, mid-rear-guard in the two-wheel drive according to the difference of type of drive.At present, what use always in the car range two-wheel drive is preposition forerunner and preposition rear-guard, and corresponding wheel box is forerunner's wheel box and rear-guard wheel box.Automobile gearbox is the important component part of car transmissions, and the quality of its performance directly has influence on the performance of kinematic train, is related to the quality of car load.Therefore, country has enforceable requirement and standard to the endurancing of automobile gearbox.Existing wheel box endurance test bed mainly is made up of drive motor and the automatically controlled and measuring system of coupling, the loading electrical machine of simulated automotive wheel driving cycle and the automatically controlled and measuring system of coupling, tested wheel box and the test platen of simulated engine.
Preposition forerunner's principle of work is that motor car engine is passed through forerunner's wheel box and directly driven front axle, so the ratio of gear of forerunner's wheel box is bigger, output is high pulling torque, the slow-speed of revolution; The rear-guard wheel box of preposition rear-guard is to act on the automobile back wheel axle by automobile drive axle because drive axle contains reduction gear, so the ratio of gear of rear-guard wheel box is less, output be little moment of torsion, high rotating speed.For this reason, when two kinds of wheel box endurancings carrying out with power, automatically controlled and the measuring system of the drive motor of two kinds of wheel box simulated engines and coupling is identical, but because of the output difference of two kinds of wheel boxes, and the automatically controlled and measuring system of its loading motor and coupling, test platen are also different.
At present, wheel box manufacturer because the output torque of two kinds of wheel boxes is different with rotating speed, needs configuration two cover wheel box durability test devices when two kinds of wheel boxes (forerunner, rear-guard) of producing with power, therefore, cause that testing equipment investment is high, utilization factor is low.
Summary of the invention
The purpose of this utility model is at the above-mentioned defective that exists in the present technology, provide a kind of when wheel box power input identical (being that motor car engine is identical), forerunner and rear-guard wheel box can be tested the electric closed car wheel box endurance test bed of detection on the test battery platform.
The utility model is to realize above-mentioned purpose by the following technical solutions: this automobile gearbox endurance test bed, be used for the preposition forerunner of power and the endurancing of two kinds of wheel boxes of preposition rear-guard, it comprises the driving motor of a simulated automotive engine, the input speed torque sensor that is connected with tested wheel box input shaft, the loading electrical machine of simulated automotive wheel weight, the output speed torque sensor that is connected with the loading electrical machine, and the test platen that is used to install each testing equipment; Be characterized in:
When tested wheel box is preposition forerunner's wheel box, driving motor is connected with the input speed torque sensor by a constant speed transmission case, the input speed torque sensor is connected with the input shaft of wheel box again, and the two ends of the output shaft of wheel box then are connected with the loading electrical machine by the output speed torque sensor respectively;
When tested wheel box is preposition rear-guard wheel box, driving motor is connected with the input shaft of wheel box by the input speed torque sensor, the output shaft of wheel box then is connected with the input shaft of drive axle, the two ends of the output shaft of drive axle then are connected respectively on the output speed torque sensor, and the output parameter that makes preposition rear-guard wheel box is identical with output parameter with preposition forerunner's wheel box of power, and the output speed torque sensor is connected with the loading electrical machine again;
Described test platen is the T stage plate, and the constant speed transmission case is a right angle constant speed transmission case; Described driving motor is installed on the riser of T stage plate, and its shaft extension extreme direction is parallel with the riser direction, and two loading electrical machines are then installed the two ends on the transverse slat of T stage plate respectively, and the direction of its shaft extension end is also parallel with the transverse slat direction.
More particularly, described right angle constant speed transmission case is by gear transmission motion and power, and input shaft and the output shaft layout that meets at right angles, and its ratio of gear is 1.
Driving motor of the present utility model comes the simulated automotive engine operating condition by variable frequency control, the loading electrical machine is by energy back feed device simulated automotive wheel driving cycle, torque and speed sensors detects input, the output performance parameter of wheel box respectively, the technical parameter and the driving motor of input speed torque sensor are complementary, and the technical parameter of output speed torque sensor and loading electrical machine are complementary.Because the design of forerunner's gearbox designs is to cooperate installation with engine, when simulating, there is not the installing space of motor, so forerunner's wheel box and driving motor are connect by the constant speed transmission case with driving motor; Though the output of rear-guard wheel box is little moment of torsion, high rotating speed, by after the deceleration of automobile drive axle, its output parameter is identical with the output parameter of forerunner's wheel box.Therefore, forerunner and rear-guard wheel box for equal-wattage, except constant speed transmission case and automobile drive axle are the special use, other device all can be general, thus realized wheel box endurancing equipment investment reduce near half, utilization factor improves nearly one times beneficial effect.And, because of automobile drive axle has been adopted in the test of rear-guard wheel box, so test result is more accurate than prior art.
