Description
Technical field
The utility model relates to the retarder in a kind of brake system of car.
Background technology
Along with the development of high-grade highway, Vehicle Speed is more and more higher, and meanwhile, rate of traffic flow is also increasing, and thus the brake load of vehicle is also increasing.If these brake loads are all born by service brake, will cause brake drum and brake strip overheated, thus cause brake efficiency to decline, even stopping power disappears completely; This is that the safety requirements of vehicle is unallowed.In addition, the overload of service braking system, also can make the life-span of brake drum and brake strip greatly shorten, and the use cost of vehicle and maintenance load are strengthened.Therefore, address these problems, more practicable method installs complemental brake system exactly.
Current Technical comparing complemental brake system that is ripe, that be applicable to entrucking has: engine braking, current vortex retarder, Retarder and permanent-magnet buffer, self-excitation retarder etc.
Wherein permanent-magnet buffer structure is the simplest, has good prospect; But existing permanent-magnet buffer generally adopts arc magnetic pole to be alternately arranged, magnet installs inconvenience, and because magnet installing space is limited, braking moment is less; And not easily realize becoming braking moment, to adapt to different braking working condition requirement.
Utility model content
The purpose of this utility model is to provide a kind of variable torque permanent-magnet speed buffer.The magnet of this retarder is the fan-shaped of annular or negligible amounts, is placed on retarder shell inner face; Changed the size of magnetic force suffered by vortex rotor by the trend of the Position Control magnetic line of force at the magnetic conductive disk place of annular and power, realize becoming braking moment; To adapt to different braking working condition requirement.And rotor adopts the structure of similar centrifugal blower fan blade wheel, the heat-sinking capability of vortex rotor is improved greatly, temperature rise reduces.
Structure of the present utility model is by axle, retarder shell, magnet, bearing, yoke dish, magnetic conductive disk, magnetic conduction ring gear, form every magnetic patch, vortex rotor, end cap, air inlet air deflector, air inlet control ring, push rod, shift fork, connecting plate and return spring.Wherein, axle makes stairstepping, for installing retarder shell, vortex rotor and end cap.Retarder shell is drum-shaped, is loaded on axle by bearing; It has a circle air admission hole and a circle steam vent.Magnetic conduction ring gear is annular, and magnetic conduction ring gear end face is shaped with the equally distributed magnetic teeth of a circle; Be screwed in retarder shell, magnetic conduction ring gear eases up between fast device shell and is provided with every magnetic patch.End cap is disc, is loaded on axle by bearing; End cap inner face is shaped with that a circle is uniformly distributed, the magnetic teeth identical with quantity with magnetic conduction ring gear end face magnetic teeth shape, together with end cap is screwed with retarder shell.Magnet is annular or fan-shaped, axial charging; Be bonded in retarder shell inner face, for generation of magnetic field.Yoke dish is disc, is bonded together with magnet, plays magnet accumulating cap.Magnetic conductive disk is disc, and external diameter is slightly less than retarder shell and magnetic conduction ring gear internal diameter, magnetic conductive disk internal diameter slightly larger than with magnet, yoke dish external diameter; Magnetic conductive disk can slide between four.Magnetic conductive disk is shaped with annular, has the air inlet control ring that a circle air inlet controls annular distance.Vortex rotor adopts the structure of similar centrifugal blower fan blade wheel, between the rotor disk of two panels annular, accompany flabellum; The effect of similar centrifugal fan work is produced, to strengthen the heat-sinking capability of vortex rotor during rotation; Vortex rotor is provided with air inlet air deflector, air inlet air deflector has air inlet air deflector hole; Air inlet air deflector matches with air inlet control ring the whether air draft of controlled vortex flow rotor.Vortex rotor is fixed on axle, end face and form air gap between magnetic conduction ring gear and end cap magnetic teeth.Push rod, shift fork, connecting plate and return spring are for driving the position of magnetic conductive disk and restriction magnetic conductive disk; Spring force makes magnetic conductive disk be in left position, and shift fork is used for promoting magnetic conductive disk to the right.
Operation principle: when automobile normal running, spring force makes magnetic conductive disk be in left position; Magnetic conductive disk, at magnet, between yoke dish and retarder shell, forms closed magnetic circuit between magnet, yoke dish, magnetic conductive disk and retarder shell; The magnetic conduction ring gear place magnetic line of force is little, even if vortex rotor rotates, does not also produce eddy current, brakeless power.Now, the hole on air inlet air deflector is closed by air inlet control ring, vortex rotor also not air draft.
When automobile needs retarding braking, shift fork promotes magnetic conductive disk to the right; Make magnetic conductive disk be positioned at magnet, yoke dish and magnetic conduction ring gear place, between magnet, yoke dish, magnetic conductive disk, magnetic conduction ring gear, vortex rotor, end cap and retarder shell, form closed magnetic circuit; Magnetic conduction ring gear and end cap magnetic teeth and the vortex rotor end face air gap place magnetic line of force dense, when vortex rotor rotates, vortex rotor cutting magnetic line produces eddy current; Magnetic field and vortex interaction produce the braking force with vortex rotor direction of rotation.Now, the hole on air inlet air deflector and air inlet control annular distance and overlap, and air enters air inlet air deflector, vortex rotor air draft, take away eddy current produce heat.
According to required braking force, control magnetic conductive disk and be in diverse location, magnetic conduction ring gear and end cap magnetic teeth and magnetic field, vortex rotor end face air gap place power can be made to change; Realize variable braking moment.
Compared with prior art, due to the magnet of variable torque permanent-magnet speed buffer be annular or negligible amounts fan-shaped, easy for installation, magnet is little by eddy current thermal impact; And can realize becoming braking moment to adapt to different braking working condition requirement; Adopt the vortex rotor of similar centrifugal fan impeller structure, the heat-sinking capability of vortex rotor is improved greatly, and temperature rise diminishes.
