Definitions

  • the invention relates to a motorcycle brake system according to the preamble of patent claim 1.
  • the brake system has a hydraulically actuated front and rear brake, in which can be constructed together and independently of each other via a foot and hand operated master cylinder brake pressure in the wheel brakes.
  • a hydraulically actuated front and rear brake in which can be constructed together and independently of each other via a foot and hand operated master cylinder brake pressure in the wheel brakes.
  • electromagnetically activatable intake and exhaust valves and a two-circuit pump drivable by an electric motor are used in the front and in the rear wheel brake circuit.
  • inlet and outlet valves and the pump additionally electrically actuated isolation and changeover valves in the two brake circuits available to build electro-hydraulic and thus autonomous manual operation of one of the two master cylinder brake pressure in the non-manually operated brake circuit, including the Pump and the separating and switching valve are electrically activated in not manually operated brake circuit.
  • a disadvantage of this brake system is the retroactive effect of the pump pressure on the manually operated master cylinder during an autonomous braking in one of the two brake circuits, whereby a pulsation on the hand or foot brake lever of the manually operated master cylinder is felt. Furthermore, especially when braking an uncomfortable hard feeling on the hand brake lever felt. It is therefore an object of the present invention to improve a motorcycle brake system of the specified type such that with as simple and reliable means no or only a negligible little reaction of the pump pulsation on each hand or possibly also foot-operated master cylinder occurs.
  • the brake system consists of a hydraulically actuated front and rear brake circuit 4, 10, each with one connected to the front brake 4, operated by manual power master cylinder 7 and a fußkraftproportional actuated master cylinder 13 on the rear brake 14th
  • electromagnetically operable intake and exhaust valves 6, 12 are arranged in the front and rear wheel brake circuits 4, wherein in each case a normally open inlet valve 6 is inserted into the brake pipe of the front and the rear wheel brake circuit 4, 10, respectively associated master cylinder 7, 13 with the front or the rear wheel brake 5, 14 connects via the open in the basic position of the separating valve 19.
  • the outlet valve 12 closed in the basic position is in each case inserted in a return line 15 of each brake circuit, which connects the front or rear wheel brake 5, 14, each with a low-pressure accumulator 16 and the suction path 3 of a dual-circuit split pump 9, which operates on the sudizikar.
  • the pump 9 is the pressure side with the brake lines 18 of both brake circuits in conjunction, so in a brake slip control phase a demand-driven return of each of the front and rear brake 5, 14 drained brake fluid volume is ensured in the brake lines 18 both brake circuits.
  • the pump pistons of the two pump circuits are driven jointly by an electric motor 2, so that without the circuit arrangements according to the invention to be explained in more detail below with the startup of the pump the pulsation of the pump pressure unhindered (either) on the hand-operated brake lever (or foot-operated brake pedal) would react
  • Both brake circuits 4, 10 are according to their circuit structure together and independently operable, with the peculiarity that, for example, in a manual actuation of the brake master cylinder 4 connected to the master cylinder 7 not only a brake pressure buildup in the front brake 5, but at the same time an electro-hydraulic brake pressure build-up in the rear wheel brake 14 takes place by the electric motor 2, the pump 9 is in operation, as soon as due to the rear wheel in the electrically initiated 10 open position of the changeover valve 20, the pump 9 takes pressure fluid from the master cylinder 13 and promotes the rear brake 14, while the isolation valve 19 in the rear brake 10 Pump pressure side of the master cylinder 13 separates.
  • a pressure sensor 21 is used as a rule.
  • the monitoring of the manually in the rear wheel brake pressure is controlled by means disposed in the vicinity of the master cylinder 13 pressure sensor 21.
  • both brake circuits are additionally provided with two wheel brake pressure sensing pressure sensors 21.
  • the master brake cylinder pressure detected by the pressure sensor 21 in the front wheel brake circuit 4 forms the command variable for electrical activation of the pump 9 acting in the rear and front brake circuits 10, 4, which, in cooperation with the intake and exhaust valves 6, 12, the separating and switching valve 19, 20 causes an automatic brake pressure control in the rear wheel brake circuit 10 according to a stored in the control unit 8 electronic braking force distribution curve, when only the front brake circuit 4 connected to the master cylinder 7 is actuated.
  • the brake master cylinder the pressure sensor 21 arranged in the 13 of the rear wheel brake circuit 4 forms the reference variable for electrically activating the pump 9, the inlet, exhaust, change-over and separating valve used in the front-wheel brake circuit 10.
  • a logic circuit is provided in the electronic control unit, in which, depending on the evaluation result of the pressure sensor signals by means of the electrically actuated pump 9, a hydraulic pressure is generated.
  • the control unit preferably forms an integral part of a brake unit 11 having the front and rear wheel brake circuits 4, 10, which is designed structurally as a monolithic block.
  • the control unit is plugged in an expedient embodiment for making electrical contact with the intake and exhaust valves 6, 11, switching and separating valves 20, 19 integrated in the brake unit 11.
  • the brake unit 11 can thus be attached to a motorcycle frame due to the particularly compact design in the vicinity of a battery.
  • a blocking tendency of the front and the rear wheel is reliably detected by means of wheel speed sensors and their signal evaluation in the control unit 8.
  • the inlet valve 6 arranged in the front-wheel or in the rear-wheel brake circuit 4, 10 is electromagnetically closed via the control unit in order to prevent a further pressure build-up in the front-wheel or rear-wheel brake circuit 4, 10.
  • the inlet valve 6 is opened for a limited time according to the requirement of the slip controller integrated in the control unit.
  • the hydraulic volume required for the pressure build-up is provided by the pump 9.
  • the hydraulic circuit of Figure 2 shows a modification of the circuit arrangement of Figure 1, according to the embodiment of Figure 2, the front brake 5 has a multi-piston brake, the brake piston in the associated wheel brake cylinders 5a, 5b, 5c independently of each other both from the brake pressure in Vorderrad- also in the rear wheel 4, 10 can be acted upon.
  • Figure 2 therefore advantageously eliminates the known from Figure 1 Trennventil- and Umschaltventilan extract in the front wheel 4, so that in the present embodiment of Figure 2 two of three wheel brake cylinder of the front brake 5 via the inlet valve 6 used in the front wheel 4 are directly connected to the first master cylinder 7, while the third wheel brake cylinder 5c is connected to the front brake 5 via a line branch 1 arranged on the rear wheel brake circuit 10 on the second master brake cylinder 13.
  • the rear wheel brake 14 can also be designed as a multi-piston brake, the Ren brake piston, however, are all connected via the brake line 18 of the rear wheel brake circuit 10 to the second master cylinder 13, which is operable via a foot brake lever.
  • the circuit arrangement according to FIG. 2 has a dual-circuit pump 9 whose pump suction valve 24 arranged in the front-wheel brake circuit 4 has a significantly higher opening pressure (about 1.2 bar) than the further pump-suction valve 25 (approx 0.2 bar), whereby an idling pulsation of the pump 9 in the front brake circuit 4 in the direction of the first master cylinder 7 is advantageously avoided during an autonomous braking of the rear wheel brake, whereby the hand brake lever can be operated without feedback.
  • the pressure-retaining valve 17 known from FIG. 1 is omitted from the low-pressure accumulator 16 of the front-wheel brake circuit 4, so that this low-pressure accumulator 16 has a simplified connection diagram.
  • both low-pressure accumulators 16 can be flushed through the return line 15 and provided with pressure retention valves 17 on the outlet side, which have an identical opening pressure (approximately 0.8 bar)
