Description
Technical field
The utility model relates to the proving installation of a kind of motor vehicle damping force and axle load.
Background technology
In order to guarantee the security of motor-driven vehicle going, motor vehicle must have well behaved brake system, and the brake system performance is bad, and the danger that causes accident is arranged.
Existing roller brake tester is that the wheel of tested vehicle is placed on the brake drum, and with the rotation of motor head roll, the method for the power opposite with the brake drum sense of rotation that records during according to car brakeing is measured a kind of equipment with pilot block system power.The wheel lifting device of braking test board, general using cylinder or air bag realize, when wheel stand and cylinder axis departed from greatly, cylinder can bear bigger lateral stress, and friction force is also bigger, so the effective push of cylinder is more much smaller than theoretical thrust.When axle load was big, the platform raising device broke down or phenomenon such as stuck easily.
In addition, present most proving installation is to test damping force test and axle load as two independent devices, this mode makes the test of braking ability must be divided into two stations and arranges, both increased the space that device is arranged, also increased simultaneously the stop frequency in the test process, increase the time of test, reduce testing efficiency, increase labor intensity of operating personnel.
The utility model content
Technical problem to be solved in the utility model provides a kind of and the incorporate motor vehicle axle load testing device of brake platform.
The utility model solves the technological means that its technical matters takes: should comprise guide housing with the incorporate motor vehicle axle load testing device of brake platform and place drum-type braking force test board, rolling bearing and support, working cylinder, force cell in the guide housing; Described drum-type braking force test board places the middle position in the guide housing, the left and right sides of drum-type braking force test board is installed with bearing plate respectively, force cell is fixedly mounted on the below of bearing plate and fixedlys connected with the cylinder push-rod of working cylinder, the lateral surface of drum-type braking force test board and bearing plate is installed with rolling bearing and support respectively, and the rolling bearing of rolling bearing and support contacts with the inwall of guide housing.
Compared with prior art, the utility model has the advantages that:
1) braking force measuring apparatus and axle load measurement mechanism are united two into one, reduce the location number of times that stops, reduce the test duration, improve testing efficiency;
2) measure accurately test result repeatability, reliability height;
3) reduce test board height degree, reduce mechanism complexity, maintenance easy to use.

Embodiment
Proving installation of the present utility model has guide housing 2 and drum-type braking force test board 3, rolling bearing and the support 4, working cylinder 5, the force cell 12 that place in the guide housing 2.
Fig. 1 extremely guide housing 2 shown in Figure 3 is cuboid, and four inwalls are arranged; Middle position in the guide housing 2 is placed with drum-type braking force test board 3.In conjunction with Fig. 1 and Fig. 2 as can be known, the end face of the and arranged on left and right sides of drum-type braking force test board 3 (promptly vehicle as shown in Figure 1 sails the and arranged on left and right sides of direction into) is welded with bearing plate 14 respectively, and the lateral surface of the bearing plate 14 of and arranged on left and right sides respectively is installed with two rolling bearings and support 4.As shown in Figure 1, also be installed with rolling bearing and support 4 on the front and rear end of drum-type braking force test board 3 respectively.In conjunction with Fig. 1 and Fig. 3 as can be known, can be respectively two rolling bearings and support 4 respectively be installed in the upper and lower of the front and rear end of drum-type braking force test board 3.The structural relation of rolling bearing and support 4 is installed on the support 15 by rolling bearing 16 and constitutes as shown in Figure 5.Wherein, the support 15 of rolling bearing and support 4 is fixedly mounted on respectively on drum-type braking force test board 3 and the bearing plate 14, and rolling bearing 16 contacts with the inwall of guide housing 2, thereby guarantees that whole device is steady, weighs accurately and reliably.As shown in Figure 2, working cylinder 5 places the left and right sides of drum-type braking force test board 3 symmetrically respectively.Referring to Fig. 4 as can be known, the cylinder shell 7 of working cylinder 5 is fixed on the air cylinder base 11 by coupling bolt and nut 6; Force cell 12 is fixedly mounted on the below of bearing plate 14 and fixedlys connected with the cylinder push-rod 10 of working cylinder 5.During the work of the utility model device, working cylinder 5 is positioned on the level ground.
The characteristics of proving installation of the present utility model are to have concurrently the dual-use function of measuring damping force and axle load.
During work, vehicle sails on the working panel 1 of drum-type braking force test board 3 and is stopped at the midline position of drum-type braking force test board 3 by direction shown in Figure 1.Can measure damping force this moment by PC index drum formula damping force test board 3.When the misalignment of wheel position and drum-type braking force test board 3 is big, can rely on the rolling friction realization guide effect that produces between the inwall of rolling bearing 16 and guide housing 2 in rolling bearing and the support 4 on the one hand; The force of rolling friction that produces between the inwall because of rolling bearing 16 in rolling bearing and the support 4 and guide housing 2 is less on the other hand, can guarantee the effective push of lifting cylinder simultaneously, and when carrying out the axle load test, even if axle load is bigger, owing to be the bearing guiding, therefore neither the lifting device stuck phenomenon can take place, also can not influence the measuring accuracy of axle load.
When measuring axle load, pressure-air enters the inside of working cylinder 5 by the cylinder air inlet 13 of air cylinder base 11, this moment, pressure raise, the working piston 8 of working cylinder 5 moves upward and then promotes cylinder push-rod 10 and moves upward, and power is passed to bearing plate 14 by force cell 12, lift the drum-type braking force test board 3 that links with bearing plate 14 simultaneously and stop thereon vehicle, be fixed on the gravitational cue that force cell 12 is experienced and automatic checkout system is transmitted under the bearing plate 14 this moment, and transfer data to PC, thereby realize the axle load measurement.Weigh after the end, decompression in the working cylinder 5 descends whole device, waits for measurement next time.
