Description
Technical field
The utility model belongs to fork truck field, and in particular to a kind of novel forklift brake.
Background technology
4~7 ton forklifts include the fork truck of two kinds：4~5 ton forklifts and 5~7 ton forklifts, the structure phase of its brake
Seemingly, all it is the drum brake with automatic force-boosting function, simply variant in size, 4~5 ton forklift brake bands stop in addition
Car arrestment mechanism, 5~7 ton forklift brakes are without parking brake mechanism.4~5 tons and the identical knot of 5~7 ton forklift brakes
Structure is：With back-plate, back-plate is fixed on driving axle of forklift, and back-plate is provided with strip fixed seat, fixed
Respectively there is the groove that a bottom is plane seat left and right ends, and respectively there is a branch being engaged with the trench bottom upper end of left and right brake-shoe
Support face, in the presence of retainer spring, the upper end of left and right brake-shoe abuts against the groove of back-plate at supporting surface
Bottom.During braking, left and right brake-shoe upper end is opened, and the supporting surface of left and right brake-shoe upper end separates with the bottom of back-plate groove,
When brake-shoe is cylindrical to be contacted with brake drum inner headed face, due to the effect of frictional force, left and right brake-shoe around the center of brake,
As brake drum produces a micro rotation, the supporting surface of the upper end of one of brake-shoe is set to abut against back-plate again
The bottom of upper groove, back-plate produce supporting role to it, the supporting role by brake-shoe it is cylindrical on friction material transmission
To brake drum so as to producing brake force.Because the bottom of groove provides planar support to brake-shoe upper end in fixed seat,
Brake-shoe upper end can in calm fixed seat, bottom produce slip in back-plate upper surface for the groove of plane, so brake-shoe
The position of upper end is uncertain, causes the brake brake-shoe return poor performance in use of the two kinds, brakes
It is higher to cross clever and seized probability.It is seized to refer in the not braking vehicle of driver or need to release braking to vehicle
When, brake still provides brake force, causes that vehicle can not travel or travel speed is slow.
Utility model content
The utility model solves the deficiencies in the prior art, there is provided a kind of novel forklift brake, improves brake-shoe
Return performance, so as to prevent braking the generation of clever and seized problem.
Technical scheme is used by the utility model：A kind of novel forklift brake, have back-plate, fixed seat,
Left brake-shoe and right braking hoof, the fixed seat are installed on back-plate, and the fixed seat left and right ends are equipped with bottom and are
The groove of cylinder, the left brake-shoe and right braking hoof upper end are equipped with cylindrical structural, when not braking, the left brake-shoe
Abut against on the face of cylinder of trench bottom, when braking, the left brake-shoe and right braking with the cylindrical structural of right braking hoof
The hoof cylindrical structural of one of them abuts against in fixed seat on the face of cylinder of trench bottom again, another cylindrical structural with
Groove separates.
Preferably, the radius of the cylindrical structural and the radius of trench bottom are same or like.
Preferably, the convex-concave direction of the cylindrical structural and the convex-concave direction of trench bottom are consistent, cylindrical structural
Be hinged matching relationship is formed after being assembled with groove.
Compared to prior art, the utility model has the advantage that：When braking, one of brake-shoe upper end
Cylindrical structural abuts against bottom of the back-plate upper bottom portion for the groove of cylinder, back-plate is played branch to brake-shoe upper end
Support and accurate positioning action；Work as end of braking, during another brake-shoe upper end return, back-plate upper bottom portion is cylindrical
Trench bottom, by the cylindrical structural of the brake-shoe upper end, to the upper end of the brake-shoe, automatic capturing effect is played, makes the system
Dynamic hoof upper end can accurately return to original position, prevent brake in use, return or return be not thorough because of brake-shoe, make
Into braking clever and seized problem.

Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of novel forklift brake, refering to Fig. 1 to Fig. 6, there is back-plate 1, fixed seat 2, left brake-shoe 4 and right system
Dynamic hoof 5, the fixed seat 2 are installed on back-plate, and the left and right ends of fixed seat 2 are equipped with groove 3 of the bottom for cylinder,
The left brake-shoe 4 and the upper end of right braking hoof 5 are provided with cylindrical structural 6, when not braking, the left brake-shoe 4 and right braking
The cylindrical structural 6 of hoof 5 is abutted against in the cylindrical surface of the bottom of groove 3, when braking, the left brake-shoe 4 and right braking hoof 5
The cylindrical structural 6 of one of them abuts against in fixed seat in the cylindrical surface of the bottom of groove 3 again, another cylindrical structural
6 separate with the bottom of groove 3.The cylindrical structural 6 of left brake-shoe 4 and the upper end of right braking hoof 5 respectively with left and right two on back-plate 1
Bottom is engaged for the bottom of the groove 3 of cylinder, left brake-shoe 4 is formed hinged relationship with right braking hoof 5 and back-plate 1.
When not braking, with the upper end of right braking hoof 5 in the presence of brake-shoe resilience spring, its upper end cylindrical structural 6 abuts left brake-shoe 4
In cylindrical bottom of the upper bottom portion of back-plate 1 for the groove 3 of cylinder, back-plate 1 is to left brake-shoe 4 and right braking hoof 5
Upper end play support and positioning action.When braking, left brake-shoe 4 opens to the left and right respectively with the upper end of right braking hoof 5, cylinder
Shape structure 6 separates from the bottom of groove 3, and left brake-shoe 4 continues to open with the upper end of right braking hoof 5, when left brake-shoe 4 and right braking hoof
5 is cylindrical when being contacted with brake drum inwall, and due to the effect of frictional force, left brake-shoe 4 is with right braking hoof 5 in brake
The heart, with brake drum produce a micro rotation, make one of them left brake-shoe 4 or right braking hoof 5 upper end cylinder knot
Structure 6 abuts against on the face of cylinder of the upper bottom portion of back-plate 1 for the groove 3 of cylinder again, and back-plate 1 produces support to it and determined
Position effect, the supporting role by left brake-shoe 4 or right braking hoof 5 it is cylindrical on friction material pass to brake drum so as to produce
Brake force.At this moment the upper end of another left brake-shoe 4 or right braking hoof 5 is in open configuration.During end of braking, upper end, which is in, opens
The left brake-shoe 4 of that of open state or the upper end of right braking hoof 5 return to origin-location in the presence of return spring pulling force.
Wherein, the radius of the cylindrical structural 6 and the radius of the bottom of groove 3 are same or like.The cylindrical structural 6
The convex-concave direction in convex-concave direction and the bottom of groove 3 is consistent.In this example, it is assumed that the radius of groove 3 is set to R.Meanwhile left braking
The upper end of hoof 4 and right braking hoof 5 sets radius and cylindrical structural 6 same or like the radius R of cylindrical groove 3, cylinder knot
The radius of structure 6 is set to R ', after assembling, left brake-shoe, right braking hoof upper end cylindrical structural 6 respectively with back-plate left and right two
Individual bottom is engaged for the bottom of the groove 3 of cylinder, forms hinged relationship.
Embodiment 1, when braking, it is cylinder that the cylindrical structural 6 of the left upper end of brake-shoe 4, which abuts against back-plate upper bottom portion,
The bottom of the groove 3 of shape, back-plate 1 play support and accurate positioning action to it；The cylindrical structural 6 of right braking hoof 5 with
