    Field of the Invention
    The present invention belongs to the technical field of braking actuators
    10 hydraulic vehicles, and more specifically to the brake fluid reservoirs that are coupled to the hydraulic module of the braking actuator. The invention relates in particular to a brake fluid reservoir for the hydraulic braking actuator of vehicles, with a mechanical anchor for attaching to the hydraulic module centered longitudinally on the bottom base of the reservoir, and having a plurality of
    15 nozzles for connection to the hydraulic module that generate a torque on the tank with respect to the mechanical anchor. Additionally, the tank has a rebalancing joint that generates an additional torque on the tank with respect to the mechanical anchor that compensates for the torque generated by the nozzles connected to the hydraulic module. Background of the invention
    Nowadays, hydraulic brake actuators for vehicles are about integrating or directly connecting the brake fluid reservoir with the module
    25 hydraulic which includes the brake master cylinder and the brake pump with electric actuator.
    The brake fluid reservoir is arranged on the hydraulic module, directly coupling its lower base to the upper face of the hydraulic module. This
    30 arrangement allows the direct flow of the brake fluid from the reservoir to the brake master cylinder and the brake pump with electric actuator, while facilitating the filling of the brake fluid reservoir in the vehicle assembly line.
    The brake fluid reservoir is provided in its lower base with different 35 nozzles or connection ports, for the connection of the brake fluid reservoir with


    the different brake fluid chambers independent of the hydraulic module. In certain cases two nozzles are necessary, although the most common is that three nozzles are necessary, two for the primary and secondary chambers respectively of the brake master cylinder, and another for the pump chamber of
    5 brake with electric actuator.
    The tank must be fixed to the hydraulic module to prevent movement and disconnection of it. This fixation is done by means of anchoring that must fulfill several functions. They must first retain the deposit throughout the
    10 life of the vehicle in the correct mounting position on the hydraulic module. The anchoring means must also withstand the stresses produced during the brake fluid filling phase in the vehicle assembly line, and allow disassembly in a simple and quick way to perform maintenance, repair or replacement operations.
    15 Currently, these anchoring means consist of two different anchor points in the lower base of the tank, made by means of two pins that fix the tank to the hydraulic module and at the same time retain it in balance without movement on the hydraulic module. However, this current solution has the disadvantage
    20 of a high extra cost due to the two pins and the machining of holes and thread necessary in the hydraulic module for fixing both pins.
    A possible solution to this problem would be to make a single anchor point centered longitudinally on the bottom base of the tank, using a single pin
    25 which is fixed transversely to the hydraulic module through one or several tabs of the lower base of the tank.
    However, these anchoring means based on a single anchor point by means of a longitudinally centered pin in the lower base of the tank present the problem that it is not enough to retain the tank in balance and without movement on the hydraulic module, since the sealing joints of the nozzles exert a torque on the tank with respect to the anchor, around which it rotates said tank. Additionally, the force applied to the reservoir filling mouth during the brake fluid injection phase increases the applied torque.
    35 on the deposit, increasing its rotation.


    To solve this problem, the anchor point could be combined by means of the pin with a clipping of the base of the tank to the hydraulic module. This solution is also not effective because the deposit is made of propylene, which is not a
    5 material suitable for clipping, due to its low rigidity. In addition, complementary clipping means would have to be machined in the hydraulic module, which would increase manufacturing costs.
    A brake fluid reservoir for the brake actuator is therefore desirable.
    10 hydraulic vehicles that provide a complete and simple fixation of this to the hydraulic module, avoiding the inconvenience of the previous systems existing in the state of the art. Description of the invention
    The present invention solves the problems existing in the state of the art by means of a brake fluid reservoir for hydraulic vehicle braking actuator as described in claim 1.
    20 The brake fluid reservoir is coupled by its lower base to the upper face of the hydraulic module of the hydraulic braking actuator,
    The tank has a mechanical anchor in its lower base to be attached to the hydraulic module. This mechanical anchor has a single anchor point centered longitudinally at the bottom base of the tank.
    According to a preferred embodiment of the invention, the anchor point is made of a pin that is fixed transversely to the hydraulic module through at least one fixing flange arranged in the lower base of the tank.
    In addition, the reservoir has a plurality of connection nozzles that can be connected to the hydraulic module by means of seals for the passage of the brake fluid from the reservoir to the different connections of the hydraulic module to each of the independent hydraulic chambers of the brake actuator. In
    In certain cases, two nozzles are necessary, although preferably


