Description

Vehicle brake device
Technical Field
The application relates to the technical field of vehicle braking, in particular to a vehicle braking device.
Background
Vehicles are typically composed of four major parts, an engine, a chassis, a body, and electrical equipment. The chassis of the vehicle is used as an important component of the vehicle, and can support and mount the engine of the vehicle and various parts and assemblies thereof, form the integral shape of the vehicle and receive the power of the engine so as to enable the vehicle to move and ensure normal running. The vehicle chassis consists of a transmission system, a running system, a steering system and a braking system. The brake system is used as a key for ensuring the running safety of the vehicle, and the performance of the brake system is particularly important. In general, a vehicle brake system includes two independent sets of service brake devices and parking brake devices. The service braking device can forcedly slow down or even stop the running vehicle according to the requirement of a driver, so that the running safety of the vehicle is ensured.
Currently, almost all service brake devices for vehicles are friction type, and mainly include two main types, namely drum brakes and disc brakes. The disc brake may include a brake disc, brake pads, caliper pads, and a drive pump. When the vehicle needs to be decelerated or parked, the disc brake can drive the brake pads on one side to press the brake disc to the brake pads fixed on the other side through the driving pump, so that the brake pads on two sides of the brake disc are tightly attached to provide braking force for the brake disc, and the aim of forcedly decelerating or parking the vehicle is fulfilled. When the vehicle needs to run normally, the brake pad of the disc brake can be rebounded and reset through the elastic member connected with the brake pad. However, in the disc brake, if the elastic force of the elastic member is insufficient, a state in which the brake pad cannot be completely separated from the disc brake when the brake pad needs to release the braking force is liable to occur. The brake pad still provides braking force to the brake disc at this moment, is unfavorable for the safe smooth operation of vehicle.

The left end and the right end of the first brake pad 31 can be in sliding connection with the first sliding groove of the fixed retainer 21, so that the first brake pad 31 can be ensured to move along the set direction, and the first brake pad 31 can be overhauled or replaced in the later period. The left end and the right end of the second brake pad 32 can be in sliding connection with the second sliding groove of the fixed retainer 21, so that the second brake pad 32 can be ensured to move along the set direction, and the second brake pad 32 can be overhauled or replaced in the later period. The lower end of the movable retainer 22 can support the lower side surface of the first brake pad 31, and the upper side surface of the second brake pad 32 can be abutted with one end of the driving part 23, so that the first brake pad 31 and the second brake pad 32 which are easy to damage can be replaced in the later period. One end (e.g., the lower end in fig. 3) of at least one rebound lever 33 is detachably connected to one side of the first brake pad 31 in the width direction, so that the rebound lever 33 can be easily overhauled or replaced at a later stage. The other end (upper end in fig. 3) of at least one rebound lever 33 is detachably connected to one side of the second brake pad 32 in the width direction, so that the rebound lever 33 can be easily overhauled or replaced at a later stage. One end of the at least one resilient sheet 34 may be detachably connected to one end of the first brake sheet 31 and/or the second brake sheet 32 in the longitudinal direction, and the other end may abut against the upper side and/or the lower side of the fixed holder 21. As shown in fig. 3, two rebound rods 33 may be symmetrically disposed at one side of the width direction of the first brake pad 31 and the second brake pad 32, and four rebound plates 34 may be disposed at two ends of the first brake pad 31 and the second brake pad 32 in a vertically opposite manner, so as to provide uniform and stable elastic forces to the first brake pad 31 and the second brake pad 32 at different positions. The brake pad assembly 03 may include a braking position and a release position. The driving part 23 can drive the distance between the first brake pad 31 and the second brake pad 32 to be reduced, the rebound rod 33 and the rebound pad 34 gradually elastically deform until the opposite side surfaces of the first brake pad 31 and the second brake pad 32 are respectively abutted against the upper side surface and the lower side surface of the part of the brake disc 01, the brake pad assembly 03 at the moment is at a braking position, and the rebound rod 33 and the rebound pad 34 apply a first acting force to the first brake pad 31 and the second brake pad 32. When the brake pad assembly 03 approaches from the braking position to the releasing position, one end of the driving portion 23 abutting against the upper side surface of the second brake pad 32 contracts, the resilience force acting on the first brake pad 31 and the second brake pad 32 is released by the plurality of resilient rods 33 and the plurality of resilient pieces 34 in the process, and the opposite side surfaces of the first brake pad 31 and the second brake pad 32 can be respectively and quickly separated from the upper side surface and the lower side surface of the part of the brake disc 01 under the combined action of the plurality of resilient rods 33 and the plurality of resilient pieces 34 in different positions. When the opposite side surfaces of the first brake pad 31 and the second brake pad 32 are completely separated from the upper side surface and the lower side surface of the part of the brake disc 01, the brake pad assembly 03 is in the release position, the rebound rod 33 and the rebound pad 34 can restore the posture before deformation, and a second acting force can be applied to the first brake pad 31 and the second brake pad 32. The second acting force enables the lower side surface of the first brake pad 31 to be kept in fit with the movable retainer 22, and the upper side surface of the second brake pad 32 can be kept in fit with one end of the driving part 23 to play a pre-tightening role, so that the first brake pad 31 and the second brake pad 32 can be kept in proper postures as far as possible, and the braking effect of the brake pad assembly 03 is ensured. Wherein, the first effort is greater than the second effort to can avoid resilience that rebound pole 33 and resilience piece 34 provided can't make first brake block 31 and second brake block 32 and brake disc 01 completely separate, reduce the wearing and tearing of first brake block 31, second brake block 32, extension brake block assembly 03's life.
