The displacement that core 44 moves is bigger, and for the oil pressure in master cylinder 23 with regard to smaller, hydraulic braking force is smaller, so as to work as automobile high-speed
During braking, increase motor braking power, reduction are rubbed by the conventional friction brake force of hydraulic braking so as to reduce in conventional brake
The abrasion of piece, while improve the rate of recovery of the wheel drive motors M to braking energy.
Optionally, in electric automobile during traveling, if brake coordination component 4 breaks down or battery E is in full power state
When, wheel drive motors M is charged without normal direction battery E and/or generation brake force, and now electric automobile is by hydraulic brake mechanism 2
Braked using conventional hydraulic mode of braking, ensure traffic safety.
Following table is conventional hydraulic mode of braking and method for recovering brake energy used for electric vehicle of the invention under each speed
Braking distance test result.
It was found from the table, caused by method for recovering brake energy used for electric vehicle of the invention and conventional hydraulic mode of braking
Braking effect is essentially identical, and therefore, the present invention, which realizes, is ensureing that both braking makes a concerted effort the situation for meeting automobile brake requirement
Under, the rate of recovery and can that can improve braking energy in braking procedure reduces the loss of conventional brake friction plate.
The brake energy recovering system used for electric vehicle of the present invention, makes electric braking force and hydraulic braking force by mechanical structure
Continuously it is adjusted in real time within the specific limits, eliminates controller in the prior art or single chip circuit calculates control and sentenced
Disconnected process, thus its coordinate braking it is ageing more preferably.
