Abstract
The utility model relates to an automobile chassis dynamometer system, which comprises two hydraulic brakes, wherein two rotating drums, two dynamometer motors and the two hydraulic brakes are in symmetrical and direct connection arrangement, the two rotating drums are in rigid connection through a shaft, the dynamometer motors are symmetrically arranged at both sides of the two rotating drums and are respectively connected with the two rotating drums through a shaft coupler, the torque and rotating speed information of the dynamometer motors and the hydraulic brakes is fed back into a central control system, and then, the central control system outputs new control signals to the hydraulic brakes and the dynamometer motors to realize the resistance setting of the dynamometer system.
Description
Technical field
The utility model relates to automotive performance test macro field, particularly a kind of dynamometer system for motorcar chassis.
Background technology
At present, automobile industry adopts chassis dynamometer system to come the exhaust emissions of measured automobiles, and test is quickened, slides with the oil consumption situation etc.But present most of dynamometer machine chassis dynamometer measuring accuracy is lower, generally adopts single cylinder, and cylinder surface is bare-barrel drum or knurled roll etc. mostly, and their surface attachment coefficient is all relatively low, does not reach precision prescribed.In sum, existing dynamometer machine is because the precision problem that cylinder causes awaits solution.
Summary of the invention
The purpose of this utility model is to address the above problem, and provides a kind of and can improve the performance test precision, the dynamometer system for motorcar chassis of situations such as the exhaust emissions of automobile, oil consumption.Be achieved through the following technical solutions:
The utility model father-in-law chassis dynamometer system of driveing a car, comprise central control system, two rotary drums and two dynamometer motors, it is characterized in that, also comprise two hydraulic brakes, described two rotary drums, two dynamometer motors and two hydraulic brakes are symmetrical direct connection and arrange, described two rotary drums are rigidly connected by axle, described two dynamometer motors are arranged symmetrically in described two rotary drum both sides and are connected with described two rotary drums respectively by shaft coupling, described two hydraulic brakes are arranged symmetrically in described two dynamometer motor two surveys, and connect described two dynamometer motors respectively by coupling shaft, the moment of torsion of described dynamometer motor and hydraulic brake and rotary speed information feed back to described central control system, and the resistance of realizing power-measuring system for described hydraulic brake and dynamometer motor by the new control signal of described central control system output is set again.
The utility model is the advantage of prior art relatively:
1, can get rid of the influence of extraneous factor, independent experiment;
2, two rigidly connected cylinders that adopt in the drum apparatus, the surface is through special grinding, and its attachment coefficient more approaches the road actual conditions;
3, this utility model has advantages such as test speed is fast, precision is high, expense is low, data stabilization, good comparability.
Description of drawings
Fig. 1 is the layout synoptic diagram of dynamometer system for motorcar chassis described in the utility model.
Embodiment
The 1-dynamometer motor; 2,3-cylinder; The 4-dynamometer motor; The 5-torque sensor; 6-central control system and CPU thereof; The 7-torque sensor; The 8-speed pickup.
Below in conjunction with the embodiment accompanying drawing the utility model is described further.
As shown in Figure 1, dynamometer system for motorcar chassis described in the utility model comprises central control unit 6, the drum apparatus under the cylinder 2,3, charger under the dynamometer motor 1,4 and sensor 7,8 etc.; Described two cylinders 2,3 be rigidly connected and between a speed pickup 8 is installed; Described dynamometer motor link to each other with cylinder by shaft coupling and dynamometer motor 1,4 on torque sensor 5,7 is housed, speed pickup 8 and torque sensor 5,7 link to each other with central control unit 6 again, to measure corresponding rotating speeds and torque.In test process, the tach signal of cylinder 2,3 and the dtc signal of dynamometer motor 3 feed back to central control unit 6 by speed pickup 8 and torque sensor 5,7 respectively, feedback signal process central control unit 6 receives, conversion processing is analyzed again and the control signal of setting is exported to described dynamometer motor 1,4, to realize the simulation of dynamometer system to various operating modes.
Two rigidly connected single cylinders 2,3 that adopt in the described drum apparatus, tire pressurized situation is compared more approachingly with it on the road surface, and slippage rate, resistance to rolling are little, the measuring accuracy height; Two rigidly connected single cylinders 2,3 that adopt in the described drum apparatus, the surface is through special grinding, its attachment coefficient more approaches the road actual conditions, can greatly improve the precision of chassis dynamometer aspect the automotive performance test, to realize the simulation of dynamometer system, satisfy the various demands of scientific research, automobile making and detection etc. to various operating modes.
The utility model mainly provides single cylinder of road actual conditions is more approached on a kind of surface through special grinding, surface attachment coefficient dynamometer system for motorcar chassis; to improve chassis dynamometer in the precision aspect the automotive performance test; under the situation that does not deviate from the utility model essence; the structural arrangement of dynamometer system for motorcar chassis can be done corresponding change, but these corresponding changes should belong to all within the affiliated claim protection domain of the utility model.
