Embodiment Construction

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] The asynchronous reset method of the double-support brake booster provided by the present invention is to improve and design the single-support assembly unit in the traditional brake booster into a double-support assembly unit, which mainly includes a pedal force support and an electric power support. Then design corresponding reset units for the pedal force bracket and the electric power bracket, so that when the pedal force disappears, the second group of reset springs drive the electric power bracket to reset first, and the first group of reset springs drive the pedal force bracket to follow-up reset.

[0024] The first group of return springs can be the central springs arranged on the central axis of the brake booster, or the first peripheral springs arranged on the peripheral side of the central axis of the brake booster; the second group of return springs ar...

Abstract

In order to solve the technical problem that the traditional vehicle brake booster reset method needs to pay a lot of force when it can only rely on manual braking, the invention provides an asynchronous reset method for a double-bracket brake booster, which improves The feature is that the double-bracket brake booster includes an electric power bracket and a pedal force bracket. When the pedal force disappears, the second group of return springs drives the electric power bracket to start to reset first, and the first group of return springs drives the pedal force bracket and then Follow-up reset. The present invention proposes a new idea of ​​designing the single bracket of the vehicle brake booster as a double bracket, so that the pedal force bracket can be reset by the first set of return springs, and the electric power bracket can be reset by the second set of return springs. When the motor of the booster fails, the driver does not need to overcome the elastic force of the return spring of the electric power support when manually braking, so the pedal force required to be applied is less than that of the prior art.

Description

technical field [0001] The invention relates to a method for resetting a brake booster, in particular to an asynchronous resetting method for a double-support brake booster. Background technique [0002] The traditional vehicle brake booster mostly adopts the structure of single bracket and intermediate reset. During reset, the bracket is reset by the intermediate reset spring, so that the pedal force transmission unit and the electric power transmission unit are driven by the bracket to reset at the same time. For example, the public number is CN. 107949509 A, the brake booster disclosed in the patent documents with the publication number of CN 106427966 A and the authorized publication number of CN 105398440 B. The disadvantage of this reset method is that when the motor of the electric power generation unit fails, when the driver manually steps on the brake pedal to brake, a large force is required, which increases the driver's burden.
