Abstract

The invention discloses a parking mechanism. The parking mechanism comprises a brake assembly and a drive assembly, the brake assembly comprises a brake belt wheel used for being mounted on an outputshaft of a gearbox and a brake belt arranged on the outer side surface of the brake belt wheel, the brake belt is provided with a fixed end and a movable end which are oppositely arranged, the fixed end is used for being mounted to a gearbox shell, the movable end is provided with a movable stroke along the circumferential direction of the belt wheel, the drive assembly drives the movable end of the belt wheel to move, so that the brake belt and the brake belt wheel are locked or separated, the drive assembly is used for correspondingly braking the output shaft of the gearbox or unlocking theoutput shaft of the gearbox, by means of the arrangement, the situation that the parking mechanism is impacted due to the fact that the ratchet pawl is adopted for parking can be avoided, so that thecomfort of the vehicle starting process is improved.

Description

technical field [0001] The invention relates to the technical field of motor vehicle brake systems, in particular to a parking mechanism. Background technique [0002] In the existing parking system, the pawl is controlled by the gear selection actuator or the shift cable, and is subjected to its force to rotate around the pawl rotation axis and mesh with the parking ratchet, locking the output shaft or The differential thus achieves the purpose of parking. However, the use of the ratchet and pawl for parking will cause impact during the starting process, which will affect the comfort of the starting process. Contents of the invention [0003] The main purpose of the present invention is to propose a parking mechanism, aiming at avoiding the problem that using a ratchet and a pawl for parking will cause shock in the starting process and affect the comfort of the starting process. [0004] In order to achieve the above object, the parking mechanism proposed by the present...
