No work increases the environmental suitability of the system.
Since the part kinetic energy conversion of the relative motion of draw bar in order to which electric energy stores, is reduced draw bar
The front truck braking of impact after to(for) front truck, to improve the ride comfort of front truck.
The present invention is then converted to the scheme of electric energy relative to by converting hydraulic energy for the kinetic energy of draw bar later, into
One step simplifies intermediate required transmission mechanism, so that the arrangement of system is simpler, while reducing energy loss therein.

Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that described herein, the specific embodiments are only for explaining the present invention, not
For limiting the present invention.
As shown in Figure 1, a kind of caravan brake energy recovering system based on direct acting generator principle proposed by the present invention, packet
Energy recycle device is included, energy recycle device includes movement connecting rod 9, and movement connecting rod 9 is sleeved on inside hook shell 2, fortune
The left end of dynamic connecting rod 9 is stretched out from hook casing cover 6, and hook casing cover 6 is bolted with hook shell 2, forms envelope
Cavity is closed, movement connecting rod 9 can freely move along a straight line in this cavity, and the left end of movement connecting rod 9 passes through spherical hinge and traction
