Problems solved by technology
[0002] In the braking system, the transmission ratio of the brake pedal directly affects the pedal feel. During the product development process, it is usually necessary to trial-manufacture a series of brake pedals with different transmission ratios for real vehicle verification to obtain a better brake pedal feel. Increase the development cost, and also need to change equipment frequently, increasing labor intensity

The invention discloses a transmission ratio changeable pedal mechanism. The pedal mechanism comprises a pedal and pedal arms connected with the pedal; the pedal arms are dividedly arranged as an upper pedal arm and a lower pedal arm, the end face adjacent to the upper pedal arm and the lower pedal arm is arranged as an end part inclined plane which is symmetrical relative to axis of symmetry, a, and the extension cord of the end part inclined plane of the upper pedal arm is capable of intersecting with the extension cord of the end part inclined plane of the lower pedal arm; the upper pedal arm is separately connected with the lower pedal arm by a guide element and an elastic connecting piece, and an adjusting piece which is used for adjusting the distance between the upper pedal arm and the lower pedal arm and can move along the axis of the symmetry, a, is arranged between the upper pedal arm and the lower pedal arm; thus, the transmission ratio of the pedal mechanism can be adjusted, the brake system development cost can be reduced and the work intensity is reduced.
Description
technical field [0001] The invention relates to a pedal mechanism with variable transmission ratio. Firstly, the pedal mechanism is equivalent to the ordinary pedal mechanism to realize pedal force transmission, and secondly, the pedal can realize continuous adjustment of transmission ratio. Background technique [0002] In the braking system, the transmission ratio of the brake pedal directly affects the feeling of the pedal. In the process of product development, it is usually necessary to trial-manufacture a series of brake pedals with different transmission ratios for actual vehicle verification to obtain a better brake pedal feel. This not only Increase the development cost, and also need to change frequently at the same time, increase labor intensity. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention researches and invents a variable transmission ratio pedal mechanism to obtain an optimal pedal feel during the deve...
