Abstract
The utility model discloses a brake pushrod locking device for a vehicle. The brake pushrod locking device for the vehicle comprises a gearbox body, a propelling rod, a support and a parking pawl. The propelling rod is arranged in the gearbox body, and balls are arranged at one end of the propelling rod. The support is arranged in the gearbox body and below the propelling rod. The support is attached to one of the balls in a combined mode. The parking pawl is mounted in the gearbox body through a spring and arranged above the propelling rod. The parking pawl is attached to the other ball in a combined mode. A boss is arranged on the attaching surface of the parking pawl and the other ball. The number of the balls is two. By means of the brake pushrod locking device for the vehicle, residual deformation cannot happen to the parking pawl, a surface cannot be abraded or even fractured, and normal operation can be guaranteed.
Description
Technical field
The utility model relates to a kind of automobile-used braking equipment, particularly a kind of automobile-used brake pushrod Locking Device.
Background technique
Conventional automatic transmission has been used the assembly that is commonly referred to " parking system ", and this component design is for carrying out the relevant function of multiple and Parking of automatic transmission.For example, parking system functional can comprise the forward gear shift select, in moving valve location and/or the Parking pawl activate or set to be used for that automatic transmission is locked onto Parking position or the setting of Parking gear.Though also providing, vehicle is preferably used on relatively steep slope the Parking Brake that separates of Vehicle locking to the Parking setting, but when vehicle on minimum grade or on the relatively smooth landform during Parking, the Parking pawl of parking system generally provides enough Parking gear hold facilities.
The push-rod lock locking apparatus is as the part of parking system, and annexation is comparatively complicated between the part, and with the difference of the size and Orientation of putting forth effort, the contact condition of each parts changes in the course of the work, and structure is state nonlinear.In addition, in loading procedure, residual deformation may take place in ratchet, can make surface wear even fracture when serious, makes it can't proper functioning.
