Detailed Description
A double-backup large-liquid-volume electronic power-assisted brake comprises a first electronic power-assisted brake and a second electronic power-assisted brake, wherein the first electronic power-assisted brake comprises a first oil cylinder 5, a second oil cylinder 4, a first main push rod 2 and a first power motor 3, the first oil cylinder is connected with the second oil cylinder in series, the first power motor drives the first main push rod to horizontally reciprocate, the rear end of the first main push rod is hinged with a pedal 1, the front end of the first main push rod is connected with a piston rod of the second oil cylinder, the second electronic power-assisted brake comprises a third oil cylinder 6, a fourth oil cylinder 7, a second main push rod 9 and a second power motor 8, the third oil cylinder is connected with a fourth oil cylinder in series, the second power motor drives the second main push rod to horizontally reciprocate, the rear end of the second main push rod is connected with the first main push rod in parallel linkage, the front end of the second main push rod is connected with a piston rod of the fourth oil cylinder, the first oil cylinder is connected with the third oil cylinder in parallel, the second oil cylinder and the fourth oil cylinder are connected in parallel.
Further, the first and second servo motors are servo linear motors, the servo linear motors are commercially available products, and the servo linear motors can be, but are not limited to, dc brushless permanent magnet motors. The servo linear motor converts the rotary motion of the motor into the linear reciprocating motion of the first main push rod and the second main push rod through a mechanical transmission device such as but not limited to a gear set or a roller screw rod.
The utility model discloses a big liquid measure electron booster brake ware of double backup, can be connected the control end of the first hydro-cylinder of first electron booster brake ware and the front wheel braking system of vehicle one side and the rear wheel braking system of opposite side, the control end of second hydro-cylinder is connected with the front wheel of relative one side and the rear wheel braking system of relative opposite side, the control end of the three hydro-cylinders of second electron booster brake ware and the front wheel braking system of vehicle one side and the rear wheel braking system of opposite side are connected, the control end of fourth hydro-cylinder and the front wheel of relative one side and the rear wheel braking system of relative opposite side are connected, a plurality of wheels in the middle of also distribute according to this principle equally. Therefore, each wheel is simultaneously controlled by two different electronic boosters, two cylinders of the two boosters are respectively connected in parallel and then are connected into the ESP or the ABS, and then are respectively connected into a plurality of wheels of the truck through the ABS or the ESP, pedal signals are respectively sent to the two electronic boosters, and double backup of the pedal signals is realized.
Because two electronic boosters are completely the same, pedal signals are also the same, under normal conditions, two electronic booster brakes can generate the same main cylinder pressure basically, but can generate twice brake fluid amount compared with a single booster brake, and because the main cylinders of the two boosters are connected in parallel, automatic pressure balance can be realized through the oil passages connected in parallel. The brake oil is redistributed to each wheel after passing through the ESP and the ABS, so that the braking and the stable control of the vehicle are realized, the requirement of large brake fluid volume of a truck or other large vehicles can be met, and the safe and stable running of the vehicle is ensured.
When one of the electronic boosters fails, the other booster can provide at least half of the braking boosting, and in addition, any failure will inform the ESP or ABS to take over the braking control, thus generating greater braking safety redundancy than a single electronic booster.
Secondly, the utility model discloses an electron helping hand brake only needs two identical electron boosters, connects through parallel connection, need not special master cylinder and complicated control, and simple structure and cost ratio are lower.
In summary, the utility model provides a double-backup large-liquid-volume electronic power-assisted brake,
simple structure, the brake fluid volume is big and compromise the safe backup function simultaneously, low-cost high reliability.
Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
