Brief description of the drawings
Fig. 1 is the schematic diagram of braking automobile failure emergency braking apparatus of the present utility model.
Embodiment
The utility model is done below in conjunction with the accompanying drawings and further explained.
As shown in figure 1, a kind of braking automobile failure emergency braking apparatus is fixed on automobile chassis, including Electronic Control list
Member 1, regenerative braking module 2, friction catch module 3, brake force input gear 4.Brake force input gear 4 subtracts with automobile primary
Fast device driven gear engagement, it is usually above and below choosing or right and left to choose in suitable gear tooth matching angle, actual installation
, into the symmetrical position of engagement, determined to main reducing gear driving gear according to automobile chassis real space.Regenerative braking module 2
Including battery 6, electric-controlled switch 7, generator 8, brake force input gear 4 connects the input shaft of generator 8 by power transmission shaft, stores
Battery 6 is connected by electric-controlled switch 7 with generator 8, the control end connection electronic control unit 1 of electric-controlled switch 7.Friction catch mould
Block 3 includes left friction plate 9, right friction plate 10, left electric pushrod 11, right electric pushrod 12, left electric pushrod 11 and right electronic pushes away
The control end of bar 12 is connected with electronic control unit 1 respectively；Left friction plate 9 is connected with left electric pushrod 11, right friction plate 10 with
Right electric pushrod 12 is connected, and left friction plate 9 and right friction plate 10 are oppositely arranged on the both sides of power transmission shaft, the left He of friction plate 9 respectively
Right friction plate 10 is semicircular structure.
In vehicle complete vehicle normal driving process, brake force input gear 4 keeps nibbling with automobile main reducer driven gear
Close, now electric-controlled switch 7 is off, i.e., generator 8 now is in Light Condition, and coil current is zero, coil base
Originally do not stress, the power of vehicle hardly loses.
The brake signal of automobile is monitored in real time in vehicle traveling process by electronic control unit 1, according to brake signal
Judge when failure fault occurs for braking automobile, while carrying out regenerative braking and friction catch.Wherein, brake signal is to adopt
Collect wheel cylinder brake pressure signal a, when pressure signal a is zero, judge that failure fault occurs for braking automobile.
Wherein, real-time power reclaim braking the step of be：The control electric-controlled switch 7 of electronic control unit 1 is closed, and is now generated electricity
The bringing onto load of machine 8, generator 8 is operated in generator mode, and the kinetic energy of automobile main reducer driven gear is inputted by brake force
Gear 4 and transmission axle driven dynamo are rotated, and the power storage that generator 8 is exported is in battery 6, and this process is by automobile
Kinetic energy is converted to electric energy and stored, and reduces the kinetic energy of vehicle with this, reduces speed.Electric energy in battery 6 can be further
There is provided vehicle-mounted electrical appliance 5 to use, on the one hand rationally on the other hand can also prevent battery from being held after being full of using the energy reclaimed
The damage of continuous charge-carrying belt.
The step of friction catch is：Electronic control unit 1 controls left electric pushrod 11 and right electric pushrod 12 to work simultaneously,
Left friction plate 9 and right friction plate 10 are pressed on power transmission shaft, pass through left friction plate 9, friction of the right friction plate 10 to power transmission shaft
Dynamic braking, i.e., be converted to heat energy by the kinetic energy of automobile, speed reduced with this.In the process, automobile can also be detected in real time
Car speed during failure fault occurs according to braking automobile for rate signal b, electronic control unit 1, by controlling a left side is electronic to push away
The size of bar 11 and the thrust output of right electric pushrod 12 adjusts the friction of left friction plate 9 and right friction plate 10 and the power transmission shaft
Power size；Rate signal b is bigger, and thrust is bigger.According to the anti-lock braking system of automobile itself, when wheel occurs before locking, electronics
Control unit 1 controls left electric pushrod 11 and right electric pushrod 12 to withdraw friction plate, prevents locking situation.If now speed
When signal b is more than zero, electronic control unit 1 repeat said process continue to control electric pushrod friction plate to carry out friction catch until
Automobile stops.
When automobile stops travelling, the control electric-controlled switch 7 of electronic control unit 1 disconnects, and energy recovery module is stopped,
And control left electric pushrod 11 and right electric pushrod 12 to withdraw friction plate, friction catch module from service.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
