This invention relates to the automotive industry.
Closest to the present invention is a vacuum brake booster of an automobile, comprising a casing of two extruded sections, divided by a diaphragm into a chamber connected to a vacuum source and to a chamber communicated with the atmosphere or a vacuum source through a valve a pusher for direct connection with the piston of the main brake cylinder, and on the other hand, through the transmission device, with the rod controlled by the brake pedal, each body section formed by a peripheral shell for tightly joining sections, the annular end wall coaxially to said shell with means of fastening to the master brake cylinder and mounting plate and connecting the shell to the end wall with ring rolled wall, all walls having the same thickness lj.
However, this device is characterized by insufficient strength of its casing.
The purpose of the invention is to increase reliability by strengthening the body without increasing its weight.
This goal is achieved by the fact that in an amplifier the annular concave wall is made with a radius of curvature in the longitudinal plane of symmetry diminishing in a parabola from both cable to the edge of the annular end wall.
Each section is made of 0.5 mm thick soft steel sheet.
Each section is provided with an amplifying element located on the inner surface of the annular end wall and adjacent edge to the annular concave wall.
The reinforcement element is made of a soft alloy.
The reinforcement element is associated with fastening means.
FIG. 1 shows a vacuum booster, longitudinal section; FIG. 2 is a diagram of the forces applied to the amplifier body.
The vacuum booster contains the housing 1, consisting of two sections 2 and 3 formed by the driver 1 {np4I

shells and 5, annular concave walls 6 and 7 and annular end walls 8 and 9. The peripheral part 5 of the diaphragm 10 is clamped between the shells A and 5. The diaphragm 10 divides the housing into the chamber 11 connected to the vacuum source by means of a check valve 12 and chamber 13 connected to a vacuum source and
10 atmosphere. The diaphragm 10 is connected to the core 14, in which the valve 15 is located to communicate the chamber 11 with the chamber 13 and the chamber 13 with the atmosphere. The valve 15 is controlled by a rod 16 connected to the brake pedal 17. A pusher 18 is located on the opposite side of the diaphragm 10 to interact with the piston of the main brake cylinder 19. On the end 20 of the walls 8 and 9 there are reinforcing elements 20 and 21 connected to the elements screws, which are screws 22 and 23 for connecting the case with the main brake
25 cylinder and mounting plate. Edges 24 and 25 screws 22 and 23 are adjacent to the concave walls 6 and 7.
The vacuum booster works as follows.
30 When acting on the brake pedal 17, the valve 15, under the influence of the movement of the rod 16, creates a pressure differential in the chambers 11 and 13, which causes the movement of the diaphragm 10 and, accordingly, the movement of the pushers 18 and the activation of the main brake cylinder.
Created on the pedal 17 force i (figure 2), the rod 16 transmits the pusher 18
Q as a force equal to the force multiplied by the gear ratio of the amplifier.
Force F tends to push the brake master cylinder 19 away from section 2, and on each of screws 22 it creates
5 tension tension F / 2. The same voltages (as seen from Fig. 2) will arise on the screws 23 connecting section 3 to the mounting plate. In working conditions under the action
0 of the indicated forces, the cylinder 19 moves to a distance e. The properties of the housing 1 depend on the radius R of the shells 4 and 5 of sections 2 and 3, the radius R of the end walls 8 and 9, and also the distance D along the axis of the amplifier and the edge of the shell 5 to the end wall 9.
The implementation of the walls 6 and 7 concave with a radius of curvature-in the longitudinal
