Two-wheeled vehicle line control braking structure

Abstract

The invention provides a two-wheeled vehicle line control braking structure. The two-wheeled vehicle line control braking structure comprises a motor, a fixed support, a tapered roller bearing, a locking nut, a screw nut, upper pump push rods, a brake upper pump, a trapezoidal screw and a support with a ball bearing; the motor and the support with the ball bearing are connected to the fixed support; the trapezoidal screw comprises a large end section, a middle section and a small end section which are sequentially connected, and the diameters of the large end section, the middle section and the small end section are gradually decreased; a motor shaft of the motor is inserted into a center round hole of the large end section of the trapezoidal screw, and the relative positions of the motor shaft and the trapezoidal screw are fixed through a jackscrew; the tapered roller bearing is installed on the trapezoidal screw so as to bear axial force generated in the braking process; the screw nut is fixed to the trapezoidal screw through thread fit with the small end section of the trapezoidal screw, and the upper pump push rods are fixed to the two sides of the screw nut correspondingly; and the rotating positions of the upper pump push rods are limited through holes in the support with the ball bearing, and the upper pump push rods can only do translational motion along with the screw nut.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a two-wheel vehicle brake-by-wire structure. Background technique [0002] The braking system of a two-wheeled vehicle is basically composed of four parts: the control part, the upper brake pump, the brake oil pipe, the lower brake pump and the brake disc. Conventional two-wheeled vehicles rely on manual control, and what the control part uses is a brake handle. However, with the development of new two-wheeled vehicles, there was a need for brake-by-wire. [0003] At present, the structure of the brake-by-wire control part used in the test phase of the two-wheeled vehicle is composed of a thrust motor and a brake upper pump. When braking, the thrust motor is controlled by the remote controller. After the thrust motor receives the signal, the upper pump push rod moves upward for a certain stroke to push the hydraulic oil of the upper pump pump, so that the braking force is controlled by ...

AI Technical Summary

Problems solved by technology

[0004] However, the maximum longitudinal size of the brake-by-wire structure controlled by the thrust motor is generally about 400mm, which will take up too much space, and this solution cannot monitor the braking status in real time and control multiple braking methods
