Description
Technical field
The utility model is related to parking brake technical fields, and in particular to a kind of loading machine parking brake.
Background technology
Existing loading machine parking brake is generally divided into two kinds of forms：Brake drum-type and caliper disc, small sized loader one
As use drum brake, but its brake contact be point contact, contact surface is small, and under braking moment, brake(-holder) block is highly susceptible to wearing,
Brake clearance is small, and brake(-holder) block uses very unfavorable adjustment after a certain period of time.Therefore, the application of spot-type disc brake starts to increase at present
More, existing motor vehicle parking brake generally uses disc type brake, is equipped with braking and executes structure, such as hydraulic brake mechanism, gas
Arrestment mechanism or gas-liquid compages are pressed, but its structure is complex and brake force is little, is not suitable for the loading of large-tonnage
Machine.Existing loading machine caliper disc type parking brake is applied in the loading machine of large-tonnage, and it is long the parking response time generally occur,
The loading machine requirement of large-tonnage cannot be met.
Utility model content
The purpose of this utility model is to solve existing 6T-8T large-duty loaders parking brake to disclosure satisfy that host producer is each
Item technology requirement, control mode is aesthetic in appearance, dependable performance.
The utility model is realized using following technical scheme to achieve the goals above, a kind of loading machine parking brake,
Including brake disc, it being equipped with brake above brake disc, brake includes the relatively-movable bracket in both sides positioned at brake disc, and two
Setting can be moved forward and backward by sliding axle between lateral bracket, carriage inner lateral is equipped with and the separable friction plate contacted of brake disc, system
The middle part of dynamic device is equipped with handle connect with parking brake wire, and handle is rotatably connected with brake, handle and with lateral bracket it
Between be equipped with can drive bracket move cam mechanism.
Preferably, the bracket is respectively arranged on the left side and the right side sliding axle, is slidably connected with shaft in the middle part of bracket, handle and support
It is respectively equipped with cam in the middle part of frame, the protrusion of cam is oppositely arranged.
Preferably, it is equipped with rotatable steel ball between the cam, steel ball rack is equipped on the outside of steel ball.
Preferably, it is equipped with resetting spring at the both sides of the bracket and shaft.
Preferably, the rubber sleeve of sealing is equipped on the outside of the cam mechanism.
The utility model is connected by parking brake wire above parking brake handle, and by taut wire, handle makees thick stick
Face cam makees clockwise movement on rod principle motion transmission brake, friction plate up and down or more pinching action is driven, to control
After vehicle parking, smoothly stop.When vehicle needs movement, parking brake is unclamped, resetting spring simultaneously can be rubbing up and down in brake
The open-top reset of pad, function-stable performance is strong, and control is reliable, disclosure satisfy that the demand of host producer items.
Description of the drawings
Attached drawing 1 is the utility model overall structure diagram；
2 the utility model carrier structure schematic diagram of attached drawing；
Attached drawing 3 is the utility model mounting structure schematic diagram；
About 1. bracket in figure, about 2. friction plates, 3. resetting springs, 4. cams, 5. handles, 6. steel ball racks, 7. rubber
Set, 8. fixing bolts, 9. brake discs.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, the utility model provides a kind of loading machine parking brake, including brake disc 9, brake disc
Top is equipped with the brake for locking brake disc clamping, which includes the relatively-movable support in both sides positioned at brake disc
Frame, direction bracket shown in Fig. 1 is setting up and down, and setting can be moved forward and backward by sliding axle between 1 bracket of upper and lower bracket, in bracket
Side is equipped with separates the friction plate 2 contacted with brake disc, and the middle part of brake is equipped with the handle 5 being connect with parking brake wire, hand
Handle is located in the middle part of brake, is rotatably connected, handle and with being equipped with the cam mechanism that bracket can be driven to move between lateral bracket, when
Rotation is converted by axial-movement by cam mechanism when handle rotates, realizes the clamping of bracket up and down.
The cam mechanism includes the cam being located on the inside of handle and in the middle part of bracket, and the protrusion of both sides cam is opposite to be set
It sets, when handle drives the side cam movement, cam rotation squeezes matched inside cam, realizes and clamps.Bracket or so two
Side is respectively equipped with sliding axle, is slidably connected with shaft in the middle part of bracket, forms three-axis stabilization slide construction.The both sides sliding axle of bracket
With resetting spring 3 is equipped at shaft, resetting spring is arranged along the upper and lower bracket direction of motion.
It is equipped with several rotatable steel balls between cam, steel ball rack 6, when outer cam rotates, steel are equipped on the outside of steel ball
Pressure is uniformly transmitted on the cam of inside, the abrasion between cam can be greatly decreased by medium of the ball as intermediate transmission,
Smooth degree is improved, is prolonged the service life.And the rubber sleeve of sealing is equipped on the outside of the mechanism that outer cam and inside cam are formed
7, isolation is further realized, the service life is extended.
Present apparatus work step：Parking brake is tensed after loading machine parking, lever motion is made by pierce tap fixed handle, transmission is outer
Side cam makees clockwise movement, drives bracket up and down and friction plate to make clamping force up and down, to play clamping brake disc, steadily
Stop vehicle.When vehicle needs movement, parking brake is unclamped, resetting spring simultaneously can be the open-top reset of upper and lower friction plate in brake.
