Abstract
The utility model discloses a disk and drum type parking brake having both disk and drum brake functions, which comprises a disk and drum compound brake disc. Wherein, the middle of the compound brake disc is a drum type brake drum and a braking mechanism positioned in and matched with the drum type brake drum. The margin of the brake drum is a disk type brake disk and the both sides of the disk surface are arranged with a brake caliper assembly and form a disk type brake mate with the brake disk. The utility model has the disk and drum brakes functions.
Description
Technical field
The utility model discloses a kind of brake device for car, specifically is motor vehicle parking brake.
Background technology
At present, the brake system of automobile often adopts drum brake mechanism behind the shroud, and Parking Brake is integrated in the drum brake mechanism.Drum brake mechanism is made of back-plate assembly, wheel cylinder, brake shoe brake cheek and brake wheel usually, braking during standstill is by the braking during standstill torque arm in the parking brake cable pulling drum brake assembly, the braking during standstill torque arm is outwards opened, connected braking outwards struts along with opening of hand braking torque arm from the hoof assembly, and the braking neck body assembly of another side can open simultaneously along with the power that self-gap-regulating mechanism transmits.Braking tightly is pressed onto the inboard of brake wheel from the drag friction sector-meeting of the outside of, neck hoof assembly, thereby realizes the purpose of braking during standstill.Technique scheme can only provide the unitary system flowing mode of drum brake, can't satisfy the function of disc type brake simultaneously.
Summary of the invention
The purpose of this utility model provides a kind of disc-drum parking brake that has disc type and drum brake function concurrently.
For achieving the above object, the technical solution adopted in the utility model is: disc-drum parking brake, it is characterized in that: drg comprises a dish drum composite brakig dish, the middle part of this composite brakig dish is drum type brake wheel and the inner stop mechanism that is mated that is provided with thereof, the brake wheel edge is the plate-like brake disc, and its card both sides are provided with brake caliper assembly and cooperate with its formation disc type brake.
In technique scheme, the utility model is to utilize the plate-like brake disc to realize the purpose of service brake with the friction between the drag friction piece in the brake caliper assembly that is mated, on the other hand, braking during standstill is to spur the braking during standstill torque arm that is contained in the inner stop mechanism that is provided with of drum type brake wheel by drag-line, the braking during standstill torque arm is outwards opened, connected neck, outwards strut from hoof and to drive the inside face that its brake strip that is provided with tightly is pressed onto the drum type brake wheel inner chamber at dish drum composite brakig dish middle part, by the purpose of friction realization braking during standstill.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an A-A cutaway view among Fig. 1.
The specific embodiment
Referring to Fig. 1,2, drg comprises a dish drum composite brakig dish 10, the middle part of this composite brakig dish 10 is drum type brake wheel 11 and the inner stop mechanism 20 that is mated that is provided with thereof, brake wheel 11 edges are plate-like brake disc 12, and its card both sides are provided with brake caliper assembly 30 and cooperate with its formation disc type brake.Core of the present utility model is exactly that advantage with disc type and drum brake concentrates in together, and simple in structure and reliable, these are realized by above-mentioned dish drum composite brakig dish 10.
The braking during standstill torque arm 23 that described and brake wheel 11 constitutes in the stop mechanism 20 that drum brake cooperate links to each other with the Parking drag-line, in other words the first service power of disc type and drum brake comes from service brake and braking during standstill power respectively, promptly comes from service brake and parking brake power.
Use the utility model to carry out glancing impact, service brake can be referring to relevant prior art, simply says to be exactly friction between the drag friction piece 31 that utilizes in plate-like brake disc 12 and the brake caliper assembly 30, thereby reaches the purpose of service brake; And braking during standstill is realized by being contained in 20 actions of drum type brake wheel 11 in-to-in stop mechanisms, say that simply stop mechanism 20 comprises braking neck hoof assembly 21, braking is from hoof assembly 22, braking during standstill torque arm 23, brake shoe assembly 24, back-plate 25 and push rod 26 etc., spur the braking during standstill torque arm 23 that is contained in the drum type brake wheel 11 in-to-in round cavities by drag-line, braking during standstill torque arm 23 is outwards opened, connected braking outwards struts along with opening of braking during standstill torque arm 23 from hoof assembly 22, the braking neck hoof assembly 21 of another side can make braking neck hoof assembly 21 open along with the power that push rod 26 transmits, the braking neck, from hoof assembly 21, the drag friction sector-meeting of 22 outside tightly is pressed onto the inboard of drum type brake wheel 11 inner chambers, reaches the purpose of braking during standstill by friction.
