Patent number: 10780866Abstract: A vehicle brake mechanism that includes a pedal, a piston attached to the pedal, a spring associated with the piston and exerting a longitudinal force on the piston in a direction opposite the braking direction in order to bring the pedal to a resting position, and an autonomous brake module. A manual braking force on the pedal causes a longitudinal movement of the piston and displaces a transmitter element integrally joined to the piston. The autonomous brake module causes a movement of an intermediate plate that displaces the transmitter element and the piston, exerting a longitudinal force on the piston in the braking direction. The brake mechanism determines the force in the direction opposite the braking direction using a sensor situated on or in the intermediate plate and/or the transmitter element.Type: GrantFiled: June 12, 2018Date of Patent: September 22, 2020Assignee: Robert Bosch GmbHInventors: Christian Jammes, Esteve Cortes Guasch

Patent number: 6070950Abstract: A braking control valve having a housing with at least one bore and a hydraulic piston (12) which slides in the bore to define and inlet chamber and an outlet chamber. The inlet and outlet chambers being sealed from each other by an elastic annular seal (14) which is carried by the piston (12). The inlet and outlet chambers are in communication with each other through a one way valve located in a passage in the piston which is actuated by a tappet. The seal (14) substantially has a rectangular cross section which is filled without axial clearance in a groove (120) in the piston (12). The seal has internal recesses which are exposed to any pressure present in the inlet chamber so as to urge the seal (14) against the bore with a force which varies as the inlet pressure in the inlet chamber.Type: GrantFiled: April 10, 1997Date of Patent: June 6, 2000Assignee: Bosch Systemes de FreinageInventors: Esteve Cortes Guasch, Juan Simon Bacardit, Fernando Sacristan

Patent number: 5720366Abstract: Disc brake having a caliper displacable on a stationary support to press a pair of brake shoes on each side of a brake disc, a brake operating device having a piston rod acting upon a rotating lever, the rotating lever rotates about a first axis perpendicular to the axis of the brake disc, the rotating lever interacting with a pressure piece by an eccentric bearing having a shaft which can be swivelled about a second axis on the rotating lever which second axis is offset with respect to the first axis of rotation of the rotating lever. The shaft of the eccentric bearing interacts with the rotating lever by coaxial cylindrical shaft situated on both sides of the pressure piece.Type: GrantFiled: October 20, 1995Date of Patent: February 24, 1998Assignee: Knorr Bremse AGInventors: Esteve Cortes Guasch, Joan Simon Bacardit, Jose Manuel Vila Boluda

Patent number: 5706916Abstract: A disc brake having a caliper (1) which straddles a brake disc (D) and a carrier (2) which is fixed to a vehicle. A cylinder (3) is secured to the caliper and closed by a piston 31. Guides (21a,21b,22a,22b) allow the caliper to slide with respect to the carrier (2) in response to an input to bring first (41) and second (42) friction pads into engagement with the brake disc (D) to effect a brake application. At least one of the first (41) and second (42) friction pads has ears (41a,42a) inserted in corresponding housings in the carrier (2). The housing constitutes guides for each ear which engage a lateral star-shaped spring (52a). The star-shaped spring (52a) provides a recoil which moves the first (41) and second (42) pads away from the brake disc (D) after each braking application.Type: GrantFiled: August 10, 1995Date of Patent: January 13, 1998Assignee: Bosch Sistemas De Frenado S.L.Inventors: Esteve Cortes Guasch, Juan Simon Bacardit, J.

Patent number: 5697475Abstract: A disk brake having at least one piston (14) which slides in a caliper (12), the caliper (12) sliding over a stationary support. The piston (14) being actuateable by a mechanical subassembly (22) having substantially first (24) and second (26) parallel plates. The first plate (24) being driven in rotation by a lever (32) about an axis (X--X') perpendicular to its surface. The second plate (26) being held in a stationary position with respect to rotation and secured to piston (14). A face on at least one of the first (24) and second (26) plates has a groove formed therein for receiving balls (28) to convert rotational movement of the first plate (24) into axial transulational movement of the second plate (26). The lever (32) has a first part (34) fastened onto an end (36) of a sheath of an actuating cable (38). The sheath (40) bearing on an end stop member (42) which is held stationary with respect to the caliper (12). The sheath (40) has an end stop member (42) which is formed on a brace member (44).Type: GrantFiled: January 16, 1996Date of Patent: December 16, 1997Assignee: Bosch Systemes de FreinageInventors: Gerard Le Deit, Claude Hulliger, Fernando Sacristan, Juan Simon Bacardit, Esteve Cortes Guasch

Patent number: 5482131Abstract: A power-assisted steering device having a piston located in a casing and driven by a rotational input from an input shaft. The piston has a sealing section for separating a first chamber from a second chamber and a transmission section. The transmission section having a U-shaped profile formed by two branches which are coplanar with the main axis of the casing. The branches form racks and mesh at respective geometric sites with toothed sectors which are integral with one another and an output shaft. A sleeve located in the U-shaped profile and connected to the piston prevents relative rotation of the piston and sleeve with respect to the main axis of the input shaft while allowing some relative radial translations with respect to the input shaft as the piston is moved in response to a pressure difference in fluids supplied to the first and second chambers to provide assistance in rotating the output shaft in response to an input applied to the input shaft.Type: GrantFiled: October 12, 1993Date of Patent: January 9, 1996Assignee: Bendix Espana S.A.Inventors: Esteve Cortes Guasch, Juan S. Bacardit

Patent number: 5461964Abstract: A roller-contact bearing device with a reduced clearance for a power-assisted steering system having a first roller-contact bearing for absorbing axial forces exerted on a steering shaft and a second roller-contact bearing for transmitting the axial forces to a casing. The second roller-contact bearing is urged toward shaft by an spring disc to oppose the axial forces being applied to the shaft.Type: GrantFiled: October 12, 1993Date of Patent: October 31, 1995Assignee: Bendix Espana S.A.Inventors: Esteve Cortes Guasch, Raimon Soler Bruguera

Patent number: 5454290Abstract: A hydraulic control device comprises a valve (4) which can be moved inside a casing (1) and a stop for opening the valve at one point, the position of which may be set. The stop (6) slides in an axial housing (7) under the effect of a spring (8) and a stop screw (9). The opening position of the valve (4) may be easily set from outside the casing (1).Type: GrantFiled: October 12, 1993Date of Patent: October 3, 1995Assignee: Bendix Espana S.A.Inventors: Esteve Cortes Guasch, Juan Simon Bacardit
