Problems solved by technology

Most car factories are unwilling to change the rim specification, which makes the brake shape and rim interference unusable
Moreover, after the braking radius is increased, the wear of the friction plate will be more intensified and uneven, resulting in abnormal braking noise and reduced service life.

Abstract

A hydraulic double-cylinder brake caliper assembly, including a caliper body with two hydraulic chambers, the two hydraulic chambers are connected at the bottom, and pistons are respectively arranged inside; The inner friction plate and the outer friction plate, the friction surfaces of the two friction plates are opposite and both of them are in clearance fit with the brake disc; there are pin holes on both sides of the fixed frame, and the pin shaft slidingly matched with the pin holes passes through the bolts and the suspension on the outside of the caliper body. ear connection; the pin hole is provided with a bush that matches with the pin shaft, and an air release screw is provided on the caliper body, and an air release cap is provided on the air release screw. A hydraulic double-cylinder brake caliper assembly according to the present invention has two pressure cylinders. Under the condition that the braking effective radius is the same, the braking force generated by the double-cylinder brake caliper is higher than that of the single-cylinder brake caliper of the same specification. Twice, it can increase the braking force when the layout space is small and the effective radius cannot be increased, and at the same time, it can effectively ensure the stability of braking.

Description

technical field [0001] The invention relates to the technical field of vehicle brake systems, in particular to a hydraulic double-cylinder brake caliper assembly. Background technique [0002] With the rapid development of the automobile industry, customers have higher and higher requirements for automobiles. At the same time, customers have higher and higher requirements for driving comfort and power economy. Brake calipers, as one of the executive components of the automobile braking system, cooperate with brake discs and other components to realize the deceleration and parking of the automobile. [0003] Among the existing MPV models, the curb weight is about 1350kg, the full load weight is about 1800kg, the wheelbase is about 2750mm, and the wheels are 15-inch / 16-inch. With the continuous improvement of people's purchasing power and the increasing requirements for car driving / riding space. It needs a vehicle with a curb weight of about 1500kg, a fully loaded weight of...
