Detailed description of the invention
In order to more clearly describe the technology contents of the present invention, conduct further description below in conjunction with specific embodiment.
As it has been described above, vehicle card jaw type electric parking brake of the prior art, housing is divided into upper-lower casing, and lower house is original-pack
There is the middle independent centre-to-centre spacing holding means of reducing gear, motor, Timing Belt, big small pulley and motor and reducing gear, such as
Retainer, rigid spacers etc., the present invention removes independent centre-to-centre spacing holding means, pass through between reducing gear and motor on
The hole, location of lower casing positions whole interior position, and motor uses trip bolt to be fixed on lower casing casing position.Reducing gear
Bearing pin directly coordinate with upper casing positioning sleeve.
In FIG, car braking executor is overall is represented by 10.Vehicle performs brake and belongs to the form of card clamp brake.Shell
Including upper casing 7 and lower casing 1, the internal motor 2 that gear reduction 9, energy delivery mechanisms and offer power are provided of lower casing 1,
Energy delivery mechanisms includes small pulley 5, belt 6 and big belt wheel 15, and whole power is provided by motor in shell 2, motor 2
