- Pedal travel simulators enable a pedal travel (in the case of a handbrake, a lever travel) when a master brake cylinder is actuated in externally powered hydraulic vehicle brake systems.
- the brake master cylinder When actuated by an external force, the brake master cylinder serves as a setpoint generator for a hydraulic brake pressure that is not generated with the brake master cylinder but with external energy, for example with a hydraulic pump.
- the brake master cylinder is or will be hydraulically separated from the rest of the vehicle brake system during external power braking, for example by closing a valve, and when it is actuated, it displaces brake fluid into the pedal travel simulator, which communicates with the master brake cylinder during the external power braking.
- the international patent application WO 2018/091 195 A1 discloses a hydraulic block for a power-operated, hydraulic vehicle brake system.
- the hydraulic block is a narrow, rectangular metal block in which a pedal travel simulator is integrated.
- a cylindrical blind hole is attached in a narrow side of the hydraulic block, in which a simulator piston is received axially displaceable Lich.
- the blind hole is pressure-tight with a cylinder cover closed at one end, in which there is a disc spring package as a piston spring which acts on the simulator piston in the direction of a bottom of the blind hole in the hydraulic block.
- At the bottom of the blind hole opens a hole, which in the hydraulic block to a main brake cylinder linder bore leads.
- the hydraulic block or a blind hole to give the area of the hydraulic block forms a simulator cylinder of the pedal travel simulator, which also includes the simulator piston, the piston spring and the cylinder cover.
- the pedal travel simulator according to the invention with the features of claim 1 has a simulator piston which is displaceable in a simulator cylinder and which is acted upon by a first piston spring in the direction of a closed end of the simulator cylinder.
- the first piston spring is arranged in a hollow cylinder cover which closes an open end of the simulator cylinder - preferably fluid-tight and pressure-tight.
- Hollow means a shape of the cylinder cover that is suitable for receiving the piston spring and, if necessary, extends the simulator cylinder.
- the cylinder cover is, for example, zylinderrohrför mig and has an open and a closed end.
- a multifunctional part for example in the form of a perforated disk, is fastened to or in the cylinder cover on a side of the first piston spring facing the simulator cylinder and holds the first piston spring in the cylinder cover.
- the multi-function part is permeable to fluid, so that brake fluid can flow from the simulator cylinder into the cylinder cover and vice versa.
- a Abstandshal ter is arranged, which reaches through the multifunctional part and benfeder is acted upon by the first Kol in the direction of the simulator piston.
- the spacer transmits a spring force of the first piston spring to the simulator piston and acts on the simulator piston in the direction of the closed end of the simulator cylinder.

- the second piston spring and not the first piston spring acts on the simulator piston in the direction of the closed end of the simulator cylinder, so that a spring force acting on the simulator piston against the displacement direction of the simulator piston during the first displacement path is smaller than during the rest of the piston stroke, in which the stronger first piston spring hits the simulator piston over the spacer in the direction of the closed end of the simulator cylinder be. In this way, a so-called “jump-in” is implemented or simulated.
- the "jump-in” is a low pedal force or leverage at the beginning of a muscle force actuation of a master cylinder, which lasts roughly until the friction brake linings of all wheel brakes are in contact with the brake discs, brake drums or other brake bodies.
- a return spring in the master cylinder counteracts stepping on a foot brake pedal, pulling a hand brake lever or generally moving an actuating element of the master cylinder. If the friction brake linings of the wheel brakes are in contact with the brake pads, a further shift is generated
- a master cylinder piston in the master cylinder cylinder a hydraulic pressure that noticeably increases an actuation force.
- the pedal travel simulator according to the invention achieves the noticeable increase in force when, at the end of the first displacement path of the simulator piston, the first piston spring acts on the simulator piston in the direction of the closed end of the simulator cylinder, which during the first Displacement does not act on the simulator piston.

- the ßel 14 or the spacer 15 so short that there is a distance between tween the plunger 14 and an annular step 20 in the depression 19 when the simulator piston 6 rests on the closed end of the simulator cylinder 3.
- the simulator piston 6 has a first displacement path by which the simulator piston 6 can move in the simulator cylinder 3 before it strikes with its ring step 20 against the plunger 14 of the spacer 15 and applies a spring force to the first piston spring 17 via the spacer 15 which is directed towards the closed end of the simulator cylinder 3.
- ne helical compression spring is arranged as a second piston spring 21, which encloses the plunger 14 of the spacer 15 and one end of which is via a spacer ring 24 on the foot 16 of the spacer 15 and the other end on the ring step 20 in the depression 19 in the simulator piston 6.

