Description
Technical field
The invention belongs to vehicle brake technology field, more particularly to a kind of anti-rear slip device of car ramp starting.
Background technology
With the fast development of China's economic society, car ownership increases year by year, and traffic route has also been obtained greatly
Improve, but we have seen that the accident of general shipping, trip's passenger stock and family-sized car gives people group still than more prominent
Crowd causes serious life and property loss, wherein it is driver's driving ability or brake system of car to have a class ramp car slipping accident
Caused by defect itself.For the not enough driver of driving experience, when automobile is in parking on ramp and starting, they are frequent
In very nervous state, slipped after making automobile flameout, it is possible to cause to be collided with vehicle below, cause traffic thing
Therefore.
At present, the servicing unit that phenomenon researched and developed is slipped after occurring when being started to walk for car ramp at home and abroad to have occurred
Many kinds, for example：Chinese patent Authorization Notice No. CN203511622U discloses a kind of " wheel on-slip of stopping on hill
Plug ", the program works as automobile according to the tyre width of different model, the one made of plastic wheel on-slip plug for having sufficient intensity
Stop when on the slope, on-slip plug plug in front and back wheel bottom, is then decontroled and hold handle, in the effect of spring force by driver
Under, clamping plate is reinforced on wheel automatically, therefore reaches slope anti-sliding function.
Chinese patent Authorization Notice No. CN205554162U discloses " a kind of anti-rear slip device of automobile ", and the device is in vapour
It is improved on the original vehicle frame of car, driver can be powered by Operation switch to motor, such motor just can band
Hydrodynamic depression bar swings up and down certain angle and stretches out 2-level hydraulic bar, and the voussoir of leading portion can be by the stepper motor on voussoir
Adjust voussoir position, make automobile be in parking safe condition, can effectively prevent parking on ramp and starting when after slip.
Existing apparatus are analyzed with discovery, mainly have following two currently for the anti-rear slip device of automobile and method：One,
When automobile is parked in slope, the anti-sliding plug on front and back wheel pad of artificially going down, the method is cumbersome, it is impossible to meet current people
The automation of appealing, and artificial go down to pad thing and can also suffer from by the danger of car hit below；Two, at present using more side
Case is that the gear or ratchet outside automobile gearbox are blocked with pillar, automobile is slipped from after, and the program needs manual operation, once
Misoperation can also influence automobile normally to start to walk, and traffic accident seriously may occur.In a word, prior art needs artificial behaviour
Make, unnecessary harm can be brought in the case where driver forgets operation.
The content of the invention
The present invention is proposed in view of the above problems, therefore starts to walk to be slipped after preventing it is an object of the invention to provide a kind of car ramp
Device, enables automobile to be slipped after parking does not need any operation to prevent on the ramp, can guarantee that automobile is normally started to walk again.
The purpose of the present invention is achieved by the following scheme.
Slip device after a kind of car ramp starting is anti-, it is characterised in that：It includes helical bevel gear one（1）, spiral circle
Bevel gear two（2）, bolt（3）, individual event bearing（4）, spline（5）, shift fork（7）With hydraulic means（8）, the helical bevel gear
One（1）It is vertically fixed on automobile gearbox output shaft（6）On, the helical bevel gear two（2）With individual event bearing（4）By flower
Key（5）Installed in automobile gearbox output shaft（6）On, the unilateral bearing（4）Inner ring has spline, the shift fork（7）With
The hydraulic means（8）Connection.
The shift fork（7）With the helical bevel gear two（2）By the bolt（3）Connection, shift fork（7）In the liquid
Pressure device（8）Promotion under with helical bevel gear two（2）Along automobile gearbox output shaft（6）To helical bevel gear one（1）
Translation and rotation.
The shift fork（7）The helical bevel gear two（2）Push the helical bevel gear one to（1）Side is carried out to nibble
Close, the shift fork（7）The helical bevel gear two（2）Reverse then with the helical bevel gear one（1）Separate.

Specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 2 is this example inventive embodiment helical bevel gear plan, and helical bevel gear one is vertically fixed on automobile
On output shaft of gear-box, equal state is kept with motor racing, helical bevel gear two is fixed on unilateral bearing.When automobile hair
When being slipped after life, helical bevel gear one and helical bevel gear two side faces are engaged and keep stuck.
Fig. 3 is this example inventive embodiment spline plan, is partially improved on automobile gearbox output shaft, is being incited somebody to action
Spline installation is carried out with the engaging portion of helical bevel gear one, helical bevel gear two and unilateral bearing can be made normally to slide
It is unaffected with rotating.When being slipped after automobile generation, helical bevel gear one and helical bevel gear two side faces are engaged and kept
It is stuck.
Fig. 4 is this example inventive embodiment electric operation control circuit figure, and EFI main relays have ignition switch directly to control, work as connection
Ignition switch, electric current enters people's EFI main relay coils, and ECU ECU control dc motors are started, DC motor drive
Hydraulic means, hydraulic means drives shift fork that helical bevel gear two is pushed to helical bevel gear one and carries out side engagement.Direct current
Motor consumption is low, superior performance, strong to environmental suitability, can continuously be worked in having the adverse circumstances such as burn into humidity.Work as vapour
When car is slipped after occurring, helical bevel gear one and helical bevel gear two side faces are engaged and keep stuck.
Fig. 6 is this example inventive embodiment system flow chart, with reference to Fig. 1, Fig. 4, when the driver parks, gravity sensor
Judge whether automobile is parked on ramp, as shown in figure 5, automobile is just parked on ramp, gravity sensor gives automobile signal transmission
ECU ECU, issues instructions to dc motor, dc motor band hydrodynamic pressure immediately after ECU ECU reception processings
Device, shift fork exports axial helical bevel gear one with helical bevel gear two under the promotion of hydraulic means along automobile gearbox
Translation and rotation, after helical bevel gear one and helical bevel gear two are enough tightly engaged, shift fork stop motion, because spiral
Conical gear one is fixed together with automobile gearbox output shaft, i.e., state, helical bevel gear are maintained like with motor racing
Two are even fixed together with unilateral bearing, and unilateral bearing can be moved on spline and can freely turned in automobile direction of advance
It is dynamic, and it is locked in direction of retreat, will be because of helical bevel gear one and helical bevel gear two when being slipped after automobile is just wanted
Engage and keep stuck, make automobile cannot after slip；After vehicle starting, when automobile engine reaches certain rotating speed, installed in song
Tach signal, is passed to ECU ECU by the speed probe startup work on shaft pulley side, and ECU ECU is received
Dc motor is issued instructions to after treatment immediately, dc motor drives hydraulic means, and shift fork is in the presence of hydraulic means
Helical bevel gear two and unilateral bearing are dialled from spline, unilateral bearing can arbitrarily be rotated without spline position, because automobile
Only slip that direction is to maintain locked after and direction of advance is unrestricted, so ensure that automobile need not be normally stood after starting
Quarter reverses helical bevel gear two and unilateral bearing, and helical bevel gear two and unilateral bearing are not worn and torn, so
The device is slipped after effectively preventing automobile.
The present invention is improved on automobile gearbox output shaft, and simple structure is easy to operate, with low cost, can be with
Reduction driver slips after causing because of personal misoperation in uphill starting, reduces property loss.
