Description

rene pea ldol him. Each section with: 1; Shaped RPM-1 1. pivotally connected with supporting 2, on which ycT.r-.iJOB.TOH 1 turning mechanism 3, large) 1), nanpiRviep, in the form of a hydraulic cylinder and with a: p1 with a swing frame 1 At the ends of the supporting frame 2 there are mounted supporting bowls 4 (two on each side), interacting with prisms 5 fork arms 6, On levers 6 there are also fixed prisms 7, which rest on pillows 8, which can be mounted along the guides 9 funaa & ira. The free ends of the forked steps 6 through the roller (or prism) 10 are supported on the platform of weighing equipment - portable scales 11. The stand works as follows. Depending on the type of machine, the required number of sections is established on the foundation, one of which is fixed in the extreme position, and the other at the required distance from it. Then, the test machine mas enters the test bench and fastens it from the displacement on the pivoting frames 1. At that, the force from the weight of the machine through the support cushions 4 and the prisms 5 is transferred to the fork arms 6, which, resting on the pads 8 installed on the foundation, load the scales 1, based on the indications (taking into account the scale of measurement), the weight of the machine is determined between its distribution between the axles and the wheels (for wheeled vehicles) or between the steering wheels and drive sprockets and trolleys (for tracked vehicles). Then, the distances between the application currents of the components of the weight of the machine are measured analytically by two coordinates of the center of gravity. To determine the view center of the body (the third coordinate) at the same time using the lifting mechanism, lift the ends of the swing frames, tilt vrjjHy in the transverse plane by the angle CV.

Fig. 1 Since the distance between the prisms of the fork arms can be made small, and the length of the free ends of the arms can be varied in very wide parts, depending on the carrying capacity of the stand, standard portable scales can be used with a permissible measurement error of no more than OD%. In the proposed stand, a pair of friction, perceiving horizontal forces (the mount of the swing frame to the support and the mounting unit of the hydraulic cylinder) are not connected to the weighing devices, and the pairs of training pillow-prism only generate vertical forces, so that friction losses in such a system are minor (of hundredths of a percent of the weight of the car). These design features of the stand significantly increase the accuracy of the focal point of the coordinates of the center of gravity of transport vehicles. An invention of a stand for determining the coordinates of the center of gravity of transport vehicles, comprising support and pivoting frames relative to the trenal axis of the stand, mounted on a foundation with the possibility of mixing along the stand, frame rotation mechanisms and weighing devices, characterized in that it is equipped with forked levers, gphisms fixed on the levers, supporting pads mounted on the ends of the supporting frames and on the foundation and I JAW are supported for prisms, and free rims The levers are supported on weight measuring devices.
