Description
Technical field
The utility model relates to automobile assembling technical field, specifically the slow reduction of speed device of a kind of live axle oil immersion flabellum resistance.
Background technique
General, automobile retarder is to switch on to the field coil of stator assembly by control circuit, produces magnetic field, and rotor assembly is with system of vehicle transmission part High Rotation Speed, and cutting magnetic line, produces opposing torque, makes vehicle deceleration.There are at present two kinds of structures: electric eddy current retarder and liquid turbine retarder.
An electric eddy current retarder: be equivalent to fill " generator " on transmission shaft, during no electric circuit, contactless nothing wearing and tearing, connect circuit in the time of need to braking, and transmission shaft is just subject to the resistance of electromagnetic field, reaches braking object.Without wearing and tearing but huge structure.The principle of electric eddy current retarder is the same with generator, on transmission shaft, there is stator coil, be fixed on crossbeam and have rotor coil to surround transmission shaft (but profile and generator are far from each other), do not need computer to control, as long as the circuit of closing coil, retarder will produce resistance to transmission shaft.It is bulky, it is expensive to prepare, and heavily more card, bus have and select at present.
Liquid turbine retarder: increase a turbine chamber in gearbox case shell rear end, after braking circuit is opened, make gear box oil produce resistance in turbine and reach braking effect, without wearing and tearing but will increasing heat radiation.Current this gearbox has use on high-grade bus.
Particularly the application on family car is more difficult at general vehicle for daily use for these two kinds of structures, how to design a kind of slow deceleration device of propinquity effect, can either play slow reduction of speed effect, again can be economical and practical, facilitate industrial production, be present stage automobile industry have an important topic to be developed and that solve.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, provides a kind of live axle oil immersion flabellum resistance slow reduction of speed device.
The technical solution of the utility model realizes in the following manner, the slow reduction of speed device of this live axle oil immersion flabellum resistance, its structure is to be provided with shell in the axle body periphery of live axle, shell two ends are respectively arranged with end cap, the end cap inner side at shell two ends respectively and between live axle axle body, be provided with end shaft seal, space between shell, end shaft seal and live axle forms velocity reduction chamber, on one section of live axle axle body in velocity reduction chamber, is provided with pillow block, and pillow block is provided with blade for one week; The blade external profile diameter of a week is less than shell internal diameter; The downstream of velocity reduction chamber bottom is provided with unidirectional oil inlet pipe, and unidirectional oil inlet pipe is communicated with velocity reduction chamber inner chamber through shell; The upstream extremity of velocity reduction chamber bottom is provided with unidirectional oil exit pipe, and unidirectional oil exit pipe is communicated with velocity reduction chamber inner chamber through shell; The downstream at velocity reduction chamber top is provided with unidirectional air inlet pipe, and unidirectional air inlet pipe is communicated with velocity reduction chamber inner chamber through shell; The upstream extremity at velocity reduction chamber top is provided with one-way exhaust pipe, and one-way exhaust pipe is communicated with velocity reduction chamber inner chamber through shell; Velocity reduction chamber top is also provided with excessive pressure decompression valve.
Blade adopts the flat blade of a word or a word to be interrupted flat blade.
On unidirectional oil inlet pipe, be provided with unidirectional oiling valve.
On unidirectional oil exit pipe, be provided with unidirectional draining valve.
On unidirectional air inlet pipe, be provided with breather cheek valve.
On one-way exhaust pipe, be provided with one-way exhaust valve.
The beneficial effect that the utility model compared with prior art produced is:
The design of the slow reduction of speed device of this live axle oil immersion flabellum resistance on live axle is equivalent to set up a turbine chamber, after slow speed decreasing mechanism is opened, oil is driven into rapidly in velocity reduction chamber, and the rotation of live axle is produced to resistance, reaches slow reduction of speed effect; After slow reduction of speed, utilize rapidly gas to advertise oil is discharged to velocity reduction chamber's recycle and reuse, the resistance environment of no liquid oil in velocity reduction chamber, live axle continues normal work, so without wearing and tearing, good heat dissipation, can coordinate skidding system to play certain slow reduction of speed effect to automobile.
The slow reduction of speed device of this live axle oil immersion flabellum resistance can either play slow reduction of speed effect, again can be economical and practical, facilitate industrial production.
The slow reduction of speed device of this live axle oil immersion flabellum resistance is reasonable in design, simple in structure, safe and reliable, easy to use, be easy to safeguard, has good value for applications.
