Description
Technical field
The present invention relates to a kind of reverse aid, particularly to the reverse aid in a kind of commercial car.
Background technology
Automobile is paid attention to by increasing people as an electromechanical integrated product, its convenience.And move backward
Whether facilitate, directly affect the convenience of automobile.In passenger car field, general along with electric boosting steering system
And, the function of the convenience such as automatic parking has been used widely.But in commercial car field, owing to it turns to
Axle axle load is more much larger than electric motor car, and electric boosting steering system is difficult to apply, and commercial car is sufficiently bulky, this
The exception allowing for reversing change is difficult.Commercial car, reversing when, in order to safety is moveed backward, has generally been required for people
Conductor driver reversing under car, or driver repeatedly gets on or off the bus observation vehicle backing track, and this allows for cost of labor
Rise, work efficiency drop.If can there be a kind of backing system that driver can be allowed to can be achieved with reversing under car, that
, it is possible to save cost of labor to a great extent, improve reversing efficiency.
Summary of the invention
For deficiency of the prior art, it is desirable to provide a kind of commercial car reversing auxiliary using Electronic control
Device, change needs a people command under car or driver repeatedly gets on or off the bus the situation that just can complete to move backward in the past,
One people of driver just can complete reversing under car, decreases labor cost, reduces labor intensity, improves
Work efficiency.
In order to solve the problems referred to above, this kind of commercial car reverse aid, including: planet circular system, idler gear,
First motor, the second motor and block；
Idler gear is set on steering column for vehicles and engages with the planetary gearsets in planet circular system, the first stepping
Motor drives the sun gear rotation in planet circular system, is provided with multiple bumping post bottom the planet carrier in planet circular system, and second
The outfan of motor is connected with block；
When needs carry out assisting car backing, second step motor drive block rotate be allowed to carrier bottom bumping post support
Connecing, the first motor rotates via sun gear, planetary gear and intermediate gear drives steering column for vehicles successively.
Preferably, the outer wall of the sun gear in described planet circular system is provided with a circle tooth, described first motor defeated
Going out end to be connected with worm screw, this worm screw engages with the tooth on sun gear outer wall.
Preferably, the quantity of described planetary gear is 4；The bottom of described planet carrier is provided with 18 bumping posts；Described
The profile of block is S-type.
It is highly preferred that also include: a U-shaped framework, described steering column for vehicles penetrates from this base of frame, planet
Train and idler gear are arranged in this framework, and the first motor and the second motor are separately fixed at this framework
Sidewall on.
The invention has the beneficial effects as follows: the reverse aid of the present invention needs to coordinate automatic transmission change speed gear box to realize
Move backward under global function, i.e. car or advance.According to the button prompts on remote controller, it is possible to complete work of moveing backward under car
Make.This reversing aid system is easy to process, to former steering column without too much changing when being attached with steering column, logical
Stronger by property.Move backward under car owing to have employed, change need a people to command under car in the past or driver repeatedly
Get on or off the bus and just can complete the situation of reversing, therefore decrease labor cost, reduce labor intensity, improve work
Make efficiency.

Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described further.
In conjunction with Fig. 1 to Fig. 5, this kind of commercial car reverse aid, comprising: planet circular system 1, idler gear 2,
First motor the 3, second motor 4 and block 5, wherein this planet circular system includes intermeshing sun gear
11 and planetary gear 12 and planet carrier.
Concrete annexation is: idler gear 2 be set on steering column for vehicles and with the planet tooth in planet circular system
Wheels engage, and the output shaft of the first motor 3 is connected with sun gear so that it is can drive sun gear rotation, OK
Being provided with multiple bumping post bottom planet carrier in star wheel series 1, the outfan of the second motor is connected with block 5.
Can carry out operating, by " entering on internal control panel-switch of getting off under car when driver needs reversing when
Enter " key, this device enter assisting car backing pattern, the second step motor drive block 5 rotate and with carrier bottom
One bumping post abuts, as in figure 2 it is shown, so planetary gear can only can not revolve round the sun in rotation, subsequently, and the first motor
Rotate via sun gear, planetary gear and intermediate gear drives steering column for vehicles respectively.If needing reversing, only
Need to press " left-hand rotation " key, motor will drive sun gear, and sun gear drives planetary gear, and planetary gear acts on
Steering column, is achieved that the counterclockwise motion of wheel；If needing reversing of turning right, then press " right-hand rotation " key,
Motor just opposite direction rotates, it is possible to realize the right turn movements of wheel；Then " retrogressing " key, remote control are pressed
Device can send to gearshift controller and retreat instruction, and vehicle will slowly be moveed backward by low speed.Due to reversing during,
Can be potentially encountered once reversing cannot successful situation, now vehicle needs to advance, then need to press " advance "
Key, remote controller can send advancement commands to gearshift controller, and vehicle will slowly move ahead by low speed.After having moveed backward,
Pressing " exiting " key, step motor drive block departs from planet carrier, as it is shown in figure 1, now planet carrier freely turns
Dynamic, planetary gear both can also can revolve round the sun in rotation, and steering column can also be freely rotatable and do not affect the normal operating of driver.
In order to obtain the biggest speed reducing ratio, indirectly increase the torque of motor 1.In described planet circular system 1
The outer wall of sun gear is provided with a circle tooth, and outfan and a worm screw 6 of described first motor 1 connect, this snail
Bar engages with the tooth on the outer wall of sun gear.Owing to turbine and worm drive mechanism has auto-lock function, hence in so that too
Sun wheel can only rely on motor 1 to rotate, and planetary gear cannot drive sun gear, and the work that improve this device can
By property.
Preferably, the quantity of described planetary gear is 4, and the bottom of described planet carrier is provided with 18 bumping posts, described
The profile of block is S-type, uses the block of this kind of structure, it is ensured that in block rotation process, do not produce with miscellaneous part
Raw touching, it is ensured that whole system safe and reliable.Additionally, in order to protect this device, also include a U-shaped framework
7, described steering column for vehicles penetrates bottom this framework volume, and planet circular system 1 and idler gear 2 are arranged in this framework,
First motor 3 and the second motor 4 are separately fixed on the sidewall of this framework.
