Brake fluid reservoir for a hydraulic brake actuator of vehicles
A brake fluid reservoir for a hydraulic brake actuator of vehicles, which is coupled at its lower base to the upper side of the hydraulic module of the hydraulic brake actuator. The reservoir includes at its lower base a mechanical anchor, which fastens it to the hydraulic module and includes a single anchoring point, which is centered at the lower base of the reservoir in the longitudinal direction. The reservoir also includes several connecting nipples, which may be connected to the hydraulic module with the aid of sealing washers, which generate a torque on the reservoir in relation to the mechanical anchor. The reservoir includes a compensation seal, which is situated in a receptacle of its lower base in such a position that it generates an additional torque in relation to the mechanical anchor, which compensates for the torque generated by the plurality of connecting nipples.
1. A brake fluid reservoir for a hydraulic brake actuator of a vehicle, which is configured to couple at a lower base of the brake fluid reservoir to an upper side of a hydraulic module of the hydraulic brake actuator, the brake fluid reservoir comprising:
a mechanical anchor, at the lower base, configured to fasten the brake fluid reservoir to the hydraulic module and including a single anchoring point, which is centered at the lower base of the brake fluid reservoir in a longitudinal direction;
a plurality of connecting nipples, at the lower base, configured to be connected to the hydraulic module using respective sealing washers mounted on the connecting nipples, the connecting nipples together with the respective sealing washers generating a torque on the reservoir in relation to the mechanical anchor;
a compensation seal, situated in a receptacle of the lower base in such a position that the compensation seal generates an additional torque on the reservoir in relation to the mechanical anchor, which compensates for the torque generated by the plurality of connecting nipples together with the respective sealing washers;
wherein the compensation seal is identical to the connecting nipples together with the respective sealing washers, and is situated in the receptacle in inverted position relative to that of the connecting nipples.
2. The brake fluid reservoir as recited in claim 1 , further comprising:
at least one fastening point of the compensation seal situated in the receptacle, the at least one fastening point configured to support and fasten the compensation seal.
3. The brake fluid reservoir as recited in claim 1 , wherein the connecting nipples include:
a first connecting nipple which is configured to connect to a first fitting of the hydraulic module on a primary chamber of a main brake cylinder;
a second connecting nipple which is configured to connect to a second fitting of the hydraulic module on a secondary chamber of the main brake cylinder; and
a third connecting nipple configured to connect to a third fitting of the hydraulic module on a chamber of a brake pump.
4. The brake fluid reservoir as recited in claim 1 , wherein the mechanical anchor of the reservoir includes:
a pin configured to be fastened in a transverse direction at the hydraulic module by at least one fastening tab, which is situated at the lower base of the reservoir.
