Description
Technical field
The utility model belongs to the novel rectangular slot structure in caliper technical field, more particularly to a kind of caliper.
Background technology
As shown in Figure 1, piston is retained in braking clamp body by rectangular seal, and rectangular seal is placed in rectangular channel
In.During assembling, rectangular seal and piston interference fit；During braking, piston outward movment compresses rectangular seal, makes rectangle
Sealing ring is deformed；After end of braking, rectangular seal resilience simultaneously drives piston return.Rectangular seal is in piston during braking
It is deformed and displacement under pressure effect, in existing structure, because rectangular channel bevel angle is larger, direction of motion spatial margin
Greatly, it is easier to offset rectangular seal, rather than deformation.Therefore enough screen resiliences cannot be provided after end of braking, is led
It is slack-off that bit rate is got back into activation, causes to drag bigger than normal.As shown in Figure 2, when not braking：Rectangular seal is matched somebody with somebody with piston interference
Close, slight deformation.As shown in Figure 3, during braking：Rectangular seal is moved and deformed along piston movement direction, after rectangular channel
Side space is larger, causes rectangular seal deflection not enough, causes returning place force small.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of that prior art is present, and provides the new square in a kind of caliper
Shape slot structure, changes the structure of rectangular channel, is limited the displacement of the rectangular seal direction of motion, its deflection is improved, so as to increase
Screen resilience, accelerates the seating velocity of piston, reduces sticking of brakes.
The purpose of this utility model is completed by following technical solution, including braking clamp body, piston, rectangular seal
Circle, the piston is retained in braking clamp body by rectangular seal, and rectangular channel is provided with described braking clamp body, the rectangular channel
One side is made up of straight line and oblique line side, and the straight line is connected and perpendicular shape with the base of rectangular channel, oblique line side with it is straight
Line side is connected, and tie point between both sides passes through round-corner transition；Another side of rectangular channel is made up of arc side and bevel edge, should
Arc side is connected with the base of rectangular channel, and bevel edge is connected with arc side.
Preferably, the opening of described rectangular channel is toward the side of piston, and rectangular seal is positioned over the rectangle
In groove, and with the side interference fit of piston.
Preferably, described rectangular channel is located at piston movement displacement side by the side that straight line and oblique line side constitute
To another side being made up of arc side and bevel edge is located at piston return direction.
The beneficial effects of the utility model are：By changing rectangular groove structure, when braking, rectangular seal deflection increases
Plus；After end of braking, bigger deflection produces bigger returning place force, can promptly pull piston return, reduce by
In the sticking of brakes that piston return amount is small and piston return is caused not in time.

Specific embodiment
Detailed introduction is done to the utility model below in conjunction with accompanying drawing：As shown in accompanying drawing 4 to 6, the utility model includes
Braking clamp body 1, piston 2, rectangular seal 3, the piston 2 are retained in braking clamp body 1 by rectangular seal 3, described system
Rectangular channel 4 is provided with moving caliper 1, a side of the rectangular channel 4 is made up of straight line 41 and oblique line side 42, the straight line 41 and square
The base of shape groove 4 is connected and perpendicular shape, and oblique line side 42 is connected with straight line 41, and tie point between both sides passes through fillet
43 transition；Another side of rectangular channel 4 is made up of arc side 44 and bevel edge 45, and the arc side 44 is connected with the base of rectangular channel 4,
Bevel edge 45 is connected with arc side 44.Such structure can make the increase of the deflection of rectangular seal 3, correspondingly increase piston 2 times
Bit rate, reduction is dragged；Increase side chamfer angle simultaneously, facilitate tool sharpening.
The opening of described rectangular channel 4 is positioned in the rectangular channel 4 toward the side of piston 2, and rectangular seal 3,
And with the side interference fit of piston 2.
Described rectangular channel 4 is located at the moving displacement direction of piston 2 by the side that straight line 41 and oblique line side 42 constitute, by
Another side of arc side 44 and the composition of bevel edge 45 is located at the return direction of piston 2.
Operation principle of the present utility model is as follows：As shown in Figure 5, when not braking：Rectangular seal is matched somebody with somebody with piston interference
Close, slight deformation.As shown in Figure 6, during braking：Rectangular seal 3 is moved and deformed along the direction of motion of piston 2, because of rectangular channel 4
Rear side is changed to vertical line, and the displacement of rectangular seal 3 is small, and deflection increases, and correspondingly increases returning place force.Using the rectangular channel
Structure clamp, it is ensured that the smooth return of piston 2, will drag torque and drop to below 2.5Nm.
The utility model is not limited to above-mentioned implementation method, all no matter constitute making any change in its shape or material
It, using structure design provided by the utility model, is all a kind of deformation of the present utility model to be, is considered as new in this practicality
Within type protection domain.
