Embodiment Construction

[0018] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings, but is not limited thereto.

[0019] The dual-motor-driven braking force compensation adjustment device of the present application includes a drive device and an adjustment device.

[0020] Such as figure 1 As shown, the adjustment device includes a brake block 10, a transmission sleeve 11, a pressure sensor 12, and a brake piston 14. The brake block 10 presses the pressure sensor 12 through the transmission sleeve 11, and then presses the brake piston 14 to brake. A change in the position of the piston 14 will change the volume of the cavity storing the brake fluid 15 . When the volume of the cavity changes, the hydraulic pressure of the brake fluid 15 will change (increase or decrease), and the hydraulic pressure of the brake fluid 15 can be adjusted.

[0021] Such as figure 1 As shown, the driving device includes two 12V DC motors 3, 17,...

Abstract

The invention discloses a braking force compensation adjustment device. The braking force compensation adjustment device comprises a driving device and an adjustment device body. The adjustment device body is driven by the driving device and comprises a braking block (10), a transmission sleeve (11) and a braking piston (14). The braking piston (14) is tightly pressed by the braking block (10) through the transmission sleeve (11), and the size of a cavity for storing braking fluid (15) will be changed when the position of the braking piston (14) is changed. The braking force compensation adjustment device is simple and compact in structure and low in cost, the large motor force gain effect is easily achieved, and the double-motor braking force compensation adjustment device has the good universality and is suitable for all small and medium automobiles provided with braking energy recycling devices.

Description

technical field [0001] The invention relates to a device for realizing the compensation of the braking force of automobile machinery based on the drive of double motors. The utility model relates to a novel electromechanical braking force adjustment device, which is used in an automobile braking energy recovery system and belongs to the technical field of mechanical braking systems. Background technique [0002] At present, the brake system used by most automobiles at home and abroad is still based on hydraulic control of mechanical pressure to achieve the purpose of braking. Its principle: During the braking process of the vehicle, when the brake pedal is stepped on, the brake pedal force is amplified by the vacuum booster and output, and applied to the brake fluid. The brake fluid is driven by the output force of the vacuum booster through the oil pipe to the proportional valve, and then push the front and rear wheel brake discs, so that the brake plate of the brake is en...