    Deposit has three connection nozzles. A first connection nozzle connects the reservoir with the first connection of the hydraulic module to the primary chamber of the brake master cylinder. A second connection nozzle connects the tank with the second connection of the hydraulic module to the secondary chamber of the cylinder
    5 brake master. And a third connection nozzle connects the tank with thethird connection of the hydraulic module to the brake pump chamber.
    These connection nozzles with the gaskets that require proper operation generate a torque on the tank with respect to the anchor
    10 that tends to rotate the tank around said mechanical anchor.
    To prevent this rotation of the tank and that it moves from its position on the hydraulic module, the tank has a rebalancing joint arranged in a housing of its lower base in a position such that it generates an additional torque on
    15 the deposit with respect to the mechanical anchor, which compensates for the torque generated by the plurality of connection nozzles, such that the overall moment is zero and does not produce rotation with respect to the mechanical anchor, thus preventing movement and thus retaining the deposit in mounting position on the hydraulic module.
    20 Preferably, the reservoir has at least one fixing point of the rebalancing joint disposed in the housing thereof, for the support and fixing of said rebalancing joint. In this way, the rotation of the joint in its housing is avoided and this avoids possible clearances, malfunction of the joint, and even the possible exit of the joint from its housing.
    25 Although the rebalancing joint may have different configurations, it will preferably be the same as the connection nozzles, arranged in the housing in an inverted position to the connection nozzles, such that instead of protruding from the bottom base of the reservoir like the nozzles of connection, will be entered
    30 inside the tank, thus avoiding having to make recesses or complementary housings on the upper face of the hydraulic module. The fact that the rebalancing joint is equal to the connection nozzles makes it easier to manufacture.

    The object of the present invention is a reservoir of brake fluid for hydraulic vehicle brake actuator.
    As the figures show, the brake fluid reservoir 2 is configured 20 to be coupled by its lower base 3 to the upper face 4 of the hydraulic module 1 of the hydraulic braking actuator.
    The tank 2 has a mechanical anchor 11 at its lower base 3 for fixing to the hydraulic module 1. The mechanical anchor 11 has a single longitudinally centered anchor point 25 at the bottom base 3 of the tank 2.
    The figures preferably show that the mechanical anchor 11 of the tank 2 has a pin 15 that is fixed transversely to the hydraulic module 1 through at least one fixing flange 16 (which could be two or more) arranged in the base
    30 bottom 3 of the tank 2.
    Once the invention is clearly described, it is noted that the particular embodiments described above are subject to modifications in detail as long as they do not alter the fundamental principle and essence of the invention.


    Additionally, as can be seen in the figures, the tank has nozzles 5,7,9 that can be connected to the hydraulic module 1 by means of sealing gaskets, for the passage of the brake fluid from the tank to the different connections of the module
    5 hydraulic 1 to each of the independent chambers of the braking actuator.
    According to a preferred embodiment shown in the figures, the reservoir 2 has three 5,7,9 connection nozzles. A first connection nozzle 5 connects the reservoir 2 with the first connection 6 of the hydraulic module 1 to the primary chamber 10 of the brake master cylinder. A second connection nozzle 7 connects the reservoir 2 with the second connection 8 of the hydraulic module 1 to the secondary chamber of the master brake cylinder. And a third connection nozzle 9 connects the reservoir 2 with the third connection 10 of the hydraulic module 1 to the brake pump chamber.
    15 These nozzles 5,7,9 generate a torque on the tank 2 with respect to the mechanical anchor 11, as can be seen schematically in Figures 4a and 4b. This torque tends to rotate the tank 2 around the mechanical anchor 11, which can cause instability and displacement of the tank 2 from its position on the hydraulic module 1.
    20 To avoid this rotation the tank 2, according to the present invention, has a rebalancing joint 12 disposed in a housing 13 of its lower base 3 in a position such that it generates an additional torque on the tank 2 with respect to the mechanical anchor 11, which compensates the torque generated by the connection nozzles 5,7,9.
    In accordance with a preferred embodiment of the invention, and as seen in Figure 6, the reservoir 2 has at least one fixing point 14 of the rebalancing joint 12 disposed in the housing 13 thereof, for the support and fixing said rebalancing joint 12, and thus preventing its rotation inside the housing.
    30 Preferably, the rebalancing joint 12 is equal to the connection nozzles 5,7,9, although arranged in the housing 13 in an inverted position to that of the connection nozzles 5,7,9. In this way, the rebalancing joint 12, instead of protruding from the bottom base 3 of the tank 2, as with the connection nozzles 5,7,9, remains
    35 introduced inside, avoiding recesses, machining or additional accommodation in


    the upper face 4 of the hydraulic module 1. In addition, being equal to the connection nozzles 5,7,9 facilitates its manufacture. Figure 7 shows in detail this rebalancing joint in an inverted position to that of the connecting nozzles 5,7,9.
