Abstract
The utility model discloses an electric vortex dynamometer which belongs to a power absorbing device of a car chassis dynamometer. The electric vortex dynamometer comprises an axle assembly, and a plurality of excitation coils. The axle assembly comprises a principal axis and a disk which is fixed on the principal axis and is provided with a riser vent. A circular coil fixing plate is arranged on the principal axis through a bearing. A plurality of excitation coils are arranged on one side of the coil fixing plate facing the disk. A gap exits between the disk and the end surface of the excitation coil. The principal axis is further provided with a flywheel and a synchronous pulley. The electric vortex dynamometer is simple in structure, low in cost, good in heat dissipation, and long in service life.
Description
Technical field
The utility model belongs to a kind of vehicle performance proving installation, is meant the eddy current absorption dynamometer that a kind of chassis dynamometer is used especially.
Background technology
In chassis dynamometer, eddy current absorption dynamometer is a kind of device that absorbs the vehicle chassis output power, and it is to utilize the principle of current vortex loss to come absorbed power.Known eddy current absorption dynamometer structure as shown in Figure 1, on main shaft 1, a coil mounting bracket 5 is installed by bearing 2,8 field coils 3 are installed on support 5, have two stator plate 6 to be fixed on the main shaft 1,3 gapped 4 of stator plate and coils on coil 3 both sides.This eddy current absorption dynamometer field coil is many and arrange closely, and the heat that makes coil produce is difficult for distributing, temperature too high easy influence its measurement effect and serviceable life; Also to take cooling measure in order lowering the temperature in addition, on stator plate, to also have the fan leaf with forced air flow, thus its coil brace complex structure not only, and its general structure complexity, manufacturing procedure is loaded down with trivial details, the cost height.
The utility model content
At the problem that known eddy current absorption dynamometer exists, it is a kind of simple in structure that the purpose of this utility model is to provide, and cost is low, the eddy current absorption dynamometer of coil good heat dissipation.
In order to achieve the above object, the utility model adopts following technical scheme: eddy current absorption dynamometer comprises axle assembly, a plurality of field coil, and axle assembly comprises a main shaft and is fixed on disk on the main shaft, bleeder vent is arranged on the disk; The coil stationary dish that a circle is arranged by Bearing Installation on main shaft, a plurality of field coils are installed in the side of coil stationary card to disk, and be gapped between disk and coil end face.
On the main shaft of described axle assembly, can also be mounted with a flywheel.Described flywheel can be installed in a side of the no coil of coil stationary dish.
The coil of installing on the coil stationary dish can be 4, is that the center of circle is distributed on the coil stationary dish with the axle center of axle assembly.
A synchronous pulley can also be installed, so that the rotation of chassis dynamometer is passed to axle assembly on the main shaft of described axle assembly.Can certainly adopt the drum rotation axis of gear drive or and chassis dynamometer direct to connect by the shaft coupling knot.
Eddy current absorption dynamometer of the present utility model is compared with known eddy current absorption dynamometer has following advantage: do not have additional cooling structure, and coil brace is disk, easy to process so general structure is simple, cost is low; Because coil quantity is few, the space is big between coil, ventilate, thus good heat dissipation effect, long service life.
Description of drawings
Fig. 1 is the structural drawing of known eddy current absorption dynamometer;
Fig. 2 is an eddy current absorption dynamometer structural drawing of the present utility model;
Fig. 3 is the A-A view of eddy current absorption dynamometer shown in Figure 2.
Embodiment
Below in conjunction with the drawings and specific embodiments eddy current absorption dynamometer of the present utility model is described further.
As shown in Figure 1, eddy current absorption dynamometer of the present utility model has a main shaft 10, is welded with a rosette 13 on main shaft 10, and disk 13 is formed axle assembly with main shaft 10, on disk 13 right sides; A coil stationary dish 17 is installed on the main shaft 10 by bearing 15, in coil shaft collar 17 left sides four field coils 16 is installed, and 13 in coil 16 and disk are gapped; There is a flywheel 11 to be installed on the main shaft 10 on coil shaft collar 17 right sides; End at main shaft also is equipped with a synchronous pulley, is used for the rotation of dynamometer roller is passed to main shaft 10.
As shown in Figure 2, there is being bleeder vent 18 to be distributed in around the main shaft 10 with coil stationary dish 17 opposite circular 13 centers.Air enters from bleeder vent 18 during work, flows out between four coils, and the heat of taking away the coil generation is with cooling coil 16, because the space, space is big between coil, so air flow rate is big, cooling effect is much higher than the effect of eddy current absorption dynamometer shown in Figure 1.
From said structure as can be seen, with respect to known eddy current absorption dynamometer shown in Figure 1, not only field coil quantity reduces, and replace the coil brace of the complexity in the known technology with the coil stationary dish, do not need the fan leaf to force cooling coil yet, make its structure very simple, thereby processing and manufacturing is more prone to, processing cost and material cost are lower.
