Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

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

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

Abstract

In order to solve the problem of a reset mode of a traditional vehicle brake booster. When only manual braking can be relied on; the technical problem that large force needs to be paid is solved. Theinvention provides an asynchronous reset method of a double-support brake booster. The double-support brake booster is characterized in that the double-support brake booster comprises an electric power support and a pedal force support, after pedal force disappears, the second set of reset springs drive the electric power support to start to reset firstly, and the first set of reset springs drivethe pedal force support to conduct follow-up reset subsequently. The invention provides a new thought of designing a single support of the vehicle brake booster into double supports. Therefore, the pedal force support can be reset by the first set of reset springs, the electric power support can be reset by the second set of reset springs, when a motor of the vehicle brake booster breaks down anda driver brakes manually, the elastic force of the reset springs of the electric power support does not need to be overcome, and the pedal force needing to be applied is smaller than that in the priorart.

Description

technical field [0001] The invention relates to a reset method of a brake booster, in particular to an asynchronous reset method of a double-bracket brake booster. Background technique [0002] The traditional vehicle brake booster mostly adopts a structure of single bracket and intermediate reset. When resetting, the bracket is reset by the intermediate reset spring, so that the bracket drives the pedal force transmission unit and the electric power transmission unit to reset at the same time. For example, the publication number is CN 107949509 A, the publication number is CN 106427966 A and the authorized publication number is the brake booster disclosed in the patent literature of CN 105398440 B. The disadvantage of this resetting method is that when the motor of the electric power generating unit breaks down, the driver needs to pay a lot of power when manually stepping on the brake pedal to brake, which increases the driver's burden.
