Brake with two discs of fixed spacing
First Claim
1. A disc brake for a motor vehicle, comprising a pair of rotary discs, respectively an inner and an outer, fastened one to the other and with a fixed spacing, two pairs of friction elements, an outer pair and an inner pair respectively intended for coming into frictional engagement with opposite faces of the two discs, outer and the inner respectively, and support and control members intended for laying the friction elements of the two pairs against their respective discs and for absorbing the resulting braking torque, the brake comprising a supporting yoke extending both inside of the inner disc, in a gap between the two discs, and outside of the outer disc, a first clamping caliper, called an inner caliper, interacting with the inner pair of friction elements, and a second clamping caliper, called an outer caliper, interacting with the outer pair of friction elements, the two calipers being mounted slidably in the supporting yoke, the inner caliper comprising a body in the form of an upturned U, a base of which straddles the inner disc and has an outer wing descending into the gap between the two discs and coming into contact with an external friction element of the pair of inner friction elements, and an inner wing descending on the inner side of the inner disc, forming a cylinder, receiving a piston in contact with an internal friction element of the pair of inner friction elements, and the outer caliper comprising a body in the form of an upturned U, a base of which straddles the two discs and has an outer wing descending outside of the outer disc and coming into contact with an outer friction element of the pair of external friction elements, and an inner wing descending inside of the inner disc, forming a cylinder receiving a piston, and the caliper having a spacer in the form of an upturned U, a base of which straddles the inner disc in a radial gap separating the periphery of the inner disc and the base of the caliper and having an inner wing descending on the inner side of the inner disc in order to come into contact with the piston, and an outer wing descending in the gap between the two discs in order to come into contact with the internal friction element of the pair of outer friction elements.

Abstract
The present invention relates to a disc brake for a motor vehicle, comprising an inner (12) and an outer (14) disc, fastened one to the other and with a fixed spacing (D), an outer pair and an inner pair of friction elements for coming into frictional engagement with the opposite faces of the two discs, and support (16) and control (42, 42'"'"') members intended for laying the friction elements against their respective disc, the brake comprising a supporting yoke (16) extending both on the inside of the inner disc (12), in the gap (D) between the two discs, and on the outside of the outer disc (14), an inner caliper, interacting with the inner pair (40i, 40e) of friction elements, and an outer caliper, interacting with the outer pair (40'"'"'i, 40'"'"'e) of friction elements, the two calipers (42, 42'"'"') being mounted slidably in the supporting yoke (16). The inner caliper (42) comprises a body (44) in the form of an upturned U, the base (46) of which straddles the inner disc (12) and has an outer wing (48) descending into the gap (D) between the two disc (12, 14) and coming into contact with fraction element (40e) and an inner wing descending on the inner side of the inner disc (12), forming a cylinder (52), receiving a piston (54) in contact with friction element (40i). The outer caliper (42'"'"') comprises a body (44'"'"') in the form of an upturned U, the base (46'"'"') of which straddles the two discs (12, 14) and has an outer wing (48'"'"') descending on the outside of the outer disc (14) and comes into contact with friction elements (40'"'"'e) and an inner wing (50'"'"') descending on the inside of the inner disc (12), forming a cylinder (52'"'"') receiving a piston (54'"'"'), and the caliper (42'"'"') having a spacer (74) in the form of an upturned U, the base (26) of which straddles the inner disc (12) in a radial gap (I) separating the periphery of the inner disc (12) and the base (46'"'"') of the caliper and having an inner wing descending on the inner side of the inner disc (12) in order to come into contact with the piston (54'"'"'), and a outer wing descending in the gap (D) between the two discs in order to come into contact with friction element (40'"'"'i).
