The electronic brake pedal is connected with a whole vehicle controller through an electronic brake pedal signal line, the pressure sensor is connected with the whole vehicle controller through a pressure sensor signal line, and the signal output end of the whole vehicle controller is connected with a motor of a differential mechanism on a rear axle shaft through a signal line. By means of the air brake energy recycling system, an electric vehicle has the brake energy recycling function, and it is guaranteed that the traditional brake performance of the vehicle is not changed.
Description
Technical field
The utility model relates to a kind of compression air brake energy-recuperation system, belongs to electric automobile energy saving technical field.
Background technology
One of main conservation measures of electronlmobil, for braking energy reclaims, regulates the mode of the gentle compacting power of motor braking power at present with ABS system unit, be widely adopted.But which configuration is complicated, and cost is high, and restive.
The object of braking energy removal process be when braking as far as possible the many motor that allows brake, but can not make total braking force increase, generally adopt at present the size of ABS electromagnetic valve adjustable pressure braking force, because electromagnetic valve is switch valve, for guaranteeing brake comfort, control ratio to electromagnetic valve is higher, and can slattern a part of air pressure to the adjusting of electromagnetic valve.
Summary of the invention
The purpose of this utility model is to provide a kind of compression air brake energy-recuperation system, and it makes electronlmobil possess braking energy recovering function, and guarantees that automobile traditional braking performance is constant.
The technical solution of the utility model is achieved in that a kind of compression air brake energy-recuperation system, it is characterized in that: on the brake piping after electronic brake pedal and two between compressed air brake cylinder, seal in by pass valve, common check valve and pressure sensor, wherein by pass valve is in parallel with common check valve, opposite direction, be by pass valve direction for from electronic brake pedal to compressed air brake cylinder, the direction of common check valve is from rear compressed air brake cylinder to electronic brake pedal, electronic brake pedal is connected with entire car controller by electronic brake pedal signal wire (SW), pressure sensor is connected with entire car controller by pressure sensor signal line, the signal output part of entire car controller is connected with the motor of diff on rear axle shaft by signal wire (SW).
Good effect of the present utility model is that it makes electronlmobil possess braking energy recovering function, and guarantees that automobile traditional braking performance is constant.
Accompanying drawing explanation
Fig. 1 is arrangement structure figure of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further: as shown in Figure 1, a kind of compression air brake energy-recuperation system, it is characterized in that: on the brake piping 4 after electronic brake pedal 7 and two between compressed air brake cylinder 3, seal in by pass valve 6, common check valve 5 and pressure sensor 2, wherein by pass valve 6 is in parallel with common check valve 5, opposite direction, be by pass valve 6 direction for from electronic brake pedal 7 to compressed air brake cylinder 3, the direction of common check valve 5 is from rear compressed air brake cylinder 3 to electronic brake pedal 7, electronic brake pedal 7 is connected with entire car controller 1 by electronic brake pedal signal wire (SW) 8, pressure sensor 2 is connected with entire car controller 1 by pressure sensor signal line 9, the signal output part of entire car controller 1 is connected with the motor 12 of diff 11 on rear axle shaft 10 by signal wire (SW).
When brake energy recovering system is used, setting by pass valve 6 pressure limitings is P, when gas circuit pressure is during lower than P, air pressure can not enter brake piping 4 by by pass valve 6 and common check valve 5, and when gas circuit pressure is during higher than P, air pressure can enter brake piping 4 by by pass valve 6, when at this moment air pressure is lower than P, by pass valve 6 is closed, and gas refluxes by common check valve 5, realizes brake piping 4 pressure pressure releases.By increasing the different check valve assurance traditional braking loop of this both direction, normally work.
When braking energy reclaims, entire car controller 1 obtains chaufeur braking requirement T1 by electronic brake pedal 7, at this moment the value T2 of entire car controller 1 monitoring pressure sensor 2, when T2 is zero, illustrate that rate of braking is little, by pass valve 6 is not opened, gas does not flow into brake piping 4, this situation can be carried out braking energy recovery, entire car controller 1 sends brake torque request T1 to motor 12, now the braking force of rear wheel brake 13 is entirely motor 12 braking forces, has realized braking energy recovering function; When T2 is non-vanishing, illustrate that rate of braking is larger, by pass valve 6 has been opened, gas has flowed into brake piping 4, entire car controller 1 sends to motor 12 the braking request of cancelling, avoid trailing wheel 14 prior to front-wheel 15 locking generation whippings, after end of braking, the air pressure of brake piping 4 discharges by common check valve 5.
When system equipment ABS system, good when ground, compression air brake is larger, and by pass valve 6 is in open mode, and newly-increased device can not exert an influence to ABS; Wet and slippery when ground, very little rate of braking will cause wheel lockup, although at this moment by pass valve 6 is not opened, but when trailing wheel 14 wheel speed fast reducing, due to motor 12 characteristics, the motor 12 revolutions braking force that motor 12 provides when lower is also lower, so motor 12 brakings can not cause rear lock.So this patent configuration is on the not impact of ABS system.
