Technical Field

The utility model relates to a motor vehicle dish calliper field of stopping, concretely relates to two oil outlet dish callipers of stopping of three jars.

Background

Motor vehicles are a great leap of the popularity, largely because their kinetic energy and mobility are not comparable to those of automobiles, and it is clear that positive motor tricycles do not interpret perfectly for both of these characteristics. The people who select the right three-wheeled motorcycle are roughly divided into two types: one is that the rider cannot experience the speed of the two wheels due to the safety, the large size, the triangular design and the stability are necessarily better than those of the two-wheel motor vehicle. Secondly, there are always people who seem to have a sense of speed that does not make them feel pleasurable and comfortable, but rather, they are interested in the comfort of riding.

As such, the front and reverse three-wheeled motor vehicles exist as the children of the motorcycle world, but have extremely high popularity in the field, and create a large number of three-wheeled fans.

But its preceding brake caliper of just, falling tricycle or back brake caliper all control this side braking alone at present, and do not have one kind and can drive the preceding brake caliper of rear wheel braking or the back brake caliper of driving the front wheel braking with of back brake caliper drive rear wheel braking in the braking of preceding brake caliper drive front wheel, and the parking pump of just, falling tricycle at present all exists independently, and the mode of drum braking is mostly, and drum braking parking pump structure is comparatively complicated and occupation space is more.
