Definitions
- the invention relates to a hydraulically operated full-disc brake according to the preamble of the main claim.
- System on the brake disc can be rotated pulsating by a fraction of a millimeter, which neither sealing rings nor rubber protective bellows can prevent. These fractions add up.
- the invention is therefore based on the object of designing the application device of the brake in such a way that the radial center planes of the feed connector and ventilation connector cannot rotate relative to one another. This object is achieved by the characterizing features of the main claim.
- the measure specified in the sub-claim enables an advantageous further development of the full-lining disc brake specified in the main claim.
- FIG. 1 shows a half section through a vehicle wheel with a full lining disc brake, the application device of which is one
- FIG. 2 has a section corresponding to FIG. 1, but offset in the circumferential direction
- FIG. 3 shows a section through the vehicle wheel and the brake in accordance with the section line A-B in FIG. 1.
- FIG. 1 denotes a wheel which, together with a brake housing flange part ⁇ , is fastened to a hub 3 of a vehicle by wheel bolts 2.
- a brake carrier 5 pressed from sheet metal is fastened with screws 4.
- the brake carrier 5 On its rolled toothing 53, the brake carrier 5 carries axially freely movable brake discs 6 and 7, which each consist of two 180 ° segments and carry friction linings.
- the Brake discs 6 and 7 engage with inner circumferential toothing 6- ⁇ and 7 X in the outer circumferential toothing 53 of the brake carrier 5 ( Figures 1 to 3).
- the brake discs 6 and 7 are encompassed by a circumferential, externally radially ribbed brake housing 8, 9 consisting of a brake housing flange 8 and a cover part 9.
- an application device 10, 11 which consists of two concentric annular pistons 10 and 11 and is sealed by square sealing rings 12 and 13, is also axially freely movable.
- the brake fluid for actuating the brake is the application device 10, 11 through an opening 5 ⁇ of the brake carrier 5 through brake hose 22, which is attached to the vehicle body, not shown, on the car body, and with one on the inner ring piston 10 of the application device 10, 11 by screws 21 Neck 20 supplied ( Figures 1 and 3).
- the brake fluid is passed into the annular piston chamber 14, which is Z-shaped in cross section.
- the feed connector 20 penetrates the brake carrier 5 through its axial recess 55 and thereby holds the application device 10, 11 in the circumferential direction.
- the annular piston chamber 14 is vented through a vent nozzle 15, the hexagon head of which is via a
- Socket wrench can be turned through openings Q ⁇ and 9 ⁇ of the brake housing 8, 9 ( Figure 1).
- a ventilation hose, not shown, is screwed into the internal thread provided in the ventilation pipe 15.
- the brake carrier 5 has openings 54 and 53 on the vehicle side, through which cooling air is conveyed between the back surfaces of the brake disks 6 and 8 when the brake rotates through openings 8 ⁇ _, 83, 9 ⁇ and 92 arranged on the outer circumference of the brake housing 8, 9 7 and the application device 10, 11 is passed in the direction of the arrow (FIGS. 1 and 2).
- part of the air penetrating through the openings 5 4 and 52 in the brake carrier 5 is also applied through the inside of the friction surface of the brake housing flange part 8
- the fenders 18 and 19 arranged between the brake disks 6 and 7 and the application device 10, 11 are of projections 10 through recesses ! and 111 penetrated the annular piston 10 and 11 ( Figures 1 and 2). These transmit the actuation axial forces when braking to the brake disks 6 and 7.
- the fenders 18 and 19 make by inner peripheral teeth 18 ⁇ and 19 ⁇ , which engage in the teeth 53 of the brake carrier 5, the circumferential fixation of the two annular pistons 10 and 11, so that no circumferential offset can occur between the feed pipe and vent pipe center planes.
