Problems solved by technology

Although disc brakes are commonly used on the front axle of new models that have been launched recently, due to factors such as structure and cost, only a few imported high-end luxury models are equipped with complicated structures and expensive hydraulic disc brakes with parking functions.
Most passenger cars for ordinary users still adopt the layout scheme of front disc and rear drum. Due to the inconsistency of the front and rear braking performance, the improvement of the overall braking performance of the vehicle is limited.
The hydraulic disc brakes equipped with parking functions in foreign high-end luxury models have high requirements on vehicles, complex structures, and high costs. It is very difficult to promote them in China!

Embodiment Construction

[0057] The following is a detailed description in conjunction with the drawings and embodiments

[0058] 1. Overall

[0059] As shown in Figures 1 and 2, a pull arm assembly (10) is provided outside the brake, consisting of a pull arm (11), a fixing bolt (12), a torsion spring support seat (13), a torsion spring (14), and a cable bracket (15) Sequential assembly constitutes a parking brake force input and recovery mechanism; the pull arm (11) is connected with the ejector rod (24) with splines, and is assembled in sequence with the flat needle bearing (22) and the flat washer (21) to form a movement conversion mechanism. The rod (24) is assembled by the cage (32) and the steel ball and the push rod (45) to form a parking brake force transmission mechanism; the spring seat (47), the limit wire (48), and the conical spring (46) are assembled in The push rod (45) is fixed in the piston cylinder hole to form a recovery mechanism; the sealing screw plug (41), sealing ring (42), compres...

Abstract

This invention discloses a hydraulic disk integrated arrester based on a screw driven floating clamp composed of a pull arm component, a mandril component, a steel ball component, a push rod, a piston, a friction block, a caliper and a brake disk connected orderly, in which a clamp floating bracket is connected with the clamp by a guiding bolt, an installation bracket is connected with the floating bracket and fixed on a car bridge by bolts, which applies a special three-lockless screw structure to realize calm transfer of brake force and adjusts the working gap between a friction block and a brake disk automatically.

Description

Technical field [0001] The invention relates to a brake suitable for most passenger vehicles, in particular to a floating caliper hydraulic disc integrated brake based on screw transmission; the brake integrates two functions of driving and parking brake, and significantly improves the braking performance , Reducing the braking distance; effectively expanding the scope of application of disc brakes. Background technique [0002] Hydraulic disc brakes have been used in cars, light vehicles and other vehicles for 30 to 40 years. Disc brakes have the advantages of good heat dissipation, stable braking, good resistance to heat and water recession, and convenient maintenance. However, due to structural reasons, they face many difficulties in realizing the parking brake function required by the vehicle, making the disc brakes It is widely used only on the front axle of vehicles, while the rear axle still uses drum or drum disc brakes. Drum or drum disc brakes are complex in structure, ...