- the external force brake pressure generator has an external force piston, not shown, in the external force cylinder, which is attached to the hydraulic block 1 coaxially to the simulator cylinder 3 on the outside, not shown.
- the electric motor is moved via a mechanical reduction gear and a screw drive in the external power cylinder.
- the master cylinder is hydraulically separated from the vehicle brake system by closing a solenoid valve, also not shown, which is also arranged in the hydraulic block 1, it serves as a setpoint value transmitter for the brake pressure to be generated and / or to be controlled wheel brake pressure.
- a solenoid valve not shown, in the hydraulic block 1, which is arranged in the bore in the hydraulic block 1, which forms the connection 4 of the pedal travel simulator 2 to the master brake cylinder, the pedal travel simulator 2 communicates with the master brake cylinder, so that when the muscle is operated Master cylinder brake fluid is displaced from the master cylinder in the simulator cylinder 3 of the pedal travel simulator 2.
- the brake fluid displaced from the master cylinder moves the simulator piston 6 in the simulator cylinder 3 against a low spring force of the second piston spring 21 until the simulator piston 6 (more precisely the ring step 20 in the recess 19 of the simulator piston 6) at the end of the first displacement path against the plunger 14 of the spacer 15 abuts.

Because the spring force of the first piston spring 21 is greater than the spring force of the second piston spring 17, the spring force acting on the simulator piston 6 increases when the simulator piston 6 is displaced further.
- the second piston spring 21 generates during the first displacement path of the simulator piston 6 shows a linear increase in force with a small slope, as FIG. 2 shows.
- the stronger, first piston spring 17 With a further displacement of the simula torkolbens 6, the stronger, first piston spring 17 generates a steeper, in the exemplary embodiment, progressive force increase.
- a length of the displacement path si which simulates the so-called “jump-in”, can be adjusted over the length of the tappet 14 and a depth of the depression 19 in the simulator piston 6.
- a spring force or a steepness of the force increase is adjustable by a spring hardness of the second piston spring 21 and by omitting the spacer ring 24 between the second piston spring 21 and the foot 16 of the spacer 15, a thinner or a thicker spacer ring 24 or more spacer rings 24.
- a rubber-elastic element which is generally referred to here as Elastizi ity 25, is arranged in the recess 19 of the simulator piston 6.
- the elasticity 25 ensures a smooth transition from the first displacement path S 1 to the further displacement of the simulator piston 6, which is denoted by S 2 in the force-displacement diagram in FIG.
- the spacer 15 or its plunger 14 is so long that it has a minimum distance between the annular step 20 in the recess 19 of the Simulatorkol ben 6, which forms an abutment for the second piston spring 21, and the foot 16 of the spacer 15, on which the second piston spring 21 supports, ensures that is longer than a minimum length of the second piston spring 21.
- the second piston spring 21, which in the exemplary embodiment is a helical compression spring, has its minimum length when its turns are in contact with one another.
- the spacer 15 avoids this contact of the coils of the second piston spring 21, which can also be understood as “going on block” of the second piston spring 21, through the length of its tappet 14.
- the stroke limitation is selected in such a way that it prevents the first piston spring 17 from “going into block”. "Going to block" of the first piston spring 17 would be a compression of the plate springs of the first piston spring 17 forming Disk spring package, so that the disk springs lie flat against one another and not just at their outer or inner peripheral edges and / or disk springs are pressed flat or snap into an opposite curvature.
- the hydraulic block 1 has the master cylinder bore 5, which in the embodiment is stepped in diameter and has circumferential grooves.
- a master cylinder (not shown) is pressed into the master cylinder bore 5, into which one or more master cylinder pistons (not shown) are introduced, one of which is displaceable for actuation of the master cylinder or the vehicle brake system with a brake pedal (not shown) and which or the other simulator piston ben are displaceable by pressurization.
- the hydraulic block 1 has the external force cylinder bore 22, which is located in a different sectional plane than the pedal travel simulator 2 and of which only a half section is therefore visible in FIG.
- the section is offset in the figures in such a way that the pedal travel simulator 2 can be seen as an axial section and the external force cylinder bore 22 as a half section.
- the hole in the hydraulic block 1 which forms the connection 4 of the simulator cylinder 3 of the pedal travel simulator 2 to the master brake cylinder, which can also be angled, passes the external force cylinder bore 22 without cutting it and opens into the master brake cylinder bore 5 or cuts it so that the simulator cylinder 3 communicates with the master brake cylinder hole 5.
