Problems solved by technology

It is laborious to control the brake pedal with manpower, so many vehicles have added a brake booster on the basis of the brake transmission device. The brake booster includes a booster mechanism. In the prior art, the booster mechanism generally uses a ball screw , but the bearing capacity of the ball screw is small, the cost is high, and in order to prevent the ball screw from reversing during the braking process, it is necessary to add a self-locking mechanism or let the motor output a stalling torque, which complicates the structure

Abstract

The invention discloses an electronic brake booster. The electronic brake booster comprises a motor and a boosting transmission device, wherein the boosting transmission device is driven by the motor and is provided with a rotary / translation conversion transmission mechanism; and the conversion transmission mechanism is used for converting motor rotating drive motion into output motion of translation for operating a brake system. The electronic brake booster is characterized in that the conversion transmission mechanism comprises a thread screw rod and a tooth-formed transmission belt; the thread screw rod comprises a nut and a screw rod; and the motor is in transmission connection with the nut through the tooth-formed transmission belt. By adopting the combination of the thread screw rod and the tooth-formed transmission belt, the motor rotating drive motion is converted into output motion of translation for operating the brake system, so that the cost is effectively reduced, and the transmission torque is increased; and the thread screw rod has a self-locking function, and the thread screw can be fixed to keep on braking in the process of keeping brake force even the motor is interrupted.

Description

technical field [0001] The invention relates to an electronic brake booster. Background technique [0002] Vehicles often include hydraulic braking systems for slowing and stopping the vehicle. It is laborious to control the brake pedal with manpower, so many vehicles have added a brake booster on the basis of the brake transmission device. The brake booster includes a booster mechanism. In the prior art, the booster mechanism generally uses a ball screw , but the bearing capacity of the ball screw is small, the cost is high, and in order to prevent the ball screw from reversing during the braking process, it is necessary to add a self-locking mechanism or let the motor output a stalling torque, which complicates the structure. Contents of the invention [0003] The object of the present invention is to provide an electronic brake booster, which adopts a combination of a toothed transmission belt and a threaded lead screw for boosting, has self-locking performance, and is...
