Description

TEST STAND

ELECTROMECHANICAL POWER STEERING VEHICLE

The proposed technical solution relates to measuring technique J, in particular, to measuring stands, and can be used for measuring mechanical alternating signs: loads, applied: :: output shaft of an electromechanical amplifier: steering wheel of a vehicle.

A known stand for the use of: products on impact, containing a table for installing the test product, which through elastic elements connected to the base :. reciprocating device connected to the table with the possibility of relative movement.

joints, and the elastic element is made in the form of pre-pressed from the ends of the strip and mounted on the base with the possibility of

adjusting the preload force, and in the middle of the strip, a table is fixed symmetrically relative to its ends with an earring in which is made step 3 in the vertical direction, etc. 1.

There is also a test bench for testing elastic axle boxes: knots, take as a prototype, containing a frame with supports mounted on it for installation1: and test: nodes and loading devices, it differs in that onopij is equipped with wedges, clamps and clamps -m-d, the middle support is equipped with a carriage that is capable of moving in the guide rail along the installation axes: lines: grooves, and the support devices are completed in the pressure cylinders mounted on both sides of the carriage 2.

The objective of the proposed technical solution is to simplify and reduce the cost of the product.

The problem is solved in that the test bench for electromechanical power; the steering wheel extender of the EUR.) Of the vehicle consists of a table for installing the test product, which is connected through the nodes: lugs to the loading device, the movable part of which is connected to the table, characterized in that the device the LOADER is equipped with a shaft. mounted in its support: a drum, on the axis: -: уст1зЭЭ уст уст уст уст уст уст уст уст;;;;;; lump and rope. A clamp is made at one end of the load device and a thread on which the carrier is placed, limited in movement from the sides by a stand rigidly fixed to the table, with the roller axis mounted on bearings.

Comparison of the analysis with the prototype showed that the proposed stand design contains much less constructive: nodes, which reduces its metal consumption and, accordingly, reduces the cost of the product as a whole, which meets the criteria of a useful model, such as novelty.

On fmg. shows a general view of the stand;

figure 2 - vertical bHbii i end. section of the stand; in Fig.Z is a vertical cross section of the drum and the stand roller.

The test bench for the electromechanical power steering (EUR) of the TpaHcnopiTHoro means consists of a table 1 of Fig. 1), on which a lodgement 2 is installed, intended for mounting a test sample of the EUR in it through clamp 3, and a loading device. Would :: -: the entire ZUE shaft (not shown in the drawing) is connected to the shaft 4 of the loading device installed in its supports 5 and 6. A drum 7 is installed between these supports (Fig. 1,2). The shaft 4 in its continuation through the support 6 ends with a thread on which the carrier 8 is located, limited in movement from the sides by a stand E rigidly fixed to the table 1, which allows adjusting the amount of rotation of the shaft 4 in both directions. On the drum 7 (Fig. 2) by means of the axis 10. on the sleeve: -: 11 a roller 12 is mounted with a steel cable 13. The cable is fixed in the drum 7 on the roller 12 with a shaft mounted on bearings, which is mounted on the roller 12, which There are excesses of the rope when changing the direction of the actual drum 7. In the lower part of the table 1, the suspension is with adjustable load 14 (Fig. 3), connected through the bracket to the roller 12 and to the knob-volume 13.

The device operates as follows.

On the lodgement 2, the EUR is installed and, with the help of the clamp 3, it is connected to the shaft 4. The voltage is supplied to the electric motor of the drive of the EUR through the command unit (in the drawing not showing a). You: one shaft of the EUR starts to rotate and rotates the shaft 4 with the drum 7 fixed on it, which, through the roller 12 with the rope 13 fixed on it, helps to wind the rope onto the surface of the drum 7, lifting or the load 14. The value of the load 14 creates the necessary moment of resistance1 -1 on shaft 4 and the output shaft of the EUR. After one turn of the advantageous shaft of the EUR, the control unit .gerekl.ochaet. ., rotation of the output shaft in the opposite direction by the required number of revolutions. It creates a z.chakperemennaya load on. you :: one shaft of the EUR. By changing the weight of the load 14, the necessary ones are selected: moment for mechanical 1 - p: tests of the EUR. The hpi-i rotation of the threaded end of the shaft 4 of the carrier S moves along the thread in the direction of the axle rack 9 i-r has limitations on the magnitude of the stroke, which serves as a protection against damage to mechanisms in case of control failure.
