Eccentric only-pull structure type hydraulic brake callipers

Abstract

The invention relates to the technical field of brake calipers and in particular relates to a pair of eccentric only-pull structure type hydraulic brake calipers. The pair of eccentric only-pull structure type hydraulic brake calipers comprises a guide pin, a buffer sleeve, holding springs, an inner friction block, an outer friction block, an eccentric shell, a piston and an only-pull structure bracket. Two sides of the eccentric shell and the only-pull structure bracket are connected through the guide pin and the buffer sleeve, the eccentric shell and the outer friction block are connected through the holding spring, and the inner friction block and the piston are connected through the other holding spring. Compared with the prior art, the only-pull structure bracket with an outer beam isdesigned, so that the integral rigidity is improved, the machining stability is improved greatly, and the tolerance zone is reduced greatly, and therefore, more favorable support is provided to improve eccentric wear, noise and drag. The eccentric shell is matched with the only-pull structure bracket, so that the eccentric wear of a friction plate is reduced to the maximum extent, and low frequency and knock abnormal sound noises are improved. The drag, eccentric wear and noise conditions of the hydraulic brake calipers are also improved well.

Description

technical field [0001] The invention relates to the technical field of brake calipers, in particular to an eccentric pull-only hydraulic brake calipers. Background technique [0002] The brake caliper is fixed on the steering knuckle through the mounting hole of the bracket, and can slide relative to the bracket along the guide pin in the axial direction. Under the action of the brake pressure, the piston pushes the friction block on the piston side, so that the friction block on the piston side is pressed against the brake disc. At the same time, the brake pressure pushes the brake caliper housing to move along the guide pin, so that the friction block on the fist side also presses against the brake disc to generate braking force. Thus, both sides of the brake disc are clamped by the friction blocks and braked. The brake disc is fastened to the wheel hub again, so the wheel also stops turning. [0003] As the braking progresses, the friction block is constantly worn, and...

AI Technical Summary

Problems solved by technology

Large span, plane support, although the support is relatively stable, but the plane support forms a gap fit, which is easy to cause abnormal noise

Small-span, single-point support. Compared with large-span, small-span support is unstable, and single-point support is also likely to cause instability in the radial direction.
