In the figure: 1. the brake comprises a brake shell, 2, a driving shaft, 3, a transmission shaft, 4, a driven shaft, 5, a bevel gear, 6, a first friction plate water tank, 7, a second friction plate, 8, a sliding rod, 9, a third friction plate, 10, a rotary joint, 11, a return spring, 12, a guide wall, 13, a connecting rod, 14 and a brake rod.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings, for the purpose of making the objects, technical solutions and advantages of the present invention more apparent.
Referring to fig. 1, the efficient friction type braking device of the embodiment comprises a driving shaft, a driving shaft and a driven shaft, wherein the driving shaft is arranged vertically to the driving shaft, the driving shaft is arranged vertically to the driven shaft, the driving shaft is coaxial to the driven shaft, the driving shaft is in meshing transmission with the driving shaft, the driving shaft is meshed with the driven shaft by means of a bevel gear, the inner end of the driving shaft penetrates through the bevel gear and is connected with the end face of a first friction plate, a sliding rod capable of rotating with a driven shaft and axially moving relative to the driven shaft is sleeved in the driven shaft, the inner end of the sliding rod is connected with the end face of a second friction plate, the outer end of the sliding rod is connected with a third friction plate, the third friction plate is sleeved in a rotary joint with the friction plate, the outer end of the rotary joint is connected with one end of a connecting rod, the other end of the connecting rod is sleeved on the braking rod, the end face of the first friction plate is opposite to the end face of the second friction plate, the end face of the third friction plate is opposite to the friction plate, the sliding rod is coaxial to the connecting rod, and the above structure is a core member of the device, and the working principle is that: the rotation direction of the driving shaft is opposite to that of the driven shaft, the braking force pushed by the braking rod pushes the second friction plate and the first friction plate to perform friction braking through the connecting rod and the sliding rod, meanwhile, the friction braking is also generated between the third friction plate and the friction plate in the rotary joint, and the transmission effect can be greatly improved through two-stage braking.
Since the force transmitted to the connecting rod by the brake lever is not purely horizontal, a guide wall is provided outside the connecting rod in order to ensure the movement track of the connecting rod to improve the braking effect. Meanwhile, in order to enable the sliding rod to drive the second friction plate to leave the first friction plate when no force is applied to the brake rod, a return spring is arranged on the outer end face of the rotary joint and the inner end face of the guide wall. The third friction plate is sleeved in the rotary joint, and can move along with the rotary joint when the return spring generates a return force.
The sliding rod is square, and the driven shaft is provided with a square through hole corresponding to the sliding rod, so that when the sliding rod rotates along with the driven shaft and receives axial force, the sliding rod can move correspondingly. The structure is simple and easy to manufacture.
When braking, the driving shaft and the driven shaft rotate in opposite directions and are equal in size, the transmission shaft receives resistance action from the driving shaft and the driven shaft simultaneously, the braking effect is twice that of the unidirectional friction type brake, and increasing the meshing diameter of the bevel gear on the transmission shaft is equivalent to increasing the resistance arm, so that the braking effect can be enhanced.
The foregoing is a further detailed description of the invention in connection with the preferred embodiments, and it is not intended that the invention be limited to the specific embodiments described. It will be apparent to those skilled in the art that several simple deductions or substitutions may be made without departing from the spirit of the invention, and these should be considered to be within the scope of the invention.
