Description
Technical field
The utility model relates to automotive inspection equipment, specifically a kind of drum reaction type automobile brake testing bench.
Background technology
The detection of automobile brake perfrmance is one of most important project in information of safety inspection for motor vehicles, domesticly use drum reaction type automobile brake testing bench in a large number at present, it is made up of the left and right two nested structure identical wheel braking force test cell be arranged symmetrically with and a set of measurement, control device.Every suit wheel braking force test cell is made up of frame, drive unit, cylinder group, lifting device, measurement mechanism etc.Utilize the simulating brake process that is used for of wheel braking force test cell and tested wheel, simultaneous measuring apparatus measures the damping force of left and right vehicle wheel two-wheeled.Conventional rollers anti-force type automobile brake testing bench motor and reduction gear external, general adopt the engagement of two-stage outer rotor to slow down or first-stage worm gear worm speed-down and primary gear speed reducing.This drum braking monitor station makes monitor station axial length larger because of motor, the external installation parallel with cylinder of speed reduction unit, and make speed reduction unit volume large because of the reason that reduction gear ratio is larger, cause whole monitor station height dimension comparatively large, outstanding ground, installs inconvenience.
Summary of the invention
The purpose of this utility model is to solve the problems of the technologies described above, provide and a kind ofly drive built-in drum reaction type automobile brake testing bench, this monitor station has that compact conformation volume is little, shaped flat is easy to install and use, noise is low, long service life, smooth running, reliable operation, good airproof performance, be applicable to plurality of advantages such as working in harsh environments.
Realizing the technical solution of the utility model is: a kind of drum reaction type automobile brake testing bench, comprises drive roll, follower rollers, drive unit, lifting jack and sprocket wheel; Drive arrangement is inner at drive roll, drive drive roll to rotate; Described drive roll and follower rollers are installed in parallel in frame, drive follower rollers to rotate by Chain conveyer.
Described drive unit comprises motor, reducing gear, is all built in drive roll inner space, and motor drives drive roll to rotate by reducing gear.
Described reducing gear is one-level external toothing and one-level internal gear gear train, comprises motor output end gear, duplicate gear and ring gear; The frame of motor and the frame of duplicate gear are arranged on drive roll axle, and ring gear is arranged on drive roll inwall, is connected as a single entity with drive roll; The first order is slowed down and is engaged with the right gear of duplicate gear for motor output shaft gear, and the left gear of duplicate gear engages with ring gear as slowing down in the second level.
Described drive roll is bearing on drum shaft by left and right bearing with end cover.
The drum shaft of described drive roll stretches out drum segment and connects torque sensor by shaft coupling.
The beneficial effects of the utility model are:
1, have compact conformation volume little, take up space little, transmission efficiency is high, noise is low, long service life, smooth running, reliable operation, good airproof performance, the plurality of advantages such as easy to install.
2, be adapted at working under various severe environmental conditions, comprise humidity, the working environment that muddy, dust is many.
3, compare with current roller anti-force type automobile brake testing bench, axial dimension and highly significantly reducing, whole brake platform flattening can be made.。
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model drive roll inner structure schematic diagram.
Number in the figure: 1-drive roll, 2-motor, 3-gear, 4-duplicate gear, 5-ring gear,
6-bearing seat, 7-torque sensor, 8-shaft coupling, 9-drum shaft, 10-motor reel, 11-follower rollers, 12-lifting jack, 13-sprocket wheel, 14-chain, 15-frame, 16-reducing gear.
Embodiment
As shown in Figure 1 and Figure 2: a kind of drum reaction type automobile brake testing bench, drive roll 1, follower rollers 11, drive unit, lifting jack 12 and sprocket wheel 13 is comprised; Described drive roll 1 is installed in parallel in frame 15 with follower rollers 11, and drive roll 1 is connected with follower rollers 11 by sprocket wheel 13, chain 14; Lifting jack 12 is installed between two cylinders; It is inner that described drive unit is arranged on drive roll 1, comprises motor 2 and reducing gear 16.Described reducing gear 16 adds one-level inside meshing gear speed reducer structure for one-level external toothing, comprise gear 3, duplicate gear 4 and ring gear 5, wherein the frame of duplicate gear 4, the frame of motor 2 are fixed on drum shaft 9, and ring gear 5 is fixed on the inwall of drive roll 1.The gear 3 that the first order is slowed down is contained on motor 2 output shaft 10, and engage with the right gear of duplicate gear 4, the left gear of duplicate gear 4 engages as slowing down in the second level with ring gear 5.Described drive roll 1 is bearing on drum shaft 9 by left and right bearing with end cover, can rotate around axle 9.Described drum shaft 9 is arranged in frame 15 by bearing seat 6, stretches out drum segment and connects torque sensor 7 by shaft coupling 8.
The course of work of the utility model measuring vehicle damping force is, when detected vehicle reaches monitor station, when wheel is between driving and driven cylinder 1,11, neutral hung by vehicle, and motor 2 starts.The output of motor reel 10 drives drive roll 1 to rotate around drum shaft 9 through two-stage gear reduction, and axle 9 does not turn, and drive roll 1 drives follower rollers 11 by sprocket wheel 13, chain 14 again.Driving and driven cylinder 1,11 drives detected wheel of vehicle low speed rotation simultaneously, and after vehicle wheel rotational speed is stable, driver steps on brake pedal, and wheel reduces speed now braking under the moment of friction effect of wheel drag.The tangential direction of cylinder to wheel tyre periphery that now motor 2 drives has an acting force to overcome brake frictional torque, maintain wheel to continue to rotate, meanwhile wheel tyre applies one and the reverse equivalent reacting force in damping force direction to cylinder surface tangential direction, stops drum rotating.Now, under moment of reaction effect, motor 2 rotates reverse direction towards cylinder and deflects together with drum shaft 9, and drum shaft 9 stretches out drum segment and connects torque sensor 7 by shaft coupling 8, input is produced to torque sensor 7, measures moment of torsion by measuring system and be converted to damping force.Measure complete, vehicle carries away by lifting jack 12.
The utility model, compared with the brake detection table of existing transmission external, has compact conformation, flat, volume is little, transmission efficiency is high, noise is low, the plurality of advantages such as smooth running, reliable operation, good airproof performance.
