专利摘要:
The vehicle wheel of technical plastic has a rim (1) with a tyre bed (2) formed in it which is connected to a wheel disc (3) with holes (4) for fastening elements (9). Between the wheel disc (3) and a vehicle hub (5), a thermally insulating plate (8) is inserted. In order to minimise the reduction in the tightening torque of the fastening elements (9) due to operational heating of the vehicle wheel, axially evenly spaced pins (6) are inserted in the area of each hole (4), these pins being made of steel with a high yield strength and their end faces being in contact with support plates (7) which are arranged on both sides of the wheel disc (3). The linear coefficient of expansion of the pins (6) and the fastening elements (9) is thereby the same. …<IMAGE>…

专利说明:

The invention relates to an automobile wheel made of structural polymer materials and used in automotive engineering.
The aim of the invention is to increase the efficiency of operation.
Fig. „1 shows the proposed wheel mounted on a hub of a car, a longitudinal section; in fig. 2 - section aa on figs 1 „
The wheel consists of a rim 1 with a seat 2 for the tire. The rim 1 is connected to a disk 3 in which there are openings A for fastening elements. Pins 5 made of steel with high elastic limit are placed around each bolt hole 4 for bolts. The ends of pins 5 are in contact with supporting plates 6 installed on either side of disk 3. There is an insulating plate 8 between the wheel disk 3 and the hub 7 of the car. The linear expansion coefficient of the pins 5 is equal to the linear expansion coefficient of the bolts 9 "
During vehicle operation, when the wheels are subjected to loads and heating under heavy use of the braking system, the destruction of the structural engineering material under the action of the axial pressure of the bolts 9 is intensified, which leads to a decrease in the initial tightening torque. The material is destroyed in the area around the bolts 9 and between the support plates 6 that are in contact with the pins 5 "To prevent harmful influence in the area around the bolts 9 and between the support plates 6 installed on both sides of the disk 3, the number installed in the indicated areas in the axial the direction of the pins 5, their diameter and material are determined so that the total deformation of the pins

5 under the action of the axial pressure of the bolts 9 remained within the elastic zone of deformation of the material of the pins and, moreover, corresponded in its magnitude to the deformation of the structural material in the indicated zones
Example 1 A wheel made of polyamide 6 reinforced with 30% fiberglass, having pins 5 and support plates 6 made of 65c steel, and a heat-insulating plate 8 made of polyamine bismide reinforced with 65% fiberglass, was installed in laboratory conditions on a car hub 7 The four bolts 9 are tightened with the initial torque of 90 Nm. The hub 7 together with the wheel mounted on it is subjected to artificial electric heating in a static condition. When the temperature reaches 250 ° C, this heating level is maintained for 2 hours with an accuracy of + 10 ° CU. After this, the heating stops and the entire wheel-hub system 7 freely cools to 25 ° C without blowing and airing. This cycle repeats 10 times .
After the end of the first cycle, which is not included in the test, and the cooling of the hub 7, the initial tightening torque of the bolts 9 is monitored and, if necessary, this is done to fit the bolts 9, the supporting plates 6, the pins 5, the wheel 3 and 8 ”heat insulating plate
Measured at the end of the test in the direction of tightening the tightening torque of bolts 9 are in the range of 83-79 Nm, the initial tightening torque of bolts 9 is reduced by 8-12%, which is within acceptable limits set for safe operation of plastic wheels,
EXAMPLE 2 A wheel of polyamide 6 reinforced by 43% and 50% fiberglass, respectively, is tested under the conditions specified in example 10 Measured at the end of the test of bolts made of both materials, the tightening torque of the bolts) the direction of tightening) is in the range of 85-83 Nm, i.e., the torque of the contraction is reduced by 5-8%.
EXAMPLE 30 Two wheels of polyamide 6 reinforced with 30% glass fiber are installed on both front steps of an experimental passenger car. Four bolts 9 are tightened with an initial torque of 90 Nm0 Between the hub 7 of the car and the heat insulating plate 8 of the wheel wire thermocouples are installed to measure the temperature of the surfaces of these parts, which are subjected to heat due to intensive use of the brakes. The car receives a maximum load of 400 kg and runs smoothly along a 30 km long motorway at the same time. 40 braking operations are carried out in the speed range of 120–40 km / h with a slowdown speed.
negative acceleration of about 6 m / s at an ambient temperature of 19 ° C,
and reaches a level of 185-190 ° C. After 40 braking has been completed, the car is retracted to the stand where cooling of the heated hubs 7 in the static position should take place. Upon reaching 25 ° C, the hub torque is measured on the hubs 7. The moment of shaking has aged an average of 82. They, i.e., have decreased by 9%.
