Abstract
The utility model discloses a car braking system. A car axle is equipped with a car axle gear (1) and the car axle gear (1) is engaged with a long moving gear (2); a shaft of the long moving gear (2) is connected with the shaft of a driven gear (4) through a clutch (3); the driven gear (4) is engaged with a transmission gear (5) and the transmission gear (5) is engaged with a braking gear (6); and a cam (7) and the braking gear (6) are installed on the same shaft and are connected with a brake (8). According to the utility model, by only providing energy for combining the clutch, the energy needed by braking is obtained by the rotation of car wheels, so that the car braking device has great significance on energy conservation and emission reduction, does not have too many complicated mechanisms and has the advantages of simple structure and easiness of overhauling.
Description
Technical field
The utility model relates to a kind of Vehicular brake device.
Background technology
Drum brake compresses on brake wheel by slipper and realizes braking.Now the main flow of drum brake mechanism is an internal expanding type, and its brake shoe is positioned at the brake wheel inboard, and brake shoe outwards opens in brake, and the inboard of friction braking wheel reaches the purpose of brake.Drum brakes is exactly to utilize brake facing static in the brake drum, and the brake drum along with wheel of going to rub is to produce the brake gear that the friction force speed that turns a wheel reduces.
All to be that gas is stopped, oil is stopped add some power-assisteds designs in the power of brake design now, and cart uses gas to stop more, and tracheae is big and small to have the hundreds of root, spreads in the crossbeam.Dolly uses oil to stop to add the ABS system mostly, and its complexity also is not less than cart, and all designs below the car floor, and these all bring very big difficulty to maintenance.Particularly cart has a place a bit to leak slightly, will cause air feed not enough, influence brake, and the very difficult place of finding gas leakage.
And use gas to stop and understand the power of consumption of engine, because be unique energy of braking as drg with the power driven air compressor of driving engine.
Summary of the invention
The technical matters that the utility model will solve:
A kind of new car brakeing engine installation is provided, to solve the problem of existing in prior technology complex structure or consumption of engine power.
The technical scheme of the utility model:
A kind of Vehicular brake device comprises drg, and the axletree gear is housed on the axletree; Axletree gear and long moving gear engagement; The axle of long moving gear is connected with the axle of driven gear through power-transfer clutch, driven gear and transmission gear engagement, transmission gear and spragging gear engagement; Cam and spragging gear are installed on the same axis, are connected with drg.
Power-transfer clutch is a magnetic clutch, is connected with car running computer.
Drg is a drum brakes, and two free ends of its brake shoe are provided with the jacking block cam between two jacking blocks.
The beneficial effect of the utility model:
1, step on brake pedal after, wheel will receive the friction and decelerate from power-transfer clutch and drum-type brake, the size of braking force depends on the strength that power-transfer clutch combines.
2, only the energy that power-transfer clutch is combined need be provided, the energy that brakes required relies on the rotation of wheel itself to obtain, and for energy-saving and emission-reduction very big meaning is arranged.
3, there is not too many complicated mechanism, simple for structure, be easy to maintenance.
Description of drawings:
Fig. 1 is the configuration schematic diagram of the utility model.
Fig. 2 is the side schematic view of figure one.
The specific embodiment:
Embodiment: present embodiment is the actuating unit of drum brakes, and its structure is following:
Mounting axles gear 1 on axletree, axletree gear 1 and long moving gear 2 engagements, the axle of long moving gear 2 is connected with the axle of driven gear 4 through power-transfer clutch 3; Employed power-transfer clutch 3 is a magnetic clutch, driven gear 4 and transmission gear 5 engagements, transmission gear 5 and spragging gear 6 engagements; Cam 7 is installed on the same axis with spragging gear 6; Drg 8 is a drum brakes, on two free ends of its brake shoe block 9 is housed, and cam 7 is between two blocks 9.
Working process: during cruising, power-transfer clutch 3 breaks off, and has only axletree gear 1 and long moving gear rotating; After chaufeur was stepped on braking vane 11, car running computer 10 combined with different current control power-transfer clutch 3 according to the dynamics of stepping on; Long moving gear 2 drives driven gear 4 and rotates; Driven gear 4 understands that through transmission gear 5, spragging gear 6 bands cam 7 rotates, and cam 7 turns an angle and will strut block 9, thereby the drg 8 of drum-type is started working; Cam 7, transmission gear 5, spragging gear 6 and driven gear 4 stop operating then, and wheel receives power-transfer clutch 3 and friction force that drg 8 brought simultaneously and stops gradually.In this process, the energy that power-transfer clutch 3 is combined only need be provided, drg 8 required energy rely on the rotation of axletree itself to provide.
